Strange braking issue

[condor767]

Ok guys this really threw me for a loop.

2019 Bighorn, brand new, 1500 miles. Day 1 of a road trip through the Virginia mountains, nighttime, enjoying my awesome bright LEDs on high beams. Spot a deer just in time, had to nail the brakes and luckily avoided him.
Right after I drove by him, after the aggressive braking, I get a “Service Electronic Stability Control” message along with the amber car skidding light on the dash. Followed shortly by the red BRAKE ON light (parking brake set?).
As I’m pulling over to troubleshoot, my brake pedal feels terrible! Almost as if the ABS is constantly kicking in, tons of vibration through the pedal and questionable braking performance.
Ok, no need to panic. I get it stopped, cycle the parking brake... nothing.
Executive decision time.. I shut off the truck completely and open the door. Close it again and restart the truck. Note, the brake pedal is extremely stiff, takes quite a bit of pressure on it to push it enough to allow the starter to engage. It starts, all the warning lights go out and the brakes work perfectly for the rest of the drive. Problem solved?

Any ideas? This all happened right after the aggressive braking to avoid the deer. Gremlins in the electronics? Dealer visit required?
Thanks for any suggestions.

Brakes are something you don't really want to mess with, especially something this new. Being that dash warning lights lit up, the dealer should be able to to read stored error codes. If anything it will be on record if you have problems down the road.

Thanks, that’s what I was thinking too. Will give them a call and keep y’all posted.

I think that's a good call. Get it checked and recorded.

Just drove back. Check engine light on the whole way now. Dealer appointment at 7am tomorrow will post what the results are. Truck performed flawlessly despite the issues.

Update. Took it to dealer this am. They pulled the stored codes... looks like a bad brake booster. New one ordered under factory warranty.

Didn’t think this would happen with a brand new truck but I guess it’s a remote possibility. Glad it’s getting taken care of
