Same issue just suddenly popped up on my 2019 Silverado RST. Just the day before I showed 80%F & 90%R. Truck has 21k mi. and vehicles has never towed a thing. Had recall completed long ago. GM really should be shamed that this problem showed up in the first place and the recall obviously was a stop gap to later drive a $1200.00 brake job, sensor programming. Really??? I know people who put 20k mi on in a year. That would be an unreasonable cost of ownership. My 2010 never had such issues and the rear brakes on that last 60k mi.!!! Has anyone found an actual solution that doesn’t require tossing out perfectly good brakes as I don’t trust my selling dealer to be honest.
