    There's at least one oil discussion topic here on Edmunds, and in this thread the oil is diverging from the topic of first oil change on a LaCrosse, so I'll suggest draining the oil to the new location.

    The 19"-inch wheels are nice but break dust is an "occupational hazard". Anybody knows how to keep the wheels relatively dust free, short of using ceramic break pads? And speaking of ceramic brake pads is that just for genuine exotic sports cars or is it available for the CXS too?

    I've read the manual and cannot get the memory seat to work as described. What am I doing wrong? Tips and secrets are appreciated.

    The memory seats on the LaCrosse do not work. GM is working on a fix for this problem for the past 6 months. Can it be that almost every GM car offers memory seats but the ones in the LaCrosse can't be made to work after 6 months? The dealer can't do any more for the customer if GM isn't focused on fixing the car's problems. GM, not the dealer, also told me that the rear backup camera is not designed to work in full sunlight or in damp weather and that the intermittent white lines or blank screen is normal. I came from another brand and their camera worked flawlessly. Does GM think a customer is stupid?

    I guess I've already posted something similar, but I have a CXL and the memory seats work perfectly on my car. Whether or not they work on the CXS is another matter that I can't speak to.

    Exactly what problem you have with seat memory? Mine works well.

    Tip 1 when set the memory, push memory button first then push #1 or #2 to set memory (reason, the index finger tends to touch the #1 button before the thumb touch the memory button) and it moves the seat instead to set the memory

    Tip 2: push and hold button #1 or #2 until it gets to the final position, release halfway will stop the move.

    Have been off the forum for a while. However, do receive emails on new postings. I also have a problem with poor AM radio reception. It must be the radio since my other car and also my daughters has excellent AM radio reception using the same station(s) and location here in MI. I will be taking my CXS 2010 into dealer next month and have them check it out. I did have problems with radio months ago and they re-programmed it. So, I will report back next month on AM reception. Sorry I can't provide anymore at this time.
    I am still waiting on the proper Wheel Locks since 10/2009.

    Had my first service yesterday, Can confirm for those like me who have a 2010 and thought they had ordered this feature, there is no fix, nor will there be one. You need to have a 2011 with the right package to get it. Oh well.
  • adpcsadpcs Posts: 57
    I can answer this one:

    1. If you use the easy exit system, the seat moves back when you open the door to get out, but when you come back in the car, about 50% of the time it just stays way back, until you press and hold your memory seat position to return it back to the normal position.
    2. The press and hold system is the stupidest thing possible, why not just press and release the memory button?
    3. If you have programmed the key fob to the driver, that does not work either. For example, I have a key fob and my wife has one. If she unlocks the car using her keyfob, the memory should automatically adjust to her settings, and vice versa. That doesnt work.

    I have a CXS which just crossed 5000 miles.
  • johnh7johnh7 Posts: 67
    Check and see if it's really 50% of the time or simply it returns when your car is locked and you use the FOB to unlock it and it doesn't return if your car is unlocked and you simply open the door with the handle.

    That's the way it is designed to work and that's what my car does - every time.
  • adpcsadpcs Posts: 57
    This is what is happening. I turn the car off, open the door, the seat moves back. I lock the door, come back an hour later, unlock the door by pulling the handle, and about 50% of the time, the seat moves forward, the other half, it just sits there in the exit position. So, then, I have to hold the button down that corresponds to my memory seat to put the seat in the correct position.
    The seat moving back and force should be tied to the ignition being turned on / off and not to the door opening and closing.
  • johnh7johnh7 Posts: 67
    All I can tell you is when I hit the unlock button on the FOB, the seat always slides back. When I don't have the car locked (e.g like when it's in my garage) and simply open the door, it never slides back.
  • imidazol97imidazol97 Crossroads of America: US 25 & US 40Posts: 19,798
    Reading closely it sounds like adpcs is unlocking the door without using the FOB? He's just pulling the door handle and, I assume, the car unlocks because of the presence of the key transponder in his pocket.

