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. Notes: Carrying the not-so-proud traditions of its 2002 predecessor, the 2003 has a handful of instrument panel malfunctions that can leave you guessing your speed, engine temperature or how much gas is left in the tank.

Goodyear tires cracking, all four tires, P245/6517 fortera silent armor purchased July 22, 2010. Tire identification: Dot pj8T 65hr 1910, approximate 23,000 miles, tread depth remaining 8/32. These tires are cracking in threads, circumference and rim line. I have contracted Goodyear case #1402275. They will give me a tire credit of $182.82, I feel these should have been replaced free of charge. There is no abuse on these tires, well maintained, no cupping. I have many pictures that I would like to email. I will be purchasing new tires 06-09-2014.

Got a flat tire on the road. When I attempted to drop the spare from the back bottom of the vehicle it was frozen in place. Cable holding spare was frozen with rust. This part failure is dangerous to people of similar vehicle makes because it must be happening to others. I was under the vehicle trying to break the tire free in traffic that could easily have led to me being killed trying to break spare tire loose and it caused me longer delay and exposure to dangerous traffic due to part failure. I could not get it loose and had to have the dealer replace the whole cable. Dealer from Chevrolet said cable was frozen. 2003 Chevy Trailblazer.

The contact owns a 2003 Chevrolet Trailblazer. The vehicle has kelly safari trex tires, size P245/70/R16 (na). While driving approximately 50 mph on a snow covered road, the vehicle began to fishtail into a spinout unexpectedly. The driver pulled over to the shoulder of the road and inspected the vehicle. She noticed that the tire exploded on the rear driver's side of the vehicle. The tire tread debris exploded in all directions in the road due to the massive force. The tire was changed and replaced with a spare tire. The vehicle was able to resume normal operation and then taken to an independent tire shop. Two replacement tires were ordered for the vehicle. The failure and current mileages were 12,000.

My family & I were on our way back from Chicago on I-55 near Pontiac il when we had a tire blow-out on our '03 Chevy Trailblazer. I tried to remove the spare tire from underneath the vehicle, but it would not lower. (Chevy have a winch system for the spare tires) the tire would lower about 2 inches, but would not lower completely. I tried several times to lower the spare w/ no results!! if this system would have worked properly I would have had the flat changed in a matter of minutes. The spare tire storage is a good system, if it works! there was no rust on the cable, or anything hindering it from working the way that it is suppose to. I followed the instructions in the owners' manual to no avail! it just didn't work! because of this faulty system, I had to call a towing service to get our vehicle hauled back to bloomington from outside of Pontiac. The bill for said tow, wound up costing my family $255. What good does it do to have a spare tire on a vehicle, if you can't retrieve it from it's storage spot? there was absolutely nothing I could do to get my family off the side of the interstate, so we had to wait for a little over an hour on the shoulder until the tow-truck arrived. Like I stated, if this system had worked properly, I would have had the spare switched in a matter of minutes & saved my family alot of stress not to mention $255!

Trailblazer 4WD

  • Automatic transmission

Right rear tire popped / blew out unexpectedly while driving approx. 40 mph. Vehicle is a 17 day old 2003 Chevy Trailblazer. I'm concerned about the safety and well being of my 6 year old child as well as myself while driving on a "repaired" tire, that may possibly have some type of defect with the tire. The dealer/service department seem more concerned about convincing me that I must have ran over something and everything will be ok, because they will repair the tire.
