UNKNOWN OR OTHER
Power sliding window leaking water. Available for inspection upon request. Leaking water can lead to mold posing in the vehicle leading to a health concern. Problem was inspected and verified by dealer and initial service bulletin repair was made to apply vehicle sealant to the top of the window. Window still leaked after the initial repair. Dealer planning to replace the entire rear window. This appears to be an issue with multiple years of GMC and Chevrolet trucks with sliding rear windows. No warning lamps associated.

POWER TRAIN
2024 Gmc sierra Denali ultimate 3500hd equipped with duramax lp5 and Allison 10 speed transmission mission. Towing cargo trailer Thursday November 21 up 4 degree incline transmission let loose banged and popped slammed to a stop almost causing accident and went to limp mode. Took to dealership in show low Arizona. Was told this is common problem and it’s the valve body assembly and parts are 60-90 days out. Mind you this truck was ordered from factory and received in march of 2024. The truck has 21k miles. So now a vehicle I bought specifically for business to haul a spray trailer will be down 2-3 months with no loaner to use to operate our business.

SERVICE BRAKES
Trailer brake controller will intermittently stop working. “Check trailer wiring” will show up randomly on the display and no trailer braking will be available. This has happened with 3 different trailers. The trailer wiring was gone over and the issue is with the truck. Trailer brakes work with other trucks and aftermarket trailer brake controllers. GMC and dealer were notified and no fix is available. Researching online there are several complaints about this. The trailer brake signal should default to being sent similar to all aftermarket trailer brake controllers. This would be much safer rather than not sending the brake signal at all. This HD truck is rated to tow trailers over 20,000lbs and without trailer brakes it causes an extremely dangerous situation. I was forced to pull over on the highway and purchase an aftermarket trailer brake controller to continue safe travel.

POWER TRAIN
Experienced loss of power and inability to maintain highway speeds. The Transmission shifted violently and RPMs went as high as 3500. Was able to move off the highway but cars behind us had to dodge us when it failed. There was warning message on the dash and a CEL. The truck threw two codes P0700, P0747. I was able to limp to a dealer 5 miles away. This is a known TSB with GM. There is a solenoid failure in the Transmission. There is 30-90 day backorder on parts as the failure is so prevalent.

POWER TRAIN
Called multiple dealerships and found out there is a known problem with the valve body for the transmission in these vehicles, which mine is currently being towed today to the dealer. This is what happened to me today, I was driving with my two children on the interstate and all of a sudden I had no drive nothing so the speed reduced quickly. Well behind me there was a 18 wheeler on my back and almost ran into me because I had no more drive on my pickup. Then when it was safe to pull to the side of the road found out there is no reverse either. Making it even more unsafe to drive these vehicles. If I need my reverse to back my vehicle out of on coming traffic’s I would not be able to do so. But this is the big kicker, this valve body for these vehicles are not being produced by gm. The multiple dealer ships that I called have said all the same thing, this is an extreme safety issue that should be recalled.

ENGINE
Exactly what was described in the N192220080 Recall on New Model 2019 Chevy Silverados in cold climates (Like Utah winters) so at 45,280 miles the oil line popped out just like the recall described There were no oil leaks or signs of oil loss in the driveway where the truck is parked. My [XXX] wife (The owner of this vehicle) was only 6 miles from our house on the way to a doctors appt when the “Oil Pressure Low Turn Vehicle Off” light came on. Luckily she wasn't on the freeway so was able to pull into a neighborhood where all of the oil shot out of the engine due to the oil cooler line detaching. Since the N192220080 excluded other trucks made in the same factory as the once recalled in Alaska & Canada, we received no warning of a potential issue like this existing for this model of Silverado. It is also concerning that a known faulty part in all New Model 2019 Silverado 1500s was only recalled in Alaska & Canada. But if we had purchased this truck and registered the vehicle in Alaska, it would have at that point qualified for the free recall replacement instead of the $1,600 bill we were blindsided with (Plus, if she was on the freeway and couldn't immediately pull over, we would have had a seized engine so the truck would have been nearly totaled) INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Vehicle finally restarted and the rest of the trip was uneventful. Second incident, vehicle had not run for two days, got in and while the starter cranks, the engine will not start or run. Engine/Transmission service and fuel system service messages showing on app and on email from OnStar. Vehicle requires towing to dealer.

STRUCTURE:BODY, ELECTRICAL SYSTEM
On at least 5 occasions, my inner tailgate has released itself and gone down during motion. This has been uncommanded. It appears GM has a recall for this but it does not include my truck. The dealership that looked into it agrees this is likely the same issue and GM should include it in the recall.

ELECTRICAL SYSTEM, VEHICLE SPEED CONTROL, BACK OVER PREVENTION: WARNINGS
On multiple occasions, the vehicle has suffered from a severe computer failure. This results in the driver information center losing all data, the climate system shutting down, loss of all driver assistance features, loss of computer based safety systems, and prevents the vehicle from shutting down or being restarted until the batteries are disconnected. This results in the driver having no information about speed or engine parameters while driving. This error has not been reproducible by the dealer however they were able to assess it while one error occurred while driving by them. Their diagnostics show a complete failure of all 3 data buses and failure of the serial data gateway. Troubleshooting thus far has been unsuccessful. During the failure, all errors possible are lit on the warning lamps and the driver information center displays warnings for all vehicle modules. The attached photo was taken during one of the events after pulling off the freeway. While traveling at freeway speeds, the information on the screen was the same indicating no speed. This presents numerous safety risks.

EXTERIOR LIGHTING, UNKNOWN OR OTHER
The reverse lights and high-definition camera system are woefully insufficient for backing up this truck safely in the dark. I have experience several near-misses due to the poor nighttime performance of the video system and reverse lights. This has been ongoing since the vehicle was purchased new. It impacts both the video displayed in the main touchscreen and the video rear view mirror. Furthermore, the reverse lights are sealed LED units that are non-serviceable.
