THE FIRST ECU WENT WHEN I WAS SITTING IN MY DRIVEWAY THE RPMS WERE ERRATIC I GOT IT FIXED, ORDERED A NEW ECU COST ME $950. IT LASTED NO MORE THAN 3 MONTHS AND THE SAME PROBLEM DEVELOPED ON THE NEW ONE. I DO NOT WANT TO KEEP SPENDING ALMOST $1000 EVERY THREE MONTHS. I ALSO DON'T WANT TO SELL THE CAR AND HAVE THE NEW OWNER HAVE THE SAME PROBLEMS. I HAVE CONTACTED ISUZU, AND GM. ISUZU SAID "THEY DO NOT MAKE CARS CAN'T HELP YOU" GM SAID ALMOST THE SAME THING "THATS COMMON" BUT YET THEY HAVE SWITCHED TO A NEW METHOD OF MAKING ECU'S/ECM'S.. PLEASE LOOK INTO THIS. *AK
CAR IDELS ABOVE 2000 RPM. *AK
CAR LIKES TO IDLE IRREGULARY, IDLE TOO HIGH, HAVING TO KEEP FOOT ON BRAKE TO STOP CAR. *AK
WHEN VEHICLE SWERVED TO KEEP IT FROM HITTING A DEER, THE FRONT END WENT INTO A IRRIGATION DITCH, AND DRIVER'S SIDE AIR BAG DID NOT DEPLOY. VEHICLE WILL BE TOTALLED *AK
APPARENTLY A WIDESPREAD PROBLEM, I LEARNED OF MANY MORE FAILURES OF THE SAME PART FROM BILL'S ISUZU PERFORMANCE PAGE, (WWW.ISUZUPERFORMANCE.COM/ISUPAGE/), AND WAS LINKED FROM THERE TO REQUEST A RECALL. IF THIS IS A LEMON PART, I SHOULD NOT HAVE TO PAY FOR IT TO BE REPLACED, SINCE ITS FAILURE ENDANGERS THE PASSENGERS.

295V103007 · Seat Belts:front:buckle Assembly
May 24, 1995
THE FRONT SAFETY BELT BUCKLE RELEASE BUTTONS CAN BREAK. THESE RED PLASTIC RELEASE BUTTONS ARE MARKED "PRESS." IF A BUTTON BREAKS, PIECES CAN FALL INTO THE BUCKLE ASSEMBLY CAUSING THE BUCKLE TO OPERATE IMPROPERLY.
Consequence & remedy
Consequence: THE SAFETY BELTS WOULD NOT PROVIDE ADEQUATE PROTECTION TO AN OCCUPANT IN A VEHICLE CRASH.
Remedy: OWNERS SHOULD PROMPTLY CHECK THE CONDITION AND OPERATION OF BOTH FRONT SAFETY BELT BUCKLES AND CAREFULLY INSPECT THE RED RELEASE BUTTON FOR ANY BREAKS OR CRACKS. THEY SHOULD ENSURE THAT BOTH BUCKLES ARE OPERATING PROPERLY BY INSERTING EACH LATCH PLATE INTO ITS BUCKLE, TUGGING ON THE BELT TO MAKE SURE THE LATCH IS SECURELY LOCKED, AND THEN PRESSING THE RELEASE BUTTON. THE LATCH PLATE SHOULD POP OUT OF THE BUCKLE WHEN THE BUTTON IS PRESSED. IF EITHER RELEASE BUTTON SHOWS A SIGN OF BREAKING OR CRACKING OR IF EITHER BUCKLE FAILS TO OPERATE PROPERLY, OWNERS SHOULD PROMPTLY CONTACT THEIR AUTHORIZED DEALER TO SCHEDULE AN APPOINTMENT TO HAVE THE BUCKLE REPLACED OR REPAIRED, FREE OF CHARGE. THE MANUFACTURER IS DEVELOPING A REMEDY DESIGNED TO PREVENT FAILURE OF THE BUTTONS THAT ARE NOT CURRENTLY BROKEN.
