Dash gauages flat line with brake, esp, abs lights come on

What is your question?

Car runs fine but gauges flat line some times and Brake, esp, abs lights come on. Then they will start working again then stop.

What makes this problem better or worse?

Not really but if I drive over something bumpy they will start working again.

How long has your 2007 Suzuki Grand Vitara had this problem?

Few weeks
