201 Miles on the GOM how many want JLR to fix it?

Kind of ridiculous to provide a set 201 miles on the GOM after a full charge regardless of drive and environmental history don't you think?

JLR needs to provide accurate mileage and SOC yes? Any thoughts?

Hope they're listening and will take the time to do something about it...

Unless you have a bad battery, the SOC displayed is accurate.

Dantrium is correct, the SOC has always been accurate. The only issue is IF the battery has a failure then the SOC may be right, but the total capacity may be lower.

There is a reason we say GOM (guess o meter). It is a guess based on many factors, including outside conditions, history of driving conditions and it can never be perfect. In fact if I have been driving like Grandma and all of a sudden I start driving aggressively and climb hills it can be 30-40% off. Not that it should be stuck at 201, that seems to be some stuck algorithm factor and may age out as you drive more and more (the GOM probably uses short term and long term data to provide a guess).

So I wouldn’t worry about the range displayed. If you haven’t try the GOM reset procedure, or give it time. I always suggest reset your trip mileage when you have full charge, then just look at what you have driven and SOC to get a better idea of how much range you have left.

PCM (powertrain control module) software may not be up-to-date. Check your vehicle VIN with this bulletin.

Try resetting your GOM. Search for the topic somewhere here in the forums.

I have a phone based spreadsheet that does WAY better than the GOM with a simple strategy. In English, the idea is - if you continue to drive as you have since the last charge, this is the range you should expect based only on the %SOC of your battery.

I store the % of charge since the last time I unplugged the car, and reset the Trip mileage (or store the mileage).

Then, every 5-10 minutes on a trip, I plug in the current SOC and Trip miles driven.

Remaining Range = Miles Driven * Current SOC/ (Starting SOC - Current Soc)

That tells you "If you keep driving as you have been (in the conditions you're currently in) - you can expect this much range.

Total Range (Since last charge) = Miles Driven + Remaining Range

The GOM should calculate that way. I have asked WattCat's author to consider incorporating this simple Range screen into his app - since, he can automatically poll the car for the mileage and % SOC.

This method has worked on all my out of town trips, and been VERY accurate after driving only 10-15 minutes.

I just had the latest flash done according to the dealer.
For 2 days it read correctly, now it's back to 201 miles again.
I've had the 201 error most of my 16,000 miles, it doesn't affect me since 'gas gauges' are never exactly accurate.
But it was pretty sweet to hypermile it and have it show over 270 miles based on my gentle driving.
My experience is that when driven aggressively, I do get about 200 miles per charge.

mine also does the same, allways shows a range of 201 miles when fully charged, whatever the driving conditions and temperature.

also drops to 0 after driving 110 miles at 65 MPH average in eco mode and cruise control on on a highway, a very very long way form the advertised 240

What is the % of the battery shows when you're at 0 on the GOM?

So I happen to have a car in this range and Topix also does this this campaign outstanding for my car. What's the impact of not doing it in a timely manner? The bulletin basically says if it's in the field already chill & wait to hear from us - but that seems very counter to the presales perspective of "do everything in your ability to not deliver a car requiring this update".

I'm not experiencing any issues, but I'm just curious why it would seem fairly urgent on non-delivered and not so urgent on vehicles on the road. Thanks!
