Problems with 2013 Nissan Sentra POWER TRAIN

The transmission keeps slipping. the car has 77,000 miles on it and the dealer is stating the transmission needs to be replaced. cost to replace the transmission is $4,800. apparently this is an issue a lot of nissan owners are having with defective cvt transmission and nissan is not taking responsibility.

While driving 50-60 mph, the car slipped into neutral and would not accelerate. i was able to get to the side of the road safely however, it required me to put it in park and then shift back to drive in order to go. the dealer indicated its a cvt issue, which may be suffering from a 'cvt belt slip condition,' which is the failure of the chain drive to transfer power through the transmission and accelerate the vehicle.the dealer replaced the transmission (under warranty) and the problem is still occurring. the dealer now has the car to discuss with nissan the next steps.

Intermittant engine misfire, car will shut engine off while driving or ramp up rpm causing car to jerk forward. my daughter was driving 45 mph giing around curve when engine shut off , she coast to side of road. restarted and engine started misfiring. check engine flashed and then went steady. diagnostics showed p02 cyc 2 misfire. cyc 2 coil replaced and now two weeks later the car is misfiring, jerking engine was on, drove to nissan dealer they run diagnostic and it came back with no codes in history.

Takata recall. the transmission has gone out on me three times since december 30, 2016. the most recent as of 04/03/2017. i almost got killed each time on the freeway. i would be going 65 mph in the middle of the freeway and it would drop to 45mph and eventually could not function. nissan just replaces the transmission but they keep breaking. therefore they keep failing at fixing the problem within my vehicle and put my life on the line. it is considered a lemon and they agreed which is why they gave me the option for them to buy the vehicle back from me or exchange it. i chose for them to give me my refund. i want a recall on this vehicle and others like it because they risked my life more than once and that should not happen to anyone. they're are families in these vehicles and they're lives should not be at stake like this. i researched that i am not the only one who has suffered with this situation with the same make as my car. i have invoices that i can provide if needed. please take action on this. thank you.

Been driving the car and notice i was hearing a bad roaring noise soon i heard a loud pop in the back of the car and went to look at the drum on passenger side the adjusters screw had completely broke in peace 94k miles been doing this noise on and off and transmission has tendency to feel like it starts to really hesitate badly.

A few times when stopped at the top of a hill, upon proceeding to accelerate into a turn, my car would jerk forward like i was being rear-ended. the second issue with the vehicle, while accelerating, it would randomly start to shake violently. it was hard to pin-point at exactly what speed this occurred, but i'd guess around 40 mph. when i would release the gas pedal the shuddering would stop. although the car has a cvt transmission, sometimes it would feel like the car would shift gears and the car would rumble slightly. i'd say this occurred around 40 mph as well. i took the car to the dealership and learned the transmission needed to be replaced. the car only has 75,000 miles on it. in doing some initial research, i've learned the pathfinders made in 2013 also had similar issues with the transmission.

When idling in drive, reverse, or low, the vehicle stalls with the rpms dropping below 630. no check engine light, no fault codes are found on obdii scanners. transmission is late to engage when accelerating. right before stalling, car will lunge forward and shake. happens when the engine is warm and cold.

Tl* the contact owns a 2013 nissan sentra. while driving approximately 30 mph, the vehicle accelerated and decelerated. the contact also stated that the vehicle jerked without warning. the vehicle was taken to an independent mechanic who diagnosed and changed the oil and filter. the failure recurred and the vehicle was taken to a dealer. the mechanic diagnosed and replaced the brake sensor and flushed the transmission, but the failure recurred. the vehicle was taken back to the dealer where it was diagnosed that the transmission was faulty and needed to be replaced. the manufacturer was not made aware of the failure. the failure mileage was approximately 82,915.

The nissan sentra accelerate and decelerate at any giving moment on the city street in motion, at a stop sign highway turning it shakes and jerks when ever in motion the brakes lock up the vehicle rev and the rpm meter surge unexpectedly and without warning none of the warning lights work the vehicle is very dangerous took the car to the nissan dealer a couple of times they said i needed an oil change got the oil change still didn't help took the car back up there they looked at the car again and said it needed a transmission and i said how no warning lights are on the guy said they want come on until the transmission is gone and the shift lever wont shift in gear without putting an object in the little square hole next to the lever

Earlier last month began having transmission issues, brought the vehicle to dealership with just over the 60k warranty mark. dealer had the cvt fluid changed, which helped for the next day until the issues returned. now i am getting no response from nissan usa and the dealer cannot find the issues because the engine is throwing no codes. almost 2 car accidents. someone needs to do something about this before a person gets into an accident from cvt.

