2017 suburban multiple service messages

[tylergetz34]

Today got in our 2017 suburban and started it as normal. Notices service messages for air bag, theft system, TPMS, park assist and maybe another 1 or 2. Back down driveway and notice that all haulage’s are also not working. Shot off and restart and boom issue gone. Go to next stop come out and then same messages and ossies. Drive home, about 10 minutes drive. 8 mins into drive and everything goes back to normal. Shut off in driveway restart and messages return and gauge’s stop working again. Checked battery terminals all are tight. Turn key to just on and no messages appear and gauges work fine. Any ideas?

How old is the battery? And have it tested for load capacity. Otherwise check and clean main grounds.

The battery might have a mfr date on it, but still have it tested.

I would be looking at the battery and testing it. Modern cars need a near perfect battery for the CAN BUS systems to operate properly. The vehicle is a rolling computer system that must be maintained with the proper amount of battery voltage regardless of charging system health. A weak or low state of health battery will give a never ending list of faults.

Check, clean, tighten all grounds.
