In August 2009 my catalytic converter attached to the muffler went out. They put in the code that was given for that job. I have had nothing but problems , I was back in the shop every other week because my emergency light would keep coming on. I am 68 years old and for me this is a safety issue because I didn't recognize my car was having other problems. This electrical problem has not been addressed/corrected to this day. L would appreciate if you would contact Toyota and have them take care of this.