    You are using the FOB to unlock each time?

    Do I have it right from the posts?
  • johnh7johnh7 Posts: 67

    I'm hitting the unlock button on the FOB
  • kjs8kjs8 Posts: 53
    You are exactly right with your explanation as mine does the same. There is a GM Bulletin out on this flaw and they are working on a fix for the function of the seats. One approach is to tie it into the push to start button and the other is to initiate it on a door unlock command either through the outside handle or key fob. Who knows when it will be available? The side alert that many of us paid for as part of the package and did not get, your right there is no GM documented upgrade to install it on 2010 models. The wiring is there but GM does not want to go to the expense of changing out the mirror assemblies on delivered cars with side alert versions. I bet as an assembly they are expensive.

    If I am going up a slight incline and at a very slow speed and I slowly try to speed by slowly pushing the acclerator - I can almost floor it before the car responds. I also notice this going up a steeper hill at a higher speed. Other times when I floor it to quickly get out of the way of something - it just doesn't move as it should. It also happens on an incline on a freeway entrance when trying to get up to speed.

    I have had this to a dealer who says nothing wrong. I am taking to a second dealer to see if they can get to the bottom of it.

    Has anyone else noticed this and if so what was done to fix it. As it is now it is somewhat on the dangerous side if I need to get out of the way of something.

    Any help would be appreciated.

    Try moving the pedal quickly to gain speed. And do that more frequently. I suspect the computer adapts to your typical driving style. If it senses you want quicker response and that's your typical pattern, it will react quicker.

    If it senses you want slow easy, economical driving patterns, it will give that adapting over a period of time.
  • adpcsadpcs Posts: 57
    Exactly correct, i only use the passive entry system, the key never leaves my pocket.
    i am waiting for the new software gets tiring to hear the dealer say "I've never heard that happening before!"

    After reading this forum, I have seen many outstanding issues that GM/Buick have open and no 'Get Well Date.' Here are the ones I know about. Can we add to this list and have someone/GM/Buick address these issues?
    1. AM Radio Poor Reception
    2. Memory Seats
    3. Side Alert
    4. Wheel Locks
    5. Engine Oil %
    6. .......
    Thank you all for helping to identify and resolve some of these issues. My main take on these are that we should not be trouble shooting these, GM/Buick should be. Dealerships should also be aware of these issues, too.
    I know these are somewhat minor issues, but they are the kind of things that make an owner loose confidence in a Company/Manufacturer/Dealership, etc.

    What is your opinion?
  • asctonyasctony Posts: 46
    Months ago I had some Required Field Action:(RFA) items I identified on this forum. RFAs that I had fixed on my CXS 2010 and what the corrective action was.

    I was hoping that others would identify and post the RFAs that they experienced.

    Maybe I have missed seeing them on this forum. If I did miss them or you have not posted them, please let us know so we can be advised ASAP, rather than waiting until we go in for service. Thank you.

    I have had a great relationship with the dealer, It's GM that is not supplying fixes in a reasonable amount of time for my CXS. I took delivery in early January and within weeks had 6 issues, seats, bluetooth, backup camera, door panel fit, alert mirrors and hesitation. Each issue has no fix offered from GM and the dealer has contacted them on each issue and GM says a fix will come or the issue is normal. Well, each week when one of these things occurs I'm reminded of this lack of concern on GM's part and I wish I had not made this purchase. And this is a great car... I went to a second dealer and their service manager actually told me that GM took a perfectly good LaCrosse model for 2009 and destroyed it with all the electronics that don't work in the 2010. The dealers are frustrated too. I've been asking for six months when will the software fix for the seats be done. Gm has no idea.

