1995 Isuzu Trooper

1(A). AFTER DRIVING AT HIGHWAY SPEEDS (ABOVE 60 MPH) THE ABS WARNING LIGHT ON THE INSTRUMENT PANEL NEARLY ALWAYS COMES ON. THIS HAS OCURRED HUNDREDS OF TIMES. 1(B). WHEN DRIVING IN SLIPPERY SNOWY CONDITIONS, AFTER APPLYING THE BRAKES THE ABS COMPUTER MAKES A LOUD BUZZING NOISE THAT WILL NOT STOP UNTIL THE ELECTRICAL CONNECTION TO THE 4 WHEEL DRIVE ABS COMPONENT IS SEVERED BY EITHER REMOVING THE NEGATIVE BATTERY CABLE FROM THE BATTERY OR REMOVING THE FUSE. THIS HAS OCURRED MANY TIMES, BUT ONLY THREE TIMES HAS IT CAUSED A LOSS OF CONTROL WHERE PEOPLE WERE AT RISK OF HARM. 2. UNDER THE BUZZING CONDITION NOTED IN 1(B) ABOVE, THE ABS BRAKING SYSTEM SEEMS TO FAIL, WITH LESS CONTROL BECAUSE THE BRAKES LOCK UP, AND STEERING BECOMES IMPOSSIBLE. AT LEAST THREE INCIDENTS HAVE HAPPENED WHERE THE VEHICLE RAN INTO THE CURB WITH NO APPARANT DAMAGE, GREATFULLY NO OTHER VEHICLES OR PERSONS WERE INVOLVED. EACH INCIDENT 1(B) HAS HAPPENED ON WEEKENDS OR AT NIGHT AFTER THE DEALER WHO SERVICES THE VEHICLE IS CLOSED. 3. THE DEALER HAS FOUND NO PROBLEMS, STATING WE MUST BRING IN THE VEHICLE WITH THE LIGHT ON OR THE BUZZING OCCURRING IN ORDER TO LOCATE A PROBLEM. I BELIVE THERE HAVE BEEN RECALLS ON OTHER ISUZU MODELS FOR THE SAME PROBLEM, BUT NOT FOR THE MODEL OR YEAR OF OUR VEHICLE.

IMMEDIATLY AFTER PURCHASING THE TROOPER IN 1995 WE NOTICED WE HAD TO STAND ON THE BRAKES TO STOP WHEN GOING DOWN THE DRIVEWAY. AFTER REPEATED TRIPS AND COMPLAINTS TO COCHRAN PONTIAC IN MONROEVILLE, WE WERE TOLD EACH TIME THERE WAS NOTHING WRONG. THEY FINALLY REPLACED THE BRAKE VACUUM BOOSTER HOSE IN 4/97 AND AGAIN IN 6/97. THIS HELPED MINIMALLY. WE TOOK THE CAR TO BE INSPECTED 6/99 AND HAD TO REPLACE THE ENTIRE BRAKE SYSTEM AT ONLY 34200 MILES. WE WERE TOLD BY THE MECHANICS AT THIS INDEPENDENT SERVICE STATION THAT THE CONDITION OF THE BRAKES WERE UNSAFE AND THE SYSTEM DID NOT APPEAR TO BE ENOUGH FOR A CAR OF THIS SIZE. ISUZU'S INDIFFERENCE TO OUR PROBLEM HAS PROMPTED THIS COMPLAINT.
