I bought this car 2 weeks ago from a certified buick dealership. When I test drove the car I felt a small click in the steering wheel. I took it in to have it looked at and they told me nothing was wrong with it. I continued to drive it, and it got continuously worse. it would clunk while turning left and right, and you would feel it in the steering wheel, gas pedal, and brake pedal. I took it in a second time as it had gotten worse, and they replaced a wheel bearing on the passenger side. I drove it for 2 minutes then felt that the clunk had gotten even worse and felt like I was going to lose control of the steering. I brought it in a third time and they had told me that the rack and pinion had been extremely worn and was in desperate need of changing, and had loosened up my newly put on wheel bearing. Not only was this not safe to drive, it was also a hassle to find what was actually wrong with my vehicle. luckily it was covered under the Lemon Law and was free of charge.
