After 2500 miles,first time I tried cruise control for 2 minute then my car can not go forward on the free way in the middle of the freeway I try to pull over but I couldn't slowly I pull over left line. I have 3 years baby in my Tribute I was scared. I called Mazda 1800 number the answer is they can not do anything because Saturday, and I have full coverage 50,000 miles bumper to bumper and new SUV.
