This car had been horrible! Bought it used from a dealer and bought the extended warranty, that was lucky as the knocking and the leaking head gasket wrecked the engine. The insurance paid for its replacement. Then the second engine started doing the same thing! It made a loud knocking sound that "GM does not consider it a problem." Then it overheated and the mechanic did not think it is worth replacing this engine. So the car is junk. We have had the gas door rusting issue and the ignition switch not working issue,the and the turn signals not working issue too. The interior is cheap and we had to replace two speakers that failed. The fan motor does not work in the low speed settings
The tires seem to wear out fast too.
I would not buy from GM again until I see that they will stand behind their products! This car never should have left the factory! Make sure to buy an extended warranty!
