NHTSA complaint #11631058, filed 2024-12, 700 miles“On 4/14 with only 21 miles on the odometer in this newly purchased car the entire transmission failed, per the dealership because of a “leaking valve”. The check engine light came on after the car was jumpy and then the car refused to speed up on an extremely busy street and began locking up, putting us at serious risk of an accident. It was barely able to reach a parking lot and at that point all of the transmission fluid leaked out all over the parking lot.”
