2019 Chevrolet Silverado 1500

The Office of Defects Investigation (ODI) has received 1,157 reports of engine bearing failure failures in the L87 6.2L engine produced by General Motors (GM). Of the 1,157 reports received, 173 are outside of the scope of recall 25V-274. These engines are installed in Model Years (MY) 2019–2024 Chevrolet Silverado 1500 and GMC Sierra 1500, and 2021-2024MY Chevrolet Suburban and Tahoe, GMC Yukon/Yukon XL, and Cadillac Escalade/Escalade ESV vehicles. The subject engine failures were investigated as part of a Preliminary Evaluation (PE25001).  GM determined that these engine failures were due to multiple supplier manufacturing and quality issues. GM issued recall 25V-274 to address the supplier manufacturing and quality issues produced between March 1, 2021, and May 31, 2024. Based on the issuance of recall 25V-274, NHTSA has closed PE25001. ODI continues to receive a significant number of reports of engine failure in vehicles outside the scope of 25V-274.  This presents a potential safety risk that warrants further investigation.  ODI is opening this Engineering Analysis (EA) to further evaluate the scope and severity of the potential problem and to fully assess the potential safety-related issues of vehicles built outside the recall scope. To review the ODI reports cited in the Opening Resume ODI Report Identification Number document, go to NHTSA.gov.

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).

I parked truck in driveway and an hour later it would not start. It was towed to 87 Garage where they installed new starter. Mechanic called and said starter was not problem, then engine seized. Need a new engine. This could be catastrophic if it seized while driving. GM tells me take to dealer an pay diagnostic fee to help. I’ve read a recall maybe coming issue by NHTSA after GM hands over all of these reports on 13 November 2026. My engine seized 31 October 2026. I’m waiting for new engine replacement cost estimated 15-20,000.00 from 87 Garage.

My 2019 Chevrolet Silverado 1500, VIN [XXX], with 137,640 miles, experienced repeated Battery Saver warnings, severe charging voltage fluctuations dropping as low as 9 volts, and intermittent reductions in engine power and RPM while driving. Upon inspecting the alternator, I discovered severe overheating at the positive battery cable (B+) connection. The plastic insulation surrounding the alternator terminal had melted away, and the charging cable insulation was brittle and heat-damaged. I have photographs documenting the damage. I reviewed GM safety recall N192273510 (NHTSA 19V888), which describes loose alternator B+ connections causing intermittent electrical failures, arcing, overheating, possible engine stalling, and fire hazards. The symptoms and physical damage described in this recall closely match what occurred on my vehicle. However, both Chevrolet and NHTSA indicate that my VIN is not included in the recall. I contacted GM Customer Assistance and received case number [XXX] after requesting escalation. GM advised that my case would not become active until a dealership inspected the vehicle. A Chevrolet dealership quoted $1,345 to replace the alternator and positive charging cable without physically inspecting the truck. Towing and diagnostic expenses are estimated at an additional $400. I am concerned that other 2019 Silverado vehicles excluded from recall 19V888 may experience the same potentially dangerous electrical failure. I request that NHTSA investigate whether the existing recall population should be expanded to include additional affected vehicles. The vehicle has not been repaired, and the damaged components remain available for inspection. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Incident

Nov 1, 2026

While operating at cruising speed of about 50 MPH, I passed a slower-moving vehicle and experienced a catastrophic failure of the motor. I was able to limp the vehicle a short distance to a local dealership where I was informed that the motor needed to be replaced at 128K miles. I was further advised that this is a long-standing issue with this motor (L87 6.2L) related to the fuel management system. While I was going over the quote for motor replacement ($9,143.18), a similar vehicle with a 5.3L motor was being worked on for the same issue. This forced me to obtain a loan and extended the amount of time that it will now take me to pay the vehicle off.

The pickup was being driven in a parking lot when all the warning lights came on. Oil was found under pickup and it would no longer start. It was towed to nearest GM dealer where they informed that engine had seized and needed to be replaced. Pickup has been traded for a different vehicle so I no longer own this pickup.

2019 Silverado 1500 6.2L, #3 lifter/cylinder collapsed while just getting up to highway speed on [XXX] near [XXX], Wagonmound NM, on Saturday, [XXX]; heard a LOUD bang, followed by message center stating stabilizer control was turned off, followed by FLASHING check engine light. We were towing “dry” Northwood 17k Nash, with our three dogs. As soon as we realized the truck was in the danger zone, we pulled over as quickly as possible. Both truck and trailer had to be towed 40 mi south to Las Vegas NM. The driver dropped our trailer at a local RV park and dropped our Silverado at Las Vegas Diesel Repair. We had to leave the truck in Las Vegas as having it hauled to Longmont Colorado, where we live, would have been too expensive. It’s been seven weeks; getting a new, rebuilt, deleted Jasper engine was my only choice. We stayed through the weekend, had to rent a UHAUL box truck to get home, as car rental was not a one-way option; this cost $500 and the tow was $600, insurance reimbursed $400. We were stranded on [XXX], with three dogs for well over an hour, so dangerous for us. I feel fortunate that the truck didn’t start on fire due to the fact that raw fuel was dumping into the catalytic converter due to the lifter collapsing into the CAM shaft. AS I HAVE COME TO LEARN, GM IS PROFOUNDLY AWARE OF THE LIFTER PROBLEM, ESPECIALLY IN THE YEAR/MAKE/MODEL OF MY TRUCK AND HAS MORBIDLY FAILED TO NOTIFY OWNERS OF THE DANGEROUS CONDITION THIS PRESENTS. IT’s my understanding that there is a class action lawsuit against GM in the works and I WILL be in on that action. We’re talking 100’s of 1000’s owners that are unaware of the danger their vehicle presents…I didn’t know and I researched recalls on my truck BEFORE I bought it used with 92,000 miles a couple of years ago. It has approximately 123,000 on the engine that’s being replaced to the tune of $15,000~. Virtually everything under the hood has to be replaced, final bill is pending; $7000k to start work INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (F

This document assists GM dealer technicians with diagnosing torque converter concerns to ensure torque converter replacement is necessary. The torque converter part number will be placed on order restriction, and the technician will be asked to follow 25-NA-148 before requesting a part through PQC.

This Preliminary information communicates that it is normal for the tailgate to drop faster than it used to after the GM Accessory Kicker Audio System is installed.

This PI communicates information that Engineering has released an updated Trailer Lighting Control Module to correct false Service Trailer Turn Signal Message when operating the power tailgate with no trailer connected.

• Improvements to OnStar functionality.

General Motors has decided to conduct a Voluntary Emission Recall. Certain vehicles may have a condition that could cause a small exhaust leak at the catalytic converter inlet. Dealers are to replace the catalytic converter inlet clamp and to inspect the catalytic converter – replacing it if damage is observed. The repairs will be made at no charge to the customer.
