STEERING, SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
After leaving my truck parked for a couple of hours over dinner I returned to find error messages stating "Service Power Steering / Drive With Care" and "Service ESC". I also received a notification from OnStar stating "Diagnostic Alert: Service the Antilock Braking System in your 2022 Sierra within 1 day." My power steering was non-functional, nor were any cruise control functions. Repeated stop / start cycles did not clear the errors or regain functionality. After parking overnight everything was functional, and the errors on the DIC were gone. Using a code scanner there were historical codes of U0131 and U0422.

SERVICE BRAKES
Reference GMC PIT5948A : Service Trailer Brake Message with DTC C159C - October 6, 2022. When I connect my trailer that has trailer brakes the system recognizes my trailer and the trailer brakes work until I try to drive. I get an error message "Trailer Brakes Disabled Service Trailer Brake System". This may happen within a few feet or the longest is about a mile. GMC has no fix and the dealer while cooperative didn't/couldn't trouble shoot the problem as the above PIT has no known corrective action. Now I own a truck that has the "Max Trailer Package" that is rated to pull 13000 lbs but has no trailer brakes. I have eliminated my new trailer as the source of the problem by making a Trailer Brake Emulator, see PIT #5509H Diagnostic Tip. The error continues to happen. This puts myself and the public at risk if the trailer is heavily loaded.

AIR BAGS, SEAT BELTS, SEATS
On July 27, 2022 I was driving my 2022 GMC truck on the freeway. I was rear ended by a semi truck and the passenger side was side swiped by the semi. I was driving the truck with my wife and two kids as passengers. The truck was completely totaled. No airbags deployed and the seat belts did not restrain us. All 4 of us were wearing seat belts. Also, the drivers seat completely broke, it looked like it had been completely reclined to a laying position. A police report was made. All 4 of us were taken by ambulance to the hospital. All 4 of us needed medical care. The truck was totaled and towed, the insurance has since taken possession of the truck. There were no warning lights, service lights or any indication that there was anything faulty with the truck. We had just purchased it in February 2022. My safety, as well as the safety of others was put at risk. The semi truck driver stated he was driving 60mph. If this isn't enough for air bags to deploy, I don't know what is. The seat belts also failed to restrain us. The seat belts were completely loose and during the accident failed to secure us. Again, the drivers entire seat completely broke causing severe head, neck and back injuries.

ENGINE
The engine shut off completely at a traffic light and didn’t start when I pressed the gas pedal to move. It has auto start to save gas and normally starts and stops at lights. This time, the car shut off completely, and I had to completely cycle through starting the car. I almost got rear ended because I took my foot off the brake to drive, and then nothing happened when I pressed the gas.

ELECTRICAL SYSTEM, ENGINE, POWER TRAIN
On 05/28/2022 my family was driving my brand new 2022 GMC Sierra 1500 3.0 Diesel at a rate of 60mph. There was suddenly a loud clunk (transmission) after proceeding a little further and getting speed back to 60mph there was a similar “clunk”… the diesel truck then immediately gained several various check engine / sensor lights all over the dash and went into Limp Mode. Speed slowly decreased from 60mph and finally as we were navigating our final left turn to our destination the truck would not accelerate thru an intersection subjecting our entire family to utter danger of oncoming vehicles. As a last ditch effort to save ourselves I put the truck in reverse and was able to reverse about 2mph. Then proceeded to shut the truck down and turn it back on to get out of the intersection, but the truck would not come out of park. Onstar emergency was contacted to call the police as we were in an extremely dangerous situation. This truck nearly caused our entire family to get in a very bad collision. The truck was stuck in the middle of the intersection for over 2 hours. The police even attempted to help getting the truck out of park , but was unsuccessful. The truck was scanned on site and had various codes including C1555 (x4) U0101 (x2) P25A2 U220F Collision assist light Check engine light Service Traction Control Light Service ESC The truck experienced catastrophic failure at only 319 miles. Day 4 of ownership. This vehicle needs to be investigated if it is failing this early on. There also needs to be a manual release for the parking gear. Truck has no way to be placed in neutral upon failure of the transmission relay.

ELECTRICAL SYSTEM, ENGINE
Check engine light came on at 458 miles. Took it in and after an hour they determined it was the ecm. They said it was bad. Now they're on the hunt for one. In the meantime, in a day the truck has started feeling like it's over shifting and then bogging down. 458 miles, really! I'm going to need a loaner for longer than I've had it and still make payments.

EXTERIOR LIGHTING, VISIBILITY/WIPER
While driving on the highway at night during mixed precipitation/icy conditions I noticed I was loosing visibility. I had to pull over on the highway to see if my headlights were on. I discovered they were completely covered in 1.5-2in of ice. The entire front grill of the truck was covered in ice. I had to chip off the ice on the headlights so I could see. I had to pull over three times during my 2hr drive to scrape the lights just so I could see! The headlights on the 22 model have shape, not straight or a smooth curve like prior models, which is part of the problem. Although, it was strange how the entire grill was covered in ice. I have always owned GMC or Chevy trucks and have never had anything like this happen. I wish I took a picture to send in but I didn't think of that in the moment. This is absolutely a safety hazard. I hope in the near future there will be a recall to have this issue addressed.
