What lights went out on your dash? Like as in check engine light or TPMS light? If you mean check engine light there's no point asking anyone what the problem is because all that means is you've thrown a code and it could be any one of a million codes. Go to your local auto parts store, get the code read, come back on here and paste that number into the search box you can see just above your thread. Then read through existing threads on whatever code you might have.

Have you taken it anywhere to see if there are any codes? I have never heard of anyone needing to change all 4 speed sensors. Maybe one from getting damaged but never all of them. Did someone tell you they needed to be replaced?

So what was the code that came up? Search the code number on this site to see what others have done to fix their problems. I would be willing to bet replacing the speed sensors is not the fix.
