Problems with 2012 Nissan Altima POWER TRAIN

I was driving down the highway and my transmission started making a loud whining noise and revved up to about 6400 rpm's and my car had no acceleration from that time on.. now i'm facing either paying $3400 for a new transmission or just trashing a perfectly well kept up car. i've always made sure to have my car completely serviced and maintained on time. after this i will never buy from nissan again. these cvt transmissions are horrible. nissan is looking after their profit instead of reliability. this is a 2012 altima with 125000 miles.

Nissan altima 2012 2.5s model at 115000 miles :without indication the vehicle suddenly could not shift properly when the vehicle started and rpm would go up till 4000-5000, also the vehicle could not run over 65mph: the speed was locked up while rpm kept going up till 3500-4000 i had a near miss from an severe freeway accident because of that problem and dare not drive on freeway after that. the transmission was failing and the mechanic said that the failure pattern was exactly the same as older models(03-10) of nissan altima, where the warranty is extended to 120000 miles for transmission. cost more than 3500 to repair and all the mechanics i met would call those transmission units junk and some of them had multiple nissan altima under repair with the exact same transmission problem.

The car has broke down and can not be drove. it has stalled on us numerous time driving on the freeway in nevada. we have almost been hit by semi truck. the transmission has to be replaced now and the car is not worth the money to fix. it has 123,000 on it.

Nissan altima 2012 s has a bug on the transmission. i have talked to a dealership lately about how i can maintain my transmission to avoid the problem he told me to change the fluid after 60k miles. which i did right away because i was the second owner. i'm supprise at 127k miles, my transmission broken down. and all mechanics i be been to tell me is a factory issue and nissan knows it. they said the cvt transmission mostly come to fail on that nissan after you pass the 100k miles. (factory issue with that cvt technology they said). i call nissan to submit the problem, but unfortunately they told they can't do nothing about it because of the high mileage. the bad transmission is very dangerous on the public road, i have been in the situation on the interstate highway where i couldn't pass the 18 wheeler and almost cause a crash because the transmission is not working properly.

Hello to whom it may concern, i'm posting this complaint because of an issue this vehicle has and i've heard many others are having the same issue. about an hour or two of driving the car or going up a pretty steep hill on a hot day the car looses power completely and will have trouble to go over 45mph and what i've read up on this issue the vehicle come with a sensor that makes the car go into a safety mode when the transmission gets too hot and it's due to the transmission not having a fluid cooler. i've had a couple close calls in the freeway where cars have came really close to rear ending me in the freeway with my children in the car and i fear for the safety of my as well as others and wouldn't want anyone getting sued due to an issue nissan has with their vehicle

While driving on the highway for over an hour at speeds 60+ mph the transmission will begin to whine, while at the same time the rpms will skyrocket. the car will rapidly decelerate while this is happening. this has happened multiple times on road trips when the car was at 20k miles and continues to happen more often now that the car is nearing 100k miles.

2012 nissan altima. consumer writes in regards to transmission issues. *ld the consumer stated the vehicle would abruptly stop on busy highways. no warning lights illuminated. *js

Tl* the contact owns a 2012 nissan altima. the vehicle shifted to limp mode while driving the complainant was stranded on several occasions the cvt transmission cooling system inadequate to cool fluids causing the vehicle to go into safe driving/limp mode. the contact stated that while driving for 45 minutes to one hour,the vehicle shifted into limp mode. there was no warning indicators illuminated. the contact stated that the vehicle decelerated from 70 mph down to 20-30 mph. the contact stated that even with the accelerator pedal down to the floorboard, the vehicle failed to respond. the vehicle was taken to miller auto plaza located at 2900 2nd st s, st cloud, mn 56301, (320) 200-2472, to be diagnosed however, the mechanic was unable to retrieve a fault code. the vehicle was not repaired. the contact stated that the failure recurred on a daily basis. the manufacturer was contacted and informed of the failure, case number: 36304669. the approximate failure mileage was 190,000.piir=y. ah

I have a automatic 2012 nissan altima w. 130k miles. while driving, my car automatically shifted to neutral and in order for me to stop, i had to place my emergency brakes on. the gear was stuck in between neutral and reverse and unable to move. thought it was a shifter console, but turns out it was my transmission. in this model car, there is a class action law suit against nissan for failing cvt transmissions/engines. my failure happened while driving and could have caused a major accident. due to the miles, i am out of warranty and i do believe that nissan should be at fault seeing that there is a suit pending.

