    I also have a problem with a vibration with my 2011 Lacrosse CXS with only 3800 miles. Bought the car in Nov 2010,took the car to the dealership with less than 500 miles,they said nothing was wrong,but replaced all 4 tires hoping this would help.IT DID NOT! After 10-12 trips back and forth to 2 different Buick dealership, another new set of tires at 3500 miles,numerous road force balances, a certified letter to BRIAN SWEENEY,VP OF BUICK SALES AND SERVICE, MY PROBLEM IS STILL THERE!! As you can tell by the mileage, I drive my 2500HD Silverado more because it rides better. The dealers do not want to (or didn't) check anything else,I/E, shocks/struts,rotors, drive train,etc! Funny thing is that both dealerships let me drive another new unsold 2011 Lacrosse, both had the same vibration problem. Buick needs to get someone involved in solving this vibration problem. I love my Lacrosse,a very beautiful car,but hate the ride. This is my 10th new GM vehicle since 1992. Good luck on getting help.

    I apologize for the problems you are experiencing with your new vehicle. By chance have you spoken with GM Customer Assistance and has the dealership involved Technical Assistance? Please keep me posted.

    Thank you,
    Caron, GM Customer Service
  • I have a 2010 CXS with just over 10,000 miles on it. When I went out this morning the battery was dead. Charged it up and it was fine. Couldn't find any left on. The only thing that was out of the ordinary was the night before the car wanted to pick up on the bluetooth while I was outside of the garage with the car not running. Does the bluetooth stay on when the car is not running. Would it have stayed on after the call when I walked out of range to continue my phone call? Thanks
  • Mine is 19 months into the vibration issue. It is not a fun car to drive because of this. In partial defence of some dealers, when they call GM for assistance, because GM does not know what is causing the vibration the first thing to do is balance the wheels. It is very unfortunate that a cause can not be determined. I am so dissapointed with my LaCrosse and the lack of interest by GM that I have vowed never to but another GM. If you get a case number from GM customer service, keep it going until it is totally resolved. Once it gets closed, you are forgotten by GM. I wished now that I would have demanded a buy back early on when the miles were lower.

    I ran across the same issue recently. Phone started acting stupid. It had not been like that previously, that is if within 60 feet of vehicle, it would want to transfer to car, even when the car has been off for some time. I would normally expect to see that bluetooth was connecting when the vehicle was started. More stupid GM programming/updates?
  • e_net_ridere_net_rider Posts: 1,380
    What sort of vibration are you and the chief now experiencing?
    I had a bad tire on mine, but think they needed to be reminded tires should only be changed in pairs. I could really tell the difference with one new and other over 10K on front.
    This stuff makes for a horrible owners experience. Since both have CXS, do both have GY or Michelins.
    Dave, I don't know about your area, but here the lemon law is figured from the time of first complaint on issue. First complaint at 300 miles, you get reimbursed back to then, as a percentage of 120K. We have two years, 24K miles coverage under lemon. I need to read through it again because my issues have been repeating, but there are just so darned many I can easily say Edsel. I don't know what issues were with it, but I'd bet I have far more when you count them up.
    Good luck to say the least.
    I'm seriously considering doing a large report to the safety people. Doing it at a technical level that might be above their investigators, and if they get it wrong, shame on them. It is not a good time to be looking for a job.

    If you read through the service bulletins and recall issues, via this site, you might get sick to your stomach.
    But I thought I'd mention that CAF again. I've noticed that sometimes it did not seem to have a high enough fan speed to cool effectively. I had been judging that from air exiting vent once interior cooled and fan slowed. A little while back I got to playing with the setting for the auto control of fan speed. I have had mine on high since new. Certainly any other setting during hours of sun coming into vehicle, is too slow. I believe the filter has become adequately plugged to restrict the air flow. Just turned 12K and it still don't remove odors, fine dust, etc.
    I think GM screwed up with its implementation. On Sable I had with one, the filter was strictly for outside air. That way there was no restriction with a dirty filter when recirculating the air. And worry of burning up fan motor which GM has mentioned as a concern. And as I observed, restricted flow across the evaporator is not a good thing either.

    The owner’s manual states:
    "The system can be used while the ignition is in ON/RUN or ACC/ACCESSORY. The range of the Bluetooth system can be up to 9.1m(30 ft.)."
    If you are experiencing concerns, I would recommend visiting your dealer of choice. Please keep me posted.

    Found it open again this morning. The range on these FOBs is fantastic, but I'm tired of finding my trunk open.
    I had not really checked, but wonder now if it is also unlocking vehicle and I've just not noticed.
    Obviously the buttons are getting bumped when I carry the FOB. Thank you GM for another lousy design.

