Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
The first generation of the Honda Ridgeline experienced a significant spike in complaints, recalls, and TSBs between 2006 and 2008, peaking in 2006 with 240 complaints and 110 TSBs. The 2009 model year marks a sharp decline in this trend, recording only 35 complaints and 0 investigations, a substantial improvement over the 140 complaints reported in 2008. This stability persists through 2014, contrasting sharply with the resurgence of complaints seen in the 2017 model year. For 2009, the primary area of concern was air bags with 21 complaints, though the data does not specify the root cause of these reports. While recalls remained consistent with neighboring years at 9, TSBs remained stable at 54. Given the significant drop in complaints relative to the mid-generation peak, 2009 is a good year to buy.
All 35 complaints on record, top 8 components.
