Print this page Notes: The 2002-2007 Chevrolet Trailblazer is known for many things, but perhaps it is most famous for its faulty fuel gauge.

This gauge flip-flops more than a politician during election season. Some report that the gauge says "empty" after a fill-up, while others report the gauge says "full" when they're running on fumes. Either way, there's one thing everyone seems to agree on: the darn thing is just wrong.

Following hundreds of complaints and a few accidents allegedly caused by the malfunction, the National Highway Traffic Safety Administration (NHTSA) opened an investigation into the issue in May 2011. Unfortunately for frustrated owners, no recall has been announced.

It was bought in 2011, and ever since me and my wife are so sick in tired of buying and buying and buying these valve stems that are junk and it looks like 15 dollars to buy but its 60$ to put in..this is garbage completely useless.. you fill the tire up and you can hear the air come out of it its like a every couple of months I've had to buy one now I think its time to say something this should be a recall to put regular old fashioned valve stems and take them TPMS out of the cars/trucks some people cant afford these things every couple of months.

Chevy vehicles have had multiple problems with their TPMS (tire pressure monitoring system) on all vehicle types. The failure occurs at the wheel itself. Although this is a safety device, it has turned into a useless piece of equipment which no owner can afford to keep up with. What happens is that the pressure monitor system at the wheel is very sensitive and fails quickly. The amount of repair for one unit costs approximately $200, and that is for one wheel. Chevy should be doing a recall on all vehicles, that have the TPMS system. This problem is not unique to one vehicle, if you do a google search on TPMS and Chevy or GM you'll find that this is a common problem. After I had the first one replaced the dealer told me that I shouldn't bother because it will only fail again. The dealer also said that he wishes that Chevy would install a better system, because it will advise you that your TPMS is not working properly, and after it fails, drivers will ignore the message, which is a larger safety issue. I don't know how the dot would allow GM to continue to use faulty parts which is a safety related item. The consumer shouldn't have to pay for their mistakes, and hopefully a person doesn't lose their life before action by the dot. I hope to see a recall issued soon.

This vehicle has had a number of electrical and /or computer problems. The first set of tires on the vehicle were worn out because the computer would say they had low pressure, so we would fill them and check them with the onboard tire pressure, otherwise it would continue to say the tires were low. The gas gauge goes from full to empty and back at least 10 times a day, they say at the service dept it's the fuel sending switch. Service stabilitrac warning comes on at various times. I think all warnings (lights and through the computer screen) have come on at least one time, some we had to stop the car and look up what the light was in the book. Now the ignition switch has something wrong, the steering wheel will not lock when the car is shut off and the key is removed. Then the car won't start unless you work the key and the switch. Today it started and then quit when you let go of the key and it goes to the run position. When you turn the key on, there is weird noise like electrical short or something. There have been problems with window switches and regulators.

Friday October 29th 2010, I was driving on interstate and my rim blew a hole. My tire is fine, but I have a huge hole in my rim. I didn't run over anything and I was just getting on the interstate so I was doing around 50mph. In the right hand lane thank god or I would have taken cars out with me. I was just driving and I heard this very scary, loud sound and it jerked me off to the right and I pulled over and called for help. I took it to a dealer and they have in the 30years he worked there ever seen anything like it. The district manager ok'd for me to get a new rim. My concern is I'm afraid to drive with the rims. Are they safe" I have a family, will the others blow out like the one did? how can you guarantee me they are safe?" I want 4 different rims due to I don't feel safe.
