Loose connection.... i'd start with the alternator to make sure all the wires are secure... then the main connection to the fuse box in the engine compartment near the battery

    yep.... often that noise is caused by the heat shields the mount over the exhaust pipes. the corrode and break away from the bolts that hold them and fall against the exhaust pipe and rattle...

Sounds like the connection behind the instrument cluster is loose, i had a customer with the same problem only on a 2012 camry and it turned out to be the connection on the cluster. I just adjusted the tension on the connection by bending the contact pins a little.

Brake light flickers while driving down the road.


Check the brake fluid. It may be just low enough to occasionally turn the light on as you hit bumps and it sloshes a little. Add a little brake fluid to the reservoir and check the brake pads all around.
