Nissan Altima cvt failure problems

Filed Oct 4, 2026 · Engine, Transmission · DC

While operating my 2018 Nissan Altima on September 19, 2026, at approximately 9:20 a.m., during daytime highway traffic, the vehicle suffered a sudden and complete loss of propulsion, leaving me entirely immobilized on a highway ramp with no ability to accelerate or move out of danger. I was stranded in an extremely hazardous location with vehicles, including large commercial trucks, traveling nearby at highway speeds. I feared for my life because I had no way to move my vehicle to safety or protect myself from a potential collision. The situation was so dangerous that a State Trooper with Highway Patrol had to intervene and arrange assistance to have my disabled vehicle removed from the highway. Had Highway Patrol not arrived, I genuinely believe I could have lost my life. This was not a minor inconvenience or an ordinary vehicle breakdown. It was a potentially fatal safety incident caused by the vehicle's sudden and complete inability to move. Following the incident, an independent repair facility inspected the vehicle and determined that the transmission requires replacement. The diagnostic findings included P17F0 (CVT Judder), P0776 (Pressure Control Solenoid B performance/stuck off), and P2813 (Pressure Control Solenoid G control circuit range/performance). Before the complete failure, the vehicle had experienced hesitation, vibration, and difficulty accelerating. I am extremely concerned that this type of transmission failure can occur suddenly while a vehicle is operating in active highway traffic, potentially resulting in a serious or fatal collision. I am requesting that the federal safety agency investigate this incident as a significant vehicle safety concern and determine whether a safety-related defect exists in the CVT transmission system of the 2018 Nissan Altima. I have supporting diagnostic documentation and towing records, and the vehicle is available for inspection.

Shuddering and loss of acceleration/vehicle slowed on its own while driving on the highway. Managed to get to Firestone and diagnostic codes P0776 and P0841 came up. Advised to take vehicle to dealer shop as work could not be done on CVT there. Car was towed to Nissan Bonney Road Virginia Beach. Transmission replacement recommended and my car only has 53,000 miles on it but is outside the 84 month extended warranty drafted from class action lawsuits and settlement. I was not aware of these lawsuit when this vehicle was recommended to me by Hall Honda as Hall Nissan sent it to them for me to see. No additional warranty was given nor was I informed that since the car only had 21,000 miles it was covered under the settlement of 80,000 miles 84,000 month. I WOULD HAVE WALKED, NO RAN, AWAY FROM THIS CAR IF I HAD BEEN TOLD OF THE LAWSUITS. Nissan wants me to pay nearly 6,200.00 for a new transmission that they knew was faulty to begin with. The only other option they gave was that they would give me a 3,000.00 allowance for them to purchase my car and apply that to another (probably faulty) vehicle from them. The issue I have with this is that I still owe 8,700.00 on a car that cost me over 17,000.00 which would make me have to roll the remaining 5,700.00 into another loan. Ludicrous that the dealerships are able to get away with this because they don’t want to admit their cars are faulty! I need Nissan to own up to this and perform a “goodwill” repair at no cost to me for the transmission. Nissan consumer complaints was not helpful at all. The only option I have after this is to file a claim in small claims court which I will probably lose.

My 2016 Nissan Altima has approximately 68,900 miles. When I am stopped and press the gas pedal, the vehicle sometimes hesitates before it begins moving. It does not accelerate normally, which is dangerous when I am pulling into traffic, crossing an intersection, or making a turn. At other times while driving, the vehicle will not accelerate properly and appears to become stuck in a low gear. The engine RPM may rise to approximately 4,000, but the vehicle does not shift or increase speed normally. Turning the vehicle off and restarting it may temporarily make the problem go away, but it can happen again without warning. There is currently NO CHECK ENGINE light or other warning light that has ever come on. So I had the auto parts store attach an OBD-II scanner and the ONLY error code was P0776. This prompted me to research further and that is when I learned of the CVT issues with Nissan. Because the loss of acceleration and failure to shift are intermittent, I cannot predict when the vehicle will hesitate or fail to respond. I am concerned that I could be struck by another vehicle if this happens while entering traffic, crossing an intersection, or attempting to maintain speed.

