Sounds like the blinkers are blinking but they're not. Traction control and abs lights are on. (spent over $1200 on 3 visits to solve this one) Security light flashes and car won't start for 10 minutes. First 3 speeds on fan don't work. Rear speakers only work when it above 70 degrees. Other than that it's a wonderful car!

BLINKER PROBLEM IS THE MULTI FUNCTION SWITCH FAULTY.WHICH IS THE TURN SIGNAL SWITCH DIMMER SWITCH AND WIPER SWITCH AND ALSO HEAD LIGHT SWITCH.YOU HAVE REMOVE STEERING COLUMN COVER BEFORE YOU CAN REMOVE THE MULTI FUNCTION SWITCH.TURN OFF RADIO DISCONNECT NEGATIVE BATTERY WAIT 15 MINUTES SO THE AIR BAG IN STEERING WHEEL WILL DISCHARGE. SECURITY LIGHT PROBLEM IS IN THE CAR KEYS WORN WHERE THE BCM AND PCM CANT RECOGNIZE THEM OR THE IGNITION SWITCH AND BCM IS FAULTY.THIS IS A DEALERSHIP FIX THEY HAVE TO REPROGRAM THE KEYS OR IGNITION SWITCH AND THE BCM.ALSO THE ABS AND TRAC LIGHT ON.CHECK ABS FUSE OR RELAY IF BOTH GOOD.DEALERSHIP HAS TO FIX THEY HAVE SPECIAL SCANNER TO CHECK THE ABS AND TRAC SYSTEM. FOR SPEAKERS EITHER THEY HAVE POOR WIRES CONNECTION
