2018 Nissan Altima engine 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.

1- el motor esta partido 2- foco trasero derecho las conexiones están malas y los cables podridos. 3-el carro dejo de acelerar en carretera perdiendo totalmente el control. 4- lo lleve a un mecanico y el diagnostico fue que el motor esta partido porque al carro nunca le hicieron sus mantenciones ni cambios de aceite y esto deterioro el motor. 5- el banco no y el dealer me dice que todo lo que le pase al carro luego de su compra no tiene nada que ver con ellos. 6- el carro lo compre y tenia varias lamparas encendidas pero en el dealer me dijeron que estaban fallando los censores pero que todo estaba bien. Lo que era todo mentira. El dealer cuando compre el carro me dijo que tenia garantia por 6 meses, como no hablo ingles ellos me explicaron las condiciones del contrato y firme un papel sin saber que era que no tenia garantia, y cuando compre el auto venia con fallas pero ellos mismo la revisaron y dijeron que era solo una goma. Luego de esto empieza con mas fallas pero descubro que el dealer lo cerraron y no contestan los llamados para reclamos ni nada.

The problem of delayed acceleration. The problem occurs when the vehicle does not seem to accelerate for a short period of time. When I'm at a stop. and I depresses the pedal. The vehicle does not rev. It does not do anything for a few seconds. Even with increased force on the pedal, the vehicle does not move. The second concern is that, once it does move, it does so significantly with a jolt. This means that, after a few seconds of not functioning, the vehicle will suddenly accelerate quickly. This can create an increased risk of an accident.
