Some 2023 Cadillac Lyriq Units Require A High-Voltage Harness Fix

The Cadillac Lyriq is a very important vehicle, not just for Cadillac, but for GM as a whole, launching the luxury marque’s first production all-electric product and moving General Motors towards its goal of achieving zero tailpipe emissions across its light-duty vehicle lineup by 2035. Critically, some units of the 2023 Cadillac Lyriq may require a fix for the high-voltage harness, which could rub against the high-voltage battery case, causing damage. Now, GM has issued a service update for affected models.

The front end of the all-electric Cadillac Lyriq.

The new service update only applies to the 2023 Cadillac Lyriq, and includes both customer vehicles and vehicles in dealer inventory. The issue pertains to the crossover’s high-voltage harness, which may be damaged when it comes in contact with a sharp edge on the high-voltage battery case. It’s unclear exactly how many units of the 2023 Cadillac Lyriq may be affected by this issue.

In order to fix the issue, GM is instructing certified GM technicians to apply an “anti-abrasion electrical tape / orange electrical tape” to secure the high voltage harness away from the high voltage battery case. The fix may also require a wire tie-strap. The fix may only be completed at a Cadillac dealer that has met the EV Readiness Requirements, while the technician who performs the fix must have successfully completed all required training.

As GM Authority covered previously, more than 2,000 units of the Cadillac Lyriq have been produced so far during the course of the 2023 calendar year, while deliveries to customers continue to accelerate. It’s estimated that roughly 1,000 units of the Cadillac Lyriq were shipped during the mid-January to mid-February timeframe. Additionally, just 122 Cadillac Lyriq units were delivered during the 2022 calendar year.

For those who may be unaware, the Cadillac Lyriq features GM Ultium batteries and GM Ultium Drive motors, with the GM BEV3 platform providing the underpinnings. Production takes place at the GM Spring Hill plant in Tennessee.

  1. A fix already?

    1. Sounds like a homeowner that works on their own cars could easily do this one themselves rather than waste time at a dealership. I hate having anyone work on my cars nowadays because it seems there is always another paint scratch or mark on my cars that I didn’t notice or see before taking it in. Newer auto technicians / mechanics don’t seem to care about the owner’s vehicle like they did in the past when working on the outside parts of the cars..and they will probably need to work over the front fenders of your new car to perform this fix.

  2. Already started. Lyriq is almost a hand built car and GM still cannot get it right. No excuse. If this nonsense is allowed to happen, even seldom, GM will not be the the EV business long.

    1. The Lyriq is as “hand built” as the XT6, XT5, and Acadias running down the same line. When the vehicle gets to my job I have about 48 seconds to install my parts and the on to the next car.

      1. Thank you for adding a real comment based on experience versus the armchair quarterback.

        Something being built with lower output doesn’t mean it can’t be built faster. I assume it’s parts availability slowing it down? I know it currently can’t be ordered with SuperCruise.

      2. Jeremy:

        I’m no auto production engineer, but why would an EV be made on the same assembly line as ICE vehicles? Is that part of the volume problem?

        To ultimately get the cost/car down (and profits up) is going to require new approaches to both design and production. Tesla has obsessively attacked the entire process and now has the lowest cost per car of any manufacturer to the point where they were able to drop prices up to five times since January, effectively starting a price war.

        GM is early in the EV learning curve, but Tesla was an absolute newbie to making cars when they started ten years ago, while GM has been a car company for over 100 years.

        Parts constraints must be an issue, otherwise why is Cadillac not running a dedicated line for the Lyriq? There are certainly enough orders to keep two shifts going to eliminate the backlog. Getting cars on the street will give a return on investment for all that $$$ advertising they did last winter.

        1. They are very similar outside of the battery installation. The motors/drivetrain/invertor are preassembled. Bodies, interiors, suspensions, wheels, and brakes are all the same.

          The main cost savings in EVs is the motor and drivetrain versus ICE and its multispeed transmission. Electric motors and drivetrains are magnitudes simpler than their ICE counterparts. Granted the expense of EVs is their batteries.

