Had my oil changed and tires rotated Tuesday. Shortly thereafter, check engine light came on as well as VSC/Trac light. Ode day later, I was making a right-hand turn and my steering wheel began to lock up on me. I pulled over, turned the ignition off, waited a few seconds, and restarted. Seems to drive fine now but lights are still on and I'm concerned it could lock up again at any time.
