#68 of 128 still loving it! by markisliev Aug 10, 2007 (2:53 pm)
Hey skytop how much are they paying you? 4k miles on mine...still loving it! Folks who knock the 3.42 rear end do not understand overall gearing and just bitch because they hear "3.42". 6L80 has a very steep 1st gear giving a hole shot near the same as a 4.56 on the previous 4spd...gotta look at the tranny gearing as well...

Replying to: markisliev (Aug 10, 2007 2:53 pm) Markisliev: I had a conference phone call with GM engineering at my dealership. What I learned directly from GM turned my stomach. They have no fixes for the numerous computer related problems for at least 6 months. Read my other posts to see what hell my Denali put me through. If you don't believe me, it makes no difference to me. I post to alert those conscious folks who are alert and receptive. Deadheads, need not apply. If you really have a Denali, you too will ultimately become a victim. Mark my words.

Replying to: skytop1 (Aug 10, 2007 12:06 pm) Respectfully, if you are experiencing so many problems, you should persue some sort of Lemon Law relief that your state offers. Every manufacturer has had to 'buy back' vehicles that could not be repaired after a reasonable amount of time and attempts. No one is perfect and you seem to have purchased the proverbial 'can of worms'. Certainly there are deficiencies in both design and content from GM. But I have also heard that Toyota is presently suffering engine failures in their new Tundra 5.7 liter, due to cam shaft related problems. (Possibly as many as 30-40,000 motors at risk) Many other automobile companies including Toyota, recently designed engines that promoted a rapid build-up of sludge, resulting in engine failure. Honda had major problems with their tranmissions in their flagship Acura MDX and the list goes on to other manufacturers from there and is quite long. 16-17 million vehicles are sold each year; there's bound to be problems. It becomes unfortunate when it is compounded by more than 2 defects. I think all anyone can say to you at this point is to persue your legal remedy, be calm, try to patient and be and take the high road to be fair. I'm sure once your truck is repurchased by GM, you will find a more suitable match of vehicles. But electronics in our life and vehicles will be the bain of our existence. We all appreciate your insight and a heads-up warning for potential future concerns. I'm sure you have everyones attention here, but shiny black paint, chrome and the smell of corinthian leather has a way of putting the rest of us into the gas filled either tent.

Replying to: 1oldcarguy (Aug 10, 2007 3:58 pm) Yes, Toyota is also having problems. The engine problem is not about sludge. They had a supplier who did not anneal cam shaft billets properly and they prematurely failed. Toyota got on top of it, waranteed all the 31 (so far) effected engines and replaced them. Now I read that they are having transmission failures. The fact is that they step up to the plate and at least acknowledge the problem and actually make repairs or replacements. They don't lie and deceive the customer about the problems as GM has repeatedly done to me. But that is another story. Yes, GM has frustrated me to the point of driving me to describe my horror stories with them on these posts. Everything I have stated is 100% accurate. GM and their dealerships have no clue as to how to treat a customer. They have no idea how to keep a customer or his loyalty. GM and their dealerships are rank amateurs and rookies in customer relations. If you ever experienced Lexus, Accura, Mercedes or even Honda or Subaru service as I have, you would see how a customer is to be treated. It is no secret that GM is losing market share everyday to these other makers. Why? After sales service! Ask any customer of other makes and they will tell you how these other car manufacturers respect and regard them with top notch knowledgeable trained service and white glove treatment. GM has had 35 years since the first oil crisis to observe Asian car makers in action since Honda and Toyota got a foot hold on our shores. In all those years you would think GM would have half an ounce of brains to figure out how the Asian (and Euro makers) keep their customers coming back. But Nooooooo, not the brain trust at GM. Those noodle heads are running the company straight into the ground at 300 MPH. People are running, not walking away from GM and for damn good reason.

