NHTSA Complaint #11472923 — 2015 SUBARU FORESTER

Sudden, without any warning, complete engine failure. Luckily I was in the right hand lane while ascending a major mountain pass. We were in the midst of a "atmospheric river" with rain coming from all directions when the engine just stopped. I muscled the car onto a very narrow shoulder and called for help, I knew we were in a very dangerous situation as this was the Saturday after Thanksgiving 2021, and the highway was full of cars and semi trucks whizzing past our Forester, we stayed put in the car. The State Patrol eventually appeared behind my Subaru, we conversed, and the officer used his front push bumpers to move my car up the remaining 2.5 miles up the the pass summit and onto a parking lot away from the freeway. Eventually AAA tow truck driver arrived, loaded our Subaru onto the platform carrier, with my wife and me in the cab, he drove 157 miles to our dealership parking lot. When we arrived, he again checked the battery, it was dead. He then proceeded to use an external storage to charge up our battery, and after a short time he successfully started our Subaru. I chose to leave the car at the dealership lot so they could check the systems the next morning. They could find no problem whatsoever with the engine, drive train, fuel system, or electrical system. The told us to report any problem to them, but stated our Forrester was safe to drive. The next day our trusted mechanic confirmed they could find no problem in our car. We have been driving our Forester per normal since this incident happened, the problem has not repeated. In summary no warning lights appeared on our dashboard before the incident; we used our lights to warn other drivers while we waited for help and eventually all lights went off; the problem has not been reproduced by dealer, mechanic, or us. What I believed occurred is: Driving through the "atmospheric river" the volume and intensity of the rain caused an electrical short, that was removed during the tow
