My speaker grill on the driver side was squeaking when driving over bumpy roads (the only kind in SLC). The service center supposedly put in some sound deadening material. It still squeaks when it is cold out, but it stops when it is warmer, or the sun has been shining in the car. The car is otherwise silent. Hopefully someone will post if they get a definitive fix for this seemingly common issue.Dude! My speaker grill has been rattling too. I hear a few squeaks in the back, but I think they may be my twin's car seats. My appointment is on the 24th of March. Originally 28th of February, then pushed to the 14th of March, and finally pushed again to the 24th of March. Assuming it doesn't get pushed back yet again, I will get some answers including why my car refuses to update to the latest firmware.
Here is an interested bit of info. I took my brother and his daughter along with us to the Houston Rodeo last night. They loved the car, but the only feedback that bugged me was how uncomfortable the seat belts were for the captain's chairs in the middle row. They said they were oddly positioned and dug into their neck. I can see that for his daughter as she's 5'5", but my brother is 5'11". So not sure what to think of it. That's something I hadn't tried myself as I'm the driver. But curious what others' feedback may be regarding those seatbelts.
