#295 of 300 Tahoe Hybrid Driveline noise by tahoedrvr Jun 01, 2009 (1:33 pm)
I'm checking to see if anyone else has this issue.   My '08 Tahoe Hybrid, w/14k miles, makes a noise that sounds like a cross between a suspension creak and a u-joint clank when it pulls away from a stop. Tech thought it was crossmember flex/pop. Now they say it is normal noise. I don't recall it on the demo I drove for a day. Everything like transmission and motor mounts, u-joints etc, has been checked, lubricated. I don't think they've sold a lot of these things, so I'm skeptical when I'm told its "normal" noise. Anyone out there have this same noise? Other than this issue, we're happy w/ the vehicle, our mileage is a consistent 22+ mixed city/commute, and high as 25+ on trip at highway speed (Yes I checked it several times). Big improvement from our '04 Suburban (which we kept). I got this at end of September '08, basically because it was the most steel I could put around my wife and kids per gallon of gasoline.
#296 of 300 2009 Yukon Hybrid 4X4 noises by lesgas1 Jul 28, 2009 (9:39 am)
I have a 2009 GMC Yukon Hybrid with 4300 miles on it. The vehicle recently started making a noise while accelerating and braking. The sound is strange it's a combination of a thump, thump, thump and a whirring. It really gets annoying and it can't be hidden by turning up the radio. Again this is a new sound, I know what the hybrid should sound like. The Dealer took a look and found nothing. Has anyone else experienced this noise? Thanks

Hi,   My Yukon Hybird seems to be hesitating much more than it should. It also seems to have trouble when I slow down finding the right gear to be in....anyone else have this problem? Replies to this message: concerned10 (Aug 10, 2009 3:41 pm) ransom777 (Aug 11, 2009 3:44 pm)

Replying to: ransom777 (Aug 10, 2009 3:25 pm) Ransom, I can't speak on behalf of the hesitation, but mine also has difficulty finding the proper gear at slow speeds (i.e. 30 mph). I took it in just last week to tell them that at 30 mph (for a consistent period of time), the RPM's fluctuate wildly. They said that they have updated software to correct such, and hooked it up to the computer to download the software. This seems to have fixed it at 30, but now seems to have a similar, but lesser, issue at 15 mph. Take it in and have it hooked up.   P.S. - My gas mileage is now logging in at 19.8 mpg, so I am now quite satisfied about that. Replies to this message: ransom777 (Aug 11, 2009 3:44 pm)

#300 of 300 Re: 2008 Yukon Hybrid Gas Mileage [bbooze] by patnwfla Oct 29, 2009 (10:18 pm)
Replying to: bbooze (Mar 31, 2009 6:09 am) I have had my Tahoe Hybrid since March 1, 07 and average 20.2 with 24k miles on it. Was averaging 21.4 until we took some interstate trips that I tend to drive 10+ over the speed limit and with wind resistance and cruise doesn't allow the truck to run in 4 cylinder mode much and really drops the mileage. I live in Fla so no warm up times needed but the A/C does cause the truck to run more gas than electric even at lower speeds.   I have been very happy with the Tahoe. Wife has a Lexus RX and we typically take the Tahoe on trips because it is more comfortable and a better ride.   We don't use the third row much and I typically will only have one of the seats in there.   I would definitely buy the Tahoe again.