Car will not come from park to drive .car is locked into park.

Tl* the contact owns a 2013 nissan sentra. while driving 20-25 mph, the odometer displayed incorrect readings and the transmission slipped then the vehicle decelerated. the vehicle hesitated while in traffic and the gear shift would not go into the proper gears. also, the check engine indicator illuminated. the vehicle was taken to an independent mechanic who diagnosed that a transmission range performance was needed. the vehicle was repaired two months later. the dealer and manufacturer were not made aware of the failure. the failure mileage was 67,411.

2013 nissan sentra transmission failed at 78,600 miles without any warning while we were traveling on a busy highway on the way home from a long road trip. while driving at an speed of approximately 70-75 mph in tn on the highway the vehicle began decelerate and the rpm's just kept revving up. it was just me (a female) and my two year old daughter in the vehicle. i attempted to the emergency shoulder with my hazards on trying to avoid being hit by a transfer truck and several vehicles. i shut the car off to see what was going on and was afraid of what just occurred. i started the engine back and it began driving fine for about 10 mins on the highway and then it decelerated again near the atlanta area and totally driving power. i was 3 hours from home and had to call for help. i immediately called the dealership the next morning and advised them of the issue and engine codes received from an auto store. i then contacted nissan consumer affairs to notify them of the transmission failure and they advised to simply take it to the dealership for repair since it was outside of warranty. the dealership quoted us a price of $3600 before taxes and advised that they have several issues with cvt transmissions but that's just the nature of them. i have concerns that this is a potential safety hazard while driving on the highway after review and in depth research of the faulty transmission issues several nissan owners have faced in the past few years. additionally, the cost effectiveness of the issue is causing hardship on customers that rely on the brand and safety features nissan is continuing to advertise. nissans commitment: dear nissan sentra owner: nissan is committed to providing the highest levels of product safety, quality and customer satisfaction. (statement is null and void per this concerned customer)

Luckily, i was in my neighborhood, but my transmission just stopped working out of nowhere. the vehicle decelerated and then wouldn't accelerate above first gear. i've seen hundreds of complaints of nissan cvt's that have had the same issue. many people were affected when entering the highway. nissan offered to cover half of the new transmission as mine was only 3,000 miles out of warranty.

While driving on a highway the vehicle began jerking. it also started jumping forward while taking off and experiencing high rpms. it requires a new transmission to fix at only 101,000 miles. just out of extended warranty. *tr

The transmission has a lot of hesitate and bad vibration while driving. check engine light came on and it's due to small evap leak but have replaced cap and still stays on once awhile u smell gas fumes. *tr

Purchased a 2013 nissan sentra with around 45820 miles on it.2 weeks later the transmission goes out. they replaced because it was still under warranty.received it back with problems. rpm would go up past 5 when acceleraring or passing. complained and never received a call back was told that was normal.. problem continues. even had a supervisor test drive and was told nothing was out of order.contact corporate they send me to a new dealer and its gears that are not shifting correctly. solution another transmission this time they expect me to pay but they are willing to pay half.unacceptable for a problem i been complaining about since receiving the vehicle back.obvious defect in transmission for nisan or in mechanics that work for them

'takata recall" i bought my car brand new, i've only had it for 3 years and now i need to replace my transmission. i took my car in for an alignment, i was shown where there is a leak on the transmission. i've taken it to 3 separate mechanics. unfortunately, because its a cvt type of transmission, only nissan is able to fix it! nissan won't budge on the cost of repairs, they have an i don't care attitude about it. it's a [xxx] shame that nissan is building faulty transmissions and won't stand behind their product. i am literally kicking myself in the [xxx] for buying a nissan. once upon a time, nissan was known to make excellent quality cars that were built to last a lifetime. this is my first brand new car, but not my first nissan. i am extremely disappointed! i will never again purchase a nissan! i will discourage everyone i know from buying nissan vehicles! what a disgrace!!!! information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6). *tr

Vehicle wouldn't accelerate going up a small hill. rpm's increased to 4000-5000 range but no power. took to dealership said cvt transmission failure. 83,000 miles, 3 years old.

