Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
The 2019 Honda Ridgeline recorded 230 complaints, 12 recalls and 4 investigations, with 115 TSBs, figures that exceed the 157 complaints, 8 recalls and 5 investigations, 113 TSBs of 2018 and the 162 complaints, 9 recalls and 2 investigations, 76 TSBs of 2020. After a low‑complaint period ending in 2015, complaint and recall activity rose sharply in 2017 and remained elevated through 2019 before tapering in 2020 and later years. Thus 2019 sits near the peak of the recent upswing, with complaint volume close to the highest in the 2017‑2020 window and recall counts still above the post‑2020 decline. The vehicle’s top complaint categories were Fuel System, Gasoline (34), Power Train (26), Engine (23) and Fuel/Propulsion System (22), and it generated 8 crash‑related and 2 fire‑related complaints. Overall, the 2019 model shows a higher frequency of reported issues than its immediate predecessors but does not exhibit a pattern of severe safety defects, making it a reasonable, though not optimal, choice for a used purchase.
