I am reporting a safety concern that I believe should be included in an existing or expanded recall for the Chevrolet Silverado. The issue involves engine replacement due to metal shaving being found in oil & brake failure, which occurred on 05/01/2025 The problem with the brakes occurred while I was in heavy traffic in Dallas, Texas multiple times, resulted in multiple near-accident experiences that day. The truck has been diagnosed by a mechanic, at the Chevy dealership and I believe this defect poses a serious safety risk and may be affecting other Silverado vehicles outside the current recall scope. I have driven the vehicle to Chevy and stayed in constant contact with the dealership, had diagnostics done, but the issue has not been resolved. am requesting that the NHTSA investigate whether this issue warrants inclusion in the current recall or a new safety campaign. I have on had this vehicle less than 2 years and I put less than 70K miles on it. I purchased it from vandergriff Chevrolet in Arlington,

Metal shavings were found in my oil after the check engine light came on a day before I took it in. The day that I took it in my brakes limited the speed of my truck to 43 mph due brake malfunction. The dealership called and told me that they recommend engine replacement due to the metal shavings found in the oil. I can give more in depth info as I receive it but I just wanted to alert Chevy that my vehicle is doing the same thing that the others are getting recalled for.

My engine is out due to the piston rings failing and is at a dealership waiting for a new engine. The engine for this vehicle is on national back order with no ETA in sight. Out of nowhere the low oil light came on and I had to stop immediatley to check it as to make sure nothing happened while I was driving down the road. The dealership that has it has confirmed that the issue was due to the pistons. This vehilce was purchased brand new and has had perfect maintenance performed on it since day one. The dealership has inspected the vehicle. The low oil light first came on in February. I took it straight to a place to have them check it and change the oil again just until I could get it to the dealership a few days later. I was advised to have an oil consumption test done. On the 3rd time, which would have been around 3000 miles, it had already consumed more than a quart of oil. They did a borescope and confirmed that the pistons are bad and because of this the inside of the engine is scored. Now I need a new engine on a vehicle that I've taken perfect care of. I believe that this vehicle should be included in the GM recall with the other 6.2 engines as this is also a 6.2 engine in the same year range. I have included the paperwork from the dealership and my carfax showing maintenance.

Around May 20th, 2022, I was driving the pickup when it suddenly the engine turned off on me. I was travelling at approximately 40 mph on city streets and was able to control the vehicle and park the vehicle and restart it. That same week, I took the vehicle to Chevrolet on the city of Orange, where it was inspected. According to the mechanic, no issues were located. Nothing else was done to the vehicle and as a result, I fear the same issue will happen again in the future.

On March 16, 2025 driving to church in Siloam Springs Arkansas it lost power while going down the road at 45 mph and we started hearing an oddly loud noise and then the check engine light came on. We limped it into the church parking lot. We came out from church and started the engine, there was no check engine light. We pulled out of the church parking lot and started down the road and we got up to 55mph when the oddly loud noise occurred again and check engine light came on. We pulled over and called for a tow to the dealership Superior Chevrolet of Siloam Springs. They found the engine was missing on cylinder #2 and the #2 connecting rod was bent. They found the lifter on #2 exhaust was broken. They inspected the cam and all the lobes looked good. They replaced the right bank of lifters and guides with all gaskets seals and pipes. Changed the oil and filter. Refilled the coolant. Test drove 10 miles and verified operation. It had 58,055 miles when this failure occurred. Our safety was at risk as a result of an immediate loss of power while traveling speeds over 40mph.

The Engine has unexpectedly spun a rod bearing causing the engine to run erratic, low power and knocking. I have taken it to a automotive repair shop and that is their diagnosis. This is the 6.2 liter that has the issue that has recently had a recall issued but my VIN does not show a recall

The engine light is blinking while driving on the highway, it comes and goes, I have a video for that. Also it has a ticking noise and I-??ve had the noise since I bought the truck and took it multiple times to the dealership, first it was the pump they replaced for free but the ticking never went away, I took it back and they said that all the trucks tick like that, and all that should be documented. Also while sitting still it sounds like the truck is shacking just a little. I have an appointment to which I have to pay $250 for them just to look at it. I think that my truck should be up under the new recall for the 2021 Chevy Silverado because my truck is knocking and also throwing off a blinking engine light.

While driving at 35 mph my check engine light, Service Parking Break light, ABS Maintenance light all came on and my truck lost power to a point I could not go over 10 MPH. It started chugging and running very rough. Fortunately I was close to home and got it in the driveway. I called the dealership to set and appointment, tried to drive it down my driveway and couldnt get it over 10 MPH. I called a tow company to take it to the local dealer I purchased from. After a couple days the dealership called and said there is a lifter problem but wasnt fully into the engine to see if there was more damage and would call me once more testing had been done. I have photos of the tow company tow bill ($169) and a photo of them lowering the bed to put the truck on it to haul to dealer if needed.
