So the charger could be having an issue - these have been reported to have some quality problems. But by chance - do you charge your Lyriq with a Schedule or Charge Later? If either of those, you may want to try 'Charge Now' and see if the problem goes away (after cycling the breaker again to correct). There is something about certain Lyriqs (seemingly newer software) that have been reported to make the charger unhappy with delayed charging. Not a clear solution yet if that is your problem, but something to try.

If you are using 'Charge Now' and you have this problem, something could be dying in the unit. If you are handy with electrical, you may also want to confirm that the power connections are tightened to proper specs, and not loosened up from use.

Don't try this is if you are not 100% comfortable around electrical connections, but I agree that this is something easy that can/should be double checked. These chargers pull a LOT more current than almost any other device in the house and need to have very tight connections in order to function properly.

 

According to the owners manual this is a "fatal" error and all use should be stopped and call the 800 number in the manual. They told me a periodic reset is OK but if it becomes frequent the unit s/b inspected for a loose dip switch or whatever. If you don't have your manual post back and I'll dig mine out for the number.

Fatal error of the installation of the wall charger or the Charger unit itself ?

 

Here's the manual.

 

Truth be told... and a little embarrassing - perhaps especially after just having done all of the electrical for our 400A service in our new home, but I made a mistake with the install of the "standard" Ultium 240v charger. After install, mine would blow the circuit breaker after about an hour of charging. When I reset the circuit breaker, I could feel that it was warmer than it should be. But, I reset it anyway thinking it was just an anomaly and, sure enough, it blew again the next time we were charging. Once again, the breaker itself was warm. On a whim, I decided to check the connections on the breaker and discovered that a screw for one of the load wires was not as tight as it should have been. I tightened it and that charger was good ever since. Again, DO NOT PLAY with your breakers unless you know what you are doing... but just saying that even a mildly loose connection at these current levels can cause excessive heat and overload protections to trigger.

 

This definitely happens, and no need to be embarrassed - and good to share your experience. Even the 'pros' can have these install issues, and as you say - a much bigger issue at the 48A which a standard Lyriq can draw (not to mention the 80A option).

A thermal camera or even the iPhone accessory is a good thing to have if you are doing high current electrical work. The "trust but verify" approach. Even with someone like Qmerit, they don't test the system under load for a period of time. I think it should be standard practice to test the EV circuit at the rated load for an hour and check temperature of both the breakers and the termination (EVSE or outlet). But that would require having an EV or high power test load (and time), and they always seem to be in a hurry to get to the next job.

 

Seems, the Electrician is going to charge $150, if the unit is at fault and nothing if the installation is at fault.

Did anybody had this issue of "Red Light on the Charger issue" and what was the outcome ? Like installation issue or the charger fault.

My charger is still under warranty but GM doesn't look like to help in this matter.

 

Have you contacted EV Concierge phone line? I called them and on a follow up call they bridged in a CTEK (manufacturer) representative who then authorized swapping for a new charger. In my case it was a charger fault.

 

If you have access to an infrared detection device then check where the wires connect to the circuit breaker and to your EV charger to make sure that there is not a high resistance connection. You might consider removing the EV charger cover and check inside the unit with the IR device. Use caution as 240 volts should not be considered lightly.

 

I have zero knowledge of the electric connections and no devices to perform any kind of testing.

 

I had similar issue and the red light would come on at start of chargning or when unplugging it after charging. The only way to get rid of it was by turning the breaker off and on. I have plug in set up so removal/reinstall was easy, took it to dealer and got a brand new replacement unit. Any Cadillac dealer should be able to give you a replacement unit so you don't have to go to the selling dealer.

 

I went to dealership with the defective charger, which they checked, and replaced with a new one. They obviously had a new unit on hand. The new one has worked flawlessly since.

 

BTW the car was at the dealership last week when they fixed the super cruise.

 

I had a Level 2 charger already installed at home, for the other EV we bought several months before, so I've never even taken my Cadillac charger out of the wrapper. All this is making me wonder if I ought to pull it out and test it, just to make sure it works before I get out someplace and need it.

 

Level 1 seems ok without issue - either 8A or 12A. Level 2 is the wildcard - I have wondered the same. Would be nice if GM would allow us to de-rate lower than 32A - would be helpful as a workaround should the problem occur.

 

I have started having the solid red light issue on my standard Ultium PowerUp (hardwired) charger after over a year of great service. It's now happening at least once a week. Nearly always occurs near the end of the charge cycle, and often causes the car to start beeping loudly (presumably because the charger stopped delivering power unexpectedly). Flipping the (60A) breaker off, then back on again fixes it until next time. This has been occurring more and more frequently. Lug nuts for the wires have been checked to ensure they are still snug, etc.

Finally called the EV concierge - they are looping in CTEK.

