My local Subaru dealership / service provider has told me my car needs a new transmission at 66k miles, due to an issue within the CVT solenoid causing slipping and lag that will eventually lead to catastrophic failure of the transmission - per the Subaru of America service tree. This issue began on July 23, 2026, when a slew of warning lights illuminated on the dash and my car went into limp mode, not accelerating properly. It eventually began driving normally and all dash warning lights dissipated. Dealership couldn't see the car at that time, then I was out of town for about a week. Came back, experienced the same issues within 2 days of driving the car. I was able to get it into the dealership for service on 8/6 where it was diagnosed, according to the Subaru Service Tree, as needing a new transmission. Subaru technicians cleared the codes, and I took the car home on 8/7/26 with the warning from my dealership that it was only a matter of time before the transmission failed. The lights / limp mode driving came on again on 8/9 and I have not driven it since that date. I have opened a case with SoA and am waiting on a "resolution". I do not feel safe driving my vehicle so it has been sitting in the driveway since 8/9 while I wait on a resolution from Subaru of America.

After my husband replaced the 12V battery in my 2021 Subaru Ascent Touring ($90,000, fully paid off), Apple CarPlay stopped connecting via USB entirely. Android Auto and Bluetooth continued working fine on the same phone, cable, and port, proving the defect was isolated to Subaru's CarPlay system, not my device. I spent significant time and money troubleshooting this myself: multiple cables (including two labeled "Apple certified"), a full infotainment factory reset, and a software update attempt, none of which fixed it. The issue only resolved after I purchased yet another cable at my own expense, with zero meaningful help from Subaru. When I filed a formal complaint, I received a response with an appointment confirmation left entirely blank (no retailer, date, or time), which I was told was "intentional" so I could fill in my own details, shifting all scheduling and diagnostic responsibility back onto me. When I requested compensation for hours spent troubleshooting a defect that was never mine to fix, I was told plainly that no compensation exists. Shortly after, my key fob began requiring near-direct contact with the door and push-start button to register, despite a confirmed correct, brand-new battery, ruling out the simplest cause. This is a second unexplained electrical issue on the same vehicle in a short span. Subaru's support has been dismissive and apathetic throughout, repeatedly redirecting responsibility back to me as the consumer rather than taking ownership of manufacturer-level defects.

Every time I go out of park there is a massive clubking noise from under the car. It's actually a super common item with these cars I am seeing as well in other forums. I believe this could lead to sheared parking brakes in the future.

The lane assist failed by over correcting while I have my hands on the steering wheel. It over corrects to the center lane when you are driving with normal behavior. This can cause a collision if it were to over correct while a car was there, this is also easily reproducible in my car.

I am a CPST. I use the Joie Mint Latch with my own child. On multiple occasions I have found on multiple occasions that when securing the lower rigid latch it will flip to green (secure) when it is not actually latched. It is during install when "jiggling" it into position. I am concerned parents who arent as well educated on car seats may not double check the latch before traveling and their child may not be safe.

I bought a 2021 Ascent - Touring , lately there was an ever increasing amount of wind noise. It sounded like it was coming from the sunroof, but I couldn't see anything from the inside that looked out of place and there were no signs of water leaking. I finally looked up on the roof from the outside and the weather stripping along the back of the sunroof was coming out. The glue is thin, and didn't even stick to it anymore.. This is an ongoing issue. There are people people on the Subaru Ascent, Facebook Reddit forms that have said they are having the same issue..

Purchased 2021 Subaru Ascent Limited outright, drove it for few months, started having pain in my right thigh that resulted in cramping and severe discomfort which affected my ability to feel the break pressure. This nearly ended up causing a couple of near miss rear end collisions. The pain got so bad that it caused me to lay prone and apply muscle cream to the affected area then remain prone for like 15 minutes before being able to continue driving until the pain returns. I consulted my Doctor and went through all the hoops to get an MRI, steroids, pain meds, heating pads, etc, without results or elevation. Ive tried cushions, padding and every possible seat adjustment still without any relief. I am scheduled for surgical consultation over this matter with strong possibility of surgery. There are thousands of Subaru owners throughout the web suffering from this same issue which has been medically classified by physical therapy professionals as " Subaru Sciatica Syndrome". The poorly designed seat has hard bolsters that jam into my thigh causing the sciatic pressure that causes the abnormal break pressure sensation. Therefore meeting two requirements for investigation. Subaru USA is aware of this problem and has banned me from posting anything educational on all their websites informing owners to the solution and action available. I had the seats looked at by an experienced car upholstery shop and repairs were estimated, submitted to Subaru upon their request, only to be denied.
