CarComplaints.com 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.

I just bought this vehicle. The headlights won't come on the low beams. I pulled the blinker handle back for high beams to come on. I hold it back while I mess with headlight switch finally low beams comes on and I can push blinker handle forward to engage high beams to stay on.

My 2007 Chevrolet Trailblazer head lights go off when I'm driving down the road. They do come back on after I stop for a minute or two. I can't drive my vehicle at night because of this issue. I looked up my Trailblazer using my VIN number and it said there were no recalls on my vehicle. I've had other issues with my vehicle to. :(

The daytime and low beam headlights would turn off randomly, which would make for dangerous and unsafe driving conditions. Now they no longer work. I have received a letter from Chevrolet about this problem, but because I have more than 150,000 miles on my car, I must pay to have this problem fixed. It will cost me more than $400 dollars and a one way trip of 35 miles to my nearest dealership to get it fixed. The part can only be replaced by a dealership service center, because the computer must be reprogrammed, forcing me to use their services instead of my mechanic.

While driving, my low beam headlights intermittently go off making this car unsafe to drive at night. This happened the first time Aug 20,2017 and has happened many times since and seems to be getting worse, 10-15 times in the last month. This happened the first time while sitting at a stoplight. I was close to the motel I was staying at so just drove straight there. Since then it has happened while driving in the city and on the highway in the rural area I live in. My daytime driving lights also go out in the same way.

The contact owns a 2007 Chevrolet Trailblazer. Without warning, the low beam headlights failed to function properly. Months later, the manufacturer sent an extended warranty campaign letter. The contact called the manufacturer and was informed that the vehicle exceeded the mileage limitation and they refused to repair the vehicle. A dealer had not inspected and diagnosed the vehicle. The contact was not provided with a solution from the manufacturer and was uncertain of when the vehicle would be repaired. The failure mileage was not available.

Right brake light continues to go out and the connector is burned and corroded. Also, I am continuously replacing my headlights and brake lights. Once replacing, the light works for about 3-4 weeks. It appears there is a problem with the brake light connector circuit board. Please help!

Problem with fatality risk. In Aug 2016 low beam headlights and running lamp began turning off randomly, intermittently. Will usually work when vehicle is first started, fail in transit. Increases in frequency, progresses to failure. On lit streets, I have no indication that I am essentially invisible. Relay replaced by dealer, paid for 10/1/16. Mileage 137K at that time. Began failing again 7/2017. Drm module had failed. Part alone cost $267. Prior to dealer repair, I had tried auto parts store modules as well, and each 2 burned out within 1-2 months. GM has issued a recall for this very problem, I think number 14921, established May 2016. It includes 2006-2007 Trailblazers. They extended it to 12 years old or 150K miles, whichever first. I contacted GM. They me that my VIN does not come up so they will not cover this. Will not tell me what disqualifies my vehicle, other than VIN not coming up. Did online chat with the rep and S/he said that I have to file a complaint with you, no internal complaint department, nobody I can appeal to within GM for help. I have another appointment to fix this, but no assurance that it won't just keep failing, since this is the 4th time I have done a repair in 2 years, I purchased the vehicle 3 years ago, so this may have been a recurring problem prior to my owning it. I do not have a copy of the repair bills from last year, but my appointment for next repair is this coming Tuesday, 9/5/2017.

I first noticed the problem Oct. 2016. The low beams went off on my 2007 Chevy. Trailblazer. I stopped at an auto part store and bought new lamps, when I went out change the lamps I noticed that my lights were working. So I didn't change lamps. Then it happened again on 04/2017 and again they came back on then received this notice in the mail, and though the time limit hadn't pass the mileage had. If I had received the notice sooner I would have had it fixed then. I was driving on highway at the time! I called the 800 phone number on the notice I explained the situation to the person on the phone and I told him that had gone over 150,000 at the I had gone over 3,000 miles, he told me that my car would be taken care of and he gave me a case # ( 8-3085956921) he said someone call me with in 24 hours. After 2 days someone called me and said that could not repair my SUV because I had gone over the 150,000 miles.

Approximately 2 years ago my dim headlights went out as I was driving at night. I thought to switch to high beams and luckily they worked on high beam thank goodness this was a road I knew well.. I have no way of knowing how often this happens during the daytime. But it occurred several times after this. I had my vehicle checked and was told it was a relay. Changed it and problem solved, until now. The issue is back, GM sent me a "special coverage" letter, I called the number on the letter and was directed to take it to a chev. Dealership to confirm my vehicle does have the headlamp driver module issue then Chevrolet will let me know what would be next. They did confirm my vehicle has the issue but Chevrolet will not cover my vehicle because it is over the mileage of 150,000. Really" is my vehicle no longer worth fixing or is the issue supposed to resolve itself after the 150,000 mile mark? a salesman called me after I left the dealership to ask about me trading or getting rid of my vehicle, is this a ploy just to sell vehicles"

The contact owns a 2007 Chevrolet Trailblazer. While driving approximately 75 mph, the low beam head lamps turned off. The contact had to slow down and pull the vehicle over to the shoulder to a complete stop. The contact turned the light settings knob, but nothing happened. After approximately five minutes, the low beam headlights illuminated. The contact stated that the failure occurred eight other times. The vehicle was taken to jeff sweeney Chevrolet in springfield, Ohio, but the vehicle was not diagnosed due to the cost. The contact then drove the vehicle to an independent mechanic (car-X in fairfield, Ohio) who diagnosed that the head lamp driving module was defective and needed replacement. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 149,000. Updated 08/23/17

Four years ago this month while driving at night and in the rain our headlights went out. We could only use our high beams. Took it to the dealership the next week and was charged $282.81 to fix. Have been hearing for years about this problem with Trailblazers but never a recall. This is ridiculous.
