July 2021, While my son and daughter were driving the car engine shut off, the brakes, the gas pedal and steering wheel locked. The vehicle was on a slight incline and rolled backwards. My son quickly pulled the emergency brake in order to stop the vehicle from going into the vehicle behind him. The vehicle was restarted and all the problems were gone. We brought the vehicle to the dealer. They checked and found nothing wrong and could not recreate the problem. At the same time the dealer performed the recall 21V259 (letter dated 6/11/2021) which was rectified by performing an engine vibration inspection which passed. At that time we also reported a ticking sound coming from the engine which the dealer stated is a normal noise from the injectors. A NY state inspection was also performed and passed.
