| My wife was driving the vehicle and approached a stop sign. once she tried going again the car would not accelerate and we had to tow it to the dealer. they said the transmission went out @ 68,000 miles? also the waterpump, powersteering pump. master cylinder, as well as something with an air bag connector. the air bag connector has been going on and off for the last two years since we bought it two years ago as a gm certified pre-owned vehicle. i am not sure how this vehicle has not been recalled. | |||

| I purchased a 2008 gmc acadia one year ago. it seemed like we had made a god sent deal and now we are finding out that the transmission is going out. our family doesn't have a whole lot of money to just throw away and we put down $5000 and now we are looking down the barrell of a transmission. not fair considering the dealership apparently knew it was about to go out. i was driving with 3 other teens in my car and all of a sudden it wouldn't go faster than 25 mph. | |||

| I was driving down the highway on friday afternoon at 65 mph when i tried to accelerate to pass a vehicle, and the engine just revved nearly to the redline. i was able to reach the exit, where i pulled over, put the car in park, then back into drive to start off again. at this point, the car would not shift out of 1st gear. i was able to make it to a midas shop for a check and they stated that the transmission was shot. called the local gmc dealer and had the car towed there for a diagnostic. they called saturday afternoon and confirmed that the transmission needs to be replaced at a cost of $3700. the car is 24k miles under warranty mileage, but just happens to be 5 months outside of the 5 year warranty window. i then called gmc customer care for redress and was told they would investigate. received a call today ad they left a message, but only to ask which dealership it was at, even though i provided that info on saturday, to include the phone number to the service department. the transmission problem seems to very widespread based on the number of responses on various websites, but doesn't seem that it is being seriously addressed by gm management and is a very serious safety concern. | |||

| On two occasions after putting the vehicle in park, turning off the ignition, removing the key and exiting the vehicle, it rolled back and only stopped when driver jumped back in and applied the brake. this occurred on a flat garage surface (no incline) on both occasions, with different drivers on each occasion. gmc dealer says they can not replicate the issue and there is nothing to repair. this vehicle is dangerous, as it can roll back unexpectedly, potentially causing serious bodily injury or death, or damage to physical property. gmc recalled the 2009 acadia for the same issue previously, but maintains there are no issues with my vehicle. i found additional complaints for this issue on the 2008 acadia on the internet as well, so this issue is not unique to me. *tr | |||

| I'm concerned about the safety of the 2008 gmc acadia and similar gm vehicles, as i was driving with my family out of town when the transmission suddenly had problems shifting in and out of gears. while driving the weekend after thanksgiving and approximately 4 hours from home, our 2008 gmc acadia started down-shifting hard after passing a vehicle on the highway. a few minutes later this repeated, and then the check engine light came on. soon after, when almost to our destination, the vehicle had no power to get up hills on the highway, and once we exited, could barely make it off the exit ramp and through a very busy intersection. it seemed to be stuck in a high gear. being late friday afternoon on a holiday weekend and now in a rural area, there weren't any repair shops that were either open or could look at it. so we had to rent a car and attempt to drive the acadia back another 40-50 miles to get to a chevy dealer that was open and could at least checkout the transmission. on saturday they confirmed it was the transmission, and specifically the 3-5-r wave plate, but the vehicle wouldn't be ready until the following week. later i researched and found this to be a common problem, but it still wasn't being recalled by gm. luckily we were barely (1 month) inside of our power train warranty and didn't get hurt. i will say that the chevy dealer that did the repair was great to work with, especially since we were from out of town. but now i'm worried about being able to safely drive this vehicle for any significant distance from our home. *tr | |||

| We were coming home from family on thanksgiving night and the check engine light came on as we were getting on the highway. when we got off the highway and onto our exit, we hit a red light. luckily, it was on a hill, because my husband hit the gas and we didn't go anywhere. the car just revved up to around 4 rpm's. we finally gained some momentum going down the hill and then the car drove just fine again. next stop light, same thing...only this time, we were making a left hand turn and facing on-coming traffic. it took everything it had and about 20 seconds just to roll through the intersection! if our kids had been in the car with us, this could have been a major accident if we had been hit! the car was towed to the mechanics and was found to be a broken wave plate. there are numerous complaints about the wave plates in the acadia's, traverse's, and the outlook's, but no recall. i am also only 1 month out of the power train warranty! please help! thank you! *tr | |||

| Been going through forums and know a few people who have purchased acadia's and the transmission gives out on these cars really quick and it's a 5000 dollar fix that gmc knows about and refuses to fix and at 50,000 miles their is no reason you should need a new transmission i personally am two weeks out of warranty with a 22000 dollar sitting brick and expected to pay for poor production quality this should be addressed on the national level and is extremely unfair to loyal tax payers to be almost robbed in plain daylight | |||

| Our vehicle has had the air bag service light on for a very long time, when we got the recall notice, we took it in to the dealership and they stated that our vehicle was fine and our light was caused by a different problem. as time has gone by, it has done the rest of the items listed on the recall such as on/off light remaining off with a passenger in the seat and now it actually flashes back and forth with or without a passenger. our power steering has been making a whine sound since 2009. it has only worsened over time and now has depreciated our vehicles value for a trade-in. we are completely dissatified with the quality of vehicle we have gotten. i would not recommend an acadia based on the reliabilty of gmc and the lack of responsibility to fix problems that are obviously on the manufacturing end. we know several others having the same problem with 2008 acadia and have found many forums of people discussing their issues and it appears that the 2008 has the greatest amount of issues. we have been advised to seek legal action. | |||

