Mazda Recalls 12,300 CX-9 Cross Over SUVs

I had taken my car in to get my timing chain renewed on wednesday 27 of August and my wife had picked it up that friday the 29th. During this service they had dropped a retaining pin for the actuator into the oil pan and charged me an extra 190 dollars, they also had to move a fuel line out of the way that they had informed me was not installed using a mazda certified bracket. Than they added that it would cost me another 900 dollars to fix. I barely had enough money for the 1500 dollar repair that they had got me on. I asked will it be fine without the bracket and she said yes that the technician would be able to install it and assure its safety. We were supposed to go and enjoy the weekend with family, i was already in san jose and my wife was driving from Modesto to meet me. In the car was my wife who was driving, my 2 year old daughter, and her three sisters( 12,14, an 21). She had just called me letting me know she was about to leave the dealership, 15 minutes later she says she smells gas and that the car is slowing down so i tell her to immediately get off the freeway. I call back the dealership to ask why this may be happening and my wife calls so i place mazda on hold. My wife is crying out of control that the car is on fire, i had no idea what to do. I was so far away and could not help, thankfully there are kind people in this world that stopped her and helped her and my family out of the car and out of traffic. My daughter was devastated, all she said that night was car and fire over and over, my wife blamed herself for this but i know its not her fault. I recently met with guys from the dealership and they didnt seem very helpful even though they claimed to want to help. I uderstand the insurance will pay the car but when i asked about the 1500 i had spent he semed to lead me more into buying a car off tem and that they would have good deals. I have more information on how the fire actually started from my mechanic looking at the car. What do i do? Many friends and family are saying to sue, theyre reason is to not let mazda get away with what they have done and to prevent this from happening to someone else down the road. Please help i am stuck.Thank you for reading.
