About Cadillac STS

Could be traced all the way back to the special range-topping 1950s Serville hardtop, Cadillac STS was produced by an American multinational corporation General Motors Company's Cadillac Motor Car Division from 2004 to 2011 as a mid-size luxury sedan for the United States market. Originally introduced as the replacement for Cadillac Serville, STS became Cadillac's highest-priced sedan, slotting between the mid-size CTS and full-size DTS in size. "STS" in its name means "Serville Touring Sedan". After being manufactured for two generations, Cadillac STS was still eventually replaced by the third-generation Cadillac CTS and Cadillac XTS.
The first-generation Cadillac STS was produced from 2004 to 2007 as a 4-door notchback sedan at the GM Sigma platform. Except for the similar SLS edition, it only came in one single trim level. During this generation, STS was powered by a 3.6 L V6 rated at 255 hp and 252 lb-ft of torque and a 4.6 L V8 producing 320 horsepower and 315 pound-feet of torque and engines sent power through 5-speed or 6-speed automatic transmission to all wheels. Then the STS was updated for the 2008 model year. Then it came in with trim levels including Luxury Sport, Luxury, Premium and Performance. The 3.6 L V6 engine was retained but then it could produce 302 horsepower while the 4.6 L V8 engine was still with an output of 320 hp. But both engines sent power through a 6-speed automatic transmission to the rear wheels.

Cadillac STS Common Problems & Maintenance Tips

Boasting surprisingly agility, respectable performance and a high-quality audio system, Cadillac STS is a good idea for a luxury sedan with competitive amounts of power, roominess, comfort and valve. But you still have to be prepared all the time for these common problems that may arise on STS:
First, issues on suspension, steering and transmission are very awkward for Cadillac STS drivers as they not only bring an uncomfortable, unsteady and unsmooth driving experience, driving dangers may be also lament. The similarity between these issues lies on the odd sounds from beneath the vehicle. But suspension failure often also causes intense car vibration, uneven tire wear and poor handling and the STS control arm bracket, trailing arm bushing, and sway bar link are often the reasons. As for steering failure, if you feel the steering wheel is stiff and find damages on the belt, then the STS power steering pump needs replacement. And the wrong gear and not moving shift indicator are warning you that the STS automatic transmission shifter is broken.
Second, engine and braking failures could be regarded as two most serious issues that Cadillac STS could have ever met during driving. Engine problem is needless to explain as it often results in the breaking down of the vehicle directly. In STS, some drivers complained that the engine will stay at a very poor or high idle and performance reduces dramatically. And they find the problems often lie on the STS throttle body and throttle body gasket. As for braking failure, it often manifests as leaking brake fluid and lit Brake Warning Light, which brings the suspicion to the STS brake line and hydraulic hose.
But for a qualified and responsive Cadillac STS drivers, routine maintenance is the way to stay away from any unexpected fatal car accidents and enjoy a safe and comfortable driving trip. After all, some auto parts of the vehicle are bound to wear and tear quickly than others due to different constituent materials and working conditions. Seat belt, for example, is often made of resilient nylon but undertakes the responsibility of protecting occupants against harm brought during a collision and sudden movement. Besides the seat belt, windshield wiper, wiper blade, hood latch, hood cable, emblem and battery cable also should be maintained on a regular basis.
