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.

I purchased the vehicle from usados auto sales and the owner told me the car had 185,000 on it. Well after paying cash and waiting 27 days I finally receive the title and it says it has 260,000. The bill of sale he signed when he bought it also stated that the actual mileage wasn't correct. He filed my bill of sale out and didn't inform me or even right back there form he lied to me and said it was 185,000 so I contacted him and he said it was something he overlooked to just write on my bill of sale the actual mileage and I told him no I would you have spent $2500 on a vehicle with 260,000 miles and he refuses to help me. Now the vehicles check engine light is on. It leaking oil and the radio doesn't work and it keeps blowing fuses.

Whether the car is turned on, or off with or without key in the ignition, it has a small speaker or tweeter that steadily stays making a faint buzz. The center console is very loose, and if you press or knock up against the right side or the back side, it becomes louder and/or quieter. Then while in auto (2wd-4wd^or4wdl) and driving, the transmissions feels to not switch geer at the right time, or from drive to reverse and back to drive it jolts forward or back really hard.

When turn the car off and remove the key from the ignition, there are two speakers that continue to make static noise, whether I have opened the door or not. If I bump or hit the center console it will make the speakers louder or turn off. The check engine light is on for multiple codes, and I have worn out shocks. The shocks should make me feel as if I am gliding, bur I feel and jerk to every bump.

There is a defect with the vehicles electronic control module. This is not something that the consumers are causing, this defect causes the vehicle to shut off at random times, and will not start back up for several minutes. This is extremely dangerous. I have searched hundreds of forums on a fix for this only to find hundreds of thousand of people that are dealing with the same thing. Chevy needs to step up and take responsibility for this! I am sure there have been lives lost because of the vehicles shutting off on busy highways, and streets. When this happens you are a sitting duck, and have to wait till the vehicle decides it wants to start back up. This happens while driving on the highway, or city roads. At random intervals. It is extremely dangerous, and I am amazed that there has not been a recall for this. I have seen in chevy online forums that this affects several years of the trailblazers, and envoys too.
