2007 and newer Chevrolet Tahoe and GMC Yukon



  • I just crossed the 27,000 mile mark with my my 07, and its Wranglers still have lots and lots of tread on them.

    If I'm picturing correctly what you are saying, it sounds like there might be a design flaw. Tahoes have an indented area in the rear door molding to prevent them from touching. It could also have something to do with the hinge alignment; maybe the wind could have caused the door to open one time, hard and mess up alignment. That happened to a Pontiac Grand Am we once owned and we had to take it to a body shop for them to work their magic.

    Do you mean the thing that holds the rubber part of wiper blade?

    I never mess around replacing just the rubber part anymore - still have the old GM blades - but -

    Putting Michelin blades on solved my problem - not worth messing with a trip to the dealer if its just a wiper replacement - but if its the complete arm (part that is bolted on to the vehicle) it may be worth the trouble.
  • Hey Everyone,

    Just got my first chance to use Ethanol. I only had half a tank of ethanol (didn't notice the station had it at first). Anyways, I liked the way it worked. It was a little higher in price than I exprected, but I also didn't notice a big drop in MPG as I expected. Basically from LA to Las Vegas I got about 17.5MPG on regular unleaded and on the return trip from Vegas to LA I got about 17MPG with half a tank of E85. I would normally attribute the .5MPG drop to the way I am driving home vs. to Vegas (kinda crazy on the way home with getting around slower traffic).

    So, now I'm just waiting for some ethanol to come up locally to me in Los Angeles.

  • I spoke to GM customer service today 12/27 and they said that the whistle was normal and the service bullitian # pip 3086A says do not fix .any others with this problem or do have the only whistleing chevrolet subn made if so im going to be on tv .

    Did you get E10 or E85? E85 will knock mpg down about 20-25%. Ethanol has about 25-30% less energy than gasoline.
  • It was E85, and I expected about a 20% drop, but I didn't get it, it didn't seem to drop at all.

    i have an 07 Denali and this happened to me several months ago. Front drivers door caught the front quarter panel and scraped the paint off. Dealer told me that the door had become misaligned and that it happens from time to time. They repainted it and realigned the door and I have had no other problems. :shades:
  • Brian,

    YES!! I have an 07 Tahoe and the GM doc# is 1974648. It was labeled as "Power steering high pitched whistle noise heard in any gear with vehicle warm" #06-02-32-010A Dated 5/22/07.

    No fix available at this time.

    The cause is internal to the steering gear. Engineering is currently investigating the cause of this noise and working to develop a correction.

    I called GM and was real pissed about this. Call them up and complain, I got a year of free maint. out of them. The sound is driving me nuts, all the dealer could tell me is to turn the radio up.

  • Dave & Brian,

    Keep trying with your dealer. My dealer in Nashville, TN, Jim Reed Chevrolet, did the right thing and replaced the steering gear mechanism, and that DID FIX THE PROBLEM!

    GM must not want to admit it will fix it. Otherwise it will cost them millions to recall all the vehicles with the same mechanism and replace it.

    I know what the bulletin says. My dealer showed it to me too. But I convinced them to replace it anyway, and they did, and it worked!

    So tell your service managers to call the service manager at Jim Reed Chevrolet in Nashville, TN.

    But what has been getting me since about 6k miles is that my brakes squeal at slow rolling and barely applying the brakes (like you would in slow traffic). It drives me absolutely nuts, but the dealer won't fix that. They say it's a maintenance issue. So I have a service station replace the pads for me every 5k miles and that solves the problem temporarily.

    Now with 37k miles (and out of warranty), the brakes are the only problem I have with the vehicle. I'll be checking out the new Sequoias in a year or so.

    What did GMC come back with regardint the Recycle issue? I took mine in to GMC here in Houston, and they told me that it is suppose to let some outside air. I think its BS, becuase I never smell the persons exhaust in front of me in any other car that I drive, including my wifes Honda Accord. Anyone out there have this problem??
  • obyoneobyone Posts: 8,054
    By industry code, the HVAC unit needs to allow a minimum of 15% fresh air even under recycle mode. That's just to ensure you don't run out of oxygen with a car full of "heavy" breathers.
  • That weird, because I turn my Recycle on when I start smelling exhaust from the outside and the smell goes away. Maybe you compressor isn't going on when you hit the recycle button, because I've always had the impression that having the air going through the compressor removes some of the inpurities from the outside. I may be wrong though...
  • Hey, does anyone know if it is bad to keep a Tahoe in towing mode all the time? I read something on a message board about it helping the car get into and staying in V4 mode, and I've been testing it and I seem to be getting .5mpg to 1mpg better performance with towing mode always on.. Any input from anyone?
  • 73shark73shark Posts: 325
    About the only way the A/C is going to remove impurities is if the evaporator is wet, which it usually is in the summer during high humidity conditions, and there is a lot of particulate matter (dust) in the air.

