The contact owns a 2018 Subaru Outback. The contact stated that when driving approximately 30- 40 MPH, veering off the highway, the vehicle suddenly lost power, but had immediately regained power. The failure had occurred 3 - 4 times total. The last time it occurred, the vehicle took a bit longer to regain power. After pulling into the desired parking lot, the contact checked the battery. When touching a wire connecting to the battery, it sparked and caught fire. The contact immediately grabbed some snow nearby and threw it onto the wire to put out the fire. There was no fire report filed. There were no injuries or medical attention needed. The contact had noticed that the instrument panel would flash with several warning lights; however, it would illuminate quickly and intermittently. …
Sunday,August 1, 2021, at 9:05am, I backed out of my garage and when I attempted to turn my car, the steering locked, the car was drifting backwards and I had no brakes.

MY 2018 Outback experienced a driver side smoking mirror a few days ago. While parked at the gas station, a large amount of smoke suddenly began emanating from the driver side mirror. As a result I no longer see my TPMS, the ability to lock/unlock the car with the remote, interior lights no longer work.
I experienced premature draining of my car battery. I purchased the car in March 2021. It had approximately 19K miles and was in excellent/showroom condition. This is my first car with GPS and other advanced driving assistance safety features and collision avoidance systems. I'm still trying to understand all of these but some seem to have a mind of their own. I discovered the car's battery dead on the morning of 11/14/21. There was no warning that there might be a low battery problem and the car worked fine the previous day. I researched on-line about why this would suddenly happen and came across the Class-Action Lawsuit filed in April 2020 regarding these problems with Subaru Outback and Ascend models. I will also be contacting the legal team involved with the lawsuit, McKenzie Lake Lawyers, to verify if I need to take any steps prior to having my car fixed. …
The battery loses its charge so that the car will not start if I don't drive the car at least once or twice a week. The battery and electric system of the car was checked July 11, 2022 at the Bay Ridge Subaru dealership in Brooklyn, NY and all systems were found to be normal and good, including the battery. The battery is only 1 year old and is under a 30 month warranty. The Subaru service technician said that the car needs to be run for 45 minutes twice a week or this problem will keep happening and will lead to the battery needing replacement much sooner than normal. He also suggested I buy a portable battery jumper or a stronger bigger battery for $500-$750. So he acknowledged that this model has issues with the battery draining. …
