I hear a distinctive electric motor noise similar to the electric antenna noise in our 4Runner , almost always immediately after applying the brakes (no matter whether hard or soft). The noise lasts maybe one or two seconds.
View 17 RepliesWe'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.
View 19 RepliesI 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.
View 9 RepliesMy Prius C II is at a little over 6,000 miles. I've noticed when I'm accelerating from a stop using the electric engine, that at around 11-15mph I hear a clicking noise coming from the left hand (driver) side of the vehicle.
To hear the sound my windows have to be down and my stereo not playing.
Is this clicking sound while accelerating normal? I know there's a clicking sound that happens when I start my car and when my car sits after parking for a second but this clicking noise sounds like its coming from the front left hand side... not inside the cabin.
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.
View 11 RepliesMy girlfriend just picked up a 2007 Prius Touring, 78,000 miles, original owner. It was a private sale and I took a look at it for her. I'm just learning about the Prius and stuff to look for, but everything looked good on it to me. After purchasing it she noticed a noise coming from the drivers side dash. I searched here and saw that dash rattles are common, but this sounds more like an electric buzzing/whirring noise. The duration of the noise is always about 2 to 3 seconds in length, then it stops. There doesn't seem to be any common factor for when it occurs. Is there anything electric on the drives side dash (far left side, closest to the window), that might be making this noise? It's not super loud, you can't hear it if the radio is on.
View 4 RepliesJust 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.

View 1 RepliesI'm new to satellite radio, and I'm starting to really like it. However, I've seen many people with the same issue that the radio looses SAT signal very easily. Most SAT antenna are flat. Does the Prius use the mast for SAT radio, or is it inside the base of this? Need to get a better antenna that just screws onto this base?
View 2 RepliesI'm trying to lower the rear part of the headliner so I can replace a broken antenna base. I've read the detailed photo instructions posted on this site. I've been able to dislodge all of the parts covering the rear section of the headliner, including the dome light, but I can't get enough clearance unless I also remove the two rear grip assists. I'm flummoxed trying to remove the grip covers and sub-assembly. The official instructions are confusing, and the dealer tech could not explain it in a way I could understand. See attached diagrams. I can't figure out how to use the screwdriver to release the grip covers.
View 1 RepliesI have a 2014 super duty extended cab truck and at times I get a vibration noise which seems to come from somewhere around the antenna. The little rubber flapper at the base seems to move and isn't tight against the metal. Is this causing the noise...
View 4 RepliesI confirmed that my trial subscription to XM satellite is active, but I get no reception. The antenna light on the dash keeps blinking. AM/FM reception is fine.
View 3 RepliesAfter I brake and partially release the brake pedal (not completely letting off) so I can cruise a little further, sometimes I have heard a quick three raps or thumps. Normal?
View 5 RepliesMy mom has a c-3, today while she was out, pulled out of a parking lot at slow speed, went to stop at the traffic light and all she hear was a 'grinding' noise and had no brakes. Luckily she has thinking ability and used the parking brake to stop. She pulled off when able but then the brakes were fine. I'm a gen III driver.
View 7 RepliesI am a fairly new Prius owner. I have noticed that when I get on the brake, I will hear a sort of winding up noise, or a noise like a very small motor running for just a few seconds. It seems to happen every time I first get on the breaks when moving at a speed above 25 mph, and I can interrupt it if I take my foot off the brake. I kind of thought maybe it was something to do with the regen brake system, but I wanted to make sure it's not an indication of an issue.
View 5 RepliesI believe this is where the noise is coming from. I get a delayed tap noise when I hit the brakes. If I lift my foot off the brake and hit it again I might not get the noise. It seems forward momentum is need to "reset" whatever is making the noise.
Also.... Right turns at 25 mphs I can hear a rhythmic woob woob woob.
Accept for the tap noise the woob woob woob is hard to hear unless I have a passenger, more so if the passenger is in the rear.
I can't run this Prius into a dealer like I can in the states. I've had this Prius in the Republic of Panama since 2007. They just started selling IV models. This is possibly the 1st Prius in Panama
I had the pads replaced about 25,000 miles ago. There's 106,000 miles on the car.
I step on the rear bumper and bounce the car. The suspension sees stiff/normal. I don't hear any that might be loose.
I have Toyota Prius 2006 with about 58k miles. For the last 12-16 months I encounter the following problem: when I press brakes, I hear knocking noise. It doesn't happen every time, but when it does it only happens when I press the brakes. Once I brought my car to a Toyota dealer and waited for an hour until my car was taken for a service. Mechanic found no noise. I tried to produce this noise but my car didn't want to cooperate. I don't see any messages on a display screen. It happens with power on/off and pressed brakes. What the knock is and how to get rid of it?
View 2 RepliesI have just purchase a used one 2 weeks ago. I bought it from a local dealer (Longo Toyota). After I got the car home for a day it started to make noises when i brake. If the brake pedal is depress about half way it will make a squeaking noise when it comes to a stop. So i bought the car back in to the dealer and all they did was flush the system and reboted the computer. They said this is normal for some pruis to make a noise when the vehicle comes to a stop and it should not be a safety concern.
View 19 RepliesOur gen 1 has developed a (currently minor) noise issue when braking. I'd like to sort it out before it becomes serious.
The brakes are still strong, and the regenerative system appears to be working. When the brakes are applied (even gently) there is a pulsing raspy sound, seems like it is coming from the front, driver's side. It is more rapid at higher speeds, and louder during rapid deceleration. I guess I'd call it 'grinding', although this is much less unpleasant than the classic 'grinding brakes' I've heard on other cars.
In any other car I would figure a warped rotor or worn out brake pad. But I had imagined that the regenerative system handled light braking, and conventional brakes took over beyond a certain threshold. Now I'm hoping they work in tandem, even on gentle braking and this is just a boring, simple pad issue.
Gen II Prius at 175k miles is making a new clicking sound. One solid brief single click when the brake pedal is pressed. It doesn't happen every time (about half the time?) but can be heard the loudest at approx. 10-20 mph (possibly because road/wind noise is at a minimum at this speed). The work below was done at my local independent hybrid mechanic at 151k miles but since then I have only done oil/filter changes and checked oil levels, which have looked good.
Turn rotors, pack front bearings and replace pads, gold brake pads, rear brake service, performed induction service, cleaned throttle body, added tank injector additive, 3in1 induction kit, transmission service kit, transmission fluid, transmission service package, performed coolant serviced, drained and refilled coolant system, flushed out contaminants, refilled reservoir, coolant service, inspection, replaced drive belt, drive belt.
Parked Prius making awful sound from brakes. Could it be Suspension? However, I am not sure how to describe this one.
