I was driving with trailer attacked coming from [XXX] , in the middle of the overseas highway (a two lane steet) the truck loss power and stalled and would not start. I was only able to move slightly to the side, with half the trailer with boat still sitting in the road. My family was on board and I am alive and an accident didn't happen. I called a tow truck (took an hour to get to me) and charged me $520 for the tow. The tow truck driver said that he had to tow several chevrolet trucks with the same issue and it was a faulty fuel module. I had a mechanic run a diagnostic and the Code P129F commonly indicates a failure of the Fuel Pump Driver Control Module (FPDM) was the one coming out. I have read many customer experiencing the same issue. And in my case my trucks 3 year warranty expired November 2025 only 6 months ago.

Vehicle developed engine ticking/tapping noise followed by rough running and misfire condition. Independent repair facility performed engine teardown and found cylinder 4 exhaust camshaft lobe severely worn/damaged. Repair facility stated the exhaust roller follower/lifter needle bearings failed and fell out, causing the roller to seize and come off position, resulting in improper valve operation and cylinder malfunction. Vehicle lost proper engine performance and required major internal engine repair including camshaft, lifters/lash adjusters, and roller followers. Failure appears consistent with GM Preliminary Information bulletin PIP5847B for 2019–2024 Chevrolet Silverado/GMC Sierra 2.7L L3B engines describing exhaust roller follower bearing failure and camshaft damage. Concern is that sudden valvetrain failure could result in loss of power, engine failure, or unsafe driving condition.

While driving at highway speed with cruise control engaged, the vehicle experienced a sudden loss of propulsion. The engine began jerking and the vehicle rapidly decelerated from highway speed (50 mph) to 10–15 mph. The transmission appeared to disengage or shift to neutral around 10 mph, and the vehicle was unable to maintain speed, creating a hazardous situation in traffic. The vehicle then shut down and displayed a message to restart the engine along with a check engine light. When attempting to restart, the engine would not turn over properly and produced a loud clicking/struggling noise, similar to a failed or seized engine. The vehicle was towed and is currently awaiting diagnosis at a dealership. This failure occurred without warning and created a serious safety risk due to sudden loss of power while driving.

1. The fuel pump power control module on my 2022 Chevy Silverado failed. It was 38 months old and had 14,970 miles on it. I purchased it only 2 months ago. I believe the specific part number was 13554060. It was replaced with part number 13554821. The dealer retained--or more likely, disposed of--the old part. The cost of the repair was $762.87. 2. I was driving on Rt. US 20 in Toledo, Ohio. My truck experienced a sudden loss of power without warning. The vehicle stalled and would not restart. I had to call a tow truck. The truck was towed to Ballas Buick, where the part was replaced. 3. There was a voluntary recall of other vehicles that utilize this same part, so the manufacturer should be aware of the flaw in this component. The recall number is N252516900. 4. No warning light came on before the vehicle stalled, stranding me on the road. I had just enough of a sense of the impending failure to pull to the side of the road.

