“The contact owns a 2012 Mini Cooper S. The contact stated that while driving, the vehicle failed to accelerate above 40 MPH, with the check engine warning light illuminated. The vehicle was taken to a dealer and the contact was informed that the fuel pump was defective, and the fuel pump was replaced. The contact stated that approximately a year later the failure recurred, and the vehicle was taken back to the dealer and was diagnosed and determined that the fuel pump had failed again and needed to be replaced. The fuel pump was replaced under warranty; however, the failure recently returned a third time. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 87,000.”

“I LOVE MY MINI COOPER S. BUT THERE IS A ISSUE. TODAY I STARTED UP THE CAR AND IT STARTS SMOKING. TWICE THIS HAS HAPPENED IN TWO WEEKS. WHEN I BOUGHT IT 2 YEARS AGO I NOTICED ON THE INSIDE OF MY HOOD OF THE CAR IT'S A BLACK BURNT MARK. THE DEALERSHIP SAID THE PROBLEM HAD BEEN FIXED. LAST WEEK I TOOK IT TO A OIL SHOP AND THEY SAID MY TURBO IS BURNING MY CAR AND WOULD CATCH FIRE SOON. I'M IN THE PROCESS OF GETTING A NEW TURBO BUT THIS IS A BIG PROBLEM CAUSE NOW IT'S SMOKING ONLY WHEN IN IDLE OR STARTED UP.BUT THE HOOD IS SUPER HOT AFTER A SHORT DRIVE. I HOPE YOUR CREW CAN LOOK INTO THIS PART AND SAVE SOMEONE THE TERROR OF A CAR ON FIRE. THANK YOU FOR YOUR TIME.”
