Jul 011993

Trooper 6-cyl

  • Automatic transmission
  • 32,000 miles
I purchased a used 1998 Isuzu Trooper in 1993. The previous owner kept all records of work done, per the manual. From the beginning I complained to the dealership that the car felt as though it was being held back while driving. The dealer checked out my car on two different occassions and found nothing. I then began to notice that I was putting oil in my Isuzu every 300-500 miles. I took it to a friends certified mechanic and was told this was a common problem with this vehicle and the engine needed to be replaced. I had also purchased an extended warranty with the vehicle. I called them and they requested all oil change receipts which I supplied. I was then told that I would have to pay $1000 to have the engine taken out and at that point they would decide whether it was my fault or a defect. Needless to say I didn't agree with paying $1000 since this is a known defect with this vehicle. I called Isuzu and they couldn't have cared less. I don't have the $6000 needed to replace the engine. When will this finally be remedied" how many complaints have to be filed to make Isuzu responsible for a known problem" there are so many complaints about this on the internet, yet people don't seem to know where to turn for help.

There was no accident. 1998 Isuzu Trooper engine began using excessive amount of oil. Engine with 68,000 miles went from full oil level to warning light and motor failure (bearing and block breakage) within 2-3,000 miles. Several experienced mechanics and extended warranty company (that denied coverage) say there is a know failure of these engines.