To be honest, if they swap it for a new one - I'll likely sell the new one and get something else. Very disappointed with the fact that we never really got any software for this even though it's WiFi/internet connected. The app is basically useless. I would love to be able to track energy usage, etc. Might splurge and get the Unifi model - it's pretty neat and would integrate well with the rest of my network.

I'll report back with what happens.

Sorry to hear this. I know a lot of people had this same issue, but it seemed you were spared. 6-12 months seems to be the timeframe they work and then die.

As you did the install yourself and are comfortable with this, you may want to just check the terminals. There was the early problem with the units not being able to have the terminal torqued properly, which resulted in a stop sale for awhile. Perhaps you can pull out the wires and look for oxidation or carbon build up, and re-torque and see if it fixes it. I know you said they were snug, but there are levels of snug - and removing and re-torquing is different than just a pull test. If that doesn't change anything, then we'll know it is some other design issue.

 

Thanks, while I didn't remove the wires, I did put my wrench back on them and made sure they were torqued. I did not use their included tool as it didn't allow for proper torque. They were well torqued. Visually the wires look brand new. This is inside in a climate controlled garage. I guess I could pull the wires out but judging by the shiny copper I could see, I think they are good. Good suggestions though.

I'm guessing it's just another defective unit.

 

Sometimes it is a dissimilar metal reaction - where removing and re-torquing can help.

Well maybe give it a go if you have time - nothing to lose. Of course, with the power off.

 

Heard back from CTEK:

Due to the frequent recurrence of the fault described, I believe the internal current-monitoring device (similar to a GFCI) is failing and giving false-positive faults. I am recommending replacement for this charger.

Please assist the customer with the replacement process.

So far no word back from the EV Concierge

I recommend reaching out to EV concierge. The resolution for me was that EV concierge contacted the dealer of my choice to approve the swap. Oddly the process at my dealer required the service and parts department to be involved. Once everyone was in sync and a new one was in stock at the dealer, I had to take the old one to the service department who then went to the parts department to do the swap. I was told I could leave the mounting bracket on the wall. I returned the main unit, the cables and the locking key bit. They gave me everything new in return.

 

I would highly recommend anyone who is considering what EVSE to get to get the Tesla Universal Wall Connector. It comes with CCS/Nacs adaptor included, 4 year warranty, you can schedule things from the app, the cable is much easier to work with and you won't have to worry about future compatibility when everyone switches to Nacs 2-3 years from now.

 

Seconded. Had mine installed beginning of the year and it has been great. The built in adapter making it a streamlined futureproof EVSE was what sold me.

 

EV concierge did follow up. Basically just go to the dealer of my choice and they will swap it. Called my dealer, they are suppose to call me back Monday. They are supposed to have two in stock but he couldn't lay hands on them. He seemed very willing to make the swap though.

 

The timing of this thread resurfacing is uncanny. I have the 19.2 kw charger that was replaced about 6 months ago due to the red light error. Apparently this a circuit breaker that burns out and they claimed to have fixed it in updated models.

This weekend I went out to my garage expecting a charged car, as scheduled. Instead, I saw the familiar solid red light and that the car was not charged. I reset the circuit and it began working. Hoping it was a fluke and doesn't start happening more frequently like the last unit.

 

For those of you with the Tesla UWC do you get an error when starting the charge or has that been fixed in updates? I recall reading that there is a handshake issue with non Tesla vehicles. I like the looks and reputation of the Tesla but this error, if it exists, might make the wife unhappy with that choice.

 

Tesla has 2 kinds of wall connectors. One is universal (dual nacs/ccs) and the other is for tesla vehicles.

I have had no problems using the Lyriq with the Tesla Universal Wall Connector. No errors or even had shake issues. It always goes green.

You can also use the tesla specific wall connector with the Lyriq (but buying your own ccs adapter). This one usually has handshake issues but charges anyway according to reports.

Just stick to the universal one and it should work fine

 

Parts dept at local dealer called, they will have to order - could be a week. Said I couldn't just swap it - would have to make appointment with service dept so they can 'test' it.

Called the service dept, he was like - uh, yeah, no - i just need to write up what is wrong with it - no appointment or testing needed. I told him I could print out the email from CTEK - he said that would be perfect.

So now just need to wait for the call from Parts dept. Meanwhile it's now doing the red light thing on nearly every charge.

Honestly - I'm over this charger. They never gave us jack on the app. Trying to remember what all the status bar lights on the front of it is annoying. And this one lasted 18 months. 3 year warranty, so assuming the warranty doesn't reset (doubt it), then I could be out of warranty next time. It's a shame because the build quality is excellent. I will sell the new one. I've ordered something else.

Stay tuned for a review of that.

 

Working on a follow up review video of the Ultium PowerUp charger that I promised would come 18 months ago...and of course NOW the stupid thing won't do the red light error and is working perfectly because I want to film it. 🤦‍♂️

In other news the new Ubiquiti EVSE arrives today. Hope to install this weekend. 🤓

 

Apparently I cannot win.

