GMC Yukon Denali Problem Report

GMC Yukon Denali "No start" due to anti-theft system failure

(8 reports)
The anti-theft system may fail causing a no start condition, the security light may illuminate. Our technicians tell us that the ignition switch may need to be replaced to correct this fault.
That can't fix it yet after 3 stations and a dealership tried. -
At times will not start no crank or nothing,but some days it would start like everything is normal. So when it didn't start i would jerk the key ignition back and forth until it started. -
