It just depends,sometimes my both turn signals skip the middle bulb and blink just two per side,and the indicator on the dash blinks two fast blinks and a pause?
Any ideas?
After restarting it may go to normal.

 

i think there were complaints about wires in the trunk getting pinched (?)
try searching google

 

Check Battery Voltage. These tail lights can do crazy things if the battery gets a little weak even if it still starts and functions OK.

 

 

Just had this happen to me today. Was working fine and then all of a sudden the fast click inside, and no middle bar on the driver side. I banged on it a couple times, turned off the car to go to an appointment, and when I get back and started it up, everything was fine. First time this has happened to me. I have just under 57K miles.
