Battery Dead problems of the 2015 Buick Encore

The contact owns a 2015 Buick Encore. While driving 45 mph, the steering wheel seized and the power steering warning indicator illuminated. The vehicle was towed to carl black Chevrolet Buick GMC (1110 roberts blvd, kennesaw, GA 30144 (770) 424-2200), but the failure could not be duplicated due to a dead battery. While the vehicle was being towed, the keys were left in the ignition and caused the battery to die. The dealer stated that the vehicle could have automatically reset itself as a result of the dead battery that needed to be recharged. The vehicle was not repaired. The manufacturer was notified of the failure and confirmed that the VIN was not included in NHTSA campaign number: 15v146000 (steering). The failure mileage was approximately 24,000.

While braking to stop for a traffic light on a busy 45 mph speed limit road, the engine stopped running. I shifted into park to restart it. Entire electrical system was dead except power seats and door locks. Engine would not start and no other electrical related equipment worked including engine, gear shift, instrument panel, radio, lights,turn signals, and emergency lights. Two safety issues because the car could have been rear ended: 1). Could not shift out of park to push car off the road. None of the 4 ladies in the car could get it out of park. Fortunately, when my husband arrived he could not get it out of park either. Two macho police officers gave it a try, but failed also. After some effort, the tow truck driver was able to put it into neutral by using the shift lock maual release. None of us ever heard of it 2). Emergency flasihing lights did not work GMC dealer told us a weld on the battery failed causing battery wire to short. I don't understand why some power worked, but there should be a backup source for emergency flashing lights.
