Problems with 2012 Nissan Altima POWER TRAIN

Today was the second time i've experienced this dangerous issue while driving on the freeway for about an hour and a half long. my car began to lose speed and would not accelerate above 60 mph. while i had the gas pedal down completely all the way to the floor, as the car could not gain speed. i could have been in a serious accident with all the traffic on the freeway, i had to merge over to the far right for safety. i drove my car immediately after to nissan so they could verify this issue. they failed to help me in any way recommending i invest in a cvt cooler, due to not being covered under warranty anymore. a couple months back when the car was still under warranty i took it to nissan with the same issue, at that time they stated they could not detect an issue. but now my warranty is up they're suggesting what the car needs. i'm very upset with how dangerous this can be and how careless nissan is. it's like they are just waiting for someone to seriously be hurt in an accident to then do something about it.

Purchased car new sep 2012. all manufacturer recommended services completed by nissan dealership service centers. cvt transmission failed jun 10, 2015. failure confirmed by two different nissan service centers.

Cvt transmission was built poorly, the transmission is slowly destroying itself causing a loss of power, high pitched whining noise and eventually fail. the date i selected for when it happened is the date i noticed the issue on my vehicle.

Alright so today i noticed a whining noise coming from the transmission. on my way home from work, just after leaving my car kept slipping out of gear. i get on the highway and the engine light comes on. then im stuck in 5th gear for the rest of the way home. i got the flash codes and did a bit of research, here is what i found. 2012 nissan altima sedan - torque converter clutch circuit intermittent pausible causes: - faulty torque converter clutch solenoid valve - torque converter clutch solenoid valve harness is open or shorted - torque converter clutch solenoid valve circuit poor electrical connection - low transmission fluid level - dirty transmission fluid i have to pull over for about 5 minutes then start my care for the sensor to reset so that i can drive my desired speed limit. once it gets hot the transmission will not allow me to drive more than 60-65mph. the dealer says i need to new transmission. i have 95,000 miles on my 2012 nissan altima 2.5 s and is already having problems. it's difficult for me to travel as much because of these issues. after an hour of driving, my transmission whines and my speed limit drops when driving this is extremely dangerous and deadly. i fear that because of the decrease in speed could be potentially dangerous.

while traveling from sandiego to las vegas, cvt fail safe kicked in while i was in the center lane. lost power and had to make a dangerous lane change, this was the third time this has happened since buying the car in 2012

I was driving on interstate 17 going uphill when all of a sudden my car went into what is known as "limp mode"(loss of power). my speed dropped to 25 mph. i had numerous trucks almost rear end me, until i could limp onto the shoulder. i took it straight to a nissan dealer in flagstaff az. when i got there he pointed to four other vehicles and said to me "what just happened to you, happened to those other 4 nissans right there". i was told by the dealer " you need a transmission cooler installed because of the hot climate we live in this happens all the time, the transmission gets overheated, it's a defect nissan has known about for awhile now". i believe this is a safety issue and it's only a matter of time until someone gets killed when their car looses power on an interstate. i have contacted nissan on numerous occasions only to be told "since no code popped up nothing can be done". the power train is still under warranty. i have tried going through the proper channels with nissan, but it's been in vain. this is a known problem yet they will not recall these vehicles. again sooner or later this will cause an accident and i'm afraid it could be fatal. *tr

We were driving on the interstate at about 70 mph and were unable to accelerate. accelerator peddle all the way to the floor and the most we could go was 45 mph. had the car towed to a nissan dealership and found out it was the shift select assembly that had broken/malfunctioned and the car had gone in to failure mode. there was not warning light at all and this could have been very dangerous on the interstate. first i feel that this part of the car should never have broken in a 2-year old car and i have to wonder if there is a defect in the part for this model year of the altima. second, if and when this piece does break or malfunction, there should be some sort of warning light on the dash to make the driver aware and pull over. nissan is aware of my concerns as i have shared them with their consumer affairs department. *tr

While in operation climbing up and inclines this vehicle engine lose power to approx: 40 - 50 miles and hour, along with a whining in the transmission, also the front suspension appears to be shaking. windows refuse to go up and down. *tr

Car seems to slip into neutral while driving. to resolve this i need to brake, shift into neutral and then back into drive. *tr

