While braking and attempting a left turn at an intersection, my vehicle completely shut down with no braking or steering control. Fortunately there were no damages and the vehicle started up again and I was able to clear the intersection. I took the vehicle to an authorized dealer for repair. They indicated that this was a known issue and they were familiar with it. They installed a battery sensor and did brake work as they said there was air in the system. I paid for the repair and approximately a month later, while slowing down for a red signal, the same thing occurred, only this time my vehicle impacted another vehicle, causing damage to both vehicles. I had my vehicle towed to the shop that did the initial repair, but they said they could not find any codes that would indicate that their repairs were faulty.
