2021 Blazer electric parking brake problem
I am intermittently discovering the electric parking brake set on vehicle start up. The manual states the vehicle is supposed to do some random checks of setting the parking brake but this appears to be happening way too often. I've had it happen on 3 out 4 starts in a 3 hour period, sometimes 4 times in a day, sometimes 5 days with nothing and then several times again. It is rare, but I have occasionally heard the brake operate and set when I walk up to the vehicle with the remote in my pocket and
several times have heard it set when I press the button on the door handle to unlock the car. However, those instances are very infrequent. Dealer is unable to find or duplicate a failure and just refers me to statement in manual. I just think it happens way to frequently to be a "random operation check". Any one else having this problem or know a solution ???? |
Same issue

Due to the way newer vehicles are there really is no way to know whats going on with it, could be software within the computer(s) or a faulty computer all together, not much to be done i think.

how did you "turn brake off" , pull a fuse ? I assume turning it off did not cause any other issue ?

This is one of the reasons I like having a 18 year old Blazer with manual parking brakes.

Update on Parking brake problem
Just an update on status. Dealership has been unable to resolve problem and pretty much given up. The GM Phone Line has not been very helpful - basically says they will "facillitate" but it is the Dealership that has the Techs to fix the problem. The Dealership says their Techs are stumped and they need Factory/Engineer/Corporate help. Both sides pointing at each other and nothing happens. Interestingly though, since the weather has gotten colder from November to mid-January the intermittent problem frequency has greatly decreased. Since it dropped below 20 def F for several days, it has not happened at all ! I obtained the vehicle in February and didn't start noticing
the annoying frequency until mid-April. Bottom line, it appears the problem is ambient temperature related...... |

My 2021 Blazer also randomly sets the ebrake on it's own. This is a safety issue that should result in a recall. Don't know how many times I've hopped in, started the vehicle, put it in reverse, gave it the gas and then find out the ebrake is set even though I never set it! I usually have to gun it before I realize the ebrake is on!
Every time it does this it also shuts off my cruise control! |
