Vehicle Shudder Problems of GMC Acadia

It has been since I bought the vehicle . . . Gas gauge is intermittent and cross traffic alerts go off randomly (with no traffic or obstructions) paint has had to be redone leather replaced trim redone etc. . . The car almost killed me and my children, I'm driving down the freeway at 70mph and suddenly I lost control of the vehicle it slowed down to 49 then 25 lost steering and able to drift to the side before the whole vehicle started shaking violently and I shut it down as I believed it would explode (I was terrified) I called a dealer and they asked if I turned it off and on again ? engine light came on traction control would not renegade and message said decreasing power to engine while it was happening and abs light on . . . All failures. . . Managed to get to destination but vehicle was sluggish and jumping gears felt really jerky. . . 4th start all lights disappeared and although car was still sluggish figured might have been an electrical fault made appointment for dealership told it would cost . . . Parker car drove other vehicle then had to use this one and same thing happened again so took to dealership they couldn't figure out the codes was told had broken engine mount (said it was on backorder as it's been happening a lot) and was sent on my way to see if it would happen again. That weekend it happened again had figured out by then that 5-7 starts it would act up. Took to dealership and left running so they could see what was wrong (failed transmission, steering column block pump sensor etc replaced. Was given a rental GMC by herts and you guess it same thing on freeway all the lights on the dash start lighting up failed traction eas and breaks (super scary brand new only 600 miles on that car) switched out vehicle for a safer car (Toyota) I'm unable to check more boxes but speed and control were also affected.

Under acceleration the vehicle shutters between 1100-2300 rpm the vehicle shakes and is a very common issue with all of these vehicles this major transmission issue must be addressed as this is a wave plate issue in the functionality of the transmission my vehicle is currently at 86,000 miles and is experiencing this issue and must me addressed if not this can result in a sudden loss in power on the highway causing a potential accident this recall was executed on the 2007-10 Acadia, traverse, outlook. Number 10126145.

Car make some vibration and loss power at between 2000 and 2700 rpm, when I make some aceletion on low rpm, and make some noise when transmition need change gear, up o down, on low rpm, dealer in first time, say the problem was a throttle body, and I fixed, but a problem keep going, went I returner to dealer shop, now they say it's a tramition problem.

Vehicle shudders and engine surges if engine rpms drop under 22oo. Car does not drive smoothly. Has tripped into "limp home mode" while driving on 4 lane highway at 60mph. Vehicle had to be towed. Dealer "said there was not error code to repair", have taken it in on 4 different occasions with a repair to fuel relay repair, motor mount, and twice with no repair before warranty was up, now outside of warranty in mileage. This vehicle is not safe. Problem has been going on since August 2017.

When the vehicle automatically goes into v4 mode there is a vibration inside the cabin. The vibration also sounds like a boom noise inside the cabin and the vehicle shakes while driving. The problem seems to occur at 1500-1700 rpms and will continue until you accelerate and make the vehicle go back into v6 mode. Dealer attempted to fix the problem on 2 occasions but was unable to. Dealer acknowledged the problem and categorized it as a vibration, drone, flutter or boom noise inside the cabin while vehicle is in afm v4 mode. Problem has not been fixed.

Vehicle shudders and jerks at all speeds. It is particularly worse at lower speeds. The automatic transmission is acting like someone is popping the clutch on an manual transmission. It is scary and dangerous to drive when this is happening, however it only happens intermittently. Have found many similar complaints via google, however cannot get dealer to address the issue as no error codes are present and they cannot recreate the issue.

Twice in the past week I have had the same problem with the stability track sensor turning off while driving. When this happened the engine power decreased. When trying to get the vehicle off the road, it was like I had lost power steering because it was a fight to turn the wheel. Prior to this we have also noticed that when the vehicle shifts gears, quite often it is a very hard shift to the point it shakes the whole car and feels like it is stalling. Not sure if that is a transmission issue or something to do with the fuel injection.

