DenaliLama

Picked my truck up...operating as intended, tech says no unusual sounds....

Add me to the list. 2014 with 6.2L that has had the noise since near new and now has 24,000 miles. Mentioned the noise at first oil change and was told dealer could not replicate. I have it in for service today and am having them look at the problem again. My noise is under light load at 1,000 - 1,500 RPM with the engine lugging a bit - as soon as the engine downshifts, the leaky manifold ticking goes away. Agree the noise is likely not causing harm, but is annoying as hell!

Just installed today using the BCM connection. I could not get a good connection stuffing wires into the back of the factory plug so I ended up using the scotchloks. Thanks for posting and saving time id'ing the wires. My lock did not come with a new c-clip...I will call to see if it was a mistake, or if they have changed the kit.

Just picked up '14 Denali with 8/14 build date and no vibration/shake after first 150 miles of driving. Want to thank you all for speeds/rpm to look for while driving. Hopefully mine stays that way and those with problems find a solution or other positive outcome.
