Most mornings after starting truck and driving off, it appears to be a hesitation or brief loss of power. Issue has been present for several years. It's hard to determine if it's engine or transmission issue. Truck is available for inspection. It usually occurs when leaving house in the morning so there is no safety issue because it happens within the first minute of driving. No warnings, cannot recreate issue.

As I’m driving, the vehicle began shaking and ticking sounds could be heard inside the cabin. A check engine light lit up on the dashboard. The idle was rough and it sounded like metal thrashing in the engine so I turned on my hazards and shut the vehicle off in the middle lane of the street. It didn’t want to turn over a couple times but when I was finally able to get it to start again it made the loud ticking and thrashing sounds. To prevent more damage I put it into neutral and had to push it with the help of bystanders to the closet parking lot putting us and other drivers at risk. I had the vehicle towed to the local chevy dealer for a diagnostic and they claim a catastrophic engine failure and recommend complete engine replacement. There were no symptoms of this prior.

When driving in traffic about 10 mph engine shuts down and power steering goes out. . When I slow to turn, the engine shuts down sometimes and the power steering goes out. No warnings. I’m afraid to drive it. I almost hit a lady while turning in a parking lot because the steering went out and it died. Sometime it’s hard to turn the key to start the truck. This has happened 9 or 10 times now.

1. The vehicle's transmission does not operate consistently and safely. 2. At times, the transmission will not engage, and this has placed my family in very dangerous situations when changing lanes. 3. At red lights, at times, the transmission will not engage to drive. 4. When slowing in traffic at times , the transmission will not adjust to the slower speed, although the operator is applying the brakes. Then, without warning, the transmission will engage the higher speed, almost launching the vehicle forward suddenly, potentially into another vehicle or person, depending on the situation.

The vehicle and engine remain in their post-failure condition and are available for inspection upon request. The problem was confirmed through diagnostic testing, which retrieved code p0305 (cylinder 5 misfire). The misfire is present whenever the vehicle is running and is reproducible. The vehicle has been inspected by a service center and diagnosed with a cylinder #5 misfire. The vehicle has not yet been inspected by the manufacturer or insurance representatives but is available for inspection upon request. No police inspection was required as there was no collision. The failure occurred suddenly while driving at approximately 45 mph. Immediately after the failure, the check engine light illuminated and the engine began running extremely rough. When during warranty, the vehicle was serviced multiple times for engine shuttering and skipping.

The contact owns a 2019 Chevrolet Silverado 1500. The contact stated while driving 65 mph, the vehicle experienced reduced power and failed to exceed 25-30 mph.

The vehicle was taken to the dealer, where it was diagnosed and determined that cylinder #5 wall was damaged and there was oil found on the #5 piston. The dealer determined that the engine had experienced an internal mechanical failure and needed to be replaced. The vehicle was not yet repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 83,260.

Vehicle has experienced repeated internal engine failures related to the exhaust valve lash adjusters and valvetrain. The engine developed abnormal valvetrain noise, misfires under load, and loss of power. The check engine light would only flash during hard acceleration or when passing another vehicle (wide-open throttle), then turn off after approximately 10–15 seconds and never remain illuminated. Because the warning light would not stay on, the vehicle continued to be operated without clear indication of an active or worsening engine failure. Dealer inspection confirmed exhaust valve lash adjuster failure, which led to camshaft and valvetrain damage. This failure has occurred more than once, including after prior dealer repairs. This is a serious safety concern because the vehicle was driven at highway speeds and during passing maneuvers while experiencing internal engine damage and misfires, without persistent warning to the driver. Sudden power loss, stalling, or catastrophic engine failure during acceleration or passing presents a risk of crash or injury. This appears to be a systemic engine defect rather than normal wear, as the failure recurred and was not reliably detected by the vehicle’s monitoring system.

My truck has the 6. 2l engine that is in recall. I received my letter and took it in for inspection and oil change as recommended (Dec 15, 2025). Less than a month later (Jan 26, 2026) my engine started making loud noises. Got it to the dealership. The claim found metal in oil, spun rod bearings. They did replace engine under recall at no charge but then a week later my check engine light came on. Bad battery control module. Not sure if this was due to engine swap, etc.

My vehicle was part of the recall n25494000 l87 engine loss of propulsion. Vehicle went in for recall on Sep-30th 2025, picoscope inspection was done and vehicle passed. Oil was changed to 0w 40 with new oil filter. Dec-26/27 of 2025 vehicle started stalling, for no reason but no engine light. The dealer said there was no problem because there was no engine light, so there was no way to find out what was wrong. January 11th 2026 vehicle lost propulsion 7 times on the freeway, vehicle had a hard time re-starting and started smelling oil burning smell. Vehicle engine light stayed on, 1/11/2026 vehicle was running a little rough with abnormal tapping noise but made it to the dealer for inspection.

While driving the vehicle I began to hear a ticking noise in the engine (lifter tick) and the check engine light came on. The vehicle began to lose power and started shaking. I stopped the vehicle and turned it off and restarted it and began to drive as I was not far from home. I found that the vehicle did not have full power and was not firing on all cylinders. After getting the vehicle home a diagnostic code showed cylinder 2 was not firing. The vehicle was towed to the dealership who confirmed there was a bad lifter and roller that dug into the camshaft. The sudden loss of power and shaking of the vehicle while driving is the safety concern. It seems that this is a common problem with these engines that gm is aware of and has failed to address.

I have experienced a catastrophic engine failure due to the faulty gm dfm lifters and oil pump. I was advised that my vehicle will need a new engine. I know there is bulletin no. : 24-na-173 for my vehicle. I have contacted gm, and they advised that there is nothing they can do since the truck is out of warranty. I know they are under investigation for the 6. 2 l engine failure issues, and I feel as if this needs to include the 5. 3l engines as well. This is very disappointing since I purchased this vehicle new, and have meticulously maintained it. Perhaps the cpa needs to get involved as well.

I am reporting a manufacturing defect involving general motors’ active fuel management (afm) system that caused catastrophic engine failure in my 2016 Chevrolet silverado (VIN: [xxx] ). At approximately 78,000 miles, my vehicle experienced piston and lifter failure requiring full engine replacement. This failure occurred without warning and aligns with thousands of consumer complaints regarding afm-related oil consumption, lifter collapse, and engine damage in gm vehicles. This is a known design defect that gm has addressed through technical service bulletins and engine redesigns, yet many consumers continue to experience premature failures at low mileage. This defect presents a safety and reliability concern, including loss of power while driving and significant financial burden to vehicle owners. I respectfully request that NHTSA investigate this ongoing defect. Sincerely, [xxx] [xxx] [xxx] [xxx] VIN: [xxx] 2016 Chevrolet silverado information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
