NHTSA Complaint #10854957 — 2010 GMC ACADIA

ON 9 APR 2016 ON THE WAY TO A CHURCH FUNCTION, OUR 2010 ACADIA TOLD US IT WAS REDUCING ENGINE POWER AND STARTED MISSING AND SMOKING A LITTLE. THANKFULLY WE WERE JUST BLOCKS FROM THE HOUSE, SO WE TURNED AROUND AND LIMPED IT HOME. LATER I MOVED IT FROM THE DRIVEWAY TO THE STREET. THIS TIME, WHILE STILL MISSING, THE VEHICLE PUT OUT A DENSE FOG OF WHITE SMOKE THAT SMELLED OF GASOLINE. THANKFULLY NO ONE LITE A MATCH. I USED MY OBD II CODE READER TO GET FAILURE CODES P0087 AND P0089 INDICATING LOW FUEL RAIL PRESSURE AND INJECTOR ISSUES. SUBSEQUENT RESEARCH ON-LINE LED ME TO TSB PIP4924D (NHTSA# 100419330). I NOW AM OF THE OPINION THAT THE ISSUE IS LIKELY A FUEL INJECTOR THAT IS STUCK OPEN LIKELY DUE TO A FUEL INJECTOR CONTROL LINE THAT IS SHORTING TO GROUND DUE TO BAD MANUFACTURER DESIGN OR IMPROPER MAINTENANCE BY DEALERS FIXING OTHER ISSUES. I VIEW THIS ISSUE AS A HUGE SAFETY PROBLEM. I CAN THINK OF ALL SORTS OF SCENARIOS WHERE THIS COULD CAUSE DANGER TO THE VEHICLE DRIVER AND PASSENGERS. A LITTLE ABOUT ME ... I'VE BEEN WORKING ON CARS FOR THE LAST 48 YEARS AND HOLD A BS IN ELECTRICAL ENGINEERING. ANYONE IS WELCOME TO CONTACT ME AT [XXX]. (UNRELATED ... I WAS ALSO DISAPPOINTED TO LEARN FROM ONE DEALER WHEN FIXING AN A/C ISSUE THAT MY BRAKE BOOSTER DRUM WAS CONTAMINATED WITH BRAKE FLUID DUE TO A BAD SEAL I GUESS. THAT FIX WAS COSTLY AND LIKELY SHOULD HAVE BEEN ON THE MANUFACTURER ALSO). INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR
