NHTSA complaint #10173980, filed 2006-11, 48,000 miles“I have a 2001 Cadillac dts the engine take excessive amounts of oil and a coolant absorption that cause overheating and constant engine work. I was told at the Cadillac dealership this is a common problem with the Cadillac north star engine. The engine shuts offs when the car runs hot and my safety was in jeopardy due to this known failure. Gm should fix these known safety issues with cars with this issue at no cost to the customer. These issues normally range from $1000-$4000 to repair.”

NHTSA complaint #10380163, filed 2011-02, 140,000 miles“2001 Deville car dies when ever it wants for no reason. Why has there been no recalls for this engine that is on many years. Sensors replacing does no good and the fuel filter change and fuel pump does no good. And replacing the battery does no good. It is the engine and no one has a cure. When someone gets killed maybe there will be a recall then.”
