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 39,000 miles; the figures below show which parts of the car run ahead of that and which run behind.

Body structure accounts for 18.6% of complaints (440 reports, 211 of them with a mileage figure), with a median of 50,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 22,000 and 86,000 miles.

The airbag system accounts for 15.3% of complaints (363 reports, 82 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 21,304 and 83,000 miles.

Problems owners could not categorise accounts for 10.8% of complaints (256 reports, 127 of them with a mileage figure), with a median of 49,600 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 20,000 and 78,000 miles.

The electrical system accounts for 9.4% of complaints (222 reports, 154 of them with a mileage figure), with a median of 35,450 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 9,300 and 72,100 miles.

The transmission and driveline accounts for 6.4% of complaints (152 reports, 77 of them with a mileage figure), and it fails late — a median of 75,656 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 30,000 and 100,000 miles.

The wheels account for 4.3% of complaints (103 reports, 57 of them with a mileage figure), with a median of 32,888 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 22,000 and 75,706 miles.

Differences between model years

Within this generation, complaint volume is not constant across model years. The 2011 model year drew the most — 814 complaints — while 2020 drew the fewest at 48. The median year sits at 205.

That makes 2011 an outlier: roughly 4.0 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 36 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 (7), equipment (7), 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 2,368 complaints filed against this generation, 147 reported a crash; 46 reported a fire; 164 reported an injury. Crash-involved reports represent 6.2% 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 13,000 and 75,000 miles, with a median of 39,000. There is no single mileage threshold to watch, which means condition and maintenance records are more informative than the odometer.

On inspection, body structure and the airbag system are where this generation's reports concentrate, so those are the areas worth a specific look. Body structure in particular shows a median failure mileage of 50,000, 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.
