NHTSA Complaint #11518157 — 2018 AUDI Q5

My 2018 Audi Q5 has a water intrusion issue with control module damage. The vehicle reduce speed to 15 mph on the highway, when parked the lights would not shut off. The vehicle would then not turn on. Thirty minutes later the vehicle started. I received a front passenger seatbelt malfunction and several controls went out. The passenger seatbelt would not recognize there was a passenger buckled in the seat. The lights stayed on. The windshield wipers started on their own. The car wouldn’t recognize the key fob. Later the turn signal malfunctioned, along with the front lights staying on but the rear light and license plate light would not come on. At the dealership they found water in the comfort module housing, left rear quarter panel/wheelbase and said it was probably caused by the pressure vent seal allowing water to enter damaging the comfort module and 56 wires. They stated the vehicle was unsafe and inoperable. They also were not able to roll the windows back up or lock and secure my vehicle. The issues with the vehicle speed occurred 5 weeks ago. The dealership changed the thermostat but the speed reduction happened again afterwards once but when it was turned off and turned back on the speed went back to normal. Then today the vehicle just went crazy with things turning on and other controls not working, like the taillights. Multiple times I have told the dealership of the seatbelt malfunction. They said it was probably the seat detecting something on the seat, like a bag but couldn’t account for the malfunction when the seat was occupied. The vehicle is now at the dealership with plastic taped around the opened windows and unsecured since the locking controls will not work. They suggested I file a claim with my insurance for the repair. This screams defect to me!
