Prius (2004-09) :: Check Engine Light Turned On For A Few Hours Then Turned Off
I always take care of my car oil changes on time. And in the last week my check engine light turned on for a few hours then turned off. And today it turned on again. I kinda regret getting rid of my scan gauge now.

From day one my 2012 Prius 3 has had a shake that starts at 63mph and goes away at 69mph. Sometimes it's worse then others. I can feel it in the steering wheel and the floor broards. I took it back to the dealer and they said they felt it but couldn't find anything wrong. They actually put new wheels and tires on it! It seemed alright for while but I noticed it again the other day, I don't drive that speed that often. I'm either below or above it but the other day I got caught in traffic doing 65 and noticed it right away. I made a new appt this next week at the dealer again. It's not real bad just more annoying then anything. I searched on here but couldn't find anything.

I stuck my phone down by the electric motor and recorded this while the car was running:
My '06 has been making this odd noise coming from the front of the vehicle. It's coming from somewhere under the hood on the right side (the driver's side), and I think it's under or next to the electric motor.
It happens when warmed up, and only when the vehicle is turned on. It doesn't seem to be related to the ICE, because the noise happens regardless if the ICE is running or not. In fact it happens rarely, so when I heard it I jumped out and tried to locate it (and recorded it with my phone).
Prius (2004-09) :: Winding Down Kind Of Noise From In Front Of Driver After Car Turned Off
I am brand new to the forum. Just got a 2008 prius from a small father-son dealership and am getting used to the new sounds (or lack thereof) under the hood. I am getting a " winding down" kind of noise from in front of the driver after I turn the car off. it does not happen unless I have driven at least a short distance: i cant just run it in the driveway and then shut down and hear it. Is this normal, and what might it be?

After starting my Prius the engine was knocking and shaking. After running the engine for 30 - 45 seconds it operated normally. The car is always parked in our garage and the outside temperature was approx 32 degrees or a few colder. I have 30750 miles on the car.

My 2010 Prius engine shakes/vibrates when the engine is showing between 50-75 MPG on the gauge/meter on the dashboard. There is no vibration when coasting (100 MPG on the gauge/meter on dashboard) or when I am accelerating pretty modestly. Only when accelerating very softly. It started a month or so after I had my spark plugs replaced at 133K miles last June 2015. It has gotten progressively worse. It is especially noticeable once the engine is warm or the outside temperature is warm. During the winter months the vibration was there slightly, but not nearly as noticeable as it is becoming now that warmer weather is here.

