Similar vehicles are others in the same class, compared at the same age and in the same years. The score counts complaints owners filed with NHTSA, per vehicle built, which is different from the share of vehicles that fail. How the score is worked out

On the record

No serious powertrain recall covering 5% or more of this generation and no escalated investigation in NHTSA's files. Warranty extensions and settlements have not been researched.

Complaints by Engine Code

Every complaint of any kind (brakes, airbags, electrical and the rest) whose VIN names the engine, across all model years. The score above counts only engine, transmission and drivetrain complaints, so its figures for the same engine are smaller. Fire, injury and death figures count complaints that report one.
