Infiniti - I35 :: Rattles / Grinding Sound When Car Is In Motion
Sep 6, 2011
I have an Infiniti i35 with about 150,000 miles that has a grinding sound that the car makes when the car is in motion. If I come to a stop, it goes away. When I start to move, the sound comes back very slowly and increases with speed. The noise doesn't go up but the grinding just goes faster. On the interstate, the steering wheel shakes a little and I can feel the gas pedal shaking too. What could this be?

It was having trouble turning over for a few weeks, getting progressively worse, but we just didn't have time to look it over. Well, it finally died--now if I turn the key a couple times we got a grinding noise but mostly just nothing at all. The lights, radio, etc all turn on though so we were sure it wasn't the battery. Thinking it was the starter, we pulled that out and took it down to Advanced Auto Parts, but they ran a test on it and said it was still good. So we put that back in the car and brought them the battery instead--they tested it and said it was charging and holding voltage but not amperage, and that, that would mean the lights and things could come on but it wouldn't have enough kick to actually start the car.
So, we bought a new battery, went home, and popped it in. Still, nothing. My friend says it's not the alternator because with a fully charged battery the car would start even if the alternator wasn't right (and would just die in a couple days, at which point you'd know you needed to replace the alternator) and my car's still not starting. The last thing we tried before we gave up for the moment last night was checking fuses in the driver's side of the car and also under the hood, the handful we thought could be related to the starter, alternator, and/or battery, but they all looked good.
The only other thing I read about online with Infinitis was that if the security system was activated it wouldn't start, however, while I noticed the light for it is flashing which I'm not sure if that was normal before or not, I THINK if it is activated it would be solid red, and at any rate, I tried what I read online to unlock it (put key forward for 5 seconds, then off, repeat 2 more times, then try to start) and that didn't do anything either.

I hear a grinding noise from tire area when in motion and when stopping and happens only intermittently. I have taken my 06 chevy uplander to 2 auto repair shops and to a chevy dealership repair shop now and all three say they can't find anything wrong with it. shortly after, the noise happened again but now when it occurs the display screen reads... Service ABS system and service Traction system... when i turn the engine off and back on again the warning is no longer there unless the noise occurs then will read both again.

Just new today a low grumble when in motion. Not the engine, all gauges check. This sound, it's constant unless I am at a complete stop, a lower sound than the engine running. There has been a putter sound for a while now, was told that was an exhaust leak. That sound I thought sounded like the bolts on the front fan hitting something, cuz that happened before, but so mechanic said it was an exhaust leak. That a very faint putter sound. So what have I got left? Something front end, I have a tiny clunk when breaking and taking off. It doesn't seem to be related to the usual stuff I've already had happen. Breaks are fine, tires wearing evenly, engine doesn't skip a beat, temp good, isn't the sound of low steering fluid cuz I know that one.
Could where ever an exhaust leak be finally break loose? I know diesel mechanics but who looks at the wheels and shocks and stuff? Just sounds like something in addition to the engine, not tire on pavement hum but something lower. Sort of surrounds you, windows up it is very faint. Doesn't affect anything either, that I can tell. Muffler? I do have a vibration noise on and off with the muffler. The best I can describe it is a low constant noise while I'm driving and it's there going slow and fast. More audible with the windows open. All I know is I don't wanna die in that truck. Been under it before and other than old leak stains, all I've ever seen is dirt in my eye. What kinda shop does shocks and wheel stuff? What can an exhaust leak do to me? Not even a vibration to go with this noise. I just don't know, this is new.

I'm hearing a disconcerting sound coming from my car as of late. It's a rattling sound, almost as if someone were shaking a can of spray paint at the same frequency as the engine. It doesn't strike me as being a heat shield, it's a heavier rattling, not really a buzz.
The sound usually occurs when I am above 2000 RPM, however, it does not match an RPM range or the car's speed—it seems more closely associated with the position of the gas pedal—about halfway to 3/4. It does not make the sound unless the car is in gear and moving.
On cold starts, the engine fires and runs, but then takes up to 30-40 seconds to really get going at a normal RPM. Efforts to coax it with the gas pedal are delayed by a second or two before they kick in...
The car is a 2001 model, and has 44,000 miles.

