What owners report
“I turned my car on and every light on the dashboard is practically on. It’s saying my (EPS) has failed and now it’s become hard to steer the vehicle. And none of my electrics as far as cruise control work and my speedometer isn’t working nor is it presenting me digital numbers on my dash.”

“The horn stopped working. Toyota verified it is the electrical behind the dashboard, which will cost $475.00 to repair. I was on the interstate highway 89 when the car I was passing started veering into my lane. I went to use my horn and it did not work! Very scary situation.”
