We look forward to hearing from you,

Did you get my e-mail? I have not heard back from you?
Day 13 without my vehicle!
In any case the dealer had their top mechanic drive it home for two days after I experience the issue again, after they "fixed" it.... The first day nothing happened the second day it did exactly what everyone is talking about in these threads. Reduced Engine Capacity and no power! He had he vehicle towed to the dealership and he told the service rep that I am speaking with that is was "Scary". So they now know what is going on. They continued to work on it today which they said they happened to have a specialist in from GM today and he will be looking at it as well. I provided them the link to this website so that they can show the specialist and learn more from this site. Hopefully it will be escalated, as you know this is a dangerous situation. Please let us know IF you hear back from someone.
Good luck with your issue. I feel your pain and frustration!
The way we have it worked out on my end is that I am out in the forums, looking for ways we can engage with our customers, and another agent Christina responds to the incoming emails. I will be sure to follow up with her today to see if she has received your email - she is coming in at 2:30 EST.
Thanks,

I feel your pain! Were any repairs done under warranty? Your best bet would be to become an informed consumer. Look up what constitutes a lemon in your state. If you live in Texas, it is the hardest state to get anything out of the lemon law. If you live in California, your chances are better. Unfortunately with my experience with GMC Customer Service, it's a waste of your time! They have it all worked out. I went as high as the corporate office and they just referred me to the legal department who of course have it all figured out. If you look at the Chevy Volt and the fire issues, NHTSA has been well aware of what has been going on. Did the government cover it up to protect their investment? Some in Congress are investigating the issue. Like I said in my previous posts, they have repaired all kind of parts, the throttle body included, now it is back in the shop because the accelerator has a mind if it's own and decides to lunge forward sometimes! The service department can't figure out what's wrong with it. I have gotten absolutely nowhere with GMC and had to get a lawyer. I am sure GMC will draw it out and take their sweet time! In the mean time I am driving around in a time bomb! I wish you the best of luck fighting for your consumer rights that GMC doesn't give a damn about!
BUT
The one thing I have noticed since getting it back is that I always had an issue with one of the running lights always burning out...guess what!! After wiring harness was replace it just started working with no changes to the bulb. So for all you out there and I see it a lot with only one day time running light working, get the wiring harness checked before anything else goes wrong and more money to fix!!!!
Friday night, onmy way home from work at about 5:30 my car drove almost the entire way home and suddenly started running rough like it was running out of gas (I have ran it out of gas before, and that is how I know how it acts) here's the fun part...my dash stopped working a week ago...flashing all of the lights and then all of the gauges do not work..just the lights with no warning lights on..... I have had the REP come on only in a parking lot...and if I turned the car off...and on again..it would start up and drive fine! Since I have no dash...I do not know if the REP message being displayed....funny thing is the check engine light does come on...go figure!
I have a 2003 Denali XL with about 150k on it.
I have never had issues with this vehicle.
So, had to call a flatbed to come and take me and the car home. I was at the bottom of a hill and would not have attempted to limp home. Calling this reduced engine power is a joke. How about no engine power?
Now, reading all of these posts...I am depressed...I cannot afford to throw money at this car. I have been laid off. Recently got a job that is 23 miles away. I live 6 miles from town. So catching the bus is not optional.
Replaced the fuel filter....but I need to know if your vehicles are starrting, but not running?
My husband is a mechanic turned fireman and also works 23 miles away...he is stumped...we are going to have it towed to the nearest gm dealership...10 miles away.....i
Anyone know if the dash and the REP could be related? I know it sounds stupid...but had to ask...
Husband swears it has to be fuel pump related....the pump is running...but the car will start, run normal, shutter and die....then you can start it, runs like crap and dies...then you can try to start it and it won't do a thing...it does turn over....
Any info would be appreciated! As my vehicle is about to go to the dealership and my pocketbook cannot afford it...
