I bought it used in Oct 2007 with 60,000 mi on it. The oil gets changed every 3,000 mi but I need to add a qt of oil every 700 mi. As far as gas mileage (it's the pits ) maybe 11 mpg at best. I thought Isuzu was a good buy (guess not).

Vehicle uses excessive oil. This is a common problem with the 3.6L in 2000. Check the Isuzu forum online. On highway trips, uses 1 quart every 200 miles. On shorter trips in town, can go 500 to 700 miles before needing a quart. It doesn't leak, and doesn't burn. The problem is caused by the oil not draining down after being pushed on top the cylinders. It eventually has to be burned, or sent through the exhaust, particularly on long trips. On shorter trips, you stop before to much is burned off or pushed out, so it drains back. The oil drain back holes are to small and to few. I'm told there are 4, but on later engines there are 10 per cylinder. Isuzu should be made to own up to the design problem and fix the engines. I bought mine at 22,000 miles, and now have 100,000, and it has always done this, but gotten progressively worse.

I have owned this SUV fron new. I have changed the oil and filter each and every 3000 miles. I have used fully synthetic oil, mobile, 10W-30. The vehicle uses at varying rates from 1qt of oil per 1000 miles to 1 qt. Per 2000 miles. While it is within "Isuzu guidelines" it is obviously excessive. I have discussed this with the dealer at each service trip and they just chuckle and say your doing better than most.

Car has lost power and gas mileage has been cut in half (maybe 12 mpg at best) has only 39000 miles...dealer says the tubes that recycle un-burned gas fumes are clogged and need cleaning but they nor Isuzu has a tool to do the job...it's hard to believe that a huge company like Isuzu would have such a problem.

This intermittent problem could cause someone to get injured if they are in freeway traffic and the vehicle will only go 25 mph!!! this vehicle has an intermittent problem of stalling when stopped at intersections (vehicle is idling). The car can be resstarted immediatly. However, after starting it has little power and the maximum speed is 25 mph. Both the "check engine" and the "reduced power warning indicator lights" come on. It has been to two dealers a total of 6 times and they have not resolved the problem. I am afraid to drive the vehicle as I have been in 50 mph traffic going only 25 mph and feared for my safety. I would appreciate your review. The dealer has replaced the throttle plate, re-wired the wiring harness and made other adjustments. They still cannot fix the problem. This needs investigation! thanks
