How do i fix the whining noise my 2009 kia sorento makes


may be your power steering pump whining. Check fluid first, then if it's up, start the car up and have someone turn the wheel back and forth a few times. Listen to see if there is more or less noise when this happens. Does the noise go away after it warms up?

The most common source of the whine is the power steering pump is low on fluid or the pump is defective. Check the owner's manual for instructions on how to check the fluid in the pumps reservoir.

Power steering makes high whining noise I had the fluid changed and it did not help the situation. what is next


Change the power steering pump if it bothers you a lot. Otherwise, if power steering performance is ok, and you only notice a whining noise, I wouldn't worry about it too much.

2006 Buick Lacrosse with 63,000 miles. Whining noise expecially when first driving car. Especially when turning corners but also on the straight. Usually gets better when driven 5 miles or so.


Its probably the power steerinng pump. they do this sometimes when they are cold. has to work a little harder. this is normal. you might check the fliud just to make sure it is full.

Whining when i press gas


normally, the only part of your automatic transmission that will make a whining noise is the pump. it usually whines when iether the fluid is low or more commonly when the transmission oil filter is getting plugged up.

the power steering pump will also make a whining noise too.

turn the wheel all the way to the right and hold steady pressure against the stop. this puts maximum force on the power steering pump and, if the power steering pump is the one making the whine, it will change the sound of it. (usually louder).

if the trans pump is making the whine noise, it should sound different in neutral compared to drive. this test will really only work if it make the noise without the vehicle moving. if it wont do it at idle hold the rpms at 2000 or so.

if you decide the noise is coming from the transmission, and the transmission filter has not been replaced (assuming you installed a used transmission), replace the filter by removing the oil pan.



oh and also, if it is the power steering pump you should be able to make it make the whining noise while the vehicle is stationary. if it wont make noise unless its moving its not the power steering pump.

Sounds like a combination of a power steering pump (whine) AND the CV axle (loud clunk noise). Check the fluid level in the power steering pump. The pump is located on the passenger's side towards the firewall. Kind of hard to get at but unscrew the cover and there is a small/short dipstick there. See what it reads. Add Power Steering fluid (NOT transmission fluid, as needed. Don't overfill)
I'd get the "thumping noise" taken care of IMMEDIATELY. Could be a serious problem. Qualified front end shop should be able to diagnose and give you an estimate of cost. Last time I had one done it was about $300 parts and labor...

Whine usually occurs on tight turns maximising pump output and/or pump may be worn and needs replacement. Leakage can be from pump reservor,connection, or power rack and pinion steering assy. Spray off any area with a sign of fluid with a brake clean or carb. cleaner and look for signs of leakage.

My 2005 Buick LaCrosse makes a whiny noise. It is worse when going around corners. I notice when I take my foot off the gas the noise lessons significantly.


I am guessing the steering rack is starting to go bad. That is quite expensive to fix. The whining noise is the rack sucking air due to the steering fluid has leaked out. You can check your power steering fluid level and add some with stop leak to see if that helps. The filler cap is at the rear of the engine on the passenger side and is quite hard to get to. Be sure to not reach down to remove the cap unless the engine is cool. There is a high risk of burning yourself on the exhaust manifold.
