2021 Nissan Murano

While accelerating to merge into traffic and make a left turn, the vehicle briefly hesitated, which has occurred previously. After completing the turn and straightening the vehicle, I fully released the accelerator pedal, but the vehicle continued accelerating and maintaining speed without accelerator input from me. The vehicle appeared to maintain approximately 54 mph in a 45-mph zone while I was not pressing the accelerator pedal. I applied the brakes, but the vehicle did not immediately decelerate. To regain control, I shifted the transmission into Neutral. Once the transmission was in Neutral, the engine RPM increased briefly and then quickly returned to normal, and I was able to slow down and stop safely. This occurred at approximately 6:00 PM on Saturday, June 20, 2026. There was no floor mat or anything else blocking or touching the accelerator pedal. After I stopped, the vehicle seemed to drive normally again. The vehicle has also had a recurring condition after startup in which the engine sometimes revs higher than normal for a short time before returning to a normal idle. I am including this as an additional observation. The continued acceleration after I had fully released the accelerator pedal created a safety concern. I am submitting this report so the incident can be documented and investigated.

I am reporting a safety concern involving a 2021 Nissan Murano Platinum with approximately 45,000 miles. The vehicle experienced water intrusion into the cabin due to a failure in the panoramic sunroof drainage system. A Nissan dealership diagnosed that water was leaking from the sunroof channels and that the drain hoses were contaminated and not functioning properly. As a result, water entered the interior of the vehicle, soaking the A-pillars and floorboards. There was also a musty odor, indicating that moisture remained trapped inside the vehicle for a period of time. In addition to the interior water intrusion, the dealership found corrosion in an electrical connector related to the power liftgate system and moisture inside the headlight assembly, causing lighting failure. I am concerned that water intrusion into the cabin and pillar areas could affect electrical systems, wiring, and safety-related components, including those located near the A-pillars. This issue occurred at relatively low mileage and appears to be more than normal wear and tear. The combination of water intrusion and electrical component damage raises concerns about long-term reliability and potential safety risks. I am reporting this so the issue can be documented and reviewed for potential broader impact.
