Trailblazer 4WD 6-cyl

  • 42,000 miles


Failure of the gauge cluster on a 2004 Chevy Trailblazer currently with 59,300 miles. About June 2009 the tach continually read incorrectly. Dealer tried to mislead me to bring it in for a diagnosis at a cost of approx. $100 I told them its broke why should I pay for a diagnosis. I had read about the problem on -line at edmunds, com.,my SUV had 41,000 to 42,000 miles on it. In July 2010 my gas gauge started to occasionally malfunction, now Jan. 2011 it is incorrect. In Nov. 2010 my charging gauge started malfunctioning. I also have since read online of the same problem on other similar year GM trucks ans SUV and they have recalls on them. Its just a matter of time for the speedometer gauge to read incorrectly. Please help, these malfunctions are not safe.

All of my gauges on my dashboard completely turn off and then randomly turn back on. It is very dangerous to drive around with no speedometer, gas gauge, olil, battery, tachometer or odometer on. Then it all of a sudden will turn on. It needs to be recalled. I took it to a repair shop and they said it would cost around $500 if not more to have them take apart my dash and look and then possibly send it out to seeif it can be fi.xed there are numerous people I have found online with this same problem with the same vehicle.

Horn has intermittent issues of working - we have taken to the dealership on several occasions and then it works. They do not want to take apart the steering wheel assembly to research the problem regardless of the number of times we have had the vehicle to the dealership. Now that the warranty is expiring, I am sure the problem will be researched since it will be at our cost. The horn only seems to work when the car is first started and the steering wheel is moved shapely. Since it is under the air bag, the dealership doesn't want to deal with it.

2004 Chevrolet Trailblazer. The vehicle's A/C air output works fine, but when you switch it to heat, the output for this is diminished considerably. The vehicle heats up fine, but even when the airflow is entirely at the dash (none directed to the floorboard) the output of air for the heat is very low; so low it can't even be felt unless the hand is placed directly in front of the vent no matter how high the setting is. Veh has been taken back to the dealer (under warranty), and was told no diagnostic problem was detected; everything is working properly. Compared my vehicle to others of similar make/model/year, and dealer says all work the same. This is not true because last year, I could not stand the heat on setting of more than two because the output was very good. Now, it can be put at a higher setting, but with little heat output. I communicated with an internet service technician who says it is the air flow door that is not sealing properly. The internet service technician also said it is difficult/tedious to fix this problem. I think the dealer just doesn't want to mess with it as it is under warranty.

Major electrical problems inside the vehicle. I have owned it less than a year.the vehicle has been in the shop twice in the past two weeks. Exiting the freeway the I had a complete power failure. The vehicle completely stopped and locked up and there was a semi truck behind me! my vehicle was moving and in "drive" when this happened. I had two of my toddlers in the car with me! the vehicle was taken into a local dealer and unfortunately they could not find anything wrong with it. Apparently, when the vehicle is restarted it erases the codes in the engine as to what caused the problem. Well, it happened to me again this evening. Same problem. This will be my 5th time of bringing this vehicle in for electrical problems in less than a year. I only have 9400 miles on the vehicle and bought it brand new. I do not feel safe driving this vehicle with my 5 children as passengers. Is there a way GM can get me a better running vehicle? I paid a lot for this vehicle and am very unsatisfied with it's performace. There always seems to be something wrong with it. The connell Chevrolet service here in killeen has been very helpful. I feel sorry for them because they did not sell me this vehicle but they are the ones nice enough to try and fix the multiple problems.
