Reduced ability to brake my truck almost caused accident.. warning light popped up ABS, brake, traction control with warnings going across dash like brake system failure 62 mph top speed, service trailer brakes. Codes C0021 P0606, & P25A2. Had update for this problem a couple weeks ago and it was suppose to fix this the dealership said over the phone when called today. Never had this problem before.I am pretty sure that update just updates the messaging letting the driver know he or she is about to die. Taking it into dealer later today. Zf TRW integrated brake control (ibc) had early manufacturing issue leaving metal shaving in the units. These shaving would score the walls and damage units, no ones investigating this issue because it would cost GM too much to replace all ibcs in every truck during early stages of the T1 launch. TRW knows of this issue and has piles of these sitting on engineers desks. There needs to be a recall on all early production T1 truck to replace these ibcs. GM has only been replacing these on a case by case bases when someone reports this problem and their VIN number falls within TRW suspected problem dates. By this time its too late and can cause an accidents.

Started the truck up and the check engine light, ABS, brake, traction control lights were all on with a message in the center brake system failure. Limped vehicle to the dealership to have worked on. The braking system is working at about 10%. I am not the only person that this has happened to GM need to recall these trucks and get them fixed before someone dies

- Newton, IA, USA

I was backing up at a rate of 15 mph when a message flashed on my dashboard saying something along the lines of unsafe to drive over 62 mph, brake failure, electronic control system malfunction. I hit my brakes and nothing. I kept driving backwards. I couldn't stop until the truck came to a stop on it's own. I turned off the truck and turned it back on with a message saying 'see dealer braking system malfunction.' I was at a storage unit, leaving my unit.

On 1/10/20, I was driving home on a major freeway. Just before 5:00 pm I hit traffic and slowed down to roughly 5-10 mph. At that moment my dashboard lit up and a notification stating, "brake system failure" and "service ESC" popped up on my dash. At that point I was unable to stop when applying my brakes. Luckily I had a large enough space between my truck and the car in front of me as well as the two lanes beside me having an opening and I was able to get over and coast to a complete stop on the shoulder. Extremely dangerous electronic malfunction. Had I lost my brakes 10 second sooner I would have been unable to stop and caused a potentially fatal car accident.

- Houston, TX, USA

Started to drive my vehicle and the braking system was nearly gone. Brake pedal was all the way to the floor and the truck had to slow to a stop. Thankfully I was in a parking lot and not on the road because it would have put my well-being at risk align with others. GM should be forced to recall all of the vehicles with this problem!!! how can anyone be allowed to sell a vehicle that will not properly stop when the brakes are applied?

- Muskego, WI, USA

Service ABS, service ESC, and "brake failure 62mph speed limited" lights come on and brake pedal goes to the floor with very very limited braking. Recall for brake control module reprogramming was completed on 1/03/20. Drove truck 1.5 limes and lights came back on and brake pedal went to the floor, steering also became stiff. This was always while driving the vehicle. Has happened on 4 different occasions

Service ESC, service trailer braking system, brake system failure 62mph top speed and a check engine light. Have another appointment at dealer after recall for ESC brake module has been performed

- Forest Hill, MD, USA

The ESC light has come on and it becomes dangerously difficult to stop and/or steer. This is the 2nd time in one week. I brought it to the dealership after the first issue and was told it was all set. The day after I got the truck back, it's happening again. The check engine light now remains on and I'm waiting for a service appointment....again!!

- Forestdale, MA, USA

Took truck in for recall to reprogram brake system software informed I have one of the 'few' trucks that will no accept update and apparently working to find solution

- Bloomington, MN, USA

So, I took it in 12/17/19 for oil change, etc. There was 3 recalls and picked the truck up 12/18/19. 12/19/19 at 6 pm the truck wouldn't stop! I took it on 12/19/19 and they looked into it. They reinstalled the software, and drove it longer to check it out. I picked it up yesterday, after being told it's good to go. Well, it happened again this morning!

