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

Car does not respond when accelerating/attempting to accelerate. Takes 3-5 seconds to engage when press on gas from stopped/brake position, also very slow to accelerate when changing speeds. Took car in for service and was told not transmission, but still having issue. Dealer stated they couldn't reproduce issue when was in for service, but nearly immediately upon driving away, it had same issue. No warming lights, sounds or smells occur when this happens. Nearly got T-boned on road due to slowness to respond. Unknown component causing issue.

The air bags failed to deploy. The contact's wife was injured. A police report was filed and the vehicle was towed to a tow yard. The manufacturer was contacted and stated that "there are many types of collision that are not necessary for the deployment of the air bag". The manufacturer used "if the vehicle hits a parked vehicle it would not deploy" as an example. The failure mileage[ was 80,000.

The approximate failure mileage was 72,000.

While attempting to make a left turn the car stalled and lost all power. The car had to be restarted and was able to drive back home. Took the car to dealership who stated it was a battery issue and a plugged air filter. NO check of the transmission was completed. This is the CVT transmission. The battery is 6 months old and the battery was tested multiple times by other locations and tested good. This stalling making a turn seems to be an ongoing issue with Subaru and the CVT transmission.

Hill start assist system failure. Apply power, but the car would not go very far before the brakes were automatically applied. Pull out into traffic and the car would not go. Dangerous. Warning message that the system hill start assist should be inspected by a Subaru dealer. Drove on deserted city streets for two minutes and then everything was okay except the warning light stayed on until I got home and turned the car off. I have found out how to deactivate the hill start system and I will do that. I have not yet taken the car to the dealer.

While rotating tires two wheel studs sheared off. The lug nuts are always started by hand, tightened (and removed) without an impact tool, and torqued to spec. Took it to a shop for repair. While removing the wheels two more studs sheared off in the shop. Mechanic stated this is a very common problem with Subarus. Google searches verify this. A popular Subaru community website has a thread with 168 posts discussing this issue among 2014-2018 model year Foresters - https://www.subaruforester.org/threads/2014-problem-with-wheel-studs-merged-thread.769466/ - Judging from online content it seems that, at a minimum, hundreds of Subaru owners are experiencing this problem, perhaps thousands. NHTSA and Subaru should investigate this issue and make it right for the many, many owners experiencing the potentially very dangerous problem.
