Accent RB (2012+) :: Knocking Metal Rattling Sound When Accelerate Up A Hill Or Slight Incline

Since 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.

Camry :: Knocking Sound Occurs As Accelerate

I have a 2007 XLE-V6, bought new 10/2006, 39,500mi., and recently I had the issue of the bursting oil line that others have been having. Prior to that happening, I have been hearing a noise from the engine since the beginning of December. The noise is a ticking sound/knocking sound that occurs as I accelerate in 1,2, and 3rd gear on cold starts. This noise persists up until the time the engine reaches its ideal operating temperature, and then it just goes away.

The engine "expert" at my local dealership drove in it with me, and it only happens when the vehicle is in drive, not when idling or in reverse, so it has to be in the drivetrain somewhere. He said it shouldn't be a problem, since it does go away, but it's infuriating to hear it every morning and afternoon when I start my car.

Prius (Gen 3) :: Knocking Or Rattling Sound Comes From Underneath The Hood When Accelerate

I told them that my car sometimes when I accelerate a knocking or rattling sound comes from underneath the hood. I asked them to check it. I told him it sounded exactly like an older car I had many years ago which was the result of bad gas or too low octane.

With my older car I added higher octane gas (89) and the sound went away. I had a 2011 Prius before and never had this problem and I get gas at the same gas station for years.

So the mechanic test drove my car and said they couldn't find anything wrong with it. So I'm stuck with the annoying rattling/knocking noise when I accelerate (which happens about half the time), but now I'm experiencing another problem.

A couple days later I drove to get dinner. One way it is about 7 miles. Almost the whole way the ICE would not turn off. I would be at stop light, wouldn't turn off. I pulse and glided, when I glided the ICE remained on. Take my foot off the gas at slow speeds, ICE still on.

Finally towards the last 1 or 2 miles it started going into EV when i let the foot off the gas. On the way back it ran normal. It's been close to a week now since I brought it in for service and I only had trouble one other time.

Elantra GD (2013+) :: Rolling Object Noise When Reach Incline / Accelerate Or Turn The Car Occasionally

2014 GT ... I'm hearing some type of noise whenever I reach an incline, accelerate or turn the car occasionally. To get a mental picture, I would imagine it sounding like a loose screw rolling to and fro inside the rear drivers side door or backseat. I've looked inside the car and don't see anything.

Ford - Escort :: 1999 - Loud Knocking Sound When Decelerated Down

So my fiance and I just purchased a 1999 Ford Escort SE (4 door). Drove it home, seemed fine. Was told it just needed some TLC and would be good to go. I don't know too much about cars (Besides the basics and what certain things could mean). So, got it home, was checking it out. Revved the engine, and when it decelerated down there was a loud knock that sounds to be coming from underneath the car, I looked underneath and all that I can see which it could be (from the general location of the noise) is the engine or the pipes. So, is this a rod issue? Could it be a loose flywheel? I'm hoping we did not just buy a car to have to go scrap it to gain back some of our losses. Being as times are tough and money is tight.

Ford Super Duty (1999-2016) :: 2008 - Knocking Sound Goes Away If Tap The Accelerator

I have had this truck for several years. I have only had a few issues. I've heard of engine noise issues but I have never had any until now. My 5.4 is making a knocking sound that just started. It goes away if I tap the accelerator. It has over 200,000 miles on it. I change the oil every 3000-4000 miles. No additives and always conventional 5-20. Is this a serious issue? I've seen people talk about using thicker oil but I'm very hesitant.

Ford Super Duty (1999-2016) :: 2002 Excursion - Knocking Sound When Turning

2002 Excursion 4x4 7.3. I've read about this on here before but I've forgotten what the problem is. When the wheels are turned and the vehicle is going forward at some speed, there is a knocking sound, like a ba-doomp ba-doomp ba-doomp. Does it in both directions, sounds like its in the front hub area. I don't have the time to fix it myself, how much should I expect to pay a dealer and/or independent shop to do it?

