    We're sorry that you're having difficulties getting this AFL concern addressed with your dealership.

    I finally brought my 2011 CXS in today and the issue was resolved in about 30 minutes. The service manager said that they were very familiar with the problem as there is a technical bulletin out on it. (Probably not seriuos enough to prompt a recall)
    All that was required was a reprogramming of the lighting system. The notation on the work order reads as follows:
    -- MS N9657 Headlamp Control Module

    Don't know what that means but the warning light has gone away and the headlights seems to be working fine. By the way, they gave me a copy of the instructions for the service technician and the only thing I can discern from it is "J2534 Pass Thru: Final Instructions and Programming Complete."

    Finally, I want to thank my original dealership in Hanover, MA for doing such a fine job. By comparison, the dealership closer to my home had no clue. As a matter of fact they had never heard the term "AFL Lamps" before much less to fix the problem.

    Sounds like you might have USB port. These fixes for reprogramming the dealer gets from GM. If they install with normal test equipment, it takes them 1/2 hour plus. Once the dealer gets that program, they can put it on a USB thumb drive, advised to do so by GM. GM claims it then takes only 2 minutes to install update.
  • I am unable to set the clock once we went off DST. I have been to the dealership three times with no luck. I have a 2010 LaCrosse CXL. I did not have this problem in the past. I can set it manually and it will keep the correct time until I shut off the engine. Does anyone know how to set the clock so it keeps the correct time?
  • Sounds like your dealer is not very adept. This one is simple. The software that governs that needs to be re-programmed. Same thing happened to my CXS with NAV. There is a software update that addresses this.

    Got a new 2021 LaCrosse yesterday. I've had memory seats before and never liked them so on this car we won't bother to engage it. My wife and I are fine with the same setting so no aggravation necessary. Keeping as much of the tech stuff off the board as possible. Turn on the key and drive. Wish me luck.

    Joe, mine is doing the same thing. Had it checked when the oil was changed at a Chevy dealer (Same company, just the Chevy dealer was 15 miles closer). The looked for codes in the radio. Nothing. Now, I lose the volume, it "resets" itself, And when it comes back on, 12:00, Jan 1,2006 and no GPS for about 2 min. Then is sets to correct date, but GMT. Hopefully that's all it needs is a reflash. Gonna take it to the Buick shop. At least they work w/ the Nav system on a reg basis.

    We hope all goes well with your visit, cooterbfd! Looking forward to an update.

  • Did you ever get an answer to this question? Did you end up buying this headunit? I am also considering, but, like you, hesitant to buy something like that from China. I have the 2012 Lacrosse Premium 1 and love it, but REALLY regret to getting the touchscreen option :(
  • I had the same problem with my 2010 CXS. The reprogram fixed it last year. This year when I took it in, it was out of warranty. They told me that the bulletin they had said that if the reprogram didn't work, that the radio needed to be replaced. They decided to make a good faith warranty since I had been in the year before with the same problem. They replaced my radio. The only problem was that I couldn't pause or rewind like I was able to do before. They ended up getting another radio. Apparently this time it was designed for the 2012 models. According to the dealership they had to wait for some guy to write a new program so that the newer model radio would work correctly with my 2010 model. Everything works fine now.

    I am unable to set the clock once we went off DST.

    The same thing has happened to me too on my 2011 CXS. I just can't get the darn clock to retain daylight savings time. It resets as soon as the engine is turned off.
    Anybody else having this problem, and was it satisfactorily resolved by the dealer?
  • My 2010 CXS is doing the same. The dealer is ordering an entirely new Radio/NAV System to be installed next week. It appears Buick has had hit or miss reliability on them. I'm glad it's not being replaced on my nickel. Service advisor told me they run about $600. If I were Buick I'd seriously be going back on whoever manufactured these units, I'm sure they're probably outsourced. Still Loving the Buick though! A fine example of quality American Engineering!

    This brings up an interesting dilemma. I intend to keep my Buick CXS beyond the warranty period, but because the electronic components have a tendency to fail I am strongly leaning toward buying an extended service repair agreement.

    Most, including me, feel that an extended warranty is a waste of money but in the last few months my computer died, dishwasher went on the blink and this week my dryer and now my CXS. All of these failures were due electronic malfunctions.

    Are electronic components such as NAV, HUD, Radio, etc. covered by the GMPP warranty?

    Keep us updated on how the replacement of the radio goes, joelippard3!

    The problem with extended warranties is that they represent a high cost from very shady companies. If you can buy one from GM, the cost will be very high. These policies have exclusions and limitations that can make getting paid for repairs a nightmare. They constantly change ownership --- beware. One of the highest industries with consumer negative experiences. I'd take my chances.

    Take the 1200 bucks or so for a good GM warranty and put it in the bank. If you can add a few bucks in here or there and hope for the best.

    Most of the technology in the cars is pretty reliable. If you do have a problem a few years down the road, you will have a little cushion to fix it.

    My 2010 CXS is doing the same. The dealer is ordering an entirely new Radio/NAV System to be installed next week.

    It took a while, but the clock was reset to DST. This required some reprogramming which changed all my settings but I am happy with the result.

    Now I have a new annoying problem--an intermittent ticking that sounds like a time bomb. As usual, the techs can't duplicate the condition.

    Does anyone know if there's been any resolution on this problem (bogging down on the verge of stumbling)? My 2010 LAX has been doing it for 6-8 months. I don't have the time or the money to let my local Buick dealership to give me the runaround (poor history with the sales dept and I'd rather not give them another nickel).
