SERVICE BRAKES, ENGINE, POWER TRAIN
Vehicle lost engine power on the road. Light display came on stating engine reduce power. It would not pull the trailer. Had to pull over and the display went away only to appear again later. We brought vehicle to chevrolet dealer . The part needed to hopefully fix is on backorder. There is also recall with no available remedy. This is a revenue generating vehicle. We had this problem happen on and off. Dealer didn't want us to bring in until the light physically stayed on dashboard for them to assess vehicle. It was now been in shop for over 2 months

My 2020 Chevrolet Silverado 1500 LT with the 3.0L Duramax diesel engine has experienced three separate failures of the coolant control valve over a span of less than two years. Each failure resulted in the vehicle entering reduced engine power mode, which drastically limits acceleration and the ability to maintain safe driving speeds — particularly dangerous on highways or in heavy traffic. Chronology of Failures: October 2023: First coolant control valve failure. Part was backordered. Repair took ~6 weeks. June 2024: Second failure of the same part. Another 6-week delay in repair due to part availability. June 2025: Third failure of the same part. Vehicle is currently inoperable and unsafe to drive. Each time, the failure triggered a check engine light and immediately placed the truck into reduced power mode. This issue significantly compromises driver safety, especially in high-speed or congested environments, where limited acceleration can increase the risk of collisions. Safety Concerns: Loss of acceleration power at critical times (merging, overtaking, etc.) Unpredictable vehicle behavior Extended unavailability of parts leads to prolonged periods without a functional vehicle Possible underlying design flaw or recurring part defect Given the recurrence, safety risks, and the number of similar complaints I have seen from other owners, I believe this is a widespread and systemic defect that deserves NHTSA investigation. Requested Action: I urge the NHTSA to investigate the frequency and root cause of coolant control valve failures on the 3.0L Duramax engine in the 2020–2022 Silverado models. This is not an isolated incident, and repeated failures of a critical engine cooling component warrant a safety recall or technical service bulletin (TSB) requiring redesign or replacement with a permanent fix.

POWER TRAIN
The contact owns a 2020 Chevrolet Silverado 3500. The contact stated while driving 65 MPH, the rear wheels locked-up. The contact was able to pull over to the side of the road. The contact resumed driving, but the vehicle was driving roughly, and the failure recurred while driving 30 MPH. The check engine warning light, the electronic stability control warning light, and other unknown warning lights were illuminated intermittently. The contact pulled into a gas station, where a mechanic inspected the vehicle, but the cause of the failure could not be determined. The vehicle was towed to the dealer, where it was diagnosed with transmission failure. The contact was informed that the transmission needed to be replaced. The vehicle was not repaired due to the cost. The contact related the failure to NHTSA Campaign Number: 24V797000 (Power Train); however, the VIN was not included in the recall. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was unknown.

Transmission is sputtering when trying to shift. Mostly at low speeds it's extremely jerky like it doesn't want to go. Had Transmission fluid and filter changed, but it did not help.

I was driving and came to a stop at a red light. When accelerating on green the transmission would not go into gear, stalling my vehicle. Nearly causing the vehicle behind me to rear end me. The vehicle eventually went into gear and started to slowly accelerate with shuttering of the transmission.

ENGINE
2020 Chevy Silverado LTZ 6.2 V8 10 Speed. Started having issues with hesitation/shudder. Dropped off at a Chevrolet dealership for a diagnostic. The dealership pointed to a potential transmission issue. After having the truck for several days, they reported nothing wrong. Said they drove the truck, checked the transmission fluid, and couldn't find any issues. Picked up the truck and took it to a local repair shop. That shop drove it, but could not re-create the issue I was describing. I opted to have the transmission fluid flushed in hopes of fixing the shudder/hesitation I was feeling. After picking up the truck and driving it a couple hundred miles, the issue was still present. I made another appointment at the same local shop. This time, they called me saying the issue I'm feeling is the same problem that's been happening to these engines, the dreaded AFM (Active Fuel Management) system is starting to fail. I was told by the shop it's only a matter of time before the entire engine fails. The only way to fix the issue is to delete the AFM system by removing the old parts within the engine and replacing with new parts that do not use the AFM system. This would cost approximately $6,000 to complete.

