I was just waking up when I heard this so some Information may not be accurate. But I DID hear them talking about how GM cars from I think 2004 up have been having issues with the engine cutting out while driving,, caused over 70 deaths, blah, blah, blah,, hopefully they figured out what the issue is and hopefully my car will be fixed. My anxiety has been so out of control having to drive this car on the highway for work everyday,, wondering when I am going to get killed. It happened again the other day, during a bad snow storm,, yup,, that was AWSOME,,, GM,, you suck!! Never again,,
I just checked and of course my Impala is not included in the recall,, unfair!!! GM,, you suck!! Going to trade y car,, never will I buy another GM product again,,,
If you have any questions regarding any open recalls on your vehicles, please feel free to send us an email to firstname.lastname@example.org with your VIN included. We will be glad to look into this for you!
GM Customer Care
I've already done that and it was useless. GM claims to not have had any complaints on this,,, useless!! I was told to call the national whatever it is to file a complaint,, did that and low and behold,, their system was down so they couldn't enter my complaint in,, sickening,,, just sickening. My lawyer is going to love this!!!
The worst winter in Chicago was also the worst winter with our 2004 Yukon Denali - after babying the beast for years, I have had it. The Check Engine light is on continually, the Reduced Power due to the Stability Control occurred Friday evening on the I94 with 4 kids in the car - almost gave me a heart attack. I read the posts from 06 and will bring to a reputable mechanic to check with Wiring Plugs on the Throttle Body, Front Abs Sensors. I was trying to get another 2 years out of the Yukon - but at this point, I will sell it for parts and buy a Ford. Between this and the Brake Lines snapping last summer - I am done. You would think GMC would be forthright on what people are reporting as "potential problems" and what they suggest as preventative measures that should be taken especially with late model vehicles. My truck wears with honor the badges of the places we have visited - ski trips, family vacations, road trips hauling the boat. This is leaving a nasty taste in my mouth and I am looking at other trucks instead of going back to the one I have enjoyed for so many years. 2 Potential Life threatening incidents in one year is a tough pill to swallow.
'09 Yukon XL Denalli I too had this exact same problem as so many have mentioned. At first the "On Star" lady put me on the line with a GM Tech. They sent a tow truck , once at the Dealer I got a loaner truck . On Star Tech told me Throdle Body Housing and wiring , Dealer said the same thing, but gave me the not covered runaround. I walked over to the Ser. Mng. told him I had the extended Warranty and I DO NOT need this type of run around . I was advised to take the Truck and would be called the next day ? Strange I thought ? But to his word he called said it would take a week for parts ect. and I have a 100 deductible. I can live with that , so I looked up what was going on in this site and was SHOCKED . I feel lucky as Hell I am going to file with the NHTSA but thanking my lucky stars it didn't happen on one of the super busy Hwy. here around ATL. Yes I got it back in 7 days and charged $100.00
GM has known for years about the problems with these engines, but unless you bought your car after the bailout then GM doesn't have to do anything. It is the owners loss. Even after the bailout GM will most likely never do anything about the issues for the people who were unfortunate enough to purchase a GM truck. GM will not stand behind its products only its profits....same with the dealers.
Sorry this site will not let meEdit my post. I want everyone to have the correct Info. this is a 2009 Youkon XL Denalli with 77,000mls when this problem happened.
@squekie, I edited your post to change the date.
So, I assume the dealer got the parts in for you by now. Any more issues?
Moderator - Buying questions? Please include selling price (not OTD), zip code and trim you are shopping.
I have to say that my 2002 Denali just did the same power lost thing you guys are talking about. You all helped me fix the problem free. I just got back from Charleston SC and now know why I had the problem. The roads are like a washboard and loosened my battery cable or cables. I tightened the cables, started the truck and has been fine for 2 days. Make sure you buy a side post battery wrench or you will never get the cables tight......Thanks again I isAL
I have a 07 yukon xl and this just happened to my wife(loss of power and service stabilitrack). I checked on you tube for a fix and got several, looks like it may be faulty wiring on the throttle body.
05suburbannn said:For a year now, my 05 Suburban has been going into reduced engine power mode. I have done the grounds, the wiring and new pigtail for the throttle position sensor, the entire throttle body, new gas pedal/sensor AND the throttle actuator control module (computer on the driver side firewall). I have even done a thermostat. I still have the problem. The only win so far is that I have done the work instead of paying the dealer MASS$ to be in the same boat. ANY OTHER SUGGESTIONS?

I purchased my 2006 Yukon last September 2005. I now have 24,000 miles on it. Over the last month I have had it into the dealer three times for the same problem. The problem is that while driving the vehicle it will suddenly lose almost all power. The Information Center will display the messages: "Stability Control Disabled", "Engine Power Reduced". And the vehicle will not go over 20 mph on a level surface and bearly 3 mph up a moderately steep hill. Each time I have had it into the dealer for repair they have beeen stumped by what the cause of the problem is. They said that GM/GMC told them that "GM is aware of the problem but does not have a fix for it at this time". How can a manufacturer sell a vehicle that has a defect and not have a fix for it? When the power goes out in a busy intersection or on a highway this is a major safety issue. Has anyone else experienced this problem.
