According to
Ford's website the battery warranty on that car is eight years, 100,000 miles so there is a good chance it is still under warranty. I believe the bigger problem is that Ford only made these for a couple of years, and they stopped making the battery years ago. The article states that they can't find a battery for it, which is most likely why they are giving a ridiculous price. The dealer is trying to make them go away.
I am also shocked and appalled that an eight-year-old car had an issue that led to repairs that were worth more than the cost of the vehicle. It's a good thing that has never happened up until EVs came onto the scene. I am certain no one has ever had an 8-year-old Jaguar or BMW encounter anything close to this. The Ford Focus itself is known for its incredible reliability. It's not like there were
multiple class action lawsuits against Ford because they knowingly sold a vehicle with a known, unrepairable transmission issue.
It is also a good thing that a website that calls itself "business news" managed to find the one example out of the hundreds of thousands of EVs that actually had this problem and then have the courage to report it back to us. That is some hard-hitting reporting! If this were happening across an industry, a manufacturer or a model that would be Business news. If it happens to one car, that is an anecdote.