    Christina, hi, wondered where you've been.
    GM or Buick has messed up the programming with bluetooth and this vehicle. In my 09 Malibu, the car bluetooth would not activate until the power was changed from off. With this one, if within range and vehicle off, it transfers.
    More fine GM programming logic.
  • crankeeecrankeee Posts: 298
    rider: is this Bluetooth/FOB malfunction occurring only on the cars with the keyless entry/proximity detection feature? We avoided that little "improvement" on our 2010 CXL on purpose. The keyless start button withe proximity detection programming has been a problem on others cars also.
    Just wondering if it is only showing up on the keyless entry models????
    Regards Crankee

    I'm still out here on the forums. Have you mentioned it to the the dealer? I can look into your VIN and see if there is some kind of update. Just let me know.
    GM Customer Service
  • e_net_ridere_net_rider Posts: 1,380
    Finding the trunk open frequently, I'd suspect is due to the increased range of the remote start FOB. I had remote start on 09 Malibu, and sometimes I found it unlatched. As to doors being unlocked, they probably were too, but you just don't think about checking to make sure doors were latched when approaching to get in. This certainly opens a can of worms. You might find someone in your vehicle, especially during those times such people actively seek unlocked vehicles.
    As to the bluetooth, I would say it is not connected to the remote start FOB function. Other than that I don't know because I have no way at present to compare with vehicles differently equipped. I can tell you that Bluetooth seemed to work perfectly until around May 31.
  • e_net_ridere_net_rider Posts: 1,380
    Christina, I've had so many problems it is hard to keep up with what dealer was informed of. But I suspect you are correct. That was the morning I encountered a no start and called for jump, after several unsuccessful attempts because they wanted VIN and everytime I got near vehicle to read it the phone auto transferred to interior. Perhaps I thought fixing one would fix the other. I drove straight to dealer once jumped and wanted other issues fixed as well. I started to drive off in loaner when I remembered that I forgot to tell them of sticking caliper. I circled around and reported it. It has happened twice on this vehicle. At least twice on the Malibu, and on the Malibu, one occasion was not at all pleasant. This could easily have been the same on this vehicle. There is no way for the systems to know if a caliper has stuck. Since close to 90% of your braking is done by front, and you lose one side, you don't have much left. Forcing the pedal harder to keep from shooting through the red light, at least one of the automatic systems kicked in. I don't recall sliding, so maybe it was not the ABS. But because I was having to input to steering to attempt keeping straight, it might have been the stability control. If that worked as written, then it would have been releasing the one good brake at front and the opposite cornered rear in an effort to right the vehicle. YES, even less braking. Would you accept "could not duplicate" just because it is intermittant? The pull when the caliper is sticking is toward oncoming traffic!
    More in next post.

    I would appreciate that much. VIN 1G4GE5GD0BF183398
    It would be nice to have a list of all updates or changes.
    And if you are able, show which ones are reported as having been done. I've dealt with a deal on the other end of some of my trips, and they said they put one in which I was unaware of. I am aware that my main dealer had been made aware of what might be a connected issue. But I don't know what the update was supposed to address specifically. And it might be connected to the fact that mine no longer cools well at startup.
    Thank You.

    Rider: You are the only poster with such a myriad of problems and your car is a CXS. The reason for my question is to isolate the problem with the key fob functions to cars with remote or keyless entry. Same as the engine problems; 3.0L, 3.6L, I-4 or all types. The software on the keyless entry setup is much different in that it does not require a physical action by the operator. When we put our 2010 CXL w/o the keyless entry to bed at night, it has stayed silent. we also use our cell phones within range but the OnStar/Bluetooth (shared system) does NOT activate or link to the phone.
    consumers gave Ford a knock for their system being too complicated or distracting for a driver to use while operating the car.
    Good luck with your effort to exchange your CXS another GM car. It may be more difficult than your Malibu turn in previously due to the new GM.
  • e_net_ridere_net_rider Posts: 1,380
    I'm sure there are differences with software/computer issues depending upon options.
    The only distinction I am totally aware of is if you have the seat memory issue, GM says, if SBZA is installed, do not replace module. Re-program it.
    But, I'd almost bet GM is not totally correct in that statement. They seem to be assuming that every vehicle with SBZA got a particular part number seat memory module because prior to that the answer was to change the module for a particular part number. Or the SBZA is in the seat module. Which then might make sense that my SBZA was broken when they were working on the seat issue.
  • crankeeecrankeee Posts: 298
    rider: I know that they frequently piggyback or patch new or additional software onto existing well testd software. The quirks are stirred up when a new app affects an existing program that worked OK on it's own.
  • e_net_ridere_net_rider Posts: 1,380
    Are you talking about the programming in this vehicle or something else?
    Such were the quirks of some of MS OS. To keep the size down, in some OS they relied heavily on DLL's within the OS for operability of other programs. And some of those programs needed different versions of the DLL to work. Often installing those programs overwrote they system DLL and broke other things. Neither was necessary since the new DLL could have been put in the folder with the program executable and worked fine, without disturbing the MS version. But even MS was constantly changing versions trying to create an all inclusive version, but that ususally meant larger files as well.
    Once hardware got fast enough to satisfy the home user MS did away with that and protected the OS from having its versions of files replaced.
    The big issue here seems to be lack of knowing what the OS is. If it was open license, we'd have much better than current issues. It seems GM has terrible programmers. And maybe terrible hardware. Many of GM fixes say to reprogram the module, that is whatever is failing. Not to do an update programming, but to reinstall the same crap. That can hardly be a fix for anything but another failure in time.

