Transmission was confused, service stabilitrak, and blind spot fault?

[thefrey]

Had an interesting morning. Started up the Yukon and it kept unlocking itself multiple times. Looked down and got a service stabilitrak and traction control. Blindspot warning was broken. There was no underline underneath what gear I was in… I could still shift from P to R or D but the initial shifts were very hard and the backup camera didn’t come on.

Drove it 100ft, let it idle for a bit, turned it off and started it again 2x… then everything went way.

Anyone had this issue and is it common? I feel like I could easily understand the unlocking since it maybe thought it was going in/out of park, but the blindspot error I don’t know. Probably tied into a module somewhere?

Before firing the parts cannon, get your battery bench load tested at a local auto part store. Strange things happen, when the battery is starting to fail.

I was using my scanner on my truck without a battery tender hooked up, and my scanning work went well past an hour of time, and things similar to what you stated started happening. My battery got depleted during my scanning activities, and these strange thing started happening.

Might have to do this. Battery is only 1.5 years old but partially wouldn't be surprised if it ended up being a battery issue. Haven't had any other issues electrically, though...

It would make sense given I ran my car for about 3-4 minutes and maybe the battery charged enough to fix the fault(s). It was about 6pm when I last ran the car and 11am when I started it again.

Well if your trips are short, the battery won't fully charge. Get it out on the road.

I saw similar problems at one point. Also kept getting various inconsistent diagnostic codes. Shop eventually figured it out. Abs/brake control module was missing a plastic retaining tab, and module could wiggle too much. $700 for knowing where to place 2 zip ties. So, check your codes and ensure related modules are firmly attached.

Ha, I drove 4,000 miles in June and generally average 2-3k a month. I hope me not driving enough is not an issue

Turns out I threw a code. It was masked by my cat codes which I haven’t done anything with since I don’t have emissions…

P0700 and P182E. Haven’t had an issue since the incident but I cleared them
