Against its own model years

The model year carries far more information than the badge, so this is the comparison that matters. The bar is how many complaints each rate rests on.

When it breaks

73% of reported failures happened before 30,000 miles (median 14,000 miles, from 79 complaints that recorded one).

Failures cluster early, which is the signature of how the car was built rather than of wear. A low-mileage example has not yet passed the risk window.

By engine

The VIN an owner files names the engine, which places 181 of this year’s 183 complaints. Sales by engine are not published, so these are not rates and say nothing about which engine drew more complaints. What can be compared is what each engine’s owners reported.

Engines as NHTSA’s VIN decoder (vPIC) reads them from the first eleven characters of each VIN. “Turbo” is shown only where every VIN records one; the decoder leaves it blank on many turbo engines. 18 complaints are not in the table: no usable VIN, an engine vPIC could not decode, or an engine with fewer than 25 complaints.

What NHTSA did

No NHTSA investigation covers this model year.

That is not a clean bill of health, and not a criticism of the agency: investigations open for many reasons and complaint volume is only one of them.

Limits of this figure. It counts safety complaints filed with the federal government, which is a floor on failures and not a census: problems that only cost money are under-reported. Complaint rates also reflect how likely a brand’s owners are to file, which cannot be separated from how often the car fails. Sales are calendar-year and the denominator for this nameplate is checked by hand against its source table, not against an outside figure.