ENGINE
Was driving on the interstate on [XXX]. While driving, the truck suddenly slowed down and lost power. The check engine light came on and then after about a minute a message popped up on the dash saying that the truck was in reduced-power mode to prevent engine damage, or something like that. It slowed to roughly 50mph and I had to drive for maybe 5 miles to reach the next exit, narrowly avoiding collision from behind with cars driving upwards of 75. Pulled off the road to the first parking lot, then got towed to the nearest Chevy dealership in Shawnee, Oklahoma. The diagnosis was a blown connecting rod that had occurred while driving on the interstate, resulting in a necessary total engine replacement. The truck was repaired in Shawnee, Oklahoma at the dealership. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While driving my truck the engine completely shut down. All the dash lights came on initially but then only the check engine light stayed on. My truck never would start back up after that. It was towed to GM dealership who diagnosed catastrophic engine failure.

TIRES:TREAD/BELT, TIRES
Goodyear Wrangler Trail Runner AT LT275/65R20 126/123S I had been traveling at 55 mph when I started noticing a vibration in the steering wheel and front wheels. It started getting a little more noticeable, so I pulled over and checked out the front tires. I checked the lug nuts, looking for missing wheel balance weights, and checked the tires for any bulges. Everything seemed to be ok. Started driving again and the vibration was still there. As I was slowing down for a traffic light, the tire tread separated, and I pulled over. The tire remained inflated so I didn't hurt the rim. I changed the tire and after I get home the tire blew out.

When accelerating the transmission shakes violently under the hood. It shakes so bad that other vehicles can hear it the vibration is intense until you take your foot off the gas and then try to accelerate again it happens a few times then it’ll stop until the next red light. Slowly accelerating makes it worse but doesn’t matter either way.

Was driving on highway and vehicle went into "engine power reduced" and dropped from 60mph down to 35mph and then steadily decelerated down and wouldn't go over 18mph. Per mechanic it is the engine coolant control valve and the part is not available and could be months to a year before the part is available. Online shows this is a widespread issue with GM / Chev vehicles but no recall has been ordered and parts not available anywhere. Completely unacceptable to pay $65000 for a vehicle that is just barely 5 years old and have this kind of issue and manufacturer doing nothing about it.

ELECTRICAL SYSTEM: INTEGRATED TRAILER BRAKE CONTROL
The contact owns a 2020 Chevrolet Silverado 3500. The contact stated that while hauling a 2020 Heartland Cyclone, the trailer brakes unexpectedly deactivated. The contact stated that the trailer brake was disconnected, and the warning light to check the trailer winch was illuminated. The vehicle was taken to the dealer, who was unable to determine the cause of failure. The vehicle was not repaired, and the failure persisted. The vehicle was returned to the dealer and the contact was informed that the trailer brake module had failed and needed to be replaced. The trailer brake module was replaced. The failure and repair were linked to an unstated Technical Service Bulletin; however, the VIN was not included. The TSB stated that the RV battery was interfering with the vehicle battery and causing the failure. The contact stated that the failure persisted. The vehicle was returned to the dealer but was not diagnosed or repaired. The manufacturer was informed of the failure. The manufacturer referred the contact to the NHTSA Hotline to report the failure. The failure mileage was approximately 52,000.

STEERING
Lost power steering! Almost impossible to make any turns. The dash has ESC fault and power steering fault. Says drive careful! How can I drive careful if I can't turn the truck? Only 79k miles! GM must recall their bad design and replace it with a design that is proven not to fail!

