While driving the engine stalls. It has jolted back-and-forth at times and had to be taken to a dealer. It’s still stalls when trying to slowly accelerate especially uphills. Low gas mileage barely getting 18 miles per gallon. Warning lights flickering while car stallling. It’s like it’s having a seizure. This has happened a few times.
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).
