There is a single "thunk" noise from the front of the vehicle sometimes when I drive. It often happens after reversing to the left out of the garage and then turning right to proceed down the street. Shortly after advancing to the right there is a "thunk" noise. It also does it sometimes when just driving, though a steering wheel adjustment always preceeds it. I have taken it to the dealer and he drove it around for a few minutes. It did it once, but he missed the noise (probably because he wasn't wearing his safety belt and the ding ding safety belt noise was continually going). He told me to keep and ear out for it and bring it back if it got worse. Said he thought it was just new car noise that will work itself out. Does this sound reasonable? New car noise? I plan on bringing it back in a few days as it continues and I am concerned. Could any of those recalls explain this?
