“Isuzu Trooper 1999 problem after problem, engine burning oil. After the engine was replaced, the engine light illuminated at least 30 times. The dealer gave the consumer all types of excuses until finally they said they didn't know what was causing the light to illuminate. There were other problems such as a hard shift with the transmission, water leaking through the sun roof, difficulty starting the vehicle, uneven tire wear, in just 65,000 the consumer has gone through 3 complete sets of tires. …”
NHTSA complaint #10113417, filed 2005-03, 40,000 miles“I bought a 1999 Isuzu Trooper limited edition 1 year ago this month. Since buying it I have had the starter replaced, the alternator replaced twice, the small block was bad because of a failure with the dipstick to read the correct amount of oil. My son was involved in a mva due to the fact that the vehicle would not stop as the engine decided to race while he was coming to a slow stop. Thank god no one was injured in the accident. The car revs up at an idle at a stop or slowing down position, and now the vehicle is in the garage because the transmission is bad and the alternator went again. …”