After a few hours of driving, the vehicle lost power and went into "limp mode" on an 8 lane highway. after research, nissans have a known problem with the transmission that has yet to he addressed

Cvt problem with transmission delay problem going up hill very scary need transmission looked at i guess problem very common this is a big safety problem almost got hit by car acting up slowing down.

Cvt vehicle loses power when driving on incline on highway

Cvt trans giving check engine soon code p1777 stepper motor cod... trans not shifting properly, it gets stuck at 2000rpms and lags then jump up in rpms. trans shakes hard from time to time while driving at low speeds

18hoz-1diag c check & diagnos (tech 561) complaint: service engine soon light is on also c/s they were driving on freeway in traffic while rpms were around low 1,ooo vehicle would buck from slow speeds trying to accelerate also when vehicle was on a hill at a stop vehicle would not accelerate and started rolling backwards once vehicle gained momentum vehicle started moving please check and advise. cause: verified customers concern. "service engine soon" light is illuminated. checked for dtcs and found multiple dtcs (dtc written on ro). cleared dtcs and none returned after test drive. vehicle did feel a bit sluggish on first test drive. checked fluid levels and found oil level a bit low. also noticed drives floor mat tucked under gas pedal. removed floor mat and test drove again. vehicles acceleration feels normal. went to steep hill to duplicate customers concern. could not verify customers concern. again, correction: replaced both cam position sensors as well as the crank position sensor. cleared all dtcs and test drove vehicle no dtcs returned. vehicle drives fine with no issues.

I purchased the 2012 nissan in 2015 with only 22,000 and something miles. once the car got to about 76,000 something miles a whining noise started. so now with the car at only 83,074 miles the transmission isn't getting any power. so i turn to read reviews and talk to people only to find out the cvt's aren't worth anything and to get them replaced the price is ridiculous and i can't afford it. but you would think with all the complaints about it nissan would do something about it. i would not tell anyone to purchase a nissan ever. also when the whining would take place the car was being driven on city streets or major highways

Driving on a highway and then no acceleration w a high pitch sound...can only drive it 20 mph if at all..had it towed and a mechanic said it is my transmission..as i am researching the problem i am finding a lot of complaints with the same model and year and nissan has to know they have a design issue or problem

The vehicle cvt transmission just stopped going forward and reverse. vehicle has been serviced according to the vehicle maintance recommendations.

Takata recall my 2012 altima has been having some shifting issues while i am driving. mind you this call has 58,000 miles on it (yes 2012 with 58,000). it is over the 5 year power train warranty but under the mileage. nissan does not care. there should be zero reasons why a car with less than 60,000 miles should be having any type of transmission issues. nissan needs to be held accountable.

No forver gear or reverse gear at all .and have alot of code 720 1723 1778 0868 0715 1722 0746 0826 1701

While driving on the freeway for more than 1.5 hours the car suddenly loses power and slows down to 45mph or less or now power at all. because the cvt overheats and shuts down. a nissan dealership inspected it and said we needed a new transmission.

The transmission gave out at 115,000 miles, just below of the cutoff for the extended warranty of the 2010 altimas. the same transmission resides in both of these cars, why is one covered by an extended warranty and the other not?

I am having the same problem with my 2012 nissan altima went to my mechanic and gave me a code of p1778, he told me nissan transmissions have a specific problem with their step motors and that nissan is supposed to fix them for free. i called nissan and they are refusing to fix it when they know their transmissions are not good because they're a lot of people with this same problem. i was driving to work and my vehicle started slowing down it started losing speed that is when i took it to my mechanic, happen o the highway.

My son's 2012 nissan altima has 99,500 miles. the cvt has been acting up multiple times this year. it has gone into the fail-safe mode at least four times on the highway, creating an unsafe and hazardous condition. we've taken the vehicle twice to the local nissan dealer and were told that the transmission had not emitted faults. this is issue should be addressed by the manufacturer. there's obviously an issue that is causing hazardous driving conditions.

The mph would register as 60 but i know it was only doing 20. going around curves it was acting like it want to go but dont go far. it will start but mph wont move, and wont move forward but will backup.

When driving the car for a long distance (30 miles) there is a whining sound that starts and the car will not accelerate. if the car is allowed to sit and cool down the whining will stop but start back as the engine/transmission heats up. during this period the car will loose power and not exceed 40 miles per hour. this happens when driving throughout the city and on the highway

Cvt transmission causing excessive vibrations. it slips and lurches constantly. it shakes when accelerating until 20 mph, and starts again at 20-30 mph. this happens when driving on any roads but it is especially noticeable when decelerating when exiting the highway.

