Most reported Cadillac problems
A burning smell may develop due to an oil leak form one or both valve cover gaskets. Resealing the valve cover will generally correct this concern. However, the valve covers should be inspected and replaced if damaged.
An engine vacuum leak may develop from the throttle body gasket causing a higher than normal idle speed. Failed gaskets should be replaced.
A common source of oil leaks is from the rubber transmission cooler lines. The fluid will often be red in color.
The trunk pull down switch may fail causing the trunk lid not to close completely. Our technicians tell us that the failed switch can be replaced without changing the complete pull down motor assembly.
The front struts may show signs of wear, or be excessively bouncy ride at freeway speeds. This may begin to occur at around 75,000 miles.
The engine may develop a misfire due to worn valve seats. This fault will cause the Check Engine Light to illuminate. Our technicians tell us the misfire may or may not be felt while driving. They further recommend that both cylinder heads be removed and thoroughly inspected and repaired as necessary.
The inside door handles are prone to breaking.
The steering wheel position sensor may fail, resulting in the service stability message being displayed.

If the valve body is worn, replacement will be necessary to correct this concern.
A/C condenser cracked in 4 places. Have to replace as well as well as the on/off switch stopped working.
