Cadillac STS Repair and Maintenance

A guide to problems, costs, maintenance and repair for your Cadillac STS

The front turn signal and and daytime running light bulbs are prone to premature failure. Our technicians tell us that these bulbs can be very difficult to replace.

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.

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. Our technicians tell us that some vehicles may require a powertrain control module (PCM) software update to correct this issue. 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.

Great car. Drives and handles perfectly. Only complaint....Almost .No storage spaces.

Stay on top of the maintenance. Don't treat it like a comaro when its a Cadillac. Don't complain about the small things.. Can't speak for the other sts owners, but mine is fun to drive and looks "saf" (black on mat black) :) peace.
