I'm just starting to break in a new 2010 Passat and I hear some slight "knocking" noises at low RPMs during acceleration. It's only got 500 miles on it, so I am assuming it's just a characteristic of these engines; however, I've never owned a VW before so I don't know what is normal. this sound is typical for VW 2.0s? I think I have the PZEV version if that makes a difference.
View 1 RepliesI know all Hyundai's 1.8L Nu engines have that quiet ticking noise. But is there a slight knocking sound on the left side of the engine (around the belt area)? Could this be just the timing chain noise? It does this on idle but when on a constant speed/rpm, the engine is quiet.
View 10 RepliesI have a 2000 neon, a knocking sound has started only when I get on the gas a bit harder than normal from a dead stop. It seems to last only a few seconds knock knock really fast and then its gone, does not sound like engine knock (rocker knock or persistent knock) more like a mechanical noise. Where to start ? Front breaks were done 4months ago, new rotors / pads / and 1 caliper ...
Seems it to be worse now....now starting to lean towards broken motor mount ... how to check or where to find them. Also now starting to hear while braking.
I have a 2007 sonata 2.4L with 93k miles that has a knocking sounds coming from the bottom of the engine. It seems that it is a bad rod bearing and was caused by low oil levels. I did not know that the oil was that low (3 quarts low) It started about a week ago. I know I'm gonna have to put it on jack stands and drop the oil pan.
By the way, Here is a video I found and it sounds similar to my car. Here's the link : 2.4L Theta Engine Noise - YouTube
This is my new Prius C's engine warming up in the morning. The engine shakes once when starting up and I seems to be able to detect a slight knocking sound.
View 4 RepliesI've been noticing that my 1994 Ford Ranger 2.3L, 4 banger has a slight knocking sound. It is really faint compared to any other rod knock I have heard. An engine compression test shows mid 140's on all cylinders except one of them which is at 125. I'm guessing it isn't receiving enough oil. Can I prevent catastrophe by fixing this early on before a rebuild or replacement has to happen?
View 19 RepliesSince about 5000 km, I have had a knocking metal rattling sound happening when I accelerate up a hill or a slight incline. It has happened a few times on flat road as well just more prevalent on the uphill battles. Now I assumed it was jus something loose that was rattling since I installed a cold air intake and had installed hid lights(I thought the ballast was banging on something). I tried and tried to find the rattle but I had no success. I read up on here about other people suffering the same problem and that running higher octane gas would solve it well I tried 89 and it was still there just not as much and I recently started using 91 and its gone haven't heard it at all.
View 132 RepliesI have a 2010 SEL with auto transmission (obviously). When it changes gears both up and down shift there is a clicking noise. I don't remember hearing it before about a month ago, but that doesn't mean it wasn't there.
View 5 RepliesI got new 2010 golf almost a month ago. And I drove just over 1000k so far. Couple of days ago i noticed that sometimes (very randomly) when i stop some knocking sound starts coming from rear (i think somewhere around passenger side). As i stand at alight and the sound comes on, the sound disappears if i take my foot off the breaks and then appears again if i push the brakes. The sound usually goes away in about a minute. Again, the sound is quite random so I'm not able to reproduce it.
View 6 RepliesI have a 2015 Elantra GL. These past couple weeks I have noticed the following:
1) After a long drive, there is a sort of "knocking" sound at the back of my car. It's not too loud but still noticeable. It seems to go back and forth from left to right to left to right, etc.
2) The sound ONLY appears at low speed (under 30km/hr or 20mph) AND when the ride gets a little bumpy (i.e. when I drive over the bump to get into my driveway). It doesn't take a big bump, just a little.
3) The sound ONLY appear after a long drive. When I start driving to work starting on my local roads at low speed over some bumps, there is no sound. But once I reach my work parking lot and I'm driving slowly and there's some minor bumps, I hear the sound. After work when I'm in the same parking lot going at the same low speed over the same bumps, there is no sound. Once I reach home and driving slowly over local road and over driveway bump, the sound appears.
The car is only at 5000km right now. I haven't gotten an oil change yet or any servicing on the car whatsoever. I will be bringing my car into the dealer for it's first oil change in a couple weeks and will ask them about the sound there. To summarize, the sound only appears once I've driven it for awhile (it never happens at start of drive) and if it's going low speed and if it gets slightly bumpy.
When I start my 2012 prius the noise scared me. The motor shook an inch and a half first tow found nothing. It did it again drove it in nothing found could not duplicate. Third time towed and again nothing found. "It is safe to drive we can find nothing wrong". After asking for a manager and inquiring about lemon status I was given a car to drive. The service rep said a manifold would be in in about a month but the mechanic supervisor said there is no eta and we are working on it.
