Prius (2010-12) Fuel :: Car Takes Too Long To Warm Up From Cold Start
It seems like it takes an awfully long time for the good mileage to get going from a cold start - even when it's warm outside. The last 5 miles of my commute are great, but the first 10 miles not so much. How much effect does ambient air temperature have on this process.

The road my house is on is a steep hill. In the morning when I first start the car I have two choices. I can jump right on the hill and start climbing. Or I can drive down the hill and do a little quarter mile loop before I start climbing the steep hill. Which approach is best? Or is there a better way to handle this?
View 19 RepliesPrius (2010-12) :: HV Powering Car After Cold Start
This is something I have noticed the last 3 months. I have had the car 2 years. When I first start it and it is completely cold, it will only run like EV mode (HV battery powering the car) even though the gas engine is merrily running and it is not in EV. We live part way down a small hill, so now I often discharge the HV battery to a point low enough to trigger the recharge function which keeps the gas engine running forever. It does this morning or afternoon, if it has been sitting a few hours and is completely cooled off. It did it in Sept. at 65F and it does it now at 35F.

Why I'm suddenly having trouble starting my 2010 Prius when cold? I depress the brake and push the start button, but lately, sometimes the car doesn't start. It will start as if I didn't have my foot on the brake and the dash will light up. To get it to start fully I have to depress the brake and hold the start button down for 10-20 seconds. Then it starts.
View 9 RepliesPrius (2010-12) :: Remote Starter Won't Start - Too Cold?
My remote starter didn't want to start the car this morning. It's been working fine up until today when the temperature dropped to 5-F last night. I sat in the car and used the remote start to see what was going on, and it fired up the motor for a second or so, then it shut down again right away. My in-car test was the 3rd start attempt.. When I pushed the in-dash start button, the car started just fine..
Any insights as to why the remote starter doesn't seem to like the cold? The entire reason I purchased that option was to avoid going outside when it was that cold.. and if that's when it doesn't work....
Prius (2010-12) :: Low Rev Cold Start With Delaying Engine Shutdown
My Prius is having a problem during cold start. When I bought it, the cold start was very energetic with a high rev tone then gradually regulate to a normal pace and petrol engine shuts down. But about 4 months I noticed the tone of the cold start has changed, it starts with a weak and low engine rev and delays to turn off the engine. Today it took about 10 mins to power off the engine. Got 2 months I changed my 12V battery (Bosch now), thought that these symptoms was to notify that battery is failing. But the problem is persistent despite I put new battery..

We have had a few mornings (in garage) where it would seem to not really id say a knock but maybe a clicking sound and it would quit right away. This morning that did not happen so i shut the car off and checked oil it was low.
Got under the car and can not see any leaking no oil on ground. So i had a QT i put in and that seems to quiet it after a few seconds.
I called local TOY dealer and they said its common for 2010 to use some oil and not much they can do. I thought what is a little it was at the end of the dipstick.
They said they can only fill it up and then have me come back in 1400 miles and see how much is used.
Prius (2010-12) :: Rough Cold Start - Engine Sounded Like Working On 3 Cylinders
So I had 1st rough cold start today on 2010 Prius with 72K. Wasn't too cold low 40s. The fix was to shut it down and then turn on again.
Engine sounded like it was working on 3 cylinders. It is probably ignition or perhaps valve train issue.. with ignition being prime suspect. If it happens again I'll pull and check plugs.
Prius (2010-12) :: Heater Takes Time To Start Heating On Cold Mornings
I wonder why the AC takes time to start heating on cold mornings. Actually. It gives warm air after about 5_10 minutes of driving. Is that OK?

I've had my 2010 Prius for about 3.5 years now and this is the 3rd maybe 4th time happening. This morning I started the car and the car started to vibrate/rattle from the engine bay. It almost sounded like the wheel of fortune being spun but louder.

