Purchased feb 1, 2002. since then have had nothing but problems. had into 4 different dearlerships fixing many problems but after each visit another problem occurs. from tail lights burning out, windhshield wiper motor failures, instrument cluster replaced, heater control panel replaced once, memory mirror modules replaced 2 times, heated seat switches replaced 2 times, rear window defogger/replaced entire rear window 1 time, battery replaced 1 time ( said battery was at fault for current problems) battery was fine and charged me $ 150 for new battery that was not the correct battery replacement, exhaust gasket became loose/loud and had to be replaced, the fuel pump replaced because it just cut off as i was on the expressway going approx 65 miles an hour, i had to get to the side of the road quickly- had to be towed to dealership. problem fixed, however after i picked it up then the current problem began. i could go on and on with the problems that i have had. present problem is that whenever i turn on the heat it dies out with no warning---just stops and stalls. dealership says they fixd it but upon pick up the problem still exists. gone to pick it up 2 times, but when i start it and put on heat, it dies all over again even after dealership claims they fixed it. i live in chicago and it has been a cold winter. almost caused a crash on another expressway on way home from having the airbag sensor and a complete brake job done and all fluids changed. this vehicle is not worth $ 37,000 and i feel it is time that gm accept some responsibility for this lemon of a vehicle. it is my only vehicle and i am still paying dearly for it but lately cannot even use it as it remains in one dealership after another at my expense. i will not purchase another vehicle from gm. i need help and answers as i am not getting anywhere even with this vehicle still under warranty.*ak

Since purchase (feb. '02) to present (july '03) there has been a "humming" / vibrating noise coming from my vehicle's instrument cluster. it is very prominent during slow speeds, such as in parking lots and when beginning to accelerate from a stop. representatives at dealer's service dept. have told me that this is "normal with trailblazers".*ak

The brake light went out multiple times without warning. the dealer was aware of the problem. there were no incidents to report at this time. *ak the consumer stated when the vehicle was warm, the was a noise in the front end, the dealer replaced the axle seal and bearing, the o2 oxygen sensor was replaced. the 4-wheel drive was inoperative. *jb *nm

My turn signal switch was defective from the day that i bought my 2002 chevy trailblazer in october of 2001. it took at least 8 visits to various dealerships on long island and mount vernon, washington (i moved several times) before it was repaired satisfactorily in 2004. i raise this issue because i read about gm's recall of their 2003 and 2004 and it should also apply to their 2002 vehicles

Vehicle is experiencing various electrical problems such as intermittent operation of the wipers, electric seats that move on its own while driving, electric mirrors never stay set and move randomly when driving. computer module replaced 5 times. *tt

There is a malfunction in electricial system wiring causing all back lights to go out without wear. . problem happened numerous times. dealership replaced fuses, wiring, etc.. problem still occurring. *ak

I have a 2002 chevrolet trailblazer and the electric mirrors are erratic - they won't hold their memory. i understand this is a big problem with trailblazers. when you start car you do think to check mirrors everytime and it can be dangerous when you go to change lanes and realize that the mirrors have lots their memory. i have almost had numerous accidents due to this defect. i feel it should be a recall for trailblazers as this problem has been reported by a significant amount of trailbazer owners. *nm