On 03/07/15 at approximately 1715 at tyler state park our vehicle was backed into the parking space on a slight incline at cabin one. Our 3 year old daughter was in our 2012 GMC Acadia in the driver seat and our friend’s 9 year old son was in the passenger seat; with the vehicle in park the ignition turned off and the keys in my husband pocket. Our 3 year old daughter was able to get the vehicle out of park and into drive, causing the vehicle to roll forward down the incline, across the street and hitting two trees. This caused damage to the bumper and right quarter panel causing the passenger door to catch on the metal frame when opening the door and the front end of vehicle shakes when driven between 65mph-70 mph. Both children were ok with just bumps on their heads. I called the gm dealer in tyler, TX and was advised by tim to contact a gm dealer when I returned home since the vehicle was drivable and we were on vacation. On Monday March 16, 2015 at approximately 0715 I called texan GMC and spoke with tony and advised him of what has happened with the vehicle while on vacation. Tony advised me I could bring the vehicle in to have the recalls fixed but I would need to call GMC customer service @ 800-222-1020 and get and incident report started with them and see when they would like to have a technician take a look at the vehicle. I called GMC spoke with cheryl and she gave me a claim #71-1451210965 I then took the vehicle to have diagnostic testing done on Monday 03/16015 and was called on Monday 03//23/2015 advising me that there were no finding of a malfunction with the vehicle and that gm will not be fixing any damage to my vehicle that was a result to this incident. No matter their findings there is a malfunction somewhere and I feel that gm does not want to admit to there being a malfunction. I just want the issue fixed so this does not happen again.

I was leaving work and noticed a shudder in the vehicle. Didn't think much of it at the time. When I got about 2 miles from my home the vehicle seemed to loose power. Engine would rev but could not get much speed out of it. Made it home and had vehicle towed to dealer next day. Dealer diagnosed issue as 3-5-r wave plate in the transmission broke. Ended up costing over $5,300 to replace transmission. After repairs I did some research and saw that there were hundreds (from the few websites I visited. . There are probably many more) of complaints by consumers who owned 2008 through 2011 Acadias as well as other general motor corporation (GMC) vehicles that had the same issue with the wave plate failing. Called GMC and they told me since the repair work was already done there was nothing they could do. Apparently from reading all the posts gm is aware of the issue but did nothing about it. My bigger issue is what if this occurred on the highway in the middle of winter and we were left stranded? this could have been a serious issue and potentially put lives in danger if traveling on the highway or remote locations. GMC should be held accountable for this manufacturing defect and should extend the warranty on vehicles with these types of transmissions and reimburse all of us who had to shell out our hard earned money to get the vehicle repaired.

I had purchased the vehicle used from what I had thought was a reputable dealer, boy was I wrong. I was on my way home with it from the dealer an hour and a half drive 1 way , going down the interstate at about 65 mph, when the vehicle started to shake something severe , and the rpm,s went wild. I slowed down , but the shake , vibration continued. Finally it did straighten out, and I got home. A couple days later on my way to work the engine light came on, and than the service all wheel drive system light came on. The next day my dad who is a mechanic, drove it and it shook and vibrated so bad , he thought the wheels were falling off. Came back and put it in the workshop and checked the wheels for tightness, they were ok. Noticed a rather large coolant leak above the water pump ,, seemed to be coming from under intake area. Called the dealer and said we were bringing it back on a trailer. On 1 / 1 / 15 at about 9:45 am dropped off at the dealer, told them again what the problems were and left it there. On 1 / 5 / 15 the dealer called us and indicated there was a upper radiator hose that the clamp was loose. I told them it was not and my dad knows where it was from. They also stated that they drove it and could not find any problems with it. After telling me that they said that they are a Ford dealer and do not have the tools to diagnose the vehicle. Right after that the general manager says that he did notice a problem with shifting , but its nothing to worry about. I said than you put your family in the vehicle and take them for a drive , because I will not put myself with my 3, and 5 year old kids in it. He said he will look at it again tomorrow. I will never buy another gm product ever again.

