This has been ( fixed) twice, and its doing it again. Quite expensive to fix. So much for good Greman engineering....
Oil spot under car. Leak repaired at dealership.
also, check engine light is on with codes OBD (P0170, P0130, P0110 )
Kept having O2 sensor problems, went to dealer and they informed of the problem. They recommended replacing the cam sensor and trying to flush the wiring to the O2 sensor connector with solvent.
