2005 chevrolet trailblazer ls 4wd speedometer failed as driving down the freeway. Was going approxiamately 60 MPH and speedometer registerd 10 MPH. It corrected it self and for a couple days it was fine again. Then it started repeating same failure, and stayed the same. It was taken into a gmc dealer and the repair was done. The speedometer was replaced, with a total bill of $463.09, paid my myself, since the warranty was just barely over.
2005 Chevrolet Trailblazer acceleration complaints
Page 4 of 4: complaints 71 to 76 of 76, newest first, as owners wrote them.
Purchased 2005 chevrolet trailblazer ls oct.28 06. Since then, to date, veh. Has been in shop (dealership 4x). 1. Brake repair. All 4 calipers were replaced. This vehicle had only 22,000. Miles. In shop very 1st week of purchase. 2. Been complaining of flickering lights. Was handed a gmc printout stating they did not know cause. So therefore the dealership, hood chevrolet, covington la. Could not do anything about it. 3. Complained of engine acceleration while applying brake, coming to a stop or a slow speed in a parking lot. Fear that I may crash into someone. Received printout from gm stating this was normal. But I see this is a hazard. 4. Complained of seat belt "riding" on the neckline, restricting blood flow in left artery on neck. I see this a major problem. I commute 26 miles one way to work at a hospital. I thought I would be safer driving my trailblazer, now I fear for my life. 5. Complained of popping on front end. Service had to order sway links and replace. Did not solve problem, still have frontal popping while turning left or right, reverse and forward. It is progressively getting worse. Found out gm certified tech. Did not properly align calibers when installed. I have paid to much for this $23,000. Lemon. Action should be taken. Sarah dykes, bogalusa louisiana.
Speedometer went haywire on a 450 mile trip got about 200 miles and the speedometer read 90 MPH when cruise control was set at 79 MPH. Went to get off of exit and when I stopped it didn't go back to 0 instead when I started driving again it went below 120 and was hanging directly down. We got it back down to zero by having to start it and turn it off 5 miles at a time. It has happened 3 times now in less than a week.
Cruise control shut down. It was set at 70 MPH. Vehicle was going uphill and it felt like the engine had died. The speed drop was sudden and drastic, luckily there were no vehicles following when it occurred. It would not resume nor reset by turning cruise control switch off and on. Vehicle did accelerate using foot pedal. Started vehicle up next day to take it to dealer and the cruise control worked fine. Contacted dealer and was told he never heard of this problem before and maybe it was just a fluke happening.
With cruise control set going down hill. The vehicle doesn't hold the speed you set it at. Depending on the size of the hill it will gain between 5 and 15 MPH.
Dt: the contact states while driving two engine lights come on and the engine powered down. When the vehicle was powering down she could press the accelerator to the floor and it moved along. When this happened none of the brake lights came on. Therefore, contact's vehicle was almost hit by an 18 wheeler. She continued to drive the vehicle at the low speed. This happens at no particular speed. The vehicle has been to the dealership ,and they replaced the computer and throttle body. The dealership has been unable to diagnose the problem.
