Other Fuel System Pump problems of the 2015 Honda FIT

My car suddenly started to shimmer and have a fluctuation in power as I was driving on the interstate at 60 mph. I had to move over two lanes to park on the shoulder and turn off the engine. The following warning lights were malfunction; traction control; power steering and the tire pressure light was blinking nonstop (it was on solid prior to the incident). I was not safe on the shoulder with cars flying by on the interstate. I pressed the start button and after a slight hesitation, the car started. I was able to drive a half mile on the shoulder and get off the interstate so I was in a safer location. The car's power was inconsistent as I drove this half mile. All the warming lights remained on. I had the car towed to the Honda dealer's shop. The Honda shop was able to replicate the same problem and warning lights that I reported. They said the high pressure fuel pump had failed and replaced it. They did not provide any explanation what the part failed. The car only has 12,000 miles on it and has had all the scheduled service and recalls addressed, now that the high pressure fuel pump has been replaced the car runs normal again. Exactly two weeks before this incident, the same Honda dealer shop changed my oil & filter and performed the scheduled maintenance checks and they replaced the plug top ignition coil per a safety recall. I have wondered if there could be a relationship between the failure of the high pressure fuel pump and the dealer shop having replaced the plug top ignition coil. I have the Honda dealer paperwork supporting my reports. The car's shimmering and loss of power on the interstate put me in serious danger of a car accident.
