Precision Toyota

I believe Precision Toyota of Tucson's service department is operating deceptively. I took my car there for service because there was buildup on the inside of the forward facing safety camera. The camera operated normally, but I was concerned that it may cause a malfunction in the future. I tried to resolve the issue with the dealership directly and through the BBB to no avail. My problem is that they claimed that the vehicle operated normally when it let particulate into the camera enclosure even though it could cause a safety issue. A camera safety system should not allow window cleaner fumes to penetrate the enclosure. They claimed I needed to pay a camera recalibration fee since it was a non-warranty service. What if an owner is a smoker, vaper, or lives on a dirt road? Does Toyota expect them to have the dealer clean the assembly EVERY time there is a built up substance and pay the recalibration fee? Or did Toyota design the system to NOT allow particulate matter into the enclosure? I DO NOT believe the camera system was operating as intended by Toyota (i.e., it allowed an "outside substance" into the enclosure). Furthermore, a service manager promised to give me the needed information to file a claim with corporate Toyota myself. The information I was provided is FALSE. The customer service director later gave me a FALSE contact number (the director's name is Sunny Davis). The service department cornered me and gave me two very bad options 1) Pay for the camera recalibration myself and HOPE that Toyota will cover the repair under warranty through reimbursement (which the service department gave me false contact information), or 2) Leave my car at the dealership until Monday at the earliest and HOPE that the service department can get the repair approved by Toyota as a warranty repair (meanwhile, I would have needed alternate transportation, e.g., a rental car). Both of these options would cost me money for a repair that should have been covered by the warranty. My camera worked when I brought the car into the dealership. I was concerned about the buildup as I did not think the housing should allow a film to develop as it could cause a malfunction, but it WAS NOT causing any error messages at that time. Only after the service department took apart my camera did the eyesight camera "need" recalibration (I believe the technician recommended it, but I didn't see anywhere it was necessary). At this point, I don't even think the recalibration was required, only a way to upcharge me. The camera worked when I brought in the vehicle for service - I was concerned that it could develop into a problem later.  I have already contacted Toyota corporate and they informed me that the dealership is responsible for determining if a repair should be covered under warranty. They did not do their due diligence. They gave me multiple false numbers to contact Toyota corporate for support.
