Car would not start this morning. It’s driven every day, so it had not been sitting. Last service was 3/23 (today is 6/2/23), and the battery passed dealership inspection with no issues. Roadside serviceman stated this was the fourth “relatively new” Subaru he’d had to jump this week. Jumping the battery fixed the issue (for now), but the Subaru dealership, themselves, advised submitting a claim for potential “parasitic battery drain.” However, the current class action suit only covers 2015-2020 Subarus, and mine is a 2021 Outback.

This vehicle has 3 major issues that the dealership has not been able to resolve and are as follows: 1) Battery---is not able to hold charge. In early 2022, dealership replaced a new battery, however, the problem still exists. Battery size does not have the charge capacity REQUIRED to start the vehicle even less than 1 week of parking during warm weather months. 2) Heating System---has a defect, specially on driver side of the system. With seat and steering heating on, the vents on driver side emit uncontrollable hot air that forces the driver to shut the driver side heating system. During winter this is unreasonable! Did inform the dealership of this issue and were unable to resolve the problem as I understand was inherent with the design. This problem is likely to cause fire if electrical wires are exposed to the heat. 3)Tires---are supposed to be inflated with nitrogen, and this innovation is to maintain the tire pressures for most weather conditions. However, all of my five tires are unable to maintain the pressures. Did bring it to the attention of dealership at each service. However the problem still persists. Possible problem can be any of the following individually or in combination: a) Seal between the tire and rim is inadequate. b) Slow leakage in tire valves or c) Tires are of poor quality permitting air to escape from the body of the tires.

When there is an alert for “low windshield” washer fluid. I receive multiple audible alerts from the car while driving. The alert will go away and then come back. I think the fluid level sloshes while driving, going above and then below the sensor repeatedly. The multiple alerts are distracting and cause alarm fatigue. I think one alert per driving session would suffice.

The front windshield spontaneously cracked sometime overnight, while my car was parked in my garage. I noticed it when I got into my car one morning, and a roughly 6 inch horizontal crack had appeared, originating from the driver's side edge about halfway up the glass. I immediately got out and inspected the crack to find a point of impact, but it was a perfectly smooth crack line w/ zero points of impact. I drove the short distance to my destination, and an hour or two later when I got back in the car, it had continued to grow to maybe double the previous size (now 15-20" wide). The crack was directly in my line of sight from my eyes to the road ahead. The next day, I took it to my Subaru dealer, where they took photos and said they'd contact Subaru corporate to determine if they'd pay for the replacement. I just got news today that they'll replace it, but I'm responsible for a hefty "deductible" to replace their faulty glass.

The front windshield has a rapidly growing crack that now spans almost half of the glass. Our car was parked in our garage overnight, like it always is, and one morning we got in to drive, and there was a 6-8 inch horizontal crack that started at the far edge of the driver's side, in the middle of the windshield (right in the line of sight between my eyes and the road). I immediately got out and inspected the crack to find absolutely zero point of impact. I took it to the Subaru dealer the next day, and by the time they looked at it, it had grown to at least 20+ inches across the glass. They contacted Subaru corporate, who just called me back today to tell me that I need to pay them a deductible to have the glass replaced.
