Service Brake assist is illuminated, Brake Failure has occured. Near miss on Busy street leaving parking lot.

- Joplin, MO, USA

Brake pad monitor listed over 90% for both front and rear brakes then all of sudden I get warning light that says Service Brake Monitor. I have had this happen twice since I purchased this vehicle new. The dealership has fixed it twice, there were software bugs. I cannot tell when I have a real issue or is it just a software bug.

When driving my truck I lost all power steering got notifications to service abs in 7 days, service esp, and service power steering as well as a stability at light being on. Could no control my vehicle, restarted the truck 4 times, and it disappeared, garage could not pull any codes. This is VERY unsafe!!!!!! And has been issued a recall in past models and years. I could have been killed, for a problem the GM is aware of and have not issued a recall yet.

When I began to accelerate my vehicle the brakes locked automatically. I noticed that once I hit 6 mph the brakes locked. I tried troubleshooting by turning the truck on and off, turning off all of the assistance buttons, turned the parking brake on and off. I was able to drive it in reverse.

Last Weekend was taking the kids and my brother and his son fishing, so 2 adults in front seats 3 kids on the backseat. Got my boat all hooked up and we're off. About 2 miles down the road the truck rebs up really high and then bottoms down hard on the RPM's. As soon as this happens all lights and instrument cluster goes crazy. Check Engine light on, Parking Brake Light On, Traction Control Light On, And I'm sure I'm forgetting more. The Cluster states ESC failure drive with caution, Do Not Exceed 43 miles per hour speed limit Brake Failure and So on. I have since found pictures pf the exact same thing that happened to me that morning and will provide. Needless to say I have no brakes and have a 19 ft bass boat behind me. All I could do was let off gas completely and push brake pedal all the way to the floor and pray that it stopped. Good Lord willing it did. Pulled over asap and killed truck, let sit a few minutes while I assessed the situation and cranked it back up. All lights and brakes were fine. Has not done it since but I only drove to dealership to find out the issue and 4 days later still no answer. Its a 2019 with only 26000 miles, and has never had 1 issue before this

While driving on a two lane road I proceeded to pass a slow moving vehicle, after accelerating from 45 MPH to 60 MPH my Check Engine light, Service Electronic Stability Control (ESC) and Service Electronic Brake System lights illuminated on my display. My RPMs increased before shifting gears and I noticed a significant loss in power. Thankfully there was not an accident when the incident occurred; however, if an oncoming vehicle or bad weather it could have been a different outcome. I took my vehicle to a GMC dealer to diagnose the issue where I found out my lifters for my valves are bad and my fourth cylinder is inoperable along with a bad CAM. A new vehicle at 65K miles on it should not be having mechanical issues that can pose a danger while driving, putting others and my safety at risk. GM needs to reevaluate the products and materials their using to build engines to ensure there are no flaws starting with the valve lifters.

Vehicle had the "Service ESC" warning come one along with the warning of brake failure do no exceed 43 miles per hour. Called the dealer to discuss options and was told that I could not get in for 1 month..... For a critical failure and known issue this is unfathomable.

Vehicle was 300 miles out of warranty when I get a service trailer brake warning on my info center replaced a blown fuse and the fuse blows again, no trailer has ever been hooked up to this truck. Went online and inquired about this problem and there's thousands of post and complaints about this problem, even on a GM site there's a PI investigation about this problem, why doesn't GM just do a recall to fix a problem they know about. I'm getting ready to buy a travel trailer and now I don't know if its safe to pull it!
