ENGINE
At approximately 3,000 miles, the engine began making a loud knocking noise that became progressively worse while driving. The truck was diagnosed as needing a complete engine replacement. No warning lights, no check engine light, nothing. For someone inexperienced with vehicles, you could easily be in big trouble on the highway and a potentially life threatening situation. My primary concern is that there was no warning that such a major engine failure was about to occur. An engine that fails with so few miles raises concerns about the possibility of sudden loss of power, loss of acceleration, or engine seizure while driving in traffic, on highways, or while towing. A failure under those conditions could significantly increase the risk of a crash. The vehicle has been out of service while I continue making loan and insurance payments on a brand-new truck that I cannot use. The replacement engine is on national backorder, leaving me without a clear repair timeline. After researching this issue, I found numerous reports from other owners describing similar failures involving the 6.2L V8 engine. Based on the volume of owner complaints, there appears to have been a significant increase in reported engine failures involving 2026 model-year vehicles. This suggests the problem may not be an isolated incident but instead could indicate a broader defect that deserves investigation. As a result of this experience, I no longer feel confident or safe driving this vehicle, even if the engine is replaced. I purchased a brand-new truck expecting long-term reliability and peace of mind, but instead I experienced catastrophic engine failure at only 3,000 miles. I respectfully request that NHTSA investigate these engine failures to determine whether a safety-related defect exists and whether further action is necessary to protect consumers. I have requested a buyback, but GM completely denies it. Such a horrible Expy with manufacture.

POWER TRAIN, VEHICLE SPEED CONTROL, FUEL/PROPULSION SYSTEM
What component failed: The “regen on demand” switch broke while using it. Safety: This incident put me, the occupants of my vehicle (my children), and the vehicles around me at risk. Reproduction: There was no need. It is exceptional obvious that the switch is broken and has failed. Inspection: The truck and broken switch were observed by the dealership that services the truck. Warnings: There were no precursors to the failure. Narrative: On Thursday, 7/16/26, I was driving my 2026 Chevrolet Silverado EV. I normally drive in “single pedal drive” mode which provides energy recovery in lieu of mechanical braking. Additionally, I use the “on demand regeneration” for additional slowing and energy recovery. On demand regeneration is somewhere between single pedal drive and mechanical brakes. During this drive I was coming up to stopped traffic and slowing using the regen on demand switch. The switch snapped / broke and the additional slowing / energy recovery stopped instantly. I had to immediately apply the brakes in order to remain a safe distance from the vehicles in front of me. While I am able to safely operate the vehicle without this function, the manner in which the failure occurred is concerning and should be investigated. I am happy to speak with anyone who needs more information.

ENGINE
On June 22, 2026, my Chevy Silverado was inoperable and had to be towed to the Chevy dealership. After a period of examination by the service staff, it was deemed to have experienced CATASTROPHIC ENGINE FAILURE. My truck has the 6.2L engine, but was NOT included in the original recall. It had just been serviced on 6/19/2026 and was only driven approx. 20 miles to my home. I have a video of what it was doing when I went to leave for work two days later on 6/22 when it wouldn't run without major issues and a burning smell.

STEERING
I had a complete loss of steering and had to have the truck towed to the dealership. This could have caused a very serious accident. There was no previous warning - it just went out. The dealership charged me $2183 to replace the steering gear. According to the literature, the steering function should last to well past 100K miles (my truck had 66,552 miles on it). In addition, there are multiple reports of steering going out online - perhaps a recall is in order. The literature also states that if diagnostic code C1599 then the steering rack is completely fine mechanically but it has simply lost its electrical connection. That is the code that the dealership saw - it sounds like the fix could have been much simpler and cheaper.

