Honda Civic 2016–2021

10th generation · FC (sedan) / FK (hatchback, Type R FK8) · 4,033 complaints, 1,474 with mileage

Owners filed 4,033 complaints with NHTSA about the 2016–2021 Honda Civic, and 1,474 of them record the mileage at which the failure happened. That is enough to show not just what fails, but when.

35% of failures fall within the first 12,000 miles. Failures clustered that early usually indicate a design or manufacturing problem rather than wear.

The most-reported areas are the steering (27.2% of complaints, typically around 41,184 miles), problems owners could not categorise (15.8% of complaints, typically around 31,000 miles), the electrical system (9.0% of complaints, typically around 18,000 miles).

14 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 25,000 miles; the figures below show which parts of the car run ahead of that and which run behind.

The steering accounts for 27.2% of complaints (1,096 reports, 253 of them with a mileage figure), and it fails late — a median of 41,184 miles, considerably beyond the vehicle's overall median. That pattern is consistent with normal service life rather than a defect, though it matters for anyone buying an example already near that mileage. The middle half of these reports falls between 24,000 and 59,000 miles.

A single system taking 27.2% of all complaints is a concentration worth noting. It means that for this generation, most of what owners reported came back to one area of the car rather than being distributed across many small faults.

Problems owners could not categorise accounts for 15.8% of complaints (639 reports, 217 of them with a mileage figure), with a median of 31,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 7,500 and 48,000 miles.

The electrical system accounts for 9.0% of complaints (364 reports, 163 of them with a mileage figure), with a median of 18,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 4,500 and 40,000 miles.

The engine accounts for 6.5% of complaints (263 reports, 137 of them with a mileage figure), with a median of 19,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 5,700 and 43,000 miles.

The fuel and propulsion system accounts for 5.9% of complaints (238 reports, 46 of them with a mileage figure), and it fails early — a median of 13,899 miles, well before the vehicle's overall median. Failures clustered this far below the rest of the car usually point to a design or manufacturing problem rather than wear, because wear does not selectively target one system on low-mileage examples. The middle half of these reports falls between 2,711 and 30,000 miles.

The brakes account for 5.1% of complaints (206 reports, 120 of them with a mileage figure), and they fail early — a median of 15,000 miles, well before the vehicle's overall median. Failures clustered this far below the rest of the car usually point to a design or manufacturing problem rather than wear, because wear does not selectively target one system on low-mileage examples. The middle half of these reports falls between 5,500 and 40,000 miles.

Differences between model years

Within this generation, complaint volume is not constant across model years. The 2016 model year drew the most — 1,363 complaints — while 2021 drew the fewest at 205. The median year sits at 648.

That makes 2016 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 14 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 fuel system (3), the airbag system (2), equipment (2). 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 4,033 complaints filed against this generation, 195 reported a crash; 32 reported a fire; 113 reported an injury; 1 reported a fatality. Crash-involved reports represent 4.8% 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, an early-failure pattern is comparatively good news on a used example: 35% of the reported failures occur in the first 12,000 miles, which on a car of this age means they have already happened or they were never going to. Service history matters more than mileage here.

On inspection, the steering and problems owners could not categorise are where this generation's reports concentrate, so those are the areas worth a specific look. Problems owners could not categorise in particular shows a median failure mileage of 31,000, 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

Engine (1.5L turbo) 2016-2018 (1.5L turbo)

Fuel dilution of engine oil - unburned gasoline accumulates in the crankcase on short trips in cold weather, raising oil level, thinning viscosity and producing a fuel smell. Honda extended powertrain warranty coverage to 6 years with no mileage limit on affected cars and issued software and HVAC calibration updates.

Fuel pump 2019-2020

Denso low-pressure fuel pump impeller can crack and deform, causing the pump to fail and the engine to stall without warning; NHTSA recall covering 2019-2020 vehicles.

Air conditioning 2016-2018

A/C condenser leaks causing loss of cooling; subject of extended warranty coverage and litigation.

Electrical 2016-2018

Parasitic 12V battery drain producing repeat no-start conditions, addressed through software updates.
