I had to get that replaced because I needed my truck. The dealership had had it for almost three weeks at that point. $1300 to replace a lifter.

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,

- Desoto, TX, USA

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.
