general problems of the 2009 GMC Acadia - part 1

There was a recall for GMC premature timing chain engine recall. This recall was complete in 2011 but it did not fix the problem. The timing chain keeps breaking off the cam shaft sensor and needs to be replaced.

The stabilizer/traction control keeps going off and it will stay off. I can turn,hit a bump or start it up and the traction control/stabilizer system is off. I almost had a accident on the freeway in the rain because it turned off out of nowhere and I almost lost control. Also I was going down the road and all of a sudden my vehicle died and I had little control over vehicle. Once it came to stop it would not start again and when attempting it sounded like something was stuck in my fan or something because of the way it rattled and sounded and was rough sounding. Vehicle was inoperable and had to be towed. Upon investigating it was the timing chain kit that had failed suddenly for no apparent reason. Vehicle was well maintained and kept accordance with running policies and practices required and suggested by manufacturer. Still the failing caused engine damage that is well in to the several thousands of dollars and engine must be replaced due to this issue failing and I have noticed several thousand people having this same very issue and rendering them a foot and vehicle less due to the high cost of fixing without any warning or engine light or code suggesting of the timing chain kit failing or about to fail before stranding a person wherever and whenever unexpectedly and suddenly without any warning or check engine light at all. No oem code to validate the issue either. Manufacturer should be held liable for the exact same issue occuring in so many of the multitude of people experiencing the same exact issue causing financial turmoil and risk of disaster or collision and harm when the timing chain kit fails suddenly. This is a huge and vast problem I have found with multitude of Acadia owners and should be addressed because to not honor a issue of so many experiencing the same issue occuring should be reconciled and corrected at the manufacturer cost due to it being their liability in making the faulty part of device to begin with causing vast financial hardships.

Got code po0008 crank sensor/cam did resurch said timming chain replaced complete chain still noisey changed cam phasers and sensors still making noise it is so frustrating bee going on 3 weeks I'm disabled not easy to work on myself being I'm a master technician and this has really been mind boggling.

The contact owns a 2009 GMC Acadia. The contact stated that after purchase of the vehicle, the vehicle lost motive power and stalled while driving at 45 mph. There was no warning light illuminated. Despite the failure, the contact was able to coast the vehicle to a stop as the vehicle failed to restart after multiple attempts. The contact's husband inspected the engine and had the vehicle towed to the residence. The contact's husband replaced the crank shaft position sensor, purge valve, high pressure tank, fuel pump, and battery; however, the failure persisted. The contact then towed the vehicle to an independent mechanic where it diagnosed with engine failure due to the timing chain, and a cylinder #1 and #5 defect. The manufacturer was notified of the failure and informed the contact that there were no recalls on the vehicle related to the engine. The vehicle remained in possession of the mechanic unrepaired. The failure mileage was 194,726.

Engine jumped out of time driving down the road.

1. )what component or system failed or malfunctioned, and is it available for inspection upon request? a. ) to start with I went in to the dealership for a timing chain recall they said the work was performed. This was never done all they did was replace ecu from an older car so that the code would not come back (replaced with a 2002 ecu) to get rid of the timing chain recall code. This code never existed in 2002. . Complete negligence these SUV could hurt or kill someone b. )huge electrical issue SUV stops on its own while driving. Sometimes does not start at all. Can not pass emission for the life of it . . New codes all the time I have replaced just about every sensor and switch there is. . . This is a money pit and death trap. . C. ) the investigation NHTSA should have included the lambda frame it's the same design flaw they're trying to fix one problem with an old problem. The ones on these have this fixed tie rods, lateral arms and upper control arms the bushings will wear out eventually and repeat the bouncing up and down rocking back and forth rear end barely staying on the ground it's a very dangerous ride and you see these vehicles on the expressway on a daily basis you look at them for what you know now I get really nervous seeing these vehicles. Arcadia rollovers call it what you will it's the same problem the needs a total redesign it's defective anyway you look at it. Just looking to how many roll over there are with this body frame and suspension it's got its own self-contained pit maneuver. I believe gm is aware of these issues that's why they're giving everybody a hard time to fix it they run and say something else. Looks like we're getting back to too big to fail. D. ) what makes this vehicle even more unsafe and very dangerous is the fact that the reluctor wheel can slip. This will sundown false dtc codes thinking that problems exist other places spending lots of money an unnecessary work when along gm knew about this problem once again.

I had to, replace the transmission. . Driving on city street car would not accelerate although rpm needle showed motor revving now waiting on stability control module thats on back order.

My 09 Acadia is having timing chain issues. Just about everyone of them does. Why is this not recalled?.

