2015 Hyundai Santa FeRecalls, problems, MPG & safety

“While driving home at approximately 60 mph in our 2015 Hyundai Santa Fe, the engine suddenly shut off without warning. We were able to carefully maneuver the vehicle to the side of the road, but the vehicle would not turn over or restart. We were traveling with our young children at the time, and this sudden engine failure created an extremely dangerous situation that could have resulted in a serious accident. The engine failure occurred while the vehicle was in motion, leaving us in a potentially life-threatening situation on a busy roadway.

The 12V battery and electrical system remained fully active throughout. The instrument cluster was operational and capable of displaying warnings before the failure. None were displayed.
