2020 Frozen Parking Sensors

[ShamrockShooter]

6 inches of snow today, went to leave work in my 2020 trail boss and front parking sensors went nuts. No snow on front bumper but maybe a little bit of ice melt that refroze. What is really weird is I turned them off with the button but it would not let me turn them back on. It was as if the system locked itself out.

 

I had this same issue once with my 2019 trail boss last spring when I first got it and they did a software update then it got warm for spring so never happened again. Then GM bought it back for other issues and gave me a 2020.

 

I would assume that my 2020 would have had the software update from last spring. Anyone else have this issue and a fix? I know this was a common problem with the 19s.

My 2014 Denali did this whenever the sensors got wet & froze. My 2020 2500HD also does the same.

My 2020 AT4 was doing it this morning until my truck warmed up. No snow on them, just covered in some ice.

We had 10 inches in Michigan and mine were driving me crazy this morning.  Can't wash it, supposed to be 7 degrees tonight.  I wonder why they can not build little electric heaters in them.

Meanwhile everyone in Texas and Florida are laughing at our iced up sensor problems. Glad to know it's not just me. I guess I'll just have to hit the parking sensor button right after I hit the autostop off button all winter.

Welcome to why these sensors are more of a hassle then help in northern winter climates. No they will have no fix for it and every time you get snowy weather they will go bonkers and end up shutting off.

My front collision sensors were going crazy with the cold/snow/ice today. Had to turn it off as it thought I was going to crash every few minutes

I consider this a hazard front camera display stays on while driving sit vibrates continuously and reverse camera sensor show red arrow the whole time it’s being used

The hazard is the driver not cleaning their car.  Get out and wipe the sensors.  

[slj2008]

wipe they down with Rain-x , or Alcohol

Turn sensors off and park in garage or pole barn to thaw.

I had this happen on Christmas Eve when it was 6 degrees and snowing.  Got a thin film on ice on the sensors, place my hot finger over them and rubbed it off and then all was good.  Did it again the next day but went away after a bit probably because it warmed up above freezing.

2020 Silverado LTX, cleaned off the snow and still going off, then ran it through a car wash and it's still going off. Truck is 2 years old and never had this issue until now.
