    - Old town, ME

    Purchased in August 2024, had to get a new battery 2 days after purchase & then went to the dealership January 2025 because my battery kept dying & I was stranded at the airport late night. They acknowledged is has a parasitic draw but did not notate the source. They claimed I needed a new battery when my previous Subaru branded battery was only 5 months old. The new battery was almost $600 which is double/ triple a store branded equivalent. I purchased yet another battery but non-Subaru branded since theirs did not last even 6 months. Still have been experiencing the same issue. I pulled the dcm fuse and let my car sit for several days as a test. The battery did not die with the dcm fuse removed. The front speakers and Bluetooth are linked to the dcm fuse so they do not work if it is unplugged.

    Subaru Starlink alerts keep disrupting my navigation so it’s making driving unsafe bc it pops up and interrupts Waze Navigation and has to be addressed to get back to my map. It happens incessantly and persistently even though I’ve turned off app Starlink access and alerts. It is a distraction to my focus while driving and i fear it will cause me to get into an accident. Why hasn’t Subaru fixed this known issue?

    The car in front of me was about a two car's lengths away. It was very cold and that car's exhaust plume was larger than normal. The exhaust plume was highlighted by sunlight, and I believe my car thought it was an object. The auto braking system alerted and immediately slammed on the brakes in the middle of heavy traffic. There was no time for me to respond. Thankfully no one hit me. If I'd been on the highway it could have been catastrophic. The problem has not been reproduced or inspected.

    The vehicle shuddered violently when turning the ignition, and then failed to start entirely. The mechanic found that the engine coil was severely damaged, no external influence, just that it had become worn out remarkably fast. The vehicle has less than 60,000 miles and just 5 years in service. The repair will end up costing about 1500 with tows included and the vehicle has not gone without maintenance or care.

    The backup camera on my Subaru Crosstrek started to a stop working a few weeks ago. It first started to intermittently transmit a video feed that was fuzzy and the colors were completely incorrect. That started to follow with the camera not working about half the time at all on my head unit. Now it's completely not showing up at all on my head unit when I go into reverse. I live near a school and when I back out, I'm concerned that I won't be able to see a child behind my car. Same for parking garages and parallel parking. The Subaru dealership is saying they have checked all the wiring and modules and have isolated it to the backup camera. There were no other messages besides the camera starting to malfunction.

    While driving 65mph on the freeway the front passenger window imploded into the car. This threatened the safety of both the driver and passenger as the glass flew at such high velocity it ended up in both occupants clothes, hair, and skin, the glass also was found as far as the trunk. This endangered the safety of others driving on the highway as the driver was shocked and caught off guard at the sudden implosion. The problem has been found in similar model subaru's including examples of moonroof and rear windshield implosions. The vehicle has been inspected by the local dealer yet they are claiming to have found no abnormalities in the window systems, but are unable to ensure that the glass was tempered properly. There were no symptoms of the problem prior to failure.

    On Friday evening, [XXX], while closing the rear driver-side window, I heard a loud mechanical snap, after which the window failed to operate. The window regulator has binding issues (as documented in Subaru TSB 07-189-21R). This mechanical binding disables the anti-entrapment (anti-pinch) safety feature. The sensor is bypassed by the binding/mechanical failure, the window will not reverse when it hits an obstruction. This creates a direct entrapment and crush risk for passengers, specifically young children. A Subaru Customer Advocacy Manager (Jennifer) admitted on a recorded line that “the part should not break” (Case #[XXX]). Despite this admission and the documented safety risk, Subaru of America refused to authorize a safety repair. The failure was inspected and confirmed by an authorized Subaru Service Center (Walser St Paul). No warning lights appeared prior to the failure as it is a pure mechanical defect. I have the recordings, but I’m not able to upload them at the moment. Please let me know if needed. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

    - Newbury, VT

    The contact owns a 2021 Subaru Crosstrek Hybrid. The contact stated that after moving the vehicle 10 feet from a pile of snow in cold weather, the vehicle restarted but failed to run and then shut off after 2 minutes. The contact changed the 12-Volt battery. Several unknown warning lights were illuminated, and the “Service 12-Volt Battery” message was displayed. The vehicle was towed to the local dealer, where it was diagnosed, and it was determined that the inverter connector was corroded. The wires underneath the vehicle had been damaged due to water, salt, and sand, causing the vehicle to become inoperable. The vehicle was not repaired. The vehicle was previously repaired under NHTSA Campaign Number: 23V0800000 (Electrical System). The vehicle was repaired, but the failure recurred. The manufacturer was contacted and offered partial claim assistance, but the owner declined. The failure mileage was approximately 125,000. The VIN was not available.
