My van has been having problems with the turbo injection pump. When I drive it starts going faster by itself and i almost get into car accidents. I had to change the pump 4 times ! and I cant get a 5th one because General motors because my van is 10 years old and unelligable It has a factory defect. I had a problem with this ever since i got it. General motors tried to keep it quiet and wont let me complain about .I have to pay $1800 every 6 months and im getting tired of it. Please help me out !
