Prius (2004-09) :: Strange Engine Noise - Power Supply Malfunction
Apr 18, 2012
I do a lot of diagnostic and keys programming but my mechanical knowledge isn't' that good. I had a minor accident last week and a car hit my Prius from the passenger front corner, Areand left a small dent, check the red X in the pic.
I noticed after the accident that the engine noise was much higher, I checked all ECUs with Techstream, I found only one error on the Transmission ECU:
C2318 Low Voltage Error(Power supply Malfunction).
Cleared it and didn't show again even after driving 200 milesIs
there anything behind this area that can cause that noise? or something responsible of reducing the engine noise might be damaged or broken?

I bought a 2007 Prius with 198,000 miles on it. Since then I've got it up to 200,000 ish. The previous owners took very good care of it, and did not encountered any severe issues.
I recently took it in to a toyota dealership for the free inspection, and they said it was in remarkably good shape. I asked about the engine noise, and they took it for a drive and said everything sounded pretty normal, at least compared to the prius with 130,000 miles on it that they had apparently just serviced before me. I went ahead and lifted up the hood, set my phone recording at the front of the car, and started it. I let it run for a few seconds, then shut it off.

I have a 2004 Prius. I purchased a used brake control power supply and installed it. Do I have to reflash it?
I tried to relearn the Linear valve offset. I've tried to INITIALIZATION OF LINEAR SOLENOID VALVE AND CALIBRATION with the factory scan tool. I have both. The older one seems to work better when working on Gen II Prius. I also tried to reset the YAW rate sensor.

I first noticed a strange noise coming from the engine compartment a day ago. I had left the car to sit in the sun for a few hours. When I got in the A/C was set to on and the system was on auto. I tested to see if the noise went away when I turned off the A/C and it did. I turned it back on and it returned. I know the A/C operates at different speeds based upon cooling needs and that it can get sort of noisy but I didn't think that it could/should get this loud. The system seems to begin working quickly and it does seem to put out cold air. If the noise is unusual do you think that it indicates another underlying problem in the A/C system?
Just to clarify, the ICE is not running in the video. The cabin fan is set to low and the temperature is set to low. The person in the car presses the A/C button and the cooling fans in the engine compartment come on as well as the A/C unit. The sound gets louder a few seconds in. Here is the link to the recording I made of the sound.

I have a 2005 Prius with 218,000 miles. Over the past month or two it's started making a horrible noise, which has finally gotten to the point that I can barely stand driving it. I used to keep my radio around 25 or so, but now need to crank it to twice that to hear anything. I can't tell what it is - it sounds vaguely like wheel bearings, but somehow different. The front bearings and a trans drain/fill was done by an independent shop 6,000 miles ago. That shop says the noise is the transmission and definitely not the bearings. My Toyota dealer says the noise is the bearings and definitely not the transmission.
Here are two videos I took this afternoon, which seem to more or less capture it, though it does sound a bit different recorded on a phone than in the cabin:
(this one has a clearer example of the noise)
Background:
I didn't have any complaints with the car until just before the 200,000 mile service was due, when I started hearing front bearing noise (I've had bearings done in about 5 vehicles, so it sounded pretty obvious to me). I brought it to the dealer and was quoted an outrageous amount for front hub assemblies (they told me they couldn't do the bearings, only the whole hub assembly), sway bar end links, alignment, transmission flush, tire rotation and the engine top end service.
I got a much better quote from my local mechanic who I've used for about 3 years, so I had him do the work. This was back in June, at 212,417. He said that they'd never done the flush on a Prius transmission before, but they had the shop manual and were sure of the procedure, and that their Valvoline rep confirmed the correct fluid, and gave them a written warranty in case of any problems. He did note that "a fair amount of metal shavings came out with the old fluid" when they did a drain and fill (not a flush). He also told me that the tires were worn unevenly so I could expect a bit of road noise after the rotation and re-alignment. They an oil change, sway bar end links, front bearings, tire rotation, alignment and reans drain and fill with Valvoline Max ATF, "Toyota Type WS fluid spec." He told me the same thing about the front hubs being complete assemblies, and the part he listed (PBR930641) appears to agree with that.

Very hard to describe this sound but it is coming from under the hood and lasts for about 10 seconds.

Have been driving my Prius with no issue all week. I leave the car home and take my wife's vehicle, while she drives it today without incident. I come home and hear the car making some strange beeping noise (NOT the anti-theft alarm, different). I hop into the car and try to start it, and the check engine and ABS lights come on for a second before other lights in the speedometer area kinda half come on. The gear indicator comes on and has boxes blinking on all of the letters.
The MFD never comes on.
It appears to be the 12V battery dying. The car has 150k miles and I have never replaced the battery, so it seems I was way overdue for this.

