NHTSA Complaint #10502192 — 2009 GMC ACADIA

DRIVING ON SR AT APPROX. 65MPH WHEN CHECK ENGINE LIGHT COMES ON AND "ENGINE POWER REDUCED" IS DISPLAYED. CAR SLOWS DRAMATICALLY AND EVENTUALLY COMES TO A STOP. POWER STEERING IS ALSO LOST CONCURRENTLY. AFTER SWERVING INTO OPPOSITE LANE, I MANAGED TO GET CAR OFF TO THE SIDE OF ROAD. CAR WAS TOWED TO DEALERSHIP (COURTESY GM ROADSIDE ASSISTANCE). FUEL PRESSURE SENSOR WAS REPLACED AFTER FINDING THE SENSOR INTERMITTENTLY SHORTING AND CAUSING THE LOW PRESSURE CONDITION. THE POWER STEERING ASSEMBLY WAS ALSO LEAKING. THE STEERING GEAR WAS REPLACED AND FLUSHED. EXACTLY ONE WEEK LATER WHILE DRIVING ON THE SAME SR AT APPROX. 55MPH, THE CHECK ENGINE LIGHT CAME ON AND "ENGINE POWER REDUCED" IS DISPLAYED. CAR SLOWS DRAMATICALLY AND COMES TO A STOP. HOWEVER, THIS TIME I WAS ABLE TO STEER CAR OFF THE SIDE OF THE ROAD WITH NO PROBLEM. HEAVY SMOKE WAS ALSO COMING FROM THE EXHAUST AND THE CAR SMELLED UNUSUAL ON THE INTERIOR. AFTER WAITING 3 HOURS FOR A TOW (GM ROADSIDE ASSISTANCE), THE CAR WAS TOWED TO THE DEALERSHIP. TWO FUEL INJECTORS WERE FOUND LEAKING (# 1 AND 3) AND WERE REPLACED. FUEL INJECTORS 2, 4, 5, AND 6 WERE REBUILT. THIS SAME VEHICLE HAD TWO FUEL INJECTORS (#3 AND 5) REPLACED IN AUGUST 2011 WHEN THIS SAME CHAIN OF EVENTS OCCURRED (PREVIOUSLY REPORTED). I AM CONCERNED AS TO WHY FUEL INJECTORS IN THIS VEHICLE CONTINUE TO FAIL CAUSING THE ENGINE TO FLOOD WITH FUEL. THE SAFETY CONCERN IS THE VEHICLE WILL DECELERATE AND STOP WITH NO WARNING WHICH COULD CAUSE A FATALITY IF I WERE ON A INTERSTATE WITH LITTLE TO NO SHOULDER. *TR