So my VR6 shakes quite a bit on startup and when I turn it off. I figured it was the dogbone mount. I did the clutch trick, jacked up the front end and engaged the transmission. Of course the engine shook a lot, in a forward to back motion, signalling the dogbone was bad. Shifts into and out of 1st and 2nd were pretty rough and i could feel it in both the driver and passenger seats during idle.
Well I just installed the ECS dogbone and while I can't really feel it much in the seats anymore, it still shakes quite a bit once the transmission is engaged. Low end shifts really haven't gotten much better either.
So I am thinking its either one of the other mounts, or the polyurethane bushing needs to be worked in. I am leading toward the former.
Prius (Gen 2) :: Idle Shaking - Rough When Engine Stops
I have problem with my 2006 Prius , idle shaking and when the engine stops its really rough.
View 2 RepliesPrius (Gen 2) :: 2005 Car Started Shaking Like Sputtering / No Engine Lights
I Purchased a used 2005 . Everything was great all weekend long, but this morning, the car started shaking as I was driving it down the road. I drove my 55 mile commute, parked and took my son in to preschool. The shaking started when I left the school. As I was driving (around 45 mph, accelerating to 55 on flat road), the car had some definite shaking like a sputtering shake, but there was no sputtering noise.
No engine lights are on. Could this be a balancing issue rather than an engine issue? Or possibly a joint? Do these cars even have a flex joint?
Prius (2010-12) :: Stutter Or Shaking From Engine When Accelerating From A Stop
I've noticed that when accelerating from a stop and turning onto an adjacent street to the left or right, there seems to be stuttering or shaking coming from the engine. I'm usually in ECO and only 1/3 of the way into the "engine half" zone on the HSI. It's not consistent but has become a bit of an annoyance.
View 19 RepliesPrius (2010-12) :: Started Making A Horrific Metallic Scraping Sound As The Front Wheel Turned?
Was about three blocks from home when the front of the car started making a horrific metallic scraping sound as the front wheel turned. I mean LOUD. Did a quick look for something stuck in the wheels somewhere but nothing. It's not like a branch stuck in the wheel sound, but scraping a shovel on a steel beam kind of sound. Braking seems to change the makeup of the sound, but did not stop it. Parked it in the garage.
I pulled the left wheel off, looked and looked, and looked. Nothing. Fear and sadness setting in. Everything looked normal....except....a faint line on the rotor very near the inside edge. Got a mirror and looked some more, and there, wedged on the inside edge of the pad's metal part and the rotor, was a rock the size of a bb. At most. Got a small screwdriver and hammer and popped it out. Done. Sheesh.
Seriously it was so loud it was amazing. So store in file folder for future reference if needed.
The line can be felt barely with a fingernail and is half the width of a pencil lead, and goes under the innermost 1/8" of the pad. I'm thinking do I want the dealer to pull and turn it, or is it going to affect my braking at all. Pretty much gonna leave it be I think.
Prius (2004-09) :: 2005 - CEL Started Blinking And Engine Shaking / Knocking
Driving home the other day I noticed some vibrations up front. Reminded me of out of balance wheels. Then the check engine light started blinking. Then it was on steady, then blink, then steady... Took it easy the rest of the way home. Code reader said P0138 Oxygen sensor circuit high voltage bank 1 sensor 2, and P0304 Cylinder 4 misfire detected. At home is where I saw the engine shaking and extra noise from it (visions of piston rod slapping around in there). Removed plugs (original? tough to get out!), compression tested all 4 cylinders (130 to 140), new spark plugs (had they been in there for 196K miles?). Start engine and same, shake shake with some extra noises that weren't there before (car just sitting in driveway).
View 6 RepliesPrius (2010-12) :: Slightly Shaking Engine - Rattling Noise On Acceleration?
Slightly shaking engine and rattling noise on acceleration,it happens when the car is hot and especially when the battery level is very low ,I guess is when as more load . If I accelerate and keep it steady at 20mph I can feel a constant vibration but goes away once accelerating more....like if you're driving on a rippled surface ....that is only when engine is on , doesn't happen on electric only.
The noise it sound like a tapping coming from the engine when slowly accelerating from 0 that goes away as soon I give more gas ,is annoying wile in the traffic.? Can the sparks plugs be the problem?they been changed 120k ago.....,I cleaned the egv pipe but problem still there. Like I said is only when the engine is up to running temperature.
Prius (Gen 1) :: Check Engine Light Turned On - HV ECU Malfunction
This morning, I tried to start the 2003 Prius and got a 'check engine' light and nothing. The cabin lights were bright so the 12V looked OK. After three tries, I used the VOM and measured 12.55 V on the battery. But the traction battery level looked unusually low.
So I tried again and it started. Using the ScanGauge, no codes were displayed. So I turned the car off and on three times and cleared the "check engine" light. Then I connected the Auto Ingenuity and read out:
P1636 - HV ECU Malfunction on the HV ECU to ECM bus.
C1213 - HV ECU Communication Circuit Malfunction between HV ECU and Brake ECU
P3002 - HV ECU Communication Malfunction on the HV ECU to Battery ECU
So it looks like there was an HV ECU problem that 'cleared while testing.' Certainly it makes sense to inspect the HV ECU connectors and re-seat them and clean out any debris.
Prius (Gen 2) :: 2005 - Check Engine Light Turned On
My 2005 Prius has 105,000 miles. The check engine light came on for the first time ever. Dealer will diagnose tomorrow. If it's the main battery, should I sell it?
View 3 RepliesPrius (2004-09) :: Engine / Red Car And Triangle Lights Turned On
Bought my daughter a used 05 prius. So far had had to repair the MFD, ac blower, 12v battery.
The engine light, red car light, the triangle light turned on. We replaced the 12v battery since we didn't know if it had ever been replaced. Drive the car for about 5 minutes, then all the red lights reappeared followed by not being able to accelerate. Immediately drove back home. First looked up the acceleration problem and it says to check engine coolant levels.
Low and behold the reservoir was empty. Purchased some, added it and drove around the neighborhood. The acceleration problem gone! Engine lights gone! Just as I am getting home, the dash lights disappear and the engine light only is lit, and red car on MFD. I drove it to our mechanic for error codes. It drove perfectly. As i go to turn off car, it wont turn off. It took another 5 minutes of power button holding, brake release and parking holding. It finally turns off.
Prius (2004-09) :: Keeping Engine Lubricated When It Is Turned Off
Does the engine turn on and off frequently lead to a lower engine life? I have always heard that the biggest wear on an engine happens when it is turned on. If the oil is draining from the Prius engine each time stops it seems like there would be a lot of engine wear.
Does the Prius (2010) engine have some way of keeping the engine lubricated when it is turned off?
Prius (2010-12) :: Faint Engine Noise After Turned Off
I had my Prius for almost 4 years and I'm used to all the hybrid noises: brake pump after opening the door, emission control pump hours after driving, high pitched inverter noise in EV, etc. This is different. Very faint and I only noticed it because I opened the hood right after driving. The car was completely off, but there was some small electric motor activated somewhere inside the engine. Is this electric coolant pump?
View 4 RepliesPrius (2010-12) :: Check Engine Light Came On And Turned Off On Its Own
My check engine light went off last month and when I had it looked at my dealership they said it was due to the seal where the gas cap locks into I believe. Anyway, a week later my light went off again and now they are saying it is the charcoal cannister which I found out is very expensive. Here are my two questions. First of all, can I get this part replaced and installed at a non-dealership? My second question is since they reset my check engine light, it came back on a few days later for two days and then turned off completely. Should the light have turned off on its own? Should I be concerned that it is no longer on? It just makes me wonder if they diagnosed this issue correctly or not.
