2009 Ford Fusion electrical system problems

I had a history of recurring problems with my 2009 fusion. The battery died over and over again, causing me to finally replace it. The car constantly threw errors regarding low tire pressure. But the largest problem happened when we were driving down a two-lane highway at roughly 55 MPH and the steering wheel suddenly became unresponsive and locked, causing us to hit first the concrete divider on one side of the highway and ricochet across and hit the metal safety rail on the other side.

Tl* the contact owns a 2009 ford fusion. The contact stated that the driver's side door locks failed to lock and unlock the vehicle. The driver's door handle failed as well. The contact was able to open the vehicle from the exterior but not the interior. The contact had not taken the vehicle to the dealer. The vehicle was not repaired. The approximate failure mileage was 170,000.
