What stands out
Engine accounts for 31% of every owner complaint on file for this vehicle — the dominant problem area across 4 categories tracked.
The failure pattern owners describe
Twenty-two owners report catastrophic engine failures in 2025 Chevrolet Silverados, most striking at low mileage. Thrust bearing failures dominate the complaints—engines shut down suddenly at interstate speeds without warning lights, leaving drivers coasting to shoulders or stalled in traffic. One owner lost power in an intersection with family aboard; another's family narrowly avoided a 30-foot drop. Owners report being stranded 10 miles from home, an hour into highway drives, even on camping trips with children.
A few fail differently. One 6.2L piston exploded. Another's engine caught fire under the hood. Oil pump failure, oil pressure solenoid sticking, and a dangerous auto-stop feature that engages without clear warning round out the list.
The kicker: owners confirm GM published a technical service bulletin in September 2025 for this exact engine. Dealers are backordered on replacement engines for 3 to 6+ months due to high failure volume. One owner noted he was sold the truck at month's end, after the bulletin was public. Another received a remanufactured engine and immediately got a check engine light. One owner is watching metal debris accumulate in his oil at 21,000 miles—identical symptoms to his previous Chevy that grenaded.
No owner reports being warned. No owner says the problem was disclosed at purchase. GM declined to investigate the engine fire.

Failure modes owners describe
Thrust bearing failure
Crankshaft thrust bearing fails, causing catastrophic internal engine damage and sudden loss of power without warning. Multiple owners report this failure at various mileages. One dealer confirmed the failure matched a GM technical service bulletin published in September 2025, indicating a known issue with the Duramax 3.0 engine.
When: 5,624 miles; 9,000 miles; 33,000 miles; under 10,000 miles in some cases; no clear pattern by mileage
Symptoms owners cite: Sudden engine shutdown without warning; No check engine lights prior to failure; Loud noise from engine compartment before failure; Engine stalls and loses power immediately; Whining sound from engine that gets progressively louder over seconds
Codes mentioned: Thrust bearing failure confirmed by dealership diagnosis
Repairs/costs cited: Engine replacement required. Owners report replacement engines and turbos on back order for 3–6+ months or longer due to high volume of failures. One owner received a remanufactured engine as replacement.
Recalls/TSBs owners mention: GM technical service bulletin published September 2025 for Duramax 3.0; NHTSA Campaign Number 25V274000 (ENGINE AND ENGINE COOLING) referenced for 6.2L engine recall in previous model years. No disclosure of known issues to owners before purchase. No communication regarding how replacement engines address the original failure cause.
Connecting rod bearing failure
Connecting rod bearings fail, causing engine seizure. Owner attributes partial responsibility to low-viscosity motor oil (0W-20 synthetic) required by manufacturer and poorly engineered fuel management system.
When: 5,750 miles
Symptoms owners cite: Engine seizes
Codes mentioned: Connecting rod bearing failure
Repairs/costs cited: Engine, cooling system, and oil cooling system replaced under warranty with a similar engine.
Piston failure
Piston explodes or fails catastrophically. Owner reports the 6.2-liter engine was under recall for previous model years (NHTSA Campaign 25V274000) and experienced the failure listed in that recall.
When: 9,000 miles
Symptoms owners cite: Abnormal sound from engine compartment; Vehicle stalls
Codes mentioned: Piston explosion diagnosed at dealership
Repairs/costs cited: Engine replaced with remanufactured engine.
Recalls/TSBs owners mention: NHTSA Campaign Number 25V274000 (ENGINE AND ENGINE COOLING) applies to 6.2L engine in previous model years.
Engine oil pressure control solenoid valve failure
Oil pressure control solenoid valve sticks in the off position, triggering reduced acceleration mode and requiring full engine replacement at very low mileage.
When: 3,307 miles
Symptoms owners cite: Dashboard message 'reduced acceleration mode drive with care'; Reduced engine power
Codes mentioned: P06DD (Engine Oil Pressure Control Solenoid Valve Stuck Off)
Repairs/costs cited: Full engine replacement required. Engine on back order with no timeframe available.