Not all exactly accurate. Toyota has no choice in this full size Pickup truck war but to bend over backwards and get these problems resolved. They have billions at stake with this new launch. Unfortunately now, it's all about the $$$ and saving face. They are the new poster boy and they would rather fly under the radar right now. Their quality has suffered substantially. It is not just truck transmissions either. Just ask the new Camry or Solara owner who bought units before Jan. of this year about their herky jerky transmissions that sometime leave you with a false neutral, just when you are trying to cross an intersection in front of that on coming semi. However, it was not long ago that Toyota systematically denied coverage to sludge victims, even when the customers provided evidence of 2500-3000 mile oil changes that were completed regularly at Toyota Dealerships. It was only with the beginnings of a class action law suit and publicity in Automotive News and other journals did they capitulate. How do you think those new Camry and Lexus owners felt in light of 2500 mile oil changes, a frozen motor and sorry, no warranty for you ? You must also remember when Mobil 1 first came out and advertised and implied 100k oil change test life ? We generally travel 10k miles before changes, but who can you believe ? Think Nissan handled the Z car premature tire wear problem any better ? That situation lasted for at least a couple of years if I remember correctly. Really upset people having to spend hundreds of dollars every few thousand miles on tires. I do not think there was ever an acceptable solution for those models. The alternative was listening to tire roar, and I mean ROAR. Or how about their power window motors prematurely wiping out their internal brushes? If you think it is hard and frustrating dealing with GM, try getting Honda to step up to the plate a week after your warranty runs out. We have friends with Nissan Titans that live at their respective dealerships and like you, say never again. Even today, Toyota dealers might tell you that if you buy a used Toyota that still has factory warranty remaining and you do not have a copy of timely oil changes completed by the prior owner(s); you're out of luck if you have a sludge engine failure. We have had many vehicles in our fleet, and with the exception of the 2004 Denali AWD Quadrasteer, its hard for me to say which one vehicle can be the 'perfect be all' 'to end all'. Even this model had a hokey rear diff and some minor component failures. But that experience is sure easier to tolerate than the 2005 Toyota Solara Convertible that soaked you everytime you open the drivers door while it was raining. Toyota never woke up to the fact that a simple rain channel on the convertible top would mitigate the situation. You can't fairly throw all GM dealerships under the bus. There are some very poor ones for sure, there are some good ones and there are most likely a majority of average, possibly uninspired ones. It's all changing now and it will be for the better. When it comes to customer satisfaction, Denial (ne denali) is still a big river in Egypt; and it ain't all GM's waterpark. After all is said and done, the dealership did not make the vehicle. Yet, you would hope and think that if there was a chance for some one of them being a hero to you, they would seize the opportunity. In the final analysis, we all secretely want and demand perfection. Especially when it come to planes, trains and automobiles. And that my friend is why Playboy still airbrushes all its centerfold photo's.... If only it was that easy. Replies to this message: obyone (Aug 10, 2007 6:39 pm)

Replying to: 1oldcarguy (Aug 10, 2007 6:29 pm) Another thing to remember. The labor times allowed to the dealer to diagnose and repair warranty items are well short of published times. I guess its a way for GM to squeeze the dealers. So its easy to understand why the service techs seldom are able to "duplicate" the problem and certainly will not go the extra yard to find it since its not in their best interest.

Replying to: skytop1 (Aug 10, 2007 12:06 pm) Wow.....I don't even know where to start skytop1. First off, you have obviously bought a rare "lemon" if half of what you say is true. I ordered my 07 Sierra Denali in May, and recieved it in June. I have 5,300 miles on it and I have had one problem......a noicy window (front passenger) and the dealership a. replaced the entire window regulator, b. changed my oil free, c. DETAILED my ENTIRE truck for free, and d. gave me a loaner Denali SUV for the day. I cannot imagine a moment in which I would have to repeatedly stomp my accelerator to avoid impending doom. If you want to avoid the 4 second relay, PUT THE TRUCK IN MANUAL MODE! The owners manual should plainly state that you must first outsmart the vehicle to properly use it. The 4 second relay is a safety mechanism. For instance, say you were on the highway and had cruise control set. You adjust your feet and stomp the accelerator accidentaly. You have 4 seconds to remove your feet before it actually engages. Without that safety, a clumsy foot(you obviously have one if you unlatched your hood with your foot while driving....I'll get to that later) mixed with a wet road and 403 hp, you might just end up backwards on your head. You mentioned stop and go traffic......do you actually floor it every time traffic moves? Are you that stupid? I drive in the country, off road, downtown Dallas, downtown Houston, ect. Houston is the third largest city in the US. I have no problems navigating traffic. I also don't floor it everytime traffic moves. In a sence, you are right. The 2007 GMC Seirra Denali's computer does not compensate for an idiot driver. You blatantly knew there was no A pillar grab bar when you bought the truck. YOUR PROBLEM. A/C problems sound like B/S to me. NEVER head of a problem like that in my life. SLOW? Are you serious? If you want something faster, buy a sportscar. My Denali chirps the tires 35 mph in manual mode with trac. cont. off. Or how about adding a chip, exhaust, and intake? You also knew how much power it had before you bought it. Unless you didn't test drive it first. Unlatching the hood? You really are a stupid person aren't you? The latch is inset into the panel and 6 inches off the floor. What the hell kind of foot manuvering were you doing? Sounds like you are retarded, or a liar. Where did you get the money for your Denali? I ask because I suspect you inherited the money........no company would pay someone as clearly incompetant and moronic as you, enough to afford a new Kia, let alone a Denali. Suggestion; the all new 2008 Caddilac Escalade EXT F*cking Retard Edition. One wheel, two buttons. Stop and Go. No confusing latches or levers....no shiny buttons or shifters. You truly are a complete idiot and I suggest the next time you post something on the internet, have a loved one read it first so you don't look stupid anymore.......

