Prius (Gen 2) :: 2007 - Knocking Noise And Brake Locks Up
Dec 28, 2011
I have a 2007 Prius that was a salvage rebuild. I have owned it close to a year without any issues, Now I have noticed that when its cold, and I press in the brakes, I hear a knock from the rear, and it feels like the brake locks up, it only does it as i am coming to a complete stop, so for instance, going from 60 mph to 40 quickly, its fine, but if i slow down to a full stop, I hear it, and feel it, then it takes a second once i press the accelerator to go again, like, it takes it a second to let go, now if i drive it around for 5 minutes or so, that goes away completely...?

Scion TC for Camry SE 2007.
I changed the front brake pads and resurfaced the rotors. After putting everything back together, I took the car to test drive it. The stopping power is fine and there is no squeaking or robbing sounds. However, when I apply the brakes at lower speeds moving forward there is knocking sounds the comes with the tire rotations. What is the reason for this sound?
This is my second time changing the pads and rotors, with the first with no issues. I put grease between the shams and the pads, and I sprayed the rotors with brake cleaner before the installation.

This has happened twice now, about a month ago and then again today.
I was stopped at a light with my foot on the brake. There is a clunk noise, then the indicator light comes on.
The first time I tried to go, and the car stayed put. I hit the parking button, then went back into gear, no problem.
The second time I just put it in park and then back to gear. No problem.

It's a 07 prius with 65k miles. I realized that it is making this squeaking noise while going over bumps "ONLY" when the brakes are applied.
I have 2 toyota dealerships checked. 1st dealer said no noise and 2nd dealer also said no noise... then, i requested to drive with the mechanic and he somehow heard the noise while I am in the car.
I posted a youtube video w/ iphone video if you feel like hearing the noise...

I have a 2009 AWD Santa Fe with a little over 43K miles. Over the past few months it's developed a knocking noise that is most audible from the front drivers side area. The knocking speeds up or slows according to the car's speed, and appears somewhat louder when the steering wheel is turned. My initial suspicion from my surfing here is either a CV joint or wheel bearing.
I took it to the dealer that sold it to me and am getting increasingly frustrated with their work. The first irritation was yesterday when the service advisor called to say the problem was corroded rear rotors and brake pads; both wear items not covered under warranty. Though skeptical (since I was hearing the noise coming from up front, not from the back) I authorized the $300+ for turning the rotors, replacing brake pads and flushing the brake system.
When I showed up to retrieve the car I was told it'd been test driven and the problem was fixed. I asked the tech specifically whether he'd checked the CV joints and he assured me he had and they were fine. Upon driving away it was immediately obvious the knock was still there. Back to the dealer. I had the tech drive it with me in the passenger seat. He acknowledged he could now heard the knocking, but claimed he previously couldn't hear it over the horrible loud squealing from my rusted rotors; nor had he heard it on his alleged post-fix test drive. The problem with that is I've never heard this claimed horrible loud squealing, nor has my girlfriend, nor have any other regular passengers.
Back at the dealership the situation escalated when the service advisor, in defense of his tech, also claimed the horrible squealing rotors had drowned out any other noises. The problem with that is he admitted he'd not come along on any of the previous claimed test rides, and claimed to have heard the horrible squealing rotors only while the car was in the shop and/or up on the lift while the tech was turning a rear wheel by hand. Err, if the car was not driven any for distance or speed, of course you wouldn't have heard any knocking up front.
Yesterday evening I got a call from the shop advising the problem had now been diagnosed as a bad wheel bearing, front driver's side. I was assured it'd be fixed and ready this afternoon. All well and good. I showed up this afternoon and the service advisor stated the car was just getting buttoned up and we're going to test drive it. Fine, I'd like to come along on the test drive I said. He agreed, asked me to sit in the waiting room. In a few short minutes though - not long enough IMO - he came back out to advise the tech had just test driven the car (without me?!) and the knock is still there.
As of this writing I have no info from them as to what it might be. I left the car with them and asked the service advisor to have the tech(s) double check the CV joints. He got huffy with me and declared that if if the tech said he'd check them, there's no need to do so again. At this point I'm not sure whether I can trust this dealers' service department. I don't think the service advisor is being honest with me - I think he's been caught in a minor fib re: test riding and is compounding the situation by sticking with it.