The transmission on my car has now been replace twice, the car shakes, jolts and shut off. now for a third time while driving on the street the car shock hard and the transmission and engine fell. the car was unmovable. it was so dangerous i was in morning traffic and 3 cars almost hit me because the car stop in the middle of the street. had to get the car towed to the dealership and now waiting to see with what excuse the come out with. car always shakes since i tog it new in 2013. *tr

This car was purchased brand new from dealership, car start giving acceleration problems about 3 moths ago, we just had it diagnosed with the dealership and the transmission is bad and has to be replaced, this car has about 87,000 miles, no transmission should be replaced at this mileage, and we run out of the guarantee. i owe nissans for the las 15 years and never had a problem with my vehicles before they start using the cvt (continues variable transmission), i have the same issue with my 2010 rogue, however the power train guaranty into this model and year was extended to 10 years because of the failure in their cvt transmission, i believe that nissan continues to have issues with this kind of transmission and they should be responsible for fixing all vehicles with this kind of problems. *tr

While traveling on the interstate during morning rush hour, my 2013 nissan sentra started shaking and vibrating. the engine began making sounds, and since i was in stop-and-go traffic, i noticed that when i stepped on the brakes or tried to accelerate, the vehicle wouldn't respond. the rpm meter was jumping all over the place. when i tried to accelerate, my car wouldn't move, and then would jerk forward suddenly. this all made driving on the highway very scary, especially since the problems came about suddenly. i would have to keep an overcautious distance from other vehicles because i wasn't sure when my car would decide to stop or speed up. all of this was happening and the check engine light never came on. the transmission has had a recall before, and i have seen hundreds of consumer reports of others with the same complaint. my vehicle is only 3 years old, i am the first owner, and i have kept up with all service requirements. call the dealership and was told the transmission needs to be replace, that this cars continuing to have this issue since the begining of the cvt transmission on the sentras i think nissan needs to take responsibility for putting cars with unsafe transmissions on the road, my family own many nissan vehicles and they are good products with some exceptions

The transmission will not come out of gear. vehicle will start and come out of gear once you hit the gear shift several times. started the issue last month 09/05/2016. no other incident took place prior. the vehicle was stationary on flat ground in the driveway every time it has taken place. if you put it in park once you finally get it out of park it take about 45 minutes of working with it to get it back out.

Transmission jerks accelerating and decelerating between 15-30 mph. warranty is to 60k, however hundreds (if not thousands) of owners have this issue. resetting the ems module did not fix the issue. car needs a new transmission. a car that was pampered for 77k miles should not need a $3,800 transmission. based the number of owners who have this issue, it is a manufacturer's defect, not an owner's issue. no one should have to deal with problem on a new car. the government should investigate.

My nissan is a 2013 sentra the transmission gave out at 103,000k. 3k over the drive train warranty.

My first indecent occurred while driving down a state highway with my cruise control on, my cruise control was cut off. as i was trying to accelerate back to my driving speed, the gas pedal felt loose and my car was having trouble revving up to accelerate and would not let me accelerate back up to posted highway speeds. the car then "jumped" forward and went back to normal and allowed me accelerate. however, i was not able to engage my cruise control back to normal and would cut it off every time i set it. i took my car to the dealership the next day for an initial recall notice to be fixed and explained also what happened. when i described my issue the service man had said it sounded as if my transmission was slipping, that they would look at it. after recall was cared for and two test drives later, they found nothing wrong with the vehicle. told me if problem comes back to bring in immediately. on 07/06/2016 on my drive home at night, i came to a light and yielded,upon trying to accelerate to turn my car failed to accelerate and was having issues once again revving up! i drifted in to a nearby parking lot, put my car in park, turned it off for a few minutes then turned it back on. it acted fine until i was further down on a state highway and it was giving issues accelerating again. i contacted the dealership the next day (07/07) and was told to bring it in. they called me after sometime, and made me aware of what was wrong with my vehicle(condensation in the tail lights!) and how it was affecting my vehicle. i was also told that it was a manufacturer issue and that the manufacturer and nissan are aware of the issue but have yet to issue a recall!! this is a serious issue that can lead to a fatal accident!!

