Denali Problems

Denali_bug · August 25, 2007

hi folks,

Thank's god , finally i'm allowed to post my topic .... i have 07 Yukon Denali Although interior materials are cheep , but gm did a great job on design , i experince some problems i would refer it to the computer i guess, when i'm cruising 35-60 mph and apply the gas pedal to increase the speed to takeover a car on a higway , i almost get killed , the RPM lower down and there is a lack of power for two secounds then the trans. shiffted for the lower gear !!!

Another thing is when you move from a stop , you feel the car is too heavy and the engine noise are tirrple , on the other hand my friend have 4speed yukon SLE 07 lighter and faster !!!!

finally , the brakes are junk , for this power .

any comments

Thanks

I am not certain what you are trying to say. I am on my 3rd Denali and the 07 is a great vehicle and by far the best of the three. I have no idea why you are getting a power lag as mine is not showing the same trait. It has a world more power than the older ones.

I enjoy the new exhaust noise as it sounds as good as it runs. I would love a face off with your friends 4 spd Yukon 07.

Good luck,

Try two things to see what a great design GM provided your bargain Denali with:

1. While cruising between 35 and 60, just tip into (lightly accelerate) the gas pedal and watch what happens. The engine will actually decrease in RPMS. Only GM makes a vehicle that slows down when you apply gas. You can thank the GM computer geeks for this screw up. Rediculous!

2. In an emergency situation, you might stomp on the accelerator pedal to avoid an oncoming vehicle, then lift your foot and then stomp again as you evade a dangerous scenario. Now you try stomping on the gas pedal about two to three second intervals. Try this on the highway as well. The transmission goes crazy. And the lag times are remarkably long. You have no safety margin in the GMC Denali due to delayed engine/tranny response. The drive by wire computer you have gets totally confused and it ceases taking any signals from the gas pedal. You are dead meat.
