AIR BAGS
Received notice in March 2021 of defective passenger side air bag inflator which, due to environmental related degradation can explode during deployment sending metal fragments through the air bag into the vehicle risking serious injury or death. Notice further states parts are not currently available to repair the defect. No notice was received as of 9/15/21, and in checking on NHTSA and GM websites on this topic, there is no indication of when or if it will ever be repaired. This complaint is initiated to get specific information how long a passenger in my vehicle is at risk of serious injury or death from this defective air bag inflator.

SUSPENSION, POWER TRAIN, SERVICE BRAKES
I purchased the 2020 Sierra 1500 because the label on the truck frame states that it can tow 9300lbs. Subsequently, in April 2021, I purchased a 34' Travel Trailer with a max capacity of 8995lbs. In August, I received a notice from GMC that they overstated the towing capacity by 500lbs. The new towing capacity is 8800lbs. GMC's response to my request for a refund was that they were not going to help me. Their solution is that I can be provided a new sticker by the dealer upon request. This does not resolve my issue, nor the issue of other Sierra owners who purchased this vehicle because of its stated towing capacity. In doing research, it appears that in model year 2014, GMC faced a class action lawsuit for misrepresenting their capabilities. I believe that this malpractice is a safety concern for me and many others. Attached is the towing label on the frame and the letter from GM.

ENGINE
While driving on the highway my truck started to buck and had a loud engine knocking noise. Speed was greatly reduced so much so that I was going under 45 mph in a posted 65. The check engine light did not come on. While sitting on the side of the highway there was a severe engine knock only when the revs on the engine were increased. Oil pressure and cooling temps were as they should be. The next day on the way to the dealership the engine started knocking. This time the check engine light came on, speed was greatly reduced at this time. After about five miles the knocking stopped and the check engine light went out. The Dealership checked it out and stated the lifters were bad. It seems that this is a known issue with GM. I was told by the Dealership that there were two other trucks ahead of me with the same issue. Also, because this is such a prevalent issue with GM, they cannot keep up with the demand for parts. My Dealership is waiting for a head gasket. GM has known about the faulty parts for approximately two years, and they are only replacing some of the faulty, poorly made parts, hoping the other side of the engine will not develop issues and fail. I feel this is placing the driver and occupants at risk while driving down the highway and not being able to maintain posted speed limits, or just locking up and engine, and coming to an abrupt stop.

STEERING, SERVICE BRAKES, SUSPENSION
The first issue is popping coming from the front end of the vehicle causing a steering issue. This has been "repaired" multiple times with no resolution. Every time the popping occurs which is almost every turn the steering wheel will not turn. The next issue is the radio is causing driver distraction by changing stations and screens not just on the display itself but the instrument cluster as well. The radio has been replaced once due to the fact it was on backorder for 6 months another attempt has not been made. The third issue is the brakes have failed at slow speeds no warning lights were on, they just stopped working in the Mcdonald's drive-through. I had to get out of line to keep from rear-ending the person in front of me. Now, after that experience, the ABS light has come on and the service StabiliTrak flashes on the dash as well as parking assist off, everytime I hit the brakes. .

TIRES:TREAD/BELT
While traveling at 65 mph the vehicle began to Vibrate and suddenly the tread separated and began banging against the side of the vehicle LT265/60R20E. I feel fortunate this was a rear tire and I was able to safely bring the vehicle to a stop. The tires were installed at 35333 miles so they only had about 26000 miles and are rated to 60000 miles.

SUSPENSION
I was driving my 2020 GMC Sierra AT4 at about 15mph on a 2 way city street slowing for a traffic light when my vehicle started to shake violently...at first thinking it was a flat, but the shaking was much different. As I was slowing in anticipation of the light, now at about 5mph, my truck suddenly dropped and stopped. This would have been catastrophic at freeway speeds! I immediately thought maybe someone had tried to steal the wheel overnight as I knew now it was not simply a flat, but knew I had wheels locks and thought that unlikely....this was while I was exiting my now parked truck. I knew the problem was on the front passenger side, and was shocked as I rounded the vehicle from the front only to find the entire front wheel assembly folded flat under my truck. The entire brake assembly was still intact, but the front drive shaft was pulled out, as well as the upper and lower ball joints. The brake hose became severed in this incident.

EXTERIOR LIGHTING
THE HEADLIGHTS ON MY PICK-UP ARE ABSOLUTELY HORRIBLE AND DANGEROUS TO DRIVE WITH. I HAVE EVEN GONE TO THE EXPENSE OF HAVING BRAND NEW ONES INTALLED AND THEY ARE NO DIFFERENT IN THE LIGHTING. I CAN BARELY SEE ONE CAR LENGTH AHEAD OF ME WHEN DRIVING AT NIGHT, WHICH IS PROHIBITING ME FROM USING MY PICK-UP FOR NIGHT TIME DRIVING. THIS IS RIDICULOUS TO HAVE SPENT SUCH A LARGE SUM OF MONEY FOR A VEHICLE AND NOT BE ABLE TO SEE DRIVING AT NIGHT. THERE SHOULD BE A MANDATORY RECALL OF THIS VEHICLE AND THE HEADLIGHT SYSTEM.

ENGINE, FUEL/PROPULSION SYSTEM
The truck has 7500 miles on it and the check engine light keeps coming on then goes back off. It is impossible to schedule service as the light goes off before it gets to dealer. The when driving the truck many times the check engine light will flash for a minute or so and then remain on steady. This is very frustrating and the dealer has found nothing. It has happened probably 10 times since the truck was new and continues now. The truck was just serviced and the dealer found nothing causing this.