I am currently experiencing CVT failure as of I have filed a case with the nissan consumer affairs unit, case number 56846043. I was advised that even though there was a class action suit in 2022 for CVT issues, my CVT Warranty Extension expired on 12/09/2024Â for this class action suit. I purchased the car in May of 2025. The dealership failed to mention the class action suit or there were problems with the transmission. Since this is a well known issues, I am requesting help with the cost of repairs.

Transmission stopped working on me in the highway cvt code that comes up is P17f0 was in the highway going 45 mph then dropped 5 mph very dangerous. Almost crashed

The first code it threw was for the master air flow sensor then it started bogging out not going over 1RPM -throwing the code "P17F0 CVT Judder" and has left me in some really,really bad situations in traffic, and when it boggs down like that (no matter how many times I turn it off and restart it, even if the battery drains all the way out and I have to get a jump) I have to wait two hours after unhooking the battery and sit for an hour if not more before I can start it up and actually get down the rd. And it runs great like nothing was wrong it. But doesn't get far before doing it again

I Purchased a 2022 Nissan Altima from Drive Time with 90,000 miles on it. I would have had this car for 2 years this month in May. The Car Currently has about 122,587 Miles on it and has Transmission CVT Failure. I notice pulling, not being able to Accelerate while car was in motion, and while car was stop at green light waiting to procced. while hitting the gas the car would go into limp mode and it would be hard to drive. I've gotten three different diagnose that transmission was getting ready to go out.

The CVT issue remains with this car even though I have complained. The car will randomly de accelerate and randomly accelerate which has cause minor fender bender. The car continue to studer and jerk and continues to show since of transmission issues. These cars need to be recalled before someone is seriously injured from the known CVT issues.

Just bought a 2017 Nissan Altima SR. Took it for a ride. Attempted to merge into traffic and the car had zero acceleration once I merged and then the transmission seemed to completely disengage. The RPMs week to around 3500 so I quickly had to pull off so as not to get rear ended. Brought the car to a stop and attempted several times to push the gas but the car would not pick up any momentum. I eventually turned the car off and waited a couple minutes. I restarted the car and placed it in drive and the car accelerated like a turtle but eventually got up to 30 mph. I turned around and headed back home and parked the car. Calling my mechanic to see if he has any knowledge related to these damn CVT transmission. Not sure why these cars aren't barred from being resold like they did with the Volkswagon. I feel raped.

On August 30, 2025, while driving on the highway, my 2019 Nissan Altima displayed a “CVT (AT) Hot / Power Reduced” warning. Power was limited, but the engine did not shut off. I immediately scheduled service at Paul Miller Nissan in Fairfield, CT. At the September 2, 2025 visit, the repair order stated: “Customer states CVT (AT) Hot Power Reduced display in dash. All past codes stored; cleared all past codes stored.” No complete diagnostic test, CVT pressure test, or fluid inspection was performed. The dealership did not preserve the freeze-frame data from the TCM. I was told that no current fault codes were present and that the vehicle was safe to operate. Relying on the dealership’s professional assurance, I continued normal use of the vehicle. About a couple of weeks later, the vehicle began to jerk and lose smooth acceleration intermittently, worsening by the sixth week. I promptly returned for service. On October 21–22, 2025, the same dealership confirmed transmission codes P0776 and P17F0, diagnosing a CVT failure and recommending full replacement. When questioned about prior diagnostic data, the service manager stated that all data from the September visit had been cleared and that the freeze-frame information was deleted and no longer available. This handling contradicts Nissan’s standard CVT diagnostic protocol, which requires documenting stored codes, inspecting CVT fluid condition, and recording internal temperatures before clearing data. Nissan Consumer Affairs later stated their review relied solely on the dealership’s findings and that missing diagnostic data would not be retrieved. Since the confirmed failure, I have been forced to rent a vehicle at my own expense, exceeding $1000 to date. The vehicle’s reduced power and transmission failure created a serious safety risk, especially as I transport my children in this vehicle. The dealership’s erasure of diagnostic evidence prevented accurate evaluation and timely repair. The issue remains unresolved.