I have a 2008 Prius with 106,000+ miles on it. It was running fine till 2 days ago, I didn't start it yesterday and today when i went to start it, I get the Hybrid System Malfunction light, along with check engine, the red triangle and TPMS light. The gas engine tries to start up, then 1 second later makes a grinding noise and turns off.
I am in Toronto and its cold, but not THAT cold yet. So I am doubtful its temperature related. I checked the fluids and they all seem to be sufficient (engine oil, radiator fluid, power steering fluid). I didn't notice any leaks under the vehicle either.

I own a 2005 prius. It is stock and i recently had the check engine light pop up as well as "problem" when car was started and 2 lights with exclamation point, one on a car and ones in lil brackets. I believe it is called a "hybrid malfunction light". Well one day they all pop up and about 3 days later theyre gone. Only thing i did was fill up the tank, when they came on only 1 bar was left on the tank. My question is should i still take it in to see whats wrong with it? and what could of caused both lights to come on?

I am wondering if there is any way when I turn my car off that the cig/12v? outlet will still work? I have a 19 month old and we have a portable dvd player that he watches in the car and it is plugged in, when we stop for something and one of us run in a store for something we like to keep him entertained, but if I turn the car off it kills the power. How to keep it on, vag-com?

The DRLs in my 13 are 12v or a lesser power supply? Planning out my retro fit and wanting to do something different DRL wise but need a 12v supply, I know the headlights themselves are turned down some and can be adjust via VagCom.

I drive a 2005 Camry SE. In the mornings, when I start it up for the first time, my engine almost...growls. That's the only word I can think of. Not even growl. But instead of purring like a kitten, it purrs like a tiger . And it's only when I first back it out and then take off. Once it's good and warmed up, it drives and sounds perfectly. Shifts beautifully.
And this morning, I let it warm up for awhile and it didn't make any noise when I took off.
I talked to my coworker about it and she said she had a similar issue with her 2004 Saturn Vue and it was something about a manifold, but couldn't remember what it was called. And she said her mechanic was able to fix it, but only temporarily and then told her it would cost her big bucks to fix it permanently.

About a two weeks ago, I had a CEL pop up. I brought it in to the stealership to get it scanned. I don't recall what the exact code was, but the description was something to the effect of "Cooling System Performance." I hadn't noticed that the engine temp was any different than it had ever been, so we kinda figured it was just a bad sensor. We popped the hood just to take a look at things, but he didn't really notice that anything was off. I thought the engine sounded a little difference. It wasn't idling rough, but there was a very subtle ticking noise. He didn't think anything of it. So he cleared the code, and sent me on my way.
The code came back a few days later, but disappeared about a week ago. Since then, however, my .:R has been feeling a little different. Like I'm losing torque. The ticking noise has become distinctly louder, although I can only hear it when I pop the hood. Last night, i was listening to it, and there are two separate noises, coming from two different locations. One is coming from the left side of the engine, most likely from one of the belts. The other is the one that worries me the most, as it's quite a bit louder. This ticking noise seems to be coming from the engine itself. The longer I let the car idle, the louder it gets.
One of my friends took a listen, and he suggested that it could be a blown piston ring. This would explain why I'm losing torque, but I haven't noticed any blue smoke coming from my exhaust.

I have a 1999 BMW 3 series, 112K, 5 speed, immaculate condition, only full synthetic oil used. After a cold start - even today at 55 degrees - I get a strange noise from the engine compartment which gets louder according to RPMs. The BMW dealer replaced the oil separator for the motor ventilator and some of the respective hoses and valves associated with it. They also checked the oil pressure when the motor was hot and cold and advised it's fine; however, the noise is still there. (A different BMW dealer service advisor said, just after hearing it, it was an oil pump issue.)
On an unrelated note, when the motor is warm and I'm in stop and go traffic, the idle speed will sometimes go up and down (500 RPM - 900 RPM), and when it reaches 500 or so RPM, it dies. The car always starts back-up right away. Spark plugs are new and I used OEM BMW spark plugs. My thoughts are the idle air control valve.
Otherwise, the car is great; yesterday I took it on a 250 mile RT highway trip without any problems.

When I accelerate a strange noise appears to be coming from the passenger dash.
Sounds like some kind of baffle or low rumble sound it only does make the noise under acceleration.
