Prius (2004-09) :: Grinding Noise In Front End?

My Prius has developed a disturbing noise over the past 2 weeks. I believe the noise is coming from the front, driver's side. The faster I go, the louder the noise. It begins shortly after accelerating and doesn't stop until I stop the car.

I didn't think it was a mechanical noise, but now I'm not sure. I feel a slight vibration in the accelerator pedal while the car is making the noise. I'm wondering if this is something in the axle, wheel bearing, transmission, or what.

Prius (2004-09) :: Grinding Noise When Braking At Low Speed

Bought my Prius (2005, with 160K miles) about a month ago and since I've had it I am hearing a metal on metal grinding noise when braking at low speed. How loud the sound is depends on how hard I am on pushing on the brakes. One of my co-workers has the same model and said that his does not make that sound. Not sure if its just because it has after-market brake pads or something? This noise only occurs when braking at low speeds (below 10 MPH) so I assume its an issue with the front brakes.

Is this something I need to get looked at by the dealership? I had a local mechanic that worked on my old Honda beater take a look and he said that the rotors and brake pads looked new and wasn't sure why they'd make noise.

Prius (2004-09) :: 2007 - Grinding Noise When Braking

So my dealer diagnosed my 2007 Prius with a transaxle issue, but what bothers me is that it doesn't make the sound all the time. When I brake lightly, there is no sound and when I brake heavily there isn't either. It is only when I do a medium brake above 7 mph of course and around 20's mph range. I am hoping for something besides the transaxle...maybe a wheel bearing...anything.

Prius (2004-09) :: Grinding Noise Coming From The Front

I've got a 2004...it has 90,000 miles. For about the last 5000 miles I've been experiencing - only a few times a month, and totally out of the blue - a grinding noise coming from the front (i think left). This happens when I'm traveling at about 55-58 mph (never at lower speeds). It even happened once when the cruise was set. It gets pretty loud, and i find that if i pull over and stop for a few seconds, then keep going, that it stops. In other words, it seems that breaking to a stop disengages whatever the cause is. Also, no warning lights come on at all...like i said, it happens totally out of the blue. No, it's not the wheel bearing.

Prius (2004-09) :: Whirring / Grinding Noise In Dash

I am experiencing this whirring/grinding noise:

Which is the same as this thread : Grinding Noise from Dash | PriusChat

It occurs intermittently when starting up the car, though if I then turn the car off (as in my video) the noise continues.

On that thread the vehicle was in warranty and was fixed by replacing the MFD touchscreen. My 2006 UK Prius is (I believe) out of warranty, and the touchscreen/MFD seems to be working fine. Is there anything I can do preventative on this?

Prius (2004-09) :: Inverter Generator Grinding Noise When Braking Above 7 Mph?

My car was making a weird grinding noise when braking above 7mph. I did the neutral brake thing and seems to go away sometimes. The dealership said it needed new rotors and brakes, so I went ahead and did that with them, then called me to let me know the sound did not go away. Now they are stating my grinding noise is coming from the "inverter generator" which is what they said was the transmission. I am just curious why this goes away sometimes and if it's related to my previous issues with the car.

Prius (2004-09) :: Code P0A92 Accompanied With Grinding / Crunching Noise

2008 Prius with 105k miles was throwing code (P0A92) and had accompanying grinding/crunching noise. Intermittently, The HV battery would drain down and the car would have difficulty starting. The car was stranded in the middle of a 2,000-mile trip in October after extended use of the A/C, and was left at a friend's house until February.

After weeks of arguments with local Toyota dealerships, who refused to listen to Toyota's national service representatives and demanded that we purchase a replacement battery for $3,000, I purchased and installed a HybridAutomotive grid charger. The Prius started and drove, but lost power about 10 miles into the drive back. Being in a hurry, we resolved to return with a trailer and tow the car back to my shop.

A replacement, low-miles transmission was installed per directions in the FSM. There was some trouble getting the inverter pump to bleed (I ended up taking off the return hose & pouring coolant backwards through the pump), and I had to swap in a spare 12v battery due to the old one being discharged. The car showed codes C0205 and C0200 (left front wheel speed sensor signal malfunction, right front wheel speed sensor signal malfunction), but no other issues.

