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 55,000 miles; the figures below show which parts of the car run ahead of that and which run behind.

The brakes account for 18.4% of complaints (340 reports, 195 of them with a mileage figure), with a median of 62,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 45,000 and 81,314 miles.

The electrical system accounts for 12.2% of complaints (226 reports, 114 of them with a mileage figure), with a median of 53,750 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 22,000 and 74,000 miles.

The transmission and driveline accounts for 12.2% of complaints (225 reports, 73 of them with a mileage figure), and it fails late — a median of 80,000 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 12,996 and 104,000 miles.

Problems owners could not categorise accounts for 10.6% of complaints (196 reports, 92 of them with a mileage figure), with a median of 45,530 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 27,330 and 60,000 miles.

The engine accounts for 8.1% of complaints (149 reports, 57 of them with a mileage figure), with a median of 52,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 12,000 and 85,000 miles.

The steering accounts for 6.4% of complaints (119 reports, 72 of them with a mileage figure), with a median of 49,950 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 29,000 and 84,000 miles.

Differences between model years

Within this generation, complaint volume is not constant across model years. The 2015 model year drew the most — 892 complaints — while 2020 drew the fewest at 68. The median year sits at 197.

That makes 2015 an outlier: roughly 4.5 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 seat belts (4), the transmission and driveline (3), the steering (3). 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 1,845 complaints filed against this generation, 96 reported a crash; 6 reported a fire; 83 reported an injury; 3 reported a fatality. Crash-involved reports represent 5.2% 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 28,000 and 81,314 miles, with a median of 55,000. 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 53,750, 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.
