Honda dishonest about EV Range (in cold climates)

  1. Also worth mentioning...

    I checked my tire pressures two days ago and they were consistently low, some near or even just under 30 psi. That surprised me - I checked them just after purchase in November and at least once since then. Colder temperatures may be part of it, but it’s not substantially colder than last I checked. Or, one of my gauges may be off from the other (checked at different locations with different dial gauges).

    In any case, no doubt that did not help my estimated EV and actual miles.

    We’ve been getting 31-35 EV miles in temps that have been in the 20s and 30s with some teens too. Using 33 as our winter average, that’s 14 miles under the 47 stated average. Unfortunately we’ve never gotten 61 EV miles in warm weather (the same deviation of 14, but over the stated average of 47). The highest I can ever recall was perhaps 57. The type of driving we do has been the same regardless of season. We don’t drive aggressively, but we also don’t drive like we’re in a race for the greatest range ever recorded. IOW we drive normally. :)

    A bit disappointing, but we still really like the car.
  3. HERETIC!!!

    I just had to add air to my tires too. The cold weather in Michigan deflated things quite a bit. All were evenly low, so no leaks.

    1 PSI for every 10 degrees Fahrenheit. I've over inflated my tires by 3 PSI to account for the higher temp in my garage. Averaging 41 mi range with temps in the low 20's nights to mid 30's days. Car interior temp set at 60 degrees and running in ECO mode but I turn off the seat heater and wear a fleece vest which feels very comfortable.

    Direct quote below from Clarity owners manual...and pretty much every owners manual for every car out there. I agree with this statement strongly and find it to be true year-round with the exception of spring -- sometimes as weather warms, I find myself letting a few pounds out of my tires for a couple months:

    "At least once a month or before long trips, use a gauge to measure the pressure in all tires. Even tires in good condition can lose 1–2 psi (10–20 kPa, 0.1–0.2 kgf/cm2) per month."

    Everyone should be manually checking their tires at least once a month. If you don't, they're probably not set where they're supposed to be.

    How much cabin heat were you using?

    It's good exercise to hit the bike pump for a half hour every now and then, too :p

  9. As little as possible. Though cold, it’s been sunny, so the greenhouse effect helps!

    Summer home in upstate NY and winter in FL.. Purchased Honda Clarity Plug-in Hybrid based on combined mileage. Bought end of June and most of 3,000 miles electric. What we told by the sales “pro” for this model was not completely accurate and it appears from taking car to two different dealerships the sales staff do not have a clue about its technology. I learn more from these forums. FL dealer point person told me this car is not a true hybrid and told me he needed a 10 rating, really? Anyway I digress. On the trip from NY to FL mid December I realized this car does not cold weather and would not encourage anyone in cold climate to purchase. After 45 miles car switched to gas. We travel with large dog and charging stations not available where we stay. First & Second nights temps dropped to 30’s and the following AM’s car started on residual electric switched to gas as I entered interstate and speed would not go over 45 until I had driven 2 miles on the pullover lane. It was like driving a car with a bad transmission. After that car ran fine both days. Lesson learned start trip on gas and hope overnight cold doesn’t deplete too much electric.
