Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

The supplied year-by-year federal record contains no entry for 2015—or for any model years between 2009 and 2021—so the target vehicle cannot be plotted against its immediate predecessors or successors within a generational complaint-and-recall arc. Isolated target-year data show Service Brakes as the dominant category with 118 complaints, substantially exceeding Unknown or Other (34), Power Train (32), and Structure (24), alongside 21 crash-related and 8 fire complaints. Because the longitudinal record skips the surrounding years entirely, the data does not specify whether 2015 represents a peak, valley, or midpoint of reliability for this generation. Given that the highest-volume complaint area is nearly triple the next highest and the surrounding yearly context is absent, buyers should treat this year cautiously and prioritize a pre-purchase inspection focused on brake system condition and documented maintenance history.