FUEL/PROPULSION SYSTEM
I own a 2015 Chevrolet Silverado 3500HD Duramax diesel. At approximately 130,000 miles, the high-pressure CP4 fuel pump failed internally, sending metal shavings throughout the fuel system and contaminating major components. The truck suddenly lost power on the freeway and became inoperable without warning. I was barely able to get out of traffic before it had to be towed to a Chevrolet dealership. This created a serious safety hazard, especially considering the risk if it had happened while towing my fifth wheel with my family. A failure like this should not happen at this mileage on a heavy-duty diesel truck. I also cannot afford the extremely high cost of repairing the entire fuel system. From my research, many other owners have experienced the same CP4 fuel pump failure, which often destroys the entire fuel system and leads to very expensive repairs. I believe this is a widespread defect, not normal wear and tear. I ask NHTSA to review these failures and take action to protect vehicle owners from similar dangerous and costly failures. This truck currently sits at the dealership as I cannot afford the repairs and GM will not fix what they know is faulty parts.

STEERING
Without prior warning my power steering went out. This could have been life threatening. I had to have it towed to the dealership (Voss Chevy, Centerville OH). The truck had 66,552 miles on it and the extended warranty that we purchased thru Voss expired on 26 Mar 2026 and although we were under the 75K mileage, they would not honor it (planned obsolescence?) So they replaced the steering gear for $2183. After researching, the literature says that diagnostic code C1599 (which is what Voss saw) indicated that the steering rack is completely fine mechanically but it has simply lost its electrical connection. In addition, literature says that a steering rack should last at least to 100K miles. There are also multiple issues documented on carcomplaints.com regarding the loss of power steering. Perhaps a recall is needed. In addition, I believe we were mislead as to what repairs were needed.

ENGINE
A.The engine is stalling while driving. This has happened four different times. Three times while towing, and one time while backing up a small hill. This is a scary situation because three of the four times almost caused an accident. 1.We were driving to Texas, pulling a pontoon boat. While exiting the highway, we were entering into an intersection at a speed of about 10 miles per hour, and the truck shut down. The truck said, “Start the motor and place it into gear.” Or something similar to that. 2.We were in stop-and-go traffic on the highway, and the truck shut down. Once again, I had to restart the motor and shift into gear. 3.We were entering a parking lot from the main road, and the truck shut down. Again, I had to restart the motor and shift into gear. 4.The three times above are during a time when we were towing. The fourth time is when we were backing up a small hill. The rear tires lost traction and spun for a second or two, and then the truck shut down and started to roll forward. Once again, I had to restart the motor and place it into gear.

EXTERIOR LIGHTING, FORWARD COLLISION AVOIDANCE: WARNINGS
The left front turn signal becomes inoperable at times. The foreword collision indicator warning will come on unprovoked at times. Both conditions correct when you cycle the ignition switch. I consider the turn signal problem a safety issue because it happens with no warning and oncoming traffic may not know I am turning left or changing lanes. When the foreword indicator appears, I doubt the system is operable.

ELECTRICAL SYSTEM, ENGINE, POWER TRAIN
I have been having issues with my vehicle for the last 1,000 miles or so where it appears to be losing power while accelerating normally, i'm not sure if the issue lies with the engine or powertrain/transmission. I took to dealer last week and they were unable to reproduce. The issues have been getting more frequent and intially were only occuring after the vehicle warmed up, now it has started while vehicle is cold. Feels like the power drops (rpms drop) during a normal acceleration. As of 7/16 I now have a check engine light on, onstar indicates an issue with my engine, transmission, electrical. This is putting myself at safety risk along with others as during my normal drive the engine is losing power and could either leave me stranded or cause an accident.

Vehicle transmission repaired at 77,000 along with a new torque converter. Torque converter and transmission both failed again at 115,000 miles. GMC currently replacing the 3rd torque converter with 130,000 miles. I have spent over $14,000 on 2 transmissions and 3 torque converters on a vehicle I've owned for 6 years.

On June 27th 2026 at approximately 3am, I was driving my Chevy Silverado Trail Boss with 6.2 engine, it suffered a sudden catastrophic failure and it completely seized while in motion. There were no warning or signs given while vehicle was in motion. This resulted in an immediate highly dangerous loss of propulsion on a dark 2 lane road. The vehicle would not crank and had to be towed to Estero Bay Chevrolet.

