Replying to: tourguide (Sep 01, 2005 3:01 pm) for putting this ... about the whole approach to fuel effeciency. GM had (perhaps still has) an opportunity to provide far and away class leading fuel effeciency and instead they decide to provide more power through a larger V8. AS IF the 5.3 of today WASN'T large enough! At last report the new and improved Tahoe/Yukon is slated to receive a 6.0 liter motor! So GM has decided to take the effeciency gains from their new Displacement On Demand technology and drop in more power - because we just didn't have enough before! Yes, this was the wisdom that came out of GM headquarters in this - the time of $3.50 (and climbing) a gallon regular unleaded. Let me put this another way. Instead of going for the gold - in fuel effeciency - GM settles for a pitiful 2.1 mpg improvement in fuel economy. This assumes the optomistic prediction that Edmunds quotes of a full 15% effeciency gain and 14 mpg city driving. No wonder GM and the other domestic auto makers are in such trouble. Anybody else still wonder why Toyota is posting such huge sales increases? I'm afraid you need to do your homework. GM leads the class in standard hp yes, but they also lead the class in fuel efficiency. That's right, the gmt900 SUV's achieve better mpg than Ford, Dodge, Nissan, or your beloved Toyota. You sit here and criticize the fact that GM isn't doing enough to increase the fuel efficiency of their large trucks and Suv's, and you say that Toyota is better, and no wonder they are doing better?! First of all, GM far outsells Toyota in large SUV and truck sales,secndly, Toyota offers a much smaller engine that gets worse mpg, and third, lets not forget that Toyota is now going t o offer a 5.7 L engine in their redesigned Tundra and presumably the Sequoia when it's redesigned, and they have made no attempt to offer such fuel saving technology as DOD. Add to that the fact that GM will have hybrid versions of these vehicles in a matter of months, and these engines can be run on ethanol( a clean burning, cheaper, American made fuel), and it's very clear that GM's large SUV's and trucks are superior in fuel efficiency and power to Toyota's large SUV's and trucks. |

Replying to: tourguide (Sep 01, 2005 3:01 pm) As I read of your diaappointment, I was compelled to reply.Even though your statemnts were made in Sept. 05, long before the actual release of the various GMT900 SUVs, I felt a few more comments to your statements were in order. As the previous owner of 2 V8 Tundra 4 x 4s and now the own of a 2007 GMC Yukon, I am totally impressed with the GM fuel economy vs the Tundra fuel economy. Over 6 years of Tundra ownership, I averaged +/- 14.5mpg in all conditions.Currently, I am averaging 16.1 MPG with the 5.3 Yukon after 3000 miles. I am averaging 23.4 with my GM 5.7L Corvette. I never averaged that high with my V6 Camry! Yes, reliability and resale may be other topics for debate, but time will tell. GM has improved, Toyota is flat. |

Replying to: dettltz (Jun 13, 2006 6:59 pm) The 4.8 is the "econo" engine, available in 2wd LS versions. The Denali will remain with the 6.2, and the Suburban 2500 will have the 6.0. |

Replying to: dettltz (May 27, 2006 8:22 am) Next time, you exit the vehicle, have your windows down and lock up your truck. Then listen to the noise from the outside after 5-10 minutes. GM vehicles used to have option that let you listen to radio even with ignition key is out as long as you still in the vehicle. Now if you are out of the vehicle, everything should shut down gradually after some minutes to save battery. If the DVD keeps on spinning all the time, the longevity of the battery will be affected. jt |

Replying to: tdoh (Jun 13, 2006 10:36 am) Back to the Tahoe 15/21mpg 320hp 340ft-lbs Other 4x4 with standard engines Toyota Sequoia 15/17mpg 273hp 314 ft-lbs Nissan Armada 13/18mpg 305hp 385 ft-lbs Ford Expedition 14/18mpg 300hp 365 ft-lbs The Sequoia's tow rating is 2000lbs lighter than all the others. I'd give up the 30ish ft-lbs of torque for the extra 3 or 4 mpg. If you need your exra HP and torque well the Denali should do it then...13/19mpg and 380hp 417 ft-lbs. Highway mpg still better than the competition. |

| Has anyone experienced a situation where their 2003 (or other similar year/mileage) Yukon had the front differential need to be replaced, along with the front wheel bearings at 85,000 mi? This just recently took us by surprise after buying it used with no known defects and a clean maintenance record (corporate fleet). The dealer tells us that we need to replace the diff. and at least one wheel bearing....$2100!.....This isn't an AWD Yukon, just 4 WD on demand. Any thoughts? Any cheaper solutions? Any warranty? Would love to hear some ideas and comments. | |