Yes, I am aware of the piston issue. It seems they made the pistons short on the AFM 5.3l engines. Oil gets trapped and clogs the pistons. The problem is that I have been telling them that I have a oil consuption issue and they tell me it's normal. They are just now doing an oil consumption test. I just don't think my truck is going to make it another 1k miles until they can check it! They have all ready replaced some engine parts when they broke at I think 36k miles. My biggest fear is that they keep replacing parts as they brake because the engine has a major design flaw. I hope that they just didn't replace the parts because it will happen again- just a matter of time. People don't see the oil consumption issue unit around 20k miles. It takes a while for it to build back up. Maybe they did something new to your truck. Hopefully they really fixed it, instead of throwing a bandaid on the problem. Thanks for the input! I'll let you know what they replace. I will be sure to ask if the parts are the same or if they changed something. Thanks again!
As far as my story, no they have not been covered under warranty thus far(I have 111K miles and it is a 2003). Here is the latest:
Day 20...
I heard back from the dealer last Friday, who have been great through all this. After working with the specialist from GM, they decided to replace the computer all togther. They have driven it all weekend with no issue but want to give it another day.
I rec'd a call from GMC Customer Assistance today responding to my certified letter. Who took my information and asked about the history of this issue and what was done at the dealers. They gave me a Case Reference # and said they are escalating it to a GM District Specialist for reivew. The GMC Customer Assistance Rep contacted the dealership as well. I asked what GM is doing about this but the rep did not have an answer at this time. I pushed the fact this is a nation wide issue and it is more a consumer saftey issue at this point and I don't feel safe to even drive this if it is in fact fixed.
The funny thing is my wife and I were looking to get a Cadillac but it is GM!
So I am hoping that may be resolved, however, what is my next step? Lexus/Foreign?
Let us know if anyone has been contacted by a GM District Specialist and if it helped in any way!
I really believe that the 2007's have more problems than any other year, although all gmc's between 2003-2011 seem to have that "reduced engine power" problem. In the 2007's the culprit is the 5.3L active fuel management engine block. Are you having oil consumption issues also? I think that they have to rectify the problem in order to pass emissions so they may have a longer warranty depending on the state you live in. California has the strongest emission standards. I printed out the blog on this issue, like 30 pages, on "GMinsidenews.com" for the service department and they looked at me like I was crazy! He said that you can't believe everything you read. It is interesting to see the development of this problem over the years and what GM has been telling its consumers. First it's normal, then let's put on a deflector, and then now lets change the pistons and add lifters. Not all 5.3L engines are doing this, we must be part of the lucky ones. There are enough of us though to warrant a "this isn't normal" claim. I have been a total guinea pig for all of the bandaids. Even though you are out of warranty, there has to be something they can do. Have you talked to the service manager and asked him to call GMC on your behalf? It would be really nice if someone from GM would actually back their product and notice that these problems can be life threatening. I now that GM watches these posts and it would be really nice if they could do something instead of saying, "I'm sorry for your inconvenience!" Is there anyone out there listening to us?
I went all the way to the district specialist and they did absolutely nothing for me. I was hoping that they could, but at this point I really think that short of replacing the engine, there is nothing they can do. Can you imagine if they conceded to the fact that there is a major problem, all the engines that would have to be replaced! They are just not going to do it. The best thing to do would be to get your paper work in order. Do you have a claim under the "lemon law" in your state. I waited and waited for them to do something and just wasted my time. The customer reps were so nice and you really think, hey they do care. But they are saying what they have been trained to say. Become an informed consumer and look into your options. It doesn't matter that you are out of warranty now, it matters when the problem first started and how many times you tried to have it fixed, even if you took your truck in and they did nothing, it may count as an attempt to fix. Good luck!
Here is my update - Day 23 without vehicle
The dealership replaced the CPU in the car last Friday. ($905.00) drove it all weekend and it ran fine. I went to pick it up on Tuesday, I got to the dealership and they were detailing the car for me and the Check Engine light came on again. They decided to keep the car until they feel it is 100% fixed, which they don't at the moment! They are having the GM specialist look at it again today. Not Good!
I heard from the GMC District Specialist...he stated he has been in contact with the dealer and they are working to repair the issue. He mentioned something about compensation, but typically vehicles over 100K do not get any. I commented on my concern about the safety issue and this site, which I didn't get much of a response. He said he will continue to work with the dealer and let me know the outcome.
