Is this too many miles for a hybrid?

I have a 2008 honda civic hybrid, with 320k miles on it with the original engine, transmission, and battery, my friend told me most hybrid batteries don't even last 150k miles and that i should sell mine before something goes wrong, is he right?

I would suggest taking it in and getting everything checked on it by a professional. Just remember- the more miles you have on a car, the less it will end up selling for

That's an argument for never buying a car at all.

You might be better served by getting new friends.

Battery life for the HCH was a real grab bag. In the early years there was a serious problem with battery life and yours is in that category. By the 2009 model year the issue reached a head and Honda started using less aggressive hybrid programming to maximize battery life at the expense of fuel efficiency. A class action suit followed, and Honda paid a paltry $100 to original owners of HCHs within whatever the limits of the settlement were.

The source sums it up best: "Now that it's 2016, anyone who purchased or replaced a hybrid in 2008 or 2009 should begin planning for a replacement." With the vehicle being 10 years old (the 2018s are out) and with 320K miles that means replacing the vehicle rather than the battery pack. With that decision made, and considering it is worth a lot more to you as a (presently) running car than it would be to a buyer, I recommend you keep it and start saving for the next one. It has had a good run and it is not over yet.
