What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 1998 Cadillac Sts, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

Each component in detail
What the reports in each category say, in the owners' own words
Airbags
Reports naming the air-bag system — deployment behaviour, inflators, sensors and warning lights.
From owner reports, verbatim
THE MAIN AIR BAG FROM THE STEERING WHEEL WAS SET OFF WITH THE CAR RUNNING AND IN PARK. THE CAR WAS NOT MOVING NOR WAS THERE ANY COLLISION TO SET OFF THE AIR BAG. LATER INVESTIGATION BY CADILLAC/GM DETERMINED FAULTY SENSORS THAT CAUSED THE AIR BAG TO DEPLOY IMPROPERLY WHICH CREATED/CREATES A POTENTIALLY DANGEROUS SITUATION.

AFTER A POLICE STOP FOR HIGH-MOUNT BRAKE LIGHT INOPERATIVE, I LEARNED THAT THERE IS A 100% FAILURE RATE FOR THIS 3RD BRAKE LIGHT IN CADILLAC VEHICLES. MINE IS A 1998 STS, NOW WITH 80K MILES. IT IS NOT SIMPLY A BULB REPLACEMENT BECAUSE IT IS A SEALED LED UNIT AND IT IS VERY EXPENSIVE. THE UNIT IS SUBJECT TO WATER DAMAGE. THE PRICE FOR THE PART ALONE IS OVER $800. RESEARCH HAS REVEALED THAT THIS PROBLEM WAS FIRST NOTED ON 1992 - 1997 VEHICLES, AND THEN AGAIN ON 1998 - 2001 CADILLAC VEHICLES WITH 100% FAILURE RATE, NO REPAIR IS POSSIBLE OTHER THAN REPLACING THE $800 PART. THE CADILLAC DIVISION OF GM SHOULD STAND BEHIND THEIR PRODUCT AND REPLACE THESE DEFECTIVE UNITS. *TR

Steering
Reports naming the steering system — racks, columns, power-steering assist and steering linkage.
From owner reports, verbatim
DAUGHTER WAS DRIVING VEHICLE. ON TWO SEPARATE OCCASIONS (THANKFULLY BOTH AT SLOW SPEEDS) STEERING WHEEL LOCKED UP AND COULD NOT BE TURNED (LOCKED UP HEADING LEFT). SHE WAS ABLE TO GUIDE VEHICLE TO STOP WITHOUT INJURY. SHE TURNED OFF VEHICLE AND RESTARTED AND STEERING RETURNED TO NORMAL. ONLINE RESEARCH INDICATES ALL CADILLAC MODELS OF THIS VINTAGE AND SOME NEWER ARE EXPERIENCING THIS STEERING PROBLEM. HOWEVER, NO RECALL OR SERVICE BULLETINS ISSUED. THIS IS THE LAST GM PRODUCT WE WILL EVER PURCHASE. *TR

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