As previously mentioned, my wife and I were looking at the SRX. I was speaking with someone at work and he showed me on this site too... SAME ISSUE! Not good for GM!
I will keep you guys posted!
What is your status with the attorneys?
Do you know what it takes to get a Class Action Lawsuit started?
At least then we would be a nuisance and GM might start looking into the issue
He said as long as the light goes away, I shud be ok. The engine light continued to come on and go off after a couple days. And, I started getting "Service Stabilitrak" messages that usually went away if I turned my car off.
Well one day I received some information that made me feel a little better. I was informed that I still was within my 100,000/5yr powertrain warranty, just barely. I took it straight to the dealership where I bought it. Its been in the shop for bout 5 days now. The service guy called me today to update me. He said one of my lifters was sticking which caused damage to the cam. Basically they are replacing the whole top portion of my engine: Heads, Lifters etc.. He also said they are installing the "updated intake manifold."
So far they have been good to me, I just hope the new parts fix the problem. I still owe bout $17,000 on Yukon so I dont want to feel as tho I am wasting my money...

stay tuned!
So, I took my Yukon to the dealership where I bought it. The mechanic had it for bout one hour. He told me that he was hearing a lot of noise from my #2 lifter. He also received several other codes which is on the paperwork.
Here is a brief summary of what the technician's notes on the paperwork.
"Scanned unit and retrieved trouble codes P0121, P0300, P0455, and P0449. Checked ignition, found ok. Injector test ok. Plugs ok. Compression cylinder #2 and #6 ok. Performed cylinder leak down test. #2 cylinder has 20% leakage. #6 has 10% leakage. Vehicle has excessive lifter noise at 600-2000 rpms. Scanned unit and retrieved code P0455 and P0449. Found reflash available for both codes. Performed reflash to ECM. SPS #11AAE. Removed Cylinder heads and found lifter #7stuck. Removed cam and found scored. Removed VLOM and found bad cam lobe. Found exhaust bolt frozen, removed per bulletin #2562850. Installed new lifters, cam, VLOM, lifter guides, reassembled, changed oil two times, roadtested ok."
Wow, alot of info I know. And the crazy thing is, I did not even notice a difference with my vehicle's performance. The only thing that I can say now that its fixed is it seems for responsive when i get on the freeway etc...one thing i told the mechanic when i dropped it off was that my vehicle doesnt seem to have that gideeup it once had.
The service manager told me that this has been a common issue. He also told me that they installed the "updated intake manifold." Now the new parts have a 27,000 mile warranty. Also, as long as you take your vehicle in to be diagnosed during the warranty, you will still be covered after the warranty miles if the issue returns or was not fixed.
All in all I have spent roughly $2600 on it and it appears that we may have solved the issue! Hopefully for good!
The dealer replaced the main computer, throttle body connectors, re-replace the TAC module, move some ground wires that the previous dealer originally moved and replaced the ignition switch.
I have to say the dealership has been great, besides a few minor messy things... however, they really cared about fixing the issue.
In the mean time I have spoken with the District Specialist from GMC who tells me there is nothing they can do to compensate me for these repairs as the vehicle is over 100K miles, but will help me get the best price on my next GM vehicle.... I asked if this website or the issue has been escalated to GM's management but never really got an answer.
I suggest we keep on this as we have mentioned before, this in my eyes is a public safety issue and it needs to be addressed before someone is in seriously injured or killed. I hope it doesn't come down to that to make GM open their eyes!
I will keep you up to date as to the "repairs" and let you know if there are any further issues.
Keep us posted if there is any Class Action Lawsuit or anything we can do to escalate this further.
