First things first you should contact your dealer. They should be able to offer assistance on these items.

That said, since you have a custom dash the arrangement of the indicator lights is unknown. There is 1 red light for low brake fluid and 1 red light for an alternator that is not charging. When the car is running are you seeing about 14 Volts? Then it's not that light. Since you are describing the brakes as being poor I suspect it's the low fluid light. Check your brake fluid level and also go over all the lines and the hoses and calipers and look for a leak.

You can get a warranty replacement on your turn signal switch, this is a new setup last year and some of them are not as tight. The lights turning off though is most likely a bad headlight relay BUT it could be another sign that the red light on the dash is indicating the alternator is not charging ... though you never mentioned it not starting or jumping it etc.

The vibration tied to RPM and not vehicle speed I would suspect is a flywheel or clutch issue.

How many miles were on your new car when you bought it?
