Hi,

This morning I got into the car while running errands (so the 5th time I started the car today), I got a message indicating an issue with the stability system, (sorry, did not write the message down). It displayed the yellow info icon and the red alert icon and the yellow turtle icon (and said it was ok to drive). I was a few blocks from home, so I decided to drive with "reduced performance" as it said. Right away I felt a pronounced pulsing from the front wheels (I think the left front) so I went right back into a parking space (I drove maybe 30 feet). I tried reversing a bit into the empty spot behind me and forward again (so always in a parking lane) and the issue persisted. Tried turning off the stability system, and restarting the car a few times with no improvement. Finally called the roadside assistance for a tow. They said it would be an hour, so I walked home with perishable groceries and came back to the car 30 or so min later. I started the car and the error had gone away. When tor tow truck arrived, I decided to see if the car would drive and it seemed fine. I cancelled the tow and drove home. Did 2 test drives and no issues. I plan on driving to the dealer Monday but has anyone seen this before?

Scary story! Do you plan to call your service department?

I’ll call Monday. Hopefully they will be open. Lots of businesses are closing due to the Coronavirus. Hopefully they will keep service open.

Best of luck. Fortunately the car is driveable but I don't know if I would trust it.

For anyone reading this and having issues, like this or any other that lights up the instrument panel with warnings, if it all possible have the vehicle towed to the nearest dealership right then. Repeated starts and driving attempts may clear the fault information and the dealer will say "we don't find anything wrong." It is most helpful to diagnose a problem while it is still fresh in the cars memory.

Some faults, if a transient condition, will clear if the car is started and driven 4 or more times without sensing the problem. However, it may recur at the most inconvenient time and that time it may not clear by itself.

I know how tempting it is to keep trying and hoping it will return to normal. It is what we used to do pre-computer controlled cars.

Aside: The closest dealer to me was closed one day this week when I happened to stop by to schedule H280 update. It had a cleaning crew there. It now has signs up saying that "this is a no handshake building."

I figured the logs should keep any faults? That would be pretty basic to maintain a log file in an embedded system (Unix or QNX). I wanted to avoid the embarrassment (and potential for scratches etc...) of being towed. If it happens again before Monday, I can always get towed and I was not planning on going anywhere far. I just got back from a long trip (literally yesterday) so I am glad this did not happen on the road.

Ayepace is right on. We keep getting a check engine light on a 2004 WRX and by the time we get an appointment the codes have cleared. Finally ran straight to an auto parts store and they were able to get the code.

I had an interesting experience a few min ago on my drive home. I floored it at a stop light but the surface was uneven .. the car went into a bit of a side to side and I had to countersteer quickly. At the next light, with admittedly less uneven surface, I turned off the DSC and it didn't do anything like that. I wonder if the DSC goes wonky sometimes.

OK, so after 8 months, the problem reared its ugly head again. Exactly the same issue. Pulling out at a green light and I get the turtle screen, drive with reduced performance message, followed by the stability system failure message and the same severe pulsing from the brakes as I tried to move forward. I was on a commercial with parking next to me, so I pulled in and parked. Tried restarting but still happening. Given it ia a Tuesday (last time was a Sat morning and I was not keen on losing the car all weekend), I opted to not wait it out (it magically cleared the last time after sitting for an hour) and get Had roadside assistance to tow it to the dealer.

It is there now and it had already healed before getting of the flatbed. Hopefully there will still be an error code to read, otherwise, they will likely not be able to repro and find the issue. Anyone else experience this since the topic was last brought up?

I got a Chevrolet Trax as loaner!

Arg, Bummer!!!
Might it be related to battery temperature? What if your battery was super cold (you're in Canada after all, haha) and you tried to pull too much power?
Regardless of actual cause, there's clearly something wrong ... I keep fingers crossed they find something 🍺

Hi,

It is relatively warm these days, so I don't think temps are related. I also don't think this is related to anything EV specific. I was not accelerating hard and once it happens, then getting above a few mph triggers it regardless of how slowly I accelerate.

