At 3k on this car, we have started hearing a whining/whistling/screaming sound at 70 mph while driving. It did not do this until 3k rolled over on the odometer. I am hearing it around the dash or front of the car on the inside of it. Dealership says it’s just road noise. They sprayed some stuff on the door sills and ruined the a pillar triangles on the door from where they sprayed the stuff where the car detects another car on the sides.
Please tell me this isn’t normal.
What should we do?
