2018 Nissan Altima transmission 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.

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.

The problem is I have that transmission in my car that nissan was sued for . Yes I received a extended warranty 85 months or 85,000 miles . My transmission started going out as soon I rolled over 85,000. Dealer told me the warranty was no good. Now it's sitting in the yard. All I can do is make the payment. Not only am I making payments but I have to keep insurance and tags for a car I can't drive!!!! I sent nissan an email but I get no response! I desperately need help! My fiancee dream car turned into a nightmare. Thanks! [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

It seems to be the transmission intermittently. I'd stop, push down on the accelerator and would go like a few MPH. Then it would lunge forward and I'd have to slam on the brakes to avoid hitting the vehicle in front of me. The other thing was it didn't seem to shift from first gear - I ended up redlining it at 7000rpm when only going 45mph. I've read that there is a problem with Nissan cars and the CVT. In answer to your questions: You can inspect it. At a stop/light, I'm always afraid the accelerator will start out slow and then lunge forward and eventually I'll hit another vehicle. The dealer couldn't reproduce the issue after having the vehicle 6 days. After 3, they "re-programmed" as the service manager said it was out-of-date and that doing so may fix the problem. They then tested for a further 3 days and couldn't reproduce it. Vehicle has only been inspected by the local Nissan dealer. There were no warning lights or messages before or after these incidents.

I want formally lodge a complaint regarding a serious issue with a 2018 Nissan Altima that I purchased from a Nissan dealership on [XXX]. The vehicle, which had 107,000 miles at the time of purchase, has exhibited a critical failure. On [XXX], while I was accelerating to change lanes in rush hour traffic, the car began jerking and suddenly slowed down. This malfunction nearly resulted in a dangerous collision with an 18-wheeler and caused me to be run off the road. This incident could have been catastrophic, and it deeply concerns me, especially since this vehicle was intended for my daughter's commute to and from school. Following this, I had the car towed to the Nissan dealership and was informed that it requires a new transmission. I am shocked to learn that the cost to replace the transmission is $6,200. This is particularly distressing given that I purchased the car less than four months ago and was unaware of the known issues with the CVT transmission. It is unacceptable that vehicles with faulty transmissions are still being sold without adequate warning or extended warranties. Nissan should be required to provide clear disclaimers about potential transmission issues before a sale. The lack of transparency and the high cost of repairs are deeply troubling. Given the severity of this situation and the potential risks involved, I believe that Nissan should take immediate action to address these concerns. The warranty should be extended, and there should be clear warnings provided to potential buyers about the risks associated with the transmission. The current lack of empathy and action from Nissan is disappointing and unacceptable. I urge you to review this situation promptly and provide a satisfactory resolution.

Car started acting strangely on the way to work one morning, rpms would jump all over, it started to jerk, judder, slow to accelerate. That evening it did the same a few minutes after driving it. Got it to a local trusted mechanic who test drive and ran an OBD2 diagnostic check, which returned a P17F0 code. He told me it's serious CVT issues and referred me to the local Nissan dealership. The next day they called with the same diagnosis, CVT failure. Car was around 99,500 miles. The horrible extended warranty company I chose wouldn't honor it, said the car was fine. Nissan dealer argued that it WAS CVT failure and could cause a hazard. Nevertheless, I picked it up on 05/02. The next evening on the way home from work, in heavy traffic at 50 mph, it started lurching, crazy rpms, shuddering, going into neutral then back to D. As I was turning into a packing lot to stop, the CVT completely failed. The car wouldn't accelerate and left me at an almost stand-still in the middle of the left turn, as incoming traffic nearly crashed into me. A motorist helped push it into the parking lot, where it was towed back to Nissan... where it still sits today with a shot CVT. Nissan refused to help or offer any goodwill assistance even though it nearly caused multiple collisions. The car has been maintained perfectly, with CVT service performed at 65k miles and another at 95k miles. the federal safety agency should mark this issue as a safety hazard as a car that suddenly loses power puts families in danger. A modern car that can't even reach 100k miles before a major failure is pathetic. And Nissan having known about this issue for 10+ years (as made evident by the multiple lawsuits) should be held accountable. One day this massive CVT issue is going to seriously injure someone, or worse.

The transmission would shift into neutral while driving down the road, loosing power to the drive train. This happened multiple times on the interstate at higher speeds in the left lane. Cars following came close to hitting me because of the sudden loss of power and speed. Talking with multiple transmission shops and a dealership they stated it was a common problem in the Nissan Altimas. Brought it into a independent transmission repair. First try was a flush and fluid replacement, after a day the issue returned. Next they replaced the transmission with only about 75,000 miles. No warning lights or messages about the failure.

I bought my car in February 2021 and me not knowing anything about vehicles I first heard the popping noise when I backed my car out of the driveway.I thought it was something to do with the steering wheel. I recently had someone to look at the car and they said it was my front axles going bad, this could be a safety issue. I have to work with mentally challenged people and I have to transport them back-and-forth to doctors appointments. Is there anyway that there could be a recall on those axles because I know someone else who has an Altima just like mine and hers does the same thing . It’s very embarrassing to hear that popping noise and I’m afraid that my car will break down because of it and my front crash light stays on constantly. Please help me resolve this issue. I’ve been dealing with it since I bought the car..
