2018 Nissan Altima: hesitation when accelerating

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.

A lag when accelerating from a stop. Step on the accelerator and feel a slight clunk before I start to move. Turning off overdrive seems to give a more solid start with not so much hesitation. Always feel like I need to gently accelerate from stop or something might break
