Prius (2010-12) :: Engine Making Pinging / Knocking Noise At Low Hybrid Battery Level
Recently 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 RepliesSonata NF (2006-10) :: 2007 - Knocking Sound From Engine
I own a 07 Hyundai Sonata Limited with 31000 miles. It is 20 degrees today. When I start the car up there is this knocking sound from the engine. Once the car warms up the knocking sound only happens when the car is in drive or reverse. When the car is in park or neutral it is fairly quiet. The sounds is still there but not as loud as in drive or reverse. I have done the routine synthetic blend oil changes between 3500-4500 miles.

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.
View 27 RepliesSonata NF (2006-10) :: Knocking Sound From The Engine / Cutting Out After Idling
I was driving this morning after doing a brake job (nothing to do with the problem, just anger coming out) made it about 10 kms and noticed when i took my foot off the accelerator, the heater fan powered down a bit, and back up when I gave it gas...noticed a knocking sound from the engine...pulled into a gas station and put it in park. After a hard time idling, it cut out. I started it again and the idle was not good at all. kept cutting out. Got it going and made it home with the same sort of power issue. Tried to start it a couple times and same issue with the idle. Sputtering quite a bit and noticed quite a bit of exhaust coming out. When I backed it out of the garage, I noticed a small puddle of oil.
View 15 RepliesPassat (B5) :: Engine Makes Knocking Sound At Idle After 30 Minutes - Code P0411
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).
Passat (B5) :: Engine Pinging Intermittently When Accelerating At Fairly Low RPM
I have a 99 1.8T Passat (with automatic) and I hear it pinging slightly here and there when it is warm outside. I use name-brand premium gas every time. The spark plugs are fairly new and the temperature gauge consistently shows that it runs at 190 degrees F. I have 103,000 miles and it runs fine otherwise. It doesn't ping all the time, but does so intermittently when accelerating at fairly low RPM. I change the oil every 4,000 miles religiously and just switched to synthetic oil. The "check engine" light is not on and it easily passed the California smog check just a month ago. What it might be? Could it just be a little carbon buildup due to age?
View 8 RepliesToyota - 4runner :: Pinging / Knocking On Hard Acceleration
I have a 98 Toyota 4Runner, which just started what I'm told is pinging or knocking on "hard accelerations", like accelerating on the merge lane when I see cars coming up behind me in the lane I want to merge into, or going uphill. i have 258,000 miles, and have the SUV serviced regularly and get things fixed when they need it. I told the dealer about it a month ago when I had regular servicing, and he did something to clean the fuel injector, and suggested I try 89 octane (he specifically recommended Sunoco), and if that worked I could try going back to 87 octane (Sunoco was his recommendation again). I did as he suggested, and the pinging/knocking seemed to get better with 89, but returned with 87. I read the Q&A on this, but still have questions. Why did this just start after 14 years? Should I do anything about, in other words is it harmful? If so, what should I do? Does the brand of gasoline have anything to do with this, or anything else for that matter? I am hoping to keep the SUV for a couple more years (300,000 miles), maybe longer.

I recently changed my oil, transmission fluid, and both coolant systems. I have a 2008 Prius, and I can hear this noise coming from the engine when I accelerate between 50-70 MPH or have the cruise control on.
I had low coolant in the ICE system earlier (didn't know there were two separate systems) and I had the red triangle light up for a moment and "Problem" appear on the LCD screen followed by an orange thermometer. I pulled over and let it cool down, and babied it home and added coolant.
Ford Ranger / B-Series :: 2003 2.3L - Pinging / Tapping Or Knocking Noise
My 2003 Ranger 2.3L When I purchased it in 2005 I never noticed this tapping noise until in 2007 when Tennessee forced 10% Ethanol added to fuel. That is when the noise started.
What this could be. I have since moved to Texas and found a station that sells Ethanol Free gas, but that does not remove the noise.
Sonata NF (2006-10) :: Knocking Sound From Motor After It Warms Up

View 6 RepliesSonata NF (2006-10) :: Knocking / Creaking Sound Only In Hot Weather
I have a 2009 Sonata Limited (4 cyl), and since the beginning of the summer, I have had a knocking/creaking type sound coming from both the front AND back of the car, which feels like is coming from underneath. I can feel it in the floor when it gets really hot, and therefore really bad. I hear it almost exclusively while accelerating or coming to a complete stop. When it gets really hot out, I can hear it very slightly while driving at slower speeds, but that's about it. Has no correlation to making turns, as would be the case with a tie rod.
I find it extremely strange that this is happening only in the heat. When it's cooler out, say below 80-85 degrees, there is no sound whatsoever. The car runs phenomenally otherwise, very quiet. Based on some stuff I've read, it seems like a suspension issue is a possibility? I live in a neighborhood with extremely poor roads, and actually live on a dirt road.
Sonata NF (2006-10) :: Slight Knocking Sound - Possible Bad Rod Bearings?
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
Sonata NF (2006-10) :: Knocking Sound On Cold Start
2005(its NF model) Sonata 2.4 petrol manual. 75000 miles. On cold start makes knocking sound( sound like Diesel). After coupe of minutes when warms up the knocking sound gone.
Also when i start driving( still on cold engine) i hear that sound only when i let go from gas pedal and only in range of 1800-1500 rpm. When i accelerate i don't hear that knocking sound.
I think is not belt tensioner because sound is much longer than couple of sec.
Passat (B5) :: 2002 - Thumping / Knocking Sound From Front End
I 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 9 RepliesPassat (B6) :: Random Loud Knocking Sound On The Front End
Experienced 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 RepliesPassat (B6) :: Knocking / Popping Sound After Installation Of Coilover
I 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.

Passat (B6) :: 2010 - Slight Knocking Sound - Is This Normal
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.