          On your note about Tesla, they make two cars in volume and one is a derivative of the other. Tesla’s model doesn’t scale well when you’re a full-line manufacturer. They are running into a problem now with the S and X. They don’t sell enough of them to keep the lines going efficiently. Legacy manufacturers would just flex the lines to build different ratios of vehicles.

          GM’s plan will be to just make more and more EVs in the plant as they fade out ICE vehicles and bring other EVs into the plant.

    2. I reserved a 2023 debut edition in May 2022. I expected delivery in July 2022, then every month after that. In February 2023, my dealer gave me my Lyriq’s VIN and said it was “in transit”. Fast forward to June 2023 and my car is still sitting in Springhill, TN. I am pretty sure that Cadillac will start delivering 2024 models before my “Debut Edition” makes it on a train.

  3. Seems GM just cannot get their build quality where it needs to be. Thought maybe EVs would be a fresh start but so far no go.

  4. These are 23 Models. These vehicles are the first and all the issues are being found with it before the Full production starts with 24 models.

    You cannot predict everything… It takes actually being built then time in the real world before issues are found.

    I’d be more upset if the issues were found and not addressed…
    GM is being proactive here in resolving found issues.

  5. A dud on arrival

  6. I am truly astonished that GM is having so many issues bringing the Lyriq into production. At least they are not like MIcrosoft who lets their customers deal with all the initial bugs.

    Reply
  7. I think people don’t understand the reason for the Hummer and Lyriq EVs. They were initial test beds for GM EV trucks and CUVs. It allowed GM to test the components in a lot smaller audience. The issues that have been found with these vehicles are relatively small and the number of vehicles in public hands is in the thousands. Imagine if this was the Silverado, Blazer, or Equinox EVs that will be in a lot more hands.

    I don’t hear anyone complaining that actually have these vehicles because they like them.

  8. RE: production numbers.

    Mr. Lopez writes, “ As GM Authority covered previously, more than 2,000 units of the Cadillac Lyriq have been produced so far during the course of the 2023 calendar year, while deliveries to customers continue to accelerate. It’s estimated that roughly 1,000 units of the Cadillac Lyriq were shipped during the mid-January to mid-February timeframe.”

    As written, this means that 1000 units were produced mid January to mid February (~30 days) Then the YTD total is 2,000. Subtract the initial 1,000 from the 2,000 and you get 1,000 produced mid February to mid May (~90 days). Even if you allow time to switch model production years, this is still less units per day than at the start of the year.

    How does this align with the later statement that, “ deliveries to customers continue to accelerate”? The provided data says that production has decelerated, not accelerated!

    Is this a case of poor production data, lack of fact checking, poor writing, or more BS from GM?

    Reply
    1. Poor writing and also Production =/ deliveries

      Lyriq had several vehicles on production hold/Quality Check and slow rolled their deliveries.
      Now as production neared the end of the 23 Run and start of 24, owners saw their vehicles being produced and delivered with in weeks rather than months that others had experienced earlier.

      1. Meep:

        The announced production numbers have been all over the place. First it was several thousand produced but not delivered in Q4-2022. Yes, Cadillac held them because of unannounced, even to their dealers, reasons. Eventually, they had to admit that the slow rollout was due to “production problems” and “wanting to make sure they delivered a quality product “. Yeah, right. It had nothing to do with covering their corporate butt.

        It would seem to me that a better way would have been to announce WHY they were holding the cars so people who put down an admittedly small deposit would know why it was taking so much time… like Tesla did.

        The few who have taken delivery and have announced it here, say their VINs are in the 3000’s so where did those cars that were produced in 2022 eventually go and when? Likely it was a combination of mid January to mid February production and the 2022 DE cars that readers here have been receiving.

        So where does that leave those who are still on a waiting list that only Cadillac knows how long it is, with according to forum posts people have stopped waiting and purchased a Tesla or Ionic 5?

        I’m sorry to say if Cadillac said the sun was going to rise tomorrow, I would not believe it. I will continue to wait for the Lyriq I have ordered, but this will be the last GM product I will buy. If Cadillac is going to ask upwards of $70,000 of my money, they can, at the very least, treat me as a respected customer.

