• Hint: Use a descriptive title for your new message
    If you're looking for help and want to draw people in who can assist you, use a descriptive subject title when posting your message. In other words, "2008 LaCrosse" isn't going to indicate to anybody that you need help. However, "Need help with my 2008 LaCrosse" will. Be as descriptive as you can. Please use common sense...

  1. Door locks not working

    As I understand your description of the symptoms, ALL the door lock mechanisms are attempting to lock but do not complete the task. The only answer that I can conceive is that of a series resistance in the power supply to all the door locks or a low battery voltage (not the same as the charging...
  2. Help me locate Push to start transmitter control module in 2015 Lacrosse

    When the FOB battery is low or dead, the car can be started if the FOB is placed in a recess at the bottom of the center console (under the removable basket). Have you looked there?
  3. What's a good Sunshade you would recommend

    In 1997, we moved to Tucson, Arizona which has a lot of sun and high temperatures. If a sunshade is not used, it can be impossible to even hold the steering wheel when returning to the vehicle. We used the Eclipse Sun Shade (Windshield Sun Shade | Custom Retractable Car Sun Shade) and have...
  4. Remote start problem

    One other outside the box thought. When I carried my cell phone in the same pocket as the key fob, the car would not unlock when I approached the car and pushed the door handle button. After that, when I tried the key fob, it would not unlock the car. It appeared that the control unit in the...
  5. Issues with 2010 Lacrosse v6?

    We had a 2010. At just past 100k miles, the air conditioner compressor would no longer suck the fluid/gas so no cooling. It cost about $450 to have it replaced. Other than that just the usual wear items (battery, tires). The brake pads still did not need replacing. We are now on our second...
  6. Air leak at base of valve stem - question

    Last fall, a deer ran out of the woods across four lanes of traffic and into the driver's side of the car just before the rear door. Deer dead. $4,000 later, slow leak in left rear tire. Finally found a tear slit at the base of the valve stem. Dealer replaced the valve stem without having to...
  7. Trailer Hitch

    We have a 750 pound mower that occasionally needs to be taken to the dealer for warranty work or service. I found that General Motors lists the Buick LaCrosse with the 3.6L engine as being capable of towing up to 1,000 pounds. Has anyone tried this? I have found several brands of trailer...
  8. Droning Noise

    2010 CXS with Michelin Pilot Sport A/S3 tires replaced at 55k miles; now at 75k miles. Tire rotation at 70k miles. We suddenly began to notice a droning noise at 75k miles that was independent of the engine RPM or the transmission gear selection. It is solely dependent, it appears, on the...
  9. Fuel Economy Calculations

    Awhile back, there was a thread discussing the accuracy of the average fuel economy readout. Those who were manually calculating the fuel economy between fill ups were finding some discrepancies between the displayed average miles per gallon and their own calculations. A recent article in...
  10. Can the LaCrosse Be Hacked?

    From the Norton Security web site: Can Your Car Be Hacked? Kim Boatman Find Under: Prevention You might be behind the wheel, but increasingly, computers control your car’s every function. Microprocessors direct braking, acceleration and even the horn these days. “Because they are hidden...
  11. Undocumented Features

    For the last 35 years, each vehicle that I have purchased has had undocumented features. Now I find these same undocumented features in my 2010 Buick LaCrosse CXS. They are not listed on the order sheet, nor the build sheet, nor even in the brochure. For example, when I am approaching a curve...
  12. Cadillac LaCrosse

    Have you seen the 2013 Cadillac "LaCrosse?" The similarities are striking. http://www.youtube.com/watch?v=NSqETRrhiMs&list=UU2dBZuI6gS-jv7PCIDXkXag&index=2&feature=plcp I do note that there is an inside trunk release on the driver's door armrest.
  13. Automatic Recirculation

    I have the recirculation button set to the automatic mode which is to shut off (most) of the outside air when the car senses pollution. It does seem to work such as when I drive through a plume of burning leaves or wood. But there does not appear to be any indication when this mode switches...
  14. Daytime Running Lights

    The brochure for the 2010 LaCrosse says that the daytime running lights are "switchable." I realize that in Canada on the Allure that they cannot be turned off but here in the US it is an option by the manufacturer. I cannot find any information in my owners manual regarding the technique to...
  15. Key FOB Problems

    Is it just me or does anyone else find the CSX key FOB to be the worst part of the Buick LaCrosse experience. The buttons are not recessed so I am often backing out of the garage to find that, sometime prior, the trunk release has been pressed unbeknownst to me while in my pocket. I can only...
  16. Intelligent Assist Brakes

    I am here today to praise the intelligent assist brake function on our 2010 Buick LaCrosse. When we were considering this car, I did not understand what this feature provided. A search revealed that, when the brake pedal is applied quickly and strongly, the brake system augments the force that...
