Cadillac CTS Problems

The Check Engine Light With Code: P0011, P0014, P0021, P0024, P0341, P0346, P0336, and/or P0391

Vehicles with certain V6 engines may illuminate the Check Engine Light one or more of the following codes: P0011, P0014, P0021, P0024, P0341, P0346, P0336, or P0391.

Other vehicles may have excess camshaft end play on one or both cylinder heads which will need to be corrected using special procedures outlined by GM.

Rear Axle Pinion Seal May Leak

The rear axle pinion seal may leak causing fluid loss and possible internal rear end damage. Replacing the faulty seal will commonly correct this concern. Some 2005-2007 models have been recalled for this issue.

Cadillac CTS Reviews

2011 CTS with 29,000 miles. Steering wheel was loose, lots of play. They had to replace the control arm. Got the car back and steering wheel is cocked about 8 degrees to the right, not dead on center. Brought it back multiple times. Finally they had to replace the entire steering rack. Should not happen on a car with 29K miles
