2017 accord reliability

I'm looking to buy a 2017 accord sport with 55k miles on it. I test drove it the other day and it went fine. However, google showed me the 2017 accord has an overall 2.5/5 (JD Power evaluation) and a below average reliability. My concern is its reliability and I wondered what might be the causes of its low reliability score. I appreciate if you owners/insiders can tell me sth about it. Thanks in advance!
