I don't know about Ford. But it's a problem. Some say their batteries will last 100K miles. It's going to the junkyard after that because no one is buying a truck with that many miles that they have to put in $20K or so for a battery.The fleet is still really new but how they handle old age will be interesting to watch. When my Silverado has 200,000 miles on it, it kept running just fine. When that F150 gets up there, wonder what the resale value will be when, to keep it running, the new owner has to spend 10’s of thousands of dollars on a replacement battery.
