Outside temperature displaying 50 degrees regardless of actual outside temperature. When actual temperatures below freezing this represents a hazard. When temperatures above 50 degrees air conditioning not responsive (even when temperatures in excess of 100 degrees, "heater" comes on due to erroneous outdoor temperature reading). Poor fuel mileage results from incorrect air/fuel mixture at actual air temperatures more than 20 degrees +/- 50 degree system temperature.

The headlight wiring inside of the lens assembly over heats and melts the electrical connector going to the bulb and the insulation on the wiring. This has happened to both headlights on more than one occasion. Had to go and have the electrical wiring plus connector replaced.

Larger occurring issues which could effect safety include the vehicle randomly deciding to change from 2wd/A4wd/4wdh4wdl whenever it wants to under various weather/road conditions (including perfect weather and road surface) and occasional random ignition system failure this is not safe at all I have taken it to the Chevy dealership and they said it is a safety issue and that they need to do a recall on it they have had several rigs like this one come in for the same issue.. I believe that Chevy GM needs to do a recall and have this fixed before I or someone else is injured or killed..

Our 2002 Chevy trailblazer mirrors will not reset to the memory positions. The mirrors change positions by themselves and have to be readjusted everytime the car ignition is turned off.

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.

I have a 2002 trailblazer in which 4 out of the six instruments in the gauge cluster have stopped working correctly which in turn could be a safety issue.

Both rear window regulators went out at the same time not from wear hardly used them makes to much noise. Four wheel drive differential locking hub locked in won't come out. Electrical problems with radio, dash lights, heated seats just to name a few. Idle not right stalls out while in park sometimes. Nothing fixed yet have to save money because cost to much to go to dealer, it costs a $100 just to have them hook up to machine and then it says nothing is wrong but all this is wrong, it does not compute.
