A spike years after the car went on sale usually means a part wearing out on schedule across the whole fleet — the kind of pattern no single owner can see from inside their own car.

NHTSA investigations into the 2024 Chevrolet Silverado 1500

An investigation is the step before a recall: the agency has seen enough complaints to look into a pattern itself. An open one means it thinks something may be wrong and nothing has been fixed yet.

Loss of motive power due to engine failure post recall remedy

On January 16, 2026, the Office of Defects Investigation (ODI) opened Recall Query RQ26001.  This investigation was opened to assess the remedy effectiveness of Recall 25V-274. ODI has received complaints alleging engine failure in vehicles after the recall remedy had been completed, whether that remedy involved an oil viscosity change or a complete engine replacement. General Motors (GM) issued Recall 25V-274 to address concerns of engine failure in the L87 engines produced between March 1, 2021 and May 31, 2024. GM cited the root cause as a supplier manufacturing and quality issue. GM’s reca...

Recalls on the 2024 Chevrolet Silverado 1500

A complaint is one owner's allegation. A recall is the point at which the manufacturer or a regulator agreed the defect is real and dangerous enough to fix for free — however old the car is.

United States — NHTSA

25V274000

ENGINE AND ENGINE COOLING:ENGINE:HARD PARTS INTERNAL/MECHANICAL

General Motors LLC (GM) is recalling certain 2021-2024 Cadillac Escalade and Escalade ESV, Chevrolet Silverado 1500, Suburban, and Tahoe, GMC Sierra 1500, Yukon, and Yukon XL vehicles equipped with a 6.2L V8 gas engine. The connecting rod and/or crankshaft engine components may have manufacturing defects that can lead to engine damage and engine failure.

Risk: Engine failure increases the risk of a crash.

24V626000

TRAILER HITCHES

OEM Systems, LLC (OEM) is recalling certain 2024 Chevrolet Silverado vehicles. The rear bumper mounting bracket may not be sufficient for towing, which can allow the towed trailer to detach from the vehicle.

Risk: A trailer that detaches from a vehicle while driving increases the risk of a crash.

Recalls cover specific build ranges, so check your own vehicle by VIN at nhtsa.gov/recalls or, in Canada, Transport Canada.

San Marcos, CA Crash

STEERING

I applied brake and pedal went straight to floor without any stopping. I had to steer into a ditch to avoid a collision resulting in more damage to steering system, frame, windshield and body. This was complete brake system failure and yes is available for inspection. I was in a very rural area at time and was able to avoid a collision however, if I had been in city or on highway it could have easily resulted in injury or fatalities. The problem is currently under federal investigation and has been widely reported as a serious problem which may soon result in widespread recall. The vehicle has not been inspected yet by dealership or anywhere else as it just happened 18 hours ago. There were no warning lights or chimes before the incident when pedal went to the floor. After incident dashboard lit up with warning lights including, Brake, ABS, Traction control, power steering, Collision system, Engine light, Steering Column and others. Truck speed limited to 43 mph. And pedal still goes to the floor without applying brakes.

SERVICE BRAKES

On Febuary 13th 2026 I was involved in a wreck where I re-ended another stopped vehicle. There was no warning light or automated braking executed. I braked hard but not soon enough.There was no malfunction warnings or lights displayed before (or after ) the accident showing it to be inoperative. It has been in to the dealer 3 times since. Yes it is available for inspection. Was told that it will not work if you have your foot on brake or accelerator by one technician. This truck use to brake for no reason even going 70 mph on highway. I am pretty sure GM has reprogramed to fix that issue leaving the sensitivitu so low it now does not work at all.

ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL:UREA INJECTION SYSTEM (DEF)

The contact owns a 2024 Chevrolet Silverado 1500. The contact stated that the vehicle had been experiencing inaccurate DEF gauge readings since the purchase, and the failure mostly occurred while towing a camper or trailer. The contact stated that while driving 70 MPH on the highway and hauling a camper, the message that the DEF tank was empty and needed to be refilled was displayed, and the vehicle went into LIMP Mode and decelerated to 35 MPH. The driver continued driving and pulled over to a safe location. The vehicle was taken to a dealer, where it was determined that the DEF tank needed to be replaced; however, the manufacturer denied authorization because the required preliminary procedures had not been completed. The manufacturer General Motors LLC was notified of the failure by phone. The failure mileage was approximately 4.

ENGINE

Original 6.2L engine was replaced subsequent to NHTSA Report 11724274 from Catatrophic engine failure on January 31, 2026 at 25,274 miles. Original engine was manufactured on May 30, 2024, but Silverado HC was manufactured on June 9, 2024, so it was not captured in existing NHTSA Campaign 25V‑274 and subsequent GM 6.2L Recall and is not currently included in expanded factory 10/150,000 powertrain warranty. Due to original catastrophic engine failure due to crank and connecting rod, covered transmission damage was discovered, truck is currently on third Torque Converter and Transmission has been out of truck for repairs to Valve Body and 4-10/reverse piston twice. Replacement 6.2L engine lasted 3,900 miles before exhibiting significant Lifter Tick Bank One/Driver Side, Tear down revealed failed lifter which wiped out a lobe on Cam. GM TAC refused engine replacement, instead replaced one Cam, 16 lifters and trays on Bank One. Drove truck for approximately 300 miles after repair and Engine began exhibiting significant knocking from bottom of engine, second replacement engine is now being installed. All routine maintenance and Warranty work has been performed and documented at GM certified Dealer Service Department.

POWER TRAIN

This vehicle is a 2024 Chevrolet Silverado 1500 featuring a 6.2L V8 engine and a 10 speed transmission, currently at 58,136 miles. The vehicle was experiencing a severe shudder. An official GM Technical Assistance Case (TAC) engineering case was opened on July 30, 2026 confirming a verified DFM cylinder deactivation or valve train malfunction. However, on August 21, 2026 the dealership falsified the repair log by printing ‘Concern Not Duplicated’ to the manufacturer, while physically installing an unapproved aftermarket Range Technology DFM Eliminator module into the vehicle’s engine harness to artificially override the factory emissions and cylinder deactivation programming to mask the mechanical failure. This vehicle is part of the active NHTSA Engineer Analysis EA26005, and the manufacturer’s dealer network is actively using unapproved third party hardware shortcuts to evade mandatory warranty repairs before the vehicle’s 60,000 mile factory powertrain limit expires. I called GM to report and request a warranty freeze and regional field engineer to go to a different dealership and was told they can’t freeze a warranty because the TAC was closed on August 28, 2026 as resolved even though it was not resolved.

ELECTRICAL SYSTEM

Check engine light repeatedly comes on. Take it in, multiple Chevy dealerships “fix” the errors such as fuel line pump 5x, gear shift issues, modules that went bad and various other issues. I Routinely take care of vehicle (oil changes, tire rotations and service when needed) This truck will randomly shut off while driving (stop and go traffic ) I was told to turn off the start/stop which I do every time I get in the truck. However it recently wouldn’t turn over after going through a car wash, it would try and try till I manually stopped it. It’s running rough now and I pray everyday the check engine light doesn’t come on or that it doesn't just shut off mid drive. This truck has been hell on wheels and I bought it with 10 miles on it. Bought it from AutoNation in 12/2023.

ENGINE

Not that anything has happened to my truck but im genuinely worried that something bad will happen with my motor. With it being the 6.2L L87 motor. My truck was manufactured july 2024 which is 2 months after Gm's cut off. I love the truck but im worried about going to and from work, what if i was to turn and this truck dies and i go into oncoming traffic? What about everyone else driving their own vehicles? I hope something is done because im really thinking about getting rid of this truck in fear of something bad happening. Thank you.
