Buick LaCrosse Transmission Problems



  • I have had two incidents where my 2010 Buick LaCrosse has stopped cold. The first time I was at a gas station. I finished pumping gas and when I went to start the car it would go no faster than 5 mph. It then shut off. I was driving on a busy highway at about 70 mph and the car shut off. Now the car is having issues with the powersteering and leaking. The car only has 33K miles. Has anyone else had these problems?

  • I am having a similar problem with my 2010 LaCrosse , but with mine the car after being on for a lil while goes into a parking brake mode. The engine light turns on, the parking brake light turns on and the car slows to 1 mph. Sometimes before this happens the doorlocks go nuts rapidly going up and down.
    I video'd the park brake problem on my iphone and posted it to show the dealer whom has tried to fix it 3 times.. My next move is lemon law because it is a potential danger to drive with my family on the highway.

  • Buick55,

    I see you're already working with a dealership - are you planning on revisiting them again? If we can be of any assistance, please don't hesitate to contact us via email (send your name/user name, last 8 of your VIN, contact information, and the name of your dealership).

    All the best,

  • Each time my car shut off, the car displayed similar actions as shown in your video. Tthe engine light came on, the park assist would turn off and then the car shut off. The best experience of all was calling the Buick customer care to get the car towed. I was told they would tow the car to the nearest dealer which was not near my home and I would "have to get myself home". I called the dealer for assistance only to get nowhere. So I am sitting in a parking lot after rolling the car off a busy freeway. No one seemed to care that a brand new car had just stopped while I was traveling over 60 miles per hour on the freeway. And then to be told to find myself a ride home was a bit more than I could stand. It amazes me how excited they are to sell you a car but show no ownership when the car has a problem. I guess I should be grateful I did not lose my life.
  • Lefttoyota,

    I am interested to hear how things have gone since your last post; would you mind posting an update?

  • When we got our Lacrosse my wife and daughter both complained of being able to smell gasoline inside the vehicle.
    Of late I have been able to smell it as well. What could cause the odor of gasoline to seep into the car?
    Please advise.

  • I get a p0716 & p0717 code when the engine light come on. The engine light may stay on for a while then will stay out for a while. It's like it goes through a test when the engine is started and if everything is okay the light stays out. So okay, it may be a transmition input speed senser or it may be intermitent wiring; not sure which but to change the input speed senser they want to drop the engine/transmition out to get to the transmition to remove a cover on the transmition to get to the speed senser. I am not sure how these speed senser act when they go bad. Are they intermitant or do they fail completely? This is a 2006 Buick Lacrose with a 3.8 engine and 45,000 miles. Does anyone have any thought on this or Recommendations before I spend the money and time to drop the engine out?
  • Hello buick 55. Well I'm sorry for your problems with your car, but it seems as though you and I are in the same shoes, along with a few others. I also have a 2010 Buick Lacrosse with the same problems. My doors lock and unlock repeatedly while driving, my car shuts down while driving, leaving me with absolutely no control of this car, then afterwards here comes the malfunction light and park light, with no warnings prior to shutting down. I've been stranded, my car has been to the dealer multiple times and I've spoken with GMC multiple times. I have also posted it on you tube. I can go on and on with this lemon, but all I can say is seek help. Seems like the dealership and GMC isn't worried about the potentially dangerous and potentially fatal incidents that can occur due to these malfunction vehicles. Trust, I have expressed my concerns and more about this, about my safety, my family, and the safety of others around this car, Im not trying to kill myself or anyone else. I've been fighting this matter a few months after I purchased my car, straight off the delivery truck. I'm not stopping until I'm heard, my life and the lives of others is worth it.
  • Did take the car in to the dealer. This was the second time I had done this. The first did not result in any find. The second time they found a valve that was leaking fumes under the hood. Once replaced the odor abated.

    However it is back again. I will have it back to the dealer again tomorrow.

  • The Buick is at the dealer as I write this.

    Niagara Motors
    in Niagara on the Lake, Ontario
    905 468 2145

    The service person looking after this is Mike

    My name is:

    Jim Collard

    The last 8 of the VIN are: f148687

    The car will be at the dealer until next week as a part is on its way from the US. and will not get here before the weekend.


    The dealer has arranged a rental car for the duration.

    That said. My initial concern before the gas odor with this vehicle was the hard manner in which the automatic transmission down shifted as you decelerated through 30 miles per hour.

    The Lacrosse we have on loan from Budget does not do this. The down shift is very smooth and the ride is much better than the lacrosse we own.

    We have asked Mike to take another look at this challenge.

    Can you suggest anything that would make the trany work better?

    Jim Collard
  • Good morning, Mr. Collard,

    Thank you for the update! I went to look into our database for information on any warranty/recall information I could send your way, but unfortunately wasn't able to. I did a double-count of the VIN information posted here and found that there are only 7 digits, and our systems require 8. I apologize for that.

    I see that vehicle is having some difficulty with downshifting, but as I don't have technical information available to me am unable to make any suggestions. Has Mike been able to successfully diagnose this? I would call and follow up but, as I'm based in the US, am only able to contact United States dealerships.

    I would be happy to do as much as I can, though, if you were to send us the last you’re your VIN.

  • Thank you for your patience!

    When I looked into your vehicle's information in our system, I noticed that there was a transmission calibration update performed on your vehicle a few years back. It may be worth checking with your dealership to see if there are any further transmission calibration updates available for your LaCrosse.

    Just for your information, you are still within your Bumper-to-Bumper warranty until 12/17/2014 or 80,058 KM, whichever comes first, your Corrosion Limited Warranty until 12/17/2016, and your Powertrain Limited Warranty until 12/17/2015 or 160,058 KM, whichever comes first.

    I hope this is helpful for you,

    I saw in an earlier post that you stated if you were given the VIN you could check to see if there are any recalls on a particular vehicle, I am looking at a 2012 LaCrosse and wondering if this is possible to do for this car?
  • gmcustsvcsarahgmcustsvcsarah Posts: 1,964
    That is correct, tokun5. If you wanted to get me the last 8 digits of the VIN, I could look into this for you! Are you experiencing difficulties with your LaCrosse?

  • I wish I had read this before I bought a new 2012 LaCrosse. Just got it on Monday and had it for 1 hour and Transmission went out. It has 44 Miles on it. Dealer told me they have had no issues with this sort of problem. BULL!!!