A week later they call the manifold was replaced and they finally duplicated the issue in one of the other three cars there with same complaint. I was getting 50 mpg until this started when I took it in I was getting 46mpg. Now after the first 300 miles since I got it back I'm getting 43.5mpg.
The tone of my horn changes intermittenly from normal sound to high pitch. The high pitch sounds similar to a Japanese made 4 cylinder...for lack of a better description.
View 1 RepliesI bought a used 2010 GMC Terrain with 28,000 miles on it in April of 2013. Two weeks after I purchased the car I heard a knocking sound and the check engine light came on. Took it to Dealer and they said the car is low on oil. They put in oil. Two weeks later check engine light comes back on. They put it through a test for oil consumption and that they said the car is using an excessive amount of oil. So they had to change out all of the pistons. One month later the check engine light comes back on.
Dealer calls GM and they say to reset computer....... three weeks later check engine light comes back on....... GM now says to dealer it needs a new engine computer. Not an hour after I pick the car up from it lastest stay at the dealer the light comes back on. GM doesn't know what it is. The mechanic at the dealer is awesome he did some research and thinks the problem is the gas. I now need to put in 90 or above so the engine won't knock. Not happy right now I didn't think that I would have to put in a high octane gas when I bought the car. Terrain owners do you have to put in a high octane gas?
Temp control is stuck, but when it reaches over 55 degrees or so, it goes back to normal. Have a very slight clicking sound/feel when it is normal. Toyota wants 10 hours labor up front.
View 1 RepliesI replaced the drivers side CV axle due to the fact my wife and I both heard the famous clicking sound when turning left, I inspected the CV axle and it looked to be in good shape, no tears or rips but I replaced it anyways and now I am hearing and feeling a knocking sound (seems to be coming from the inner shaft, but not positive) when I am driving. It is also vibrating the steering wheel.
View 1 RepliesI have a 2013 Elantra, owned since new... I recently started hearing a knocking sound coming from both front wheels while turning in reverse. I have yet to take my car in to have it looked at, if I can do it myself I will but I'm not sure where to start.
View 3 RepliesI just bought an '02 Passat with 42k miles on it. I didn't notice it when I test drove it but now I'm hearing a knocking/thumping sound from the front end that goes to the speed of the wheels at slow speeds (10-30mph). I can also feel it pulse when I use the brakes at slow speeds. What this might be?
View 3 RepliesExperiencing a knocking sound coming from the dash area, sounds like passenger side, when slowing down or idling. Just started about a week ago and sounds like someone knocking on wood, or a door.
View 9 RepliesExperienced a loud "knocking" sound coming from the Passat's front end? It doesn't happen very often, but when it does, it sounds like it's originating from the front axle area. I haven't pinpointed a pattern yet, but it seems to happen when there's additional weight being put on the front end--i.e. at the point of going down a hill to flat, or when initially going up a hill from flat. And no, I'm not bottoming out. Basically, the knock sound is so random/loud/alarming.
View 24 RepliesI recently installed solowerks s1 coilovers and now I get this knocking sound coming from both front wheels. This only happens while turning at low speed and stops once I get past 30mph. Also there sounds like a rattle or clanking when going over bumps in a straight line. These 2 sounds are completely different. From what I've researched, I think the problem is broken top strut mounts. I wanted some second opinions on it before I buy the strut mounts and get in there.
This video shows you the noise when I turn the wheel side to side while parked.

I took my car into the dealer to have them check out the loud knocking/pinging sound from the engine. First time, they told me that it was normal. It bugged the heck out of me so I took it in for the second time. Note: I was given a loaner to drive and it happened to be another 06 Passat 2.0T and this one sounded fine to me. The lead tech did kind of agree that it was a bit loud. So, they replaced a new fuel pump and did an oil change....?? But that of course didn't fix the issue. The noise is so loud that I can hear it inside the car w/ windows up when I'm sitting in traffic or at the light. Also at night, I can hear it when I'm standing about 15 or 20 yrds away from the front of the car.
I realize that the engines will have some sort of knocking sound (my 330i does that), but shouldn't be this loud. So, does this sound normal? BTW, the dealer told me that they contacted VW engineers and was told that it was perfectly normal. I don't really buy that!! I've only had this car for almost a month (took advantage of the CPO w/ 2.9% fin) and I don't want to have to deal with this if this seems to be an issue. I guess who does, huh?
