While driving the vehicle the digital dashboard for the RPM's and Speedometer, infotainment center, accent lighting and all exterior lighting including tail lamps, head lights, turn signals and marker lights all powered off for approximately 2-3 seconds. During this time, the engine continued to run as if nothing had occurred. After the 2-3 seconds all affected systems that shut down turned back on and continued as if nothing had occurred. Even Apple carplay had no signal reconnection time, almost like it was never disconnected in the first place. This issue appears to just shut down all outward lighting/indicator lamps and then power back up. This issue has repeated itself on 5 separate occasions over the course of the last 3 days. Took it to a dealer on the 4th day (today, March 6th), and they could not get the issue to replicate despite driving for 30 miles and having it for 3 or so hours under their care. No codes were logged, no indicator lamps showed an issue and no erratic driving or lasting effects of the power blip. Outside of the dealership this issue has not been inspected further. A contact was made with Hyundai USA in attempt to address this safety issue. No reply has been received since submitting yesterday afternoon. This issue has happened during the day as well but given the lighting conditions is not as dangerous as losing all head lamps or tail lamps at night where the driver or other drivers may be affected as they travel about the roadways in the case of merging on and off of a highway or being able to see any animals that run into the roadway.
