I've been having problems with my right front end since I bought the car. When I cut the wheel hard to the right, it makes a loud thumping noise like something is going to pop off. It makes the most noise in a slow or parking movement. Then I take it in and they pump up the tires with air, and say there's nothing wrong with it. Then the air low light for the tires comes on. You fill it up, and then another one comes on. Then check the air bag pops ons. I've even experienced the car literally feeling like the motor idling real low to almost shut off. This has happened atleast 3 times. I was only doing about 25 miles an hour, but it was really cold outside. Everytime I have taken it for repair, they have said, we can't find anything wrong.
