I have owned a 2000 chevy tahoe, the year the current model year came out, and I have over 150,000 miles on it and it is running GREAT!!! No problems at all. I have owned GM SUV's all my life and they are great!

I am in the market for a new SUV as well (currently own the GX470) and have had to place my decision on hold pending the arrival of some basic safety requirements - rear airbags. I was very disappointed that none of the GM products offered this as standard equipment hence the GX. Now I am searching again and am also leery of the quality of the new Yukes/GM products.
 
Also own a BMW 7 series and have really enjoyed it. The best part is the warranty and maintenance. I hand the keys to the dealer, they give me a replacement vehicle and call me when everything is done. No cost to me other than time and the best part - no headaches. Anybody hear of GM doing something similar?
 
Would love to know what you decide to do as I have never owned an American vehicle for fear of the quality.

2006 Tahoe - dissapointing towing by louis4

4 weeks ago, I traded my faithful (250K miles) 1996 Tahoe for a new 2006 model. I love everything about this new vehicle, except the disappointing towing experience as compared to my '96 model.
 
For years I have towed a trailer, up to 4,500 lbs. and never felt short on power with the '96 model.
 
The first two towing trips with the '06 model, and only 2,000 lbs produced disappointing gas mileage (the vehicle shifts down to 2nd gear for just a moderate incline or moderate head wind) but made me feel there is no towing muscle under the hood.
 
We put a converter back performance exhaust ($265 installed) in the vehicle and are planning to add the performance chip ($365) when it becomes available.
 
I realize I have gone from a 5.7 liter to a 5.3 liter engine but did not expect that much loss in towing performance.
 
Will the power chip even come close to providing a remedy?
 
Am I on the wrong track trying to spruce up the '06 Tahoe to make it have similar power than the '96 model?
 
Using the vehicle also for family, I am trying to avoid purchasing a truck. Is there any way around, or do I simply have to get a truck, maybe a duramax diesel?
 
Thank you for your insight and suggestions.

I am a car rookie. Don't understand GX?
 
Thanks for clarifying.

Yes Arlington Tx will be building the new 2007 Yukon and Tahoe. also Janesville wis. will also be building the same. Arlingtion startes Dec 5 2005. and Janesville will start Jan 9 2006. They have been building some 2007 modes for show and test drive for the gm big shots. Janesvilles has build about 200 modes so far.

I've noticed the same issues with my '00 Suburban 4x4 3.73 rear end with tow package. The 5.3 just doesn't produce enough torque at low rpm and the gear ratios are to tall for heavy towing (wish I had 4.10s).
 
The 5.7 had less hp, but it did have more torque. My boat weighs between 4500-5000lbs depending on fuel and gear. When hitting the hills I have go 80mph down so I can maintain any speed going back up. What is really sad is my previous tow vehicle was an 01 Nissan Pathfinder (3.5 v6) and it would tow my boat up hills better than my v8 powered Suburban. Even though both vehicles have similar power to weight ratios, the Pathfinder had more aggressive gearing along with an engine that developed its torque at a lower rpm.

My guess is you got the wrong axle ratio. The standard ratio is used to improve fuel economy, not towing performance. The EPA rating are higher provided less than 33% of the vehicle are sold with the performance axle ratio. When I tested Suburbans in 2001 before my purchase, there was a big difference between the 3.73 and 4.10 axle ratios in performance. They have gone to a taller ratio since then which hurts performance even more. Fortunately, the 4.10 axle has been kept as a $50 option (it used to be free). You can change the gears to change the ratio, but it is MUCH more expensive to do after the fact. Try to find a vehicle with the other axle ratio and compare them.

My 2005 Yukon XL came with the standard 3.42. It feels plenty fast to me, but I've never driven the other. I don't do any heavy towing, but still the capacity is around 7500 lbs. The lower gears don't make a lot of difference on paper, either for towing or fuel economy, but I would like to drive one with a 4.10 and see how much quicker it feels. Regardless I would probably stick with the standard 3.42 since I am driving like a Grandpa lately to keep it over 18 mpg. It can still jump when I need it to.
 
Note that when they dropped the standard gear from 3.73 to 3.42, they also added about 10 hp and lb/ft, so that may help offset it.
 
Have they published this info for the next generation yet? I wonder how much of that fuel economy improvement is attributable to aerodynamics and engine efficiency versus even lower gearing and playing with the numbers to get a good-looking average for the press materials.

One thing that will help a lot is the 6 speed automatic. Unfortunately, it is only available on the upper end models.
