Example complaints

Engine cooling: “I checked my oil level 3 weeks ago and it was fine. I change my oil every 3000 miles. I added a quart 3 days ago for a long trip I was taking. While driving down to billings, mt, my car suddenly stopped. It had not overheated or shown a warning sign. My car was bone dry of oil! The engine has seized. I did everything right...this is clearly a design flaw in the car.”

Transmission and drivetrain: “The contact owns a 2000 Isuzu Trooper. While driving 30 MPH, the vehicle hesitated and lunged forward. The mechanic stated that the gasket transmission pan had a leak and the gasket was replaced. Approximately one week later, the failure recurred. The mechanic stated that the vehicle had two transmission pans and the second gasket should be replaced. The gasket was replaced, but the failure recurred two months later while driving 35 MPH. The mechanic stated that there was a leak in the accumulator cover and made the replacement. As of december 4, 2007, there had been no further occurrences. …”

NHTSA complaint #10210795, filed 2007-12, 81,558 miles

Fuel system: “Three or four weeks ago I received the following note from Isuzu: Isuzu motors limited has determined that a defect relating to motor vehicle safety exists in certain model year 2000 troopers having 4-wheel drive and automatic transmissions equipped with tod (torque-on-demand). In certain types of high-speed, frontal crashes, an interior fuel line and fuel hose can be separated, allowing fuel to leak from the vehicle. Fuel leakage could cause a fire and result in serious injuries or death . I tried to contact two Isuzu dealers in my area. …”

NHTSA complaint #735110, filed 2000-10

Air bags: “At highway speed (75mph) a boom noise was heard from the front of the vehicle just after contacting the warning strip on the highway. Vehicle began to swerve and fishtail then flipped end over end 3-4 times approx. One - two hundred yards down the highway. Injured but experienced driver was suspicious of a possible suspension or steering failure and concerned that air-bags did not deploy.”
