hi everyone I have a STR everytime I drive it the seatbelt sign flashes on the dash every 30sec 5 times each anybody have any ideas on whats going on? And my car shakes sometimes at 40mph then at 90mph is it bc of my winter wheel and tire I got 18s on dunlup spwintersport 245/40/18 or I need a alightment? Lastly where can I find brake rotors or pads at the best price and how can I tell if its the pad or rotors are worn thanks alot for any answer!.

 

As far as the seatbelt goes, are you wearing it?
If you are, then I would replace the seat belt buckle.
As for the shaking, is it shaking in the steering wheel? In the seat?

 

I put my seatbelt on like i do on my z4 its just that on the jaguar it keep telling me my seatbelt isnt on and keep beeping car is shaking from the steering wheel and shakes when i brake thanks

 

If it is shaking when you brake you probably have warped front rotors.
as for the seat belt I told you what to replace to fix.

 

Thanks a bunch btw how much do they charge for a seat belt bucket?

 

I don't know if your car has a seat belt bucket mate. j/k
It is the seat belt buckle, you need to give the dealer the VIN so they can match the color, it has pyrotechnics in it so do not use impact tools when you install it. Also, after you get the seat in the right position and unbolt it, make sure you disconnect the battery and wait 20 minutes before disconnecting connectors. The buckle is part of the airbag system.
As for cost....couldn't tell you. Sorry.

 

thanks for the tips