Tl* the contact owns a 2012 nissan altima. while driving 75 mph, the speed reduced to 50 mph without warning. the vehicle was taken to east tennessee nissan (5496 w andrew johnson hwy, morristown, tn 37814, 423-799-3561) where it was diagnosed that the transmission was inoperable. the vehicle was not repaired. the manufacturer was notified and stated that the transmission needed to be repaired. the failure mileage was approximately 132,000.

Cvt, the car jerks, shudders, stalls while driving. this is very dangerous! engine revs on its own, read about the horrible nissan cvt will never purchase a nissan nor recommend to anyone! turning is a nightmare, driving on the highway is quite scary. called customer service nissan does not care! class action suit should be filed asap this is people lives you're talking about !

Nhtsa team, i am filing this safety complaint regarding my daughters 2012 nissan altima. her vehicle has 94,000 miles on it, and the cvt is acting up. this year, the vehicle's cvt has gone into the fail-safe mode at least three (3) times while on interstate trips. each time it was during hot weather (she lives in south carolina) and caused her to run very slowly on the interstate. this created an unsafe and hazardous condition. the nissan dealer is sharing that the only solution is to install a transmission cooler. i think this is more of a manufacturing defect that is causing hazardous driving conditions. please let me know if nissan intends to correct this via a recall for the 2012 altima's cvt. thank you.

Complete loss of power climbing a steep grade uphill, almost caused accident sandwiched between two 18 wheelers also going uphill one of which had to swerve sharply to avoid hitting us. cvt transmission likely went into fail-safe mode, same thing repeated multiple times on steep winding climbs on mountain highways. very dangerous situation with engine cutting out and loss of power. nissan has issued cvt recalls and extended warranty on models up to 2010 but the problem is still there in this 2012 altima and in many other complaints about the cvt on later models. nhtsa should get nissan to extend its recall/warranty to models after 2010 judging by the many complaints being reported about the same loss of power issue with the cvt.

2012 nissan altima. consumer writes in regards to cvt transmission failure. *ld the consumer stated the transmission would to shudder and jerk. the consumer requested assistance with the vehicle repair. *js

Tl* the contact owns a 2012 nissan altima. while driving 75 mph, the vehicle decelerated without warning. the vehicle was taken to larry h. miller nissan highlands ranch (91320 plum valley ln, highlands ranch, co 80129, (720) 907-0718) to be diagnosed. the contact was informed that the failure was due to the transmission overheating, which caused the vehicle to revert to limp mode. the contact was informed that a cooling pump needed to be installed to cool the transmission while the vehicle was being operated. the vehicle was not repaired. the manufacturer was notified of the failure. the approximate failure mileage was 126,000.

Transmission issue with the cvt transmission. whining when accelerating or slowing down going up a hill or going down. nissan extended warranties on earlier models but not the 2012 altima.

Lose of power climbing steep grade at hi altitude transmission over heating. this should not happen.

Initially experienced loss of power around 30,000 miles while going 80 mph on interstate. extremely dangerous situation as the only option is to pull off to the side of the road. took it to dealer but they couldn't replicate or find anything wrong. vehicle continued to randomly lose power while at high rates of speed, as well as a loud whining and humming sound. took to dealership 8 different times and still couldn't find anything. was told if a check engine light came on that would help locate issue. check engine came on during loss of power issue, and dealership still told me couldn't pinpoint problem. the most recent loss of power in june 2018, i was nearly struck from behind by a semi truck travelling at a high rate of speed because there is no warning for the loss of power and there was no where to pull off to. still an ongoing issue, and nissan refuses to acknowledge the problem or do anything to assist.

I have a 2012 nissan altima. i have already replaced the transmission once last year when the car had 80,000 miles on it. the transmission went when traveling on a long trip, after a hours when going approx 65 mph and trying the car failed to acccelerate. the car then would not go over 40 mph. this was a very dangerous situation asthere was a tractor trailer behind me, which forced him to slam on breaks. very dangerous and scarey situation for all involved. again this year while traveling for approx 2 hours the same thing happened. i had to pull off the road on the left had side to avoid an accident. i have read numerous other instances where the same thing has happened. someone is going to be killed or has already been. the 2nd time it happened at approx 99,000 miles. i have already contact nissan and am going to take car for a diagnostic, if i am able to get it there. i believe that other cars for other years have already been recalled due to a class action suit. i have been doing alot of research on this car and year and numerous others have had same complete. very dangerous and deadly accidents will occur if nothing done on nissan part. there is no warning that anything will happen. the lights in the car did not go on, and even after pulling over did not go on

I was driving on the highway when my transmission misfired- my vehicle lost power and went flat at 60mph. i was not able to accelerate above 60mph for the remainder of the trip and the car vibrated excessively quite a bit.

