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 37,000 miles; the figures below show which parts of the car run ahead of that and which run behind.

The engine accounts for 28.0% of complaints (369 reports, 53 of them with a mileage figure), with a median of 40,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 16,786 and 72,000 miles.

A single system taking 28.0% 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.

The transmission and driveline accounts for 12.8% of complaints (169 reports, 29 of them with a mileage figure), with a median of 40,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 27,000 and 69,000 miles.

The electrical system accounts for 11.2% of complaints (148 reports, 17 of them with a mileage figure), and it fails 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 2,502 and 45,844 miles.

The engine and its cooling system accounts for 3.9% of complaints (52 reports, 34 of them with a mileage figure), and it fails late — a median of 54,000 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 24,971 and 73,000 miles.

The airbag system accounts for 3.0% of complaints (40 reports, 11 of them with a mileage figure), with a median of 37,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 700 and 67,000 miles.

The fuel system accounts for 2.0% of complaints (26 reports, 26 of them with a mileage figure), with a median of 37,500 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 27,000 and 60,452 miles.

Differences between model years

Within this generation, complaint volume is not constant across model years. The 2021 model year drew the most — 616 complaints — while 2025 drew the fewest at 67. The median year sits at 245.

That makes 2021 an outlier: roughly 2.5 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 21 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 (5), the transmission and driveline (3), the hydraulic brake circuit (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 1,319 complaints filed against this generation, 32 reported a crash; 10 reported a fire; 31 reported an injury. Crash-involved reports represent 2.4% 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 14,000 and 67,000 miles, with a median of 37,000. There is no single mileage threshold to watch, which means condition and maintenance records are more informative than the odometer.

On inspection, the engine and the transmission and driveline are where this generation's reports concentrate, so those are the areas worth a specific look. The engine in particular shows a median failure mileage of 40,000, 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.