My wife's 2013 elantra is making s low pitched whistling sound when its in motion. Does it whether I'm coasting or accelerating. Kind of alarming considering the car is about 1 year old with 12k miles. Taking it to the dealer for a tire rotation and a oil change next week, I'll have them check it out then.

My 2012 Accent Blue is making a low pitched whistling sound when its in motion. I have an annoying problem with my car. While I'm driving the car whenever I pass 90 km/h a whistling noise are started in front of my car. Hyundai Service nor Hyundai Customer service come up with a solution. They say just go an another service an check it. I uploaded 2 videos :

I have a 2004 Saturn LW with 6 cylinders. For the past few months, but only about one or twice per month, my car has been clunking jerkily when changing gears. There is no pattern, except that it happens at slower speeds, say mostly under 40 MPH both forward and in reverse, sometimes when I put the car into gear and sometimes when it changes automatically. Yes, you have guessed it, whenever I take it in, it acts just fine, and no one can get it to duplicate the bahavior.
Oh, the dashboard the the light indicating necessary service comes on whenever the gears clunk and the car jerks, but when it behaves, no indicator light comes on.
I have about 114,000 miles on the car. do I just need new transmission fluid, or is my transmission getting shot? Am I stripping gears? do I really need to wait until the mechanic hears it? Everything could be utterly destroyed by then, right?

2011 infiniti. new rear rotors/pads 6k miles ago. now there is a rhythmic sound with very slow speed braking. like a bad spot on 1 rotor. you hear a grind, stop, grind, stop. its not a constant grind sound. i looked at both rear rotors thru rim slots. rotors look perfect. very smooth. i have not pulled wheels to check. i am thinking rotors making sound vs pads making sound. but why would a rotor have an odd spot or rough patch? there is no ridge at all on rotors. cant see the pads rubbing on some rust ridge? there is none....

2011 Saab 9-3 XWD, currently 9k miles. Just purchased a month ago. Was previously a dealer loaner vehicle. I have this noise coming from both sides of the rear when the car is in motion. I am unsure if it is just loud enough to sound like it is coming from both sides or if it is really coming from both sides.

It doesn't start immediately, only after the car has been driven a bit. The noise is most noticeable between 5 mph and 10 mph. It is definitely a rotational sound (I can notice fluctuations in the noise as the wheel spins). It appears to come from both sides. When the car is in the air and the wheels are spinning their is no noise (according to the shop I have been to, I have not been present when this has been done), so that would mean it only occurs when the wheels are touching the road. It does not change when the brakes are applied but goes away immediately when the car comes to a stop. It occurs no matter which gear the car is in (automatic). It even makes the sound when the car is off but rolling.
I have taken it to the dealership and several other repair shops. They all take apart the brakes and inspect the drive train, but no one can find anything out of the ordinary.

1987 model with 160k
Had the two tires changed a week ago - all was fine. Then developed this clicking sound when the car is moving forward.
After it first made this noise, it stopped on its own for three days - now hearing again. I looked under and could not see anything. CV boot seems fine and are recent too.
Every 2 yrs I have Sears service my brakes - not sure disc brake is slipped and touching something - never did that before but several years ago, tire shop adjusted saying it slipped.
I checked the lug nuts - they are tight. What is going on?

