2010 Prius - Next Generation



  • canccanc Posts: 715
    I agree with others when they said that the Prius keeps the coolant warm for long periods of time, which reduces the need of having a remote starter. That being said, it sounds like your mind is made up when it comes to having a remote starter--I'm sure it's possible to hook it up to the ICE, but bear in mind that the car might run for the first 30 secs and then switch to the electric motor, foregoing any advantage to starting up the car in advance. Just my 2 cents.

    Dear Sas9,

    Don't worry about water getting into the batteries--both the 12V and the battery pack are in the trunk! The Prius was meant to be driven like a traditional car, so take care of it the same way you took care of your previous cars.

    We have this accessory installed in my wife's 2010 Prius IV w/solar. It was mainly for old Winter morning warmups. The engine stays on for 10 min before it turns off, and can be restarted for one more 10-min duration. Everything automatically shuts off once you touch the door's handle to prevent any possibility of thief. It allows the seats and vent to be warmed before you get into the car. This will also allow for longer AC function in the summer time (longer than the regular AC function from the solar roof ~3 min). You do need to pay labor in addition to the cost of the parts just like anything after-market or out-of-lot additions to any cars.

    Those quirks are gone.

    It's quite impressive the refinements the 2010 offers.

    I just picked up my 2010 Prius IV. When I first start the car, the engine comes on. I thought that only the electric motor should run when first starting out? Any thoughts would be appreciated.
  • This sounds like the 'ol Winter Blues of Hybrids. Summers mean no "heat" necessary (near 50 mpg's)....BUT....Come Winter things require engine heat for your warm interior (milage drops to low 40's). Simply put...on cold days ya gotta have engine running in order to get the heater out put. Also, there's the issue of more demands on electrical (heated mirrors, Rr defogger, etc) and as everybody knows... batteries lose some degree of energy in cold & sub zero conditions. I hope this helps you appreciate what you're dealing with.
  • The Prius is a gasoline car that gets great mileage because it has a very small ICE engine. It gives unusually good performance for a small ICE because it has a battery driven electric booster for acceleration, passing and (fairly short) uphill needs. It is not a plug in hybrid which is a fiction, except for former CIA director James Woolsey, who's Prius was modified, at great expense, to go 40 miles on the batteries which take up the entire trunk and weigh a ton. The only time your ICE will always be off is backing out of your garage, because reverse is electric only, and when in your garage turned off. Normal driving is done by the ICE with the power transmitted directly to the drive shaft saving the loss of generating electricity for the battery and a similar loss of getting that electricity to the wheels. Most auto reviewers don't get that because the combination is so seamless that you can't tell by driving the Prius.

    >> very small ICE engine

    The 1.8 liter engine is hardly anything considered small. In fact, that is the same size the base Corolla uses. Small is 1.0 liter, which is what Smart uses.

    The engine can remain motionless up to 46 MPH. So, it is very common to be driving along city streets using nothing but electricity.
  • That is just not correct. Even the EV option, which I installed but now never use, is programmed to turn the ICE on at 32mph or when accelerating. My 2004 works great, gives 45mpg consistently with the engine almost always on unless I'm at a stop light, going down a pretty steep hill, coasting to a stop or in reverse. That is based upon observing the display as it is almost impossible to hear the ICE start or stop except at a stop light or in reverse. John may have made another modification to his Prius which I would like to hear about. I use to read his very informative website when I first bought my 2004.

    John has a 2010 Prius (which btw is the subject of this discussion). That may account for the difference between your 2004 and his car (and other 2010 Priuses).
  • john1701ajohn1701a Posts: 1,897
    >> That is just not correct.

    My aftermarket gauge clearly drops to: 0 RPM

    Countless other owners of all 3 generations have confirmed the 42/46 MPH threshold for driving with the engine stopped.

    Electric-Only propulsion like that has always been a standard behavior for Prius, hence the 9-year old terms of STEALTH and FULL to indicate how the design differs from some other hybrids.
  • I just got mine installed. I have the same car as your wife and my experience was the same. The 10 minute thing isn't quite enough to do the trick on frosty days but is fine, and I don't really understand the whole shut-off feature, but I do like that everything is integrated into my smart key. We did pay around $650 though, much more that your average car starter!!
  • i have a 2010 and it definitely jerks forward when i hit potholes!
  • What is the cubic foot capacity of the Prius 2010 with the back seats folded?
    Google search does not find this info, nor did the dealer.
  • I will do a test again tomorrow and let you know.
    My ICE will turn on way before I hit 40mph even starting with a fully charged traction battery. I will accelerate very slowly as to not set off the acceleration trigger. I can creep with the car in drive, no brake, no gas and get to 10mph.
  • john1701ajohn1701a Posts: 1,897
    >> My ICE will turn on way before...

