Visibility/wiper
98 reports1 crash
“I was driving when I heard a loud explosion sound. I first thought a rock or gunshot hit my car and pulled over to examine my car. I checked all around the car and didn't notice any damage on the side of my car but then I noticed that my sunroof was shattered. The glass was pushed outward which meant that it was not hit by an object. Luckily, my interior cover to my sunroof was closed at the time so I was not harmed.”

“Vehicle's Auto Start-Stop system shut the engine off while stopped at a red light in [XXX], in rainy conditions in late XXX at approximately 29,000 miles. When the brake was released after the light turned green, the engine did not restart, leaving it stopped in the travel lane in live traffic. The driver had to use a portable jump starter to get it running again. This was not isolated — repeated failure-to-start incidents in prior weeks had already prompted carrying a portable jump starter in the vehicle. At the time we believed this was a failing 12V battery. The original battery was replaced XXX with a new aftermarket AGM battery. Despite that replacement, the vehicle has continued to have multiple complete battery drain if left parked for multiple days (but less than a week), indicating the restart failures were likely caused by an underlying parasitic electrical draw rather than a simple worn-out battery. Subaru's own Technical Service Bulletin 07-199-21R, "Measurement of Dark Current (Standby Current Draw)," describes this exact failure pattern (batteries/vehicles going dead over time due to standby current traced to the VDC module and/or Power Rear Gate…”
Forward collision avoidance

“I was already parked in a spot in a public parking lot. I tapped the accelerator pedal to move the car a few inches. The vehicle responded by violently accelerating, hitting a vehicle directly in front of me in another parking space. I applied my brake but the car would not stop. The force of the acceleration pushed the car out of the it's spot and it hit a curb and tree appox 30 ft away. In defensive move I turned my wheels to the right and continue to try and brake. This caused my car to hit the car on the right side of me. Property Damage occured. No injuries. Vehicle defect.”

“Good Day! I bought my 2021 Subaru Outback XT Onyx in Jan 2021. I had waiting 6 yrs for Subaru to use the Turbo Motor in the Outback again. I've had this car for 5 years with my warranty running out Jan 2026, but I only drive 5000-7000 miles per/yr. Current odometer is 29,901 miles. At my most recent oil change service at the Dealer, they showed me a video of my cars drivetrain from underneath. There were two bad seal leaks. One at the transmission pump housing and the other at the Upper Oil Pan. I had been there for an oil change a year earlier for the same service and there was no mention of these issues! After speaking with the service advisor, he said to call Subaru Customer Advocates. They listened to my situation and a few days later offered a $1400 credit for a $4000 job that involves the removal of my cars engine (upper oil pan) to replace it because it's bolted to the frame there. The other leak seal involves dropping the transmission. These are major repairs that following will dampen my ownership experience after decades of Subaru praise by Americans. I researched this issue online and found out there was a manufacturing defective regarding the…”

“We are VERY concerned about the failure of some very important safety features of our 2021 Subaru Outback Touring Edition. We were involved in a bad car accident caused by a person under the influence who was in handcuffs when we were taken away by ambulance. As you can see by the photos, there was MAJOR damage to the other car and significant damage to ours. What is most concerning is the fact that NONE of the airbags deployed and the safety and security plan also failed - it did not call 911. I had to find my phone on the floorboard and call 911 myself. I am not sure if the insurance company will call it a total loss but I really don't think I want the car back BECAUSE of the failures of these very important safety features. I truly feel like Subaru has some explaining to do on this.”
