Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2023 Ridgeline.
Equipped with a nine-speed automatic transmission, the 2023 Honda Ridgeline achieves an EPA-rated 18 mpg city and 24 mpg highway for a combined 21 mpg, with its engine requiring 5.7 quarts of 0W-20 API oil for proper lubrication. The vehicle's reliability profile currently reflects 121 total owner complaints and five recalls, with exterior lighting standing out as the top complaint area. Within the model's broader complaint history spanning 2003 to 2026, this iteration sits well below the problematic 2017 peak of 333 complaints but far above the 2015 low of just two, meaning researchers should view the 2023 Ridgeline as a moderate year in the nameplate's lineage that carries distinct but not extreme reliability concerns.

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
The 2023 Ridgeline sits in the middle of the second generation’s complaint arc, which peaked at 333 in 2017 and has generally declined since. With 121 complaints, 5 recalls, and 64 TSBs, the 2023 model is slightly above the 2022 figures (111 complaints, 3 recalls) but well below the 2017–2019 highs. The top complaint area—Exterior Lighting (38 reports)—is a specific concern not seen as prominently in adjacent years, and the two crash and two fire complaints are notable, though the data does not specify root causes. Later model years (2024–2026) show even lower complaint and recall counts, but those figures may reflect shorter reporting periods. Overall, the 2023 is a relatively stable year within the generation’s downward trend, but the lighting complaints and moderate recall count mean it is not the most trouble-free choice; a 2024 or later model, if available, would likely offer fewer reported issues.
