No similar experience with the I-Pace, but have had the issue with other cars.
I assume both fobs behave the same and you've replaced the batteries to rule out the fob.
There is usually an area in the car where you can put your fob so it bypasses the fob battery and the car antenna.
Does it work there?
We had to have the actual transponder in the car replaced in one of our cars a couple years ago. It was an intermittent problem, and it took 2 dealer visits to resolve.
