Z71NY

I had that second update, and two days later is when it came on.

UPDATE My MIL has stayed off since it turned itself off. I’ve never had any actual symptoms of the codes listed. Dealer referenced this TSB for a fix. We’ll see. https://static.nhtsa.gov/odi/tsbs/2019/MC-10164122-9999.pdf

Add me to the club. 19 Silverado Z71 Had oil change and brake reprogram recall done last week. Check engine on today with U0100, U0101, U0146 and P25A2. Check engine now off when I shut it off and started it ten min later.

Great......

My front one occasionally goes out and comes back on randomly later. Haven’t had it looked at yet.

Anyone else having this issue? Dealer couldn’t find anything wrong of course.......

When changing from day to night - I can just tap the +\- button down once, and the dash and infotainment go to the appropriate ‘night’ setting. Doesn’t work the other way around though. I drove for almost an hour and it didn’t change to day mode. Also interesting that it doesn’t happen when just going ‘dark’ for a short time like a tunnel or garage. Mine also seems to only do it when starting the truck. Like if starting it up in the morning after parking it in the dark. If I’m actively driving when the sun goes down, it usually changes over fine.

This same thing happens to my 19 Z71 almost every day. It’s quite frustrating. Dealer has never heard of it happening. I haven’t scheduled an appointment yet for them to troubleshoot.
