Is the Honda Odyssey reliable over the long term?
Reliability is one of the Odyssey's central selling points. The 3.5L J35Y V6 is a proven unit shared across multiple Honda and Acura platforms and regularly clears 350,000 km with 8,000 km oil changes using a quality synthetic. The ten-speed automatic introduced in 2018 is more complex than the previous six-speed — confirm that ATF DW-1 fluid has been changed at 50,000 km intervals. The power sliding doors are the most mechanically vulnerable component: inspect both doors and their guide rails for smooth, rattle-free operation at purchase. A well-maintained 2018-2021 Odyssey with 80,000 km is a solid buy.