This morning I was playing around with my 2010 Prius "B" mode - I realize today that when the Prius CVT is in "B" mode the Prius ICE won't turn off even when it is at a complete stop -- instead the ICE runs/idles at a 996 RPM / .20-.40 GPH while stopped in traffic. The coolant temperature (@190F ) doesn't matter, Battery State of Charge (54% soc) doesn't matter. To re-enable the stop-start idle technology - I had to switch the Prius CVT back to "D" mode. I end up burning a bit more fuel on this trip because it took me a while to realize that I was in "B" mode and that the stop start idle technology had disabled in the "B" mode ...

Lately my transmission has delayed shifting into first when I shift my car into drive on cold starts. It delays for usually about 2-3 seconds then kicks hard into first. The rest of the shifts are smooth and on time. I've tried replacing my transmission fluid, but that doesn't seem to fix it. Is there an actual problem with my transmission? I had the TCM replaced when it would get stuck and not shift. I have a 2009 GLS with around 53k on it.
View 6 RepliesBmw - X3 :: Electric Radiator Fans Run On High After About 10 - 15 Minutes Of Cold Start Drive
After about 10-15 minutes, following a cold start, this 2007 BMW X3 3.0 six does the following:
1) automatic cabin fan behaves erratically, jumping back and forth between low and high speeds;
2) cabin air does not heat;
3) electric radiator fans run on high;
4) coolant temp rises to normal, but then will suddenly jump up to full hot.
At this point, driver of course pulls over and shuts off engine. The amazing part is this: the engine can be re-started IMMEDIATELY and all of the above problems vanish instantly. Radiator fans shut off, temp returns to normal, cabin fan works normally, and cabin heat comes on. I'm thinking sticking thermostat, but why does shutting off the car momentarily fix it? Change of water pressure when coolant pump stops running?
Prius V :: Best Way To Drive For Fuel Economy
I have a 2013 Prius V and my mpg averaged about 43. Now after about 13,000 miles it has gone down some to more like 41-42 and even 39. Once on a mostly highway trip it was down to about 34. Last summer it got 51 mpg in Colorado!
How to get better mileage. I once heard about a feathering technique with the accelerator but I don't know if I understand it.
Prius C Fuel :: Below Average Mileage During City Drive
I'm so fed up with this Prius C. I did nothing but city driving and I got 302 for a tank at 8.247. It's going to the dealership to see if something is wrong. I haven't got over 369 on a tank before and that was highway driving.

I am new to the prius 2010.
I filled up last week and I noticed that as soon as a single cell display in the fuel display part has some empty section like 3/4 fuel(single cell) the next day or after that that whole cell disappears without it showing that single cell as being empty.
Around which fuel cell, when displayed, is it important and recommended to fill up gas again, with one cell remaining or two etc.
Prius (2010-12) Fuel :: High Fuel Consumption While Coasting With Charge Available?
When I go out to do errands around town (I live right in town) I get horrendous gas mileage. Now, I understand gas mileage is high at the beginning of a trip, but for this long and this high and under these circumstances? I'm getting ABOVE 10l/100km when I have 80% charge available (for americans, that's disgustingly high MPG like, pick-up truck high), AND my foot is completely off the gas. Literally, coasting, or braking, and I'm still sucking up gas. What the heck?
Is this just because it takes a certain amount of time for the engine to run no matter what or something? I still don't see any reason for me to be eating up all that gas when my foot isn't even on the gas AND most importantly, I have charge available. Feels pointless for me to use my car for what I use it for 70% of the time, which is for quick errands around town at low speeds. Thought the prius was suppose to be a superstar for this kind of thing.
Prius (2010-12) Fuel :: One Bar Flashing Fuel Light
So my fuel light started blinking after 480 miles. How much more can I drive it? The display shows 30 miles left before fill up but I read in the manual that when the fuel light starts blinking there is 1.6 gallons left so should that be like 75 miles left. Just wondering. To be on the safe side, I went to fill up.
