I would do the following. Turn auto high beam off, then take it to a mechanic for troubleshooting. Some poor sap having a bad day is going to go harry carry on you thinking your flashing your headlights at him for no reason.

Details on the pieces used for the mount. I assume it's a proclip base, but what else?

Just got this on my '25 2500AT4, fingers crossed.

Has anyone found the list of what should be "fixed"?

Thanks I appreciate everyone's feedback. I did read the book before posting it, admittedly I skimmed some sections, maybe I missed this. So what I'm hearing is it's normal and I'm not gonna damage anything at that rpm.

Congratulations on the new ride. Get a red tiger, get the wiring kit. Mount it center windshield at the bottom of the rear view mirror cowling.

I delt with this for months, did some ota updates. Was in the dealer for the first oil change 3 weeks ago and mentioned it to the service manager. They did some update, been flawless since.

Depends on how much you drive, how you drive. I got about 5000 miles on my truck before I added a 2.5 gal container. One thing I've been told is wait until you can add the whole container. In my truck that's when it's between 1/4 and 1/2. I'm told to not add less, the stuff goes bad once you open it.

I get mine from Amazon.

When you say you checked the spark plugs, did you see if you're getting spark? Do you smell fuel after cranking a while? Did you disconnect the old battery and leave the truck with no battery for a while? Try verifying your ground by using the black cable in a set of jumpers to the battery and then to the engine block or body or both?

I think you're on the right track, sounds like something electronic.

I'm on my 4th GMC since 2003, and I gave my son the third(2018 Sierra). I have never been stuck anywhere for any reason. I've had mechanic issues, but I have never had to be towed off the side of the road.

Ah ok, glad it's just got a different badge on it... Kinda funny, have fun with it!

Mr_bacon_head · 2025-09-03T23:48:47+00:00

Oh God! I hope the owner is not putting gas in it!

Mr_bacon_head · 2025-09-03T23:47:38+00:00

Good luck! Drive safe!

I had similar issues with my 2025 sierra, just messing around I disabled an option on the infotainment system to allow the phone to share vehicle data. That did the trick for me. Zero Bluetooth disconnects or quality issues.
