My CTS is under warranty and have only been driven 20.000 km - the first serviceinspektion was only 1 month ago - today the engine light came on - My OBD scanner showed 2 faults: two times P0009 Engine Positions System Performance Bank 2.

I deleted the errors and the enigine started up with no engine light - should I hurry to the dealer tomorrow, or can I wait "untill next time":confused:

may be one of the timing chain CEL issues. Typically, in these cases there is no urgency to rush in to the dealer. If it is due to timing chain the most recent GM bulletin will have them adjust the sensor so it doesn't throw the check engine light and change the oil life sensor to recommend more frequent oil changes.
