2018 Nissan Altima: complete transmission failure

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 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.

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.

The CVT transmission failed at the light in mid drive. The car started to roll backwards down a highway exit in traffic. I had to blow the horn and scream out the window to keep from hitting other cars. As the car ascended down the hill, it completely stopped midway and I was unable to remove it from the street. I had to place my hazardous lights on, and push the car off the ramp. I had a Nissan dealership review the vehicle and in return they stated that the actual belt in the CVT was worn down or completely gone and that the entire CVT transmission would have to be fixed. There was no warnings that happened to notify me that there was an actual issue with the vehicle. In addition, I do have a 2015 Nissan Altima who is now showing possible issues with the CVT transmission and it has less than 90,000 miles
