Chevrolet Silverado 1500 2014–2018

3rd generation (K2XX) · K2XX · 6,368 complaints, 3,743 with mileage

Owners filed 6,368 complaints with NHTSA about the 2014–2018 Chevrolet Silverado 1500, and 3,743 of them record the mileage at which the failure happened. That is enough to show not just what fails, but when.

Failures are spread across the mileage range, with the middle half between 29,000 and 79,000 miles. The median is 52,000 miles.

The most-reported areas are the brakes (17.8% of complaints, typically around 55,000 miles), the electrical system (13.3% of complaints, typically around 54,786 miles), the transmission and driveline (13.2% of complaints, typically around 51,000 miles).

19 recall campaigns cover this generation.

Which systems, and when

Complaints about this generation are not spread evenly across the vehicle, and the systems that generate the most of them do not all fail at the same point in a car's life. The median failure across all systems here is 52,000 miles; the figures below show which parts of the car run ahead of that and which run behind.

The brakes account for 17.8% of complaints (1,132 reports, 702 of them with a mileage figure), with a median of 55,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 40,000 and 75,000 miles.

The electrical system accounts for 13.3% of complaints (846 reports, 448 of them with a mileage figure), with a median of 54,786 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 35,000 and 80,200 miles.

The transmission and driveline accounts for 13.2% of complaints (839 reports, 387 of them with a mileage figure), with a median of 51,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 13,000 and 96,000 miles.

The steering accounts for 12.2% of complaints (774 reports, 529 of them with a mileage figure), with a median of 55,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 35,000 and 85,000 miles.

The engine accounts for 9.5% of complaints (603 reports, 309 of them with a mileage figure), with a median of 56,500 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 33,000 and 80,200 miles.

Problems owners could not categorise accounts for 8.5% of complaints (542 reports, 292 of them with a mileage figure), with a median of 49,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 24,000 and 68,650 miles.

Differences between model years

Within this generation, complaint volume is not constant across model years. The 2014 model year drew the most — 2,196 complaints — while 2018 drew the fewest at 748. The median year sits at 1,046.

That makes 2014 an outlier: roughly 2.1 times the median year of this generation. A single year standing that far apart usually reflects either a first-year issue that was later corrected, or a component change introduced for that year. Anyone shopping this generation has a straightforward reason to prefer a different year, all else being equal.

Recalls and what they cover

NHTSA records 19 recall campaigns covering vehicles in this generation. A recall means the manufacturer or the regulator concluded there was a safety defect or a standard was not met, and that a free remedy is owed to owners — including second and later owners.

The campaigns cluster around the airbag system (6), the seat belts (4), the hydraulic brake circuit (4). Repeated recalls against the same area of the car generally mean the first remedy did not fully resolve the underlying problem.

Recall status is specific to the individual vehicle, not the model. Checking a VIN against NHTSA's lookup is free and takes under a minute, and it is the only way to know whether a particular car has had the work done.

Reported severity

Of the 6,368 complaints filed against this generation, 319 reported a crash; 88 reported a fire; 159 reported an injury; 15 reported a fatality. Crash-involved reports represent 5.0% of the total.

These are owner-reported outcomes, not verified investigations, and they are not adjusted for how many of these vehicles are on the road. They are included because the distinction between a fault that strands a car and a fault that causes a collision is the one that matters most, and it is not visible in a complaint count alone.

What this means if you are buying one

For a buyer, failures on this generation are spread rather than concentrated: the middle half falls between 29,000 and 79,000 miles, with a median of 52,000. There is no single mileage threshold to watch, which means condition and maintenance records are more informative than the odometer.

On inspection, the brakes and the electrical system are where this generation's reports concentrate, so those are the areas worth a specific look. The electrical system in particular shows a median failure mileage of 54,786, which gives a concrete number to compare against the odometer of any car you are considering.

None of this is a substitute for a pre-purchase inspection on the individual car. Aggregate patterns describe a population; the example in front of you has its own history.

Documented problems

Transmission (8L90) 2015-2018

Torque-converter shudder and harsh 2-3 / 3-4 shifts traced to the original Dexron-VI fluid formulation; GM's fix was a flush to Mobil 1 Dexron HP fluid, with repeat failures common. Same defect family as the 8L45.

Engine (5.3L/6.2L AFM) 2014-2018

AFM lifter collapse on the deactivating cylinders, frequently taking out the camshaft; owner reports cluster around 100k-120k miles.

Engine (5.3L) 2014-2018

Continued excessive oil consumption on the Gen V L83, from piston-ring sealing and AFM oil management.

HVAC 2014-2018

A/C condenser and evaporator leaks causing loss of cooling, a high-volume complaint on this body.
