Check engine light is on. Vehicle is showing a P0008 code with 92,000 miles this is a crankshaft misalignment that I was told means the timing chain will need to be replaced. This is apparently a widespread issue amongst GMC Acadia owners.

My timing chain was replaced under warranty 4 year and 50,000 miles ago. Now I am having to replace it again. I contact GMC about recall10287 premature chain wear for reprogramming of the engine control module. I was told this does not apply to my year and there was no part listed because it just a general statement. Not sure where to go from here. Here is my case # for GMC 8-4704107640. I am still awaiting the part information from them.

This has happened about ten times now all within the past 3-4 months. I will be driving and go to make a turn and the steering wheel locks up and the engine dies. The brakes still work so I am able to stop the car, turn they key off and restart it. It had happened to me once on the highway and the rest of the times have been stop and go turns in the city but once was while turning left onto on cmong traffic and my car died in the middle of it. I took it to 3 different auto places and all told me they couldn't find the problem. I then researched this and found several other people having this same problem. I contacted them and they set me up with a dealership to get it fixed. GMC said if it was under 150,000 miles they would pay for it and if it was over then I would still qualify for a payment assistance program. However a day after dropping off my car to get fixed the dealership called me and said they don't know how to fix my car and to come get it out of their parking lot. We told GMC about this and they said it's not there problem. I'm at a loss at this point as no one seems to be able to fix the car and it is a death trap for me and my family. I'm also not just going to sell to the car to somebody like the dealership advised me to do because 'they wouldn't want their son or daughter driving that thing' (even though they seem perfectly fine to have me drive it off their lot asap and not be their problem anymore) because I wouldnt feel right selling a car to someone knowing it could kill them through no fault of their own. I don't know what to do here. The right thing to do would be to put that car in the junkyard and buy a new one but I don't have the cash. Would like somebody to tell me how to fix this.

The timing chain needs to be replaced on the 2010, which is the same issue GMC had with the 2009S, however, the 2010 isn't covered, but the 2009 was. I've read that GMC knows that there is an issue, but they just aren't covering it yet.

- La Grange, IL, USA

Timing chain needs to be replaces and isn't covered although it's the same parts as the 2009 model that is covered by the extended warranty. GMC is aware of this ongoing issue and should cover

- Bay Village, OH, USA

The contact owns a 2010 GMC Acadia. While driving 45 mph, the throttle malfunctioned and the vehicle accelerated rapidly without warning on more than one occasion. The contact stated that the vehicle accelerated to 95 mph. The contact was able to slow the vehicle down by depressing the brake pedal with both feet. Bessette motors in carrington, North Dakota was made aware of the failure and replaced the throttle body, but the failure recurred. In addition, the pedal positioning sensor was replaced. The manufacturer was made aware of the failure. The failure mileage was approximately 85,000. The VIN was not available.

- Sykeston, ND, USA

At $60,000 thousand miles my timing chains needed replaced (just like the 2009 which has a recall) then at 79,000 miles my wave plate cracked on my transmission (which there is a recall on the 2009 model for the exact same thing) my car was a early 2010 model and it looks like the 2009 issues are problems on my car. I think it's insane that GM can't stand behind their work better than this. The recall's should cover the 2010 models that were manufactured with 2009 parts!!!

- Greenville, SC, USA

Timing chain needed replacement due to stretch and check engine light at 137,882 which cost $2,049. This issue was covered under special warranty for 2007-2009 model years, but the 2010 is not covered. My understanding of GMC's fix is that nothing changed with the timing chain and the oil system life was lowered as to when an oil change was recommended by the vehicle (more frequent oil changes). I have completed all scheduled oil changes based on the automated prompt from the vehicle and still had to complete this costly repair out of pocket. I would like to see this known issue also covered by the special warranty on newer vehicles and be reimbursed for my expenses.

- Auburn, MI, USA

The contact owns a 2010 GMC Acadia. The contact was in the process of trading in the vehicle. While driving approximately 15 mph, the vehicle suddenly stalled. The contact had the vehicle towed. A certified mechanic diagnosed that the motor burned an excessive amount of oil, which caused the failure. The vehicle was inoperable. The vehicle was not repaired. The manufacturer was made aware of the failure and informed the contact that the repair was not covered. The approximate failure mileage was 106,000.

