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…

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…

On two separate occasions, the vehicle suddenly lost what appeared to be power-steering assistance while the vehicle was in motion, causing the steering wheel to become extremely difficult to turn.

My 2021 Subaru Outback suffered a failure of the Oil Control Valve (OCV), a sealed Subaru component with no maintenance interval, no inspection procedure, and no preventative service. This failure allowed engine oil to migrate into multiple wiring harnesses and modules, causing extensive electrical contamination. This is not normal wear and tear. It is a latent defect in a Subaru component. Due to the failure of this sealed component the Subaru dealership and a second…

First battery drain in car. Bought a new battery and it drained again for the second time. Called Suburu to ask about a parasitic drain from the DCM and they said it was likely that and told me to call Suburu America. Did that but they wanted me to take it to a Suburu dealer to get the problem verified. I don’t have the $ to do that. I notice there is a class action in court right now for this exact problem.

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 -…
