Reliability & federal safety record

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

In the 2014 Challenger, complaints totaled 146—below the 2013 peak of 179 but higher than the 2015 dip to 126—showing a mild decline relative to the preceding year but not a sharp improvement. Recall activity remained steady at five, matching the 2013 and 2015 levels, while investigations stayed at one, indicating no new regulatory scrutiny that year. The top complaint areas—Electrical System (32), Engine (13), Air Bags (11), and Steering (11)—highlight specific concerns, yet the overall complaint count is lower than the 2012 high of 253, placing 2014 toward the bottom of the 2008‑2013 escalation curve. Fire‑related complaints were five and crash complaints 16, both modest compared with earlier spikes. Given the moderate complaint trend and steady recall numbers, 2014 is a reasonable year to consider, though buyers should focus on electrical and engine maintenance.
