2015 Nissan Altima power train problems

“Subject: Dangerous Transmission Failure in 2015 Nissan Altima While my 2015 Nissan Altima has always exhibited questionable performance—including abnormal acceleration, hesitation during throttle response, and mismatched RPMs relative to acceleration—the transmission has now begun to severely slip. I have also experienced sudden loss of power, pronounced shuddering, and complete power failure while driving. On multiple occasions, these issues have placed me in dangerous driving situations. It is important to note that I have regularly maintained the vehicle and kept it in mechanically decent shape throughout my ownership. I believe it is critical for other drivers to be aware of these ongoing problems, especially since Nissan appears to be avoiding responsibility for manufacturing such faulty powertrains. New car buyers and those purchasing used vehicles are becoming victims of this defective transmission, which poses a serious risk to passengers, drivers, and others on the road.”

“The transmission failed in my 2015 Nissan Altima. The check engine light is currently on due to a defective transmission. While I understand that Nissan extended the transmission warranty by two years or 24,000 miles following a class action lawsuit, I find this coverage completely unreasonable, insufficient and irresponsible, and most importantly unsafe. My vehicle has only 83,800 miles and has been well-maintained, yet the transmission still failed. While driving in the freeway in San Diego, the vehicle suddenly lost complete transmission engagement and power. My vehicle was almost rear ended by multiple cars. The check engine light appeared after the transmission failure. A Nissan dealer later confirmed the vehicle needs a new transmission. Nissan and NHTSA should have done a complete recall after the class action lawsuit against Nissan for putting faulty transmission on Altimas 2015.”

“The contact owns a 2015 Nissan Altima. The contact stated that the check engine warning light was illuminated, and the vehicle failed to accelerate from a complete stop and jerked. Additionally, the vehicle failed to respond as intended while in reverse(R). The vehicle was taken to the local mechanic who diagnosed the vehicle and determined that the transmission was faulty and needed to be replaced. The vehicle was not repaired. The vehicle was later taken to the local dealer, where a diagnostic test was performed on the vehicle, and it was confirmed that the transmission was faulty and needed to be replaced. The vehicle was not yet repaired. The manufacturer was not contacted. The failure mileage was 68,000.”

“Car began shuddering when trying to accelerate. Car periodically will stop running or not start. No dash lights came on until recently when car would not start the battery nd engine light came on This all started end of September. Has been diagnosed by Nissan Dealership with 2nd diagnosis by an automotive shop close to my home. Informed this is a known issue with this make and model. Researched online and found this the be true. I received no notification. Both came up with transmission and CVT internal problem. Safety hazard for car to die in traffic. I have cancer and heart failure which makes general mobility an issue. I can’t quickly exit the car nd get out of the way of traffic. Informed only the dealership can address the issue. Quoted $6700 to repair/replace”
