NHTSA complaint #11015035, filed 2017-08, 146,156 miles“The light for my air bag has been staying on and my horn quit working for over a year now. I finally took it to the shop for them to look at it, they told me it was a clock switch (I believe I said that right) which is something in the steering connected to the airbag and horn. I am concerned that the airbag might activate while I am driving which would not be good. Maybe even not work if I get in a wreck.”
