Have read this speedometer issue can also cause other malfunctions on instrument panel such as cruise control issues. . +driving a car with a broken or faulty speedometer is very dangerous.

5 Electrical System problem

Failure Date: 05/22/2021

Several months ago, I was at a fast food drive up window. I had my drivers side window down while paying for my food and receiving my food. It was down pouring and the inside of my door got pretty wet. I wiped off the rain as best as I could but everything was soaked. The very next day the drivers side door controls started to go haywire. The window button stopped working and my door locks only worked occasionally until they stopped working all together. My side mirrors can no longer be adjusted from the drivers seat. I have to get out of the vehicle and manually adjust both driver and passenger side mirrors. I'm not sure if there is a short in the wiring from the rain or just what is going on. I asked a parts dealer to see how much it would cost to replace the drivers side door controls module and he was of no help except to say its a recall part because of moisture. I've looked this up and I see there was a recall but my VIN isn't on the recall list. I don't understand why my vehicle is excluded considering this appears to be exactly what this incident generated the recall in the first place. I further looked into the investigation you had on the Trailblazer's outside of the salt belt states having the same issues with the moisture and issues that arise from the damaged door controls. I'm not sure if I would be considered in the expanded recall but I'm certain I should be as this is exactly why my drivers side door controls failed. I feel this is a huge safety issue as I don't know if there is a electrical/wiring short and not being able to adjust the side mirrors is an impairment. There was no warning to let me know anything was wrong. The system just went out just that fast. Please advise me how to proceed with my next steps to get this resolved. Also, my low beams went completely out the other day and replacing the bulbs didn't fix that issue. I do have a recall scheduled for January to get the headlights fixed and I'd like them to fix both issues. Thank you.

14 Electrical System problem

Failure Date: 10/26/2018

I have a 2006 chevy Trailblazer with only a little over 80,000 miles on it. I have been having issues with the stabilitrak system. I will get read outs about the stabilitrak needs to be serviced or the stabilitrak has kicked in when it hasn't. The stabilitrak will try to in gauge for no apparent reason when appling the brakes. It happens when I am backing out of my driveway, coming to a stop or just applying the brakes to slow down. It happens on all type of road surfaces. This happens when it is bright and sunny outside, on dry roads, highways, streets, dirt roads and day or night. It does it at fast speeds and very low speeds. It makes a strange noise when this happens however the stabilitrak doesn't fully in gauge. The repair shop looked at it and told me that they think the computer modal is not communicating with the stabilitrak system. This started a few weeks ago. So I'm not sure how this will affect the brakes when driving on the snow and icy roads. I have seen other complaints on the same type of issues.

26 Electrical System problem

Failure Date: 07/09/2015

On 7/9/15 I brought my 2006 chevy Trailblazer (purchased used in October of 2013) to my mechanic at midas muffler in bangor due to an issue I was having for the last few months regarding the electric window/door lock on the drivers side whereas I have been intermittently unable to roll my windows up or down and I have been locked in my vehicle and unable to get out three times. They removed the door panel and found that water had been leaking into the door and caused corrosion to the module that controls these functions. I was told there had been a recall for this issue. They had called the local chevy dealership who told them that the recall on this vehicle had been fulfilled in August of 2013. On 7/13/15, I called gm to inquire regarding this recall since when the recall was issued, it stated that "parts for the remedy are not currently available. " I have not received any letter stating that parts are now available it is, in my opinion, that the "fix" that was done in August 2013 did not "fix" the issue and this has caused the same problem to reoccur. Gm told me that the fix would be my financial responsibility. The recall notice on your website also states, "vehicles whose modules were modified but not replaced as a part of the previous recall remedy must have their vehicles remedied again under this campaign. " I am not sure whether or not the module was replaced in August 2013 as I did not own the vehicle at that time, however, I do feel that the remedy that was done on that date did not fix the leakage issue and therefore gm should be responsible for replacing the module now and also fixing the leakage issue so this does not occur again. This is a safety issue as I have been locked in and unable to get out of my vehicle three times already, and also, according to the original recall, this can be a fire hazard.

Failure Date: 04/10/2015

We were traveling from spokane, wa to portland, or, when we got to richland, wa the check engine light came on. We stopped and scanned the computer and gave us a code for a faulty pedal sensor. We erased the code and turned the Trailblazer on and it came back on in about 10 minutes. We read online that other people that have Trailblazer ss are having this issues and there was a recall on the sensor and they are getting theirs replaced. I talked to autonation Chevrolet and camp Chevrolet here in spokane, wa and they both have heard of the recall and the issue but since it won't show up under my VIN number they will not honor the recall. They won't 100 to 150 to diagnose when it took me 5 seconds and they want us to pay about 600+ dollars for an repair that should be free. I read about the sensor and our truck is doing everything it says it will do. When you are at a light and go to push the gas pedal it boggs down like about to die then lunges forward and shifting hard between gear 1 or 2. Can someone please help us with this and help us get the dealership to work with us. If we continue to drive it an accident could happen any moment. This is a huge hazard!!!.