Replying to: guysykes (Aug 18, 2007 12:24 am) Guysykes: Clearly you are not the brightest or most aware posters here. If you read my posts, you would have a clear concise understanding of the myriad of factory defective problems my lemon is plagued with. And I trust you never adjust your feet while driving so you don't accidentally engage the stupidly placed hood lever with your sleeping foot. Yes, the lever should operate from the top so no foot contact will engage the switch. Maybe you can wrap your brain around that solution. But it is your obligation to be able to understand what is posted and I am not going to explain anything additionally. Update to problems: For the final last time, I brought my Denali in for service to have them attempt to fix the failing A/C, the defective transmission, a defective electric window switch causing a battery drain and the loose steering wheel. They only could "solve" the column problem and replace the switch. After three other dealerships claimed the loose steering wheel was 'normal' for the Denali, this dealer actually ordered a replacement column. They installed it. As I drove out of the dealership, I noticee the wheel was installed about 10 degrees out of true. It is very crooked. Oh yes, they also dinged my drivers door as an added benefit to true GM quality care and service. However, the ding is the very least of the problems and soon this tragic example of a truck will not be my problem. Enjoy you GM truck and their superb competant service.
#76 of 128 Would buy again... by markisliev Aug 18, 2007 (5:29 am)
Guysykes...I've been enjoying my ride very much also and would buy another no questions asked if I had to do it over again....not a single problem on this end. You can't please everyone. skytop1 is the only one I hear with problems...I think he should look into his lemon law rights and quit bitching. The Tundra is snapping CAM's and frying tranny's left and right, but he defends Toyota. Just think if he owned a Yota that had these problems. Like they said...buyers beware of paid bloggers!
#77 of 128 Delusions can be fun but reality ultimately bites by skytop1 Aug 18, 2007 (11:12 am)
Mark and other GM diehard hardheads: Keep up the spirit. There will always be those who refuse to see they are on a sinking ship and they are the ones that go down. Guess you can't read either because I never defended Toyota or any foreign make. My beef is exclusively with GM, GMC Denali and GM's very poor service. I have been burned by GM for the last time. Indeed, I have paid in cash, lost time and anguish. But you fellas can dance all you want celebrating your allegience to a dying company but GM is losing market share big time and continuously every day of the year. Why? Cause guys like me and countless others are running, not walking away from GM. Those are the facts, live with it. And when your Denali breaks and it will due to systemic defects GM incorporated into the computer intensive Denali design, remember my posts about the frustration dealing with GM incompetant service. You can enjoy living in your delusionary world all you want, but I have been to the GM alter and I can assure you and everyone else interested, it is no picnic. GM is the pits and a thoroughly poor company to deal with. What I stated factually and accurately will ring in your ears as you repeatedly have your truck serviced ad nauseum. GM Sierra Ad: "We examined everything. We overlooked nothing." Believe that crock of GM crap, and I have a great deal on a bridge in Brooklyn I can sell you.
