Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“My 1990 Isuzu Trooper is exhibiting dangerous revving and dropping of the idle. The truck accelerates without warning and is impossible now to drive safely. It is my understanding that the ecu in these trucks is faulty due to manufacturing defects. I further understand that thousands of others have these problems. Please initiate a recall of these vehicles and force Isuzu to repair these dangerous defects at their expense, not the consumers'. Please take action on this extremely dangerous situation. …”
