What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 1991 Isuzu Impulse, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

Each component in detail
What the reports in each category say, in the owners' own words
Electrical
Reports naming the electrical system — wiring, battery, charging, control modules, infotainment and electrical accessories.
From owner reports, verbatim
I HAVE A 1991 ISUZU IMPULSE AND IT'S HAVING ECU PROBLEMS. MY MECHANIC SAYS IT NEEDS TO BE REPLACED. I SEE THAT THIS IS A RECURRING PROBLEM WITH THESE CARS, AND IT SHOULDN'T FALL ON THE SHOULDERS OF THE CONSUMERS. *AK
THE CONSUMER STATED THAT THE VEHICLE IS EXPERIENCING THE SAME IDLE CONTROL PROBLEMS AS STATED IN PREVIOUS RECALL REGARDING THE ELECTRONIC CONTROL UNIT. *YH
Driver assistance
Reports naming forward-collision avoidance, lane keeping, back-over prevention, cruise control and related electronic driver-assistance systems.
From owner reports, verbatim
CAR RACES ENGINE BADLY IN THE SUMMER WHEN TEMP OVER 80 DEGREES-WONT IDLE. *AK
THE SYMPTOMS OF THIS FAULT ARE MOST NOTABLY ERRATIC IDLE, IDLE REVVING AND DROPPING, IDLE DIPPING OFTEN WITH ENGINE DYING, IDLE HANGING HIGH ABOVE 2,000 RPM, AND ENGINE DYING OR STALLING FOR NO REASON WITH NO TROUBLE CODES. THESE SYMPTOMS WILL OFTEN ONLY OCCUR IN WARMER WEATHER AS THE METAL CIRCUITS OF THE CIRCUIT BOARD SEEM MOST VULNERABLE TO SHORT CIRCUITS AT SOLDER CRACKS WHEN THE TEMPERATURE WITHIN THE CAR IS ABOVE 80 DEGREES FAHRENHEIT. IN TEMPERATE CLIMATES, THE SYMPTOMS MAY FIRST SHOW THEMSELVES AS SOON AS THE WEATHER WARMS AND PLAGUE THE OWNER ALL SUMMER LONG, ONLY TO SUBSIDE IN THE FALL WITH THE COOLER WEATHER AND THEN REAPPEAR THE NEXT SPRING.

Engine
Reports naming the engine itself — including stalling, misfires, oil consumption, cooling and internal engine components.
From owner reports, verbatim
THIS IS A REOCCURRING MANUFACTURER DEFECT. PLEASE ISSUE A RECALL ON THESE ENGINE CONTROL MODULES. *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 WAITING FOR SOMEBODY TO BE KILLED FIRST?

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
