What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
Starting at around 55k miles, my isuzu 99 trooper has started burning around 1qt of oil per 600-700 miles. This causes excess wear on the engine and most drivers have experienced seized engines due to this problem..
Dt: consumer states that the fuel gauge is not working properly. She is concerned that she will run out of gas and she cannot keep up with how much gas she actually has.
When my brother purchased his isuzu vehicross in 2000 he has had a problem with the windows and had always tried to fix them but nothing seem to work. He also took it to the dealer to get it fixed and nothing was ever repaired. Now I own the vehicle and everything thing I have tried does not seem to work.
