SUDDEN AACCELERATION: Cold started the car in garage, all OK. Then backed out and into turn around where I placed foot on the brake. At that moment suddenly accelerated and engine revved to 2000rpm (sounded like). I had to push down very hard on the brake pedal (where my foot already was) to stop the car before crashing into a tree. Foot was clearly on brake pedal at incident (that was the only way I could stop the car). It was not on or close to accelerator pedal and no floor mat or other objects was on or near the accelerator pedal. Very concerned about safe vehicle with this sudden acceleration. Appointment with Subaru dealer made for full diagnostic check. Dealer is White Bear Subaru, [XXX] . INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Today while waiting at a stop light the auto start stop engaged. When the light went green I put my foot on the gas and the vehicle stalled. The car was on but not running, several alarms were on the dashboard. I had to put the car in park, turn it off and then restart the car. This is a repeated issue and has been going on at least once a month since we purchased the car in 2021. We've brought it to the dealer and they said there was nothing wrong because there was no OBD code. I have checked myself and I have not found any code. This is extremely unsafe

2021 Subaru Outback Limited | ~13000 miles | Component: Battery | Car suddenly stopped and ALL warning lights started flashing at a busy traffic signal, while I was waiting to take a left turn (lucky to have escaped safely from that situation). I had to turn the car off and restart it. 2 days later, the car would not start at all. Tried jumping it multiple time in vain. Had to tow the car to the nearest Subaru service center. Technician ran a diagnostic and concluded that the battery was not holding any charge at all and it was deemed faulty. Reading many posts on reddit and other forums of many Subaru owners facing the same issue from older (2015) to newer models. Many of them also complained of Parasitic drain on the battery due to faulty DCM on Starlink. Note: there was no warning lights/messages or any other symptom before this. This was a Subaru certified pre-owned car that went through a 152 point inspection in 2023.

On[XXX] while accelerating to travel speed (45 mph) on a rural Maine highway, the little used glass moon roof of our 2021 Subaru Outback Touring with 24,100 miles on the odometer exploded with a huge, shocking BANG!. Weather was clear and bright, wind ~5 mph, temperature about 68ºF, no traffic. We never saw or heard anything strike the car, either from the road or falling down from the trees at or prior to this incident. We had the interior shade closed so no glass fell into passenger compartment thankfully. Upon inspection at the road side and discovery of the problem, the glass panel had a large hole in the middle and the edges of the remaining glass looked like it had been blown upward.

Windshield breaks way too easy. Rock chips happen easily, then they spread across the whole windshield. I am on my 2nd one and this one needs to be replaced too.

The windshield is very light and delicate. I have had two cracked windshields in less that two years, Also, the glass is so soft that it gets tons of micro-pits from sand. At night they each disperse lights and make it difficult to see.