Tl the contact owns a 2009 GMC Acadia. The contact took the vehicle to an independent mechanic to have the timing chain replaced. While the mechanic was test driving the vehicle at 30 mph, the vehicle began to smoke. The mechanic pulled the vehicle over and determined that the vehicle "blew up". The vehicle was destroyed. A fire and a police report were filed. There were no injuries. The vehicle remained at the scene of the incident. The manufacturer and dealer were not notified of the failure. The cause of the failure was not determined. The failure mileage and VIN were unknown.

I've had electrical issues with the radio. Every single time it rains the speakers go out. Noticed there was water in the electrical connectors on all the doors which also affected my windows from going up and down. More importantly, the transmission is shot now. Was driving to the store, stopped at a stop light, and when it turned green, I hit the gas. My car didn't go. I kept my foot on the pedal with the same amount of pressure and it started to go, but after a few seconds it just kicked real hard into first gear. Felt like someone rear ended me. Every time I stopped it kept doing it. Took it to the mechanic and apparently I need a new transmission and timing chain. The car is only 10 years old and I bought the car 5 years ago from gunn Honda. This is ridiculous! constant problems with this car!.

Tl- the contact owns a 2009 GMC Acadia. The contact stated that the vehicle experienced loss of acceleration and power. The contact veered to the shoulder of the road and attempt to restart the vehicle which failed to start with all the warning lights illuminated. The vehicle was towed by a independent towing company to taken an independent mechanic at riverbend body shop 4141 lake michigan dr. Nw, grand rapids, mi 49534 (616) 453-7795 where the vehicle was diagnosed and determined that the timing chain failed and needed to be replaced. The vehicle was not repaired, however, the failure recurred. No dealer was contacted. The manufacturer was not notified of the failure. The failure mileage was approximately 138,000. Ck.

Bought the car on Feb. 28, 2018. Found out on January 23, 2019 that it needs a new engine. This is now the 2nd GMC Acadia we bought in less than two years that needs a new engine. That is not right. We have now spent over $20k for two cars we currently don't have a working car. The last car I bought was a 2010 GMC and I was driving the car on the highway and smoke started coming out of the engine. Later it was determined that the engined died - there was never ever warning lights or warning that there was trouble with the car. Both cars have the 3. 6l sidi vg engine. Our auto place said they are having a hard time finding that engine because many people need that engine for the exact same problem. Can not be a coincidence. I have contacted GMC and they don't care.

100% of everyone I have talked to that have had the same car as me have had the timing chain break. And the amplifier go out because of leaking through the door and frying the amplifier. So no sound in my car at all.

GMC has a special safety recall on their timing chains but provided no help when dealerships fail to notify you before the warranty is out even when you are complaining. When driving the vehicle refuses to move and the rpms just go up. GMC tells you to go back to the dealership that failed to find it to get your money back. Passenger front air bag turns on with little weight to no weigh there! mc danials in marion, ohio was able to find thatbthey lose calibration and need re calibrated.

Dec 2018 my Acadia was left at the service department of whitmore Chevrolet in west point va 23181 for a diagnosis. My vehicle ran when I left it there. Over a month later including illegal activity in the service department I get my vehicle back and it is dead. I would start my vehicle and drive away sometime stopping soon or randomly on the road. It's done that several times. I have three children too. I need my vehicle looked at and the possible recalls fixed. I am without transportation and it's unbearable. I am a mother of three wonderful sons and we need our vehicle to run please!!!my review is in the pictures as well.

P0017 and p0008 error codes: my wife loves her Acadia! dealership has done recalls, replaced rack and pinion and ps pump. I am close to positive that ecm has been modified to shorten oil change, to not define a chain potential failure that sends an error code, and update software to allow for more "slop" in clearance specs so that chain issues are concealed until a critical failure of equipment. At 121k I dropped cradle down to repair/replace wave plate. Plate was good as new. Must have gotten a "good" plate. Now at about 140k I have the p0017 and p0008 codes. Engine not responding accelerator wise as before. I am going back to dealer and ask to see service record of what was done to engine. I know I will just be wasting my time. To cover up a problem by messing with parameters on an engine to fool a customer is close to being dishonest, and that is what's happening with the chains. If all else fails at the dealership, and they send me away, I will park the Acadia in the garage and do my best to replace the chains and gears with the engine in vehicle. I have no way to drop the engine out. I can't afford $4000 for the dealership to do it. Gm, I have always been a loyal fan on your vehicles, and have only owned chevy's and GMC's since 1965, never owned any other brand, except a 1947 Jeep universal that I put a small block in, but this Acadia transmission/engine issue might just test our relationship in the future. What I have read on social media, these codes are popping up all over the place, and gm is not caring, even tho they now have a 10 yr/120,000 coverage. I am beginning to think that this issue will never be resolved in favor of the customer. Design problem and poor back valve cover venting. Gm, you can do the right thing here.

