NHTSA Complaint #11451884 — 2016 HYUNDAI VELOSTER

Cruising on freeway ~70 mph when car starts slowing due to lack of power- for unknown reason car went into "limp mode", with turbo boost pressure and power cut off, barely enough power to keep car at 60 mph in order to make it to freeway exit to pull off. This could have caused serious collision. Turned off car, let it sit 1 min, turned it back on, and problem seemed to go away. No Check Engine Light, no OBD2 codes. Limp mode sometimes occur during harsh shifts but releasing throttle and reengaging usually fixes it but this time needed to shut off the car. Has been reported to dealer but they can't reproduce consistently and no CEL/codes so they won't try to find a fix. But losing power for no apparent reason on freeway definitely dangerous situation.
