Intake manifold Gasket at 127000 miles (I knew this when I bought it)
Driver side heated seat at 127000 (no biggie)
The engine leaks a little oil out of the rubber lines (Very common among 4.3L and 5.7L (350) GM motors) at 127000. Main Seals are still good.
Steering hub is loose-needs replaced- in which I haven't done yet. I'll get to it this summer.
The Rear drive-shaft slip yoke went bad (So they thought)
Overall, good vehicle; Especially when comparing to a price tag of the Cadillac Escalade which is the same exact vehicle in 1999, expect the logos and front end) for about a price tag of $3000 less.
In referral to the slip yoke, Every time I come to a stop I get a vibration upon the full stop. It also shakes and (clinks) as soon as I let off of the brake. I thought it was my U-Joints. Replaced those to no luck. I took the vehicle to the dealer after beating myself up. To which they put grease in the Slip yoke that attaches to the rear drive shaft on the transmission (transfer case) end. To which it fixed for about 300 miles. I put a micrometer on both the old and new slip yokes to find the splines where both the same size within.0009 of an inch. Less than 1/1000. Before installing I called the Dealership and they said that it was the problem even if they measured the same size. So, I decided to replace to no luck. I still have the problem today with no Bulletins or anyone around being able to figure out what the problem is.
This is the Wife's vehicle and as long as I'm around to fix the Minor problems that pop-up from time to time. She's happy with it. Say's she would only trade it for a Toyota 4-runner and that's it.--Keep dreaming.-American all the way. Especially when buying parts. :-)
Hate the 10-16 MPG gas.-- Give some take some :-)
Note to the editor: I'm very happy with the vehicle. :-)
I have a 1999 Denali. I have had problems since the beginning. I have replaced the starter, fuel pump, brakes all around, and the spark plug wires. I have also have noises in the engine, steering column and underneath the vehicle that no one seems to be able to figure out.
Now I have electrical problems on top of that. Neither the heated seats nor the heater works. The radio, windshield wipers, and windows work when they want. Now the engine light is on after a tune up. If anyone else is having the same problems please let me know.
...I am thinking to buy the same kind of Yukon Denali 1999 you just described. The guy honestly told me all the problems with it, which sounds kind of the same as yours. The fuel pump needs to be replaced, the suspension has some problem and the U joints (ball joints) need to get fixed. He is asking $7000 for the Denali..
Do you think would be a good deal as a fix up? or are these problems to expensive to fix.
Which should be the case, after all it is American. "
but give you r opinion much welcomed.
Oops, careful, the U-joint is different than the ball joint. I just wanted to point that out so you aren't surprised at having to pay to fix two different things. The U-joint stands for universal joint. This is the flexible part that connects the drive shaft to the differential and to the transmission or transfer case. These are relatively simple to change, and shouldn't be that expensive (unless there is something extra special about a Denali). On the other hand, the ball joints are the ball-and-socket joints that essentially connect the wheel spindle assembly to the frame. To replace ball joints (2 upper and 2 lower), the whole wheel assembly down to the bare spindle that the bearings ride on has to be taken apart, so it's typically an expensive, complicated job. $800 on an older 4x4, and probably more on something like a Denali. You may well be looking at a couple of thousand dollars of repairs. On the other hand, that's probably why the guy is only asking $7,000 for a relatively new luxury SUV.
My 99 Denali seems to slow dramatically when I take my foot off the brake. It almost seems like the brake is still on. Usually a car will slow then sort of release. anyone else have the same?
I have a 1999 Yukon Denali (79k miles) and just replaced the fuel pump ($700) at the dealership. The dealer wanted $850 for this repair, but I was firm about paying less telling them they were not offering competitive rates.
The steering column makes noises like the one metioned by another commenter. I cannot duplicate this problem when taking it in for repair. The stereo periodically turns off on its own and the only known way to fix the problem is for me to press the electric door lock. I need a tune up, but do not want to pay the dealer another $700. Any suggestions?
