GM Releases Software Update For 2023 Cadillac Lyriq

General Motors has released a software update for the 2023 Cadillac Lyriq as part of a new Customer Satisfaction Program. The new bulletin is tagged as N232428540, and includes a software update that reprograms multiple onboard modules. This specific Customer Satisfaction Program only applies to the 2023 model-year Lyriq.

The 2023 Cadillac Lyriq just got a new software update.

According to GM, certain units of the 2023 Cadillac Lyriq may require a software update to “improve the customer experience and optimize future over-the-air updates.” The new software update will be performed by the dealer, and does not require the addition of any physical parts or components.

The new 2023 Cadillac Lyriq Customer Satisfaction Program is similar to a separate Customer Satisfaction Program released for the 2024 Chevy Blazer EV. As GM Authority covered previously, certain units of the 2024 Chevy Blazer EV also require a software update to be performed by a dealer in order to “improve the customer experience and optimize future over-the-air updates.” The update also affects units of the Blazer EV affected by a recent stop-sale order, with those units released from the stop-sale order once the update has been applied.

The 2023 Lyriq is the first production-spec Cadillac to equip an all-electric powertrain, and has faced several teething issues since its initial rollout, including a cracking liftgate panel, a display screen recall, and a separate vehicle software management system update in 2023.

As a reminder, the 2023 Cadillac Lyriq offers both rear-wheel-drive and all-wheel-drive variants, with rear-wheel-drive variants equipped with a single rear-mounted motor doling out 340 horsepower and 325 pound-feet of torque, and all-wheel-drive variants equipped with two electric motors, one per axle, for a combined output of 500 horsepower and 450 pound-feet of torque. Both model variants feature GM Ultium batteries and GM Ultium Drive motors.

The GM BEV3 platform provides the underpinnings, with production taking place at the GM Spring Hill plant in Tennessee.

  2. I have been very pleased with my 2024 Lyriq. Everything works well and I’ve been on four road trips. Not sure what exactly this update will be for. I’ve had less than 4 months, have driven 6,000 miles.
    Excellent car — quiet, comfortable, luxurious , fast and fun.

    1. That is good to hear. Have you had any problems at all? If so, could you describe them? Thanks.

      1. I have not had any problems. It has taken me some time to learn how to use the various features on the display screen. The display screen is where the buttons are for the Home Link garage/gate opener buttons. The glove box release is on the display screen.

      2. Hi Jeff –

        Just responding to your question….. As per this article only deals with 2023s, I have a 2023 Luxury Lyriq which is currently in for dealer service so I’d imagine they will perform the software update while they have it.

        As far as problems go:
        I’ve had several. Firstly, the 12 volt battery went dead when the ‘alternator replacement’ didn’t feel like charging the car. Then, when approaching a car wash, I got a ‘Service High Voltage Battery’ indication which in effect meant the car would not recharge any longer, even on 110.

        That problem was a biggie. I was given a better Lyriq as a loaner for a full month while the dealership was working with Detroit to get the car to charge again. The dealership said the propulsion battery seemed to be defective. Detroit finally sent out an ‘expert’ to verify what the dealership did and agreed that a new battery was required… The ‘expert’ came back to supervise the installation of the new battery and this incidentally required realignment of the ‘Super Cruise’ Radar. I figure that those 2 troubles cost GM about $25,000 since they could repair the old battery at their leisure, but with a month’s rental car, and the trips back and forth from Detroit of the ‘expert’, plus $200 / hour labor charge from the dealership I bet GM hopes not too much more goes wrong under warranty.

        Now, the car is in the dealership to handle an intermittent ‘Check Engine’ Light – which was brought on by a ‘Service Drive Module’ alarm (U1962). No electric rentals available this time so they gave me a 2024 brand new XT5 to drive in the interim..

        Other than that the only real objection to the car I have is the totally obtuse oversized touch screen. Sometimes it takes me 10 minutes to reset the trip odometer – its that bad.

        But overall, I like the car and the fact that I get about 330 miles between charges.

  3. I had heard that a Lyriq software update was coming in March for some time. The update mentioned above is for the 2023. Does that mean there is no current plan to update the 2024 Lyriq at this time, or not?