I'll give an update once I hear back from the dealer, but given the error already cleared itself, I doubt they will be able to repro.

Got the car back today. They replaced and ECU in the anti-lock system and updated a ton of software modules. Hopefully we'll not see this re-occur.

I got these messages on Sat 7/3/2021. I have just over 2100 miles on mine and I don’t drive it much. I got the car on 10/31/2020. First instance was last week 6/27/2021. Just like some of the others it was not my first trip of the day on the 27th when it happened. On July 3 when it happened it was my third trip of the day. On 27th I had the rear wheels bucking violently until I pulled into a parking spot at slow speed. Normal driving speeds when the warning came on were no problem. I called my local Jaguar dealership to set an appointment on July 3 and they said they were all booked up until July 21 at the soonest. Is this normal? Usually when I’ve booked with other brands in the past, I could make an appointment and get a loaner same day.

Update 7/28/2021:
Dropped off my Cat at the local JLR service Dept for the first time on 7/21 last week. I made an appt back on 7/3 and had to wait that long to bring it in so I could get a loaner.
They gave me a 2021 Disco Sport $46K base and $57K+ with options. My first time driving one and the first ICE car I’ve driven in months. My first thought was, “why doesn’t it move when I press the accelerator?” Then I thought, “why isn’t it slowing down when I take my foot off of the accelerator?” Final thought: driving EVs only spoils you.

I called the service Dept today and they informed me that:
-they updated the software but didn’t find any outstanding campaigns or see any faults.
-they drove it last week ( I checked the app.) and experienced the same issue as me; traction control off, brakes engaging/pulsing, warning signs, etc.
- They determined that my front motor and back motor are going different speeds. They ordered a new front motor and it should arrive Friday. They also said they have to order a new high voltage wiring harness from there UK and that will take a few more weeks.

Is this the wiring harness issue that affected 1st year and earlier 2nd year models?

I honestly don’t know. When I tried to ask for more details, my service advisor was reluctant to give them to me, stating that the detailed report will come from the service mechanics when the job is done. I asked for an email so I can know what’s going on so I could have a record of our conversation. I haven’t received it yet. I can look up my build date later for you to see if it falls in the range you are mentioning. Mine is a 2020 model.

*8/13 update:
Got a call from my Service Dept letting me know that the new front motor and wiring harness had arrived. When they opened the crate for the new motor, it was damaged. They don’t know where they will be able to source another one from.

I asked if this continues, beyond a reasonable amount of time, if there was a way to get payment deferrals or gas reimbursement because I paid for an $81K EV and now I have a fuel bill that I did not account for when I purchased my vehicle. They have given me a loaded Disco sport to drive but it’s still not the car I purchased. Is this too much? I understand that I am lucky to have gotten a loaner in the current climate, but I also feel that I purchased a Jaguar EV for a number of reasons; one of which being not to pay for gas anymore.

I understand where you are coming from. You just want to drive the car you bought. I wonder if it is worth a shot to replace the wiring harness and see if that fixes your issue while you wait for the new motor? Not sure the harness would affect the motor speed difference issue, but hey maybe it's worth a shot.

As far as the gas goes, you do have a pretty nice loaner and the miles you put on the loaner presumably mean less miles on the I-Pace from a wear and tear perspective. From a strictly money perspective, the reimbursement rate per mile on a vehicle is $0.56/mile for business related travel. If you look at that as a savings on not driving your I-Pace, it adds up pretty quickly if you drive much. Again, I understand your desire to just have your I-Pace back. Maybe this information makes you feel a little better about buying the gas, maybe not.

Good luck in either case!

Your issue sounds a lot like the harness issue (I had that back in Jan 2020) and not the motor. More recently I had mine in for few weeks for the on board charger and had an F-Pace the whole time and thought it was a crime to out 4cyl engine in something that big. Almost had to plan passing a car a day in advance.

Thanks!
I will let my service advisor know that it could be just the harness.
Yes, the 4 cyl in the Disco (I assume it’s the same as the F-Pace base) is dreadfully slow.
