GMC Acadia Transmission Problems

To Whom It May Concern:

I am writing you today to express my dissatisfaction with my new 2010 GMC Acadia I purchased on June 11, 2010. I have had numerous problems with the car and employees of the dealership.

It started with the purchase. We went to SNK Dealership in Springfield, IL. When I told the salesman what I wanted on my car he stated that he could not find any car with everything I wanted on it. I requested DVD, Navigation, XM radio, and sunroof on a white GMC Acadia SLT2. 2 days later, he found one that was red, I took it. Then, he said he could not negotioate the price because he was only making $100.00 and SNK dealership was only making $400.00 on the deal. I found this incredulous.

A short time after buying the car I noticed windshield washer fluid on our garage floor. I took it back to SNK and sat there for 1 1/2 hour with my elderly mother only to have the mechanic come out and tell me they couldn't find anything wrong. He agreed to go back and look again and a half hour later he came to tell me that the problem was in the rear of the car. I tried to explain that the leak was in the front of the car under the motor. He immediately became aggitated and put his hand up and stated, (and I quote) "I will slow down for you. I will talk more slowly so that you can understand." I stood up and told him not to talk down to me. He walked off and I went to look for the salesperson who sold me the car. He tried to tell me that I misunderstood. When I went back to the waiting room a woman who had been sitting there stated to me, "Good for you." She heard everything and stated that they talked down to her, too. It turned out to be a windshield washer pump for the rear and could have been explained very easily without rudeness.

They ordered the part and fixed it later that week. We were asked by the salesman not to return the " GMC Buyer Survey" at all if we were going to put anything negative on it. My husband and I agreed we could not in good conscious, so we did not fill it out or send it in.

My husband and I both feel that the car never shifted right. There seemed to be a delay in shifting and when stopped at a stop sign on a slight incline it rolls backward as soon as you take your foot off the brake. I asked SNK about this and the mechanic laughed and stated that "...the car is heavy."

Then, on Friday, August 13th, I started the car and put it in reverse. The car jerked as if I was pushing on the gas and immediately the check engine lite, "check stabilitrak" and the traction lite came on. It was charging higher than normal and the RPM's were around 5-6 at 60 miles per hour. I called Onstar and they did a diagnostic and found 3 problems. Onstar called a dealer in Naperville, IL but they wouldn't get me in until Thursday, August 19th. I drove it a little farther and called Onstar again. They tried to call another GMC dealer in the area but noone answered. So Onstar arranged a tow and rental car.

I was informed that my rental car would only be paid for if it was a GMC product and the only GMC they had was an HHR which looked an felt like a gocart. I wanted and expected a car at least similar to the one I owned.

My car was towed to Bill Kay in Downers Grove, Illinois. I received a call from the mechanic later that night. I spoke with the mechanic on Monday and was told he would order parts and repair transmission. I asked about the other two problems Onstar found and was told they would take care of them, too. I later informed him of the recall on rear seat and he stated he would take care of it, too. Thursday morning I called and was told the parts are on back order and my car would not be done until next week at the earliest. I began packing to go back to Springfield and left shortly afterward. I received a call, after I was on the road, that some of the parts had come in so I turned around came back to wait. Friday the rest of the parts came in and I arrived at the dealership around 5:30 to pick up my car. The check engine lite was on and it was charging higher than normal. I also noticed a small scratch and chip on the left front bumper and oil or transmission fluid on my driver floor matt. I pointed these things out to the mechanic. He told me I could drive the car and repair it in Springfield. He said it was an oxygen sensor and something about emissions. He also denied scratching the car stating that it looks like a rock chip.

When I arrived at my home in Springfield the trunk would not open and the dash lights had been flashing on and off.

Back in Springfield I and took it to Friendly Chevrolet where it sits now. They have been very nice and easy to work with.

I am also VERY concerned about the resale or trade-in value of my car. I would not, and do not know anyone who would, buy a car that the transmission went out and had all these problems two months after it was purchased.

