I took it back to the dealer and they adjusted the motor mounts but there's no change in the condition. They measured the vibration with a picoscope and said the vibration is within specificaions. I've test driven other Yukon's and they do not idle like this one. I Think I'm going to trade her but I'm not willing to take another chance on a GM product and going to go for a LX 570 since our Toyota's have been flawless. Really too bad for GM to loose me this way since I've been a longtime loyal customer having purchased 5 GM vehicles totaling almost 300k over the last 15 years.

Been on the road trying different fuels and no difference in the rough idle condition. If anything it's gotten worse. Now have 3500 miles on the odomotor. I have a video that shows the vibration. How do I upload it?

I've been running Kwik Stop 91 Octane ethanol free Top Tier fuel exclusively from a high volume truck stop. All of their 91 octane fuel is ethanol free and the move a lot of it so there should be no stagnation issues. I'm going on a 2400 mile road trip starting next week so I should get a chance to try a variety of fuel and see if it makes any difference.

I took it the dealer and they say no trouble codes detected and the vehicle is operating normally. They will not do anything fix the issue leaving me with no other options to get this problem addressed under warranty. Since the vehicle is exhibiting the exact same condition as the PI states there's probably higher than a 50% chance that it applies. I guess it's a matter of prospective as to whether they are honoring their warranty or not since all they have to do its deny there is a problem and your screwed.

I took my 2016 Yukon Denali with only 1500 miles on it into West Metro GMC due to rough idle concerns and even provided the TSB for the condition (PIP#5211) and was told that the bulletin didn’t apply to 2016’s and my vehicle already had the shims described in the bulletin already installed at the factory. I find this answer highly suspect and think it’s more likely that the bulletin hasn’t been updated to include 2016 models. The dealer also said that the rough idle is normal with direct injection engines and the vehicle is operating as designed. Ironically my previous Duramax was direct injection and so was the loaner car they gave me for the service appointment both of which ran smooth as glass. There’s no way a 81,000 vehicle should be running like this and if GM wants to be in the 81,000.00 SUV business they need step up their game. I am willing to pay for this repair myself as GM won’t honor their warranty. Does anybody see an issue with voiding my warranty by taking it into a non-gm shop to get the TSB performed?