Ford - Ranger :: 2001 - Knocking And Smoking When Accelerate Uphill

About 3 weeks after an oil change, my 01 Ford Ranger started knocking and smoking when I accelerated up hills. I checked the oil levels to find that it was completely empty. Refilled the oil, but the problem persisted. Tried gas additive--nothing. Finally limped into the Ford dealership where they kept my car for 6 weeks trying to figure out what the problem was. After new plugs, wires, MAF sensor, coil, and PCM the problem seemed to be fixed...mostly. Knocking and smoking eventually stopped until I checked the oil levels again and it was empty. Added oil which started the symptoms all over again. Mechanic ruled out blown gasket. Claims knocking and smoking are unrelated (even though they happen at the same time 100% of the time). Smoke is white. Knocking (at its worst) sounds like a bolt rattling around in engine. Car does not lose power, and when I gun the engine it seems to go away. Only happens going up hills (of which Tennessee has plenty of).

Ford Super Duty (1999-2016) :: 2011 F250 - Knocking Sound From Rear Passenger Side Cab Corner

Just became the proud owner of a used 2011 F-250 Supercab, 6.2L. Overall the truck is great but it does have a-few things that need fixing, the most annoying of which is a knocking sound from the rear passenger side cab corner. Sounds like the exhaust vibrating and smacking up against the floorboard but that's not it. Everything seems tight, even the front suspension.

The only thing I can see that may be the cause is the rear passenger cab mount seems worn. I can rotate the bottom rubber portion without too much effort and when I feel for the top rubber portion all I feel is the metal cup on the top, like the rubber has collapsed and the metal cup is sitting directly on the frame mount.

So... how many cab mounts there are for the Supercab? I think there are two on each side and two in the front. All of the information & videos I've seen describe the locations for the crew cab. Also, is it possible to replace the cab mounts and not have to mess with the ones in the front? I hear those are the real buggers.

Ford Super Duty (1999-2016) :: 2015 F250 - Cold Tranny Noise / High Rev Sound When Accelerate

Just bought my first Ford. Its a 2015 F250 Platinum. Im at 1400 miles and Im becoming concerned because when I start the truck for the first time in the day, no matter how long I let it sit and warm up I am noticing that on the first couple of miles of driving I hear a high revving sound as I accelerate and it seems to quick shift during those first few miles.

As I continue to drive the high rev sound just fades away and all engine sounds and shifting are as normal as can be and will remain that way until the truck has been sitting for an extended period of time and is cold. I thought it had something to do with tranny temp but this morning I let the tranny warm up to about 115 deg in neutral before taking off but still had the high rev for the first few miles. I have never owned a ford nor have I ever owned a heavy duty truck, hoping this is normal.

Golf IV / Jetta IV :: 1999 - Knocking Sound At Idle

1999.5 gls vr6 ... 113k on the clock

Timing chain hasn't been changed yet .. Has new spark plugs & wires ..

Water pump was replaced & pulleys look fine ..

No CEL .. Yes there's oil in it.

I get a knocking sound at idle and it has absolutely no rhyme or rhythm which makes me think it's not a valve or rod(wouldn't that make a constant noise?). The sound comes from the passenger side floor board. Only happens at idle, and if you rev the engine, it will go away. Even if you don't rev the engine some times it goes away then comes back. Sometimes I hear it when i pull up to a red light real loud & most of the time the engine purrs like a kitten. I even sat in the car and told my dad when it was making the knocking/ticking noise and he went all over the top and bottom end with a mechanical stethoscope & heard absolutely nothing. Am I missing something obvious?

Mazda :: 2008 - Grinding Sound On Slow Right Turn On A Slight Downward Incline

Our 2008 Mazda CX 9 has been making a grinding sound and also the ABS light comes on when we make a right turn on a slight decline after having come to a stop. We have reported to Mazda multiple times but they always say they can't replicate the problem and can't find anything. I am concerned that something in the car is becoming more and more damaged because there is no way something grinding like that can be good for the car and I am frustrated that it's never been diagnosed especially now that it's out of warranty although I established a record of the issue long before the warranty period expired.

