The transmission has been slipping and shuttering which shouldn’t be an issue at 119,000 miles. This opposed a huge safety risk for me and my girlfriend on the highway. I was driving and it shuttered so bad i had thought the wheel was loose and coming off. I had to pull over on the highway to check the lugs and came to find out it’s the transmission, because it shuttered numerous times after. On top of that the entire trip was the transmission shuddering slightly making the wheels cut the the left and right. But throughout the trip, it had a slight shutter the entire time and a couple of big shutters, and one very large shutter that had my girlfriend think I ran over a bunch of wood in the road resulting in me pulling over being in danger and possibly wrecking from the shaking, and having to exit my truck on the side of the highway with 18 wheelers and other vehicles flying at 80+ miles an hour. Besides the safety issue, there should be no reason for these transmission going out like this at 60k miles and 100k miles it’s extremely cheap of GM and a huge hazard to many families.

VEHICLE SPEED CONTROL, POWER TRAIN, SERVICE BRAKES
Transmission is changing out very hard in each gear. On tonight while I was driving, I lost speed on the interstate and when I push the accelerator, It was like back wheels were locked up. I left it at the next exit gas station and came back and towed it home. Lucky I was able to put hazard lights on and get off the side of the road but it was very slow speed. Yes I have had it look at certified dealer under Cheverolet. It was no warning light. I was going 65 and in a split second the rpm went up high and I was doing like 25. Once I finally made it to the gas station and got out the truck smell like a burning smell

ENGINE, FUEL/PROPULSION SYSTEM, UNKNOWN OR OTHER
I am reporting an issue with a 2020 Chevrolet Silverado 1500 equipped with the 3.0L Duramax diesel engine. The vehicle experienced a failure of the NOx Sensor Position 2, which significantly impacted performance and emissions compliance. GM previously issued Emission Recall N212351211 (March 7, 2023) for other diesel Silverado models regarding improper ECM detection of NOx sensor faults. The issue in my vehicle appears functionally identical, yet this engine and model were not included in that recall. The sensor was replaced and reprogrammed at a Chevrolet dealership at the owner’s expense. After contacting Chevrolet, a customer retention check was provided, covering roughly half of the total cost. While appreciated, the remaining cost burden remains significant. If this model is eventually included in the recall, it may allow for full reimbursement and support for other affected owners. Online forums show that many 3.0L Duramax owners are experiencing similar failures, suggesting this may be a widespread and systemic defect. Due to the strong similarities with the recalled condition in other models, I respectfully request that NHTSA investigate whether this recall should be expanded to cover additional affected vehicles. This issue presents both reliability and emissions compliance concerns. In addition, the vehicle developed a separate mechanical/electrical problem shortly after the NOx sensor failure. Because it involves different systems, I will file a separate complaint regarding that issue.

The oil coolant cooler is leaking oil into my antifreeze reservoir, but nothing is in the oil pan, which could cause damage to the engine a very expensive fix, and this should be covered under drivetrain by all means

ELECTRICAL SYSTEM
The tailgate would open and close on its own. I was about ready to connect my fifth wheel RV for a trip when suddenly as I closed the truck door to back up I saw that the tailgate had opened. I proceeded to put it in park and the tailgate closed on its own. Got out as leaving the door to the pickup I walked to the rear of the truck to notice the tailgate open and close on its own. I am expecting this issue to be recalled for a repair as I have read that 2024 has this same issue and that they will be recalling trucks from 2020-2024.The issue is due to a faulty relay when wet. This vehicle is equipped with power-unlatching tailgate. I believe if this issue would have went unnoticed and continued to hook up my fifth wheel the damage would have been horrific. Thanking you in advance, Sincerely, [XXX] . INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated after an independent mechanic had performed an oil change on the vehicle, the vehicle was moved and parked.

The vehicle was towed to the dealer, where it was diagnosed that the engine needed to be replaced.

The contact related the failure to NHTSA Action Number: PE25001 (Engine, Engine and Engine Cooling). Additionally, the contact stated while idling and while driving at various speeds, the vehicle made an abnormal whining sound.

The vehicle was being used in a normal daily driving routine. I was stopped(fortunately) at a traffic light. The light turned green and I went to proceed and began to press the gas pedal and the engine made a loud pop noise and began to barely stay running. I brought the vehicle to the shop(GM dealership) for diagnosis and repair. The motor had to be rebuilt new camshaft, lifters, etc. The vehicle is also having transmission issues, heavy vibration, hard shifts and constant fluctuations in the rpms while maintaining a set speed. The transmission issue still has not been resolved.

I was driving on Interstate 75 in Ohio when the engine suddenly overheated and completely locked up we were pulling my travel trailer camper at the time which we ended up getting off of an overpass and blocking traffic for several hours until we got the vehicles moved Chevrolet did eventually replace the motor and the entire cooling system with what they claim is a new motor in October of 2024, and within the last couple of days I have noticed a smell coming from the engine compartment that was reminiscent about the smell when it locked up I'm afraid they stuck another motor in my truck that has the same exact issues and once it goes out of warranty I'm going to be stuck with another broke down truck

I recieved a recall notice from Chevrolet stating they needed to install a software update to the truck which will warn if a potential rear wheel lock up is about to occur due to faulty transmission valve body- which was stated that they do not have a fix for. After software update was installed- I was driving about 35 mile per hour on the trip home, and the truck abruptly downshifted very hard, momentarily locking up rear wheels, and the check engine light came on, and the vehicle message came up stating the vehicle was placed in a reduced propulsion mode(limp mode). The next day it did it again on my short drive to work of 2 miles. I took into dealership and they informed me that the valve body had failed- as mentioned in the recall notice. It is now 1 month later and I still do not have my truck back, the part is back ordered, and they have no idea when it will be fixed. I am without my primary form of transportation.
