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.

Car runs rough at idle and has difficulty accelerating. Check engine lights comes on intermittently. CODE p0101 points at MAF sensor. Replaced multiple times. Cleaned air system, ie filter, hoses and throttle body. Same issues. Car feels unpredictable and unsafe. Can’t accelerate through intersections and does not respond well went issue is present.

I am writing to formally report ongoing and unresolved issues with my vehicle that have significantly impacted its safety and reliability. The persistent problems include: Multiple simultaneous dashboard warning indicator illuminations Recurring "See Owner's Manual" malfunction notifications Intermittent Key System Error messages Continuous presence of diagnostic Code P0101 A representative from the dealership management informed me that Code P0101 is a known and widespread issue affecting multiple Nissan models, including the Versa, Sentra, and Altima. Despite this acknowledgment, I have been repeatedly told that these concerns are "under engineering review," yet no progress has been made, nor have I received any meaningful updates regarding the investigation. This lack of resolution raises serious safety concerns, and I urge the NHTSA to investigate this matter further. I appreciate your attention to this issue and any guidance you can provide on the next steps to ensure the safety and functionality of my vehicle. Sincerely,

I am writing to report a potential safety and design defect in my vehicle that I have also noticed affecting many other owners of the same make and model. The issue involves the rubber seal at the edge of the windshield, which is supposed to prevent water from entering the engine bay. However, the rubber is not properly secured—it merely sits in place—allowing water to pass underneath it. As a result, water accumulates on the valve cover near the ignition coil, creating a risk of electrical problems, including misfires or potential engine failure. Over time, this could lead to serious mechanical and safety issues. After researching, I have found that many other owners of the same vehicle have experienced this same problem. I believe this issue poses a safety concern and should be investigated further. Please advise on any next steps or potential recalls regarding this matter. Thank you for your time and attention.

Safety is at risk for multiple reasons one because a month upon receiving this brand new vehicle with 40 miles on it I’ve been experiencing malfunctioning problems. I am not able to receive a forward collision warning at times. I’m not sure if these electrical problems also caused my battery to die a few weeks later. In these moments is the start of when the malfunction notification would appear daily. Two— The transmission has been having issues for a long time as well. My drives no longer have a smooth transition when I press the gas it stutters and will not accelerate immediately. The problem has been confirmed by an independent service center. I brought my car new once again so am very disappointed at how much needs to be worked on and do not want to purchase from Nissan ever again.

Everytime I turn my car on, there’s a chance that some lights will turn on my dash for absolutely no reason..the car could be parked and getting warmed up and the traction control light,parking collision warning, and front collision light all turn on simultaneously. I have included a photo to get a Better picture! only way for me to get rid of them is by turning my car off for 5 minutes then turning it back on again. It been a real inconvenience. Not to mention when those lights turn on it means I can’t Parallel park anywhere because my rear parking assist prevents me from backing up, because it “thinks” something is in the way…ugh! Not only that but everytime I play music my Nissan Connect shuts of in the middle of my drive then resets and starts playing music again. If you guys have any answers for me please let me know I bought this car in August of 2021
