Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Truck will not start for no apparent reason. Key turns, sounds like it will start but does not. This has happened on several occasions and seems to be an ongoing problem for other Hummer owners too. I just had it towed once again to the mechanics shop. This is the 5th time within one year. Unable to leave my house during an emergency, child related.”
NHTSA complaint #10995755, filed 2017-06, 115,000 miles“I believe there is a problem with the H3 Hummer 2006 I request to bring it to a dealer to get it checked. Has to do with the turning, reverse. When vehicle is put in neutral still seems in drive. Sounds like a plastic noise. Needs to be checked by a certified mechanic”
NHTSA complaint #11340038, filed 2020-07, 150,000 miles“The anti-theft engages randomly and prevents me from starting my car. This is not only inconvenient but could endanger my safety. There are numerous complaints listed about this defect by other H3 owners. This should be recalled. I just purchased the car less than 1 month ago.”
NHTSA complaint #10903588, filed 2016-09, 97,800 miles“Sometimes when I go to start my car it will not start. Then I wait exactly 10 minutes and it starts right up. This has been going on for about four years now. It happens about six times a month”
NHTSA complaint #10840242, filed 2016-03, 50,000 miles“The H3 will not start. Dash screen keeps showing the passlock activated and won't turn off. Computer thinks the H3 is being stolen. I have tried to reset and no luck. I had this problem about 4 weeks ago and changed the fuel pump. Then it happened again last week and now on 28 march 2020. Engine is turning over and electrical systems light up, but sounds like fuel is not getting into the fuel pump again. After doing some research, finding others having the same problem. Recommended procedure is to wait 10 min, still no luck. Waiting 15 min seemed to work before, but now it doesn't. …”
