Eight problems related to cruise control have been reported for the 2005 Chevrolet Trailblazer. The most recently reported issues are listed below.
I bought this car at the end of March of this year with under 100,000 miles. The first thing to go was the gas gauge, about 2 months after I bought the trail blazer the needle went south. It actually hovers around 6 0 ' clock. Then a couple nights ago driving home I had the cruise control on, I took it with the hand button and looked down and the needle never moved, it was stuck at 65. It's been 3 days and the needle has moved but the wrong way, to the right going up 75, 80, 90, then back down to 65 and staying there. I have looked into replacing the gas gauge and I was told the entire dash would have to be done at a price of 1200. 00, I should not have to do this, Chevrolet should be held responsible.
While driving to work my cruise control shut down and my speedometer stopped working. A couple weeks later the speedometer began working and now it has stopped again and stuck on 55 and doesn't move regardless if the vehicle is on or off. The cruise control won't work. I am very frightened to continue driving without knowing what speed I am driving. I can't afford to keep spending money on this vehicle to repair all the problems it's had. Wondering if the speedometer is covered under my 100,000 mile warranty. Please help.
My wife was driving our vehicle with our two children in the car. She was traveling at highway speed with the cruise control set when the speedometer of our vehicle faulted. It started showing she was going 110 then 20mph then 50mph and so on and so on. She pulled over, phoned me and we called our insurance company to see if towing could be provided. It would have taken over 2hrs for towing assistance so she traveled the rest of the trip (approx 105miles) following another vehicle in hopes that they were traveling at a safe speed. The following day I research this issue, brougth my vehicle to a dealership and they explained it was a known issue with a 05 Trailblazer and the gm had a class action law suit for replacement of this part they state the instrument panel needed to be replaced. However, we later found out that our vehicle was not part of this litigation and we were stuck paying the bill. Not only does gm know this is a safety issue, they are unwilling to compensate or take corrective action for their customers. Needless to say I am very upset and frustrated for the safety of my family and the fact the gm has not offered any remorse.
Bought this vehicle used in oct 2010. Not long thereafter, noticed the speedometer wouldn't work all the time - normally it works when I first start driving but when the vehicle warms up, it stops working all together. I think it's a safety issue if you do not know how fast you are going. The cruise control also doesn't work once in a while. Most of the time it does, but occasionally I can't get it to go on at all.
Cruise control on 2005 Trailblazer when the resume is pushed it will go wide open until it gets back to speed ,which could cause a crash if it was unexpected.
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.
