2011 Cadillac STS common problems

The most-reported problem areas from 7 owner complaints filed with NHTSA — and what to check before you buy.

Electrical System

Test every electrical feature: windows, locks, infotainment, charging and all lights. Watch for flickering, dead accessories or warning lights.

Service Brakes

Brakes should feel firm and quiet — no grinding, pulsing or pulling. Check for an ABS light and uneven pad/rotor wear.

Steering

Steering should be tight and centered — no play, clunks or wandering. Test at low and highway speed; listen for power-steering whine.

Vehicle Speed Control

Test cruise control and throttle response, and watch for any hesitation or unintended acceleration.

Exterior Lighting

Confirm all headlights, brake lights, turn signals and reverse lights work, with no moisture inside the housings.

Seat Belts

Check that every belt latches, retracts and locks under a sharp tug, and that none are frayed.
