I have a 2009 Buick Lacrosse. After a year of driving with no issues, it has a very loud whining noise every time I crank it and never stops until I turn off engine. Does it in drive and park and at all...


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.

Car will not turn over on first try


Hey Ben, the lacrosse has several modules that all need to agree in order for the vehicle to crank and run, it's not like the old days when u were actually powering up the starter by the key via the switch, but any time a issue is recorded the control module will usually store a trouble code even though you may not have any warning lights on, take it in and have it checked for any codes, oh and it will need to be a dealer, the little auto part stores can only check certain codes, the will not be able to even scan for theft style codes as you most likely have.

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.

My 1999 Buick Lesabre makes a whining and sometimes thumping noise when I make turns at low speeds. What could it be? It became worse after a slow turn from a driveway. At that time it made a very loud...


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...

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.