Tl the contact owns a 2009 GMC Acadia. While driving 55 mph, the check engine warning indicator illuminated and the vehicle misfired. The vehicle was taken to an independent mechanic who diagnosed that there was fluid inside the engine. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 151,000.

Engine will not shut down when key is removed and cruise control isn't working.

2009 GMC Acadia. Consumer writes in regards to loss of engine power, steering wheel power and faulty brakes. The consumer the liftgate and lamp were repaied under recall, but the failure continued. The consumer did not recieve notification for the recalls concerning the engine, transmission, and timing chain.

The 3. 6l engines have an issue with timing chains going bad, possibly breaking.

My car completely died while driving it a few months back. Just got it back after about 3 months, partial sucky dealership, partial back order issue. Turns out the sunroof leaked into the dash. Had to replace the body harness and something with the dash. $5100. I estimated on the date it happened because it's been awhile.

I have replaced two ignition coils and now have a third going out. When the car is under load it misses.

GMC knows of defective timing chains in this make and model. They addressed some of these issues in tsbs and the information was known by dealers but never conveyed to owners that did not receive a TSB. The dealership performed numerous oil changes, which if increased in frequency and more closely monitored, could have been part of the fix, but the dealership never informed the owner of potential catastrophic consequences of not increasing oil change frequency. According to dealer, gm forbids them from disclosing such information. These engines were also equipped with a pressed on crankshaft reluctor that could shift and result in a total crankshaft replacement. Failure of any of these vital engine parts alone or together while the vehicle was in motion could, I believe, cause an engine seizure which could potentially lead to devastating consequences. Non disclosure by dealers to alert owners who could then divest themselves of these vehicles before the 120k deadline set by gm is dishonest at best. No tsbs relating to this were received by owner. There is now an engine warning light concerning the timing chain and possible reluctor but gm is unwilling to assist with repairs since the vehicle is about 15k beyond their arbitrary 120k deadline.

I just entered the highway with an increased speed of 50 mph when the dashboard flashed. . . "engine power reduced. " my car was about to shut down in the middle of a very busy highway. I made it to the side of the stretch with cars almost hitting me to call a tow truck. The car was towed to gateway Buick GMC in st. Louis, missouri where the service worker informed me that I needed the following: valve element heater hose camshaft actuator thermostat mode door activator I then received a call back the next day stating that I needed a new engine. My car is under ten years old.

Transmission had a hard shift into reverse. Diagnosis was the 3-5-r wave plate and upon reading other complaints seems to be common. Transmission shop theory is that the wave plate was hardened too much and became brittle with the flexing causing it to break. Dealership fixed problem with warranty help from gm but still cost $750. 00. I believe that gm should have paid the entire amount since it was well under the 100,000 mile but we owned it for 6 years. Seems that this failure is a function of mileage and not time and thus should be totally covered.

2 months after I bought my vehicle used I have had to replace ignitions coils, so many recalls and only had some replaced cuz of being told they don't have the part in store at the dealerships. The electrical system for heat and a/c don't match up when turning the knob and the defrost doesn't work 3/4 of the times. I get flashes of loss power and my tire monitoring system keeps acting up. Now my engine and transmission are failing and no one can tell me exactly what it is without paying $5000 for them to diagnostic it and take it apart!! where do I have that kind of money?? this vehicle was the worst $16000 I have ever invested in and have only had it less that 2 years!! I am scared on a daily basis to drive my kids anywhere in it let alone myself to work. I so wish I would've kept my Jeep grand cherokee but we need more room for travel. Well you can't travel in something that's unsafe and unreliable. GMC won't call or respond back and either will the dealership. Lemon law in michigan is for new vehicles only so I am basically paying for something I can't drive and I can't afford to fix. What do I do??.

2009 GMC Acadia coil pack failures. The coil packs fail without warning causing a loss of power from the engine. It can occur at any time. We had 2 failures since June of 2014. Both times we were in traffic and this loss of power created unsafe driving situations.

Vehicle was exhibiting a miss under load at low rpm. Diagnosis was a bad coil on number 1 cylinder which was replaced along with the associated spark plug for approximately $300. 00.

