The Electronic Steering assist stopped working while I was driving to work. Was leaving a stop sign and steering wheel became stuff and notifications on dash appeared. Was able to get to side of the road and turned vehicle off for 20-30 mins and started back up and steering was normal. Notifications on the dash were: Service Power Steering and Service Trailer Braking System. Search online showed this is a known issue that has happened with these vehicles for years and clearly hasnt been addressed. This is very dangerous. Vehicle has 42k miles on it. I had the "Service Trailer Braking System" notification come on a couple times previously and steering felt "sloppy" but immediately went away. And Ive never used the trailer braking system so I didnt think anything of it.

While driving 55+mph on a parkway the service parking brake, check engine light and the traction control light came on with a warning "Engine Power Reduced" which was dangerous because I could not accelerate and there was not a spot to pull over. This is frustrating due to the fact that I was having this same issue 6 months ago and Chevrolet said it was a wiring issue and it wasn't covered by the warranty because it had 42k miles. Chevrolet said it was a known issue but it was not at the level of a recall and it cost $1800 to fix.

While driving on the interstate, my entire display panel/information queue lit up and my information display issued crazy and bizarre warnings. When this happened (I was traveling around 60 mph) immediately pulled off on an exit only to find that my brakes were out/nonexistent and my emergency break button not responding. Luckily and by the grace of God, there were no other vehicles or pedestrians in my line of travel on this exit, the exit fortunately happened to be on an uphill incline/climb which aided in slowing my truck to slow down to a complete stop, and neither I or any other person or vehicles were harmed during this incident. Was told by the Jim Ellis Chevrolet of Atlanta Chevrolet Service Manager (who by the way was a great help and resource through all of this) informed that there was a software -??glitch-?? that had caused all this to happen. I never was told of or was informed of any software -??updates-?? nor had any Chevrolet Dealer Service Department updated this software -??glitch-?? when my truck was given to them for all GM mileage-tiered full service recommendations.

While driving brakes failed and codes came on saying brake system failure 43 mph, this problem apparently is a programming issue that will cost over 600 dollars because -??reprogramming-?? isn-??t covered. Brake pads were over 50% life and it is a very dangerous error.

Around 35k miles had an engine lifter fail and needed to be replaced, covered under warranty. 07/2023 - Had front pads/rotors replaced by Chevy dealer and had loud squeaking ever since. Contacted dealer and was told they are new pads so will just need time to break in. Contacted the dealer again in Sept.Oct. 2023 and brought vehicle in for service for noise concern. They informed me the noise is coming from the rear brakes that was reported as 60% life two months prior. They replaced the rear rotors/pads and noise persisted. Brought vehicle back to dealer in December, they performed a serviced but was ineffective. In March 24 started getting some vibrations when stopping. Brought vehicle for servicing, stated there are rust spots on rotors but everything is wearing fine so this will not be covered under warranty. Also that they do not warranty sounds due to pads can have more metallics then others and they cannot determine which ones do not. I looked under forums and GM Pads seem to be a common issue with noise. My truck was perfectly fine before these brake products were installed and I would like GM to be held accountable for there inferior products leading to loud break noises and violent vibrations while braking !

Truck shudders, with varying degrees of vibration, emtek applying brakes. It is especially rough when applying brakes on the highway as it feels like it could lose steering control. Shaking is also very noticeable at slow speeds. Have had rear brakes serviced and problem persists. As of this month, the "service ESC (electronic stability control)" light has come on, along with other faults on the dash. VIN does not indicate unrepaired recalls, but this issue makes the drive feel dangerous

Brake calipers on 3 of 4 wheels are trying to lock up. Only 54000 miles on the truck this should not be an issue. Could KILL someone

About a month ago I noticed some intense shaking in my 2020 Silverado 1500 RST when braking. The shaking is not only felt in the seat and steering wheel, but is also observable in the dash and in the gear shifter. Due to the obvious concern, I made an appointment with the dealer who, after inspection, stated that all 4 rotors were warped due to overheating. I mostly use the truck on the highway, tow a river raft (easily carried by 2 people) on a small trailer 2 times a year (about 70 miles roundtrip), have never used the bed with excess weight, do not ride my brakes when driving, and I live in Alaska where the temperature is cool (high temps rarely exceeding mid 60's). The brake status report on my dash presently shows my original brake pad life to be 83% on the front and 89% on the rear which was inline with the dealer report that the brake pads were still quite thick. These prove that the brakes have not been overused or abused. According to Kaufman and Associates website, "General Motors is recalling over 350,000 2020 Chevrolet Silverado and GM Sierra pick-up trucks due to a fault in the brake system....The issue involved a lack of heat-treatment for the bolts used to attach both the front and rear calipers.....The issue comes down to long-term performance and safety....Untreated bolts run the risk of breaking under loads, and this can result in braking issues, wheel rotation problems, and internal damage to other parts of the truck. These trucks also suffered from brake system control module and premature brake wear issues, and countless owners have reported brake system issues as varied as check engine lights to outright brake failure." According to the local dealer, my VIN isn't included in the recall and they cannot fix it until it is included (or I dish out $2k). It seems obvious that the issue in my truck is the same that led to the recall of the other 350,000 trucks and I simply need my VIN added so that it can be fixed before catastrophic brake failure.

Vehicle is at 67, xxx miles. Vehicle is losing power, check engine light, service 4wd, service esc, service power steering, service parking brake..... the gas pedal has locked on me already with my 3 small children in the truck at highway speeds. GM says it's fine. I have all the work orders where 2 different dealerships have "corrected" these issues under warranty. Go retrieve the vehicle and within a week Vehicle is back acting up. This truck is unsafe to drive on the roadway. I have not been offered a courtesy vehicle to drive while "warranty" work is being done. I am appalled and in fear for my children and my own life with this truck.

The Advanced Trailering system will fail to load, preventing the user from entering the correct vehicle being towed and the entire system screen is blank and won't load. This could be a huge safety concern if the driver cannot select the correct vehicle being towed since the Brake Gain is stored in the Advanced Trailering system and then the incorrect amount of braking force will be applied to the vehicle while it is being driven, which could cause insufficient or excessive braking forces applied to the towed vehicle. This could lead to rear end crashes or Jack-Knifed crashes. The problem is random but repeatable quite frequently and has been confirmed by the Dealer (refer to included GM Bulletin PIT5792 Published on 11/5/2020) GM has been aware of this problem for almost 2 years and has not provided a fix for it. I have had this vehicle in the dealer on at least 3 occasions to fix the problem There is no advanced warning, message or other symptom prior to this problem. The problem started within a month of purchasing the vehicle
