2019 Chevrolet Silverado 1500

Vehicle suffered a premature catastrophic failure of the Dynamic Fuel Management, lifter and camshaft assembly at 80k miles

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)

The contact owns a 2019 Chevrolet Silverado 1500. The contact stated that while driving approximately 25 MPH, the check engine warning light started flashing. The vehicle was taken to an independent mechanic, where the engine was disassembled and the vehicle was diagnosed with engine lifters failure, causing engine failure. The contact associated the failure with NHTSA Action Number: EA25007 (Engine, Engine and Engine Cooling). The vehicle was not repaired. The manufacturer was notified of the failure by phone. The failure mileage was approximately 70,000.

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.

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.

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 (FOIA), 5 U.S.C. 552(B)(6)
