Contact states they were sitting in DRIVE, with their foot on the brake. When the contact took their foot off the brake, they began to let the vehicle coast to about 5 MPH. Then, the vehicle lunged forward unexpectedly to about 25 MPH, when it collided with a rock. The vehicle had previously spent over 10 days in different dealerships to diagnose issues related to the engine running rough, the car stalling out, and the vehicle driving erratically and lunging forward. The contact only began to have issues with the vehicle after the NHTSA Denso Fuel Pump Recall. A year after the contact took delivery of the vehicle, the remedy was done. The dealership stated they had completed the remedy properly, but because of parts shortages they only MODIFIED the fuel pump, but that TMNA said this is a valid remedy. After further investigation, the remedy protocol which they followed did not match the one the manufacturer assured NHTSA they would follow, and there was no amended NHTSA remedy. Then, the manufacturer denied they told the dealership that the protocol they followed was a valid remedy. About 10 minutes after leaving the dealership the contact returned and stated the vehicle was running rough and driving erratically. The dealership told the contact that it was completely normal and that the vehicle just needs to re-learn their driving style. The contact had issues with the vehicle, including the illumination of warning lights, and the dealership cannot remedy the issue (refusing to replace/repair the fuel pump).

The contact owned a 2020 Lexus RX350. The contact stated that while making a left turn into a parking lot at approximately 10 MPH, the vehicle suddenly accelerated on its own and crashed into the side of a Walmart shopping store. The air bags deployed upon impact. The contact and her sister were both taken by ambulance to two separate hospitals. The contact was treated for fractures to her right hand and wrist; screws were placed in her right wrist and another was placed in between her index and middle right finger. The contact had additional X-rays performed on the right of her body where she experienced pain and soreness to the right side of her back and leg; as well as her breastplate. The contact's sister was treated for a fractured hip, spine, and breastplate. Both the contact and her sister attend physical therapy to treat their injuries. A police report was filed. The contact was uncertain if any property damage was caused by the accident. The vehicle was towed to an independent mechanic where it was deemed a total loss. The manufacturer was notified of the failure and an independent investigator was sent to investigate the failure; the cause of the failure had yet to be determined. The vehicle was destroyed due to the accident. The failure mileage was approximately 17,000.
