Personal comments are what base the review for others to see. Not negative Just a Honest Positive feedback

Replying to: lionclawz (Jul 14, 2007 7:30 pm) The choice was between the new Toyota and the new GM trucks. In spite of the rave reviews on the Tundra, I decided not to send my money on a trip to Tokyo and help the home town company. That was the underlying purpose of my selection and choice. However, this truck and GM have let me down. GM service, GM techs acknowlede my problems but do NOT have the fixes. For one example, the my '07 Denali has the brand new adaptive learning 6 speed tranny which is primarily controlled by computer and not just hydraulic pressure as older units. The software running the tranny computer firmware is seriously flawed and cannot cope or properly interpret very slow speed driving or decelerating conditions, or deceleration and then mild acceleration situations. It does not learn and sends conflicting commands to the tranny and the engine causing the engine to accelerate even though I am trying to stop. It also signals the engine to accelerate as you are stopping sending torque through the driveline as you try to brake and causing sizeable jolts from improper shifts. GM doe NOT have a fix now or in the immediate future. I have to live with a defective transmission that even creates unintended acceleration when stopping. What you think about my posts and your inane remarks are of little importance. These posts are not for you but for other victimized Denali owners and those considering the vehicle. I only wish this kind of info was available before I ordered my truck. The fact is that GM has placed into production a half baked not ready for prime time transmission. They sell it, they know it does not function properly, they have no clue or method of fixing it, but they put it into full production so they could induce people to buy their trucks. Shameful and a total lack of conscience!! They sacrificed their integrity for the buck but lost me as a customer in the process. Everyone buying this expensive truck is suffering with it. It's not General Motors to me anymore but rather, Private Motors.

Replying to: skytop1 (Jul 16, 2007 6:21 pm) Being on the verge of making a final decision on whether or not to purchase a Sierra Denali, I'm trying to find good, honest opinions on the vehicle. The vast majority of the printed and online reviews are positive. This last post has really made me think tho, so I'd like any other Denali owner's to step in and voice their opinions and experiences. I will appreciate the insight Thanks Replies to this message: skytop1 (Jul 18, 2007 8:56 am) 2007denali (Jul 18, 2007 9:06 am) dallasstb (Jul 18, 2007 10:01 am) 2007denali (Jul 18, 2007 10:33 am) and 1 more... vadaddy (Jul 20, 2007 12:53 pm) markisliev (Jul 20, 2007 2:40 pm)

Replying to: dallasstb (Jul 18, 2007 6:57 am) Look at my other posts regarding my vehicle problems. I am dismayed, disappointed and very disheartened by the entire experience with GM. Do you own due dilligence and you will make your own decision.

Replying to: dallasstb (Jul 18, 2007 6:57 am) I purchased an Onyx Black 2007 GMC Sierra Denali two weeks ago. It is AWD, with 20 inch chrome wheels, sunroof, heated steering wheel, and dealer installed chrome oval steps. Overall, it is an extremely nice truck and I am extremely pleased with the purchase. Skytop1 makes some valid points, but may have blown a few points out of proportion that would have made me think twice about purchasing mine if I had read his post prior to my purchase. First, the transmission does seem somewhat “confused.” I expected very smooth shifts out of a 6 speed, but have found that my previous truck, which was a 2004 Chevy Silverado LS, extended cab, short bed, 4.8L V8, 4 speed transmission, 2WD was much smoother. Second, to address the gas mileage, I’ve been unable to get near the 13city/19hwy claim made by GMC. I’ve tried my best to baby it (my wife has accused me of driving like my grandfather) and use cruise control, but no matter how I drive, I have found the gas mileage to be between 10 and 12 mpg. I am taking it on a road trip this weekend, so I’ll let you know how far below the 19 mpg claim it falls. My old Silverado was supposed to get 14city/17hwy, which it did. I could drive around all day with my foot in the gas tank and still do no worse than 13 mpg. All that being said, shame on GMC for the mpg claim, but seriously, when you pay $45,000 for a pickup with 403 horsepower, you should expect to pay for it at the pump and you should be able to afford the gas. To address ergonomic issues, headroom is lacking (perhaps due to the sunroof and I’m 6’1”) and the tilt steering wheel is a joke (and by the way, how about some telescoping action?). GM used the same design on the tilt wheel as they did on the 2004 Silverado and 2000 Deville I used to own. It’s weird because it worked on those two vehicles and doesn’t on the Denali. There is not an entry assist “A” pillar handle, which would have been nice, but I’ve not found it to be a problem with my dealer installed steps (which look nice too). I haven’t had any trim pieces fall off and I’ve found no problems with the build quality. The instrument panel cluster is actually quite easy to read and very attractive. I personally love the center console. If you want perfection in a pick up truck, wait until Lexus comes out with one (don’t hold your breath). Until then, there is no nicer or better production truck on the planet. I’m sure GM will get the computer bugs fixed with the transmission through a recall in a few months and the rest of the issues pretty much fall into the “so what” category. I think that you take the good with the bad, and trust me this truck has a lot of good without too much bad. If I was to grade this truck on a 100 point scale with 100 being the best, it would score a 95. My suggestion to Skytop1, and trust me, I hate to say it, go trade the Denali for a Toyota, life’s too short to be that upset with your truck.

Replying to: 2007denali (Jul 18, 2007 9:06 am) Thanks 2007Denali. Your detailed description is very helpful. You seem to have purchased the exact configuration that I'm looking at right now, even with the silly heated steering wheel. Also, I'm around 6-2, so your note about the head clearance is much appreciated. It looks like I'd be safe as long as I'm not wearing a hard hat. I'm a little concerned about the transmission and gas mileage. I felt that GMC was being a little aggressive with the 19MPG estimate they published for the 6.2L engine, but it is still disappointing to hear. My current vehicle is a 2001 Suburban and it gets about 16-17 MPG average for my usage with the 5.3L V8. I was hoping for something at least close to that. The new-six speed transmission problem is also unfortunate. BUT I've read that the Tundra's are having similar or worse problems with their version of the six-speed. I hope it is a correctable problem. The 100,000 mile drivetrain warranty gives me some comfort in that regard. Are there any other of Skytop1's comments on the interiors that nag at you? Thanks again for your assessment, 2007Denali, and I would appreciate anyone other Denali owners' comments about the vehicle.

Replying to: dallasstb (Jul 18, 2007 10:01 am) At 6'2" headroom WILL BE TIGHT. Have you test driven one? If there is not one in your local market, you'll get a pretty good feel for ergonomics and headroom from a loaded Sierra w/sunroof. You might consider no sunroof, which should add an inch maybe two of headroom. I remember when the Cadillac XLR came out. I went to the dealer (somewhat dreaming) to test drive one. They had one on the showroom floor and I sat down in it with the top down. I went to close the hardtop and the roof hit me in the head (with the seat full down and back). I swear you've got to be less than 5'10" to drive one of those! The interior quality is the best I've ever seen from GM. It's not quite like a Lexus LS460 or a Mercedes S class, but it's darn close, and hey it's like $20K less too. I remember sitting in a brand new 2004 Dodge Ram one time and opening the ash tray and having it fall off in my hand, certainly nothing like that has happened in the first 600 miles on my Denali.
