2008 Cadillac STS Problems
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.
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.
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.

V8 STS Amazing car, best car we ever had. We have owned Mercades BMW's Audi's. We also owne a 2009 Mercades E430 V8 the Mercades is a sharp car but the Caddy wins hands down it has smooth power and shifts so smooth and rides and handles better the the E430. The STS is the best car we have had by far.
