Prius (2004-09) :: Engine Makes Clattering / Knocking Noise
Feb 27, 2014
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.

My 01 accent's engine makes a clattering sound(sounds a little bit like a diesel engine) when it's first started in the morning. After warming up (in about 20 seconds or so) the sound disappears. My oil level is normal(last oil change about 4k miles ago with full synthetic oil. I normally change oil at 5k intervals with full synthetic), timing belt changed about 1 year(20k miles) ago. Should I be worried?

I have a 2001 Toyota Tacoma that has a knock or ticking in cold weather. The problem starts sometimes immediately after I start and other times it is only when I press on the gas in the cold mornings after a few min warm up. The noise goes away after 10 min. The question I am wondering is this:
1: could it be worn piston rings and the pistons are slapping the cylinder wall
2: is it an oil pump problem or a oil restriction issue
3: is it a valve guide issue
4: with the history of the 2.7 having exhaust manifold issues (poor manufacturing) could a cracked manifold be the issue
I change the oil myself, the oil filters have been OEM toyota, the noise has been going on since 60,000 miles, the truck is at 230,000 miles.

I'm new here and I am having issues with my Lumina. It is a 93 Chevy Lumina Euro 3.1L 6 cylinder and has 192K miles on it. It has had one owner for the past ten years that I know for a fact.
Here's what happened. I was coming back home (2hr trip) The brakes had started making that roaring sound on the way down and had gotten worse when I got ready to make the trip home. Okay so I know the brake pads needed to be changed. No big deal. Well going down the road at 65mph I round a curve and my car starts making this REALLY LOUD grinding clattering noise. It took me forever to get it stopped. I will still in the road and I needed to get it out bc it was right around a curve. So I put it in drive and it wont move. So I put it in reverse and it moves just fine with no problems and no noises made. After backing it out of the road I tried to put it in drive. It moved forward a few inches and stopped like something was binding it up.
So here's the problem.. it will move in reverse with no problems at all and only creeps a couple of inches forward then stops. The harder you press on the gas the more it tries to lurch forward but will not move.. like it's caught on something.
We changed the rear brakes on it. Discovered that the driver side rear rotor and caliper were broke beyond repair so we replaced those too. Still the same.. moves forward a lil bit and stops but will go in reverse just fine. We don't seem to think its the tranny bc it pulls hard and seems to not have any problems pulling.. but its like something is bound up somewhere. That is the best way I know how to explain this situation.

My 2005 Ram 1500 makes a knocking noise (like a diesel) when i first start it up. The colder it is the louder it is. Once warm it is quite and i have no performance issues.

I have recently noticed that my Azera makes a "knocking" sound right after starting the engine. It just about a dozen of fast short knocks one after another and it is gone after 2 seconds (like a diesel engine started on low temp. It appears more often when the engine is rather cold.

I have a 2002 1.8T with about 75k miles which makes a harsh rhythmic sound at idle after about 30 minutes of driving. If I tap the accelerometer to increase the rpm and release it goes away and is silent. Recently it also seems to be making the same sound when it starts but goes away as soon as I drive. The sound seems to be coming from the front lower right (passenger side).
I have changed the timing belt about 18 months ago (along with the water pump, tensioner, etc. using an ECS tuning kit) and it ran fine (seemed even smoother than before) but it had a small engine oil leak which my mechanic fixed. I think this sound started after he repaired the leak. I've left the car with him for a week and he just called and said it he couldn't figure it out but it could be an oil pressure problem but I have not had any issues with an oil pressure light.
I have had issues with the P0411 code over the same and have replaced both the secondary air pump and the combi valve but the code just reappeared and my mechanic says he has checked the entire system again and can't figure out what is causing the problem. Not sure if the two can be related but just thought I would add that. The car runs fine otherwise and I have always used synthetic and the large oil filter but I am beginning to think this could be a sludge issue (the noise).

My problem occured at beginning of 5,000 mile trek to pick up my wife at her Florida friends place and make some visits heading north. The solution (not done until yesterday at Lexus) is appearing quite often now.
In fact at the feet of my Service Person's desk was failed part which is a plastic cover under the car for the fuel tank which loses rubber dampening lead strip over time. Then it clatters in thw wind (especially at Hwy. speeds) and telegraphs up thru' door and frame channels to seem like it comes from roof.
I thought my hearing bad at detection when I found this out but apparently they have speant all kinds of wasted time with roof channels/ rubber strip replacements (which I had done on right side of car and had done left side of car yesterday before we figured this thing our)/power moon roof assemblies. The problem is under the car.

