electric runs rough
Complaint 1
I have an '08 Tahoe with the latest dealer updates. Once every week or two, after a cold start, I put it in gear and it doesn't move. I give it more gas and it surges forward and jerks rough until it smooths out a couple of seconds later. It usually won't reoccur for a couple of weeks. Since this occurs in both forward and reverse, it must be related to the electric motor, there is not reverse gear. Anyone else have similar complaints?
Complaint 2
When driving at any speed, the electric motor will make a loud whine. The whine pitch is speed dependent and will continue until I come to a stop. It then will not reoccur for a couple of weeks. Any thoughts?
Unfortunately neither problem happens predictably, so reproducing it for the dealer has not happened yet.

Re: electric runs rough
I have had the exact problem after a cold start.
Just took it in for fluid service and asked about that issue. The dealer never heard of it.
They scanned for codes and found nothing. I told them I hope that isn't the beginning of a larger problem.
I normally just restart the engine and the problem goes away.

Just wanted to post because this exact thing has happened to me a couple of times the last few weeks. It is always after I first start it. Surges and jerks a little bit and I let off the gas too try and smooth it out. Only has lasted a couple of seconds so far.

I have had a similar experience with my 08 yukon. On mine it almost feels like a slipping transmission engine revs but no movement or lurching movement. It has only happened a few times but it sounds like I may need to pay closer attention....hummmm

yes,only when cold and you are trying to hurry up. just had my transmission fluid drained and filled for maintenance. checked fluid level, it is okay.