I have owned my 99 Yukon Denali for a year now and the odometer is sitting at 77k. The only problems that I have noticed are a weak suspension and some electrical problems. The rear-heated seats seemed to have a mind of their own and the AC/Heater blower doesn't always want to work on anything, but the highest setting. I took it to the dealer for warranty maintenance and they replaced the heating elements in the seats, and put in a new blower motor. I was happier with the older blower motor after I did a little troubleshooting of my own and realized the switch is where the problem was. I had to replace the Delco radio after it cut out and so far everything is in working order. The only self-maintenance that I had to take care of right away was the bushings for the front doors. The Denali has some of the heaviest doors I have every dealt with amd the drivers door had to be slammed to close completely. New bushings did the trick for that problem though. I also had to replace a manifold exhaust gasket after I noticed it leaking last winter. This truck doesn't have the smoothest ride of all the trucks I have owned, however it does handle well in the snow and 4-wheel drive is excellent. I'm going to change my leaf springs to increase my towing capacity and that should be one of the last things I change. It was a good buy and the routine maintenance is fairly easy to keep up with and perform. My wife and I miss the full size of the XL or Suburban, but the Yukon Denali is a good trade for the features is holds. The power of the 5.7L 350 is awesome and I have a speed let off greater than most vehicles I have owned, but for the ice and snow where I drive it is a welcome blessing. I would also add; that out of all the GMC trucks that I have owned this one seems to have the best anti-lock breaks that I have ever seen. Many GMC models have serious hesitation for stopping and the Yukon is right on the money for every stop I have had to make. I would recommend this vehicle to anyone that is looking for a great travel vehicle.
I have a 1999 Yukon and I was having the same problem of applying the brakes and then when I would step on the gas I would get a clunking noise. This started at around 30,000 miles so I took it to the dealership and they said there was a service bulletin and the yoke where the drive shaft attaches had the wrong type of grease. They re-greased it and it has been good for 100,000 miles and now the problem is back. If I find out what kind of grease I will post it.
You know what, I have had the same problems ever since I bought my car (a 2000 GMC Yukon Denali). It's been messed up with the electrical problems. When it starts to mess up, my windows don't roll down and my radio shuts off completely. It's freakin wierd. If you guys know what that problem might be, let me know because I'm not paying 100 bucks to get it diagnosed. Hit me up on my email if you have the same problems with your Yukon Denali...

My name is rjay.
I have a 2001 Denali with 75K on the odometer. My vehicle has a loud whine from the front differential while cruising and gets louder under acceleration or when you lift off the throttle. Seems to be loudest at around 45 MPH. Anyone experience this?
I have a 99 Yukon Denali, and my radio, windows & wipers did the same thing!! They worked when they wanted to.
I had my boyfriend open up the center console, and we played around with wires until we found the two that affected those areas. We added an extra wire between the two and everything worked. The only downside now is my dome lights, horn, alarm and headlights (I have to manually turn them on). Whatever, it's better than using rain-ex all the time and having no radio.
I am having my entire electrical system redone, so if I find out how to get everything working at once, I'll let you know.
To everyone with electrical problems in Escalades and Denalis, I have a 2000 Escalade and components like the power windows, radio, wipers, cruise control, and the fog lights work when they feel like it. I have replaced every fuse and wiring harness with no luck. I have to take it to an automotive electrical specialist, unless anyone knows what is wrong!
Recently I just purchased my 1999 GMC Yukon Denali, with 114,000 miles on it. I purchased it from a private owner who assured me that the truck was in excellent running condition. The truck is beautiful with 22" rims, and my purchase was $11,000.00. My problem is that since I purchase the truck I had to already replace the Fuel Pump ($800) and the Water Pump ($600). I knew repairs were to happen soon to me, but did not know that the expense would be so greatly in such a short time. The truck runs fine now, but I don't feel that it has the power that it should have. However, all and all, after I have made these repairs, I still feel that I have a great vehicle.
I have a 1999 Yukon Denali with 85,000 miles. It keeps stalling on me while I am driving. I have taken it to the shop and they tried for 2 days and couldn't figure out what was wrong. I have replaced the fuel pump relay and that didn't work. any suggestions?
I have had my 2000 Yukon Denali for almost three years and it has been relatively problem free till the introduction of ethanol to the fuel system. Now it hesitates, the check engine light constantly comes on, and it seems as if it is going to die out when I'm at a red light. I too have found that the eletrical problem is coming from the console, but I have yet to learn how to fix it. Any suggestions on any of the above? Please post them.