    The emission system must be HOT before the engine will shut off while driving with only electricity.

    Odds are, that's the part you've overlooked. Speed makes no difference when the vehicle places such a high priority on emission reduction. Draw must be in the "green" zone on the Eco-Meter too. The "white" will trigger the engine to start back up, since that indicates electricity demand has exceeded the kW threshold.
  • I have a 2010 that does the same thing. I am ready for this surge most of the time and am prepared to brake if necessary. Am I right in suspecting that this racing of the drive wheel(s) as it restores contact with the road is the characteristic that leads to the shut-down on ice or gravel that I have read about? In other words, when the car senses free wheeling or next to no friction (because it is is airborne in a pothole situation), in order to prevent some kind of damaging runaway spinning, it shuts down. I have been on snow and ice a little bit so far and have not had this traction problem, though. I worry about it it happening, however. Generally, i like the car a lot.

    We are debating between Prius II or Prius III with navi and solar roof. Really only interested ni the roof, but is it worth 3800$? We live in central California where it gets over 100 regularly in the summer.Does the solar really make a difference in care temperature?
  • dmathews3dmathews3 Posts: 1,739
    If the inside is 120 degrees and it is 100 outside is it really going to matter if the solar drops the temp to 100 degrees? To me it wouldn't be worth $3800. Now if it was able to run the air conditioner and keep the car cool which I doubt the solar panel is strong enough to do then that would be a whole different ball game. Say be able to turn air on at set time and open roof to exhale the hot air then I'd pay $3800 but not now.
  • kdhspyderkdhspyder Posts: 7,160
    Yes you can do that as you walk up to the car before getting inside. There's an AC button on the key fob.
  • My new 2010 jerks forward after hitting larger potholes.
  • sas9sas9 Posts: 28
    Is there a trick to tune into a station? I want to listen to Howard Stern on 100 or 101...the scan button jumps past these station numbers. I live in LA so it shouldn't be a reception problem. Any ideas how to get this station? Thanks,
  • dmathews3dmathews3 Posts: 1,739
    Could depend on which service you paid for. You need to check with sat. provider as there are different price ranges and you get different programing with each. Sounds like you need a different package.
  • Apparently others have experienced similar problems and Toyota may have a recall on the break system!! Like you, I am usually prepared for the surge forward, but others have experiences accidents because of it! Just hoping it doesn't get worse or I don't get caught in a bad situation before Toyota addresses it!
  • carnaughtcarnaught 'zonaPosts: 2,330
    It sounds like they (Toyota) has addressed it as they're saying that the problem was corrected on those delivered since late Jan.

    After all of their lies you really believe them. Even if it is fixed as they say, most people in the back of their minds are always going to wonder, will it happen again and will I live to tell about it. To me I have enough to worry about these days without worrying if my car is going to take off like a bat out of he-- or worse yet, will it stop everytime I step on the brake. :lemon:

    And they knew about this last month, but are just now being forced to tell the truth.

    Gosh, what is next?

    Braking Info
  • carnaughtcarnaught 'zonaPosts: 2,330
    ...the auto companies aren't guilty of "fudging" (i.e., lying) on details that lead to their recalls.

    But, issues involving their cars means time, liability and the litigation that goes with it, and the resultant cost monetarily. Because of this, risking perpetuation of bad public relations, I believe they will take care of it and they have the resources to do it.

    If we were dealing with someone like Chrysler Corp., I'd be much more worried.
  • I've looked everywhere on Toyota's and Edmunds' websites for more information on the solar roof. Does it use the solar panel to power the auxiliary fan while the car is operating? Or is it only while the car is parked? Does the 3 minute maximum operation only apply to the keyfob activation or at all times? Does the solar panel divert power to help charge the main batteries when not needed to run the little fan?
    Thanks everyone for any help, sideman59.
