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 engine accounts for 39.3% of complaints (1,733 reports, 591 of them with a mileage figure), with a median of 66,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 27,000 and 103,000 miles.

A single system taking 39.3% 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 9.9% of complaints (437 reports, 136 of them with a mileage figure), with a median of 37,750 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 12,513 and 70,025 miles.

The electrical system accounts for 8.9% of complaints (394 reports, 163 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 14,000 and 86,118 miles.

The steering accounts for 6.7% of complaints (295 reports, 113 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 22,250 and 83,500 miles.

The transmission and driveline accounts for 6.7% of complaints (294 reports, 129 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 25,000 and 74,500 miles.

The fuel and propulsion system accounts for 4.1% of complaints (180 reports, 52 of them with a mileage figure), with a median of 50,500 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 15,000 and 89,000 miles.

Differences between model years

Within this generation, complaint volume is not constant across model years. The 2015 model year drew the most — 1,657 complaints — while 2019 drew the fewest at 209. The median year sits at 995.

The first year of the generation, 2015, sits above the median. That is a common pattern — early production of a redesigned vehicle tends to surface problems that later years do not repeat — and it is worth weighing when choosing between years.

Recalls and what they cover

NHTSA records 12 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 electrical system (3), the airbag system (3), latches and locks (1). 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 4,405 complaints filed against this generation, 181 reported a crash; 167 reported a fire; 146 reported an injury; 9 reported a fatality. Crash-involved reports represent 4.1% 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, the two-peak pattern is the useful part. The early cluster — 19% of failures below 12,000 miles — will already have happened on any example you are looking at today, and either been repaired under warranty or not. Ask what was done. The late cluster, 18% above 100,000 miles, is the one still ahead of you if the car has lower mileage than that.

On inspection, the engine 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 37,750, 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.
