Radio clock and seat memory keeps reseting

[fatmonk8]

Hey all,

I have a 2015 Tahoe and every so often the clock on my radio and the seat memory keeps reseting on startup.

Google said it may be the ignition switch but it is a push to start so I'm not sure that would apply.

Any ideas? Maybe a battery issue?

How is the battery life? I would have it tested to confirm the state of health.

I plan on getting it tested today. Wasn't sure if a bad battery would cause that issue or not.

does the HVAC reset also? or just the seat memory and radio?
seat memory should not be battery related as the setting should be permanent unless changed to a different setting, but I could be wrong
does the seat memory just go to some default? or does it change to something else entirely different than what it was? or only partly different?

It seems to change to some else entirely, like the seat will auto recall to a different position and the steering wheel will do that same. I have to reset the seat position and save it again after every time it "resets".

to me that sounds more like a internal short is occurring perhaps in the memory module but I am not sure how it is related to the radio resetting, If the hvac is not defaulting to I think 74? or 73? then it is most likely not the battery

I have not paid much attention to the hvac. I'll make sure to look at it if it happens again.

Autozone said the battery is good

That's all I really have regarding this problem. Another suggestion will be to remove and clean the ground wire on the passenger front side frame behind the felted wheel liner. There is a grounding connection that uses a self tapping bolt into the frame there.

So the issue had not happened for a while as I just let the radio clock be off and never bothered to reset it. Hadn't happened again for a while.

The other day I decided to reset the clock again, and wouldn't you know it reset again. But this time it didn't mess with the seats.

Maybe the seat memory was being caused by something else entirely.

Have you checked for a loose or corroded ground?

Yes, couldn't see anything obvious.

Using same key fob each time it happens? 2 diff key fobs can be set so that when you enter the truck it changes the seat… not sure about the radio or click stuff tho

Yes I'm aware of the two fobs with different memory settings, and yes the issue occurs all with the same fob.

Hmm ok then. i wouldn’t trust autozone btw.

I don't, but it's hard to screw up checking a battery. I even went ahead and bought a battery jump pack with a tester for myself and the battery is fine as far as I can tell.

I think their battery testing equipment is correct. Take it to a competitor for a second opinion. I had issues years ago that weren't battery related, although I received the recommendation of replacing an only 1 year old battery at the time. I went to Autozone, Advance and O'reilly's. I figured if all 3 of their scan tools proved correct that its not the problem (and wasn't)

When you get a battery load tested they should give you a printout with the battery specs and the results.

Ah, well this they did not do. But still, I bought a jump pack with a battery tester and it tested fine.
