Original owner of a 2007 Buick Lacrosse cxl. Power steering pump failure at around 85,000 miles. Power steering pump failed because of leaking hoses. Primary reason for leak is due to lines incorrectly crimped around the metal line that adheres to rubber hose. Lines cannot withstand pressure and start leaking intermittently until they completely fail. I have replaced power steering pump and rack and pinion due to faulty lines damaging the whole system. I have seen many instances online about people having to replace a couple months later after initial replacement. This is a manufacturers defect of power steering lines that are out on the market. Another issue is the clunking sound that is coming from the steering column.

While making a right hand turn I heard a pop noise simultaneously vehicle dipped harshly with the handling and steering control compromised. After inspection the fractured and broken sway bar was discovered. Sway bar ends cracked both sides with right side completely severed. Car was used in normal driving conditions-mechanic suggested I report this safety issue because this should not happen.
Control arm bushing failed, causing the control arm to grind into the sub frame of the car. The sub frame is aluminum and was damaged very quickly. This issue gave no indication and only became apparent under visual inspection while the car was being serviced for another complaint. The sub frame could fail completely causing steering suspension and brakes to fail.
The steering is almost impossible to turn at slow speed or idle. It has 64,000 miles on it. Please help, it's not a safe care to be driving and as many of the same problems others have with the same year and supposedly fixed by Buick in 2008 I think they need to upgrade our steering gear.
Noise like rubbing sound coming from steering column area. Steering gear was replaced once, probably two years ago and now making same sound as before. The tires have been replaced repeatedly on this vehicle and it still feels like it is hopping or walking instead of rolling. This occurs most prominently in the morning at startup and will continue up to 50 MPH and beyond. The mechanics will not recognize the problem and have not been able to get authorization from GM regional to do anything other than charge a fee for further diagnosis. This problem existed from the time the vehicle was purchased and the dealerships share information and will not independently diagnose the problem. I have requested GM and Buick to provide a mechanic that is familiar with this problem and can resolve it, but they refuse to act. …
While driving on the highway in the rain, my headlights went out. I was terrified. Turning the switch on and off would not fix the problem. I took the car to the dealership. They said they could not duplicate the problem and would not fix it. I had taken the car to the dealership shortly after purchase in 2009 and had complained of leaking seal on the top edge of the driver's side door in the rain. Water would drip all over my left arm, shoulder and arm rest. They said they could not duplicate the problem and would not fix it. Now the headlights will refuse to work on an intermittent basis. The dealership will not fix it. The dash reads headlights suggested but they will not come on. I can use the dimmer on the steering column and the bright lights will work, but driving with bright lights into oncoming traffic is dangerous. I need to have a dealer fix this problem. …