While I am writing this letter I would also like to mention the things I dislike about the car itself.

-the front air-conditioner vents are surrounded by shiny silver which reflects the sunlight in my eyes

-no power tilt steering wheel

-grooves in floor where rear seat slides are exposed and rear floor matt seems too small

-plastic around console and lower portion of front seats is easily moved by slight touch

-only holds 1 CD or 1 DVD at a time

-gas mileage is 14 MPG city and 16 MPG on highway which is a big issue since I drive 25,000 miles a year.

I just thought someone should know these things and would appreciate your insight on this matter.

****This is the letter I would like to send. Just don't know who to send it too. Please anyone help.

  • I have a 2007 Acadia SLT-2 that has 115,000 miles because I drive 120 miles a day roundtrip to work. I have had the common problems that everyone seems to have had: power steering pump, water leakage, transmission software updated, cam sensor, car rolling when parked on a hill even when emergency brake is on, etc.

    But, this past Saturday did it for me. I was passing a car and when I sped up to pass, the accelerator stuck three times (i thought the engine was going to blow the RPMs went so high) before I could get the car off the road without a major accident. Luckily, there was no other traffic in front of me. It was the scariest moment of my life and my four year-old daughter was in the car too.

    I took it to the dealership (scared to death it was going to happen again) and was told the timing chains were worn but shouldn't be at 115,000 miles and the clutch something on the transmission was shifting through from third to fifth. Because my 100,000 mile warranty had expired, it would cost me $4500 plus tax to repair. Needless to say I am getting a lawyer to help me fight this. 115,000 miles or not, my car should not put me in danger like that when obviously GM knows there is a problem with the transmission on these vehicles as everyone can see from all of these posts.

