Rear air-shock compressor malfunction. Out of nowhere the rear of my car was higher than normal and after finally getting the dealership to check it they told me that the compressor was jammed and needed to be replaced. This car has been experiencing random malfunctions and breakdowns in various systems since it was purchased and I'm forced to pay out-of-pocket due to the poor design and quality of this car. The individuals at the dealership just shrug it off and say that it happens but regular breakdowns in random parts of a car do not "just happen".
