Prius (2004-09) :: All Of A Sudden Car Started Making Horrible Knocking Sound
Jan 18, 2016
I was driving the other day, and all of a sudden it started with this horrible knocking sound. I have never heard the sound before. I remember back in the day, with a 67 buick rivera, that if the oil got low, the engine would knock, and this kind of sounded the same, but more high pitched and clicky. I checked the oil first thing and there is plenty in there - in fact, I had just checked and put oil in it about two weeks before.
I have not always kept up with the oil changes, and sometimes the oil level was pretty low. My sons tell me that the sound seems to be coming from the top of the engine, and it's probably toast, a rod knock. I parked it, and figured i will get it looked at in a few months, when I'm better able to pay for diagnostics.

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.

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).

The other night I was going up the mountain and while going it started making a clicking noise..probably from no oil..We had been told from the dealership there was a small leak but nothing to worry about at the moment.We tested it and it wasn't leaking visibly but I guess with it getting cold out the hole got bigger and we didn't notice so all the oil leaked out as we were powering the lil car through the mountains..Needless to say on the cruise down it started shaking i saw some sparks and I think the rod went through my engine block and we broke down. It's completely dead. The car has right around 200,000 miles on it and has always been very well taken care of.I just traded my dad the car about 7 months ago for my 4-runner cause of gas prices..I moved across the country and of course have had NOTHING BUT PROBLEMS since day one.

My '07 started making three very quite beeps while driving, happens about every 15 minutes. It sounds like it might be coming from under the passenger seat. Mileage on vehicle 168000.

The issue is, when driving at low speeds, especially after coming to a stop, I hear this intermittent knock that comes from the rear of the vehicle. I am not sure if it is coming from the outside or inside, but it really sounds like it is coming from the chassis.

I started up my 2004 v8 phaeton with 49k mies for the first time in two weeks and it made an awful squealing sound that seems to be coming from the front of the engine. it also seems to be idling very roughly, this may or may not be related to the noise. it has never made this sound before and i am scared to drive it until i get an idea of what it is. i am afraid it is the timing belt and the i will ruin the whole engine on the way to the dealership.

This morning when I heard some knocking from the ICE and found NO oil on the dipstick. You wouldn't BELIEVE the drive the car did the day before when I lent it to my sister-in-law). Anyway, I thought the red triangle would illuminate with low oil. I can't seem to get the light to illuminate. Even when I first start the car and "all" indicators light up during the test. I'd say this is one important light. We've had the car less than a month and I could swear that when we first got it I saw the triangle at start up.

My 2000 Toyota Corolla is making a knocking sound that gets worse when the car is in idle and in drive. I have a feeling that it is dying, but is it unsafe?

Car is in for knocking sound made when you are stopped and you turn the wheel quick from left to right. Also does the same thing when you hit a bump. Dealer is saying it was always that way I say bs. 2008 prius.

Just bought an 05 yesterday. It has 193k. The steering seems to have some play and an occasional clunking sound when turning the wheel. I do not know of a dealer or an independent shop that will give me an honest opinion or quote..

My 2004 Accent transmission with 145k miles all of a sudden started slipping while driving. It would be fine until i needed to slow down and then step on the gas again. It wouldn't catch right and it would slip. At first the pull of the slip was very slight and at times now it is very rough. My check engine light does not turn on when it slips slightly, but only when it has a really rough slip will it turn on. I had it checked at the local advance auto parts and i was told it has a 4th gear ratio that is off. The only thing that confuses me is that when i turn the car off and on it resets and works fine, that is until it slips again. If i drive carefully it usually wont slip. Could it be an electrical problem?? I changed my speed sensor when my car had about 132k miles because it went out, i replaced my ignition coils, new spark plugs/wires, tranny oil change, and filter change.

Today in the morning it was slightly cold so I turned on the heat in my car. The fan started making a loud whistling sound and in about 2 minutes it stopped. Is this a sign of a bad fan?

Had drivegear springs installed about 7 months ago or so and recently the front started making a swoosh sound when going over bumps. Took it into the dealership and they told me they tightened some chassis bolts. So I take it home. Problem is still there. So I go back and let them know. I go for a ride along with the manager and he tells me the noise is normal. So now it's not a matter of it being covered under warranty but more of is it a problem at all?
I remember someone telling me it might of been the control arm bushings. I need rubber ones or something. How I should approach this so my car doesn't sound like a 1980's chevy.

About a month ago my Touareg started making loud rumbling noises at highway speeds. It sounds and feels (it makes the whole truck vibrate) like you're driving on the "wake me up bumps" that are on the shoulder. Some times it last for 30 seconds and other times it goes on for the whole trip. It's driving me crazy; however the dealer can't reproduce the problem so they think I'm crazy. It doesn't do it all the time, however, the only common symptom is it happens at speeds above 65 mph. It has happened when it the car was cold and hot, cruise on and off and variable highway speeds. The transmission was replaced right after I received the car due to a malfunction, so the dealer doesn't think this could be a second faulty transmission.

The power locks on the front right door started making a ugly sound. I disassembled everything including the actual electric actuator and found that the problem is caused because one of the gears that got a teeth broken.
Now, I forgot to take a picture before I put it all together, but it was white gear about one inch in size with a little square thingy in one side that moves the actual lock.

So here I am with my 1996 Dodge grand caravan that I purchased new in 1995 for a whopping 30k. Yeah hind site is 20/20 skip forward to mile 102k transmission fails completely. Had to have it towed in to shop, rebuilt tranny put in... skip ahead another 4 years to mile 173k and transmission fails again. Again on a tow truck to the shop and ANOTHER tranny rebuild. So now I am at mile 182k and transmission is making a horrible shudder and I have moved across the country away from original shop that did last trans repair (who says they only warranty if I come back to them) and I am possibly looking at another repair or replacement. What is the deal with these vans?

Last June I took my 2001 Audi A4 off the road since I bought a more fuel efficient commuter car but I wanted to keep the Audi in the family until my oldest son started driving. That day has come and I'm making the car drivable again. I pulled the battery over the winter and kept it on a Battery Tender. I put it back in over the weekend and the car started up up and runs just fine. The only problem is that the rotors are extremely rusted and make a horrific grinding noise. Is there anything I can do to remove this rust? I assume I can just grind it off with the brake pads but that can't be good for the brakes which, if I recall correctly, are fairly new.

I just turned 3000 miles on my C. I started the car and the engine chugged and knocked like I have never experienced. I turned off the engine and restarted and no problem.
