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 2016 Ram 2500 sits amid a decade of fluctuating complaint and recall activity. Compared to 2015, complaints rose from 211 to 254 while recalls fell slightly from 15 to 14, and investigations stayed steady at three. In the broader arc, 2016’s 254 complaints are lower than the sharp spike of 2018 (2,493) but higher than the post‑2018 dip (189 in 2019). Recall activity peaked in 2013 and 2014 at 16 each; 2016’s 14 recalls place it near the mid‑range of the generation, suggesting no dramatic escalation. The top complaint domains—Power Train (36), Steering (32), Engine (19), and Service Brakes (18)—highlight typical heavy‑truck concerns, while the modest 14 crash complaints and 3 fire complaints indicate no extraordinary safety red flags. Overall, the 2016 model offers a relatively stable record, making it a reasonably solid choice for a used purchase, provided a thorough pre‑purchase inspection confirms the reported areas.