Year: 2022 Make: Chevrolet Model: Silverado 1500 Engine: 2.7L TurboMax (L3B) VIN: [XXX] Mileage at Failure: 119,139 Description of Problem: 2022 Chevrolet Silverado 1500 2.7L L3B TurboMax engine is completely inoperable due to Cylinder 4 exhaust roller follower failure causing exhaust camshaft failure and bent exhaust valves. Vehicle shakes severely, will not accelerate, check engine light on, and has gone into limp mode. Diagnostic codes P0304 (Cylinder 4 misfire) and P2101 (electronic throttle actuator fault triggered by engine shaking and limp mode) were recorded. All external components including spark plugs, coils, and injector harnesses were inspected and ruled out as causes. Failure is confirmed mechanical and internal. This failure was diagnosed and documented in writing by an authorized Chevrolet dealership on March 12, 2026 (Repair Order XXX, Service Advisor [XXX] ). The dealer's written estimate states verbatim: "Failed Cylinder 4 exhaust roller follower failure causing exhaust camshaft failure and bent exhaust valves. Cylinder head replacement required to correct this concern. Direct cause of engine noise and misfire condition." Dealer repair quote: $10,371.34. A second independent shop confirmed the same failure and cited Active Fuel Management (AFM) and Direct Fuel Injection (DFI) as known contributing design factors in this engine's oil consumption and internal wear pattern. That shop quoted between $11,876.88 and $14,897.35. This is a known pattern in the L3B engine platform. Consumer Reports has documented a 4% catastrophic failure rate in this engine. Multiple NHTSA complaints exist for this same failure across 2019-2022 model years. GM has issued technical service bulletins but has not issued a recall. General Motors was formally notified of this failure via certified mail and executive email on March 24, 2026. Vehicle is inoperable and poses a safety risk as the failure causes sudden loss of power and engine shaking w INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOI

I own a 2022 Chevy Silverado with a 6.2 liter engine. I had the original engine up until approx 80k in mileage when it failed, I was on a dark country road doing approximately 50mph and the propulsion system failed and the truck shut off, being a country road, I had minimum breaking and minimal steering. I had my [XXX] son in the car, we ended up in a culvert and I scraped either a large rock or a piece of concrete that sometimes line culverts, it did damage. At the time, until recently, I had no idea I should report this. I did know that GM had issued a recall and I believed the engineer would be covered, which it was. I never reported the damage to insurance as I didn't want my ins to go up anymore, so I have not fixed it yet. My [XXX] old was scared beyond belief. Anyhow, Williams Chevy in Elkton, Md replaced the engine free of any cost. I believe the dates are approx to be 9/26 to 10/25/ 2025.On or about 11/25 or 26th 2025, with approx 2k miles on the newly installed 6.2 liter engine, while traveling with my [XXX] son, I experienced another catastrophic engine failure.This time we were traveling on 896 in Delaware and rt 40. While crossing over, the car cut off completely again while traveling at 50mph. We barely avoided a collision on the other side of the intersection with merging traffic, I applied the Manuel breaks along with the power steering was out too. My spouse was angry that GM is still doing this knowing this could be the result.Upon the 2nd installation, I dropped the truck off on the above date. It took until 1/5/26 bor approx 1/9/26.On approx 2/12/26 I had the oil changed at a local jiffy lube. This was conducted at 3400 miles, less than the manufacturer suggests with the new 40w oil. Anyhow, yet again, my truck had zero rewarding on the dipstick. I have paperwork for both engine installs and the jiffy lube paperwork documenting the no reading on the dip stick.I am a disabled veteran and this is an unsafe and unreliable fix from GM.

On January 16, 2025, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE25001 after receiving complaints and field reports concerning engine failures in MY2019-2024 GM’s full-size truck and SUV T1XX platform equipped with the L87 6.2L V8 engine. These complainants alleged engine bearing failures resulting in knocking and growling noises from the engine’s bottom end and in some cases more severe consequences such as broken connecting rods leading to engine damage, or engine failure. If the engine fails during vehicle operation, the vehicle will lose propulsion, increasing the risk of a crash. On April 24, 2025, GM issued recall 25V-274 to address the concern with L87 engines produced between March 1, 2021, and May 31, 2024. GM cited the root cause as a supplier manufacturing and quality issues. GM’s recall remedy will be either an oil change to an oil with a different viscosity or engine replacement depending on the results of the remedy inspection procedure. To date, ODI has received 1,157 allegations of engine bearing failure. GM submitted 55,464 reports in total, with 29,752 unique VINs. ODI continues to receive allegations of L87 engine failures which fall outside of the scope of recall 25V-274. Based on GM’s recall, ODI will close this PE. NHTSA will continue to investigate complaints of engine failure outside the scope of recall 25V-274 as part ofEngineering Analysis (EA25007).
