1990 CADILLAC Allante Problems & Complaints

POWER ASSIST BRAKE FAILURE. BRAKES ARE OPERATING AT 10 PER CENT BY PUMPING TO A GRADUAL STOP. DOWN-SHIFTING AND PANIC PUMPING AVOIDED A CRASH. *TR

WITHOUT WARNING, BRAKES ON MY 1990 CADILLAC ALLANTE FAILED AND I RAN INTO A TRUCK AT A TRAFFIC LIGHT. *TR

WHILE ATTEMPTING TO APPLY THE BRAKES THEY FAILED COMPLETELY, TOOK VEHICLE TO DEALER, AND MECHANIC STATED MASTER CYLINDER WAS LEAKING INTERNALLY WHICH CAUSED TOTAL BRAKE FAILURE. *AK *PH

NO SUMMARY LISTED FOR THIS VEHICLE. *AK

WHILE DRVING, ANTI LOCK BRAKE SYSTEM FAILED. POWER WENT OUT, AND HAD TO APPLY BRAKES MANUALLY TO STOP VEHICLE. *AK CONSUMER STATES UNABLE TO GET PARTS TO REPAIR. *TT

FAILURE STARTED WITH: ABS/TRACTION CONTROL FAIL LIGHTS AND READ-OUT ON THE DIC & HVAC PANEL ALONG WITH BRAKE PEDDLE 'THUMP' (NORMAL). THIN FINAL LOSS OF ALL BRAKEING DUE TO ACCUMULATOR AND HI-PRESS PUMP LOSS.CODE 63 WAS NOTICED BUT WAS UNABLE TO ISOLATE.

ANTILOCK BRAKES REQUIRE REPAIR...CAR STILL HAS STOPPING POWER BUT NO ANTILOCK AT TIMES

ABS FAILURE COMMON TO CADILLAC ALLANTES WITH BOSCH ABS SYSTEMS

EXPERIENCED TEARING OF THE CONVERTIBLE TOP AT THE SAME TWO POINTS ON THE REAR OF THE CAR. CONSUMER CLAIMS ALL ALLANTES EXPERIENCE SIMILAR PROBLEM. *AK

THE DRIVER'S SIDE DOOR UNLATCHES WITHOUT DRIVER'S EFFORT. THE VEHICLE HAS BEEN TO THE DEALER 4 TIMES, DEALER DETERMINED THAT THE HINGES NEED REPLACEMENT. *AK

OVER THE LAST MONTH, WHILE BRAKING THE DRIVER INFO DISPLAY WOULD SHOW ANTILOCK-TRACTION DISABLED, THEN WOULD FLASH ANTILOCK OK, TRACTION OK. VEHICLE SEEMED TO BRAKE JUST FINE AND SINCE THE DISPLAY SAID IT WAS OK I DIDN'T THINK IT WAS A PROBLEM, THEN ON 9/20/2014 WHILE DRIVING HOME DOWN MY STREET THE CAR WOULD NOT STOP AND THE RED BRAKE LIGHT CAME ON THE DASH. THIS HAPPENED ALL WITHOUT WARNING. THE LAST TIME THE BRAKES WERE APPLIED IT SHOWED NO SIGNS OF TROUBLE. FROM WHAT I HEAR THIS IS A VERY COMMON PROBLEM FOR CADILLAC ALLANTE FROM 87-92. I KNOW THAT THERE WERE NOT MANY OF THESE CARS MADE (ABOUT 3000 PER YEAR) BUT IF THIS IS A COMMON PROBLEM THEN I FEEL THIS MUST BE ADDRESSED, SINCE IT IS SAFETY RELATED. MY GRANDSON IS GETTING HIS DRIVER'S LICENSE THE FIRST OF THE YEAR AND I WAS GOING TO GIVE HIM THIS VEHICLE...NOW I HAVE SECOND THOUGHTS..I CAN'T BELIEVE GM WOULD ALLOW SUCH A VEHICLE TO BE ON THE HIGHWAYS. THIS A VERY DANGEROUS SITUATION!!! THANK YOU FOR YOUR TIME *TR

I RECIEVED AN ANTILOCK DISABLED MESSAGE AND WITHIN 1 MILE THE BRAKES TOTALLY FAILED. THE CAR STILL HAD GOOD BRAKE PEDAL, BUT NO BRAKES AT ALL. THE EMERGENCY BRAKES FAILED AS WELL. FORTUNATELY, IT WAS 3:30 AM AND NO TRAFFIC. I WAS ABLE TO SWING INTO AN EMPTY PARKING LOT AND CIRCLE UNTIL THE CAR CAME TO A STOP. UPON TALKING TO SEVERAL OTHER ALLANTE OWNERS, I FOUND OUT THAT THIS IS A FREQUENT OCCURANCE WITH THESE CARS. DOES SOMEONE HAVE TO BE KILLED BEFORE CADILLAC DOES SOMETHING ABOUT THIS POTIENTIALLY FATAL FLAW?*AK

EVER SINCE I PURCHASED THIS VEHICLE EVERY TIME I STEP ON THE BRAKES I RECEIVE A MOMENTARY DROP IN THE BRAKE PEDAL, WHAT APPEARS TO BE A LOUD CLICKING COMING FROM UNDER THE DASH AREA AND THEN A REFIRMING OF THE BRAKE PEDAL JUST BEFORE COMING TO A STOP. ALL THE TIME THIS IS HAPPENING I AM RECEIVING A MESSAGE ON THE DRIVER INFORMATION CENTER, ANTI-LOCK DISABLED, TRACTION CONTROL DISABLED FOLLOWED BY ANTI-LOCK O.K., TRACTION CONTROL O.K. I DO NOT FEEL SAFE IN THIS VEHICLE AND SINCE I PURCHASED THIS VEHICLE I HAVE TALKED TO OTHERS WITH THE SAME OR SIMILAR PROBLEMS AND I DO NOT FEEL THIS IS AN ISOLATED INCIDENT. I FEEL THERE IS A DEFECT IN THE MANUFACTURING OF THE BRAKE SYSTEM COMPONENTS AND SHOULD BE REPAIRED BY THE MANUFACTURER REGARDLESS OF MILEAGE OR WARRANTY TIME.
