Vehicle make loud roaring noise during hard rain, and lost power. The vehicle acted like it was hydroplaning, however, they roads were puddled enough to cause such an effect especially at 5,000 miles, brand new tires. The vehicle sounded like the transmission was grinding, and after punching the gas, had no response. I pulled over and restarted the car, it did not fix the problem. The problem went away as the rain subsided. I don't have the exact date of the incident.
