Trailblazer was parked in driveway on a 72 degree day and the rear windshield simply exploded.
I was at work on 8-18-2011 when CO workers told me that asked me if I had a black chevy Trailblazer because someone saw my rear window explode. I went outside and there was glass all over the ground outside and my window was broken in little pieces. I came home and searched the web for similar problems. I found this had happened to other people and there was a number to contact the manufacturers. I called them but they told me there aren't any open recalls pertaining to this type of problem.
The passenger side exhaust manifold cracks. Once manifold cracks exhaust fumes make there way into the cabin of the car. Also the extra heat causes wires to melt and could be a possible fire hazard. After researching the failed part I have realized it is an extremely common problem with the Trailblazers and gm has done nothing to correct this failing part.
Temperature gauge reads higher than it should and gas gauge fluctuates.
While driving, the speedometer will rise and fall erratically. I have been told by my mechanic that the instrument cluster is bad and needs to be replaced. Upon internet research, I have found this is a common problem with gm truck and SUV models in the years 2003-2006. Trailblazer is the only model that gm has not covered in a recall for this part malfunction. How can it be safe to drive and not know what speed I am traveling at? I have an appointment with Chevrolet tomorrow. They will not fix the problem until their technician can diagnosis it. . . And charge me an extra $99. 00, even though the problem has all ready been diagnosed by certified, experienced mechanic. At the time this first occurred, the speedometer registered 115 mph; my husband estimates he was driving 25-30mph.
My instrument cluster malfunctions on a regular basis. The speedometer tachometer and gas gauge all go crazy and register information that is no where near accurate. The speedometer says 60 when sitting still, and gas gauge needle is at 5:00 when there is a half tank. If you start the vehicle and quickly turn it off enough times, the gauges will eventually get back to normal for a few miles,. Then go back to strange numbers and process has to begin all over again, don't know if the temp gauge is accurate or not.
2003 chev Trailblazer. Mileage is 95,000, speedometer shows misleading info, first started reading about 20 mph over actual speed, over the past month has increased, now at full stop reads about 100 mph, then when vehicle is moving the needle is pointed straight down, past 120 mph.
My speedometer in my 2003 Chevrolet Trailblazer stopped working, all the other instruments work. This is not safe. I did some research and found that a number of complaints have been filed on this very issue. Gm should replace this part. It appears they knew there was a problem.
Second incident dashboard: service brakes,antilock abs warning light. Says to seek service. Abs malfunctioning any time it goes below minus 10 degrees for the past two years. Assume that the abs system will not work, and it is a safety issue. Malfunctioning abs. The first event we paid to have service bulletin check grounding of wheel and body sensors. The next year it went away after a day of the car not being used. Why doesn't the govenrment get Chevrolet to repair permanently the malfunction before any accidents occur.
3rd brake light aplique.
1) spare tire release defective and cannot lower spare. Found problem with spare release by belle tire when rotating and buying new tires at 58,000 miles. 2) no spare available. My child in the car stranded on a road endangers my family. 3) requested gm assistance center for assistance with no answer for two months. Was finally directed to dealer for estimate. Gm dealer indicated that the problem is common on the gm Trailblazers, and in need of repair. They did not know if the replacement part was redesigned. Gm assistance center could not answer if part improved , and would not offer any compensation for replacement of another potentially bad part that could leave a motorist in an unsafe situation .
Almost weekly we have to have acorns removed from blower in dashboard because squirrels get up inside dashboard from underneath the car and stash the nuts in the dashboard and the nuts get all caught in the fan and cause it to shake the entire dash board,. . . . Was told when I called to make appointment for blower motor problems the service department told me the problem was probably acorns in the dash and they were going to have to charge me for the service call and there was nothing they could do about the squirrel and acorns getting into the dashboard. In fact they were nuts and when I talked to chevy about fixing the problem I was laughed at and they told me to go to local hardware store and buy screen and stuff it in hole. . . . . I don't even know where they are getting into the car and I don't think I should have to pay for someone to fix this issue because it is a manufactures defect in the design.
Purchased a 2003 Chevrolet Trailblazer on 2/28/03 and within a few weeks the paint wore off the bottom of the right and left rear doors. Had the vehicle repainted. Within a few days it wore off again. Chevrolet will not repaint the affected areas stating it is an environmental issue. The dealer states they believe it is a manufacturer defect in design. They also stated I would need to put running boards and molded mud flaps on to prevent the problem from getting worse. They are however not willing to put them on at their expense. If this was an environmental issue than all vehicles would have the same problem not just me. In speaking to Chevrolet customer assistance I was told that they are aware of this problem with the Trailblazers however they are not willing to do anything about it.
It takes 3 times longer for the rear heating system to blow "warm" air then the system in the front. I have taken it to the dealer 3 times and still have the same problem. The last time I was told that "engineering" was notified of the situation.
2003 Chevrolet trail blazer extended with plastic piece that flew of vehicle. Customer states that it was replaced once under warranty but that was a year and half ago* the consumer stated on the back of the window, on top of the rear hatch there was a piece of plastic that held the middle brake light. The plastic piece flew off the vehicle.
