I took my car last year for the recalls that had for the air bags and the interlock lever of he ignition switch. After one day of work they said they fix all of them. But after some month I notice that the key it was no working properly on the switch and I see also they didn't replace the old switch,and because I don't have sufficient knowledge of this issue I believe just what they said. But my car is having problem with the key ignition, the switch it's not reading the key most of the times and it's not starting and sometimes it start by itself without the key just pressing the horn. The recall for the interlock lever of the ignition switch is NHTSA 12v-573 manufacturer recall number s73. ( Dec 2012).
: the contact stated the radio controls worked intermittently. While on vacation, the cruise control suddenly stopped working. The dealership determined this was a common problem with vehicles of the same year, make and model. The defective part also affected the proper operation of the horn assembly, the steering wheel, air bag sensor, cruise control and radio controls. The dealership replaced the cable and reel assembly. The repair only corrected the problems with the radio controls and the cruise control.
