2016 VOLVO XC90 Forward Collision Avoidance Warnings Problems

Same issue as complaint #11416043. Leak in sunroof has caused several electrical issues with the car. I had noticed occasional drips from the rear view mirror but had no idea that water was pooling under the spare tire in the trunk where several electrical components are located. When I originally brought it to the dealer (when I noticed the occasional drips) they said I needed to replace a major part of the sunroof which would have cost around $2,000.

I have attached the preliminary report but dealership saying they need to pull up carpets, seats and dash to get to a full diagnosis. Here's summary I put together(Volvo Corp won't really communicate w/consumer). I have photos if needed: I also spent time the last several days continuing to do my research....

THEN WE STARTED GETTING ERRORS WITH SUSPENSION AND MY WIFE GOT A WARNING SHE SHOULD STOP THE CAR. SHE GOT IT HOME AND WE FOUND THE WATER HAD NOW LEAKED INTO THE REAR RIGHT QUARTER PANEL WHERE AT LEAST 1 COMPUTER IS STORED. THAT AREA HAD AT LEAST 1' OF WATER IN IT. I HAD TO PULL A DRAIN PLUG TO DRAIN IT. THE DEALERSHIP CONFIRMED THE COMPUTER WAS FRIED ($2600) AND HAD PREVIOUSLY SAID OUR DRAINS WERE CLEAR AND THE FIX WAS A NEW REAR SEAL. WHILE THEIR ANOTHER PERSON HAD JUST GOTTON THAT SUNROOF $2K FIX ON THEIR CAR. THE COMPUTER HAS DISABLED THE BLIND SPOT LIGHTS ON THE SIDE MIRRORS, FRONT COLLISION WARNING AND ASSUME AUTO BRAKING, THE REAR CAMERA IS...
