My adaptive cruise control AND airbags FAILED when traffic ahead of me suddenly stopped. (There was NO airbag deployment.) I crashed into the person in front of me who then hit the person in front of them. The vehicle is available for inspection. I told the dealership at my 10k scheduled maintenance it was not braking or recognizing vehicles in front until it was so late I had to manually brake. I had a bunch of stuff in the front seat to where the passenger airbag light was on. It also DID not deploy. If someone had been there without a seatbelt there would have been severe injuries. Also I already had a "fuel sensor" that was bad that caused my vehicle to quit upon certain accelerations. My vechicle "quit" suddenly on multiple occasions almost causing a crash on the freeway and several other times on the highway. The EPA light always appeared when this happened and once the engine block light also came on. I could have been killed. I told them at my 10k service and that is when they said it was a fuel sensor and they would call me when it was available to be replaced. It was NOT replaced at the time of the crash.