Probably should have picked a tried and true EVSE.... 🤦‍♂️

The Ubiquiti EVSE is amazing in many aspects, but day one having an issue: the charger absolutely refuses to listen to the car when it's done charging. I mean the charger stops delivering power....but the screen continues to say charging and the counter continues to count away. Only way to get it to stop is unplug it from the car. If you plug it into the car when it's full it shows 'charging' again, counter starts counting away again, will do this forever with zero kw delivered.

I've opened a ticket, we'll see. I definitely didn't spend this kinda money to be a beta tester.

I've filmed a lot of footage and plan to make a video regardless, but I want to see how this plays out first...

 

I just noticed my new error is different than my original unit. The original unit had a solid red light - fatal error. This new one is giving me a blinking red light that can be reset just by replugging the car in. Manual says it is a resettable error but it seems I need to reset it at least once a week by reseating the car plug. Its definitely different than the solid red light which needed the breaker flipped to reset. I wonder... anyone here know the cause of this new fault?

 

I'm seeing this as well. Not sure if this is an EVSE problem or something caused by the momentary power blips my house is having due to weather. I've sometimes seen it at the start of sessions and also at least once after a successfully completed charge with the car still plugged in.

 

Started happening this month and I replaced my charger back around beginning of March. Pretty similar timeframes.

 

Interesting...It's a big jump but I wonder if there was an update to the charger firmware that is making it overly sensitive to something. Is yours connected to WiFi?

 

Mine was exchanged at the dealer this week. Pretty simple process, got a new one sealed in the box. That one has already been sold. After the short ownership of the mess that is the Unifi charger (video coming soon), I'm REALLY enjoying the ChargePoint Home Flex. The app is REALLY good, and I love the daily graph showing me how much it each session cost based on my home energy rates. SUCH a step up from the Ultium EVSE. Sad really. I'm usually first party accessories only, but they really dropped the ball on the Ultium charger.

 

My Ultium PowerUp hardwired 11.5 kW charge was installed in March, 2024. I stopped using it a few months ago - but left it on. No problems. For a few months I used the portable charger that came with my Lyriq. A couple of weeks ago I put the portable charger away and started using the PowerUp charger again - but this time, I reduced the power going to the car to 15 amps.

Last week, the car was plugged in, I heard a series of 3 beeps from the garage. I found the red light on in the left corner and the car not charging. I unplugged the charger from the car and turned off the breaker. About three hours later, I turned on the breaker. The charger looked stable, so I plugged in the car. Charging resumed. Two days later, the three beeps started again, I unplugged again, turned off the breaker, waited a few hours, plugged back in and all has been fine since… with one new thing introduced. I had been using the charge later schedule (start at 9:30 pm, end by 10am) and always set to 80% at home, but yesterday when I got into the car, charging was at 91% and had not turned off. I found that Charge Now was active, so the scheduled charge later schedule was not being used. I re-engaged charge later, made sure the schedule was being used and the charger was set to the 15 amp reduced charge rate (it was). All has been fine for a couple of days.

It seems odd that whatever did this could cause the charge later schedule to stop being used, but allow the 15% display light amount set by the app to remain.

Any thoughts? Is this the start of the charger failing or is it possible some sort of power anomaly occurred 2x and the charger is actually OK.

From my and other people's experiences this is the start of failing. You can try one or two more times and see if it does the same thing. Then call Cadillac concierge to start the exchange process. They will contact CTEK for diagnosis/approval , then your dealer of choice to start the exchange.

 

Update:

The QMerit process = I pay the contracted electrician $200-$300 for each site visit. GM funds “up to $100” per site visit.

The process means I take the no longer-in-use “hazardous, defective, charger” to the Dealer that wants to charge me a $160 restocking fee for something they are not restocking.

This is for a GM Ultium Level 2 charger that is under 3 year warranty. And up to now, the Concierge has claimed there is a (too late for me) “extended service contract” mentioned by my Concierge contact that would have taken care of most of these additional expenses… which I was never offered during the acquisition process… and which, so far, the Concierge has not provided or told me how much that would have cost when I might have qualified.

All I want now is a full refund of the charger purchase. At first, a replacement was on the table. But the Concierge did a fine job of flipping me to getting out of that and if I never have to deal with the Concierge, GM Ultium or GM Power that would be just fine.

I still want to love the car and I just can’t. A huge part of the “Cadillac Experience” is the service. This whole series of events for the past 6+ weeks is so far from that.

I wasn’t treated nearly so poorly in the prior 3 Cadillacs and 3 Chevrolets we’ve purchased over the last many years. From my perspective and experience with this Lyriq, associated parts/accessories and their related web sites, GM and Cadillac are very seriously broken.

I am envious of those who have not had GM/Cadillac issues with their vehicles, parts or accessories… I used to be there and it was great. Now? Much worse than “not so great”.

After 40 years in customer support, I know to cut the customer facing folks some slack… but GM/Cadillac has, for me, made that difficult, frustrating and disappointing.
