2004 Chevrolet Trailblazer Owner Comments

problem #5

Feb 242007

Trailblazer 4WD 6-cyl

  • 32,262 miles


When checking my brakes I noticed that the inside of the front brake rotors where corroded and rusty. The vehicle is a 2004 Chevrolet Trailblazer with 32,262 highway miles. Approximately 25-30% of the inside of the rotor were rusted and had worn down the brake pad. So only 70% of the inside brake pad was being used for braking. This causes the brake pads to wear unevenly. Appears that this could be serious in an emergency situation. I checked the rear rotors and they are starting to do the same but only 1/2" on the outer edge of brake rotor is rusted. I checked the recalls and there were none for brakes. I checked with Chevy and they are not aware of any problems. In checking websites, trailblazerclub and trailvoy, other people have had the same or similar issue. I would assume that there is a problem with the metal.

October 5, 2005 I bought a 2004 Chevy Trailblazer. At time of purchase, I was offered a tires for life deal. All that was required of me was to have the maintenance done at Chevy and to have tire rotations and oil changes every 3000 miles. I have been doing this. Last oil change and rotation on Jan 8, they told me I needed front brakes. 57,500 miles on vehicle. I said okay and set up an appointment for Jan.15. At that time, they told me I would need new rotors also. At this point I was starting to mistrust the service department. They put my vehicle back together and I went to big O tires for a second opinion. Upon their checking my vehicle, they found all four rotors to be bad! it appears to be a manufacturers defect. The manufacturer is using a defective metal to make the rotors. Big O claims that it is a potential law suit and they should do a recall. They have had numerous cases come in like mine not only on the Trailblazer but other Chevy trucks and SUV's. the brakes weren't actually wore that bad but all four rotors were rusted and pitted. These rotors had never been turned they still had manufacturer clips on them. It was definitely a sign of poor quality parts not regular wear and tear. Also, Chevy makes me wonder why they did not notice this earlier? I have been in their shop every 3000 miles for rotation, they should have noticed this right away. It is as if they were trying to hide something. Here in 2 weeks I will be getting new front rotors and brakes. Then as soon as I can afford it I am going to get the back rotors replaced. But this could prove to be dangerous to many people and should be looked into. Thank you for your time and consideration.

- the contact stated that he took the vehicle to a dealership for an inspection on 1/9/07. He was informed by the mechanic that the vehicle will not pass inspection next year because of the brake rotors. The service department indicated that all 4 rotors were warped. The contact believed that the rotors should not be in need of replacement at 21800 miles. Updated 01/31/07.

Trailblazer was taken to place of purchase to repair pulsating brakes. Vehicle is under warranty with under 26,000 miles. Dealer refused to repair. Said GM would not pay for repairs. Rusty rotors was the diagnosis. Contacted GM rep (lisa) and she told me I lived in the rust-belt and that was the reason for the rusty rotor condition, not defective parts. She refused to authorize repair. Suggested I return the vehicle to the dealer, have them cut the rotors (at a rate of $150 per axle). Submit the bill to GM and they would decide whether to reimburse me.

Trailblazer 4WD 6-cyl

  • Automatic transmission
  • 17,000 miles
The brakes were making a loud screeching noise. I took the truck to the nearest Chevy dealership. The truck only had about 15,000 miles on it. Upon inspection, the service department found that all four brake rotors were completely rusted and pitted. This vehicle is housed in a garage when not in use, so rusting should not occur easily. All four rotors and brake pads were replaced. This is just one of 21 problems I have had with this vehicle- not to mention the severe back pain the driver's seat is causing me.