Cvt transmission on the nissan ultima 2012 has been had given me a lot of problems for the past 6 months. upon seeing reviews on the internet in hearing a lot of complaints due to the transmission problems with the nissan baltimore frome yes before the 2012 model up until now that something has to be done to correct this problem with nissan dealers to fix this brow with all the alter most this having a strong with faulty equipment. it is very dangerous to drive by losing power especially if you only in a state will call several accidents due to losing power to upgrade and wanting noise is just creates a big problem moon in a state if you drive-in in your fewer in a major city with the the vehicle slowing down without your control.

When i was driving the cvt starts making noise, the rpm go up to 6,000 rpm then i loose engine power suddenly so the car speed stuck on 40 mph suddenly and decrease the speed even when i press the gas pedal, when i press the gas pedal it just makes noise and increase the rpm and the noise but the speed don't increase, so a car behind me crash tailgating my car, i'm now with seriously injuries, the nissan cvt is defective and dangerous, my car only has 96,000 miles.

My car started making a whining noise while driving it. going up the hill my car on a highway in the desert when the speed declined it's from 70mph to 45mph, which i tried to accelerate and it was stuck on 45mph, and almost caused the car behind me to crash into me with my three young children in the back seat. a lot of complaints have been made and nothing's has been done. what does it take a life to be taken in order for a recall. the transmissions on these cars are crap. every time someone walks into the dealership they seem to be well aware but no recall he been done.

I own a 2012 nissan altima and the car was running good untill 70000. after 70k mile its started making too much noise and at 80k miles its losing power even if i run the gas pedal all the way.the rpm will staty at 2500 at this point.when i researched found out that the cvt transmissions has design falw and most of the cvt transmission has the same issue. i took it to the nissan dealer and they said i have to replace the transmission.i cant believe that nissan cars lasts for only 70k miles. these problems are coming when i am driving on the highway all of a sudden and its very dangerous to drive this car.

Vehicle was in motion on the highway and after two and half hours of driving could not accelerate past 45-50 miles an hour and stuck on this speed even with the gas pedal being pressed down to accelerate. i had serious safety issues with this on the highway in regards to ascending hills and had near serious encounters with trucks and other vehicles on all incidents i have had to drive more than that duration. i am on a website called cargurus and have a lot of nissan 2012 altima owners with the same year, make and model having exactly the same terrifying experience. i have called nissan about this and that they should do a qa of their call logs and check other complaints from other customers and all they could say is "there is currently no recall on your vin". informed them about medicine after death not possible and problems like this with frequent complaints by customers should be investigated and not ignored till people start dying before there is a need to fix this or issue a recall. the gear box and cv axle based on what i have read may be the cause of this. i am not a technician but this is a very serious safety issue that should be investigated. every time you are in a car on the highway on long distance journey with this car your life is on a live wire because of this gear box issue. i have also been to the dealership in south holland il for this and was told to call nissan and complain about this which i have done. i will appreciate your looking into this please! thanks.

While driving, or wanting to drive after coming to a stop, the engine rpms will increase when the accelerator is pressed (up to red line), but the car transmission does not respond until, suddenly, the car lunges forward. this can happen from a cold start, at a traffic light, after a quick stop at a business while the vehicle is still warm, etc.

When driving in warm weather for 1.5 hours or more cvt transmission loses power and makes a whining noise. this is a known issue regarding these transmissions and nissan extended warranty on vehicles up to 2010 because of it. transmission says it is overheating and puts itself into "safe mode" thereby losing all power and ability to accelerate on hills, etc. i was almost rear ended due to the sudden loss of power and acceleration.

Cvt transmission has failed. 6 years old. less than 120,000 miles. stopped at redlight, could not pull out or reverse, car would only go 3-5mph. car engine runs fine.

Driving home from work, turning onto the highway and car won't go above 20 mph and whines terribly.

While driving, either with the cruise control or without, the engine rpms will quickly bounce between high rpms and low rpms though the speed of the vehicle does not change at all. the engine is revving faster, but the transmission does not appear to be engaged. this happens frequently.

The vehicle will not shift out of first gear with its automatic transmission.

The cvt transmission will lose power when driving over an hour on the highway causing the car to drop speed on the highway out of the blue.

I have had to have the engine oil cooler change twice within 14 months of other. and the engine oil sensor.