  9. I want to change my 2024 order to a Lyriq-V. How soon can I? Will an opening sunroof be available on it? Chicago pot holes are murder on low profile tires. Can the -V version be ordered with standard wheenls and tires?

    Don’t sweat the critism about slow production ramp-up. You are fixinging the glitches instead of wasting the time of your customers.

  10. Hmm.. my gas inlet is nearly 30 years old never had a problem with it.

  11. The Hummer and Lyriq are expensive Beta vehicles for early-adopters. Packed full of GM’s newest stuff.
    If you buy one you should understand that.
    Unfortunately for GM, luxury vehicle buyers are a picky bunch. 🙂

    1. Thanks for your comment, Garo.
      We will put you down as a Tesla hater on our GM Authority mailing list.

    2. Yes but they have produced and delivered hundreds of thousands of vehicles. You see a lot more Teslas on the road versus GM EV vehicles.

  13. Garo, that is very true. Ford won the EV truck war, have sold thousands, and are testing the next generation of Lightnings, plus they will soon annonce the second EV truck, probably the EV Ranger.

    Reply
    1. The EV truck war hasn’t even started yet. The number of EV trucks being sold is a rounding error to the overall truck sales.

  14. Costs to produce will be an issue for success. Detroit has handicaps of UAW wages, benefits, and the legacy cost of UAW retirees. So they must get the QRD right. Tesla needs to get better at interiors, fit and finish. Startups are the underdogs. Foreign manufacturers, with their non-union plants in the US, have the pole position.

  15. Tesla had far more problems with the Model 3. When it came out the bumpers were falling off and the doors did not align. People could not even get out of the back seat.

  16. What I want to know is when I can expect my AWD (ordered last year with 1K put down inside dealership with signed contract) to be delivered. Since the 2023 was now changed to a 2024 it would be nice to know if this is just kicking the can down the road with no real estimate of an actual production year. Since no one is being given numbers there is no way a customer can even guess at when their vehicle may be produced. If there are 20K orders ahead of mine I would drop out immediately and purchase another vehicle instead of waiting 2 or 3 years. The price of vehicles will continue to rise and there is no lock in price even for 2023 orders once this production year ends. My contract had a fixed final price so I am waiting to see what really happens with that but after the 2024 production year I will bet all those “5K subsidies” are voided if they really even show up as promised.

    Since GM dealerships are able to give a fairly accurate time frame of when a dealer placed order for a C8 corvette will be built, there is no reason Cadillac can’t give a similar prediction for customer orders. I’m not even talking about a predicted monthly build date (as for the C8) but just a predicted year for the build of the Lyriq. This crap about ramping up production is meaningless without the number of system orders to make a determination.

    Maybe it will take federal action to get this info from GM. It just seems that customers should be given an expected time frame so that they are not strung along a year to two (or three) waiting for a vehicle when they could purchase a rival vehicle in just a few nmoths. C8 owners are told their time frame (and it is fairly accurate) and they can decide to sit and wait or jump ship. With the Lyriq it is purely a guessing game with no numbers to make a reasonable decision.

    And I agree with the comments that GM should already have a separate EV assembly line built by now just like their corvette line. They had more than enough time to have one built watching their rival Telsa build theirs. Presonally I don’t think Ford or GM will ever catch up to Tesla now since they wasted too much time with their slow pace. Tesla will slowly improve their quality as their production rates increase.

    1. You are exactly right, PWD.

      All customers want is HONEST information. We CAN deal with the truth.

      Tell us what is going on, why and what your best guess is for a real delivery date, so we can get on with life.

      I can wait until my ordered car arrives, but I’m over the income cutoff to receive the federal tax credit. I can, but would hate to leave $7K on the table. However, by accelerating some expenses and charitable giving into this year and pushing some income into next year, I can qualify. However, all that has to be completed by mid November so all the checks clear and it would be difficult to do the following year.

      I just need “reasonable” assurance that the car will be delivered before then. Is that too much to ask for an order that was placed in May of 2022?

      If it won’t be delivered until Q1-2024, just be honest, stop stringing me along and tell me!
