While attempting to accelerate on major highways (55-75 mph), suddenly orange "EPC" light along with orange triangle with ! appears on dashboard. Vehicle immediately begins losing speed, unable to keep up with traffic speed - capped at around 39 mph. Notification on touchscreen display, select "Vehicle Status", "1 message" next to the another identical orange triangle with !. Touched the messages to find orange ! and meter symbol, left of "Engine speed maximum 3000 rpm." Immediately drive to dealership, when I turned off the engine and parked the car to talk to a service center representative, it wiped the error from the vehicle completely. No EPC light, no message, and no data storage for the error that occurred. The dealership told me they were unable to re-create the issue, and sent me on my way. A few months later, the same issue had repeated 3-4 times, I took it to the same dealership, still unable to recreate issue. Now 2 full years have passed, warranty is expired, I bring it in having had the issue dozens of times (and documented with timestamped images), and the same dealership is claiming that the issue is the engine harness. This is extremely unsafe for other drivers, passengers, myself and my passengers. I have been fortunate enough to not have had any vehicles too close behind me when this failure occurs.
