When driving the whole car shakes and the engine makes a loud sound. It doesn't matter if I am going 10 mph or 75 mph the same shaking happens. The engine smells like burnt rubber. Driving feels like jerking not a smooth ride. I have already had the engine oil leak repaired. My car has been in the shop 3x in 2 months for this same problem. The dealership did a transmission systems update which did not help. When driving downhills the RMPS shoot up and get stuck between 3,000-4,000. The dealership could not find any documentation that downhill assist is a feature on this car. The dealership was not able to replicate these issues.
