Bought used 1999 Isuzu Trooper with 48,000 miles. Took it to mechanic because it had a problem starting. Discovered engine leaked more than 1 quart of oil per 1000 miles. Isuzu replaced engine just before 60,000 miles, but still has problem starting. Mechanic determined 3 or 6 fuel injectors are bad, and needed to be replaced. Trooper stalls at slow speeds, and engine will rev while idling.

While driving at 65 mph vehicle stalled. When this occurred vehicle lost power and coasted to a stop. Vehicle was towed to a dealership, who indicated that this occurred because there was no oil in the engine. The engine was replaced, but the problem recurred.

Vehicle burned up to four quarts of oil in between routine oil changes. The manufacturer told the consumer since the mileage was beyond limitation of any warranty, there was nothing they could do.

1999 Isuzu Trooper.. oil consumption leading to severe motor damage. ( over a quart per 1,000 miles) have heard of several of the same incidents with others driving Isuzu products having the same outcome as I. a complete motor overhaul with 64,000 miles on this Trooper. Other instances with fewer miles. Isuzu is aware of the problem, only manufactured this particular model for two years. Isuzu was notified and then in return let my mechanic knew where to begin repairs and to what extent they would be. I live in a very rual community in Maine and I know of at least three other instances with the same outcome. More importantly Isuzu does not stand behind their vehicles even when they know there are problems.

I purchased my Trooper new. I have all of the print outs of the oil changes made which are at or below recommended intervals. At approximately. 25000 miles I reported a shifting problem and they replaced the transfer case because metal filings were found in it. Then 2000 miles later the problem re-occurred and they replaced the entire transmission. It was bought in back 500 miles later for and adjustment on this again. At 40000 miles the cd player jammed and they replaced this with a new one that took 8 weeks to receive. We had followed the directions in the manual. Following this, the cd player again jammed @ 51,000 miles and they refused to repair it -out of warranty- at this point we realized that part of the directions in the manual were faulty. We did report this to the dealership to no avail. It is still not fixed because they will not release the code to repair it. Each of the times that we have had this in while still under warranty, we have had to complain to receive a rental/loaner car while it was in for several days at a time. Then at 60000, there is an evap. Code that indicates there is an issue with the vent valve and it is not performing correctly, but the dealership has told me 3 different times that it has been in 3 different causes. Now at 74,000 miles, I have just been informed that the short block has to be replaced and the heads may be cracked. The last oil change was at 71,800 miles and the oil light did not come on. They claim that there was no oil in the engine but, the oil dipstick says that there is a proper amount. This is a 7400+ repair. This is the 12 the time this vehicle has been in to the dealership. All repairs have been done by an authorized dealer.

My 1999 Trooper threw a rod in the engine. It is not drivable. I have had the Trooper in the shop 3 times before with other problems, before the warranty was up. The dealer did not want to discuss the problem. In trying to find another engine I was told that this was a common problem and that it was very hard to find an engine. No new ones were made, nor was a repair kit.