While driving my 2013 sentra car started to rev amd sputter and hestitating. stepped on gas no power, no check engine lights , radio works but car wuldnt drive driftted out of traffic put car in park. car then would not reverse or drive i believe transmission needs work . car only has 78k on it

With only 69800 miles 2013 , transmission has failed to operate . wont accelarate in ocassions , and the car wont move forward this can cause a crash.

Weston nissan volvo / to whom it may concern in december 2013, i bought a 2013 nissan sentra, from your dealer services weston nissan. so far, i received forever the services from your specialized department, maintenance required by your people in the same place where it was purchased. a few days ago, the vehicle presented a fault according to reports by the mechanic of weston nissan; corresponds to a failure of transmission. that person notified me that the transmission (powertrain) is damaged and have to be replaced at a cost of $ 4000. this transmission was damages because proper maintenance was not performed, as reported by the mechanic. now, as can this be possible? , if the car constantly carry to service according to the warranty and maintenance requirements upon miles. and in the service record, you can see that there is no service for this part. nissan should stand behind their transmission product, reputation and do what is right for all consumers who experience a traumatic and costly situation due to the poor quality and failed transmission. nissan decline to take any responsibility. also, i'm very disappointed because in that short time the car suffered air conditioning problems, replacement gas pump, air bag problems (many times) and more recently serious transmission problem. in my car's service record, there is no evidence of changing air filters and other important car's parts, which gives serious doubts about your service's quality. personally, replace the air filter was never changed. i think there is no reason, if there is been a properly service, to have all this issues with my car. best regards, nhtsa recall 14v-138

When the car sped sometimes begins to vibrate this does at startup until 15 miles and then the car works normally. it is as if in this situation start to happen. by putting the car in neutral does not have this problem.

Purchased nissan sentra 2013 five months ago at 47,000 miles. i have had my transmission replaced 3 times in 4 months. the first 1 time i was on the highway going 65 mph and the vehicle suddenly decelerated, traffic would not allow me to pull over in time. it came to a complete stop in the middle of the highway. i was pushed to the side after people pulled over. the second time i was on the highway and was able to pull to the side when the car decelerated. towed both times. the 3rd time i was pulling into a rest stop a safe area. i was able to start the car back up but it jerked to the garage. i will be afraid to drive the vehicle and my warranty will be over, i am amazed that a car company ignores this with hundreds of complaints.

Left rear tail light was broken, moisture affected propulsion causing an immediate inability to sustain any acceleration almost resulting in an accident with the sudden loss of power while vehicle was in motion.

Transmission doesn't shift smoothly. jerks at high or low speeds. rpms rev up past 5 which requires me to release the accelerator for vehicle to shift. as of jan 3 2019. air bags were fixed during recall. in 2016. however lights came on immediately and never went off. dealer continues to want me to pay for repairs.

Tl* the contact owns a 2013 nissan sentra. while driving various speeds,the accelerator pedal was depressed and the vehicle failed to accelerate. the vehicle was taken to a dealer, but the failure could not be duplicated. the failure persisted. the vehicle was taken back to the dealer for the acceleration failure and routine maintenance. the contact was informed of an air bag warning indicator recall. the dealer repaired the vehicle per the recall, but the remedy failed. the contact mentioned that the air bag warning indicator remained illuminated after the recall repair. the contact was unable to provide the recall information. the manufacturer was not notified of the failures. the failure mileage was approximately 33,000.

Intelligent key fob intermittent start/stop of vehicle. went to start my car after dinner and it would not start.no activity when pressing the intelligent key fob. stranded in a parking lot ,called my spouse and then he came with a spare fob, same thing, no start.turned fob around per owners manual and car started but key warning light flashed all the way home. read manual and made sure all caveats were not the issue. winter weather night outside, came home and pulled car in the garage, waited an hour and tried to start car, no problem started fine. went out next morning and car started fine after two stops, at third stop would not start again. used procedure suggested in owners manual and car started. drove to final destination and no key warning light flashing. went online and found many complaints of dealer related issues with replacement of a steering lock switch to cure problem, (at a cost of around 800 - 900 dollars), at the car owners expense. found some other info online suggesting there is an extended warranty from manufacturer on this item. have not yet researched that claim. also some suggestions to inform nhtsa to start a recall process for this as it seems to be widespread with this make and other models of this manufacturer. i am submitting this complaint in the hopes that others will also and get a recall issued for this. will contact a local dealer for more info on status of manufacturer. twice in 24 hrs is not a coincidence. there is an issue with this system and it should be looked into by nhtsa.

