What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
My truck did not have takata airbags (so they told me) but my airbags did not deploy. When I told this to the isuzu spokesperson (2-3 yrs later) he told me that no car's airbags deploy in rollovers because they are not programmed to do so.
Tread separation on tire, loss of vehicle control, impact with retaining wall, considerable damage to vehicle.
While drivng at 45mph, when making a turn, the vehicle rolled over, resulting in vehicle total loss. Please describe details.
After coming out of a parking garage at low speeds, vehicle skidded on icy surface, hit a curb and rolled over, driver sustained injuries.
Consumer was driving on wet pavement and was making a turn and the vehicle skidded of the road and rolled over.
There has also been an oil leak; however, the failure was unable to be duplicated. Oil leaked onto the steer plate and coated the entire exhaust system and the components of the engine.
Power steering hose started have massive leak all of a sudden, and it was replaced the following morning. The power steering fluid had sprayed all over everything under the hood, which included soaking the alternator, which in turn made the alternator start to surge at time, causing the transmission to go in to back…
On dec 27,2005 he came home at 3:30 am in the morning, he got in the shower and when he got out our dog started to bark, so he looked out the window into the driveway when he heard a pop. So he looked again and flames started to come out of the passenger front fender.
