Accent RB (2012+) :: Knocking Metal Rattling Sound When Accelerate Up A Hill Or Slight Incline
Sep 19, 2013
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.

My ford windstar was making a clacking knocking sound when I had to accelerate for an incline. ( I live in the mountains) Last night on my way home from work it was clacking more often. It has also within the last couple weeks randomly acted like it was not going to start almost like it wasn't getting any gas. The not starting is almost an everytime occurrence and today it started clacking any time moving and this evening it started clacking as soon as you start it. [URL]............

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.

A strange thing happened today. I was the first car stopped at a light on a slight incline and decided I wanted to take my foot off the brake. The incline was not quite great enough to keep the car from slightly inching forward so I set the emergency brake. This light is pretty long, at least 2-3 minutes. About halfway through this wait, I started smelling a burning smell, almost like burning wires. I'm not entirely sure it was actually my car because my windows were down but the smell was quite strong inside my car and started dissipating after releasing the emergency brake and putting the tranny in neutral. So, my question is, is there anything bad about what I did? Setting the emergency brake while in drive should be no different than having the hydraulic brakes holding the car at a light, so I don't see how the tranny was being stressed or the brakes since the car wasn't moving. Nothing else was on in my car, not the vent fan nor the radio. So was this just a coincidence or was I harming something?

I have a 12 day old Hyundai Accent 2012. I got the GL automatic transmission with a 1.4L engine.
I noticed a rattling sound inside the engine bay after a week of using the new ACCENT. It rattles when the engine is at medium effort. Usually i hear this kind of rattling sound with my 20 year old Mazda, but with a 12 day old car? WHAT?!
Got it serviced with Hyundai but they think it's the unleaded gasoline that's causing it, but they don't recommend using the high octane one. Talking with the technicians there, a lot of 2012 Accent owners already came back to the shop to complain about their rattling sound in the engine bay and i was not the worse sounding one.
I will record my rattling sound tonight by placing a small microphone inside the engine bay and post it youtube.

I got my HSD HR coilovers and they went on great but its like there's a bumping or knocking sound coming from the rear that wasn't there before? They look great and got me as low as I wanted.

I have a squeaking sound that's coming out of my car when I accelerate and it has been persistent for the past few weeks. I'd like to fix it myself if possible. It seems like it's just a loose belt, but I'm not sure. If I don't have a lift, jack, or car mechanic experience is it reasonable to think that I could figure it out safely? I'm relatively good with my hands and at figuring things out. Are there any serious risks of damage to myself or the car from me tampering with the belts?

Went to dealer today for rattling noise which appeared to be coming from bottom of engine on passenger side. Dealer diagnosed bad a/c compressor and had to order. This noise has been going on for past week and noise appeared with and without a/c on and always at "idle" speed. Noise would go from barely audible to very noisy and loudest with a/c on. If I turned a/c off, noise would diminish immediately; however, still audible with a/c on. Car only has 2,950 miles and a/c works fine, other than the rattling noise at times.

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.

I have about 3,000 miles on my 2014 Camry and the tranny just doesn't "feel" right. Seems clunky and the car lurches a bit when you need to accelerate up a hill. I traded in my 2007 Camry for this car and the '07 performed far better.

I have a 2012 Toyota Camry and I noticed that when I am on a slight upward hill, my Camry will slowly roll back if I don't have my brake pedal applied. Does this happen to you and is it normal? This is my first new car and my old car which was a 94 lincoln never did this even on very steep hills.

My 2012 Plug-in spontaneously started making a metal scraping/rattling noise in the middle of a low-speed drive around the neighborhood yesterday. Seems to be coming from the left front wheel area. I've checked thoroughly under the car and in the front wheel wells for anything that could be dragging/rubbing, and I can't find a culprit there.
It occurs while coasting in EV mode, so not ICE/exhaust related. The car doesn't pull to one side or the other. Only 9K miles, so I wouldn't suspect a hub bearing or any other significant wear to be causing this.
Possible clue or red herring: the dealer replaced the the left front tire and did an alignment two days ago, and the noise occurred within 15 miles of driving after that service.

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!

