I had taken my 2003 h2 hummer to have the front end aligned and 2 new tires placed on the front . I complained to the tire dealership the moment I had driven my vehicle maybe 10 miles of it not driving right . I took my vehicle back to the dealer 3 times with complaints of it not driving right. Thinking maybe they did not tightened something back up when they did the alignment . I had only driven my vehicle approx. 5 times (4 times to the dealership with complaints)and the 5th time I drove it . I was in an accident in when the vehicle pulled to the right I lost all control and my vehicle was totaled . It is my understanding that nitto grapper has recalled tires and this was the brand of tires that was put on my vehicle . The right front tire was flat after the crash an this is one of the reason the tires are being recalled . I believe it was either the tires or the alignment not properly being done that caused my crash .

What 2003 Hummer H1 owners say
Most recent owner complaints, unedited.
Abs brake fault light repeatedly comes on. Vehicle returned to dealer (cerritos hummer) seven (7) times for repair and fault continues.
While driving 55 MPH vehicle stalled. Vehicle was towed to the dealer for analysis, but mechanic could not resolve the problem.
The brightness of head lamps on both sports utility vehicles and many foreign autos is a continuous hazard. Even when I've moved the rear view mirror to night shade, the outside mirrors blind me. Large vehicles awash the interior of my car as if I were sitting in front of a landing airplane. I realize by the time anything is done about this, I'll be dead but thought I throw my complaint in here, especially about hummers.
