Prius (2010-12) :: Gen 3 - ICE Keeps Turning Itself On And Wasting Gas
Nov 21, 2010
I have a warm engine (>150 f), the heat turned off, battery at max full, and a 10 mile coast downhill at 30 mph max, but the stupid ICE keeps turning itself on (SG says 5 - 10 hp doing nothing) and wasting gas. The only way I can find to shut the stupid thing off is to come to a full stop, wait a few seconds, the ICE shuts down, then I can coast a while more till it comes back on , repeat etc. That is ridiculous. Maybe a switch that tells the engine the car is stopped? Maybe an ICE override. Must be a way to defeat this. It can't be doing anything useful.

A few months ago I bought a used 2007 Mercedes C280. Overall, I've been very happy with the car. The first month or so was heavy on longer highway driving, and it seemed to be getting decent gas mileage. The last couple of months have been mostly short range city driving, and the mileage seems significantly less. I wonder about the idle speed, on the assumption that it may be wasting a lot of gas sitting at stop lights and in traffic. The tachometer reading isn't always consistent at idle, but fairly often it's up close to 9,000 rpm. What should I be seeing, and does this need attention?

When driving, I notice when the ICE kicks on. I assume this is normal but just want to hear from others.

Last November I had a left front end collision with another car. The other driver was at fault and their insurance covered everything. The car was in the shop almost 2 months.
Now it seems back to normal except the climate control randomly shuts off every so often. I usually leave it on Auto. After the car has been off overnight or sometimes just a few hours, I notice the climate control is off. After turning it back on, the temperature setting has been reset to 75. It happens about once a week. Doesn't seem to be related to outside temperatures.
Should I take it to the dealer for a check or back to the body shop? The body shop offers a lifetime warranty, but I doubt they could diagnose something intermittent like this.

I replaced the 12V battery yesterday with a new one, and the car (2010 Prius Model III w Navigation), will turn on and off, but the ICE is not turning on automatically upon start-up, as it usually does. I can get the ICE to start by stepping on the gas pedal while in park, although it seems to die within a few seconds if I remove my foot.

My 2011 Prius has delayed headlight turn off, which is nice once in a very great while. I have looked through the manuals but have not found any method to remove the delay so headlights just go on and off with ignition, like my 2006 used to do. There is nothing on the headlight/turn signal arm to adjust, so assume delay is "hard wired" into the Prius software. Of course I can turn headlight switch on off every time, but wondered if there is a delay kill.

There must be a way to "turn her off" but I have not found it in the book. When I want to "cancel" the directions being given, what's the secret?

When the front defroster is on, a little orange LED is lit on the defroster button.
When I press the Off button for the AC system, the orange LED stays lit on the front defroster button.
Is this normal?

When slowing to a stop and turning to the right, there is a ticking sound (not loud) coming from the front. The ticking rate slows as the wheel slows and continues until almost stopped. Break pedal pressure does not affect the sound. The dealer tech heard the sound on a demo drive but they had no clue what it was and found nothing wrong.
The tech, sitting in the right seat thought the sound was coming from the left side. I hear it coming from the right side. Maybe that means it comes from the middle? I only hear it when coming to a stop. Maybe road noise covers it up at higher speed but I don't know.
Currently at about 38,000 miles.

The past week I drove the 1800miles. This afternoon I went out, pushed power button, get out and clean windshield off and ICE turns on with this clunk clunk noise, shook the car like a sob too. Checked oil and it showed a clear metallic gray/Black tint with end the light tan oil.

I just noticed if I turn off the car without putting it in park it would do it automatically. Is that safe or do you always put it in park first?

Last night the TPMS light came on on my month old 2010 Prius. I checked all the tire pressures and they we @ 38 rear and 40 front.
TPMS light went off after 4-5 times of turning the car on/off.
What might have been the problem? Is it something I need to be concerned about?

2010, 72,000 miles, regular dealer maintenance. After a stop, turning left, a "stuttering" can be felt like under the drivers seat location. Not all the time. No sound or other abnormalities. At first thought it to be a section of rough road surface, as I first noticed it at one particular corner.

It distracts me too much and I can't seem to get better than 45 mpg no matter how I drive (regular mode mostly highway). Any way to turn it off permanently?

I've got a problem that has the dealer stumped. 2010 Prius TWO with 67,000 miles. While gently braking in the final stages (<10mph) and turning, a ticking can be heard from the left front brake. It is a very fast ticking, and is proportional to speed. The frequency of the ticking is very fast, think of holding a pin into the cooling fins of the brake rotor.
I had it at the dealer last week. They had it for 2 days, with the service advisor, manager, and director all driving it and listening. They ended up replacing the wheel bearing. No luck unfortunately. They've had the entire brake assembly on the floor and reassembled, no change. Tightened all suspense links, no change.
The circumstances are:
- mild braking
-anything more than just a slight turn (maybe only to the right?)
-slower speeds (<10mph)

How to go about turning off the signal flash when unlocking the vehicle? I grab the door and the signal flashes twice indicating unlocked, I do not like announcing to my neighbours every time I unlocked my car. My dealership tells me they do not know how? I was hoping there is a series of buttons to press or something like that. I have a 2012 base model (one).

It's kind of weird, when I turn into a corner that is packed with snow - my traction control light kicks on like it does, but it feels like the brakes are being applied.

I have noticed that if I push gas pedal while turning the corner, especially if starting to go uphill, there is significant vibration felt in the gas pedal. It happens every time, as I use the same road each day, for 6 months now. I recently had a rental prius for a weeks, and had the same experience, although not as pronounced as my car.

My car is having a problem of passenger side light (low beam) being always on even after turning the switch or engine off. I have to unplug it to prevent it from draining the battery.
I am not too familiar with electrical system on the Prius, but suspect bad relay or something related. Where the relay for the headlight is?
