Vehicle stalled while driving — unsafe loss of power. While driving at normal speed, the vehicle suddenly shut off without warning and the electrical system malfunctioned. I had to pull over and restart car. This created a dangerous situation and could have caused a collision. Prior to this incidenct, the vehicle had intermittent electrical issues during startup (flickering electronics). This is the first time the car has experienced during driving, and is now at the Hyundai dealership. The car has been reported as unsafe to drive. This appears similar to other Hyundai stalling/power loss issues and may indicate a developing safety defect. Requesting investigation.

I was driving down the road and came to a stop at a stop light. After accelerating again my car lost the ability to increase speed above 20 miles/hour and would not shift gears. I was heading to the turn lane to get on the interstate and quickly had to change lanes to find an area to pull over as I could not reach highway speeds. I turned the car off. I turned the car back on and the problem resolved. This is the second time this has happened. I have seen this problem mentioned dozens of time on Reddit message boards including Hyundai buybacks on some of these vehicles. It doesn't sound like Hyundai has any idea what is causing this issue. This issue should be looked into further.
