Horn sounded squeaky, then inoperative. Airbag light went on. Cruise no longer worked. Toyota diagnosed the spiral cable a/k/a clock needed replacement. Other vehicles, including Toyotas, had recalls on this. It should not have malfunctioned at this age of the car, only 108,000 miles. Should have been a recall, paid by Toyota. It cost me nearly $500 to get it fixed. Maybe the cable was damaged when the steering lock bar was fixed, on a previous recall (years prior). ???.
Air bag light continuously illuminated on the dashboard. As a result, the air bags were inoperative, the dealer inspected the vehicle 13 times and could not duplicate or correct the problem. The dealer replaced all the wiring, however the problem continued.
