STEERING, SERVICE BRAKES, AIR BAGS
I was in an accident on October 20th 2022 while driving home. U had just reached the top of a sharp crest on a two way road. As I started to straighten out the wheels coming out of the turn I noticed my direction was still as if I was turning the wheel. I tried to brake and pressed the brake but it went to the floor and the truck kept going. I collided with the other vehicle and it was a miracle neither of us were seriously injured or killed. We had problem with the steering box about 2 years ago and had to have it towed to the dealership. The other vehicle was a Chevy 2500 with a custom steel flat bed & it slowed me down and I finally came to a stop with the front tires off the road. Neither vehicle alerted onstar & airbags did not deploy. His vehicle miraculously had minimal damage to the cab the majority of the damage was the metal gear box located under the bed in between the cab & tires. It was super scary & left both vehicles disabled.

ENGINE, FUEL/PROPULSION SYSTEM
While Pulling 35' 5th Wheel down freeway, a message appeared in instrument panel telling me the fuel filter was at 0 percent and was going into low power mode. There happend to be an offramp there that I was able to get off the freeway. While making the turn on the offramp the truck died. I pulled over as far as i could whie coasting with no power steering or brakes, leaving truck & trailer partially blocking the offramp. Unable to start the vehicle, I Immediatly contacted Onstar and they dispatched the CHP & tow truck. When CHP arrived he asked when tow truck would be there. Without being able to confirm exactly, and due to safety concerns because of blocking the offramp, he called his own tow truck (Rons Towing) and forced me to move vehicle to safe location. The issue ended up being the injector fuel pump (CP4) that GM was well aware of going out and sending metal fragments throughout the fuel system. I've been told the pump was made in China and not to GM standards. The vehicle has been repaired, all work was covered under extended warrenty, This all could have been avoided if GM would have replaced the faulty fuel pump under recall. Had this happened 100 miles further on our trip we would have been going over Pacheco Pass in Calif. Could have been a total disaster had we been going down the other side with No Power Steering & No Power Brakes pulling a 12,000 lb Trailer in the Dark.

ELECTRICAL SYSTEM
When trying to turn at low speed, the vehicle appear to shut off and the steering wheel violently cuts to the left and then right. I am unable to hold on to the steering wheel for fear of it breaking my wrist. The electrical system seems to completely shut off, as the panel goes black and when it returns, my settings are wiped out and the clock is reset to 12:00. When this happens, I have no control over the vehicle and it is very dangerous to people or property in its way.

ELECTRICAL SYSTEM, UNKNOWN OR OTHER
Electrical component- Dashboard is constantly glitching, blue-tooth will not connect properly, electrical appears to turn off randomly while driving to the point we have to pullover because it appears and feels like the truck is turning off. Power step running boards malfunction- They don't open or close when they are supposed to. Power step running boards also malfunction while driving. It is a risk because we've had to pull over in conditions that aren't safe, putting a family of five in danger. The problem has been reported to the dealership and manufacturer and has gone unresolved.

ELECTRICAL SYSTEM, EXTERIOR LIGHTING, STEERING
While making a quick left hand turn at low speed, steering wheel suddenly locked, all lights and electrical went out and engine died. This left me stuck in a busy intersection with no lights. I was able to restart engine after a minute or so. Error message appeared "roll driver side window up, etc." Needless to say, no longer have confidence driving my truck not knowing when this situation may re-occur.

Once vehicle is put in park, the control panel comes and reads, “shift in park and radio and head lights stays on as well”. I exit the vehicle and it continues to display the mention above. I’ve restarted the vehicle and put it back in park still the “shift in park”, stays on. I exit the vehicle and monitored the vehicle for approximately 5 minutes and finally turned off. This never happened before, I’m afraid it may stay on one of these days and run the battery down.

SERVICE BRAKES
When I initially started the vehicle, I noticed the parking assist would not turn on. No warning lights or messages were displayed so I didn't think much of it and continued on driving. Approximately 5 miles down the road while traveling around 45 mph, I came upon a stoplight with other cars waiting. I pressed the brake to start decelerating and the pedal went all the way to the floor and vehicle did not slow down/decelerate. The check engine light, ESC, trailer brake, and brakes warning lights/messages then illuminated. I was approaching the vehicle in front of me quickly so, to avoid a rear end collision, I swerved into the shoulder and was able to coast through a right turn and on to a side street where I eventually coasted to a stop. I narrowly missed a major collision and was fortunate that there was no cross traffic approaching when I turned on to the side street. This could have been catastrophic, especially if pedestrians had been in the area. After stopping, I restarted the truck and the brakes seemed to work, however, the warning lights remained illuminated. I drove slowly to the nearest dealership. They replaced the electronic brake control module. Truck has approximately 20,000 miles on it and is well maintained.

While operating the vehicle, the radio went to full volume on its own. Attempts to turn it down did not work. The radio turned down, when the buttons on the steering wheel were pressed, but turned back up faster than I could turn it down. The power button on the radio also didn't work. I tried pushing it and then tried pushing and holding it down for a few seconds. I had to end up grabbing my phone and shutting the Bluetooth off on the phone to get it to stop. Very unsafe and distracting. It has been documented in a forum where others have had the issue as well. It is the new infotainment system and appears to be a software bug. Here is a link to a forum where others have had the same issue. https://www.gm-trucks.com/forums/topic/260308-2022-refreshed-sierra-audio-issue-max-volume/

I have owned this GMC Sierra now for 4 weeks. I went to trailer our new boat and trailer with EOH braking system and during my ride home I would a Trailer brakes disabled pop up then finally stayed on and lost all braking to the trailer. Trailer was check and all good then found out that many others with GMC Sierras and Chevy Silverados had had this issue now for the past 3-4 months with GM still not having a solution yet we all have defective and very dangerous vehicles losing all braking with the trailer due to this issue. They need to be pressured to get this fix ASAP before someone dies. Here is the forum with many others complaining about this issue. https://www.gm-trucks.com/forums/topic/260521-2022-silverado-faulty-trailer-brake-controller-and-buggy-camera-when-trailer-connected/
