Hey guys, i too have had this problem. Today is the first time this happened. I got my 20 XLT back in july. Have about 1,900 miles. I used the remote start to start the car and i went to go sit inside since i was waiting for my brother to come take my spot. After about 8 minutes of idling, all of a sudden i'm startled by chimes and bunch of warning indicators. "check brake system", "antilock brake fault", "hill start assist warning", "hill descent control fault warning", "pre-collision assist not available".
I thought maybe because of the cold weather since i didn't use the truck for a whole 24 hours (i know that's not a big deal at all) but i thought because of the high 20s temp and wind, maybe it caused some funky stuff to the electricals.
So my brother came and i went to move it. Put it in reverse and the car was rolling as if i completely let off my foot. It wasn't accelerating. Just moving as if i completely have my foot off the brake. But i was on the brake pretty hard so i wouldn't crash in the car behind me. I put it in D to inch foward and the car wouldn't move. As if the brake was completely on.
So i was doing the foot dance with the car just to get the truck parked in the driveway because i didn't know what the hell was going on. I shut the car off. Waited about 20 seconds, started it back up and all the chimes and indicator lights were off.
I'm nervous now to use the truck for work tomorrow but i read that people have resolved this issue, at least temporarily by just shutting the truck off, then turning it back on.
But has anyone experienced this WHILE DRIVING? I use the highway a lot and it would totally suck if all of a sudden the brakes don't work.
My 20 was built in april of 20 so i don't know if it falls under the build date of any recall. Should i try to have the dealer do a software update? I'll most likely call them tomorrow anyway but i would like to hear some suggestions.
Thanks guys.