| Recently, when loading the cargo area of my 08 gmc acadia, the vehicle started rolling forward (the ignition was off, and in park). it rolled approximately 2 ft. before park engaged. (my 2 grandsons were playing in my driveway a short distance away). after having the vehicle checked out at the gmc dealership where it was purchased the service mgr told me that this is a normal condition, acceptable by gm, that the parking gear pawl can actually roll up to 2 ft. before engaging. it doesn't seem probable, or even possible this can be considered to be a safe condition. when i asked who would be responsible for injuries resulting from this situation his response was, gm. | |||

| I noticed that when driving on an expressway and would attempt to pass a slower moving vehicle, as i would move into the passing lane and attempt to accelerate, the car would hesitate for a few seconds, lose speed, then suddenly downshift and accelerate at an unexpected rate. i also noticed that the car would unexpededly accelerate or decelerate under normal driving conditions. i bought the vehicle to the dealer for repair, they responded that they could find nothing wrong, but the what i was experiencing was characteristic of the 6-speed transmission on the vehicle. the problem continued and i found it dangerous. i returned the vehicle and the dealer's remedy was to reset the transmission computer. during this time, i also noticed that the service stabilitrac and traction control warning would come on. onstar recommended i shut off the engine to reset the system. i found this only happened when i first used the car in the mornings to go to work. again, the dealer said there was nothing wrong and the computers were showing no codes -- they also stated that they could not duplicate the problem. i got the car back from the dealer and it happened again - at 7:00 am. i called onstar and they gave me two codes. i bought the car back to the dealer and gave him the codes. it now seems that there were two defective sensors controlling the stabilitrac / traction control system and how they communicate with the transmission. i was told that gm is changing manufacturers on the sensors. i have not had use of the car since the beginning of june and am still waiting for gm to produce these parts. in the meantime, unexpected acceleration, deceleration, and gear shifting was occurring under all driving situations causing -- in my mind -- a danger to myself, my passengers, and others. the dealer has had the car on five different occasions since june 8. this last service they have had the car since july 20. | |||

| We purchased a new gmc acadia on 6/16/08. since our purchase, we have experienced a dangerous transmission issue. after coasting downhill, the vehicle fails to downshift which causes a rapid deceleration when traveling uphill. this rapid loss of speed puts the driver in the hazardous situation of a rear end/chain reaction collision on the road gmc claims to have a fix, but this fix causes the documented gas mileage to be reduced by at least 2-3 miles per gallon. they have attempted to fix this issue twice in the last 4 weeks to no avail. *tr | |||

| To state recognition of the facts: fwd wheel-spin was reported to achieve forward vehicle movement with the current fwd system on wet surfaces of this vehicle. the drivers correction factors to regain traction includes, de-throttle (back peddle the engine) to lower the torque level and thereby hopefully regain traction with the roadbed when the road conditions exist as reported. reported details to gm and driving experiences driving issues include: 1.cana traction control device be added to retard the throttle and rpm to prevent wheel-spin? 2.are the correct tires / tire compounds being used? 3.will wheel-spin endanger the lifeline and longevity of this transmission or motor? 4.is damage is being introduced into the mechanical parts of the engine and transmission, what can we expect? 5.the current implementations require the driver to functionality drive regaining control of the front tires, which is considered abnormal therefore becoming a hazard to the normal traffic flow as show. 6.the current implementations require the driver to back-pedal the throttle motor and transmission; the observed conditions occur over 2000 rpm of acceleration, next the motor / fwd systems then over-spin the motor and transmission up to 3500 rpm before the driver can back-pedal the throttle, regain control, and resume acceleration while attempting to remain safe in normal traffic flow.. to summarize gm (karen) has reported in a verbal phone conversation with me, held on 12/10/08 that a stabilock transmission on a 2008 acadia is within specifications to have fwd tire-spin and or traction loss when acceleration exceeds 2000 rpm on wet roads and surfaces and the vehicle handling conditions are normal. karen also states she has no issues with the reported problems as described, and maybe, i (the driver lacks experience driving a front wheel drive vehicle). *tr | |||

| 1. while traveling on an interstate highway, the vehicle's stabilitrak control abruptly shut down, and the brakes locked with light depressions of the pedal. (stabilitrak controls the vehicle's traction control, anti-lock brakes, and roll-prevention program.) 2. the failure has occurred approximately 5 times; on one occasion, the engine stalled in addition to the above. consequences were as described above. 3. the vehicle was taken on an urgent basis to the gmc dealer the following day. the dealer advised that the problem is due to play in the camshaft, which sends an erroneous signal to the stabilitrak, causing it to shut down. the dealer advised that repair will require replacement of cylinder heads and other equipment, which is a draconian procedure which will take a week or more. in addition, the dealer advised that the problem is causing permanently damage to the vehicle's drivetrain which worsens with miles driven. the dealer further advised that repair parts would not be available for at least 8 weeks because the problem is widespread in the vehicle line and gm refuses to manufacture parts in sufficient quantities to meet the national demand. almost 8 weeks after reporting the problem, the problem remains unrepaired, and gm has refused one written request and one written demand for immediate correction of the problem, despite this being an immediate threat to occupant safety in that it shuts down the vehicle's most important electronic safety components, including traction control, anti-lock brakes, and the anti-roll-over program. *tr | |||
