“As I was driving down the freeway, my Mercury Mariner Hybrid displayed a stop safely now sign on the control panel. Not even a minute later, the car began to shut down and I had to maneuver get off the freeway. When I parked the car, I sat for a moment and then the car started right up. I drove another few miles and it displayed the same message and then stopped. It started again and then did the same thing again.”
NHTSA complaint #10626123, filed 2014-08, 138,500 miles“A stop safely now warning message came on when I was driving on the freeway at 60 miles per hour. The car immediately lost power and became difficult to steer. I pulled over to the right shoulder as safely and quickly as possible. This has occurred multiple times.”
NHTSA complaint #10630673, filed 2014-09, 60,000 miles“We bought vehicle in jan, 2018 from a private party, as a work vehicle for my husband, who is a usps rural route carrier. Two weeks after purchase, the anti-lock brake light went on, and the car would not stop when it was supposed to, which was very dangerous in winter. We believe the prior owner knew about this. The light would just go on & off with no pattern. About 1 1/2 months later, he was driving on a 2 lane hgwy (55 MPH) delivering mail. He went to pull forward but the car made a brief noise and then everything just stopped working. …”

The vehicle then lost power steering, and power to the engine. I restarted the car and made it ~100ft and the same thing happened again. This also happened several times previously on the highway traveling ~65mph and with the same message stop safely now message appeared and immediately lost all power to steering and the engine. …”
NHTSA complaint #10664554, filed 2014-12, 92,600 miles“I was driving down the road going 55 MPH and all of a sudden my vehicle jerked. I saw a red exclamation point on dash and where the car mileage is located, it said stop safely now. So I pulled over and shut down the vehicle, restarted and it happened again one mile away. It continued doing this. It took over an hour to get 10 miles down the road to my destination. It has been doing this off and on for the past month. I finally took the vehicle to the dealership and they said it is the throttle body.”
