I can do the calculation, but this map isn't for St. George, Utah (elevation 2,800 feet). It is for Cedar City, Utah (elevation 5700 feet, about 50 miles from St. George). Based on the elevation alone, I can say that Cedar City is probably going to be pretty good for the Leaf. St. George, not so much. Do you still want me to do the calculation for Cedar City?

Edit: The highs are 10-15 degrees higher in St. George than Cedar City.

Here is monthly average for Cedar City:

Thank you for doing this. It would be for a desert climate in St. George or in Ivins, UT. I would expect both to be less than ideal for the LEAF.

Looking at temperature profiles, I would say St. George is about mid-way between Dallas and Las Vegas, meaning an unscaled aging factor of about 1.41. It isn't going to be pretty, I would suggest lease only, and a short one at that.

Yes, that's what I suspected. Mark Larsen's LEAF will be facing the second summer there this year, and I suspect that he might start seeing some of the problems we have heard about from Texas and Arizona. The only saving grace is the low monthly mileage. I think adric22 still has all twelve bars, and it's because of a very short commute and low total mileage.

my leaf was sitting in the dealer showroom for 6 months and i did not know about the 12 bar's
i am sure that i did not have them as when i charged the car only showed 102 or 103 Miles and
it used to get about the 72 or so mile after driving 10 or 15 mile at 48 MPH when new then it is gitting worse . I think the battery show get a good check as it was checked and the report show 5 Stars and now i only get 55 miles after a full charge , it starts out at 88 miles and drops after 3 miles to 70 MPH
and keep's going Down going at the speed of 48 MPH. What has to happen to get the weak or bad cell or cell's replaced. If I have to wait till the bar's get to 9 to have them fixed what will the miles that i can go?? :|
My car was sitting in the Showroom for 6 months as it was a demo for people to see before ordering the car as they did not have a supply. I live in Arizona and when it was 110 it got better mileage with the air on ,Does the heater takes more?

you need to update your profile and add a location. it is critical in these kinds of battery situations.

at least update your profile or explain to me how your car was sitting in a showroom 2 months before the first American delivery
Ron, I sent you a personal message. Check the top left corner of this screen, just underneath the MyNissanLeaf logo (green profile of a Leaf) and you will see "Logout" on the left and just to the right of that "X New Messages." It should say at least 1 new message (from me). ;) Click on that and you will see my PM.

The Temps are only a problem June, July and August. A swamp cooler in the garage could lower temps 15 to 20 degrees and the cost would be small compared to buying a new car every 2 years.

That sounds like a solution, provided you can leave your car in the garage for 3 months straight. :o For those who have to work for a living, it might be a problem.

Hey I have to work for a living, same as you. :)
My car does spend nights in the garage, same as you, same as Mark. During the day at work I make an effort to park in the shade. I just think the swamp cooler can keep the car cool at night when it is charging and that may help over the long run.

that might be doable as long as you are no higher than 70-80% SOC (purely a guess here) that will help to reduce the degradation although not sure how much since plenty of AZ'ens only charge to 80% and still had a lot. but pretty clear that ca full charge in heat is not good.

Don't add the GOM or use the GOM to determine range. It won't help us at ALL to determine if there is a problem. Thanks.

How many miles did you drive (physically drive) and how many fuel bars were left?
