There has been a recall on the 2020 sierra 1500 for the driveshaft which causes shuddering and vibration which my vehicle is exibiting but my vin is not on the recall list
- Miami, FL, USA
My truck 2020 gmc sierra 1500 AT4 denali is not working properly since July 2024. I took it to 2 different dealership to get a diagnostic and i finally ended doing the repairs for brake issues. I have been towed 6 or more times and almost experienced 2 car accidents since I drive the truck after the supposedly repairs where done but i ended stranded again with no brakes. The dealership has repair the truck 3 times but im still getting sevaral codes the fact that i had to pay out of pocket and have to deal with this and expose myself to danger and my family in driving a vehicle that is no safety condition its absurd. I call several times the recall GM hotline and i was told GMC 1500 are included in the recalls just not the AT4 and i have a family member with the same truck and same issues she ended up trading in the truck recently since she kept experiencing the same issues over and over again just like me.

The rear sliding window leaks water inside the cab every time it rains. With water getting into the cab the issue of mold has begun and that could be a serious factor to any children or adults that ride inside the cab of the truck. There is also rust issues that are notable under the rear seats of the vehicle. Water inside the cab can also interact negatively with any electrical components of the vehicle. I tried to get ahold of the dealer and they always say they don't have time to get my truck in. I have read that this has happened to other vehicles that are the same year and model and they just fix it with caulk which does not seem appropriate for a almost new vehicle. The vehicle has not been inspected. There were no warning lamps prior to this issue. A possible symptom was that my back up camera stopped working for a day right after a rain.

Rear window leak causing whole inside back to get soaked. Have paid hundreds of dollars to have sealed didn-??t work. New window didn-??t work it still leaks. It-??s going to cause interior to mold and body to rust. Dealership and glass business both say it-??s body issue and they have seen many GMC and Chevrolets with this issue. Google show 1000s with same problem.

Rear Window Leaks due to failed sealing at the factory. If not fixed will ruin interior components and possibly rust. Yes No
- Jerome, ID, USA
The rear window was leaking a substantial amount of water soaking the back seat. Had the service bulletin done, which did not work. Then under further inspection found cracks in the rear power window track. Dealer told me GM would not cover replacement because it was out of the 3 year warranty. Then was told it would cost me 1200 dollars to replace. GM should cover this because it will lead to black mold.

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.

Rear window (the one that faces straight back towards bed of truck) is leaking-?? Haven-??t taken it in to dealership for repair because I-??ve exceeded mileage so truck is no longer under warranty-?? Not sure how long it-??s been leaking but I-??ve recently noticed that water stains (runs) on the inside of this window after rains, washes, etc-??

Vehicle engine went out on truck.

It was fine and we drove to our neighbor, parked about 15 mins. When we started the truck to turn back, the steering was super heavy, with 2 messages pop up on the dashboard: Services ESC, and service power steering drive with care. Tried several times to re-start the truck, it's keep the same. In our neiborhood, parrot tulip view, pflugerville, tx 78660. Raining all night, not sure if it's related to the weather.

When stationary and preparing to start vehicle intermittently see "service steering column lock" message appears and disappear once vehicle is started. This was previously supposed to be addressed with service bulletin 20-na-21 however being told by service department that vehicle has all current updates applied a year ago, including the one that should of addressed the issue. Told that the vehicle history shows records of past "loss of communication to dic" but as they can't immediately reproduce no action was taken.

Dangerous visibility hazard when backing up vehicle at night. Infotainment screen switches to "full brightness" when backup camera is activated, resulting in blinding light to driver. Driver can not backup safely without physically covering the screen to regain visibility. Screen brightness reflects off all 4 windows, windshield and back glass. Side mirrors are unusable in this condition. There was a fix for this issue on previous GM models, (prior to 2018), however no fix for 2019 - present

Navigation states to turn right when it should be left or vice versa. This was a problem on the 2016-2017 models also.
- Kennewick, WA, USA
Can not see anything backing up in the dark because of backup camera. The picture on the screen is grainy and washed out so all you see are blobs of nothing.
- Millston, WI, USA
Brand new truck. Stuck at the gym in the middle of the night truck wont start. The interior lights, head lights, and radio wont shut off. Vehicle wont start. I'm assuming the battery was drained because interior lights, exterior lights, radio, wont shut off. Has to be some kind of electrical malfunction. Waiting on GM roadside.

The backup camera is entirely too bright at night. It is nearly impossible to see the mirrors due to the brightness
