Keep us updated because every situation is a learning experience for everyone.

I would said no because the module if it is a used module might be vin dependent and not reprogrammable like a new one. A used part will probably void the warranty . But if the owner has the diagnostic equipment and access to GM's calibration data, I guess they could give it a go.

Silver, as said by others, consult a Lemon Law attorney. Your vehicle has sat for more than 30 days and if you want to get away from it, talk to the attorney. See Steve Lehto's Youtube channel and search for Lemon Law. He explains the ins and outs pretty good. Or....you could ask if the dealership could take one out of another vehicle. This is an out there idea I know but who knows. I have had my dealership take parts off existing models to repair mine but they were not electronic. The module may be tied to the Vin, preventing an exchange. If you want to keep the truck, your best bet will be to go with the flow for now. Heck get the part number and search the GM part sites to see if the part exists someplace. Sorry about your experience with GM. Hopefully they do make it right with you. Does this apply to your truck? https://www.gm-trucks.com/new-tsb-issued-for-duramax-3-0l-lm2-and-6-6l-lp5-diesel-p206b-emission-exhaust-fluid-errors/ Talk to an attorney and see what can be done. The manufacturer will usually pay the attorney and the attorney will not take the case if he does not think you will not win. Ensure he specializes in Lemon Law!

The trim scratches or scuffs really easy. The B pillar on the passenger side is where the seat belt mechanism will rub on the trim. The seal belt does have a loop behind the mechanism but when a person disengages the belt and lets the belt fly into the return position, it often does not return to the neutral protective position. The seat belt receivers in a front bucket configuration rub on the center console. The scuffs often can be taken out by an eraser. Entry into the vehicle will just suffer unless the person takes note. The covers are easily replaced but then the cost can add up.

Get the front windshield camera checked for proper alignment or working condition. That camera controls alot of the safety features and there is a procedure to realign and recalibrate the unit.

Thanks for the update.

Since you had the windshield camera replaced, the dealership probably downloaded the latest calibration data for the module. But you should ask to ensure they did. If I remember correctly, once the camera was replaced the tech had to drive the vehicle for a few miles with the computer connected to step thru some procedural steps to calibrate the camera. Then it took a few days for the system to calibrate itself for proper operation. Have them check for proper alignment of the camera.

I have a 2019 Silverado and the Climate message was fixed with a software update.

The Auto Stop is a minor issue but it should work properly and the dealership has acknowledged that a problem exists. Other electrical issues are now raising up. You are right in pursuing a Lemon Law inquiry to prepare yourself. Try a different dealer to see what they can do.

I guess find another High Country or Note 20 and see the combination works. My Note 20 Ultra works fine in my High Country. Try a different cable?

Try placing the Note 20 into SAFE MODE and then try connecting via Bluetooth and sees what happens. Safe Mode will cut down on the number of Apps running in the background.

Onstar just released a update also. Look at your Settings - About to see what was updated.

If it comes and goes, I would think it is a connector problem. It could be a software issue but I would not put any money on it put they do happen. There was a Climate Control problem in the 2019 T1 units. Sometimes when the vehicle started up and got running, the Climate control in the radio [Software Control] would not work. A software update took care of it. What was the error symptoms and code??

Gregg, The software update is normally done over the air or at the dealership. Updating the software by the owner is not done. Since your problem was fixed the first time and is occurring again and you are out of warranty, just ask the dealership when you bring it in if it would be covered. If the problem and solution is similiar, it probably will be covered. Different solution will probably not be covered. The older trucks did not have the capability for the OTA updates. The newer trucks perform OTA updates for the Infotainment, Onstar and some other functions.
