Toyota Corolla starting issue

I’ve been having an issue with my 2017 Toyota Corolla LE (85k miles) for about a year now. Whenever I go to start my car, especially when it has been parked outside in the heat (the issue has been an everyday issue lately in Florida summer), the car takes way too long to start, it will crank for several seconds, instead of taking a couple cranks like it normally should. I have never had it completely fail to start, but it does take way too long to actually turn over. I have no check engine light or codes, as I already had a scan tool ran on it. I’ve tried looking it up and it could be a fuel system issue, or some kind of sensor issue, I’ve already had multiple mobile mechanics try to take a look at it but I’ve got nowhere.
