Multiple incidents of car not starting or stalling in rain. 1. After a rainstorm while parked, noticed water on the driver side floor and dripping from the driver door side under dashboard, water coming from defective design of sunroof water drains/tubing which are clogged because the tube is too thin which traps common dirt and dust from rain and road water.

Car would not start for 2 days afterwards until all the water was dried from interior cabin. This problem repeated itself every time it rained - I had to tape the sunroof closed to prevent water ingress as a temporary measure and ultimately had the tubing replaced by the dealership at a cost of $1326.97 which was not covered by warranty. …