- Barre, MA, USA

Car has been serviced regularly. Engine was running smooth. Drove approximately 30 miles on hwy to work got off on city street and car started shaking bad. Pulled over into parking spot and engine cut off. Wouldn't restart. Called towing to our repairshop. The first cylinder spark plug was bent resulting in major engine failure due to timing belt stretch. Need a new engine and found that this is big problem with GMC engines. Bought the car less than a year ago and it currently has 138K miles. 7K to replace engine including labor. Wow mother of 3 kids and I'm still paying big payment for the car and insurance.. so many complaints about this issue I just found out with GMC covering the issue up and not being responsible

- West Blocton, AL, USA

The contact owns a 2010 GMC Acadia. When the heat or air conditioning system was activated, a fuel odor emitted inside the vehicle. The dealer diagnosed that the HVAC system failed and needed a filter installed. The vehicle was repaired, but the failure recurred. The manufacturer was notified of the failure. The failure mileage was 47,125.

While I was driving tonight my vehicle shut off in mid turn causing loss of power steering. Where this happened is a very busy intersection. I had to pull over and when I put the car in park and restarted it came on for a second then shut off again. Then was able to get it running again. I had my wife and 6 month old daughter in the car and this could have been a very different outcome. I have read many of complaints online about this same problem in these vehicles. I really feel that GM needs to take a serious look at this issue before something major happens.

- Millstadt, IL, USA

Without any warning, car died while driving. Timing chain apparently stretched after only 39,000 miles. This is the second timing chain I have to replace. GMC has extended the warranty for several models to 120,000 but not my year!

- Amherst, NH, USA

Timing chains stretch. Very common issue on this and other GM vehicles with 3.6L engine. Just purchased my vehicle and it's at the dealer for a $2600 repaor on this problem. Can happen at any mileage and without warning other than check engine light. Timing chains stretch causing engine to be out of sync and eventually engine damage/failure while driving. Minimum cost of repair is $2500+ as engine has to be removed to do the repair. GM has knowledge of the problem and even issued extended special warranties to cover the problem on 2007-2009 models only even though 2010 and newer models have same problem with same engine. Any internet search will yield hundreds of other owners with same issue.

- Jacksonville, FL, USA

The contact owns a 2010 GMC Acadia. While driving 45 mph, the check engine warning indicator illuminated. The vehicle was taken to an independent mechanic where it was diagnosed that the timing chain and crankshaft needed replacement. The vehicle was not repaired. The manufacturer was not made aware of the issue. The VIN was invalid. The failure mileage was 84,823.

- Glenside, PA, USA

I'm filing a complaint about my model year 2010 GMC Acadia. My check engine light has come on at 96,000. The code is P0008. This code points to the timing chain. This is a known issue with GMC Acadia's and is the same issue that caused GMC to extend their powertrain warranty on 2009 model Acadia's to 120,000 mile or 10 years. GMC is not offering to extend my warranty to 120,000 miles or 10 years even though I'm experiencing the same problem that caused them to extend 2009 model cars. My car was manufactured in Oct 2009.

- Wake Forest, NC, USA

Check engine light came on and I took the vehicle to the local dealership. The service representative informed me this was a stretched timing chain issue - a common issue with GMC Acadias. Upon searching the internet for error code P0008 it pulls up loads of information regarding the Acadia timing chain issue. In fact, model years 2007 through 2009 had an extended warranty issued for them up to 120,000 miles for this exact same issue. My vehicle is a 2010 and is experiencing the same issue that was recalled, and my vehicle was most likely manufactured during the time they were experiencing timing chain issues. My timing chain failed at only 71,000 miles, well below the recommended timeline. I called GMC to file a claim and see if they would cover this under some warranty. I was told by the representative that they were aware of these problems but since I purchased the vehicle used, there was nothing they would do for me. I have performed all maintenance on the vehicle at the recommended intervals and still experienced a failure. This was an extremely expensive fix that was unacceptable since it should not have happened in the first place. GMC should stand by their products when they are aware of issues like this.

- Spokane, WA, USA

The contact owns a 2010 GMC Acadia. While driving various speeds, the vehicle stalled and the check engine warning indicator illuminated. The vehicle was able to restart on the third attempt; however, the failure recurred. The vehicle was taken to the dealer where it was determined that the timing chain fractured and needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The VIN was unknown. The failure mileage was approximately 91,000.

My wife's GMC Acadia shut down while driving down expressway and lost all power and threw a cel. The diagnosis from the dealer mechanics was a stretched timing chain. I was told this is common and a scheduled maintenance part but nowhere in my manual does it state this. Also I contacted GM corporate to see if I could get help it being a safety issue for the shut down and was told it was out of warranty and there was nothing they could do. My vehicle has approximately 149,000 miles now I have to pay over $2000 to fix a known issue but the real problem was the unexpected shutdown and loss of control in the middle of rush hour traffic in a rain storm. Fortunately my wife's quick thinking got her to safety but could have been much worse if she would have lost power in the middle of a busy intersection or an on ramp she could have been severely injured. I would like to see these problems resolved.
