Chevrolet Silverado 1500 knocking problems

Filed Oct 28, 2026 · Engine · TN

I bought this vehicle 9/2023. On 02/23/2024, I started my truck, and heard a very loud knocking noise upon starting it. I turned it off. Called the dealership to come pick it up. They were able to repair it, by repairing some of the lifters on one side. Fast forward to 10/25/2026, I started my truck and heard the same knocking noise. Called the dealership to come pick it up. They say my truck is no longer covered under the power train warranty, and it will cost $10,000 to replace the other side of lifters and cam shaft.

My truck started making a ticking noise. When I took it in for an oil change, the mechanic said it was a common problem with Silverado 2.7 engines

My 6.2L is experiencing engine knocking. Sounds like ball bearings rolling around at idle and acceleration. Its been seen by GM dealer and they notice "something" isnt right but say its not part of recall at this time. They want it to fail more before pursuing.

I have a 2022 Chevrolet Z71 with a 6.2 l L87 engine. The motor blew up for what the recall is for from chevrolet.The crank and all that stuff seized up while my step son was driving it was told to burn Chevalier of rock. Hill, where they said, yep, this is the exact recall problem that we've been having with all these trucks. And the truck still isn't running, right?It's still knocking and making weird sounds and losing power after getting a new motor

I am reporting an engine failure on my 2022 Chevrolet Silverado equipped with the 6.2L V8 engine, following completion of the federal safety agency Safety Recall 25V‑274 (GM N252494000). The recall was performed when my vehicle already had over 150,000 miles. At that time, GM performed the oil-and-cap remedy rather than replacing the engine. Approximately 9,000 miles after the recall repair, at approximately 193,000 miles, the engine began making knocking noises and subsequently required replacement. There was no low-oil warning that we observed before the failure ( both in the vehicle nor on the app) and we were not aware of any oil leaks. The vehicle had also been serviced by our local mechanic approximately 3,000 miles before the failure, at which time the mechanic advised that an oil change was not necessary. I am concerned that this failure may be related to the connecting-rod or crankshaft defects identified in the original GM recall and that the recall remedy may not have adequately corrected the problem. I am requesting that the federal safety agency review this complaint as a possible engine failure following completion of Recall 25V‑274 and consider it in its investigation of post-recall engine failures. This vehicle is currently at a dealership waiting for an engine replacement. In speaking with the service manager at this dealership, he agreed that this was related to the recall and actually said to me that he felt that by replacing the oil with the heavier oil (as recommended by the recall), is probably the what caused the engine failure.

On my way home to [XXX] from [XXX] around XXX, my 2021 Chevy Silverado with 84,xxx miles with the 6.2 L engine started to make a popping sound. I checked my dash for any error codes and there were none. The oil pressure, temp, and transmission temp gauges all read normal. I stopped and topped the gas tank off with premium gas and checked the oil level, which was good. I was able to limp the truck back to my house. The next morning when I started it, there were error codes and the engine was still making the popping noise as well as a louder knocking noise. I started researching the symptoms, called two local independent shops and concluded the DFM system that shuts cylinders off to conserve gas has failed and caused the lifters to fail. I was told the failed lifter could and probably did damage the cam shaft(s). If I kept driving it, the camshaft damage could cause complete engine failure and more safety consequences. One shop quoted $5000 to replace lifters and $8000 if the camshafts were damaged. The other shop was similar, but offered a rebuilt engine for $12,000 because the lifters, camshafts, and new GM crate engine were all back ordered with no ETA from the local Chevy dealership. After weighing my options, and needing a truck, I decided to trade in my damaged truck. I contacted the GM concierge on XXX and was told to call back when the dealership had my damaged truck and could diagnose it. On XXX I called them back and they said they wouldn’t help because I traded it in. I had no plans to trade it before the engine failed and took a substantial hit on the trade in price that GM should have helped with to cover their faulty DFM system that caused the lifters to fail, which the dealership confirmed was the problem. They said they wouldn’t know if the camshafts were damaged until they took it apart, which they decided to not do and send it to auction instead.

The 2026 Chevy 1500 Silverado 6.2L engine had a slight knocking sound from the date I purchased it brand new in march 2026. I was driving home on a evening in July 2026 and the truck began to squeak, knock very loudly and shake violently. The truck then locked up and completely shut off while I was driving 45 mph down the highway. The vehicle had approximately 3,000 miles on it when the incident occurred. The truck’s violent shaking and sudden loss of power while traveling 45 mph created an immediate risk in which I did not have control of the vehicle and could have caused me to be unable to safely maneuver out of traffic. Thank God there was light traffic at the time and also a wide empty parking lot straight ahead of me when the truck shut down. The incident also placed other drivers in danger of colliding with my disabled vehicle or taking sudden evasive action that could cause an accident. I had it towed directly to the dealership service department and according to their report, "found catastrophic internal engine failure."
