2. Brakes
What's wrong, in plain English: Anything that slows the car down. Treat brake recalls as urgent. The amount of vacuum created by the vacuum pump may decrease over time.
What could happen: As the vacuum level drops, the brake assist decreases, increasing braking effort, extending the distance required to stop the vehicle, thereby increasing the risk of a crash.
The fix: GM will notify owners, and dealers will reprogram the Electronic Brake Control Module, free of charge. The recall began October 8, 2019. Owners may contact Chevrolet customer service at 1-800-630-2438, Cadillac customer service at 1-800-458-8006 or GMC customer service at 1-800-462-8782. GM's number for this recall…

3. Brakes
What's wrong, in plain English: Anything that slows the car down. Treat brake recalls as urgent. 3-liter engine, a 3.08-ratio rear axle and four-wheel drive. If a wheel-speed sensor fails, while the vehicle is traveling between 41 and 60 mph in four-wheel or automatic mode, the Electronic-Brake Control Module (EBCM) software may activate the driveline-protection system.
What could happen: Unintended activation of the driveline-protection system will cause unintended braking on the wheel on the opposite side of the failed sensor, causing the vehicle to pull to one side unexpectedly, increasing the risk of a crash.
The fix: GM will notify owners, and dealers will reprogram the EBCM, free of charge. The recall began December 11, 2019. Owners may contact Chevrolet customer service at 1-800-630-2438 or GMC customer service at 1-800-462-8782. GM's number for this recall is N192261050.

REVERSING FROM A PARKING SPOT AND BRAKE PEDALS WERE AS HARD AS A ROCK. I HAD TO PUSH EXTRA HARD ON THE PEDALS TO STOP THE VEHICLE. VEHICLE ONLY HAS 33,000 MILES ON IT. BRAKE ASSIST LIGHT COMES IN TO DASH NOTIFICATION FOR A SECOND THEN GOES AWAY AND BRAKES RETURN TO NORMAL. THIS HAS HAPPENED 3 TIMES IN THE PAST 3 DAYS SINCE WE BOUGHT THE VEHICLE.
