That’s not good! If you’d like to ask a question and get an answer, you need to supply information about your Bravada and a better explanation of your when and how long problem has been around.

Tire tread wear, wheel out of balance, driveshaft imbalance, and suspension system play is where I’d start looking with that problem.

Its telling you it has gone past its expiration date.
