On may 30, 2026, I was driving the freeway 2(glendale fwy) south, I was using the cruise control and driving 63 0r 68 miles. All of sudden, my car start to shaking violently, moving toward right lane, so I tried move my car back to my lane. My car was out of control and driving zig zag way then went up to hillside of the freeway and roll over end up crash on the concrete swale. I thought that was my last moment of my life. I could not move, severely injured and my car was totally damaged. The driver was driving who witnessed whole thing from behind my car, stopped and called 911. He was kindly came to me and gave me a drinking water. The mileage in my was about 68000 miles and I did maintenance as the manufacture recommended it.
Two incidents happened first battery died, we replaced the battery. Then battery died again, we replaced the alternator on June 5, 2025. Then on Saturday September 13, 2025; all system lights came on at once on the dashboard then the battery died again. Car locks up and is stalled out. Cannot restart car, has to be towed. We replaced the battery cable and cleaned the terminals. Three months later, December 1, 2025; the battery light came on then all system lights came on at once, the battery died again. This happened on interstate 95, it could easily have caused a crash. Car locks up again and is stalled out again. Cannot restart car again, has to be towed again. Something in the electrical is causing this, we do not know what.
Lately, airbag warning light comes on intermittently often. Sierra Subaru would not fix without charging me for inspection for $240 and then cost of rapair. Also cruise control is malfunctioning where it gets disengaged near the vehicle in front where I have to apply brake hard to avoid serious accident. Also the eyesight not working warning has started showing lately. My Forester 2017 at 44k miles showing airbag light at times along with cruise control disengaing near front car and eyesight not available mentioned above. Detail on airbag fix at sierra Subaru in monrovia, California. On August 12, 2025, I want to get this intermittent error fixed under warranty. On August 12, 2025 alexander in service told me that it will be $240 approximately of charge to inspect. Kindly let me know if the airbag warning light at such low milage not going to be covered for warranty. Please note that I bought the Forester at sierra Subaru monrovia CA and had every single service done there. Lately I have been charged in thousands of dollars at such low mileage to own the 2017 Subaru Forester.
