While driving my Honda Accord 2015 on interstate 75 in the left lane, the dashboard displayed a warning that there was a power system failure, the engine light came on. The vehicle immediately lost all power. The dashboard display was still lit and the radio continued to play. There was no resistance with the gas pedal and the car could only coast. I checked traffic and changed lanes to the far right emergency pull off. I turned off the car and then restarted it and the power system failure warning was gone but then a brake system warning came on. The car did travel foward with gas pedal and the brake seemed to work so I stayed in emergency lane and proceeded to closet exit off I75. I went to auto zone but they could not assist me. When the car was restarted all the warnings were clear. I took it the a Honda dealer and ask for a diagnostic. Honda service person said that if I was driving with both feet (one on gas and one on brake) that loss of power. I was not driving with both feet, so I asked him to run a diagnostics so I felt safe enough to drive home. The diagnostics revealed that the computer needed an update that was performed by service. I read the paperwork on the diagnositcs and there was a statement that described my incident completely with sudden loss of power. My car is not on a recall list. Honda seemed to know exactly what to fix, but I was never notified that my car needed an update resulting in power system failure. Why was this information not communicated to the owners of these cars? for a brand new car to be able to display all kinds of information (ie, oil life, range of miles, time for service) why can not the car display that its computer needs an update and to take in for service? there was no injury thankfully, but easily this could have happen, I was just lucky that I was able to coast over to the emergency lane and was not going uphill.

This is the second time that my car has had problems at 60 to 70 mph. It happens when coasting not braking. The high temperature warning for the brakes comes on and the engine shuts down. The car will coast and brake but there is no power. It takes 5 minutes before you can turn the car off and reset. Otherwise the car is locked out and will not function. Today I was on I75 going 70 mph with trucks all around. This is a safety issue. My local dealer has been responsive but the first time they ran the codes etc the national Honda folks had never heard of this. This is the second time with the same issue. First was at about 2500 miles.