1999 CR-V with 70k miles. Just noticed a slight constant scraping sound when car is in motion. I had a friend drive the car in a tight circle around me while I stood in a parking lot and was able to isolate the sound to the front right wheel. Sounds like a caliper dragging on the brake disk. Brake pads have plenty of meat left on them. So far, these are the possible causes I can think of:
caliper piston sticking in bore
caliper not sliding freely on caliper pins
brake hose restriction not allowing piston to retract
I had never heard of a brake hose restriction not allowing a piston to retract, but I just read an online forum comment where someone was having a similar problem, and someone else said it was possible for an old brake hose to look fine on the outside but be swelled on the inside, thus restricting fluid flow. And can something like a stuck piston be remedied with grease, or does the whole caliper have to be replaced?

I drive an Infiniti i30. When I bought it, the guy who sold it to me told me that the car runs great but that I would have to turn the key kind of hard to get the car started. Over time, this problem has progressively gotten worse. There have been times where I'd be stuck in a parking lot for over an hour trying to get the car to start. When I turn the key, I can hear the starter clicking, and all of the dash lots and radio will come on but the car doesn't sound like its cranking or even trying to start. The weirdest thing is that the first time I drive my car in the morning it starts up just fine. It's once I turn the car off after driving somewhere and try to start it again that I have problems. I'll have to turn the key 100 times or more sometimes to get it to start if its not the first time of the day. What this could be?

My 2007 Prius (151,000 miles) just started making what sounds like a scraping sound when in motion. This does not happen every time I drive it. The dealership said I need to replace the brake fluid actuator pump.
He couldn't really tell me what would happen if I don't have it fixed. He said perhaps the power brakes would go out, or maybe the anti-lock brake system. Either way, I don't want to mess with possible brake failure. But the cost of this repair is so high, and my car already has 151,000 miles. I'd love to drive it to 300,000 miles if I can, but am I being realistic? I'm wondering if it's worth investing this much money in a car with so many miles.

It sounds horrible, I don't know what VW did but with these Fender speakers but they really sound horrible. Everything rattles.. Then I asked them to install the Jetta anti rattle kit and they didn't even know what I was talking about...saying they never heard of anything like that before.

My 05 Explorer has started making a like slightly jumping motion and thumping sound when I let off the gas. It seems to maybe happen when it wants to gear down but it I give it the slightest gas it quits. Do you check the ans fluid when it's hot or cold? I checked it hot and it ran out.

Ok a new rattle is going on in my 2006 Azera. Not sure where the rattle is coming from. Took it to the dealer last month for a oil change and asked them to look at the underbody to see if anything was loose. The service manager said everything looked fine. So if it isn't rattling there where else as I can tell something is loose somewhere.
I looked in the trunk yesterday and everything is sound in there didn't look at the spare so that is the next step. Doors sound solid but I hear it when driving like something is knocking lighly under the car. Thought it might be the tail pipe of something connected. I been riding my Burgman 650 most of the summer so far but when I pick up my girlfriend in the Azera I hear it from her and then from the car.

It started a couple months back, under about 20 mph I feel/hear a rubbing or grinding sound. Appears to be coming from the front end, I put I on a rack and drove it but couldn't isolate a cause. I rotated the tires, replaced the brakes to be sure there was no warping. Everything looks good, but something clearly isn't.

I have a strange grinding sound coming from under the hood, more precisely in front of the pass side, when I lift the hood, the noise is likely coming from the part that has these two caps on top. It starts right after I start the car, stops after several minutes, just for 3-4 seconds, and than again....

So... I bought Ksport Coilovers and had them installed about a month ago. Were on the car about a week and started to get creaking noises from the front. So, I contacted BSH (who sold them) who put me in contact with the Director of Operations for Ksport...
Send them to him, and he replies that he thinks my sway bar is high, and that it should be "parallel with the ground. Today when backing up (down right) I get a horrible scraping grinding sound. I stop, get out (thinking it is the fender liner) only to find no damage. So I keep checking and find a fresh scrape on the axle. I drive (gingerly) home and pull the wheels off and check everything in the front. It is all tight and nothing seems to be broken. I look at the sway bar end (which is curved).
