Question about 2003 Volvo XC90

Open Question

Front end makes low-pitched humming/grinding sound when accelerating.

My 2003 Volvo XC90 vibrates and makes a low-pitched humming, and somewhat grinding, sound from the front-end undercarriage. It happens when the accelerator is pushed in slightly, such as when keeping a constant speed while going uphill. Also, when maintaining a low, set speed (below 40 mph) on flat pavement. The vibration and sound intensify when the accelerator is applied more, but stop when my foot is taken off the accelerator pedal.

SOURCE: Vibration on the floor underneath gas pedal

I would venture to say your exhaust is hitting your frame, or, you may need new motor mounts. The exhaust is what I would lean toward. If you can imagine your exhaust sitting under your vehicle, and the fact that the vehicle has a little age, the motor mounts probably give a little, causing the motor to move slightly on acceleration and deceleration, thus your exhaust is going to move, and may be vibrating on whatever its touching. Good luck.

My 2003 Altima 2.5s makes a humming type (vibration?)sound.


I have a 2003 Nissan Altima making a humming sound towards the front of the motor at idle in Park.

Not sure if alternator or compressor.

Not rattle from timing cover has to be something Nissan already denies.

1999 Ford Ranger Front right brakes are making a grinding sound and a high pitch when i turn left, Do you know what it is ?


the grinding sound and the high pitch sound may not be related.
the grinding in the brakes means it is time to replace the brake pads / shoes and either replace or repair the discs and drums.

the high pitch noise that you are hearing while turning is more likely caused by a worn belt, low power steering fluid, or a faulty power steering pump.

Although it could be indicating something more serious like hub bearings going out, your best bet is to take it to a front end shop that offers free estimates and have them diagnose it in person.

hope this helps.

When I pass 25 - 30 mph my car suddenly sounds like an airplane. It makes no sound when at a stop, only when in motion going past 30. at times it feels like it may be vibrating.


Hi, sounds like a bad wheel bearing, possible tire noise, if you can identify or narrow down which end of the car (front or rear) its coming from you can rotate your tires(front to back) and test drive and see if the sound moves to opposite end now. If not you can use a stethoscope or long screw drivers and spin each wheel by hand (vehicle not running!) and listen for a humming grinding sound while tires are off ground via a lift or jack.

2004 volvo xc90 aw drive new front brakes and rotors and now the pedal goes to the floor and it does not stop as well i have double checked my work and bleed the brakes in the order volvo says to any ideas...


This sounds to me like classic air in the lines. It is also possible that you are low on brake fluid, but having just bled the brakes this seems unlikely. I think what needs to be done is a re-bleed, ensuring the brake fluid level does not get too low in the process, and then you need to ensure that the bleed nipples and the brake lines are sealed properly. Good luck!

2004 Chrysler Crossfire 25,000 mls auto, road hum noise


MOST of the hums after a while come from the diff as the back axle does the driving and almost all its life runs the same way except when going in reverse ,is the rear diff meshing and worn on both the crownwheel and the pinion and the humming gets slightly louder the faster you go and almost goes when almost stopped and this can also be the slight vibration you get so get the diff oil drained and refilled and check if there is any metal in the oil when drained if so thats your problem But it will last for years like that..Let me know how you get on RON

2005 XC90 T6 AWD making a whirling noise upon acceleration


Add me to the list. Just got back from a Volvo dealership in Chicago and was told the 'winding' noise we're experiencing during deceleration in our 2004 XC90 is due to a failing transmission,so i would suspect the same accelerating. hope all works out for you
