I am a having an issue with the a/c in my i-pace. It seems to work great for the first 5-15 minutes when driving the vehicle but then just shuts off. Next time I get in my car and drive the a/c works and then shuts off. Once it shuts off it does not start back up until i stop driving. It also doesnt start if i just momentarily stop, it seems to have to sit for a bit. Doesn't seem to matter on the charge of the battery or the drive mode which generally is comfort. I am not hitting any buttons, I am just driving when it goes from cold to warm. I have an appointment on the 10th, for this and a software update. Just hoping someone will say something like, 'just change the auto a/c shut off setting hidden in...."

I wish I could give you sage advice but you've done the right thing by scheduling an appointment. I can't think of anything you can do differently. When you say the AC shuts down is it just not blowing cold air or do the fans stop blowing?

I am no expert, but you need to become familiar with the various modes of operation.

Auto climate mode can revert to manual if you adjust (override) the fan speed or temperature dials. Some cars have up to 4 AC zone controls, perhaps there is some interaction if the temperature is set too high in manual mode.

Eco climate mode will cut off air for unoccupied passenger seats and reduce AC power consumption in other ways.

The AC symbol at the top corner of the display must be lit up (orange) to provide heat-pump heating or cooling. The air vents will still blow when the heat-pump is off. I believe that heated air is available from heating elements, but with the AC symbol lit the heat-pump takes much less power from the battery.

Cheers, Steve

I think I have a decent understanding of all these different modes. At first I was definitely in smart mode with the vents only blowing towards me as the driver. I turned smart and auto off, set temps to 65 tried a/c and max a/c but the above always seems to happen. I get around 45 degree air for about 10 minutes then it quickly rises to about outdoor temp. I can be driving along on a hot day, I wont touch any controls and the car is definitely not down to temp inside the car and 80 degree air will start coming through the vents. Nothing I do for the rest of my 50 minute commute will kick the a/c back on.

fan seems to work fine turns on and off when it is supposed to, responds to the speed control. it is just the temp of the air that seems to be an issue.

Hmm, I know that some folks have had their AC systems repaired or replaced. It's certainly an odd issue when the air blows alternately hot and cold. Hopefully the software update is all you need.

If your VIN ends in the range F75863-F76694, they were known to need the AC charge checked for having a low charge.
If not in that range, it is still possible to have a low charge or other system fault.

My vin is 64xxx. hopefully it is something minor like a charge.

I had the exact same problem...shut off after about 15 minutes. Mine is in the shop now. Supposedly it was low on freon. I should get the car back today, and it is really hot so I should know soon if their fix was correct.

Good luck an let me know if that fixes it. Mine is scheduled to go in on the 10th.

So far, so good on the repair. The car was low on freon. It's been very hot in Iowa this week, so I think the problem would have shown itself again if it were not fixed. They did not have an explanation of why it would be low on freon for such a new car.

I am encouraged that adding refrigerant fixed the issue but concerned they could tell you why it was needed. Hopefully they can do this work and the software updates for me in just 1 day.

I picked up my car today from the dealership and the a/c is fixed. The dealership evacuated the existing refrigerant, performed a pressure test which it passed, refilled the system and stated it is now operating as designed. I have a 50 minute drive home and i had a/c all the way home! I would have preferred that they found a problem that was then fixed but at least its working.

And...mine stopped working again after 2 weeks of being fine. Back to the shop next week.

So far it has been working and it has been about 2 weeks but I am concerned since nothing was really fixed. I drive the car every day and probably put on 900 miles since the service. I will let you know if something changes.
