Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2011 Ridgeline.
The 2011 Honda Ridgeline is a truck built on a unibody platform, powered by an engine requiring 4.5 quarts of 5W-20 API oil and paired with a 5-speed automatic transmission, delivering EPA-estimated fuel economy of 15/20/17 mpg (city/highway/combined). In the context of the Ridgeline's broader complaint history spanning 2003 to 2026, the 2011 model year represents a relatively stable point in the vehicle's reliability trajectory, with 39 total owner complaints recorded alongside 11 recalls—a complaint count that falls well below the model's peak of 333 complaints in 2017, though not as low as the record low of just 2 complaints logged in 2015. The 2011 Ridgeline's standing within this range, combined with its Air Bags-related issues accounting for the top complaint category, positions this model year as a middle-ground example within the vehicle's lifecycle rather than one of its problem-prone iterations.

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
The 2011 Ridgeline sits in the mature, low-complaint phase of the first generation (2006–2014), where annual complaints stabilized between 24 and 45 after a sharp drop from the 2006 peak of 240. Its 39 complaints, zero investigations, 11 recalls, and 60 TSBs align closely with the 2009–2010 figures and precede a slight uptick in TSBs through 2013. Air bag complaints dominate the 2011 profile at 27 of 39 entries, though the data does not specify a root cause; crash complaints total two with no fire reports. Compared to the second generation (2017 onward), where complaints routinely exceed 95 and investigations appear annually, the first generation's later years show markedly better federal metrics. Recalls remained steady at 7–12 per year across the first generation, so the 2011 count is unremarkable in that context. This is a good year to buy within the first generation, offering low complaint volume and no open investigations, though buyers should verify completion of the 11 recalls and note the air bag complaint concentration.
