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.

2005 Chevrolet Trailblazer Owner Comments

problem #11

  • 120,846 miles


The anti-lock brake system in my 2005 Chevy Trailblazer ls at times does not work. When I apply my brake the brake makes a noise sounding like grinding, not catching or holding, slips and goes to the floor. I have to rapidly act with swiftness within a short time to reapply my brakes in hopes they work. The brakes sometimes fail on bumpy roads, going over railroad tracks, coming to a stop at low speed, even on smooth roadways, at times entering on-ramps, and turning corners. I have been going over GM's expanded recalls to fix the problem with truck and SUV's brakes the date I saw was 12/23/2005. Can I get help with this problem"?"

Trailblazer 6-cyl

  • 62,000 miles
The contact owns a 2005 Chevrolet Trailblazer. While driving approximately 25 mph, the brakes failed. The failure occurred intermittently for three years. The dealer was unable to duplicate the failure. The manufacturer was notified. The approximate failure mileage was 62,000. The window regulator, battery cable, tank level sensor, clutch fan, serpentine belt, tight outer tie rod, hood latch, water pump, were all replaced. Also, the rotors were warped, due to rust by climate, the rear brakes pads were worn and had to be replaced. The front rotors were machined. There was an intermittent surge after accelerating from a stop. There was a squealing noise coming from the brakes. The passenger side brake lights were blowing out. The tail light circuit board was replaced. The check engine light illuminated, due to a faulty emission vent valve and hose assembly. The ABS was engaging, when coming to a stop. Updated 10/01/14

Leaving parking lot (& wanting to turn onto road) I applied my 2005 Trailblazer ext brakes. My foot & pedal went to floor with no brake at all. Thankfully no cars & going slow enough or I would have hit them. Instead of stopping at end of parking lot, I found myself entering road & seeing trees on other side of road coming up quickly. I grabbed the emergency brake lever. Scared me to death!!! vehicle then taken to repair shop. Shop owner report = hole rubbed in brake line close to driver firewall separating engine from seat area. He further said "been in business for 30+ years and had never seen this before. Seems like a huge design flaw." Rubbing on another line & pinhole there now - which would explain why my A/C was not working on driver side, but working on the pass side. How many other people had an accident" have another (")... if GM has known about a problem for yrs on several models: Very well documented on internet by hundreds (if not thousands of owners) - why won't NHTSA make GM do something" problem = speed gauge, oil pressure gauge, & radio all of a sudden stop working one day. Then some days they all work, some days only 1 work, some days 2 work??? an equipment malfunction or computer glitch? happened about 75K miles on both my auto & my dad's 2005 Chevy pickup. I live in SE, he lives in ne. Two areas of us; yet each dealership wanted about $600 to fix it. Called GM: No help available!! searched internet for repair fix, & noticed tons of unhappy owners w/ same problem: GM would not help them pay for this problem - even though it's their equipment problem. Clearly it is a safety issue: No one can tell how fast actually going & led to many accidents & speeding tickets I'm sure! time NHTSA steps in don't you think" then have the brake/ac line rubbing issue - clearly a safety issue & I hope you do something! I still have the brake line.

My gas gauge has stayed on empty for a month or so with the gas light on. I have not had the money to fix it and I put gas in it the night before the incident happened. I was driving home from a family members house a few blocks away from my house and my 2005 Trailblazer died and everything locked up on me. The brakes would not work what so ever. And I just had brand new brakes put on a couple months ago and my steering wheel locked up. My vehicle would not stop. It kept going. I am so happy that I didn't have my three small children with me. It took me three turns onto three different streets before it finally stopped. It was very hard to turn. And my back wheels were making a horrible noise and smelled really bad when I got out. I always keep a gas can in the back in case I ever run out of gas due to the gauge not working. And mind you I have only had this vehicle a year. GM should have to pay to get this fixed. This is very dangerous. Thankfully someone was watching over me and there was no other cars headed toward me. It was on a main roads that has a 45 mile an hour speed limit. I will never buy a Chevy again.

Note: This is the second catastrophic brake failure for this vehicle on September 204, 2012, while on a trip from houston tx to winona mn, I was driving down a ranch road and came to a stop to let a passenger get out and open a gate. I drove through the open gate and put the Trailblazer in park while waiting for the gate to be closed and the passenger to get back in the vehicle. I then went to apply the brakes in order to move the transmission from park to drive and, once again, the braking system failed catastrophically, and the brake pedal went to the floor. A mechanic was called out and, he too pumped the brake pedal, which hit the floor with no resistance of any kind. There were three eyewitnesses to this catastrophic failure. This mechanic replaced the master cylinder and found out that I am not the only 05 Trailblazer owner who has suffered through catastrophic brake failure events. A listing of investigations is given on this website:

, I was approaching a line of cars stopped for a red light. The weather was clear and I was decelerating and moving at approximately 20 mph. As I began to apply the brakes, they failed catastrophically. The brake pedal hit the floor, with no resistance, and I ran into the back of a stopped pickup truck?.watching it all unfold before my eyes while my foot frantically pumped the brake pedal, which hit the floor with each attempt. Although it was a front end collision, the airbags did not deploy.
