When it’s time to change the cabin air filter in your 5th Generation Honda Odyssey (years 2018-2024), the Maintenance Minder will alert you with a maintenance sub code of 2. In my case, I had a B12 show up on my instrument cluster, which means that I’m due for an oil change and inspection (B), along with an engine air filter (1) and cabin air filter replacement. For more detailed information on what the various codes mean and how to reset the Maintenance Minder System when you’ve completed your service, check out this post.

Probably the easiest job you can do on your 5th generation Honda Odyssey is changing out your engine air filter. To change out the air cleaner element, you’ll need access to the engine bay where you’ll undo a few clips on the air filter housing. I was able to replace my air cleaner element in less than 5 minutes, so it is definitely a job that you should do by yourself rather than paying someone to do it for you.

Changing the transmission fluid is a bit more involved than say, an oil change, however it is a very doable job for anyone with the right tools. Doing this job will require you to lift your vehicle, remove some splash guards underneath the vehicle, and perform a series of steps in order to properly complete the job.

If you’ve owned your 5th generation Honda Odyssey for at least a few years now, you’ve most likely had your battery die on you. Not only are the original car batteries on these vehicles notorious for completely losing charge only after 2-3 years of use, but they tend to get drained if you happen to leave your car on (car on, but not running) for a short length time. Car batteries generally range somewhere between 2-5 years, so it seems the OEM battery on the Honda Odyssey seems to die a bit sooner than the norm.

If you own a 5th generation (2018-2023) Honda Odyssey and you don’t own any CR2032 coin batteries, you should probably stock up as it will only be a matter of time before the batteries in your key fob remotes run out. At that point, you might be stranded if you’re trying to start your vehicle because your key fob’s immobilizer chip is not being detected by your vehicle.
