@ gascant Have you considered, or have you already combined the suggestion into a survey?
I have seen a few that I hadn't thought about until reading them. A "Please rate these ideas
1-10" survey would help determine which improvements/complaints are most important.

That's a good idea. Linkim and I were talking over the weekend and thought we would just run a tally of what seemed to be the most popular. Although one reason why we want to meet in person with Nissan is so that THEY don't have to depend on surveys :lol:

For those who are suggesting steering as an improvement, could you provide a little more detail? This sounds like something that could evolve into a presentation. Or if you have a video, we could embed that into the PowerPoint file we plan to produce.

This is only my opinion of course, but:

All of the below are likely related to the power steering algorithm that is used in the Leaf.

1) The steering effort is far too low at speed which in turn makes the car twitchy and dramatically reduces any feedback through the wheel of the road.
2) There is very little on-center feel. By that I mean that it takes almost no effort to move the wheel off the center position and there is also little self centering force at speed (which brings the wheel back to center by itself. Again, this gives very poor steering feel and feedback, and increases susceptibility to movement of the vehicle in crosswinds. More caster might also help with this problem.
3) The steering is essentially numb. It gives very little feedback of what is actually happening with the vehicle and the road. Car and Driver summed it up very well: "The steering feels like it is remotely controlling a set of casters at the front end."

Likes:
1. Electric drivetrain - efficient, "greener" driving powered domestically
2. Smooth and fun to drive
3. Exterior dimensions, which make for ample ground clearance and generous driver/passenger headroom

Improvements:
1. More range (150 miles instead of 100)
2. All-wheel-drive (could be an option) for winter driving.
3. User-settable charge percentage. 80% is too high if starting out from a mountain.
2011 LEAF at 71K miles, pre-owned 2012 Tesla S 85 at 98K miles
LEAF battery: 9/12 bars and < 49 Ah (-28% vs. new)
Tesla battery: 250+ miles of range (-5% vs. new)

Odd. My ICE vehicles are a 1982 Toyota Starlet and a 1973 F250 "camper special" (can you say pig?).
The Starlet has manual rack & pinion; the F250 has power "twin I-beam". That must be why I find the
LEAF steering to be quite satisfactory I guess, I'm used to each vehicle being very different.

But then my dash and nav clocks stay in sync, so I may have a non-standard LEAF. :?

Likes:
1. 100% electric = never needs gas, less maintenance, no exhaust fumes, smooth and quiet
2. Right sized for an everyday driver, comfortable for the whole family, and packs a Costco haul
3. High tech

Could be improved:
1. Double the range to 150 freeway miles - would handle those weekend trips also
2. Match the plastic bumper color to the rest of the car
3. Add SOC meter and use average miles/kWh since last reset for the guess-o-meter

Modifications made on mine: Leather wrapped steering wheel

I now know exactly what you are saying because tonight I was in 20mph crosswinds only going 38mph and it took some effort to keep it inside my lane. Btw, those winds are worse than going up hills as I had them the whole 30 miles and could only muster 5.0m/kW h vs. 6.0 on the same trip w/o any winds.

Mine has stayed the same as my cell phone since it was first set. I really like the clock and its location! It's the first one I've EVER had that has kept perfect time. All the others were at least 5 minutes fast in a short time and very hard to read while driving.

They have already done that with a firmware update. If you want the improvement (everyone that has had it said it is accurate now), just take your LEAF to a LEAF dealer.

Have you tried the 'brightness' button to the right of the 'trip' button? I have mine set to one less than brightest and it works great! You may want it all the way.
