Driving both highway and city streets. While driving to work my turn left signal began to flash faster indicating a burned out bulb when the right turn signal started flashing faster. After work I could not unlock my car and had to have security unlock my car only to find my battery was dead. Security then jumped started the car, I drove off to battle my thru rush hour with out turn signals. The next morning the car battery was dead again, after getting it started I noticed the right front turn signal bulb stayed on even when the car was turned off,until battery was drained. I took it to my mechanic he said the Smart box would need to be replaced and programed, and cost about $850! I went to pickup the vehicle had trouble unlocking the door again this time the battery was dead again and needed to be replaced.