Oil pump failure
Oil pump fails, causing engine to burn up. Owners report low oil pressure warnings before total engine failure.
When: Unknown mileage; failure occurred after owner noticed lower acceleration and received low oil pressure warning
Symptoms owners cite: Lower acceleration than usual; Check engine light; Surging and loss of power; Dashboard message 'power decline'; Dashboard message 'low oil pressure turn engine off'; Engine burns up
Codes mentioned: Oil pump fault (diagnosed by dealership)
Repairs/costs cited: Complete engine replacement.
Engine fire
Engine catches fire under the hood, resulting in total loss of vehicle. Fire department extinguished flames but did not investigate cause. Manufacturer refused to investigate.
When: Approximately 7,000 miles; also reported at 2,000 miles during startup in another case
Symptoms owners cite: Fire starts under hood; Flames visible from both sides of hood
Repairs/costs cited: Vehicle total loss.
Recalls/TSBs owners mention: GM refused to investigate; directed owner to work through insurance company.
Auto-stop malfunction and unsafe design
The auto-stop feature engages automatically on every engine start with minimal visual indication (only a small light on the switch). Feature shuts off engine without operator command and restart delay can be several seconds, creating unsafe situations. Engine may not restart if operator releases and reapplies brake pressure. When restart is late, engine may surge and vehicle lurches into traffic.
When: Occurs on every engine start
Symptoms owners cite: Auto-stop feature engages automatically without operator command; Delayed engine restart of several seconds; Engine restart failure if brakes are reapplied before restart; Engine surge and vehicle lurch when restart is delayed; Minimal warning indication (only small light on switch); No amber warning light on dashboard
Injector failure (post-replacement engine)
Injector #3 fails shortly after complete engine replacement, resulting in check engine light and reduced power warning. Vehicle returned to dealer after 10 miles.
When: 10 miles after complete engine replacement
Symptoms owners cite: Check engine light; Dashboard message 'reduced power service DPF system'
Codes mentioned: P0302
Repairs/costs cited: Injector #3 replaced.
Reduced acceleration/limp mode triggered by various causes
Vehicle enters limp mode or reduced acceleration mode under normal driving conditions, triggered by oil pressure, DPF, or other sensor faults. Owners experience dangerous loss of power on highways.
When: Various mileages; at 75 MPH on highway in one case; after about 1 hour of normal driving in another
Symptoms owners cite: Reduced speed mode on highway; Limp mode activation; Dashboard warning messages; Significant power loss while driving; Unable to safely stop; Dangerous swerving required by other vehicles
Codes mentioned: P06DD (oil pressure solenoid), Low oil pressure codes, DPF-related codes
Repairs/costs cited: Varies by root cause; oil pressure solenoid replacement, injector replacement, or full engine replacement required.
Metal debris in oil/bearing wear
Owner with 2020 Chevy (piston rod failure) traded for 2025 model with L87 6.2 motor. New truck at 21,000 miles exhibits rougher idle, excessive oil consumption between changes, and metal debris in oil and filter—signs of internal bearing or component wear similar to previous failed engine.
When: 21,000 miles on new truck; symptoms emerging at this mileage
Symptoms owners cite: Rough idle; Excessive oil consumption between oil changes; Metal debris in oil; Metal debris in oil filter
Repairs/costs cited: No repair completed; owner concerned engine will fail similar to previous vehicle.
Engine transmission lockup after failure
Following catastrophic engine seizure from bearing failure, the electronically controlled transmission refused to shift gears or move into neutral to allow vehicle to be towed. Vehicle had to be dragged rather than pushed.
When: After connecting rod bearing seizure at 5,750 miles
Symptoms owners cite: Transmission will not shift gears; Transmission will not move into neutral; Vehicle cannot be pushed or towed normally
Repairs/costs cited: Vehicle had to be dragged rather than rolled onto tow vehicle.