    I was referring to the code that is programmed into the onboard computer(s) for the various functions like doors, A/C, keyless entry/start and other hardware controlled by the prom or flash memory. We have had to have a few prom items "reflashed" to reestablish the original code due to inoperability. On our 2010 CXL the only thing sofar is the bluetooth/Onstar system "forgot" my phone (secondary) but remebered the wife's (primary).
    That's better than losing the transmission or A/C code or engine management. S___ happens esp. with software. The more complicated the more fragile IMO.
    check today's recall for 2012 Lacross to reprogram brake module - that's what i was commenting on. I'm pleased that Gm catchs such things.
  • e_net_ridere_net_rider Posts: 1,380
    These days such is no longer rocket science. It is just computer. The days where hardware was pressed to the max are gone and trying to shortcut code so it does not overload the CPU and other hardware. For at least a decade, computers have reached the point they can automatically take off an airplane, fly it to its destination more efficiently than the pilot, and put it to within two feet of the ground. ( As I said, that was over a decade ago, so maybe they are now putting wheels on ground). Sorry butt excuses don't cut it when it comes to blaming the computer. Computers can be extremely reliable and if not, it is the idiot who put it together. GM.
    What, they catch one occasionally?
    What exactly was wrong? And what might they be reprogramming to? An update, or just putting the same back in because the system is not fault proof. (modern computers are)
    If what you suggest were true in the world of aviation, they'd be falling out of the sky like a bunch of mosquitoes that just got sprayed. Excuses of this magnitude are not excuseable.
  • crankeeecrankeee Posts: 298
    HMMMMM. Seems like we have morphed back to that perfect world again. Methinks that there are humans involved in writing, testing and installing the software that runs those awesome computers you refer to. My limited experience with the humans has demonstrated some predictable flaws.
    good luck with returning your CXS to the new GM.
  • e_net_ridere_net_rider Posts: 1,380
    As I said, I'm tired of lame excuses.
    So I thought I'd give you all a bit to think about. What might be an industry wide problem that is being ignored.
    Systems involved, braking, specifically a sticking caliper on front. ABS, and ESC (electronic stability control).
    Without those added electronics, if you had a sticking caliper, you just stopped the best you could considering road surface and tire traction and the ability of the other front caliper to stop you without loss of control.
    Add ABS, one wheel not braking because of stuck caliper, the other doing the best it can being controlled by ABS if slipping occurs.
    Add ESC, electronic stability control. Some are really stupid systems and do nothing but cut power. I think that could be called having your foot off accelerator and on brake. I would hope federal safety has killed that design.
    Most are advanced to the point that they calculate steering angles and input and even use accelerometers. Along with controlling power to wheels, they will modulate the brakes and on corners to create corrective steering of the vehicle. Sounds really neat, right?
    Think about what happens if you have a sticking caliper and the vehicle pulls/steers to one side because of that. (that would have happened without ESC).
    But with ESC, say left front caliper sticks, no braking on that corner, and since nearly 90% of your braking is done on the front, you've lost 45% of your stopping power. Also vehicle will pull or veer to the right. ESC, in an effort to make corrective action would release the right front brake and apply left front brake, which is not working. Depending upon programming, it might realize that caliper is stuck since it never reaches the point where brake locks stopping the sensor from showing any motion, at which point the ABS would try to modulate, but again it is stuck. What happens in this scenario?
    On the 09 Malibu, I felt modulating of brake, but continued to veer with very poor stopping, past where I should have been able to stop without ESC.
    On this car, both times it stuck, it veered and since I had plenty of room, I released the pedal and reapplied. Absolutely no hint of corrective action and it worked when I reapplied, fortunately. I can only guess what would have happened if it was a must stop. Would it have stopped me in the shortest possible distance or tried to keep vehicle straight but take a much longer stopping distance?
    If this was my only concern, I'd demand a new brake job, complete. Afterall, if this happened on one of my older vehicles I'd immediately do a thorough brake job.
    Just because it is intermittant, it does not mean it is not happening, therefore ignore. That is much the position I got from the GM district rep today. Even being able to see the SBZA was not alerting until a vehicle was at the bumper, he denied anything being wrong. That made me light up like a July 4th display at his butt.
    If it was just one intermittant problem or non safety related, I could probably work through it, but not this mess.
    Still no reply on what portable HDD actually works.
    Resolution: I'm sad but happy. My wife is elated.
    The guy here who has been posting about they are built by humans, blagh, blagh. I heard the same exact thing today. More stuff I will accept when pigs fly.
    I do really hope
    GM is able to get its business together. Failure to recognize problems is failure to fix them!

