Owner reports
Selected complaints filed with NHTSA by 2012 Nissan Altima owners, lightly cleaned up (personal details are redacted by NHTSA).
The vehicle is unsafe to driver and others on the road. The power steering hose has had a leak since it was manufactured and was not fixed by the manufacturer at all! Tie rods gave away within 5 years of a mileage less than 24,200 miles. Cv joints along with tie rods have been easily compromised and damaged causing loss of control and steering .suspensions are no longer in tact nor reliable and will pose a danger. All errors were not found by manufacturer and has caused immediate danger to not only driver but everyone on the road. The engine has a rattle only after 2 years which is not usual.
After making right turn onto very busy 4 lane road with cars traveling 55 mph, the car failed to accelerate and had no power. Car acted as though it was in neutral. Fortunately, the road was downhill at this point and after turning on emergency blinking lights was able to coast about 3/4 mile to next street and turn right. I was almost rear ended three times during this coasting period at about 15 mph. On this part of the highway there was no place to pull over as the curb was next to the right hand lane. Had the car towed to a Nissan dealer the next day and was told that the transmission had "totally disintegrated" and was "unrepairable." Cost $4800 to repair. Was told that this was a "common occurrence" with the 2008-2014 CVT Nissan transmissions. Nissan has recalled many CVT transmissions but not 2012. …
I drove out of town about 40 miles and everything was fine, next day went to leave to come home and immediately noticed high RPMs going about 20MPH. I pulled over, turned the car off and turned it back on, started driving and same thing. I had no choice but to drive it on the interstate. I could get up to 60 very carefully but I was still sitting around 4000rpms. It wouldn't shift gears at all (I know it's a CVT and doesn't have gears). I then noticed a high squealing noise, thankfully made it home with a lot of honking and middle fingers even though I had my hazards on. Once I made it home, plugged in my OBD scanner and had a pending DTC of P1778 which I have found to be the stepper motor. Aka the death code. It'll start, shift into all other gears, but is making a high squealing noise even when idle and in park and when revving in park the squeal gets louder. …
The contact owns a 2012 Nissan Altima. The contact stated that while driving at an undisclosed speed and attempting to accelerate, the vehicle briefly lost motive power before slamming into gear. The contact stated that several unknown warning lights were illuminated. The vehicle was taken to the dealer, who diagnosed a failure with the transmission. The vehicle was not repaired for the most recent failure. The contact stated that the vehicle was taken to several independent mechanics after purchasing the vehicle and the mass air flow, spark plugs, sensor coils, and other various engine parts and catalytic converters were replaced; however, the failure persisted. The manufacturer was notified of the failure. The failure mileage was unknown.
3 times car has decelerated when driving on interstate for 1 to 2 hours. Last time speed dropped to 20 mph when most cars were doing 70 to 80 mph. This creates a very dangerous situation that could result in loss of life if not corrected. Nissan refuses to address the matter and problem is well documented on the internet and lawsuits. Nissan should have issued a recall covering the defective CVT. My college age grandson is driving the car as he has no other option but he is putting his life and friends at risk each time he goes on an extended trip. Nissan should at minimum replace the transmission as a safety issue but have denied our claim. Your help would be greatly appreciated.
While driving the car stopped accelerating. Thankfully this happened on a 2 lane road while no other vehicles were around and there was a driveway to pull into. My husband and child were also in the car when this happened. No warning lights/noises alarmed before this happened. We had to have the car towed home. It will turn on but will not drive. This car is notorious for transmission issues. Now we have a car that we can't drive but still owe way more than it's worth to fix. We are unable to trade/sale either. It has been very frustrating situation. We will never own another Nissan.
I have a 2012 nissan altima that I purchased in 2018. in florida. check engine light appeared first. it currently doesn't run because of the transmission. it doesnt excelerate above 20mph. is there is a nationwide recall because of the cvt transmissions going bad?. I already tried to fix 2 separate parts on the transmission the code I'm getting is p1778. I changed the stepper motor and valve body and it's still won't go above 20mph. I don't have 5,000 to replace a transmission. we've been stuck on the road twice in traffic when it doesn't want to excelerate above 20mph
Transmission spudders at times. It is very delayed when pulling out sometimes. Turning the car off and back on might help sometimes. Car will go in limp mode. Nissan dealer said it was the Transmission. There is a big safety concern because when you push the gas trying to cross an intersection, it might lag behind and not go. This could result in being hit. This has been a great car but the cat is complete junk and Nissan should be ashamed of themselves for this. If they get enough law suits they may change something. Well maybe, They don't care about peoples lives.
Transmission lost power (reduced power) after 65000 miles. Initially I was not aware of the Nissan 2012 Altima having transmission issues. Now the repair rather replacement cost is about $5000 as per estimats Iave approached local NISSAN dealerships and national customer service hot line and there has bee ZERO help from them. 2012 is know to have CVT transmission and its related performance and repair issues. Still that year, 2012 , NIssan is not covered under warranty beyond 60K nor there is help for customers who purchased this vehicle
We had a near fatal accident on the highway because the car suddenly lost speed drastically and later on a few incidents won't move up on the slope. My daughter had a hard time reaching home but somehow managed. A quick online research showed many people sharing similar issues due to faulty transmission and sensors. It seems that Nissan is simply hiding behind its 60,000 mile Warranty and not addressing and fixing this issue for the consumers and thereby putting lives at risk.
