2 Adaptive Cruise Control problem

Failure Date: 08/12/2025

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.