In the evening of 12/23/2015 when entering freeway 101 in ca at the gilroy entrance, i pressed the accelerator pedal in my vehicle in order to reach the freeway speed of 65 mph. when pressing the accelerator i didn't get the acceleration going and i experienced a sudden jerk motion in the car. the car did not accelerate up to the 65 mph and i had to enter the freeway at a speed of about 40-50 mph. if a driver had been entering the freeway behind me at regular acceleration, probably he would had crash into my car. after noticing the lack of acceleration, i felt the car tried to change gears but didn't, experiencing more jerking when pressing the accelerator. after driving in the freeway for 13 miles, i exit the freeway and the checkengine light came on. i was able to drive home and next day drive to the local mechanic for a quick checkup. the local mechanic did a computer diagnosis and determined there was a problem with the transmission and the transmission solenoid. my car has only 73,179 miles and is is pretty unusual that such a driven vehicle fails at this mileage. 2 more diagnostics were run with the computer description stating clutch pressure disengagement performance. transmission fluid levels fine. this kind of failure is inadmissible in a car this old and very dangerous in a highway scenario.

An engineer said that car had been overheating in the transmission for a long period of time. my service team did not know about it. the car failed at 89,000 miles and a month before i owned it 3 years. the engineer said that every 50000 miles the 2013 sentra needs a $4000 plus new transmission. i turned the car on after parking and while turning the car everything seemed fine. i put my foot on the gas and the car would not accerate at all and made chunking noises. i parked the car and called a tow truck. the car had two major checkups at the dealership july-august and was assured that nothing was wrong with the car. engineer said it had been overheating during the time of the major check up. nissan tech at service center swore my car was in perfect working condition.

Tl* the contact owns a 2013 nissan sentra. after starting the vehicle and attempting to accelerate, the accelerator pedal was depressed but the vehicle failed to move forward. the vehicle was towed to a dealer where it was diagnosed that the transmission needed to be replaced. the vehicle was not repaired. the manufacturer was notified of the failure. the failure mileage was 89,000. the vin was unavailable.

Slipping transmission on takeoff and during any type of acceleration. was about creamed by a truck on 301 turning into hampton oaks parkway in tampa fl. no accident, but also had transmission enter a default state where car wouldn't accelerate over 50mph. dealer hasn't fixed and it is an intermittent issue. dealer says they can't reproduce the problem, autoway nissan of brandon.

Tl* the contact owns a 2013 nissan sentra. the contact stated that there was an intermittent failure progressing with the cvt, which caused a strong jerking vibration. the vehicle was also slow to change gears while shifting. as a result, the contact to have to change gears from drive into park and back into drive to try to prevent the failure, which had not worked in most instances when the failure occurred. the dealer (conyers nissan, 1420 iris dr. sw, conyers, ga 30094, (678) 233-2448) initially stated that the power train/transmission assembly needed to be replaced; however, the manufacturer instructed the dealer not to replace the transmission assembly and to replace the valve body. the valve body was replaced by the dealer and, within fifteen days of obtaining the vehicle from the dealer, the condition worsened and the vehicle randomly stalling. in addition, the vehicle failed to accelerate upon changing gears. the vehicle was towed back to the same dealer where the contact was advised that the transmission assembly needed to be replaced and that the vehicle was not included in a warranty campaign. the vehicle was at the dealer awaiting repairs. the approximate failure mileage was 60,000. *tt

Tl* the contact owns a 2013 nissan sentra. the contact stated that the transmission failed multiple times. there were no warning indicators illuminated before or after the failure. the vehicle was taken to berman nissan of chicago (3456 n kedzie ave, chicago, il 60618) where the failure was unable to be duplicated. the vehicle was not repaired. the manufacturer was not notified of the failure. the approximate failure mileage was 20,000. the vin was not provided.