ENGINE, POWER TRAIN, VEHICLE SPEED CONTROL
When a Check engine light is on it's for a low voltage on the charge air coolant sensor, took to the chevy dealer, they replaced a connector to the sensor, at a cost of $600 never got off lot, light returned, they then said I need a new engine wiring harness at a cost of $10.000, the dealership said this is a problem with these trucks and GM knows about it but won't recall them. Now I'm struck with a 5-year-old truck that I can't use, When this light is on, I also receive an Emission system warning, and the truck deregulates and goes in limp mode. as speed is reduced it becomes dangerous to drive in traffic, as GM knows about this, they should recall these trucks and fix the problem, they even say it's because cutting corners on the wiring harness cover causes this problem. as a senior living on a fixed income there's no way my wife or I can get this repaired, so were forced to drive it in limp mode until it dies on us, hopefully not in heavy traffic.

ELECTRICAL SYSTEM, SERVICE BRAKES, VEHICLE SPEED CONTROL
Vehicle started and behaved as expected when leaving my home and for a dozen lights or so between my home and place of the incident. While stopped at a red light, the auto stop function shut the truck down as normal. On re-start when getting green light, after releasing brake pressure, the start up was belabored for two turnovers before starting up. As I pulled off the stop with a green light, the dash lights illuminated and display started rolling through system failures, one of which was the brakes system and ESC. I cautiously proceeded through my turn to a thankfully quiet intersection as the brakes were completely unresponsive. I had ZERO brake function. I was able to slowly come to a rolling stop enough to get the truck in park where I turned it off and back on and the brake function returned. I cautiously drove to the local chevy dealer where I was informed that the battery drain pulls from low voltage when it needs extra power for start up. This is utterly terrifying that it is even possible for the battery to start the truck WITHOUT ANY BRAKE FUNCTION. Had this happened just two lights before or after where I was, it would have been a news headline. I could have easily been headed up and over a bridge leading to a catastrophic event at the bottom where I would have been completely unable to stop my truck by any means other than a collision. I would have preferred a dead battery at a red light. Seems a whole lot safer. I'm now stressed beyond measure at the thought of some failure in the future that could lead to another event such as this. My truck is now a nightmare wondering what electrical malfunction is going to put me and/or my wife and daughter in a life or death situation, let alone others on the road. This shouldn't even be an option for the truck to start at the expense of a critical safety function. Not to mention there is no function for the auto start stop system to be deactivated permanently by my choice. I am beside myself and scared to drive.

I am writing to formally lodge a complaint regarding my Chevy vehicle, which is experiencing significant engine issues. The motor is knocking, and the check engine light has illuminated with trouble codes P0011 and P0016. These codes indicate problems with the camshaft and crankshaft timing on Bank 1 (driver's side in a V6/V8 engine). Specifically, P0011 signifies that the camshaft timing is over-advanced, while P0016 points to a correlation issue between the camshaft and crankshaft positions. These issues are often related to the Variable Valve Timing (VVT) system and may be caused by faulty camshaft or crankshaft sensors, timing chain problems, or solenoid issues. This situation directly correlates with a recent recall affecting similar VIN numbers for 2021-2024 models with similar engines. An independent service has confirmed that my truck requires a new engine, which aligns with the issues addressed in the aforementioned recall. I urge the NHTSA to investigate this matter further and consider extending the recall to include my vehicle, as the problems I am experiencing are consistent with those covered by the recall.

Oil pump went out. Got it repaired. Then, a few days later, while driving on the freeway at 70MPH the engine made a lot of noise then quit in middle of the freeway leaving me vulnerable to being hit. Was able to coast in neutral to the edge of the road. Has 73000 miles on it. Dealer says I need an engine replacement after just spending $5,500 for oil pump replacement. Has been at the dealer over a month and no replacement engine is available.

The engine seized up. Yeah, the truck is at a trusted mechanic and he told me that the engine seized. No warning signs. The truck wouldn't start and the engine light was on.
