Hello everyone, my 2012 V6 has developed a new rattle. It's sounds like plastic rattling and it's coming from the dashboard on the driver's side, like where the windshield meets the dashboard. I initially thought the glass itself might be rattling, but it's gotten worse over the last couple weeks and now sounds like plastic. It happens at 50+ mph, or at around 1500 RPM when the engine is droning at a constant frequency.
