There are 50 owner-reported engine complaints for the 2023 Chevrolet Silveradoin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
I'm reporting a 5mpg fuel economy reduction immediately following the 6.2L L87 engine recall (NHTSA #24V795000). I use 93 octane and monitor my fuel mileage consistently. I bragged about my fuel economy in my 6.2l until after the recall was applied. This is going to cause a financial hardship as I'm on fixed income after Servicing 29 years in the Army and 100% disabled. There is no other reason my mpg should have changed as my driving habits have not.
The contact owns a 2023 Chevrolet Silverado 1500. The contact stated that while driving at 70 MPH, the vehicle hesitated while depressing the accelerator pedal. The vehicle continued to lose power with a huge cloud of white smoke coming from under the hood. There was no warning light illuminated. The contact pulled off to the shoulder of the roadway, and the vehicle shut off unexpectedly. Due to the failure, the vehicle was towed to the dealer and was diagnosed with engine failure. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was approximately 20,000.
The contact owns a 2023 Chevrolet Silverado 1500. The contact stated that the engine failed after the vehicle was repaired under NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling). The contact stated that while driving 70 MPH, the vehicle lost motive power. The message "Hot Oil Shutting Down" was displayed. The contact coasted to the side of the road, and the vehicle was towed to the dealer. The dealer determined that the engine had failed and needed to be replaced. The vehicle was not yet repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 36,500.
While driving on the freeway without warning, my engine stopped working. My vehicle was towed to the Chevy dealership where they confirmed that I was the latest victim of the ongoing engine failure problem with the 6.2 L engine. There was no warning, no sign that I had a problem. My engine just simply stopped working on a busy freeway. I was barely able to make it to the shoulder where I had merging traffic coming on the freeway behind me. I’m deeply concerned that Chevy will replace it with the same faulty engine and I will be put in the same danger situation again in the future.
I am reporting another engine failure on the 6.2L L87. This engine passed the initial recall testing and the oil was changed to 0W40 on September 30, 2025. However, my engine in my 2023 LT Trail Boss started knocking on Friday, March 20, 2026 (at 22,500 miles) after I picked up my children from school. Thankfully it started as I pulled into my driveway with them so they weren’t in any danger. No loss of power on the truck or warning lights visible. However, it was loud enough and odd enough for my [XXX] olds to even notice the sound in the cab. It was dropped off at the dealership on that Saturday morning and the GM dealership was finally able to look at it on Wednesday, March 25th and confirmed what was expected. The advisor stated the engine will need to be replaced due to the engine heading towards bearing/crankshaft failure. I am still currently without my truck as of today (April 4th) with no repair date in sight. I will say that the dealership service advisor has been very good about communicating about its status. However, he stated that he has had no luck finding an new engine and is unable to give a timetable in getting one. He did offer to start a PO for a rental car through enterprise. He stated they are not giving loaners, but could get a rental car. He also stated that it would not be a truck due to GM only giving $50 per day towards a rental. So here I sit currently without my truck. I see multiple reports about the engines being on back order and even the replacement engines are failing within the fist 500 miles. Some reports indicating they are on the third or fourth engine. Something needs to done about getting these trucks bought back by GM. They have clearly failed with this engine and are replacing the failed engines with the same thing! It is a well documented manufacturing flaw and design! I am thankful it occurred near my home. I would not have been happy with a catastrophic failure on a highway with my [XXX] old children in the truck!!

The vehicle is currently exhibiting a loud, rhythmic metallic ticking/tapping noise from the top of the engine. This is a known precursor to a sudden, catastrophic loss of motive power as documented in GM Service Bulletins PIP5847A and PIP6101. The cause is attributed to manufacturing debris within the hydraulic valve lash adjusters, which prevents proper lubrication and causes valvetrain desynchronization. This defect leads to severe engine misfires (DTC P0300), "Reduced Engine Power" mode, and potential engine seizure. 1. Component/System: The 2.7L L3B Engine Valvetrain / Hydraulic Lash Adjusters. The vehicle is available for inspection. 2. Safety Risk: The audible ticking indicates imminent mechanical failure. This defect causes sudden and unexpected loss of motive power at highway speeds. Driving in this condition puts me at extreme risk of being stranded in active traffic or losing power while merging/passing, creating an immediate risk of high-speed rear-end collisions. GM is aware of this debris-related defect via TSBs but has not issued a safety recall to prevent the resulting power loss. 3. Dealer Confirmation: Yes, confirmed by Chevrolet dealer on 3/18/26. The dealer knows about this particular issue, and decided not to act. 4. Inspection History: Inspected by authorized Chevrolet service technician. 5. Warning Symptoms: Loud metallic ticking/clacking that increases with engine RPM. This is a known precursor to a sudden, catastrophic loss of motive power as documented in GM Service Bulletins PIP5847A and PIP6101.

RE: FORMAL COMPLAINT–RECALL FRAUD & VIN TAMPERING SUBJECT: Falsified Recall N252494000 & 18 U.S.C. § 511 Violations VEHICLE: 2023 Chevy Silverado (VIN: [XXX] ) INCIDENT: March 7, 2026 FROM: [XXX] | [XXX] I am reporting severe Federal Recall Fraud and VIN tampering by Kunes Auto Group (WI). GM records and physical evidence prove Kunes falsified Safety Recall N252494000 (L87 Loss of Propulsion) and sold an illegally rebuilt wreck with mismatched VINs. 1. Falsified Recall: On 4/9/2024, Kunes logged a PicoScope Inspection marking the recall "Passed" (Trans #XX-XXX). The NHTSA remedy requires installing a 0W-40 oil cap/flush. When the engine seized on 3/7/2026, it still had the factory 0W-20 cap. Kunes billed GM for a safety remedy never performed. 2. Concealed Defects: Despite the "Closed" recall, the truck exhibited L87 defect symptoms. I brought it to Kunes three times (Oct 2025 - Feb 2026). They dismissed the warnings and released the truck as safe. 3. VIN Fraud (18 U.S.C. § 511): The 2023 truck has 2025-stamped frame/axle parts. Holz Motors (authorized GM) blacklisted it on 3/6/2026 (RO #1583470), stating in writing: "DUE TO... MISMATCHED VINS DOOR TO DASH, SALVAGED REAR AXLE... HOLZ WILL NOT BRING THIS TRUCK IN." 4. Highway Failure: On 3/7/2026, the L87 motor suffered total Loss of Propulsion at 70 MPH in traffic. The sudden loss of power steering/braking nearly caused a multi-vehicle fatality. REQUESTED ACTION: 1. Audit Kunes’s PicoScope data for the 4/9/2024 transaction. 2. Investigate remedy fraud (missing 0W-40 cap). 3. Investigate tampered/mismatched VINs and off-the-books rebuild. 4. Sanction dealer for fraudulent safety certifications. I declare under penalty of perjury these statements are true.