ENGINE AND ENGINE COOLING
The contact owns a 2021 Chevrolet Silverado 1500. The contact stated that the engine occasionally overheated. The check engine warning light was illuminated for a day, and there were six diagnostic trouble codes displayed. The vehicle was taken to the dealer to be diagnosed, and it was determined that the coolant flow control valve was inoperable and needed to be replaced. The vehicle was not repaired. The manufacturer was informed of the failure and confirmed that the repair was not covered under warranty or recall. The contact became aware of GMC Special Programs: N252508340 and N25250834, which were associated with the failure; however, the VIN was not included. The manufacturer referred the contact to the NHTSA Hotline to report the failure. The failure mileage was approximately 105,000.

FUEL/PROPULSION SYSTEM
Truck was operating on the highway at highway speed. Suddenly the truck went into a drastic engine power reduction mode and severe automatic downshifting occurred; the truck came to a complete stop on the highway. Diagnostics proved to be a CP4 injector pump failure sending metal into the fuel system, needing a complete contamination kit and new CP3 pump conversion. This apparently is a known defect in GM vehicles and should have been recalled.

The contact owns a 2024 Chevrolet Silverado 1500. The contact stated while the vehicle was parked, the contact attempted to shift the into reverse and the gear shifter failed to respond as needed. An independent mechanic was contacted. The vehicle was taken to the independent mechanic and was diagnosed and determined that the vacuum modulator needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 17,000.

FORWARD COLLISION AVOIDANCE: WARNINGS
The forward collision warning is excessively sensitive to vehicles and pedestrians. I've had the alert go off recently for something so simple as pulling into a parking spot. It goes off frequently just driving past pedestrians and throughout what I consider to be normal driving where I am not coming close to a collision with a vehicle. It is very unsettling and startling when the alert goes off indicating that I am coming close to a collision with a vehicle or a pedestrian. I had a 2023 Silverado 1500 LT/2.7 Turbomax engine and it was not this sensitive. I fear that this may actually cause an accident at some point or if the emergency braking were to activate with another vehicle behind me.

UNKNOWN OR OTHER
Key will not fully turn back and release, keeping the accessories running. After many start, shift, move a little and waiting for a period of time it eventually turns to normal to remove. I’ve seen articles on if it says “shift to park” on the dash lights and it does not. Bought used with 70,000 10/24 and continues to get worse.

ENGINE
On Sunday, July 12, 2026, the 6.2L V8 (L87) engine in my 2023 Chevrolet Silverado 1500 ZR2 seized and locked up completely, resulting in total loss of propulsion. I was driving at 65 MPH when it felt like the transmission was slipping and I lost power and coasted the truck to the side of the road. COMPONENT: Engine (6.2L V8, RPO L87) — connecting rod/crankshaft failure consistent with Safety Recall N252494001 (NHTSA Recall 25V-274). The vehicle is available for inspection. It is currently at Cable Dahmer Chevrolet, where it was towed on July 13, 2026, and remains inoperable. SAFETY RISK: The engine seized during operation, causing sudden and complete loss of propulsion in traffic. This is the exact failure mode identified in Recall 25V-274 as increasing the risk of a crash. CRITICAL DETAIL: This vehicle previously underwent inspection under Safety Recall N252494001 and PASSED on Feb 3rd 2026 at VAN Chevrolet in Kansas City. GM deemed the engine non-defective and issued extended warranty coverage of 10 years/150,000 miles under the associated special coverage program. Despite passing GM's recall inspection, the engine suffered catastrophic failure. This appears directly relevant to NHTSA's open recall query regarding the effectiveness of GM's recall remedy. DEALER CONFIRMATION: A technician at Cable Dahmer Chevrolet has verbally confirmed the engine is locked up/seized. Formal diagnosis is pending master technician sign-off and submission to GM, expected the week of July 20, 2026. The manufacturer has not yet inspected the vehicle. WARNING SIGNS: No warning lamps, messages, or symptoms appeared prior to the failure. The engine failed without warning
