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

By engine

3.0L 6-cyl 4.8/10

No clear difference from this generation's other engines. (278 powertrain complaints, about 144,000 built)

2.5L 4-cyl 4.3/10

No clear difference from this generation's other engines. (70 powertrain complaints, about 26,000 built)

2.3L 4-cyl 5.7/10

No clear difference from this generation's other engines. (31 powertrain complaints, about 20,000 built)

hybrid (engine not listed) 5.9/10

No clear difference from this generation's other engines. (19 powertrain complaints, about 12,000 built)

A complaint counts toward an engine only when its VIN names the engine. These are powertrain complaints only, so they are fewer than the engine-code counts further down, which take complaints of every kind. Each score is that engine on its own against similar vehicles, worked out the same way as the score above.

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.
