Owner report 726225 · 2000-07-30 (July 30, 2000)
WHEN CAR WARMS UP YOU CANT DRIVE OR IT WILL STALL. ONCE WARMED UP IT WILL NOT START. I SAW AN ARTICLE ON THE ISUZUPERFORMANCE WEB SITE THAT SAID OTHER VEHICLES HAVE THIS PROBLEM. IT ALSO STATED THE REASON FOR THIS PROBLEM IS A FAULTY ECU COMPUTER MADE AND INSTALLED BY AC DELCO. I WISH I WOULD HAVE HAD THIS INFORMATION BEFORE I WENT OUT A BOUGHT PARTS TO TRY TO FIX THE PROBLEM MYSELF. IF ITS THE COMPUTER, THERE IS NOTHING I CAN DO ABOUT THAT ON MY OWN. A RESPONSE ON THIS ISSUE WOULD BE GREATLY APPRECIATED. THANK YOU. *AK

THE CAR WILL FOR NO REASON STALL, EVEN AT HIGH SPEEDS RESULTING IN A LOSS OF POWER STEERING AND BRAKES. THIS IS THE SECOND ONE THAT I HAVE OWNED, AND THE OTHER ONE HAD THE SAME PROBLEM. I WAS MAKING A LEFT HAND TURN, WHEN THE CALL STALLED, AND CAUSED A LOSS OF STEERING. A PEDESTRIAN WAS WALKING ON THE STREET CORNER, WHEN MY CAR SMASHED AGAINST THE CURB, JUST BARELY MISSING HIM. IT'S REALLY SCARY WHEN THIS HAPPENS ON THE HIGHWAY. I WAS TOLD THAT THE ECU IS DEFECTIVE IN EVERY IMPULSE/STORM EVER MADE. WHY WASN'T THERE EVER A RECALL? ARE WE …

Owner report 720403 · 2000-03-20 (March 20, 2000)
THE VEHICLE FAILS TO RUN AFTER IS WARMS UP. I HAVE CONTACTED SEVERAL MECHANICS AND WAS TOLD THAT IT IS A COMMON PROBLEM. I WAS TOLD THAT THE MANUFACTURER USES AN INSULATING SPRAY ON THE ECU THAT CAUSES IT TO SHRINK AND BRAKE CONTACTS IN THE UNIT ITSELF. THIS IS VERY DANGEROUS IN THAT IT HAS LEFT ME STRANDED ONCE ALREADY AND WITH LOOSE CONTACT IT MY CAUSE A FIRE. I DO NOT EXPECT THE MANUFACTURER TO REPLACE THE UNIT FOR FREE. I BOUGHT THE VEHICLE USED SO THEY DID NOT MAKE ANY MONEY OFF OF ME BUT SOME HELP WOULD BE NICE. I FIND THEM RESPONSIBLE SO…
