UNKNOWN OR OTHER, VISIBILITY/WIPER
When I drive this car on the free way or on a very windy day, a loud air gap is caused by the front driver and passenger window. It hasn't been inspected by the dealer or anything but I believe there could be something wrong with the quality of glass or the seal that hold the glass. I've also driven with the windows lowered on a windy day and saw the edge of the glass bend. I'm worried it's gonna snap or shatter one day. It's been happening since I bought it but I didn't notice until I drove on the free way.

STRUCTURE:BODY
The passenger door is attached properly, when the truck reach 70 mph or higher and little cross wind, there is really loud noise like the brakes sticking. I was afraid the door might flew off while I'm driving and I have infant in the back. I took the truck in to the dealership where I purchased and the problem was never fixed. when I took the truck back the 2nd time, the dealership told me to take my truck to GM dealership. I took the truck to the GM dealership hour later my truck was ready, apparently this problem happened to another vehicle. Now the noise is worst and it's on both side when I'm driving 70mph or higher with cross wind. I took the truck back to the dealership and now I'm waiting on parts to arrive 2 weeks later no call back. It's been one year 6 months with less than 19000 miles, afraid the doors might pop off and still the problem is not fixed.

FUEL/PROPULSION SYSTEM
My 2020 Silverado HD truck requires a replacement wiring harness and DEF tank and is basically inoperable. This is a known issue for GM and spans multiple model years.GM continued to produce throughout multiple model years knowing that owners may be stranded and unable to use these vehicles because of the defective parts. Hardships for owners would include loss of income and exposure to various dangerous conditions. The DEF tank has a heater system that can get exposed to the DEF fluid because of a poor design and poor manufacturing standards resulting in short circuit. GM will replace the wiring harness and combination tank/heater assembly under warranty. The parts are supposedly on NATIONAL BACK ORDER, yet GM continues to manufacture and ship new 2022 models with the required parts needed for repairs. GM will not provide alternate transportation. Supposedly in excess of ten thousand trucks are affected. Warm climate owners and warm temperatures may affect this issue positively. GM has no policy for a timely response to this issue. Trucks will become unsafe to operate when the electronic controls limit the truck speed to 5 mph or less. An operator may become stranded and exposed to dangerous highway conditions if stranded with this issue.

FUEL/PROPULSION SYSTEM, ENGINE
The DEF heater/tank shorted out. The DEF system has thrown a code 3 times in the little over a year I’ve owned the truck. This final time I was told that the tank needs to be replaced. The truck has now been in the shop for 2 months and there is still no ship date on the replacement tank. The tanks are on a national back order. From what I understand there are about 9,000 people waiting for this DEF tank countrywide. I now have a $60k work truck that I am paying for but cannot use with no reasonable end in sight.

POWER TRAIN
Vehicle developed a sensation at approximately 28,000 miles similar to driving over a rumble strip. At approximately 32,000 miles this was diagnosed as a failing torque convertor. There are TSBs related to this for the 8 speed transmission, but dealer stated no known TSBs exist for the 6 speed. The truck is currently in the shop getting the torque convertor replaced and should be available for pick-up in the upcoming week. Rumble strip sensation occurred under light throttle acceleration and presented more frequently on an incline. There were occurrences on flat ground, but this was not as common. The vibration occurred most often at highway speeds of around 70 MPH, but also occurred several times in the ranges of 20-30 and 40-50 MPH. Tachometer reading during these occurrences was around 1,500 - 2,000 RPM. Issue was intermittent and would come and go. Most of the time the sensation was mild, but periodically the vibration would be severe enough the driver felt like he had been rear-ended. A separate symptom would occur while going up hills and the tachometer would bounce up and down approximately 300 RPMs with a noticeable surging sensation. When presenting, the vehicle would surge forward every few seconds until the hill had been crested. This only occurred at highway speeds with cruise set and would not present when the rumble strip vibration was present.

POWER TRAIN, ENGINE
I was driving down I27 10 miles south of Lubbock when my 2020 Silverado 1500 3.0 Diesel engine stopped accelerating. I was going 75 miles per hour and the truck just stopped causing trauma for me and my family we were lucky enough to get to the side of the road. I ended up calling gm roadside assistance and they sent a tow truck to pick us and the truck up. The truck wouldn't engage into drive nor reverse. Once towed to the dealership, Gene Messer Chevrolet, in Lubbock, Texas, a service tech mentioned that a ton of the lifters bending push rods are going out on the late 2019, 2020 model silverado due to cheaper lifters added to the vehicles due to Covid shortage supplies. In essence, they wanted to get these models out with no regard to safety of the consumer. I'm not pleased with the craftsmanship GM has lined out on these trucks, this could've ended way worst. They jeopardized my families safety for profits. Right now the truck is still awaiting diagnostics still won't drive nor reverse per dealer service tech. It's just a terrible situation, the truck is new only has 25,500 miles on it, this needs to be recalled.

POWER TRAIN, VEHICLE SPEED CONTROL, ENGINE
Upon starting the vehicle for the second time one day, when placing the automatic transmission into 'D' - Drive, it began to roll backwards as if it was in Neutral on a slight decline and the brakes had to be applied to avoid rolling downhill backwards. After attempting to place it back into 'P' - Park and back into 'D' - Drive and attempting to try 'R' Reverse to try to get it to move forward properly, it would not go forward. After several tries and restarting the vehicle completely, it finally attempted to move forward but would only do so at a reduced speed and would not respond to the accelerator pedal beyond a certain amount. After trying again, it appeared to move forward a bit better, but then upon stopping at a stoplight and attempting to pull out for a left turn onto the road, the speed again was reduced and I had to immediately place it into 'R' - Reverse to avoid an accident due to oncoming traffic. Finally I was able to get it to move forward a bit better and was heading directly for the dealership but since the power just was not getting to the wheels (transmission?) I pulled over and shut off the truck for a few minutes. Upon starting the truck again, it seemed to move forward better after that but had the 'check engine light' illuminated. The truck is at the dealership now, they have had it nearly a week and said they will not begin to look at it for another week at least since they only have 2 technicians who can look at it.

SERVICE BRAKES
My 2020 Trail Boss recently had a break fail on the front right. The brakes are metal to metal and the brake sensor is reading 54% brake life left. GM says that there is only one brake sensor on the front of the truck and its on the right hand side. When I spoke to Chevy customer service I was told they have received several calls regarding this matter. Chevy service department is saying there is nothing wrong with any of the equipment, but I find it hard to believe that brakes wear this way normally. If they did I would think Chevy would have 2 brake sensors for each wheel.
