2012 Nissan Altima: CVT failure

Filed Jul 22, 2025 · Transmission · FL

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. I even attempted the “semi manual’ to see if I could get it to catch, I couldn’t at all. No matter what “gear” I was in it wouldn’t bring the RPMs down.

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

What component or system failed or malfunction and is it available for inspection upon request. The CVT failsafe high fluid temperature protection mode enacted while I was driving on the highway at speeds of 65 to 70 mph going with the flow of traffic it is not available for inspection upon request because this issue only occurs while you're driving down the highway. How was your safety or the safety of others put at risk? My safety and the safety of my passengers and the safety of my fellow commuters was put in jeopardy due to negligence of the manufacturer of the 2012 Nissan Altima when this occurs all acceleration ceases your foot can be all the way to the floor on the gas pedal and your car will not accelerate and in the fast lane on the highway when this happened I became a Sitting Duck in the flow of traffic cars are flying by me and my passengers and I can't get enough speed to change lanes and get out of danger due to a failsafe that Nissan put in these cars on purpose they were fully aware of these issues this is a direct quote from the 2012 Nissan Altima owners manual page 5-17 warning when the high fluid temperature protection mode or fail safe operation occurs vehicle speed may be gradually reduced the reduced speed may be lower than traffic which could increase the chance of a collision be especially careful when driving if necessary pull to the side of the road to a safe place and allow the transmission to return to normal operation or have it reparative necessary. Has the problem been reproduced or confirmed by a dealer or independent service center. Unknown. has the vehicle or component been inspected by the manufacturer police Insurance Representatives or others. Unknown. Where there any warning lamps messages or other symptoms of the problem prior to the failure and when did they first appear. Zero warning lamps no messages just all of the sudden no acceleration and I am in a very dangerous situation which could have cost many people their lives

Hi I’m having trouble with my transmission in my car due to a safety feature that Nissan has installed on there cvt transmissions. After driving for 1 1/2 to 2 hour trips my car does not accelerate or will have a slow time gaining speed. Nissan has a high fluid temperature protection mode that basically when the transmission temp gets too high the computer cuts you off completely and intentionally stops you from going any faster. This is a serious issues if your in traffic or driving somewhere on the highway and not able to move to the side of the roadway or to a median. If my car was to completely stop in the middle of the road due to this safety feature, it could cause collisions and life threatening injuries.

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. Service manager also said that we were "lucky that disintegrated the way it did as some cars locked up in geared and immediately stopped." There was no prior warning of a transmission problem. No lights, no noise, no nothing. There was no way to know a problem or potential failure was imminent. This car is a danger. Had this occurred on a freeway in Los Angeles where we were driving just prior to this failure, it could have caused a major injury accident. This transmission should be recalled. The car had 97,000 miles. Nissan should be required to recall and reimburse owners who have suffered this failure in 2012 Altima transmissions.

I have a 2012 Nissan Altima. Four years ago I drove from Sacramento, CA, to Reno, NV, with two friends in my car. As I was driving over the summit on Highway 80 my car started to lose power. This was extremely scary as the highway is only two lanes and since it was a Saturday there was a lot of traffic. I was driving in the slow lane and as my car continued to lose power and slow there was noplace to get off the road. I pulled onto the narrow sholder between the slow lane and the concrete barrier and my car came to a complete stop. Since there were cars whizzing by I was not able to open either the drivers side door or the passenger side door, which was inches away from the concrete divider. At this point I was shaking uncontrollably and in a panic I called Nissan of Sacramento to tell them what happened. The technician suggested that my transmission may have over-heated. He suggested that I wait for the transmission to cool and see if I was able to then make it to the nearest freeway offramp, which I did. After exiting the freeway we waited for an hour or so and were then able to proceed to Reno, NV. Once there, I took my car to a mechanic who checked the other systems and could find nothing wrong. Once back home in Sacramento I took my car to Nissan of Sacramento and was then informed that my transmission had burned and would need to be replaced. They contacted Nissan and were informed that there were no recalls and that I would need to pay for a new transmission out of pocket and the cost would exceed $4,700. After contacting Nissan myself, they informed me that they would not cover the cost of a new transmission. Since I am a retired, single senior citizen living on a fixed income, I have not been able to replace the transmission and subsequently have not driven more than 20 miles from my home. I have read that CVT Transmission problems are very common with Nissan Altimas. Why would they deny my claim when this is such a serious safety issue?

Car got stuck in a high gear on the interstate. Speed reduced dramatically and went below minimum speed limit (40mph). No warning lights illuminated. My vehicle has had this issue twice within the last 6 years. Took my car to the dealership where I bought it but they said that they didn't have anybody that could check a CVT.

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.

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

Three hours into my drive, I was going about 70 MPH and noticed my car started to slow down and was making a noise. I pulled over, got out, checked my power steering fluid. It was fine so I drove off and as I was entering the freeway, I noticed the car wasn't picking up speed again. I drove to the next exit and got off. I literally coasted to a parking lot of an industrial building. After several attempts at trying to leave the parking lot, I noticed I couldn't go up the hill. I waited about 30 minutes, picked up speed and made it up the hill and onto a 2 lane road. I drove to a hotel about 4 miles away, going about 40 MPH. I realized that as long as I didn't stop, I would be fine. The next morning I found a mechanic shop, called and drove there with minimal problems. He told me the year, make and model of my car had been having issues with the CVT transmission. He hooked a machine up and it gave him these codes: p0746, p0826, p1778 step motor, p0868. He told me to check for recalls. I was able to drive the car 3 hours back to my house in woodbridge.

The car started slowing down in the freeway and it lost power while I was in the carpool so I drove carefully to the emergency lanes on the side risking getting hit by a car cause it didn't have any power or shifting. I though the transmission went bad. I turn off the car for five minutes and started it again and I try to move the car again and it went well. After couple days or weeks I don't recall I call the dealer requesting a recall on my vehicle which they ask me how many miles it had I told them 83,000 miles and they told me I don't qualify to get the transmission replace cause it has over 80,000 miles already. It seems that nissan makes faulty CVT transmission manufactured by jatco. I wanted to know if I qualify for the recall for the transmission. When I reset the car on the freeway for five minutes it ran and hasn't happened again but it's super sluggish. The car should have a recall no matter the mileage. Forgot to mention they said I don't qualify also cause the car is salvage and it voids every recall whatsoever.
