I just got my 2007 Lincoln MKX AWD. I love the car but it has a funny grinding noise when it reaches about 40mph. Its always at that speed. If you drive in town below that or accelerate quickly on the highway it doesn't do it. Only when average driving at 40mph. Also sometimes the left front wheel makes a noise and the traction Control light comes on. If i turn off the TCS no noise in the wheel but at times the tranny noise is still present. It doesn't feel like a slip so much as it does a grinding or harsh noise. Its hard to describe. Also when I turn hard left from the stopped position it sometimes, usually after being parked for a while, it has a hesitation for a second almost like it would if it lost power or like you pinched the fuel line and then released it. I know this sounds weird but has anyone had these problems.
