I got the call that every parent dreads,” Mom my check engine light came on.” I didn’t need to worry though. My daughter had attended the Car Care Class night at Waterloo Auto the year before. She quickly informed me it was safe to drive home as the light was not blinking and it was probably just the oxygen sensor acting up in the humidity. She nailed it! Diagnosis was confirmed. I love that the Waterloo Auto Team had prepped this new driver for whatever came her way. We got this fixed and did some other routine maintenance and my happy teen is back in her car to sing some more carpool karaoke with friends. Keep up the good work!
