2022 GMC Sierra service brakes problems

“My truck has the same issues for the transmission and engine problems I have taken it to 4 dealerships and they all say the same thing. The first one I spent about 3 hours there and they changed the 20 oil to the 40 oil and said that will fix the issues but it hasn't i called GMC to report this and they sent me to the others but they said it's been looked at and I know one of them didn't do anything to see the issue.Gmc called the other day and I told them I will let the engine locked up or the transmission keep doing the same thing and they'll have to fix the issue then.I do have 109000 miles on it but thus issue has been going on for 4 years they said I have 150000 miles for the issue but I do t think that is right.I paid them cash money for the truck when I bought it”

“Truck did not stop when applying brakes. Message displayed brake system failure and the breaks were spongy. The truck was towed to the dealer and required the master cylinder, gasket, and reservoir to be replaced with 23,403 miles. This appears to be an ongoing issue with GMC Sierra trucks and needs further investigation as this potential could be catastrophic. Also, as this appears to be an ongoing issue, owners should not be responsible for the cost associated with any repairs and should require an immediate recall.”

“Engine failed at high speeds on interstate. When my Truck shut off the steering and braking system went out and getting to shoulder of interstate was difficult with others around me. Express lanes were limited on emergency shoulder therefore my truck was partially on the high speed driving lane. 911 was called out to block freeway lane. Check engine light blinked right when truck shut down.”

“1.)When driving the vehicle it will randomly shutoff while driving with loss of brakes and steering until it will randomly turn back on.The vehicle experiences intermittent electronic and drivability malfunctions. The issue appears to involve one or more vehicle control modules and/or electronic systems. At times, warning lights and system messages appear, and vehicle performance is affected. The vehicle is available for inspection upon request. 2.)These failures create a serious safety risk because they occur without warning while driving. The vehicle may lose normal functionality, display multiple warnings, or behave unpredictably. If this occurs in traffic, at speed, or while maneuvering, it could increase the risk of a crash or leave the vehicle stranded in an unsafe location. Furthermore on 3 separate circumstances I came close to crashing the vehicle putting at risk lives in the vehicle and outside. 3.)The problem is intermittent and has been difficult to reproduce on demand. I have taken the truck to the dealership multiple times. The dealership has stated that because the issue is not actively occurring when they have the vehicle, they have been unable…”

“Recently, I just purchased my vehicle from Wally Edgar Chervolet with no open recalls on the vehicle. As of September 29th, 2025 for my very first oil change on the vehicle I was made aware for 4 OPEN Recalls which was told to me at the time of purchase. The dealership closed the all recalls without actually checking my make the vehicle was safe to drive. The Recall Numbers are: N252510321, N222362040, N212356230, N222357620.”

“Below 10,000 miles my truck had the master brake cylinder to put which they repaired under warranty. At about 89,000 miles the engine went out stating a misfire on cylinder 2. After talking with GM the vehicle needed all the rods and cam shaft replaced which was almost an $11k repair of which I had to pay almost $5k. The truck still has sporadic shakes while at idle. Many other owners have complained of the same issues. It’s hard to understand that a new truck would have so many issues. The truck was also sold without the chip to heat the seats or the heated steering wheel. These were down afterwards one of them about a year after purchase. We feel GMC should have paid for this repair given all their engine issues. They changed the warranty from 100k miles to 60k miles because they knew these engines have major issues.”
