Hello Everyone!
I have a 2014 GMC Acadia denali and I have heard this ticking noise louder at cold start and then continues as the car warms up but at a softer rate.
I know that the bulletin:#07-06-04-025A: Information on Clicking/Ticking Sound/Noise Heard During Cold Start, Sound/Noise Decreases But Continues as Engine Warms-Normal Operation of High Pressure Fuel Pump and Injectors - (Nov 26, 2008)
was posted for 2009 models but does anybody know if it applies to the 2014 GMC Acadia Denali as well?