Ford 6.7L Power Stroke Diesel :: 2015 - Shaking Under Slight Load Due To A Small Incline And Loud Diesel Sound

So I have just over 14k on my 2015....... I love the truck but have had a few small issues. I had a water leak coming in from the roof that would leak through the grab handle. Nothing major dealer replaced one clearance light seal and they said the windshield needs to be re sealed.

Then I had a god awful irritating squeak in the dash..... It only does it late In the day when it's been hot. The dealer said it was a loose air bag. I have had the truck back a week and it's doing it again.

Those are little issues that will get resolved...... I hate having problems with a brand new vehicle but I understand it happens and that's what warranty is for.

I also reported a bad shake to the dealer...... The truck will shake very violently and have a very loud "diesel" sound. It's very specific at when it occurs. It has only done 4 times in the past 6 weeks including today. The odd thing is the 4 times it has done it has been the same time of day in the exact same spot on the exact same road!!!!

Basically I leave my office sit in some traffic and by the time I get to the parkway it has been35 minutes or so. Only happens in 6th at 60 which is roughly 1,400rpm a slight load due to a small incline and it shakes real bad! The typical "diesel" sound you get when under a load is very pronounced almost to a knock. It will continue to do this as you slowly increase throttle until it down shifts and then goes away. I also caught it doing it and I manually shifted to 5th and it went away.

Because of the rpm at which it happens with slight load only doing it in 6th I lean to a Trans issue and more so a converter problem. It feels like converter shutter. I just don't understand the engine sound.

I gave very descriptive info to the dealer..... Several techs drove it and could not duplicate. I just picked the truck back up last Thursday and the dash squeak is back and the shake happened yesterday and again today. So I am a bit irritated to say the least.

I really hate the fact that I know there is a problem but I also understand if a tech can't duplicate it he can't diagnose it. However today I did get a video of it with my phone so they will know I'm not making this crap up!

Ford Super Duty (1999-2016) :: Power Loss Every Time On Slightest Incline On The Road

I have a 2009 f250 with 70,000 miles on it and for the last 6 months I have been experiencing some power loss. It happens every time there is the slightest incline on the road, it has to down shift to 3rd gear just to maintain that speed. If I don't push on the pedal until it down shifts to 3rd I slow down to 40mph no matter what the speed was before I hit the incline/hill. I also went from 14 mpg to 10.5mpg. I have heard so many theories and am curious if the fact I upgraded to 35 inch tires and never updated the trucks computer.

Ford Super Duty (1999-2016) :: F250 Transmission Noise When Towing On Incline From A Complete Stop

2016 F250 6.7L 4x4

I getting some tranny noise when towing on incline from a complete stop. When I slowly press the gas pedal I hear grinding noise. If i press the gas more my truck starts to move and the noise goes away. It doesnt happen all the time. This started right after my 1000 miles recommended break in before towing per ford manual.

My truck now has 2800 miles and the grinding noise occurs intermediately regular driving. Mostly on steep incline or decline. I haven't taken it to the dealer yet because I cant recreate the issue all the time.

GTI 337/20th Anniversary :: Knocking Noise When Accelerate / Turn

This started recently and it's definitely out of the norm... When I activate my signal and it switches off, i still hear the ticking but no lights are flashing. it'll go on for about a few sec then shut off, sometimes comes on even when i didn't activate my blinkers. Also when i start my car i feel a vibration from under my feet. Sounds like a knocking noise when i accelerate/turn. But then goes away after about 20 seconds of driving.

Sonata I45 (YF - 2011+) :: Knocking / Shudder While Accelerate From Cruising?

I just had my 15000 check-up for Sonata 2011 a week ago, everything went fine. The issue I am currently having is that I notice that when I drive on the freeway, after cruising for a distance and then stepping on accelerator to speed up, there is occasionally a knocking or shudder that occurs initially and then goes away. This seems to be reproducible if I accelerate, then let the car cruise, then accelerate again. But it does not happen every single time. I haven't noticed it too much on city streets.

My question is what may be causing it. If I were to take it back to the dealer, how much will I be charged for the inspection and if they were to find nothing wrong. Additionally, should I take it to the same dealer (which is about 20mi away), or a closer one?