    I am trying to find information about a class action lawsuit if anyone knows anything please reply. Thanks.
  • good luck trying to get GM to repair their junk! Now that it is government motors there is no incentive to fix anything!
  • I purchased my GMC Acadia in April of 2007 and have had numerous problems. The first transmission failed at 79,029 miles and the second one has failed at 143,348 miles. Prior to both transmission failures the car would not smoothly accelerate but "jerk" forward when the gas pedal was pushed on the highway. Another problem that occurred prior to both transmission failures was the engine would "race". I suspect that there is a design flaw in the transmission on this car. Does anyone have similar experiences.
  • i have never had so much stress over a car before! and this is the newest car i have ever owned! and also the worse! i bought the car w 3700 miles on it. and it now has 6100 miles on it! i pay 500 a month for the car! and here are the problems i have had w it.....i broke down in 100 degree car told me to turn engine off now!!! i had to get towed from nj to pa...then was told the abeloff the gm place i took my car to would not be able to even look at the car for a day or 2. no one said anything to me about a rental...and i didn't know much about my warranty etc....i had a big party camping trip i was planning...i needed a i went to enterprise i told them about my brandy new car sitting in the shop...and they gave me a rental...and because it wasnt a gm rental car i had to pay 180 bucks for the rental...even thou the part and everything was under warranty....well be asured i learned my lesson w that happ on 7/17/10....everything seemed ok with the car....i agree w everyone w the gas mileage and some other issues....but i did noticed that when i come to a stop sign and i step on the gas it almost seems like the car doesnt go takes longer to get my speed up...2 times i have almost got rearended because of this probelm! begininng of november out of now where i put my car in reverse and it seemed the time i pulled out of my driveway and put it in drive my check engine light came on....the car was maybe like stuck in third gear???!!! it sounded horrible and was making a loud banging noise like my transmission was gonna fall out....i drove it to the dealer....the told me i needed my transmission to be rebuilt!! i am not ok w my 2008 having a rebuilt transmission in it!! after calling gmc i got this lady charlie who is my case supervisor.....she was very rude i didnt like her at all....but her words to me where i assure our gm tecs are the finest...i was like really they are the ones that built the dam thing in the 1st place she said i dont appreciate the sarcasm! wow....but this is not it not only was the tranny messed up...but my drive shaft needed to be replace yep not cover under warranty and my power steering was leaking...and my gas gage was freaking out bouncing all over the place....yep all not covered under warranty....i raised hell and only had to pay 190 bucks for all of this....however i dont feel i should have had to pay anything!!! now on turkey day me and my mom are in my car on my way to my bar to cook thanksgiving dinner for alot of friends family and homeless when yep...i pull out of my driveway in reverse and then in drive i put it and the car does the extact same thing it did before...i had no choice but to drive it the 10miles to my place...i had to get there...i made it there..and my hubby and 2 friends drove the car...all experience the same thing....the check engine light was on and it again was like it was stuck in third took everything in me not to cry and freak out on turkey day...and i did pull myself together...the next day i call abeloffs and tell them...they get it towed to them...then they tell me nothing is wrong with the check engine light no stuck in gear...the car i just error codes etc....i am like whatever that is bs...i beleive the reset my computer or changed a sensor and they dont want to tell me because they know i am at my wits end....i am so close to getting a lawyer it isnt even funny. and the more that the have to fix on it the better chance i have in court. i had to pay for the tow there also...because they said nothing was wrong w my car.....i will never buy a gm again husband wont...and my 3 kids wont...and i have no probelm sharing my story w all of my custmors..being a bartender well u get to talk alot....and it isnt a threat to gm i feel that people need to know...this just isnt fair!!! i want to trade the car in asap...but i will owe money on it..i have only had it for alittle of a year...and that stinks...and a part of me wants to keep the car and hope it does it again because then....well then i really have a case. i had consider talking to gm and telling them how unsafe i feel in this car and maybe getting a 2011 maybe they worked out the kinks etc...and maybe they could help me out w a good deal to not owe money on this car....but the truth is i wont feel safe in it....not after reading so many people are having the same probelms as me and then some are having even more....i honestly dont know what i am going to do...i wont drive the car on the parkway etc i am scared it will stick or idk. i was suppose to drive my mom home after turkey day...but she lives 2 hours there and 2 hours back and driving on the parkway etc....i was to worried so my brother got stuck taking her home....and the worse part is his car is like a 2002 piece of junk...and it wwas safer to take that then my 2008 500 dollar a month piece of junk :lemon:

    I purchased a GMC Acadia in 2007 and have about 175,000 miles on it. The first transmission failed at about 75,000 miles, the second one about 145,000 miles and the third one at 175,000 miles. I am also beign told the whole engine is bad. Prior to all three transmission failures the car would not smoothly accelerate but "jerk" forward when the gas pedal was pushed on the highway. Another problem that occurred prior to all three transmission failures was the engine would "race". I suspect that there is a design flaw in the transmission on this car. Does anyone have similar experiences. Frustrated in Tampa.

    Hey. i wanted to let you iknow that you aren't the only one with this problem. I've taken in to the local GM dealership about 25 times since October 29, 2010 with the SAME problem. They will not do anything until it shoots out a trouble code. I am very frustrated because i am sure it is going to leave us stranded on the road one day. I've put a call in to GM and all they are willing to do is offer me 1,500 off a new vehicle. I have not accepted that offer because I think it is a waste of my time. We are to the point where we are ready to just park it and never use it.
  • I have a 2007 Acadia. We purchased it about a year ago. It only has 32,000 miles on it.
    About 70% of the time when you accelerate, it takes several seconds for it to respond.
    This has created a couple of dangerous situations.
    I'm not sure how the throttle is designed but it's certainly not of good quality.
    This is extremely unsafe and Acadia owners need to be aware.
    GM really has lost a lot of quality over recent years. Interior looks and feels more like a Mattel Toy product.