- Henrico, VA, USA

I took it Tuesday 12/17/19 in for an oil change at 4K miles to get under 7K service. For my 2019 high country. As I was notified I was due for an oil change. I looked on onstar. Saw there was a recall and figured they could two things at once. Come to find out there were three recalls. Which I get it, things happen. I get it home Tuesday night no issues. Thursday 12/19/19 around 6 pm, as I was backing out of my driveway and it wouldn't stop. I had to stand on the brakes. I am 6'2' and 300 lbs. I was able to get the vehicle in drive and again, the vehicle was not easily stopping. I had numerous dashboard displays. I took pictures of the displayed items. I called rick hendrick Chevrolet at 6:53 pm on 12/19/19 and since I live close dropped it off at the dealer, as I was headed out of town Sunday and wanted this fixed. So.... here comes the issue besides it not stopping that I am even more fired up about! the service guy, called me Friday morning to say they can't find anything wrong. Now, with the display saying service ESC, trailer brake system, and brake system failure not to go above 62 mph, I am pretty sure it triggered an code and would be in code history. I told him I had pictures of the dash display and that they needed to check the code history. He told me at one point it was the vacuum, but then told me that the vacuum was an issue with last years model. And that he was having his master technician look at it. Around 4 pm on Friday, with a family trip coming up Sunday 12/22/19 and not hearing anything I called a few times to find out if I needed to rent a car or they could get me a loaner. I got a call around 5:13 pm on 12/19/19 telling me it's ready and they reinstalled the software and the master technician drove it. Said he is comfortable. I was scared then and scared now to put them back in that vehicle.

Weird brake and steering feel while driving. Speed did not exceed 35 mph in neighborhood driving. Dic read: Brake system failure max speed 62 mph service ESC trailer brake system failure. Brake pedal was hard to push and unresponsive at times. Felt like we were dragging the back end at times. Steering was inconsistent. Parking brake was off. Stopped and started 3 times, reset the vehicle a few times. Prior to a big downhill, the last restart cleared the issue and the brake pedal went to the floor. Drove home and parked. To be honest, felt unsafe to drive especially with my son and wife in the car. Luckily we only had a short 3 miles home. Check engine light on onstar report received in email

- Lancaster, PA, USA

Had a short 5 mile drive to a restaurant. The truck sat for a few hours. Auto started the truck to warm. After 5-7 minutes I pressed the brake and turned on the truck. It instantly threw 3 codes. Brake system failure. Service trailer brake system. Service ESC. Turned the truck off then back on. No change same codes. Proceeded to get the truck back home when I noticed I had almost no brakes. Next morning after starting the truck I didn't have any code messages but did have service engine light. Truck drove and stopped as it normally did.

- Middletown, DE, USA

Truck is 8 months old, less than 10K miles on it. Steering locked up backing out of my driveway. ESC warnings, and various other electrical warnings. Dealer stated it needs steering column or gear as they saw the codes and do not want me to drive the vehicle. Vehicle has been at dealer since November 1st (45 days and counting) GM has stated part should ship the week of December 30th... even if it goes well this will be 60 days in a row without my truck! definitely should be compensated for this. Roadside assistance was 2 hours late, dealership gave away loaner, then when I got a loaner dealership asked me to bring it back within a week because they sold the loaner... now driving a small SUV instead of my big truck. Hmmmm.

Brand new truck an the back up camera flashes flickers, is terrible to see, backing up.GM says its normal. Not normal especially when the catalog says camera is hd 7", never seen a back up camera be able to flash and flicker when the lights are actuated brakes are on. Means there is a draw in the system. There is tinterference with it and the electrical system. I also have the traction control relay clicking everytime the traction control comes on. Have had three vehicles and never heard that to be normal. Head lights are so dim the cars behind me brighten the road. These lights dont even light the refelctors on the road. But apparently normal you can put led in, but have to pay for it. Just keep driving and cant see where your going until you get hurt. Also add led and void your warranty.

Was making a left-hand turn at an intersection I hit a rough patch and truck bounced and pulled a little. When I came to a stop the following lights came on ESC light traction control light as well as a steering one.

The contact called onstar and was informed that codes: 925A2, P0606, and C0021 regarding the ECM, charging system, air bags, and transmission were detected. The vehicle was taken to gilbert Chevrolet (3550 us-441, okeechobee, fl 34974, (863) 261-8947), but was not diagnosed or repaired. The failure mileage was 423.