I have a 2007 Fit, and just recently started to have my car rumble, specifically the break pedal, when I break. We got new breaks about two years ago. I'm just wondering what it could be. Another thing is I was driving and some (explative) person decided to pull out in front of me when they really shouldn't have. I slammed on my brakes and had a grinding noise and feel to my car when that happened. Since then when I'm driving slow I get a knocking feeling against the foot area of my passenger seat. What could this be? It is kinda hard to look underneath the car since it is so low so we can't easily see by the wheels or Axel area.

My new SANTA FE has merely covered 10000 km. The vehicle is running fine except a very irritating loud knocking noise from top of front windshield area. The noise is generated as soon as vehicle goes over a minor irregularity on road or even if you make a sharp right or left turn.

My 2007 CM Santa Fe 45K miles began acting up intermittently. We have owned it 5 years from new and never any issues whatsoever. My wife told me that first thing in the morning it made a horrible clanking noise and the entire car shuddered so she shut it off. Then it cranked and ran for days normally. The other morning I got in it and cranked it and man, it sounded like rods knocking, pistons slapping the crank, it was awful. Actually it sounded like premature or off time detonation, the engine would not idle and would die.
After a couple more tries the engine cranked and ran smoothly but with increasing idle speed and after two instances of normal cranking but idle increasing ever upward (same morning in sequence of 10 minutes or so of trying) I called AAA and had it carried to the dealer afraid oil pump giving out, timing belt jumped, bad crank / cam sensors, who knows? Oil was changed 5K ago with Hyundai toilet paper filter.
Anyway dealer found a code, something about engine torque excess - who knows - it wasn't causing the horrible cranking idling banging noise... did some ECM/ECU update, and repaired a TSB for the passenger side Airbag seat detector. They kept it over night and still could not make it occur.
My wife is really worried because honestly it sounds like it's going to throw a rod or something *I know it doesn't have them*. It's just a horrible gut wrenching noise. Dealer mechanics could not find anything wrong and they kept it overnight to crank it cold, and when we picked it up today it cranked fine.... She can't trust it anymore.

I am getting a loud knocking noise from the engine on my Santa Fe. The car is very low mileage of around 51K and has regular service and oil change.
Not sure what has caused this but there is a loud tapping/knocking noise coming from the engine. Have got it locally checked with the garage and Hyundai Workshop also but both have suggested that Oil levels are appropriate and they need to open engine to investigate more.
At a higher RPM the sound becomes more loud and recognizable.

I have a 2010 Santa Fe V6 2WD. When I rock my steering wheel back and forth, I hear a knocking sound when engine is off. Sounds like maybe the steering gear box has play in it.

I tried to start my 2005 Prius this morning and a high pitched noise started (the same noise that happens when you hit the power button without having your foot on the brake). The emergency light was locked on as well as a message on the display screen about setting the emergency brake. This has happened one other time an after about two minutes the noise stopped, and I was able to start the car. This time the noise and lock remained for about 20 minutes until we disconnected the battery in the back. We re-attached the battery after we removed the ignition key and after a few moments all the power seemed to be gone. The fob doesn't work at all and the electronic lights and dash flickered and faded out. Our gut instinct is that the battery needs to be replaced. Was it the 12V battery?

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?

I started my Gen 4 Prius two yesterday and got out to adjust a bolt on the rear license plate and noticed a strange sound as the ICE in high throttle began the warm-up cycle- a sound like water sloshing around in the cat converter (or somewhere upstream?). Other new Gen 4 owners please check this and see if you hear this on startup. It is not regular enough a sound to be engine knocking, but literally like water churning. Not loud enough to hear from anywhere but right near the lower rear of the car. Hear this on new 2016? My Gen 3 never had this sound.

I recently bought a 2007 Prius that is making a rather loud knocking noise that has me a bit perplexed. I know the noise is not normal as my 2005 does not do this.
The noise only happens when the ICE is running and the car is in drive
If the car is in park and you rev up the ICE the noise is not present. With that said I do not think the noise is isolated to something in the ICE as I think it would be present when revving the engine in park.
However is you put the car in drive and step on the brake (to keep the car stationary) while lightly revving the ICE the noise is present. The noise is present every time the car is in drive and you accelerating, even with the lightest of throttle.
It does not need to be under excessive load and with that said I am certain it is not spark knock/per-detonation of the fuel nor does it have the "pinging" sound like a spark knock.
If while driving down the road and the ICE shutdown down while driving at lower speeds the noise disappears. When the ICE starts back up the noise reappears.
