Brand new car Engine light also went on and off 3 or more times in one day, car had a charging failure wouldn't charge - Sold me an unsafe vehicle to drive - shaking tires, steering wheel, Car also has 13 codes including engine and transmission failure communication codes - multiple attempts to resolve the matter and the service team wanted me to sign a release of liability and were refusing to change the tires or make the vehicle safe. took the car to a 3rd party to get an accurate assessment - also for the record this was the second unsafe car they sold me the first car needed new axles and apparently was in the service line and someone closed the tickets out and i was sold a different vehicle.
