I live in central west
I live in central west Florida and my 2017 Honda CR-V's oil, stinks like a gas can. So, Honda saying that the problem is only in the cold climates is not true.
Before you sign a class action suit make sure you know what you will get. Typically, the law firm get the lions share and the signee get a small sum. Honda would love to settle this through a class action lawsuit. It would not surprise me if Honda hasn't hired a law firm to do just that.
