   Despite a recall on the fuel pump, there continues to be a problem but instead of the “back” fuel pump that was fixed, the “front” fuel pump seems to be having the same issue. When taken to the dealer, the code P0087- fuel rail/system pressure too low shows up. This is causing car to stall, unable to pick up speed or simply pick up too much speed when attempting to accelerate. It’s a safety hazard for a car less than 6 years old.
