Sometime in February of this year, the engine failed on our 1999 Isuzu Trooper, possibly due to low oil. No warning lights or symptoms of any kind - vehicle just quit on route 95 in mansfield while my husband was driving home from bowling. Car was towed to local garage, where they confirmed that engine needed to be replaced - in fact, the tow truck driver had literally picked pieces up from the pavement underneath the vehicle. Upon searching for a new engine, we discovered that they were not easy to find unless purchased directly from Isuzu, and according to Consumer Affairs website, this is primarily because this type of failure is common among Isuzu manufactured in late 1990's/early 2000's. our regular mechanic, and several others questioned, confirmed that the Isuzu's were notorious for this type of problem. Bottom line, it would cost us $5000-$6000 dollars to replace the engine, which is about what we owed on the car.

Excessive oil burning.

- Belleair, FL, USA

Engine oil burning issue. 1999 Isuzu Trooper S. automatic transmission. Vehicle burns over 1 quart of oil per 3K miles. Has done the same since I bought the vehicle in 2003 with 52K miles. Now has 93K miles. Based on online research, this is a design problem with the oil flow ports within the 3.5 liter V6 and is a widespread problem.

1999 izuzu Trooper oil consumption ( a quart of oil every 450 miles).

- Falling Waters, WV, USA

1999 Isuzu Trooper purchased new. Began experiencing excessive oil consumption between oil changes around 50K miles. Regularly took a qt of oil every 1K miles. Oil and filter changed every 3K. Dealer service manager said this was normal oil use for this engine. At 128K engine fails 4 hrs from home (Sept 2003). Nearest dealer is called and says it has thrown a piston due to lack of oil. We pay to have the vehicle towed back to our local dealership service department. Engine is replaced at our cost. We have engine dismantled by ase certified mechanic and the failure was a spun rod bearing. No evidence of lack of oil. This is a terrible engine and would recommend anyone driving an Isuzu with this engine get rid of it asap.

I have a 1999 Isuzu Trooper that I purchased on 7/27/02 with 67,000 miles on the odometer. It now has 72,800 miles. It is a V6 with automatic transmission, and is in excellent shape. During my ownership, at four separate occasions, as I was coming to a stop at about the 5 mph mark, the throttle has opened fully while in gear! I have had to "panic brake" the vehicle and push the transmission selector to "neutral". when I have done this, the engine has raced to 6000 RPM+ and held, so I have had to turn-off the ignition switch each time. After gathering my nerves, I have restarted the engine. The first three occurrences happened in traffic, so the problem has been a real safety concern. Last night, this problem happened in my own driveway. I nearly "took-out" my garage. After keying-off the ignition, I restarted the engine. The engine raced a second time while the transmission was in "neutral", so I shut it off again. I then turned it on again and the engine went to idle. This problem is pretty "hairy", and on Monday I intend to call the local Isuzu dealer (billings, Montana). But, I really think this complaint needs to be brought to the Isuzu technical people. Thanks for your time.

Engine failure while passing on state highway at approx. 65mph. Last sevice at 55,000 miles. Engine had oil. No warning indicators before or after failure. Dealer states piston rod thrown. Local engine shop states this is a common problem with this engine.

- Ruffin, SC, USA

This car has been a nightmare. Basically an accident waiting to happen. The manufacturer and dealership have given us the run around on the vehicle. It stalls when the vehicle comes to a slow. Occurs at major intersections when turning or waiting to turn. Has been serviced 8-9 times for same problem. 3rd time this past month. Car breaks down on way back from dealership! getting no help from Isuzu incorporated.

- Labelle, FL, USA

The vehicle misses out and then dies while driving. It may miss out days before dies or the same day or not at all. Speed, weather, and how long it has been running have not been an issue. It has even died when I had been dirving for 2 hours and was going 70 on the highway. It has been in 5 times and they say they can't find any thing wronge but it keeps doing it. The driver seat slips forward even though the track has been replaced twice. Before the track was replaced the last time the seat was fixed you could just set in it and lean forward and it would tilt and slid. It has been in 4 times for this among other things.

Vehicle will stall while braking only at any speed. Taken to dealer 3 times, could not determine the cause.

Vehicle burns quart of oil every 1500 miles. Isuzu claims 1 qt per 1000 miles is acceptable industry norm.

- Lockport, IL, USA

The vehicle has stalled while in motion on several occasions. There has been no warning prior to any of these failures. In each case, the vehicle was able to be restarted immediately after the failure. This has been occuring intermittently for about 6 months and the servicing dealer (hall Isuzu in newport news, va) has been unable to determine a cause. Although the servicing dealer doesn't appear concerned, I feel very strongly that this vehicle is unsafe and that eventually this defect will cause the vehicle to be involved in an accident. While I am not a mechanic, the sudden nature of the failures seem to indicate a problem with the electrical system.

Vehicle stalled on several occasions while driving. Nlm

- Missouri C, TX, USA

My Trooper first entered the shop on December 13, 1999, and was in for the same problem on two other occasions. The car has run hot three different times, and has the engine has run many miles with a mixture of oil and water in the engines internal components. I am very concerned about an engine failure at highway driving speeds, and also about future engine life. The manufacturer has been little help. My car is out of the shop now but was in for many weeks. 8ak