    Do we know for sure that the computer has the ability to adapt to one's driving. It is certainly possible to have adaptive programming but it is not easy and I wonder if GM writes that kind of code. Do you have any documentation on this.
  • asctonyasctony Posts: 46
    I originally posted this back in March 09 and have never seen anyone else post any Required Field Actions (Service Updates.) Am I the only one who had these or any other problems like this? I was hoping that we could all contribute to this list to ensure that others are aware of these RFAs. If you feel it is a waste of time just let me know and I will not post these anymore. Thanks for your time.

    Yes. It used to be called Fuzzy Logic ™. Used in auto trannys for many years now. I imagine the newest tech expands on this more than in the past.

    But as has been mentioned, if you were more aggressive with your shifts/accelerator pedal (i.e burn more gas forcing the tranny to relearn a new acquired desire that may only last until you get to work trying to not be late) then it can learn that you want it to shift sooner. And can relearn that you want more sedate shifts later after measuring a softer touch for awhile. But this very thing is why I maintain we ALL would still be better off with manual transmissions. And if you can drive a manual and understand what it means to transfer/balance/manipulate engine torque to the wheels, and then to the road, then it proves a greater confidence behind the wheel. Anyone who can drive stick, usually are safer drivers when the roads turn slippery too.

    Anyway, at least in Europe they still offer many manual trannys in a greater choice of cars. And they manage to do autobahn speeds with no more incidence of crashes than here. Imagine. Over there they drive. Here we (most) are basically only sitting behind the wheel.
  • cooleyddcooleydd Posts: 105
    Sounds reasonable to me. I will drive more aggressively for awhile and see if it makes any difference. I do naturally tend to drive "softly". By the way with over 60 years driving experience from Model T's, trucks and lots of different autos I agree to your comments about stick shifts. However it is much easier to let the automatic transmissions (and any fuzzy logic) do the work. And when driving in San Francisco you really learn to appreciate the automatic transmission.
  • crkyolfrtcrkyolfrt Posts: 2,345
    And when driving in San Francisco you really learn to appreciate the automatic transmission.

    Yes, I sure could see that alright. And in stop and go on freeway parking lots of course.

    I meant to mention that what you described earlier seemed extra unusual though. It sounded like the engine lacked power and responsiveness to a greater degree than just caused by lazy tranny shifts. Let us know how it turns out ok? and good luck :)

    Don't forget, you can make the tranny shift into lower gear by manually moving the shift lever, so you might try that the next time it seems extra lazy on a bad hill. Just don't forget and leave it there of course..
  • cooleyddcooleydd Posts: 105
    I have tried to get it to happen in the lower gear via the shift level and have had no luck.

    It really seems to in a gear and seems not to shift (up or down) or accelerate - there is a long pause and then it will kick in. It is hard to duplicate but scares one a bit when it happens. I will drive more aggressively to see if it changes anything.

    We picked up our new 2010 Lacrosse on 7/8/2010 and when we asked the new
    car salesman about the field checks or service updates he said that they routinely check for any outstanding items not eliminated at the manufacturing plant. He had the answer right away so we felt comfortable that all outstanding RFA's had a standard procedure to make sure they were "cleared". You post alerted us to that concern so we asked. BTW, the car has been oustanding after 2K miles only.
  • bwiabwia Boston Posts: 1,562
    So there is a problem with the memory seat after all. After some frustrating and unsuccessful attempts to get the memory seat to work I took the Lacrosse back to the dealer with the expectation that a technician would explain what I was doing wrong. But the fault was not with me but with the memory seat module.

    The dealer ordered the part and it should arrive in about a week. The fix appears to be an elaborate job as it will involve removing the seat to install the new module. I hope the techs are well trained because I would be upset if they make matters worse by improperly reinstalling the seat. Nonetheless, I will give an update as soon as the problem is corrected.

  • asctonyasctony Posts: 46
    Thanks for your response. I guess my concern is that there should be some way of finding this out from On-Star, or going directly into GM/Buick by VIN online to see if your car needs any work. Normally cars are not brought into the dealership until you need work or an oil change. I firmly believe that it would to everyone's benefit if we could somehow track new problems.
