Yesterday, while at the store. I started my 2004 prius and the engine was making some crazy knocking noises. I went to auto zone and pulled the codes. It said random cylinder misfire and misfire on cylinders 2,3, and 4.
View 1 RepliesRecently I started to hear engine pinging/knocking-like noise when the hybrid battery level becomes low like two bars and the car starts a charge cycle. I also hear it occasionally when I accelerate on uphill. Is this normal or should I take it to a mechanic?
View 2 Replies2000 Pontiac Grand AM SE 2.4L DOHC 129,000 estimated miles. After arriving home from the highway, I took notice of a noise coming the engine. Popped the hood just to hear the knocking noise. I had a mechanic from a dealership listen to it. His said it was a lifter or two. Doubtful of what he said, I got a second opinion and this mechanic said it was a rod. So, my question is this, can the rods be replaced without removing the engine?
View 3 RepliesI have a 2010 Sonata V6 that I bought new. It has a little less than 50K on it. I tried to start it today and it made a terrible noise then died seconds later. I popped the hood and then started it again and the engine was shaking violently in the engine compartment and making a terrible knocking noise. I had driven it 12 hours earlier and it ran fine. I called a tow truck and had it taken to the dealer but if I know my dealer, since it is Sunday they probably wont get to it until Tuesday. Also, this car has had the signature V6 valve cover leak that has been fixed 3 times. I noticed it was leaking again about a month ago and I have just been checking the oil and adding it as it needs it. I dont think the engine ran out of oil because I checked it before the tow truck came and it was between low and full.
View 2 RepliesI 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.
View 2 RepliesI havent had my 2000 taurus too long.... Last week a knocking noise started. It usually happens when I am turning but there have been a few times it does it when I am braking. It doesn't happen right away - just after I've been driving for at least 15 minutes or so....
I got this looked at last weekend at by a mechanic and they drove it and didnt hear a thing and supposedly things underneath looked okay. I can tell that things ARE NOT OKAY. Also, since this knocking started, my alignment seems to have gotten off a bit. I may be a blonde but I've had enough problems with past cars that I usually know what I'm talking about!!!!
it was warmer the day than it usually was so it dosnt make the noise as bad however there is usually a lot of clatter/knock from the engine when cold. does it at idle and while accelerating. it gets less once the engine warms up but has been doing it for a while. car has 93k miles and synthetic oil is used. there is also a metal rattle sound almost like a heat shield that is loose. idk if that is part of the engine issue or not. but it only happens in winter or when temps fall below 60 degrees. kinda hard to hear on the vid but its there.

View 2 RepliesSo my 2012 plugin was parked for about 3 days, and when I turned it on, heard loud knocking and the check engine light came and stayed on.
When switching the car on or off, I'll hear two taps/ticks that were not there before. Loud knocking is not there now.
What can the issue be? It was very cold and snowing.
Recently, when I start the engine (cold or even warm starts) I hear a subtle knocking noise that doesn't last too long but a few seconds. I figured that maybe it's because our area may still be using winter mix gasoline... but I'm not sure. Also, there's a rattle underneath the car when the engine switches into generating electricity with MG1.
This only happens after a start-up procedure (cold or warm). It stops when I push the gas pedal down a little bit (while still in park) then it goes into charging again, and by that time, it's stopped. I figured it may be a heat shield on the exhaust. It sounds more up in the front.
Also, when I start the car, the engine starts smoothly but then 1-2 seconds later goes into spinning MG1 which makes the car kinda sound like "vrrrrrrr---VRRRRRRRRrrrrrrrrrr...." .
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.
Sometimes when my car as sitting at an idle in either drive or reverse the motor starts to make a knocking noise from the back of the motor towards the firewall side on the top of the motor. I have a video. The car has 114k I just changed the oil I thought maybe it's low but it's not and hasn't moved since it was changed.
View 4 RepliesMy mom was driving to pick me up and she said that all of a sudden about half way here that the car started making a knocking sound and white smoke started coming from hood, the car was also trying to shut itself down while she was trying to pull over. It is a 2000 ford taurus with like 130k. I am so scared that it is the head gasket because my mom, myself and my daughter, and my 16 year old sister all share that car to get around. Is there anything else it could be besides that or is that probably what it is?
View 19 RepliesMy 2006 Prius makes this noise - like a groaning sound for about 5 seconds - when I shutdown the engine. Always happens when I am NOT at the dealership. Generally happens when the engine is hot. What this might be?
View 2 RepliesI've decide to replace the engine in a 2005 Prius. For whatever reason it went bad around 110,000 miles. It was making some noise and then went all at once. I don't know the complete maintenance history of the car, but I know it was pretty regular. I also know the car was driven mainly highway miles and on A LOT of dirt roads. So, the oil may have needed more frequent oil changes.
View 19 RepliesMy wife bought a new 2010 Prius Hybrid. It has consistently achieved 51+ miles per gallon. She bought it in June-2010 and at the 7000 mile mark (October?) called me concerned about a noise it was making under the hood. She described it as akin to the noise a playing card made when as a child you fastened it to the spokes of a bicycle. Chattering? It lasted 15-30 seconds and went away, before engaging in reverse or forward. A trip to the dealership was fruitless, an "intermittent episode" the diagnosis.
Now, nothing since until today. Same noise again, 12,000 mile mark, goes away in same timeframe, in park. Only today, through the course of several errands, her dash MPG indicator reads 39 MPG. She is waiting as we speak in the dealer lobby as they plug into the computer hunting for fault codes, etc. Having issues, especially an indicated dropoff in MPG seemingly in conjunction with such a noise?
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?
View 8 RepliesI have a 2000 F250 5.4 that has a ticking/knocking noise. After about 30-60 seconds of first starting the truck in the morning, the ticking/knocking noise appears. It sounds like its coming through the exhaust system and seems to be louder under the front passenger side wheel well. When I rev the engine up, it seems to go away. Does this engine have a cam phaser? Could it be timing chain slap?
View 11 RepliesThe 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.
View 8 RepliesI just bought a new 2015 prius a few days ago. After a couple of days of driving it around, I noticed this clunking noise that lasts about 2 seconds while the car's shutting off its gas engine when the vehicle is at a complete stop. It happens more frequently a few minutes after I started driving the car. When the car is coming to a stop and the 'EV' light is not on yet (only 'ECO' light is on), after the vehicle's made a complete stop, I start to hear this clunking noise (it almost sounds like the noise you hear when you press down your emergency break).
After this noise, I feel the vibration and hear that the gas engine's shut off. I talked to the dealership and they hopped in to hear that noise, and as always, it didn't happen. But as soon as I left the dealership, I hear it again. the car is normal when 'EV' light is on when its coming to a stop (no abnormal noise), but its only when the gas engine shuts off after the car has made a complete stop. And the noise is even louder when the vehicle is on a slope, either uphill or downhill.
I uploaded the video file ....
I've noticed distinct engine knocking noise under acceleration/load especially at lower RPMs on a '14 TSI. I'm at 20k miles and wondering if cheap gas from ARCO is the culprit.
