I currently own a 1999 Isuzu Trooper which I purchased about 5 months ago. Some of the problems are starting to happen as you all have mentioned. It burns about 1 quart of oil every few weeks and I have to constantly check it to make sure the engine doesn't burn up. On top of this, it is burning out of the exhaust quite badly. The engine runs very rough and makes strange grinding like noises that are there for no apparent reason. Every once in a while on random occasions it decides to not start, so I give it a few tries and then it eventually starts. Besides all of this trouble, it has excellent room for storage and it is good in the rain safety wise. What I don't understand is: Why are there so many problems that have not been addressed by the manufacturer or any that they have admitted to?
I found out that starting the engine is kinda tricky. There are around a dozen sensors attached to various parts of the engine that need to "green light" an engine start. If one of those fails...
Seven of these have failed in the one I had. It recently auctioned for $1000 (6 years old).
I have a 1999 Isuzu Trooper, which was a lease I purchased back in 2002. The car ran like a charm until about 75000 miles. Then I had to really keep a close watch on the oil.
The oil consumption is huge in this car. I found myself adding and/or changing the oil every 500 miles. Eventually, the engine seized on a highway while on the way home from vacation. I replaced the engine for about $3600. I still have to watch the oil, but it seems better. It does burn quite a bit out the exhaust.
My starter went about 8 months after the engine replacement, which ran me about $500 and now my fluid lines attached to the transmission are severely rusted. Another $200 I may need to spend to fix so my transmission doesn't blow.
I'm stuck with the decision to fix or just trade it in. I now have 106,000 miles on it.
On another note, it is a very comfortable car and handles well in the rain and snow. The 4-wheel drive is excellent. I will never buy another Isuzu after this as they don't stand behind their product.
