Prius (2010-12) :: Electric Motor Only Used When In Reverse?
Apr 18, 2012
Does the gen 3 prius use electric motor only when in reverse? Reason I'm asking is that, I was in reverse and didn't see a rock that prevented me to move and keep pressing on the gas pedal and got no response and throttle response was zero even on the HSI screen. Had to move forward and back to reverse to gain momentum to go over the rock. Just a weird feeling knowing that the gas motor didn't even kick in even when pressing on the gas pedal.

Just walked by the back end of my new Prius III and heard what sounded like a electric motor running from the general area of the exhaust pipe at the right rear end of the car. This was about 5 hours after I last drove it.

Yesterday, at 8000 ft in the Arizona mtns, my 2010 Prius exhibited some strange behaviors. For several minutes the gas pedal was non responsive in the first half of it's travel, then it would lurch ahead in a jerky manner unlike it's normal behavior.
It seemed like the electric motor was not being engaged. It also seemed stuck in ECO mode. Pushing the economy mode button would not disengage economy mode. If I stepped hard on the pedal it would go, but not very well. After heading down the mountain to a lower elevation seemed to work.

After the car is parked for a while, when you open the driver side door or just touch the door handle an electric motor starts running. After several seconds it stops. Sounds as though it is running a pump and building pressure or vacuum. Just wondering exactly what it is?

I ventured into the garage late last night and heard a whirring noise like an electric motor coming from my Prius. I didn't have my smart key with me. I checked the doors to see if any were ajar. The whirring kept going. After a few minutes, it stopped.

We've owned our 07 since purchased new in 06. It's always made this noise, but it used to be for a short period of time (1-2 min). Now it goes on and on for 5-10 min. It sounds like it's getting "stuck" and starting the cycle over.

I went out to my garage a minute ago and heard my C making a weird noise. Like a small electric motor running. I finally pinpointed the sound to the bottom of the car back towards the fuel tank. At this point I thought my fuel pump was powered up because it sure did sound a little like that. I was saying to myself at that point that I am sure glad the car is still under warranty. So I went to get the SKS fob to start it up, hoping the sound would just go away. While sitting in the car prior to starting it, it occurred to me that maybe I should remove the fuel cap first. While opening it a slight "whoosh" occurred blowing fumes in my face when removing the cap and the farting promptly went away. The tank is down to two segments level wise, it is cooling down this time of the day, but I did get back from a long drive a few hours ago, so I can't see how the fuel or vapors were expanding enough to release through a pressure valve. So if you car is farting, remove the gas cap first before panicking.

So recently I was driving through highway 17 with 4 people and we'll my 07 Prius was slowing down like never I eventually smelled a little burn but I ignored it I just though the engine was working a bit to hard. Recently I noticed that on the energy screen it only shows that the battery is getting charged it sometimes used the battery to the motor but not often. I did notice though that I run with electricity more when I'm in the city. It's quite weird it's like the electric motor doesn't work on the freeway.

06' prius that I believe to be abnormal behavior. Just took the car on a 360 mile round trip. After about an hour of driving (Interstate 78mph) I happened to notice on the Energy screen that the car started to use the electric motor steadily for about 5 minutes of driving on flat terrain (Kansas). I watched as the SOC went from 5-6 bars down to 1-2 (purple). At which time the car started experiencing bouts of high rpm on level terrain/small hills. It stayed in this state for over 20 minutes or so of driving. It acted like it knew it needed to charge the hybrid battery, however the level never increased until such time as I exited the interstate and started braking. I am assuming that the HV battery should rarely discharge that much traveling at highway speeds on flat terrain.

A quick question, currently an observation.. but a concern. we purchased our 2012v used at 55k miles.. She's running great, MPG's are above rated expectations. (ave 47.2 so far) We are currently @ ~59400 miles.. So, all seems OK w/the exception of this strange noise.. I'm familiar with the typical prox pulse sound at low EV speeds.. and this noise is not that one.

My 2013 Prius v V with 60,000 miles just intermittently started to show 3-4 dash lights when driving: Slip, Brake, and ABS. Whenever this happens, I noticed the regenerative braking doesn't work and the traction motor refuses to turn off at a stop (like at a red light). The traction motor will turn off if I put the car in neutral. At first it happened with just those three lights, but now a fourth comes on...the LED lights indicator.
So what gives? Sometimes these symptoms last for days, and then they stop. Sometimes they stop for days, and then return. Once in a while they disappear (sometimes after a rest of a few hours) and then come back on after a short drive. Once, they persisted for days, then disappeared. A few hours later, however, I had the car parked with the power on for about an hour while talking to someone via Bluetooth (traction battery at 3/4). All of a sudden all the power to the vehicle cut off. When I turned the car back on a half hour later the symptoms came back and persisted for days.
This on again off again dance has been going on in a temperate Southern California Coastal climate (Orange County CA) and also in a hot desert climate (Coachella). It seems like a short...or maybe a problem with a brake actuator or sensor (same thing? dunno). I've researched this on the web, and couldn't find anything that matches exactly my symptoms. It seems to be related solely to the braking system, but why the LED light now? The LED doesn't come and go on it's own, it comes on in tandem with the other wheel-related lights. Very strange.

Have just purchased a 02 prius with a transmission that slips. Would this be a electric motor problem or actual tranny problem?

For the last few weeks, it has seemed that the battery gauge on my 2002 has been half full more often than it should. I admit that I have no good science for this determination, but about half the time when I return home from work the gauge shows half full, and it returns to full after about 1 - 2 miles of driving. The car has about 122K miles on it.
Today I took a long drive through some pretty steep terrain toward the New River Gorge in WVA. Round trip it was about 750 miles. On the way home, I got an error on the console. I'm not sure what it was, but on the main display there were three boxes with writing. I didn't read them as I was pulling off to the shoulder. By the time I got there, the warning was gone. I turned the car off and restarted it. Everything looked good and I headed the remaining 10 miles home.
Once home, when I turned the car off, I heard a vibrating noise from (I think) the left side of the hood for about 5 - 10 seconds. I turned the car on again, and there is a vibrating sound, and the same turnoff problem.
Is this the final death knell of my traction battery? I have a 120K servicing due about now. I have been planning a reinvolt battery, but it is a bit of a drive away. Should I consider trailering the car down?

Sometimes when my car as sitting at an idle in either drive or reverse the motor starts to make a knocking noise from the back of the motor towards the firewall side on the top of the motor. I have a video. The car has 114k I just changed the oil I thought maybe it's low but it's not and hasn't moved since it was changed.

Got our 2012 package 5 lesss than a month ago, so we haven't had much opportunity to use the rear defroster. The two times I have used it I noticed that it works well on the upper rear window, but the glass below the rear spoiler doesn't seem to be clearing. The red/orange "wires" are visible in the glass, but don't appear to do anything. Wasn't planning to head back to the dealer until first service since we haven't had any other problems, but this could be annoying with the winter weather.

My car has around 160k miles on it and for the past 30k miles (give or take) I have had a jerking sensation when the car switches from gas to electric. It is a stronger jerk at low speeds and more like a shimmy at 40-50 mph. It has progressively gotten worse with time, I mean it's by all means drivable but I have been trying to figure out what could be wrong before it has to be replaced and I'm on the side of the road.

It's an odd small electric motor sound. It happens when I get into the car and tonight I heard it when I turned off the car (had radio off) which that one was longer and had different pitches. It sounds like the power seat is adjusting but it's not. It's driving me nuts that I don't know what it is!
