Three problems related to carrier/rack have been reported for the 2020 Honda Odyssey. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2020 Honda Odyssey based on all problems reported for the 2020 Odyssey.
While driving on interstates and local roads, the onboard "infotainment" system continually emits loud popping, crackling sound (sounds like things hitting windshield), resulting in distraction and confusion while driving. Various components of the infotainment system randomly go out, causing system reboots while driving and creating distraction. Navigation system is also sometimes affected, failing to provide turn guidance or give accurate location. Rear "cabin view" freezes intermittently, displaying only still image rather than view of rear seats. Fm radio randomly cuts out, displaying "no audio connection for fm".
I purchased an Odyssey and within less than 2 weeks, the infotainment system started displaying problems. The system gives a loud, crackling noise over the speakers. Sometimes the audio connection will cut out with varying error messages. Other times the entire screen will go black/turn off for several minutes, completing disabling the backup camera and other functions. When the audio goes out it will also hang up/disable any goes going over android auto or bluetooth. The audio display screen for android auto will sometimes freeze. I've already had my vehicle in the shop twice for this problem within a month and a week of owning the car and there's been no resolution yet. I've seen that there's a class action lawsuit for this exact problem in the 2018 and 2019 models, which apparently did not get rectified for 2020. The problem occurs randomly and sporadically, but does occur almost every single time I drive the car at some point or another. It's extremely distracting and not safe.
Crackling noise from front windshield or dash area most frequent when the vehicle is moving but can sometimes be heard after coming to a stop.