My 2013 nissan sentra has a hard time shifting out of park. i called my local nissan dealer ship's service department. the gentleman told me that he sees this issue at least once a week. i have 57,000 miles on the car so it is no longer under the 3 year 36,000 mile bumper to bumper warranty. it is still under the powertrain warranty, but he said this is not covered under the warranty. he quoted me $199.00 for the labor and $338.13 for the part (shifter assembly).

I have been having problems with the gear shift assembly. i have that online that this has been a known issue with nissan vehicles for the last 15 years. the only way to override the issue is to remove the button on the gear shift and insert a jeweler's screwdriver to compress the lock allowing the vehicle then to shift into reverse. this happen to me several times before i learned about the use of the screwdriver, when it first started the gear shift would occasionally freeze up. i would wait a few seconds restart the vehicle and the gear shift would release. the coast to repair this known manufacture problem ranges from $600 to $900 when you call the dealer about this issue. it just seems like a defect scam that nissan does not want to resolve as they make money fixing their own design flaw. this issue occurs any time your vehicle is in the parked position on the gear shift. it occurs when you start the vehicle, it also happens when you are stuck in traffic and the car is put in to park so you do not have to keep your foot on the break. i have not picture to upload. i am providing the youtube video by nissan that acknowledges the problem exists. https://www.youtube.com/watch?v=b7eriqy9e8a *tr

Tl* the contact owns a 2013 nissan sentra. while driving 50-65 mph, the steering column separated from the vehicle and the air bags disengaged independently. in addition, the vehicle started and the doors locked independently, the vehicle stalled, and the air bags disengaged independently. prior to the additional failures, the vehicle was remedied under nissan's cvt consumer satisfaction program recall. the vehicle was taken to the dealer where it was diagnosed that the spiral cable fractured and the transmission was defective and needed to be replaced. the vehicle was not repaired. the manufacturer was notified. the failure mileage was approximately 80,000.

Tl* the contact owns a 2013 nissan sentra. while driving 65 mph, the transmission blew out. the vehicle was taken to a dealer where it was diagnosed that the vehicle needed a new transmission. the manufacturer was made aware of the issue. the failure mileage was 45,900.

Second failed transmission!!!!! driving on the freeway again and the transmission slammed into low gear. this time my father was driving the vehicle. the first blown transmission was at 20k miles this one failed at 9k miles. odometer reading 29k. this is ridiculous, my family and i are afraid to drive this car. will be filling a complaint with nissan as well. even with a warranty this car is on transmission #3. what happens after the warranty expires??? am i left with a death trap waiting for the next transmission to seize up on the freeway and cause an accident.

This happened on the freeway, transmission slammed into low gear going at 65 mph. pulled off the freeway and luckily duarte nissan in california was less then a mile away. the car barely made it. they replaced the transmission but this was at only 20k miles. the dealership said that this is happening to a few vehicles, but this is dangerous that my car slammed into low gear on the freeway. it scared myself and my family.

As i was driving my car began to jerk. i could not gain any speed and almost cause two accidents because of the way it jerked. *tr

I previously filed complaint, but was now told by the dealership that after the manifold was replaced, that the transmission also needed to be replaced. more waiting time, more unanswered phone calls, more poor service from the dealership. the sentra broke down on 12/20/14 and i'll finally be able to pick up my car on 1/24/15. nhtsa id number: 10672846 summary: my wife was driving on interstate 15 as we left san diego, california. in the car was my adult daughter and my two granddaughters, ages 1 1/2 and 10 months. i was ahead of her in our nissan pathfinder. she called my phone and said that the car rpm's were fluctuating and that the car wasn't going to make it home to twentynine palms. we pulled off the freeway in escondido. i checked the sentra and found that in idle and park that the engine ran fine. when i drove the car, it was lurching like the transmission wasn't shifting correctly. after checking the engine compartment, i drove to a well lite parking lot and while the family ate, i called aaa and had the sentra towed to mossy nissan of escondido. on monday the 22nd, my wife called mossy nissan and told them what happened. they called her back saying that it wasn't the transmission, that a sensor had been taken off of the manifold by her husband or our mechanic. she assured them that since the car was only 13 months old and under warranty, no mechanic had worked on the car and that i had only done the oil changes, but had not worked on the engine. mossy nissan said that they would not honor the warranty since the sensor in the manifold was removed. they referred me to nissan usa, which said the same thing; that since the sensor was missing, they had nothing to turn in for warranty, so they would not honor the warranty. *tr
