Trailblazer EXT

  • miles


Chevy trailblazer02 model, about 40K miles in 2005 the car died on us 2 times and we couldn't find out what was the reason we had to ask for jump and it kept going on normal, then suddenly after about a couple month I saw that the battery was leaking, and damaged some A/C pipe lines under the battery, had to replace the battery and wash and clean all under and around the battery to remove the acid stuff. After that the tailgate where the third brake light is, started making noises everytime I opened it, when checked I found that the part where the rear window is affixed to the tail gate where broke and the escrews are hanging by it self which made the rear window loose and standing out, and about a week ago now that I have 61K miles in 2009 the rear brake light went off, took it to dealer and they told me about the recall on those lights and so they fixed it, which when I picked up the SUV and drove it with the family about 45 miles trip when suddenly it started blowing air and making a strong and deep noise sounded like a bus or 18 wheeler passing by, which made us cancel the trip and go back to dealer to find out what have they done to my car, take a guess, I was told that it's common on those Chevy's the fan clutch to go out and that it really lasted long on my car and yes it's something normal that happens, but it cost me $950 to repair it yeah sure very normal, it seems like GM parts and labors now are costing just as the german cars. Shouldn't GM make all those issues recall if it is known that are defective and are happening to most of the cars.

Trailblazer EXT 4WD 6-cyl

  • Automatic transmission
  • 68,000 miles
I backed of the garage and heard a loud noise. As I pulled forward the truck moved very slowly for how far the gas pedal was pushed. I went to go in reverse again but the truck would not go into reverse and could hear a loud whining from the motor. I this just happened to day but I figure it's the transmission. Also, when I bought the truck I had problems with the temp. Sensor and the air conditioning the dealer took care of the problem with the air but the outside temp. Sensor is still broke. I don't know which is worse the failure of the transmission or, seeing all the like complaints on this site with no action.
