    it might be a bad regulator on the cruise control. i would get that checked. until then dont use it. and the heated seats probably had a short in the wiring. the wires are probably disconnected or cut. id have to see the suv to make sure. but i think i am correct

  • I too have a 2007 Yukon XL. The car has been a lemon from the get go. Ours ate oil like crazy for a year(only 2 years old at time with less than 50k miles). Took it to several different dealerships, fought with the very unhelpful GM service reps for close to a year, kept getting the run around about how it was normal for a car(even a new one), to eat several quarts of oil between regular oil changes. Don't know how I finally managed to get them to take responsibility for the issue, but ultimately my local dealership was given the go ahead to fix the issue. Took them 5 weeks, and they rebuilt the whole engine. I should mention that the transmission also failed at 28k miles, can't even recall what they had to do to it. After the engine problem, we decided to park the thing and use it very sparingly. Weather has been bad here in Missouri and have needed a 4 wheel drive. Start driving it more regularly and now we have this exact same problem, with the Service Stabilitrack, reduced engine power. Then the vehicle completely shuts down. This has the potential to be a very deadly issue and reading all of the posts in this thread, I am really concerned with the chances of this being handled fairly. When I called my GM service dept, they were very well aware of this issue, but could not find that my VIN # was approved for this apparent fix that GM is offering to do? They want $100 to diagnose(O'Reilly already did that for free) and then will throw me to the wolves at GM to fight it out. We are not in a position to throw hundreds or thousands of dollars at an issue that GM is apparently well aware that they have. I just can not believe with the thousands of people having the same problem that they have not voluntarily issued recalls and offered to rectify it at their expense. I Filed a complaint with the NHTSA, and hope that everyone else does too!

    this problem is very serious. why gm is not helpful i dont know. i will ccheck all data for any recalls

  • Everybody needs to call the NHTSA and file a complaint. This is a huge safety issue that GM is not addressing!! 1-888-327-4236. My 2008 Impala cut out on me yesterday on the highway,, " Reduced Engine Power",, scared the heck out of me. And of course GM says they know nothing about this issue. Really?? Looking into a lawyer for a class action law suit,, this is ridiculous!!

  • jordan40jordan40 farmersville, nyPosts: 109

    it is this is rediculous. put a scanner to it and put the trouble codes on the forum and ill put them in to all data

  • I don't know what you mean,, put the scanner to it???

  • jordan40jordan40 farmersville, nyPosts: 109

    some shops and people have these scanners that you hook up to the vehicle. if you look under the dash on the driver side you see this connector. you hook the scanner to that connector and the trouble codes will show up.

  • TSB # 11-06-04-007C explains it all. Call your local GM dealer and ask him about it. There. Done.

    Better idea biffthebassman

  • @biffthenassman. That sure doesn't explain much to me because I have an 04 Tahoe. The posting you put is for 2008-2011.
  • jordan40jordan40 farmersville, nyPosts: 109

  • jordan40jordan40 farmersville, nyPosts: 109

    i just got my first 2007 Yukon. and it had the reduced engine power message. when i got home i went into my shop and hooked the scanner up. could not find anything. So i am taking the engine out and putting a 72 chevy suburban engine in it

    I am doing an engine swap with a trusty late 70's chevy suburban. if you dont have that vehicle i would take it to a local shop that knows you, and ask them to do an engine rebuild. i had this happen to me a few times. my used 2007 yukon has the same problem. so i have it parked in my garage next to my subuurban. hopes this solves the problem

    go to google and search: Technical Service Bulletins for 2004 Chevy Tahoe

  • Yes I have the same problem and it isn't easy for me to just change out the motor or even get it fixed because no one can narrow down the problem to tell me what to fix. I can't afford to "try" to replace several parts to see if that fixes the problem. Someone at GM needs to narrow it down already and find out what the exact problem is so that I can fix it and be done. I am a single mom of three boys that purchased this vehicle for 14000! First someone said it is the throttle body. Then the throttle body harness. Then check the stabilitrac. Then check the cruise? I can't replace all of these things and hope one of them is the problem!! GM is doing owners of these vehicles a huge disservice by knowing that there has been a problem all along. It is a deadly problem when on the highway and needs to be addressed.

    Hello lalaleeza,

    We definitely recognize your frustration with this situation, and apologize that you are still experiencing issues with your vehicle after all this time. We would be more than happy to set up a case for you within our system and look into a possible resolution to your concerns. If interested, please message us your full contact information, VIN, exact mileage, and preferred dealership.

    Thank you,

    Amber N. GM Customer Care

  • Amber N. I already have a case and I was told there is nothing GM will do or can do to help. I am not the first owner and the mileage is over the "special coverage" that the previous owner/owners never fixed because this issue has been sporadic. The special coverage doesn't cover past a certain mileage. Just because this problem that GM has known about for YEARS didn't happen with the other owners and is happening now means I am out of luck. GM prides itself on durability and the "legacy" of owning a Chevy like my great grandad, my papa, and my father but that is just really just a way to sell more vehicles. GM won't stand behind this problem and it is potentially deadly. So my 2004 Chevy Tahoe sits in my driveway and I walk my children to the store because my sporadic problem has now become to bad to do anything about and I cannot fix it because no one (including the GM dealer) knows the real problem. Throttle body, throttle body harness, cruise control??? Who the heck knows. For now we walk. Thanks GM!!

    Hi lalaleeza,

    Thank you for providing a few additional details. I'm sorry to hear that you feel this way, and certainly understand your dissatisfaction with this situation. If you are still interested in having this repaired at the dealership, I would be happy to locate another dealership in your area and stay involved throughout the repair process.

    Amber N. GM Customer Care

  • The cost is outrageous. I cannot afford to go to another dealership so they can tell me that they do not know exactly what the problem is. As I stated before. There are so many "potential" parts it "could be". I made an appointment. I had a diagnostic and was told that there was nothing wrong. I drive away irritated that I just paid to have someone basically tell me I had no problems and 15 minutes into my drive going 65 mph in the highway home BAM! There goes the problem reducing my speed from 65 to 4!! I don't understand how GM can know there is an issue and just turn a blind eye?!! Must be nice to be selling vehicles for millions in profit every year but when is owners have a problem, there is no explanation and no help. Your welcome GM EXECS for paying your salaries!! While I set my car in the driveway and walk, you go out to your fancy parking spot with your name on it and get into your new car and drive away without the worry of having a potentially deadly crash or accident with children in the car. Until I can actually afford to fix my car or buy a new one, it sits and we walk. By the way, walking is awesome fun in the winter with 3 little boys but thanks!!
  • I heard on the news this morning that GM has a recall out now for a faulty ignition switch,, call your local dealers people. Not sure if this is related to OUR problem, but worth a shot.
