I've noticed that my 2015 SH-AWD MDX has a new lag when I press the starter button. Last time this happened the battery was bad. This battery in it is less than 3 months old. I've seen threads here where folks say that the alternator does not fully charge the battery but that sounds kinda like a wives' tale to me. That said, is there any evidence that 3rd gen alternators turn off early on charging a battery/ I am puzzled by this new 3 or 4 second delay when starting even though my foot is clearly on the brake pedal. The MDX has 33,000 miles on it.
