Well, this is new....

When I put the car into Eco mode, the range drops like 35-40 miles. I go back to normal mode and it comes back up.

My eco panel still doesn't work - it shows the AC is on but doesn't show any change if I turn it off.

Loving the new software...

 

[Meldev##44]

Sounds bass acwards to me.:surprise:

What new software do you have?

Was it OTA update?

 

[sciencegeek]

Yeah that's Blulsiht. Yet another bug.

 

[sgtpeper]

I've tried the OTA update a bunch but my car claims to be up to date. All of this is from when I had the dealer do the update from the recall..

 

[sgtpeper]

When the car is fully charged in normal mode it says I have 272 miles. When I switch to Eco mode it says 201 miles....

Basically, I have no idea how much range I ever have left. I was driving the other day and it showed 50-60 miles left. I put it in Eco mode and it dropped to 14 miles. I put it back in normal mode and it went to 40 miles. Then dropped.

By the time I got home, it said I had 10 miles left - no warning came on or anything.

 

[sgtpeper]

See picture below. With the A/C on apparently I'm losing 136 miles of range??? If I turn it off it drops to 135 miles... Makes no sense!

 

[bruintoo]

Have you tried resetting the GOM? (Turning it on without pressing the brakes, and pressing both brake and accelerator pedals simulataneously for about 10 seconds)

 

[sgtpeper]

That no longer works on my car.

 

[Sbingham60]

That no longer works on my car.

Not experiencing the problem you see, but I didn't get H228 applied and I'm still on S18D for Infotainment. Pretty sure I'm still on 14.2 Telematics, but have no way to check.

I have owned my First Edition I-Pace since March. It ran great for the first couple of months until the dealer did the two major JLR mandated updates. Since then I have experienced range issues. Initially, I was told that the H228 Software Enhancement Program would fix these issues. So back to the dealer and H228 was done. This did not fix the issues. It appears that the two major software updates have destroyed the vehicles ability to adjust range based on driving style, terrain driven and traffic conditions. Since H228 my dealer had a visit from Martin Barratt who is the national EV specialist for JLR NA and he worked on my car. I have, since then, communicated with Martin several times and I will give you some of the salient points I have discovered from him.

Previously described range reset methods no longer work. Current JLR recommended method is to gun the vehicle from standstill to 45mph 3-4 times. This needs to be done in Eco mode. The fully charged range will then reset to 282miles. If you switch to Comfort mode the range will revert to 201miles. These two fully charged range predictions are the only ones I can get on my car currently no matter how I drive. Unfortunately neither of these numbers are close to being real. I have calculated that my actual range averaged over a combination of city and highway driving is around 180miles. My average range prior to the major software updates was around 210 to 215miles. Martin Barratt stated last week that JLR Software Engineering is working on a fix for these issues. No release date is yet available.

272 miles is hypermiling. It's possible if you are good, but it's not that fun to drive for 5 hours for a range test, trust me.

No matter what the GoM has said, I know from experience what to expect. I get about 50 miles per 1/4 tank driven at 80 mph in hilly terrain with AC on using the Eco setting and ACC.

Sidebar - Coming back from Vegas at 85 mph Sunday, I knew my car would make it. But when I was 60 miles from home, the GoM said I would not so I slowed to 75mph. At 40 miles, it said I'd come up 20 miles short, but I know my car. I stuck with the 75 mph though, maybe the car knew something I didn't. Slowly the negative numbers rolled into positive numbers. When I pulled in the driveway, I had 13% SOC left. So I could have stayed at 85 like I thought.

Your Range Warning can be set at 10%/20%/30% but I don't know if you can turn it off. I leave it at 10% which will get me about 30 miles in a pinch. The last 10% is more than 10%.

 

[dtgsrq]

I can confirm the bizarre (and totally embarrassing to JLR) behavior of the GoM: Range at 100% SOC reads 282 mi for all modes but Eco, which exhibits 201 mi. I can also confirm that the 3 'jackrabbit starts to 0-45 in Eco Mode" did reset my GoM, which had been reading 201 mi at all modes for 100% SOC. I took this video about 10 mi into my drive today...

[sgtpeper]

3 hard starts hardly seems like a safe way to reset the system, no?

Mine makes no sense at all.
@McRat - its great you know your car so well. Mine, on the other hand, doesn't seem to work that way. I don't even get a warning when I drop below 10% - or 5% for that matter. My range also seems to be diminishing with each charge. In summer weather I was getting about 220-230, now I'm lucky to get 190 - at least from what I'm calculating more or less.

I'm getting really sick of this car really quickly. Never have I had a car that drove so well but everything else was junk...

Until you posted "GoM DROPS when using Eco Mode" I was also having an unsettled feeling about diminishing range, although having just taken delivery of my 2020 less than 4 weeks ago I didn't know what to think (different car, upgraded software, etc.). Like McRat, by now (7 months) I feel like I know the I-Pace well enough to "override" the unreliable GoM, although in my case the experience spans 3 different vehicles (2 FEs, one a 5 week loaner), presumably all built to identical specs even with the 3rd being a 2020 HSE. I do have a sense that in the hot summer months (temps consistently in the mid-90s here in SW Florida) the use of AC and battery self-cooling detract slightly from range. I haven't measured power use, however, and now with the GoM a bit crazy I can't confirm that suspicion.
Glad you posted about this, however, as now that I've fully recreated the issue it is most definitely a (solvable) software issue. I must say JLR's software QC is pitiful... how did no one notice this gargantuan (81 mi) swing in range (and even OPPOSITE of expected, with Eco being lowest???). Sgtpeper, I haven't bothered to report this issue, so you can feel free to include the video link above if they dispute your complaint.

 

[sgtpeper]

Thanks. It's very frustrating and making range anxiety pretty bad.

When the car gets down low, the range seems to change quite a bit - or sometimes it doesn't change at all.

I swear, if Jaguar had put some real money into the software on this car it could be one of the best vehicles on the road today. Instead, I don't feel like I can trust it from day to day.

 

[sciencegeek]

Ok I totally agree that the software is buggy and that it's ridiculous that they still ship new versions that fix one thing and break another. That said, I don't understand why the GoM bugs induce any sort of range anxiety.

Ignore the GoM. Look at your SoC and make it a policy to charge to 80 or 90% when it's below 30%. It's just like a gas gauge in an ICE vehicle. You look at the gauge and decide to fill up when it drops below your comfort level.

How do you set the range warning?

 

[sgtpeper]

The difference is the inherent nature of an EV - I can fill up just about anywhere in an ICE vehicle. If I can't rely in some way on how much power I have left, then I'm left anxious.

I live in Colorado and we have a lot of elevation changes. So sometimes a 1/4 tank can take me 75 miles it seems, and sometimes I get 30. I never really know what I'll get.

 

[McRat]

How do you set the range warning?

Let me go look. BRB.

 

[McRat]

OK -
Navigation title bar
Settings (gear icon on bottom border)
All Settings?
Electric car settings
Check the Auto-add Charge Stations box
Right below that will be a selection about Range Warning
Click it and it will show 10/20/30 settings.

I think you can turn if off by NOT checking the Auto-add charging stations box.