Since new my Prius V has had a metallic clattering sound that comes from underneath the car. This can be replicated when driving over lane divider dots on a quiet street with the windows down. To investigate, I put the car on ramps and looked around; I was almost certain the sound was coming from a thin aluminum heat shield that is just behind the engine. Tapping this shield made a similar sound to what I heard coming from under the car while driving over bumps and such. The shield is poorly attached with those "fun" push pin fasteners that seem to be liberally deployed all over the undercarriage. I decided to re-attach the shield with a judicious circular application of silicone under each of the holes in the shield and let it dry. The clattering sound I heard previously when tapping the shield was gone. Out for a test drive and still there!
I just had the first service done, and of course the tech couldn't hear it on his test drive. Unfortunately I was pressed for time, so I wasn't able to take a test drive with the tech. I will drive the tech around next time and demonstrate it.

My 2005 Prius shakes and makes a weird noise when I go to start it up in the morning. This usually only occurs from cold start in the mornings. Once I warm it up for ~2-3 mins all seems to be well. No CEL or anything of that nature. Trying to troubleshoot what the problem is with these cold startups. (76K)

I got in the car today and started it... I was waiting a few seconds for someone to get in the car (it was in the garage) and as soon as the engine kicked on there was a very very large long rattle noise i immediately turned the car off. Waited again and turned it on same noise.. the only thing I found was a cover under the car towards the front was really loose. ( I haven't hit bottom or anything while driving) but I did have the lighted door sills just installed the other day. But it never made that noise..
btw i have 1100 miles on it..I looked under it and is the black dust protector thing supposed to be loose like if I push on it I can make it rattle..

I have bought this car in 2006 and had a trouble free experience so far. My car had roughly 170000 Km on it. This very first generation Prius from Japan and all the instruction is in Japanese. Engine: 1NZ-FXE
Main Problem: At times when the turtle sign comes, the engines makes a lot of noise. It feels like the engine is overworking. I also hear some air suction kind of sound from the back of the car (I believe it is to do with the main battery). The car will not accelerate. I need to go to the road side and then turn off the car. Wait for a little while (may be 5 minutes). Turn the engine on and then drive again.
Other problem:
1. Red Triangle is always on (see the pic)
2. Dash Board screen is always and now completely white so I cannot see any error message (see the pic)

My 2005 with 160k miles has engine noise when cold.
I talked to a couple specialists who said it could be valve noise another said valve noise would not abate when the engine warmed up. He suspected piston slap. A valve adjustment is pricey and the local independents are afraid to touch it given the complexity and needed shim packs. If it is piston slap I would be disappointed after spending a pile of dough to still have the same noise.
Have I missed a possible cause?

Twice during the 6 months that we have owned our 2010 Prius, a loud clattering noise from under the hood occurred upon startup. After shutting it down and restarting, all was normal. It sounded like an engine that was getting ready to throw a connecting rod. The dealer could find nothing wrong and when I contacted Toyota's hot line, they were clueless as well. One service writer suggested the ABS as the source, but I've owned 5 other cars with ABS and never heard anything like it.

Just purchased a used 2008 prius with 80,000 miles on it. Braking system makes slight grinding noises when getting below around 10mph. I know the brakes are different, so I'm not sure if this is normal or if it means my brake pads need replacing? Car didn't come with an owners manual .

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.

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 have an 04 F150 Lariat with the 5.4. I get alot of noise out of the top of the motor. I hear lots of stories of sludge issues, is that the problem or do I need to have the motor gone through? the knock is not horrible but when the motor is warm the noise is pretty apparent!

I have a 2007 F-150 4x4 5.4L. I recently had a problem with my engine. It had the knocking noise thats known for the 5.4. My issue is i replaced the engine (it had 275,000 miles and was a work truck before i bought it) As well as all the timing components including the hydraulic tensioners, new phasers, new guides, new solenoid, and a new camshaft positioning sensor and it still isnt fixed.

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.

My car is making this noise. Its only at idle. Doesn't affect fuel economy, just alarming.
