Starter Solenoid problems of the 2003 Chevrolet Malibu

VIN: 1g1ne52j73m672590 I received a recall notice involving "possible unintended key rotation" and on may 11, 2017 I took the vehicle to a chevy dealer in sanford, FL. Both of the keys were fitted with a "plug" and two rings were added,. On my way home from the dealership, on I-4 at almost 70 mph, I had to brake when debris began flying up ahead. The battery and oil lights came on and I felt the car lose power and the steering began to lock. The other cars braked & I coasted to the emergency lane. I put the car in park and started it up again. Approximately 4 miles later, as I exited the ramp in deltona, the car did exactly the same thing. I called the dealership from the side of the road and asked why the car had never done this until the recall for the key issue had been completed and I was told to come back and they would do a diagnostic. I drove to a local mechanic & based on the symptoms determined it was the iginition switch and they also purged the solenoid, costing $366. Today, may 23, 2017, I was traveling on I-4 at about 65mph when it became necessary to brake. The stretch of road is rough, and while braking I saw the two lights come on and felt the engine shut off. I was in the passing lane with easy access to the emergency lane, and once again the car started up and I continued on my way and back home. I drove in the right lane the remainder of the trip down and back so I could bail out if needed. On the day of the original repair, after the car shut down twice on the way home, I checked the government recall page to see if there were other recall issues and I learned that the fob is not recommended to be attached to the key. I removed the fob from the key and attached it to a lanyard, but apparently that does not help the problem. The dealership returned both "corrected" keys to me on the fob, with a second ring on each.
