The headlamps have quit working when driving at night but will come back on later. This has happened several times. I found GM recall number 14291 that is supposed to include 2006 Chevy Trailblazers and pertains to this problem. The local dealership told us that our vehicle has a vin number that is not covered. It would seem that all model 2006 Chevy Trailblazers would use the same HDM modules in them when they were built. Is ours covered?
Just need a recall sheet for shipping vehicle.

In a very severe head on crash 4/8/2022 the air bag did not deploy.
Brakes failed for no apparent reason around 8:00 am that morning. My friend and I was driving to my home in his 2006 Chevrolet Trailblazer after many stops that morning. We was on the interstate doing 65 MPH. I noticed the traffic ahead approaching and I said "cars" indicating to my friend to slow down. He said "I have no brakes!" We narrowly missed the first cars and while readjusting we came into contact with the driver side of three vehicles rolling us on our side! I broke both my arms escaping thankfully with my life. We had no idea what suddenly and unexpectedly lost brakes. Weeks afterwards I started reading about the stabilitrac and steering sensor on the 1 of many Chevrolet vehicle defect issues. Around that year and I believe was the problem. I have been out of work and tried to explain this to people with no reply. I read an article about Chevrolet told about the issue and refused a recall. Senator Blumenthal requested an investigation but I haven't seen anything after a judge requested a Chevrolet CEO deposed. If this vehicle has these dangerous problems please know that it almost killed my friend and i. https://gmauthority.com/blog/2021/03/u-s-senator-asks-nhtsa-to-investigate-gm-over-faulty-steering-sensor/ Thanks if anyone is listening.

I was sold this vehicle with a corroded frame and was untold of this issue
While driving both low beam headlights turned off. This has now happened on more than one occasion.
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.
Low beam headlights stop working, when driving at night. This problem is happening frequently.
.+Electrical system. 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. Not only can it put you in danger, but it can also jeopardize the safety of your passengers, and other drivers and pedestrians on the road. As for the law, you can also be ticketed for operating a vehicle with a broken speedometer, which can cost you fines and court fees, and even risk suspending your drivers’ license. .+My mechanic has not had the chance to look at it yet as he isn't open till Monday. .+No other warnings were given prior to failure.
