In owners' own words
I was at a red light and my car just cut off without warning. I put the car in park and started it back up.
Car gives warning message to "Immediately shut off the car to prevent damage ".... This has happened numerous times and Hyundai doesn't seem to have a fix, and doesn't think its a safety issue.
I bought this vehicle from a used car lot. I keep all maintenance up on this vehicle since I work as a lube maintenance technician.

Recalls for the 2017 Hyundai Sonata: 3
The Smart Junction Box (SJB) software logic may not properly interpret the signals received from the multifunction switch, which could cause the turn signal to activate in the opposite direction of what the driver intended. A turn signal that activates in the opposite direction of what was intended by the driver increases the risk of a crash.
The trunk latch may become damaged, preventing the opening of the trunk from the inside. A person inside the trunk compartment may become trapped, increasing their risk of injury.
In these vehicles, the end seal for the driver's frontal air bag inflator may not have been properly installed, possibly resulting in reduced inflation of the frontal air bag in the event of a crash. In the event of a crash, an air bag that does not inflate fully increases the risk of injury.
