Engine - slows down and speed up and jolt as it accelerate in speed. Heated seats - a month after purchase they stopped worked oil pump - the filter gets clogged with metal shaving and would not allow the oil to get to the engine. As a result, I had to get oil changes 3 times in a month. Dash board and stereo light would flicker and dim. Stereo would repeat words and get stuck in one place. The wind shield wipers stopped working during a rain storm and were wiping in two separate directions at the same time.
