I have a 99 Isuzu Trooper S, and have owned it less than one year. I bought it with about 51.500 miles. It now has 8000 miles on. I live in a small town and I use this vehicle for minimal purposes. Getting mail, groceries, etc. Small errands of the sort. I was on the way over to my in-laws and noticed a ticking sound and then the oil light flashed. They live about three blocks away. My father-in-law checked the oil and then added four quarts before it even registered. Neither myself nor my husband have ever noticed an oil stain or any evidence of oil loss. After he added the oil, the knocking subsided and it seemed fine the next couple of days as I used it around town. Then on my way out of town, in about 20 mi, I heard a knocking sound, but the temperature was fine and there were no warning lights on. I decided to stop anyway and to call a tow truck in fear of any further damage that driving may cause. The service station that looked at it has informed me that the engine is shot. The Isuzu company has a powertrain limited warranty for a period of 60 mo/60000, whichever is earlier. I have been told by my local Isuzu dealership that the "in-service" date is 03-03-99, and that it is out of warranty. Although it is still under the 60kmi and only four months over the 60 months, they will do nothing to help. I also contacted the Isuzu owner relations department and received the same response. In my further investigations, I have found numorous complaints of the same type of problems. It seems to be that this mysteriously missing oil problem occurs in the 98 and 99 models. I'm currently at a stand still on what path to take. My vehicle is at the local service garage, unfixed. I have contacted the better business bureau with a complaint. I am waiting to hear back from them. Meanwhile, could you please investigate this problem. Thank you.

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.

Intake manifold gasket repeatedly needing replacement. Oil consumption.

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.

Defective head gasket replacement. Mr. There was a crack in the lower gasket. The mechanic stated the gasket may be defective and this problem shouldn't have happened this early. The consumer requested reimbursement for the repair(s). Scc

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.
