Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2018 Odyssey.
The 2018 Honda Odyssey is a VAN that carries forward a proven minivan platform, employing a 5.7‑qt 0W‑20 API‑rated engine coupled with an Automatic (S10) transmission and delivering EPA‑rated 19/28/22 mpg. Its powerplant and drivetrain reflect the model’s blend of efficiency and durability. In the broader complaint record, the 2018 version logged 939 owner complaints, with engine problems topping the list and 16 recalls filed, placing it just beneath the peak complaint year of 2002 (972 complaints) yet far above the minimal 1‑complaint year of 1994. This placement shows a reliability profile that, while not without concerns, remains markedly better than the worst‑case years of the Odyssey’s three‑decade history.

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
The 2018 Honda Odyssey sits at the peak of the complaint and recall arc for this generation, with 939 complaints and 16 recalls—far higher than the 39 complaints and 2 recalls seen in 2017, yet comparable to the 887 complaints and 20 recalls of 2019. This sharp uptick marks a brief spike rather than a sustained trend, as the following years (2020–2024) see a steady decline to 74 complaints and 4 recalls. The top complaint areas in 2018—Engine (88), Electrical System (87), Power Train (81), and Forward Collision Avoidance/Lane Departure (65)—indicate that most issues are mechanical or safety‑related rather than catastrophic. With 13 crash complaints and 3 fire complaints, the safety record is still within the typical range for this model line. Given the high complaint and recall counts that year, a 2018 Odyssey may carry more risk than earlier or later models; a buyer should seek a vehicle with a clean recall history and consider a more recent year if possible.