I have a 2007 Gmc Yukon too that they fixed under warranty just before it expired. It is good that you have an open mind, but just remember that once you are out of warranty all bets will be off. We are all appeased until we have to start paying for the repairs! These trucks have a major flaw with their aluminum block engines that GMC is well aware of. The trucks engines are just not built to get more than 60k miles without issues. Some people are very lucky and don't have many issues, but the ones that do beware. They will have chronic issues. They have been doing a lot of bandaid work to these trucks to keep people happy while they are under warranty. I have been following different blogs- chevytalk, edmunds, gminsidenews. The AFM may be the culprit. Oil splashes on the cylinders causing buildup. It is nice that you feel for Sarah at GM, but you have to remember when an employee is stuck between the manufacturer who is being deliberately deceitful and the consumer who IS getting ripped off, there is going to be backlash. Gmc trains their reps very well to handle unhappy customers - with a lot of I understands and let me try to help- but they really can't help you because GM doesn't want to pour money into your problem. Like I said beware. Because you still owe money on this truck, I would just not count on this being a long lasting truck. The fixes are just temporary because the cause has not been addressed. Maybe I am a little cynical because every time I walk away from the dealership they told me that it was really fixed and I shouldn't have anymore problems, but it was just a matter of time. I really wish you the best of luck - just be careful!
Our'09 acted up for the first time on the way to church today... 75K miles, was 15 degrees and was in single digits through the night.
Traction control light came on first then almost immediately the low engine power light. Luckily we were only on a downhill grade at about 25 mph. Pulled over, turned truck off, restarted and problem persisted. Crawled with the pedal to floor at 17 mph max, went to church (need help from any source) and it ran ok until we were pulling in the drive only 4-5 miles from church.
Wife had to work today. Made it about 10 highway miles before it acted up again.
Was going to purchase a new Silverado to replace my '99 with over 300K and have had only 1 major issue on it (tranny at 185,000). Might be time time to consider the Ford F-150. Breaks my heart, I bleed bowtie red given the reliability of my previous Chevys.
I'll check the wiring pins at the throttle body as it seems a common "fix" throughout this thread. Stay tuned. hope we (wife, 4 kids and myself) don't become an obituary before I can figure it all out.

Yah I may be a little over confident since I got my Yukon back. Like an idiot, I spent almost 7 months stressing about my check engine light issues because I assumed my vehicle wasn't under warranty anymore. I think I'm more excited about not having to pay for the work that was just done. But TRUST me, I'm just waiting for the day that the light comes back on. In fact, 2 days ago I received "tighten gas cap" message twice in one day. And it was very tight so I'm not sure why it went off. Have you heard anything about the dealerships replacing the intake manifolds? I heard they were using a plastic material which obviously did not last long. I know on the paperwork when I got my vehicle back, it said: Replace updated manifold per bulletin.
Hey I was going to ask you, there are a couple other issues that Ive read about and experienced with my Yukon. About a year and a half ago, I noticed excessive cracking on my dash about the gauge cluster and passenger air bag. Also, every now and again, usually at idle, I can feel and hear a "thump" type noise that comes from the front right area. Have you experienced anything like that?
One thing I learned after taking my Yukon in, is the traction control/stabilitrak lights will come on no matter what the problem is. Im trying to think of the word they used but Im drawing a blank....anyway, it usually doesnt mean there is a problem with that particular system. It just goes off by default. Anyway, have you taken it in since posting?
You really need to protect yourself and look into the lemon law requirements in your state. I was outside the window to have the case arbitrated through the BBB - 6 months from your warranty expiring. GMC kept fixing my truck, even when it was out of warranty to string me along. Also, you need to look at the technical service bulletins on the NHTSA website before your warranty expires and take your car into the dealership. I have heard of the intake manifolds being replaced. The plastic material does not last because the engine gets to hot! There is one also, I believe, on the dash. Yes I have heard a thump, among other sounds because my truck has been in the shop so much. They have replaced quite a few things. If you hear a thump you should drop it off. In order to qualify for the lemon law, you need to have three attempts to fix the same problem. Even if you drive away because they didn't hear anything, it counts as a fix. Did you say that you have an oil consumption problem? How many miles are on your truck?
For example, she would take her Yukon to the GMC dealership where she bought it for an oil change. Less than two months later, she would get a "engine oil low" warning light. I thought it may have been a electric issue and like an idiot, I ignored it. I did get a little suspicious of the dealership so I photographed and marked the oil filter to make sure they were actually changing it.
I also noticed the her vehicle had the same "thump" noise. I am sure that if she kept it, we would be experiencing all the same issues. Somewhere in this forum someone said to check the VIN to find out where our vehicle was manufactured. Not sure if its a crazy coincidence but the 11th digit in my VIN is a R which indicates that it was manufactured in Arlington TX. My fiance's Yukon also had a R for the 11th digit.
