1989: “The ecu has caused erratic engine behaviour and complete engine failure leaving us stranded on numerous occasions. Mechanics have been unable to resolve the issue and the vehicle has been untrustworthy over it's entire life. Many times the ignition system has failed in traffic with our babies in the car leaving us stranded in the heat. This unit should be recalled. It would be nice to have some of the hundreds spent on mis-diagnosis, motel bill's and towing service, etc. Reimbursed by GM/delco -Isuzu. Please contact me if necessary. Dt”
