I have a 2005 chevorlet Trailblazer. I have had both speedometer and gas gauge quit working on me. Have been told it will be around $500 each to be fixed! I feel that this is a safety hazard and should be a recall by GM. 2005 models have the worse overall rating with these 2 malfunctions be the top 2 complaints!

My 2005 Trailblazer instrument panel constantly fails - the speedometer stops working which is a safety issue. The gas gauge has been fixed once already and is now broken again. The vehicle has power surges which is another safety issue. The transmission shifts the car up and down when trying to slow down causing power surges. This is another safety issue. The following are other issues which this model vehicle: Stereo cd player stopped working, the check engine light comes on when the gas cap light, the lights flicker also. I ought this vehicle used and with a cracked front bumper which the dealer didn't fix (dealer stuck a little bondo on area and repainted it so I thought it was a new bumper when I accepted the car after repair. It cracked in a matter of days) and I know this was caused due to the surges in power. A severe safety issue. The vehicle has serious electrical problems the Chevrolet should stand behind and fix. It is not fair to the consumer. I have checked the web and have read many, many other similar complaints. Chevy owners should fill a class action lawsuit against Chevrolet if they don't do a recall and fix these problems. I experience a fender bender accident when my vehicle didn't stop and bumped another cars back bumper causing an accident and an insurance claim. I am fed up with this vehicle but can't afford to replace it. Linda vanauken

Gas gauge quit working, cost to fix at dealership est. $1800, exterior lights flicker from high to low beam while driving, dealership cant find problem, car seems to "jump" or leap forward while coasting or when apply brake, dealership cant find the problems or cause, car stalls and RPM drop if gas pedal not pushed, windshield wipers started automatically and wont turn off. Had to take fuse out, therefore no wipers. All these items are a safety hazard to the family driving. The only problem the dealership could find was the gas gauge sensor which is not under warranty and cost $1800. One thing after another is going wrong with this vehicle and I will never buy another one or recommended one. This has been going on for over a year now. No one can find the "problem".

2005 Trailblazer: 1) speedometer would read wrong speed while driving, needle would max or zero out while driving, and now is completely not working; can not determine correct speed which could lead to ticket or accident. 2) wipers stay on with switch in the off position, must pull fuse to stop them; wipers are distraction going across dry window or must stop to put fuse in if weather requires. Currently vehicle is in shop for repair. First replacement part for wipers did not solve problem. Through viewing other internet comments this is not an isolated problem. It needs to be addressed before an unexpected driver is involved in an accident do to these issues.

On two separate days, within a two week period, my speedometer stopped working correctly. The first time in went to zero mph and stayed there. A couple of days later it worked again. The second time, on the highway, it read incorrectly - said I was at 55 but was actually going 85 (spouse was following behind me in another car).

I purchased my 2005 Chevy Trailblazer in the spring of 2007. Around December 2007 my speedometer started hanging up. It is still doing it today. The worst time for it to happen is on cold days. I did not have a problem with it this summer. Now with the fall of the year and colder days, it has begun hanging up again almost everyday. Because of this I am not sure of my correct speed. I searched the internet and found multiple complaints regarding this same problem. Chevrolet has issued many recalls on other makes and model, but has yet to issue a recall on this problem. I feel this is a safety issue that needs to be corrected on this make and model, as it has been on others.

At low rpms the truck will lunge forward /reverse depending which gear you are in. This happens when it wants it is not a constant. It idles high and surges. First occurrence happened in Feb dealer did nothing. Next occurrence it almost hit my daughters friend when she passed in front of me. Again dealer did nothing and finally the last occurrence it lunged into a tree. Again dealer and GM found nothing. I have documentation from the mitchell repair company that states that the year make of my truck this has happened. However GM denies this. This truck is not safe.

My Trailblazer has an intermittent problem, when I am coming to a stop at a stop sign or red light it will suddenly lurch ahead or surge ahead. It will sometimes do it while I am driving slowly through a parking lot. It is a major safety issue as it could cause me to proceed into a main intersection. The local dealer showed me a GM notice that stated they were aware of a problem, but could not find a solution to this. This is a very dangerous issue.

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.

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.

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.