    Despite mistakes, it can be gotten done. Especially on computers where there is no worry of someone hacking. Excuses come too cheaply. It is not like there is a steep learning curve as in building the very first computer or creating a program language. All the heavy lifting has been done. GM just needed to bring in the expertise.
    I hate to think this could be like GM's many early efforts to build an aluminum engine. I had one of those pieces of junk. 215 CI V8 used around 1962 in small Buicks and Olds. Not there only attempt either. They finally got smart enough to realize they had some problem that they could not get around so when they wanted one for the Corvette, they contracted with a company that had lots of experience with aluminum engines. I've heard it is a pretty good engine, but no personal experience. The company is Mercury Marine as in boat motors.
    They may also have learned lesson with diesels. The last they built of cars with those I heard used an Allison in vehicles like the Cutlass Cierra. I heard they were good, or at least far better than the 350 conversion.
    I am rambling and suddenly realize that maybe outsourcing is the problem with this car. China?
    Just waiting for GM to do paperwork.
    I really hate the idea of shopping again.

    Lisa: I posted previously on this site that we had a similar experience. Our area was hit by some very serious tornadoes with the result being no phone service due to no power. Many cell providers were also out of service. We were most fortunate in the ordeal, but did not have power for 4-5 days. The old AT&T land lines with the low voltage setup did work if you had that system and a corded phone that did not need electricity to operate. Another neat surprise - OnStar also worked as it apparently was able to tag with any operating cell tower (some services had generators).
    Great emergency plan backup service. We are senior citizens so the safe and sound package was cost effective with OnStar's help. Keep up the good work!

    OnStar has an expense side but it had a very beneficial side for us as well. Our son was a field commander for the high school marching band. We had stopped by with lunch for him and he laid his keys in the rear armrest of our leSabre while he ate. We left and later he called saying his keys were in our backseat--he needed the electronic equipment for the band practice that had restarted and which he had locked in the trunk of the Cobalt.

    We were at a cruise-in 25 miles away. My wife realized all we had to do was call OnStar to unlock the car for him so he could unlock the trunk and get to the electronics. 5 to 10 minutes later he had the equipment.

    This summer he worked in downtown Columbus living in an apartment by himself near campus; that was 80 miles away. Because he could access the unlock feature for the Cobalt, I secreted a set of keys for the Cobalt, key for the apartment, and a spare cell phone (Tracfone) in the car. If he lost keys or locked himself out of the apartment or the car, all he needed was someone else's or his own cell phone to call OnSTar to unlock and get access to replacements for the keys.

    I'm sorry I am unable to get you a list of all updates and changes for your vehicle. My recommendation for your situation is to speak with your service adviser. I would recommend asking them to contact Technical Assistance. I am unable to diagnosis your vehicle via the internet; however, with your vehicle battery going dead, and the vehicle picking up your phone calls, it makes me think that something is staying on which is transferring your calls and killing your battery. Please keep me updated on your progress with this. If you would like we can set up a case with Customer Assistance for this concern. Please feel free to email me.

  • Hi crankee,

    We like to feature our subscriber stories on our blog. If you go over to you can submit yours there, and it might be featured on the site!
  • Caron, yes I have been working with GM customer service since January,2011.I guess what bothers me is that the dealership,working in conjunction with technical assistance,have never checked anything other than tires and wheels. If that did not solve the problem, why didn!t they check the drive train,struts,rotors,etc.,until they find the problem? This lets me know they don!t want to take the time to find the cause,which feels like out of balance tires, after reading my message you are responding to you can see what I have been going thru. Thanks for your concern,will you help me?
