I own a 2019 lexus es 350. At last servicing battery passed the test. Is it better to change battery at the dealership. I have read here that lot of owners had headaches after changing battery themselves. Mine is at 4.5 year mark. Is it better to change it now. I don't drive much these days. However, I am not having any problems that are battery related. Would like opinion of other es 350 owners.
