2003 Chevrolet Trailblazer Owner Comments

problem #3

For approx. 4 months I would go to get into my Trailblazer and the vehicle would be dead. Would not start unless I had it jumped. It would go 2 weeks with no problem then out of the blue, not work. I had the battery changed 2 times, alternator, starter checked with no problem. Finally after the last time, I had the alternator people come and get it and they checked it out for 2 days. The ABS system is what came up. I had to have it taken to the dealer that I purchased it from (I have only had this vehicle purchased used for a year and couple of months-vehicle is only 4 years old now) and it is the ABS module costing me $1150 to be fixed. Dealer states that it stays on after vehicle is turned off and running my battery.

Complaint received via E-mail." I would like to share the defects discovered on my vehicle since I purchased this on October 2003. Few months I drove my Trailblazer, I was stuck at the airport because it won't start and I brought it to the dealership for repair which lasted for 3 days. They told me it was just a case of low battery power. I was not in agreement with their reason. I wrote GM headquarters demanding an exchange or replacement of the truck. They declined my request, instead they offered me an extended warranty. The following year, I was driving at around 25 mph, when I changed gear all of a sudden the gear shifter came loose and practically detached it's linkage. I panicked and slowly pulled over to the side of the road. The dealer repaired the shifter for free. Then just this month I was driving on the freeway at around 50 mph, I noticed the RPM was between 7-8 and the engine revved hard, but there was no power. The speed remained constant even when I pressed the gas pedal fully. I brought the vehicle to the dealership and they found out that the transmission is defective and they replaced it under warranty. The total mileage driven as of this time is 30,000 miles."

I have had the exact problems as stated in 10047425. Windshield wipers went out completely on a rainy day, module replaced, A/C broke on a hot day-fixed, power steering assist stopped working completely making driving the vehicle nearly impossible, vehicle started on reserve power when temp hit -6 degrees, heater motor stopped working completely the next day -10 degrees. Basically this vehicle doesn't like changes in weather.