The problem Im faced with now is, I need my vehicle to get around everyday. But if I drive it my warranty will expire in 2-4 weeks easy due to mileage.
I will look into the lemon law here in California. I will also research NHTSA's website.
What do you suggest I do? I paid a lot of money for my Yukon, and I still owe a lot. Like I said before, I am a little over excited with the recent repairs, but I am dreading the fact that the issue with come back right after my warranty expires.
How many miles did your Yukon have when you took it to the dealership. Did you receive any warning lights on the dash when it stopped? and does your Denali have the 6.2 or 5.3 engine?
Also, did the dealership diagnose the problem? I am fairly new to all this even though Ive been experiencing the problem for quite some time. And, I am in no way a mechanical expert. I'm not sure why they wont recall the problem, but my guess would be that it would be REALLY expensive for them. The cost to recall a problem is probably WAY more that to fix the problem on a individual basis.
Some peeps in this Forum like unsatisfied16 have had some major issues. And they have done some very valuable research.
I may be crazy, but sometimes I think this companies make products to last only last so long. I dont know what it is, but it seems like no matter what style cell phone I get, it only last so long and im forced to buy another one. Like i said, im prob just crazy LOL
One last thing, check the 11th digit in you VIN...just curious if it is a R like all the others having the same type of issues....
Regards,
Sarah

I'm having a similar problem with the throttle, but I just found out that the warranty expired last year in may. I purchased the truck in Feb 07. Now I see that this problem is coming from manufacture is there something we can do about it. The first signs of this problem was the check engine light and then the stabilitrack light came on with the engine duce. plz what is it that I can do about it .
GM does warranty replacement parts, but the duration of the warranty depends on the nature of the part. Generally, there is a 12 month/12,000 mile warranty that will extend past the standard issue warranties (i.e. powertrain warranty); on powertrain items (say a vehicle needs a whole engine replaced), the replacement part warranty is much longer (3 years/100,000 miles for an engine).
Best,
Sarah

My 2007 Yukon XL is back in the shop again! Last year the throttle body was replaced on a Monday and it was back at the dealer on Wednesday with a rough engine and engine light, stabilitrak and traction control OFF.
They said that it was completely unrelated to the previous work. They did a complete tune up (replaced plugs, wiring, etc). Still got the intermittant engine light with stabilitrak off, traction control off, but it reset.
Guess what it has now...a misfire when idling and they are telling me I need to get a complete tune up AGAIN and get the throttle body cleaned.
Hard to believe!!
GM did tell me to keep the receipts in case of a RECALL.....still waiting
Your dealer was correct, the throttle body was eliminated from powertrain coverage as of the year 2010. Other items that were eliminated from coverage include: the entire pressurized fuel system (in-tank fuel pump, lines, fuel rail, injectors and return line, the engine/powertrain control module (ECM/PCM) and module programming, the transmission control module (TCM), transfer case control module and module programming, clutch and pressure plate for manual transmission, sealed wheel bearing assemblies or hub and bearing assemblies (axle shafts, seals and bearings that are part of complete axle housings are still covered).
At the same time, there have been additions to the Powertrain portion of the coverage for 2010, including:
Engine oiling system including the hoses, lines and cooler.
Crankshaft Pulley.
Clutch Master Cylinder.
If we can be of any assistance in working with your dealership, please don't hesitate to get in touch via email.

But what really gets me is that for this seemingly unnecessary, dangerous addition to my vehicle, I dont really need it. But you cannot 'get rid of it' therefore you have to have it serviced when the crap shuts down a normal operating vehicle.
Sighn me up; I would be glad to share my experiences in ANY lawsuit against these people; because it is DANGEROUS, and put many drivers in harms way; not just us, but other drivers that have to compensate because our engines were shut down UNNECESSARILY by a stabilitrak system while driving full speed on the freeway.
GM and this stabilitrak system need to held accountable; they are putting people into a dangerous condition on the freeways.
Hope it was wirth it for them... but it may not be that simple if enough people experience engine shutdowns on the freeway that causes a collision an d they get their ASSES sued.