    I had same brake squeal problem on my Corvette. Some repeated HARD braking solved the problem. With new pads you may want to review this post and maybe give the break-in process a try.
  • I have a 2007 Yukon (purchased 9/06) with factory installed remote start. Until recently the car would respond to the keyfob from about 100 ft. Now it will only respond when you are within 5 ft of the car. This happens with both keyfobs. I have replaced the keyfob battery (which the manual says should last 4 years) but have gotten no improvement. This kind of makes having remote start useless if I have to go out in the cold to make it work.

    Any ideas?
  • Have you tried starting the car in different locations; work, home, shopping mall? If you Tahoe is sitting in a strong RF field caused by other devices, it can "confuse" the on board receiver.
  • just got lower grille for my sons 2007 yukon. Instructions are poor and we are not handy. It is the bolt on grille. Any suggestions? It would appear we have to remove the entire lower license plate plastic?? Then does it go back on? Thanks for any help. We are mechanically challanged!!
  • I have heard of that but it's been happening all the way as I drive cross country.
  • I just did roundtrip from Austin-Montana over holidays, with my 08 LT3 and averaged 19.5MPG at 80~MPH using 85 octane typical. I had one tank of E85 ethanol in Colorado, and only got 17.5MPG on that tank. Price was about 20 cents lower, but I also thought the preformance lagged a bit on the ethanol vs regular.
  • Holy Hanna, What engine do you have? The best I've seen in my 07 Tahoe is 18 at 70mph. Do you have the engine that kicks down to 4 cylenders?

    The 2007 Yukon Remote Control Start Antenna and assembly is located at the Driver side rear D-piler near the tailgate behind the interior molding. You may want to check the connections there...

    My 2007 Z-71 4x4 Tahoe is used mostly for longer trips - this is my 3rd Tahoe - also owned a 1998 and a 2006 -

    One of the things I liked the most about the having a Tahoe on a long trip is the confidence it gives me when the weather turns ugly.

    Yesterday I was on such a trip - had to drive for 3 hours in a pretty good rain storm -which at times was a complete downpour.

    I wish the wipers had a faster setting - at times they would not clear the windshield.

    But my questions are -

    The side windows seem to become very hard to see out of - its like the rain water builds up on them during heavy rain - my other Tahoe never - no matter how hard it was raining had this problem - I was driving 60-65 MPH - at times I it was so bad I could not even see the side view mirror.

    I can hear water dripping - not sure exactly where the sound is coming from - but its like the water building up on the side windows is dripping down inside the door - no leaks or anything - just the annoying sound of water dripping - very strange to hear this at 60+ MPH -

    The rear window wiper needs to be on all the time to keep the rear window clear - its always covered with rain - even after the rain has stopped and the road is just wet - the window still becomes covered with junk.

    I drove my 2006 Tahoe for 50,000 miles and rarely used the rear windshield wiper - my 1998 Tahoe did not even have a rear wiper and I do not ever recall having a problem seeing out the back window.

    I put a bug/stone deflector on the hood - I do not think that should make any difference - but maybe it does.

    Rain-X is your friend. Recommend using on all four sides.

    If it was raining so hard that your wipers weren't clearing the W/S, then it's time to put 'er on the shoulder and stop.

    Can someone advice where I can find either GM or after market Transmission oil pan (and front and rear axle covers) for the 2007 Yukon Denali (6.2 Engine) specifically with an oil drain plug build-in to the pan/cover?
  • Has anyone had any of these problems with their 07 Yukon/Tahoe? The radio makes a loud popping noise intermittently, The doors will intermittently unlock themselves, The XM source on the radio display will completely disappear as if the radio does not even have an XM function, and the biggest problem is that there is a clunk that comes from the rear end after I stop. Sometimes it happens immediately, sometimes several seconds after I stop. Seems that something is binding up when I stop and then releases as the brake pressure is released. I took this to the dealer and of course they could not find any electrical problems and told me the rear end noise was normal (BULL).
  • Did you ever get a resolution to the problem with the "zap" sound? I have had this problem with my Yukon since new and the dealer acts like he has never heard of this problem. Of course, the very day I picked it up from the dealer, it made the noise.
  • I think the nicest ones out there are the Mag-Hytec covers. I used them all over on my Dodge Ram Turbodiesel. Beside being functional, they are nice to look at and beautifully made. They make a large assortment of pan and differential covers, and all use O-rings eliminating the need for RTV goop. Expensive...but you get what you pay for.