  4. OnStar told me a 2024my OTA is coming soon.

    Only issues I have is the center drawer sticks out 1/8” (replacement available) and sound(radio, phone) does not work sometimes. Need to turn car off and open/shut door to reset computer.

    Best car I have ever owned.

  5. When will the 2024 Acadia start production. No word since the March 4th date. Anxiously waiting a follow-up article.

  6. GM World Class tech here… ALL Lyriqs that come to dealership are required to have all modules checked for updates ANY time they are brought into the dealership for service. This includes any customer service visits and new car preps or PDI’s as they’re called.
    This can take anywhere from 2 or more hours depending on how many modules need to be updated.

    Reply
    1. Too much snapping of your suspenders Mr. World Class, as well as too much jargon. Such as what is a PDI?

      Knowing GM that can mean anything and change over time. But this mindset is the basic problem with my Lyriq and with GM vehicles lately. Overall reliability lately has only bettered JEEP, which is historically horrible.

      My car has had all its modules updated a few months ago, but the U1962 drive module fault keeps reappearing, even though only a RWD vehicle – only 1 motor. Issues here should have been eliminated back at the test bench, certainly not in finished vehicles released to customers.

      And who approved that almost useless obtuse dashboard?

      1. Sorry for your car troubles, but as I stated “new car preps or PDI’s as they’re called”.
        Also there are many updates even on vehicles that have only been in for service very recently. That is the mindset of doing the updates… hopefully to catch and improve any issues owners may have and resolve them before they occur.

        And I don’t wear suspenders….

        Reply
        1. Again, this is the problem…..
          GM only looks good in comparison with Jim Farley’s FORD, whose vehicles have the most recalls.

          No real sympathy for owner’s inconvenience I can tolerate, but GM sure ain’t making much money on me, what with the hugely expensive warranty work done on just ONE vehicle so far.

          Politically Incorrect Bob Lutz who therefore was forced out before his time, at least released a pretty flawless VOLT from day one.

          I suspect he is not missed but he should have been missed.

          And I couldn’t really recommend anyone buy a Blazer EV. If people there are paid $2 an hour to make it, you end up with a vehicle that seems like that’s all that it is finally worth. Even Toyota is having trouble, and FORDS made there are a basic joke.

  7. PDI= Pre Delivery Inspection.

    1. BV, yes. Apparently that guy struggles with reading comprehension, as I put my original statement in quotes to highlight it.
      And honestly, anyone who buys the first build of any new product HAS to anticipate issues that may take a while to resolve, ie; don’t they have beta testing for most new phone apps, etc?
      And I genuinely feel empathy for his situation but he just keeps railing about how bad the auto manufacturers are, knowing full well he could get a buyback on that particular vehicle.

      Reply
      1. Nothing wrong with my reading comprehension. PDI or preparation could have referred to different things…. When I write a paragraph I try to write as unambiguously as possible so there is only one way to interpret things – not several.

        I suppose it is just wishful thinking to hope that the engineers, and service technicians stop worrying about whether they are getting, in their minds, adequate applause, and instead worry more about releasing an expensive vehicle with problems that another group of people would have previously addressed.

        In my own case, the car was just given back to me after 6 days at the dealership. I looked through the repair order, and, while troubleshooting, they got that dreaded “SERVICE HIGH VOLTAGE SYSTEM” alarm which prohibits any kind of charging as I previously mentioned.

        The dealer told me, “IT WORRIES US TOO ! – A couple with a new LYRIQ up from North Carolina was in the same predicament and had to stay 2 additional weeks with relatives until their LYRIQ could be released and they be able to drive back home.”

        As far as a Buyback offer, none has been offered me, although it is getting to the point where Lemon Laws are likely to be triggered in NY State… The timeclock stopped with the battery replacement due to the dealership offering a vehicle to me at no charge which was at least as nice as mine, but ongoing troubles may still trigger things in the future.

        And if you don’t like my previous comments you are free to skip over them. A commenter here asked if there were any problems, and since this article dealt with 2023 model year issues, I just delineated mine… Most people would appreciate that and be a bit more contrite about it.