Various gm vehicles have a known defect that allows water from the sun roof drain to enter the passenger compartment and more importantly allows water to enter the passenger compartment fuse block. This defect is covered under service bulletin #08-08-57-003c. This vehicle has had numerous electrical system issues that only occur during heavy rains and the dealer has been unable to recreate the problem after things have dried out so to speak. Most recently after a heavy rain, the battery was dead and when replaced with a new battery, the engine would not shut off even after the key was removed. This is a serious safety concern that can result in injury or death. The only way to shut off the engine is to remove the ecm fuse from the under hood fuse block. Not being able to shut the engine off via the key can have serious life consequences in the event of an emergency. This is a wide spread issue that seems to get worse over time and ends up with not being able to shut the engine off. The gm models affected by the service bulletin as follows: 2008-2012 Buick enclave 2007-2012 GMC Acadia 2007-2010 Saturn outlook.

I bought my GMC Acadia, used with approx 50,000 miles on it and have owned it for less than 4 months and with in the last month have replaced 3 ignition coils and I am assuming will have to replace more. From my understanding there is no issue that is causing the coils to fail other than the part is going bad. And what I was informed is that GMC is now using a different type of ignition coil which would lead me to assuming that the ignition coils they put in the Acadias are faulty. And now the owners are left to foot the bill, which does not seem right. The tough part of my situation is that I purchased this GMC after trading in my pontiac gto that was in the shop for 10 months while gm sat around doing nothing for me. All 5 vehicles that I have owned were gm vehicles and needless to say now, I will not be purchasing a gm vehicle ever again. Gm customer service is the main reason for this. I understand that these thing happen but gm should make the situation right and have not even come close to making me feel valued as a customer.

Initially noticed when shifting from park to another gear shifting was hard. About a week later noticed hesitation in shifting gears while driving at various rates of speed then the engine would rev once it shifted into gear. Eventually parked the car in drive then went to back out to take to dealership and it would not go into reverse. Vehicle towed to dealership where they replaced the wave plate and other parts that were contaminated. Since this incident the vehicle has not drove smoothly or shifted gears smoothly. It also gets less than 15 miles to the gallon during my daily commute now where prior to the transmission fix I would get 19-20. Vehicle hesitates and revs continually while driving and accelerating. When I returned the vehicle to the dealership stating there was still an issue I received "we could not replicate the issue" and sent on my way. After research on this site and other and reading the systemic issues others have had just like it I am concerned for my family and those around me safety if the transmission decides to stop while traveling high speed in traffic or when crossing traffic.

The car felt as though the gears weren't catching and rpm would drop but if you took your foot off the accelerator it would go away for a second but then it would happen again. No one seems to know what's wrong, but it seems as though the transmission is slipping. It seems to happen at speeds of 50 miles and higher which is very dangerous especially when traveling on the expressways.

In slowing at manual stop sign, the engine accelerated (while I had my foot on the brake) to a very high revolution--approximately 4,000 to 4,500 revs--and I had to put all of my leg strength into pushing the brake pedal to the floor, while I hurried to shut the engine off. Once I had turned the ignition off, the engine did shut down the way it should have. Once that was accomplished, I started the engine up again and it ran without any further incident. It was a few months later before another such incident occurred. The second time this same type of situation occurred under virtually identical circumstances, I took the vehicle into pat mcgrath GMC's service department and explained what had happened. The service manager immediately drove the care to test it, but naturally the car didn't act up. At that point they attached a monitor to it and told me to drive it until the problem recurred, but after a week of no such problem occurring, I had them remove the monitor ironically, the problem occurred under exactly the same circumstances the next morning. So far I have had this same experience recur approximately 6-7 times as I have been slowing down to stop the vehicle, the engine would rev up badly, but I already had the brake on to stop it, put it into neutral and shut it off. On restarting it did so properly and there was a time lag between problems. GMC is now aware of the problem as I had posted it on the Acadiaform. Net. At they point they had had no other such issues brought to their attention. . .

Starting in winter, 2013, cylinder engine coils corroded, replacing #5, then #2 11/20/14, then #1 2/24/15, then #1 again 3/31/16, at which time #1 was full of water. 10/6/ parking brake alarm comes and alarms constantly with raining or after a rain . Car mostly garage kept, so a delay in symptoms compared to blogs. Sunroof,wind shield ,parking brake no leaks found. Cyl 1,3,5 misfire codes& cat replaced. 2/2/cat code again, not repaired. Sept. 2015- rain entering pass. &driver at feet driving. Rust noted under left hood bolts. Hood hydraulic stick failed.

In 2 years of ownership I have replaced 4 ignition coils and the vehicle now needs yet another. At roughly 85000 miles (and year 5) the transmission wave plate failed. Gm would only authorize a rebuild (last week).