About two weeks and 3,000 miles into the transmission swap, the battery I'd swapped in would no longer fire up the computer. A test showed the battery I'd swapped in (which I purchased in 2005) was only outputting 300 CCAs (out of a rated ~1,000). The Prius accessory battery was charged and reinstalled. The battery started the car, but would often need to be charged overnight in order to start the car (even though it would pass voltage and CCA tests). When the car won't start, attempting to jump it off another car doesn't work, and the battery had given readings as low as 10.5 volts, indicating a bad cell.

Yesterday, I had the car's owner run the in-car test procedure. Voltage was 12.3 without load, 12.0 with load. The third test could not be completed because the car shuts down. As the voltages were slightly low, the battery was replaced under warranty, but the car is exhibiting the same symptoms with the new battery. I'm now suspecting a bad inverter and/or failed inverter pump.

Prius (2004-09) :: Grinding Noise In Engine Area - Car Started Stuttering Like Out Of Gas

04 with 200k miles, car started stuttering like out of gas, when stopped there was a grinding noise from engine. Took to dealer on trailer, when it was taken to the mechanic all problems went away. Changed oil looking for metal chips, none. Did computer upgrade which was the only code on the check engine light.

Drove car for two days on short trips, four or five times 20 to 30 miles. Ran great. At around 40 miles on next day same problem. No lights or codes of any type. Carried to dealer again, they said they were not sure if it is the engine, transmission, or something in between. I was told they would have to take it apart to find out and the least amount it would cost is $5,000.

The grinding occurs when the engine is running only. when revved up it is louder, at idle the noise changes while sitting in park, louder quieter etc. when driving on electric, sounds perfect. (no sound at all)

Prius (2004-09) :: 2005 - Clunky Grinding Noise When Backed Out Of Parking Spot

I'm not sure what the noise is, but it sounds expensive. Backed out of parking spot, started making an awful clunky grindy noise. Put in drive and more noise but no go. Put in neutral, still grinding but stopped after a minute. Pushed back into spot, waiting for AAA. Interesting it would not go into park from N until the grinding stopped. No lights on dash interestingly, except the snakes chasing your car (traction?) light flashes intermittently while it's grinding.

Prius (2004-09) :: 2004 - Red Triangle Came On After Changing 12V Battery

I have a 2004 Prius, the Red triangle came on intermittently and went off so I changed the 12V battery last night, after changing it the red warning light went off and everything seemed okay. Today while driving, the warning light came back on. I checked the battery voltage via diagnostic mode on the cars computer and the specs are what they should be. I noticed the following error codes in the computer:

01-D5, Sub-code: 190-30-8
01-DC, Sub-code: 190-B7-8
01-DC, Sub-code: 1C6-4D-F

Not sure if these are what is causing the problem.

Prius (2004-09) :: Triangle Show Up And Just Would Not Go Away

My 2006 has about 67,000 miles on it. The other day it began to behave in a very strange way. I had the triangle show up and it just would not go away. I checked all the fluids and they were good. I did notice that there was a new icon I had never seen before. It looked like it was an curved device with a thermometer attached. When I looked it up the suggestion was to go to Toyota right away. So I decided to drive over. As I drove I could hear the fan from the back seat coming on. It was going very fast, so I guessed that the traction battery was overheating. The car would barely drive, no power. Even when I floored it there was very little acceleration.

I got it to the dealer and they gave me a loaner because it the car was recalled due to the accelerator pedal. Later in the day I got a call saying that a couple of ECUs needed to be replaced. The next day I got a call saying the traction battery was bad and would be replaced under the long term warranty. They said I also needed an aux battery. I knew my battery was not charging up to better than 10 1/2 volts dc. They said it would cost $300 installed, so I said I would get back to them.

Prius (Gen 2) :: 2004 - Red Triangle Warning Light Came On And Went Away?

The red triangle warning light on our 2004 came on and went away again It has 100k miles If I take it to the dealer can they pull some codes and figure out why it turned on We have to drive the car to 600 miles for the upcoming weekend and I don't want to be stranded on the side of the road The car has 103,000 miles We just replaced the 12v battery so I know that is OK

I also saw the following things to check. Is there anything else we should check?

1 - Are any warning lights on besides the red triangle? For example, the red BRAKE light, the amber ABS and VSC lights, or the amber circular icon?

2 - Did you check the brake fluid level? If low, buy a new container of DOT3 brake fluid and replenish as needed This fluid will dissolve paint, so do not spill it

3 - While you are at it, check the radiator and inverter coolant levels by looking at the translucent reservoirs behind the radiator and next to the inverter If low, fill with Toyota Super Long Life Coolant
