“While driving down the turner turnpike (between tulsa and okc, around 70-75mph)the vehicle without warning has swerved left and right on three different occasions. The action felt as if the hand of god was throwing us left and then right. The car has a mind of its own. Then the last time that I drove the car it suddenly yanked me off the road without warning, literally trying to kill us. This last incident occurred when the car had around 1,750 miles on it. The thing is dangerous! I now own a car that I can't put my family in and should not be allowed on the road. …”
