Exterior locks quit working?

[Duraburb22]

2022 RST Suburban diesel. Picked up in mid February, now has 16K miles. Last week the exterior locks on door handles quit working when trying to unlock vehicle. They still work to lock however. Also the rear lift gate won’t open when passing foot under rear bumper. Any ideas as to what is going on or do I need a trip to the dealer? Thanks

Both fobs??

Yes-both fobs. I read owner’s manual last night and found that external locks can be disabled. Followed procedure to activate and now it works again! Not sure how it got deactivated but glad it’s working again.

Ours did the same thing when it was new. Exterior buttons worked great for a month and then out of the blue stopped working. Stopped in at a chevy dealer and a salesguy walked me through the settings and sure enough the external locks were off. Turned em back on and have worked fine ever since

Still think there are bugs in the software of these vehicles!!!

I agree. Door locks are working fine. Rear lift gate worked once since I reset and hasn’t worked since.
