Good luck Kermit
I think you have had too many issues already with your car sadly
I would definitely be phoning and pushing every day,
When I had my similar problems last year that seemed to be the only way to get things moving !
If it is of any re-assurance to you my car has travelled more than 9700 trouble free miles since being sorted, fingers crossed for you
Thanks Malcom. I'm monitoring closely the 12V battery voltage by Wattcat and it never goes too low with one exception after one HV charge some days ago. I'm now prone to think that in this case the warining is not related with the auxiliary battery voltage but rather with some sensor feedback. In any case one week from now and that car will be collected by JLR, so I hope I will make it till then.

I have had indeed some problems, or at least a big one, but some how I was expecting this as the I pace is the first EV from Jaguar and it has been built in a relative small numbers. In other words I knew I was going to be a sort of beta tester. But it's by far the best riding experinece I had with a car, so it's ok ;)

Update: Got my car back after 10 days at the dealer. They removed the battery control module and refitted it as advised by Jaguar Technical Department. That solved the problem but they still do not know what caused the fault.

I am just glad to get my car back. I hope the issue does not occur again.

I’ve had this issue to. Brakes stoped working at 60 km/h but luckily the road was clear and after that we had to get towed for the second time in 9 months. Spent 3 months at the mechanic in total in our first 9 months...

I got the reduced brake pedal feel message last Tuesday. Thursday afternoon I got all the other messages - ASPC not available, emergency brake assist not available etc. Brake pedal wouldn’t operate. Car recovered to dealership. Software updated and problem sorted. Auxiliary batteries weren’t being charged.

My i-pace has been in and out of the workshop due to misconfiguration of software updates, inability to charge, failed power control unit and a low speed collision due to loss of brakes. Back in this week for a failed steering column switchblock (no controls, no Intelligent Electronic Braking).

15 weeks in total in the workshop over the past 16 months.

Jaguar HQ is directly involved trying to resolve but is sub-par due to furloughing Jaguar Onward Mobility and closing my local repair centre.

Car does not feel safe to drive, has caused one accident so far and obviously has serious faults.

I am probably going to claim breach and return the car to Jaguar. Which is a shame because it’s a great car when it works.

Buyer beware, we are guinea pigs.

Sadly I’m too aware. Most of my problems boils down to the 12v system which for me is a bit of a let down, since cars have been running on 12v like forever!

Today same story: picked up the car and got the error message. Droved few km, switched off, then on and the error was gone. Droved more km, parked the car for 2 hours and when I switched the car back on I got the error message. Wattcat is reporting 14V during driving and 12.9V about 3 hours after I parked the car. I guess tomorrow I'll have to call the dealer...
I had suffered from the same problem a month ago. I suspected 12V batteries and let the service technicians checked the 12V batteries, but they said that my 12V batteries had no problem, so they did a swap some modules with a testing I-Pace. Finally, they found the Power Supply box was stuck and changed it. So far, there is no problem at all.
If your 12v batteries have no problem, the Power Supply box should be checked.

Sorry for my poor English.

I feel very confident that WattCat over-reports the voltage.
I have a Bluetooth voltage measuring box connected to my battery directly. WattCat report 0,9V too much in my car.
That means if WattCat report 12.8V then your car battery is actually 11,9V.

Thanks for the tip but I had my car serviced last year. I don't know what JLR did, but after that the problem did not appeared again so I guess they fixed.
