NHTSA Complaint #11697255 — 2020 NISSAN VERSA

I am reporting a chronic and dangerous defect in my 2020 Nissan Versa that results in an unpredictable, sudden, and complete loss of acceleration (motive power) while driving. This defect has been present since shortly after purchase and remains unresolved, posing a severe safety risk on public roads. Specific Safety Incident Details: Symptoms: The failure begins with the illumination of the Malfunction Indicator Lamp (Check Engine Light), simultaneously accompanied by dashboard messages like "Malfunction See Owner’s Manual" and "Key System Error." The Critical Safety Hazard (Loss of Power): Immediately following the dash warning, the vehicle experiences a major, sudden loss of acceleration. This is not a gradual deceleration—the throttle becomes unresponsive, and the vehicle will not accelerate for approximately 4 to 5 seconds. Driving Conditions: This failure occurs randomly, including during critical maneuvers such as accelerating from a stop, merging into traffic, or attempting to accelerate on a highway. Consequence: When the vehicle unexpectedly fails to accelerate (especially in high-speed or high-traffic situations), it creates a high risk of being struck from behind or being unable to clear an intersection or merging lane safely. Initial Report (In-Warranty): The problem was first reported on March 31, 2021 (Mileage 25,404) to Central Houston Nissan (Invoice # NICS309560) and again on July 29, 2021 (Mileage 32,229) to Sterling McCall Nissan (Invoice # 2373806). Engineering Investigation: On both occasions, the dealerships specifically noted that the issue (DTC P0101 and associated warnings/power loss) was "under investigation under Nissan Engineers." Technical Service Bulletin (TSB): Nissan has acknowledged this widespread issue by releasing TSB NTB21-049 (June 8, 2021), which addresses the "MIL ON WITH DTC P0101" for the 2020-2021 Versa model.
