NHTSA Complaint #736098 — 1987 CADILLAC ALLANTE

I HAVE COMMUNICATED WITH OTHER ALLANTE OWNERS WHO HAVE REPORTED BRAKE FAILURES WITH THE BOSCH III ABS SYSTEM INSTALLED ON THESE CARS. THIS FAILURE IS CATASTROPHIC BECAUSE THE EMERGENCY BRAKE SYSTEM REQUIRES AT LEAST 3 1/2 PUMPS OF THE ACTUATOR, BUT CANNOT BE ENGAGED WITH THE CAR IN GEAR. ALTHOUGH THE DRIVER INFORMATION CENTER WILL WARN OF COMPONENT PROBLEMS WITH THE SYSTEM USING A SERIES OF COMPLICATED CODES, IT IMPLIES THAT THAT ABS SYSTEM CAN BE DEACTIVATED AND THE BRAKES WILL STILL FUNCTION. THAT MAY BE CORRECT OR MAY NOT. IN SOME CASES, PEOPLE HAVE DRIVEN FOR A YEAR WITH THESE WARNINGS APPEARING INTERMITTENTLY, ONLY TO HAVE COMPLETE FAILURE OCCUR WITHOUT WARNING. IN OTHERS, THE BRAKES FAILED ALMOST AS SOON AS THE WARNINGS APPEARED. WORSE YET, THE WARNINGS SEEM TO IMPLY THAT THE BRAKES WILL FUNCTION WITH THE "ABS SYSTEM DISABLED". IN SOME CASES THEY DO, BUT COMPLETE AND CATASTROPHIC FAILURE WILL OCCUR AT SOME COMPLETELY UNPREDICTABLE TIME IN THE FUTURE. THIS CIRCUMSTANCE IS ABSOLUTELY INTOLERABLE AND CONSTITUTES A MAJOR SAFETY THREAT TO THE OWNER AND THE PUBLIC. THE COST OF REPAIRING THIS SYSTEM WILL RUN FROM $1500-4000, AND NEITHER CADILLAC NOR BOSCH HAS MADE ANY EFFORT TO "PATCH" OR UPDATE THE DESIGN, PROVIDE A MORE FAILSAFE SYSTEM, OR SUBSIDIZE IN ANY WAY THE COST OF THESE REPAIRS. I AM AWARE OF NO OTHER CAR WHOSE ESSENTIAL BRAKING SYSTEM WILL REQUIRE THOUSANDS TO MAINTAIN OR ABSOLUTELY WILL EITHER COST THOUSANDS THAVE COMPLETE BRAKE FAILURE WILL SUFFER CATASTROPHIC FAILURE WITHIN 140,000 MILES. *AK