  • I have a 2008 (I posted on this site in May, 2011 about my Acadia ) - we had the same identical problem and this was the start of engine failure. The 361 litre engine is a BAD engine. GM claimed "improper maintenance" but would NEVER put it in writing - we regularly changed the oil and had proof - the car only had 34,000 miles on it. The dealer - without our permission - took the engine out of the car, and tore it down to millions of small pieces, thus making it impossible to put together and put back in our car. We hired a lawyer, The Atchison Firm, in Mobile, AL, and 1 letter later - we got a NEW engine with the warranty continued until 100,000 miles and ALL of our rental car expenses reimbursed. Don't be afraid to take them can win!
  • I have an issue too. Around 54K on my 2007. Same throttle issues and now transmission. I had it into the dealer 2 weeks ago reporting trans issues and they stated no issue, but charged be $300 to flush the trans.

    This morning on the way to work, the car seems to be locked in 1st gear. Then the check engine light came on. Luckily it was a couple miles from work, but now I am not sure how I am getting the car back to the dealer.

    Customer Service from GM is horrible.

    Whenever I heard there was a problem with the transmission. I would say I don't have that problem. Until today!! I have a GMC Acadia 2007, took it in to dealer. Transmission problem. I am not happy. But I guess known issue and GMC doing nothing for it. I mean it's all over the Internet. So all of us owners are s.o.l?
  • gmcustsvcgmcustsvc Posts: 4,252
    Have you taken your vehicle to the dealer? If not, I would recommend starting there. I would be happy to look into recall information for you vehicle, I would just need you to email me your VIN. Have a great day!

  • I just finished a weekend trip when my transmission failed on the Interstate highway. RPM jumped to 4000 while speed rapidly declined, then transmission warning lamp came on. OnStar checked and the code indicated a stuck solenoid. Towed to dealer. Didn't take them long to decide they needed to pull the transmission to diagnose further. The next status update I got was they were overhauling the transmission -- not exactly sure what's being replaced but sounds like a major repair. Thankful for the 5yr/100K factory warranty. Also thankful that the dealer repair shop is handling this so expediently.

    I had flushed/changed transmission fluid at 49K. Transmission has always seemed to jerk/slip, but until it failed I was always told this is how this model behaves, it is "normal".

    I just had my 2007 Arcadia SLT2 towed to the dealership today for transmission failure. They said Number 5 Solenoid is stuck and has other issues. It has 74000 miles on it. Love this vehicle. first time we had any problems. Also had engine code 496 I believe, something about a fuel evaporator valve.

    I got my Acadia back last Thursday (only 4 days in the shop to rebuild the transmission). It required a total rebuild, metal shavings were throughout the fluid and all the parts heavily scored. But, they took care of it 100% -- no questions asked. Couldn't ask for better service (except, maybe that the problem didn't occur at all!)

    One funny thing, I received a monthly OnStar report in the midst of the transmission rebuild. It reported "no issues found" with engine/transmission. LOL. Here is what that looked like" -_o.jpg">

    I have a 2007 Acadia. A few days ago I my car ceased to move in the middle of an intersection on an overpass. I had both kids in the car and the dog. I didn't feel safe in the car as people flew past and it certainly wasn't safe to get out of the car. The whole point of me choosing this car was to have room for kids, dogs and stuff and to feel safe! It's the transmission! Again!! This is the
    second time it's gone out on me!

    It is extremely frustrating! I am waiting to hear news. The car has been at the dealership since Monday!
  • I had this exact same thing happen to us in our 2008 GMC Acadia last fall. They told us it was a stuck solenoid too and replaced the transmission. NOW, I just took it in with issues and it is the transmission again. Apparently there is a solenoid that is bad again.

    I bought a 2008 Acadia in april 2008 with 7,000 miles. I really Don't know what to do anymore. One month after i purchased this suv, It has been in the shop every three months with problems. How can we keep making our payments when we are spending more in the shop. the airbag gets fixed every other month. The electrical failed. The engine wouldn't turn off. The roof leaked. The transmission is going out , the engine jerks when i am idol and wants to die. This vehicle literally goes in the shop every other month for problems. I have had it serviced at the same dealership since purchased. Every time it goes in the shop the price is more expensive.
