Well, I finally took my wife's Sport to the dealer to fix the Blind Spot problem. They performed TSB 09-24-9. He said the TSB tells them to pop the mirrors off and put grease in the connections. He said they didn't reprogram it because the system didn't show any codes. Well about 5 miles from my house the stupid Blind Spot Unavailable came on again. Im so mad. Those who took their car in and the dealer fixed the problem, what exactly did they do or replace? Is their another TSB? Will disconnecting the battery reset the system? Any help will be awesome.