Vehicle intermittently shifts to a high gear when starting to accelerate or starting from a stop without pressing the gas. As a result, the vehicle starts to shake and sputter, much like what would happen if trying to start from a stop in 4th gear with a manual transmission. Check engine light comes on, traction control and stabilitrak error appears on the display. Pressing the gas simply makes the vehicle jerk. After a few seconds, the error corrects itself and everything clears. Unable to duplicate at will. Took to the dealership today after this has happened around 5 times in the last month; however, no error codes we logged in the computer. Service department unable to do anything.

During acceleration the vehicle vibrates when going between 35 and 45 mph. Was not able to reproduce issue at dealership last fall, but is now getting much worse. Happens almost everytime the vehicle accelerates.

While driving out of town this weekend we noticed quite a few problems with the vehicle shaking/vibrating a lot while on the interstate and when driving up inclines it would start to surge back and forth. After some doing some research online it seems as if the transmission is starting to show signs of the common wave plate problem in this vehicle. This needs to be addressed, as well as all the other common issues that this platform has, by gm.

Was driving car and transmission started acting up. Car would shake when shifting gears. Service engine light came on. Took to service garage and said would need to rebuild transmission.

Transmission started slipping. I would pull out onto a street and it would slip and I almost got his by a car. I took it in repeatedly to dealer and they couldn't duplicate and after repeatedly taking it back and them keeping it for a month they finally replaced the transmission. Repeated steering issues. I took it in constantly and was told nothing wrong but after looking at it myself I found melted bushing and after being told all that had been replaced already. Steering problems from day 1. 4 times of having power steering replaced and steering column and every time I got the vehicle back the vibration was worse, today I found the problem on my own. The rack and pinion has a major leak. Not sure how repeated trips to the dealership and they couldn't see this. My steering also locks up while driving almost hit a car. . And the dealership never has loaners so im stuck driving an unsafe vehicle while I wait because I was told I can only go where I bought my vehicle because of the extended warranty. This vehicle goes in to the shop and as soon as it is picked up it needs to go right back the same day. Worst vehicle and most unsafe of anything I've ever owned.

Tl-the contact owns a 2008 GMC Acadia. The contact stated while driving approximately 40 mph, the vehicle began to shake and decelerated to 10 mph independently. The engine then stalled. Upon restarting, the transmission failed to shift into reverse. The contact was able to resume in operation. The vehicle was taken to an authorized dealer for diagnosis. The technician stated that the transmission wave plate fractured which caused internal damage. The transmission was replaced at the owner's expense. The manufacturer was made aware of the problem. The approximate failure mileage was 70,000. Js.

While traveling down the highway with family the check engine light came on and the vehicle began shake and jerk violently. I pulled to the side of the road and the vehicle would not go into reverse and forward made a terrible grinding noise and could not go over 10 miles an hour which is very dangerous driving at dusk. Got the car home and took to the dealer the next morning. We were 2 months past our 100 k 5 year power train warranty and gm would only give a small discount on a transmission rebuild. Not once did they ask about our safety.

While accelerating vehicle started to shake between 30-40 mph. Shaking subsides at around 45 mph. This started around may 2012 with 99,000 miles on the car. Took the car to the dealer to have it checked out because I though it was the transmission. They thought the tires needed to be rotated and balanced, which did not fix the problem. By 106,000 miles it was so bad that the vehicle could not be driven safely. This time the dealership said it was the motor mounts, which did not fix the problem. I had them keep the car until they found the problem. After 2 weeks they determined that it was the transmission! after the transmission was replaced the vehicle drives great. I have read hundreds of complaints on the Acadia transmission and there are likely tens of thousands of cases just like mine. There should be a recall for the transmission on this vehicle.
