Warning Light On problems of the 2017 Subaru Impreza

After having car serviced, airbag warning light would not go off. I was told it would need to be "reset", then I was told there was a 90% chance there was a part over the rearview mirror where the front dome lights are that needed to be replaced. They ordered the part and when they were about to install it they said it wasn't that part but a wiring problem that is located over the passenger door inside the ceiling panels that were "chewed" by a rodent. However there were no signs of the rodent and they have no idea how the "rodent" might have entered the ceiling panel because of the tight space. I asked for a photograph. The wires are bare and it actually looks like a low grade fire caused from wires being exposed. I was told it was not under warranty and that it would cost over $600 dollars to repair. I was also asked at the time if I had any small rodent related pets, I do not. I called Subaru immediately because I wasn't buying the rodent story. The dealership has since called me back to tell me now they think a robotic arm might have accidentally damaged the wires in production but they are not sure. The car is not repaired as of yet, and I was told that the car is "safe" to drive. They also broke a part above the passenger visor when checking all this out because the space was so tight , yet a rodent got in and out and only destroyed those wires? they reassured me that they ordered the part they broke and will fix that when it comes in. However, because of the "wire problem" and me not approving the $600 "rodent" repair, my dome lights over my rearview mirrors will not work anymore, however they were working before they checked everything out. I am waiting for Subaru to call me back.

Dashboard airbag warning light is on when outside temperatures are hot. Happens alls surfaces/movement: stationary, moving, city street, highway. Passenger seat empty, driver in car only. Subaru dealer blamed it on my seat covers, after pushing for more research dealership says there is a known problem with airbag sensor but only techs who call into their tech help line are made aware. The part to fix the airbag issue/light is not currently available, and no specific date the part will be available to fix. Dealership states the issue is the sensors located on the interior roof of my car next to interior lights. States the sensor wires aren't coated well enough from heat, causing the light to come on/not properly registering if there is or is not a person in the passenger seat. Airbag is off if it doesn't register a passenger. Happened three times in the past two weeks.