Was climbing a steep hill at 35 mph just before truck down shifted to 2nd, I was hearing a pinging sound. Sounded like only I cylinder was doing so. What it could be. I am currently running a 1/4 tank of Fppf fuel injector cleaner. Is this a injector noise. No knocking just a slight pinging.

so with the weather turning cooler i have noticed a new noise. i am at 34,000 miles and run synthetic oil ever 4-5k miles.
I hear a rattling/knocking noise when you start engine, not right away, but like after 15 seconds and it lasts about 30 seconds then seems to go away and is quiet again.
Almost sounds like a lifter is tapping due to not getting oil.
I changed the accessory belts a while ago and it did not first make this noise right after but maybe a few days after which coincided going from 80 degree weather down to 40 degree weather.
Could it be an accessory belt being too tight? If so, why wouldn't it make it on startup? I can see it going away as rubber expands as the warms but I would expect it to make the noise from starting till then. Not 15 seconds into running.

When I accelerate I notice a rattling noise almost each time. Is it bad gas? I have been getting gas (90-95% of the time) at the same gas station for years, including the whole time with my 2011.
Also for the first time today i got an error message on my screen for the radio that says something to the effect that the USB has too much power consumption and will not run.
When I powered off and powered back on after lunch it started working again. I never had either problem with my 2011.

I live in the mountains an back into my driveway that is on a steep hill. My car has rolled backwards twice now with the parking break engaged. The first time it came to a halt where it flattened out. Last night I had my truck parked behind it and it rolled into our recycling and garbage bins and pinned them between the car and the truck. I have a significant dent below the window on my hatch.
Manual transmission. Parking brake engaged. Car was in neutral. I usually leave my car in first when parking on a hill. I am not sure if it slipped out of gear or I left it in neutral by accident.

Yesterday, I noticed a rattling sound coming from the entire car a 2002 subaru outback 2.5l 4 cylander (it seems a bit louder on the passenger side but it literally can be heard throughout the car). I was on the expressway and got off and stopped at a red light when the check engine light came on and started to flash and the rpm's dropped rapidly and the needle began to bounce up and down. I pulled into a gas station to check it out more and popped the hood to find that when the car is rattling it is also shaking and rocking the engine of the car from side to side slightly.
When I'm idling the rpm's drop and the car feels like it is going to stall out. Then, as I accelerate, the rpm's barely go above 2000 and jump up quickly between 3000 & 4000. It sounds like a metal on metal rattle with a very slight high pitched whistle and you can hear a fan kick on and the engine try to keep the rpm's up every couple of seconds when the car is stopped. I had the timing belts replaced 2 years ago and it sounds very similar to how it did when they needed to be changed, however, the engine never felt like it was going to stall until yesterday.
When idling the noise gets louder and when accelerating it can still be heard but barely. Also, the rattling has caused the entire car to vibrate all of the time. I noticed yesterday that the oil was low and topped it off, but I don't think that would cause such a hige issue so quickly. When I go uphill, i have a good amount of power but every 30 second or so the car shifts and the rpm's jump lurching the car forward because of the surge of power. Also, when I hit the brakes, my rpm's jump slightly to about halfway above the 1 but the engine does not 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.

I own a 2012 Sonata GLS -Automatic with about 66K on it.
So I don't know if it's the cold weather or what, but there is some light 3 second rattling going on from under the hood which has made me nervous. (seems to be coming from left side where the belts are - facing the hood- )
Two days ago, the malfunction light came on. The car stalled for a brief few seconds. Wife turns off and turns car on. She gets it moving. An hour later, I find an error read back: P0014 -Exhaust ( Camshift Position Timing - Over-Balanced (Bank 1). I took it to the mechanic, we replaced the oil and filter. Light goes away. No stalls since.
Still the rattling is there. Today as I was driving home, the car had a very slight chug, almost as if the car put on the brakes on its own, for about a split second. I was not shifting gears.
I am due for an alignment. Don't know if that has anything to do with it.

I have a 2005 hyundai accent, 62000 miles. When I accelerate there is a vibrating/rattling noise that sounds like it's in the back left side. It only happens sometimes. It happens when i accelerate slowly or up a hill, and if i press on the gas it stops. I thought it was the muffler, but I got the car inspected in May and it was fine. It's been doing it since before then. My dad said it might be a loose heat shield vibrating. It seems to be getting more frequent with humid weather. Should I be worried?
