Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

2003 Hummer H2 Owner Comments

I have a major problem with leaking and rattling coming from the sunroof and now I cannot get it to function. It sounds like it might actually fly off when I am riding down the road. I have heard very many complaints on this same problem from other H2 owners. I am not worried about it working properly but I am very concerned about it flying off and causing serious injuries to my self or other people it may hit.

I bought a 2003 Hummer H2 brand new. Since the day I got it had many problems, both electrical and mechanical. The steering is very hard and the breaking is ineffective at times. I showed them a copy of the bulletin on this website. They did not acknowledge any problems. The issue still persists. Many electrical issues seat memory problems, mirror don't work..etc. Eventually the electrical issues fixed. Roof leaking water from the reading light on two occasions once because of sunroof issue and the second time because of the outside roof light. Now most recently I have been having a problem with the "check engine oil" light comes on every 5 to 6 weeks and way before an oil change is due. This has happened at least 5 times so far. Everytime the engine is missing oil. The dealer says that Hummer allows the engine to burn one quart of oil for every 100 gals of fuel. I said what am I supposed to do when that light comes on. The service manager said pull off the road and check the oil. I said what am I supposed to do if the oil is low. He said add oil to the engine. I said so I have to drive with a couple of quarts of oil in the back all the time" the light comes on every 5 to 6 weeks. I said how many Hummer have you sold? he said many. I said how many you know of do that? he said none. I said if none do that, why does mine do it? and if this normal why none of the others do it" the dealer refuses to acknowledge any leak of oil or any burning of oil by the engine!!!!!!!

  • Automatic transmission
  • 24,000 miles
Consumer was going 70 mph and the two front tires locked, while the two back tires kept moving. Vehicle then continued to skip. The driveshaft was replaced. For the past 8 month this vehicle has been in the shop more than at the consumer's home. The vehicle has needed a new alternator, transmission, battery, ignition and drive shaft. The roof leaked and the consumer had to replace one of the side windows.