Work/repair orders, available on request. it appears to be a common issue with nissan altima's featuring the ctv transmission. 1) purchased the car from hertz, 12/13. 2) acceleration problem noted when first extended trip was taken to bakersfield in 5/14. 3) problem: when the engine was warm the transmission sensor fails and car can not accelerate. car failed going over the "grapevine" in gorman, ca. 4) under nissan 60m warranty, took the car to get checked. car had 59m miles on it. explained the problem. they claimed it was a throttle sensor. fixed it under warranty. 5) next trip to las vegas, going up the i-15 through victorville, aug/2014. the exact same problem occurred. acceleration failed when engine was warm and climbing a gradual incline. 6) took the car back to bp nissan. now they claim to know for sure the problem was not with the throttle sensor but with the ctv transmission. unfortunately they now claim my car is no longer under warranty and requires a $4,000.00 new transmission. 7) after researching the problem it appears this is a common problem for the new altima ctv transmission. they new what the problem was when i first brought the car in with 59m miles on it. they "kicked the can down the road" hoping i wouldn't come back until after the 60m mile warranty expired. dangerous situation having to pull to the side of the freeway. especially with kids in the car. they refuse to give me a "decline of service" letter. please advise. regards, [xxx] information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6). *tr

Altima was serviced at a dealership less than a week ago for oil and filter change. i was driving the 2012 altima from work on 4/10/14. it looked the car was stalling on the highway multiple times. i slowed down and managed to get home, all along it looked like it was going to stop any time, luckily it did not happen. but this morning (4/11/14) it stopped on the driveway stalled after moving 15 feet. towed the car to the dealership to get it repaired. *js

2012 nissan altima. consumer writes in regards to cvt transmission failure. *smd the consumer stated he started noticing little glitches, in otherwise smooth rides. then he started experiencing a 2-3 second delay between depressing the accelerator and the vehicle actually moving. on wednesday april 9, 2014, he was barely able to drive to work, and had to coast with his hazard lights on. the vehicle was towed to the dealer, where the consumer was informed it would cost $ 3911 to fix the cvt transmission.

Tl* the contact owns a 2012 nissan altima. while driving approximately 40 mph, one of the tires flattened. the low tire pressure sensor was not illuminated. when the accelerator pedal was depressed, the vehicle failed to properly accelerate. the failure recurred multiple times. the vehicle was taken to a mechanic who stated that the transmission and transmission axle assembly needed to be replaced. in addition, the transmission fluid pan was cracked. the mechanic was unable to diagnose the tire pressure sensor malfunction. the vehicle was repaired, but the failures recurred. the manufacturer was not notified. the approximate failure mileage was 39,150.

Since when my car had 31,000 miles it's been winging and losing power rapidly, no acceleration, it's a cvt transmission issue. it's a really dangerous car. it's been happening so many times . nissan cvt transmission are very danger. it can cause an accident in the freeway because it can go from 65 mph down to 5 mph rapidly and unexpectedly. please do something about it and protect the life of people.

Cvt transmission and (un)"safe mode" this has occurred on multiple trips on the highway at speeds 60-80 mph that are usually in excess of 70 miles. the vehicles transmission will go into "safe mode". the vehicles transmission will no longer rev above 2900 rpm which inhibits the vehicles ability to maintain safe highway speeds especially if any sort of incline is introduced (it is hard to maintain a speed of 45mph and there is minimal ability to accelerate). the only remedy i have discovered is to let the vehicle cool down. after the first occurrence at ~ 40,000 miles the vehicle was taken to the dealership who stated they could find nothing wrong with the vehicle (codes or obvious defects). after the second occurrence the dealership stated that they could not find an issue, however nissan extended the warranty out to 100,000 miles. the transmission will still go into safe mode from time to time and has additionally began making a quite obnoxiously loud whining noise (at ~ 60,000 miles, similar to when a power steering pump is a about to fail).

Tl* the contact owns a 2012 nissan altima. the contact stated that while driving at 70 mph, the vehicle failed to accelerate and lost power as the check engine light illuminated. the failure recurred several times. the vehicle was taken to the dealer, where it was diagnosed that the po744, cvt a and b temp were found out of specification and the transmission fluid needed replaced. the vehicle was repaired. the manufacturer was made aware of the failure. the failure mileage was 112,000.

On 5/16/2013 after a long period of highway driving my 2012 nissan altima, the vehicle lost power and i was forced to pull over to the right lane in order not to get hit from traffic behind me. after awhile i was able to limp into my local nissan dealer. nissan service said it was a electronic control module (ecm). nissan replace and reprogrammed the ecm under warranty. on 7/11/2013 the same issue returned leaving me in a dangerous situation with no power on the highway driving at highway speeds! again i limped back to my local nissan dealer and this time they diagnosed that i needed a new transmission and they gracefully covered it even though i now had 41k miles. now less than 2 years later 5/13/2015 my car lost power just as it had before on the highway at highway speeds, narrowly getting creamed before pulling over! back to the nissan dealer and at first they reported nothing wrong with my car. i told them it happens when the car is hot, they replied that they couldn't drive it that long! finally after several calls the dealer found a tsb (ntb-13-079) identifying the sensor on the transmission forced it to go into limp mode when the transmission gets hot. nissan's fix is to sell me a $640. transmission cooler. there is a serious defect with these transmissions putting drivers at risk of serious injury and nissan knows about it!
