While driving approximately 70 mph on the highway, my 2018 Honda CR-V suddenly lost engine power and rapidly decelerated. At the same time the check engine light began flashing and multiple warning lights illuminated on the dashboard, including the ABS warning light. I was unable to accelerate and the vehicle would not restart after the loss of power. I attempted to guide the vehicle toward the shoulder for safety, but the vehicle was rear-ended shortly after the power loss occurred. The vehicle has since been declared a total loss by my insurance company. Approximately two weeks prior to the incident I experienced intermittent engine sputtering while driving. No repairs had yet been performed at that time. After the accident I discovered that my vehicle VIN is associated with an open fuel pump motor safety recall (EXP2) that had not been remedied prior to the incident. The suspected component involved is the fuel/propulsion system related to the fuel pump recall, although this has not yet been confirmed by inspection. The vehicle is currently in the possession of my insurance carrier and may be available for inspection upon request depending on the insurance process. The vehicle has been inspected by insurance representatives following the accident. The sudden loss of power at highway speed created a significant safety risk because the vehicle could not maintain speed with surrounding traffic and could not be restarted.
