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 3500 sits in a brief plateau within an otherwise volatile federal record for this generation. After 2014's peak of 202 complaints and 17 recalls, 2015 and 2016 stabilize at roughly 133-136 complaints and 16 recalls each, with 2016 specifically logging 3 investigations and 489 TSBs compared with 2015's 4 investigations and 522 TSBs. The record then deteriorates sharply: complaints climb to 302 in 2017 and 777 in 2018, while recalls drift down to 13 and 11. Within 2016 itself, the leading owner-reported complaint areas are steering (22), wheels (18), unknown/other (10), and engine (8), plus 12 crash-related and 5 fire-related complaints. Because 2016 holds steady near 2015 levels and immediately precedes the steep 2017-2018 complaint surge, it sits at the calmer end of the generation's arc. The data does not specify root causes, but the year-to-year pattern suggests 2016 is a comparatively reasonable used-truck buy among these model years, provided recall completion is verified and steering and wheel systems are inspected.
