The SoC dropped from 94% to 89% last night. Car was plugged in with timed charging selected for later this afternoon. I did have a departure set for 9:00AM to keep timed charging active. I forgot to turn it off but I am concerned that a forgotten departure would drain the battery by 5% while plugged in.

The hazard button was illuminated well after the departure time ended. I unplugged the car and cycled the door locks and the hazard button is now dark. Any ideas as to the sudden battery drain?

Was the outside temp really high and the car was running the AC to get to / keep the climate control at the desired temp?

Temp inside the garage was probably in the mid to upper 80's. AC probably ran but would the power drain be higher than what the level 2 charger could replace? Or would it not replace at all due to timed charging? I've previously used departures and lost perhaps 1% but I was on time getting into the car.

My other question is, how long will the departure cycle run after the set time? Good experiment for me to try, I guess.

I'd definitely be interested to know those things as well. I haven't had to use them much at this point (because I don't drive enough to need to charge through the week, and our ToU is 8pm Fri - 8am Mon), but if I do and then end up changing my plans it would be nice to know if that will really deplete things.

I'll do the experiment today and will post the results.

Conditions were set exactly as the 9:00AM departure. Car was plugged in with future timed charging set and target temperature set at 72°. Garage temp was 79°. Incontrol app showed climate control running at 30 minutes prior to departure but car was silent and only the Max Defrost button flashing - no cabin air flow. At 15 minutes prior to departure the air flow started but the AC button was dark so I don't know if it was running. Car shut down 10 minutes after scheduled departure. SoC dropped only 1% and hazard button was not illuminated.

I can't explain either the 5% drop from earlier this morning or the illuminated hazard button. Perhaps something hung up on vehicle shutdown. But I did learn that the vehicle shuts down 10 minutes after the scheduled departure time.

I will try the procedure again with vehicle unplugged to see if there's a greater loss of SoC.

Same departure procedure with car unplugged. Garage temp was 90%. Car shut down at the scheduled departure time vice 10 minutes later when car was plugged. Of interest, the SoC before departure was 88% and ended at 88%.

Still unexplained is the 5% loss from morning departure.

Whatever caused that illuminated hazard button also most likely caused the battery drain. The dealer should be able to retrieve a fault code next time you're there.

Hazard button illuminated well after the car should be asleep indicates the car isn't sleeping and it will drain the battery much faster than normal in that state. My hazard button stayed on for 7 days when I had the blank screen issue. In that state, it drained the battery much faster than normal when parked and locked. The I-Pace has no shortage of software gremlins. It's a shame because its such a great car otherwise. I'm still hopeful JLR will manage to remove their heads from their rumps at some point and straighten these things out but they are certainly trying our collective patience.

Did JLR fix your blank screen problem? I had the same issue and a software update fixed it. The car is doing much better and was fine last night - no battery drain. It was probably something related to the car awaking for the departure time and then not shutting down properly. I will bring it to the dealer and find out what happened.

I so agree if JLR could fix these gremlins that the car would be fantastic. I still have adaptive cruise control and blind spot monitoring issues that make the car unsafe if I use them. I'm unsure if software can fix them.

Nope. My screens were blank for 7 days. The screens woke up on the way to the dealer for the service appointment. My dealer said the car didn't report any fault codes so they wouldn't do anything about it. They wouldn't even acknowledge that this is a common problem. They told me there is no material from JLR corporate distributed to service departments on the issue. As reported on forums, Telematics version 16.2 might actually fix the issue, but my dealer refuses to acknowledge the existence of any version beyond the 14.2 my car has. They tell me my car's modules all have the latest software versions, but I know the only two modules I can tell the version of (telematics and infotainment) both have newer versions available. I just laugh and keep enjoying the car. SOTA will hopefully resolve this situation soon.



Do you know what they updated on yours to resolve the problem?


The sucks about your blind spot and ACC troubles. Both of those systems work pretty well on mine. Like you said, that probably isn't a software issue. I hope you manage to get those resolved because they are both quite useful.

Sorry to read about your dealer. It's unacceptable that they refuse to admit that there is a known issue with the touchscreens after the 19A update. There is new software as discussed in this forum and someone posted a Topix bulletin that describes the touchscreen issue in detail. I'll track it down for you.

My screens were fixed by a telematics update but neither the car nor the paperwork list the version. The screens are much more stable and only seem to boot slowly when my grandkids are in the car. It HAS to be their fault, eh?

I recommend you contact either another dealer or JLR directly and have them call the offending dealer.

I will bring the car in for service again as the SoC dropped last night and the hazard button is illuminated 12 hours after shut down. Since the initial 5% drop the SoC has dropped slightly (1%-2%) three times but I dismissed it as normal. Now I'm seeing a trend and need to find out why.

It's frustrating because I took the car for a long country drive and everything worked well.

Juice, please see post 21 of this link as it has the Topix memorandum regarding the blank touchscreen issue.
Thanks for the info, but the PDF in that post is not from JLR and none of the steps described there worked for me when the screens were blank. It only happened to my car once in 6 months of ownership and over 6000 miles of use. I'd rather chance having the problem again instead of wasting time fighting with my dealer which isn't likely to help anyway. I'm not mad at the dealer. They are nice people and try to be helpful. It's an annoying problem, but the car still drives fine. Yours sounds much more severe and I probably wouldn't be as cavalier about it if it happened to mine as frequently as it seems to be happening to yours.

Ugh. Good luck.
I don't know if it was a coincidence, but when my screens woke up both key fobs were in the car. The one I normally use has a profile tied to it and with both key fobs in the car, it may not have been able to decide which profile to use and that may have woken up the screens. So, you might try using the other key fob and see if that wakes it up. Again, this only happened to my car once, but the screens were dead for 7 days and they woke up within minutes of both key fobs entering the car. The screens didn't wake up immediately, it took a few minutes of driving before they woke up.

Thanks, Juice. Telematics update fixed the touchscreens and the update to 19A solved many of the infotainment issues. All that's remaining to fix is the battery drain problem. Oh, the dealer also needs to tow the loaner Discovery Sport that's broken down in my driveway. I've lost faith in any JLR product.

I picked up the car after 6 days at the dealer and they couldn't reproduce the problem. There were no fault codes from the 5 or 6 times that the hazard button remained illuminated and the battery drained while parked overnight. I'm disappointed that they couldn't determine a cause but that's the nature of intermittent faults.
