NHTSA Complaint #11403668 — 2014 GMC TERRAIN

EARLIER THIS MONTH WHILE DRIVING, OUR GMC TERRAIN BEGAN SHUDDERING WHILE IN LINE AT A DRIVE-THROUGH. A FEW DAYS LATER WHILE DRIVING, IT DIED AT A STOPLIGHT, AND WHEN RESTARTED, IMMEDIATELY DISPLAYED A WARNING THAT THERE WAS REDUCED POWER DUE TO AN OIL ISSUE. WE WERE NOT DUE FOR AN OIL CHANGE. WE HAD THE VEHICLE TOWED TO A BODY SHOP WHO INFORMED US THAT IT WAS LEAKING OIL DRASTICALLY AND HAD A LEAK IN THE REAR MAIN SEAL. WE WERE TOLD IT WAS DUE TO THE COLD WEATHER AND THAT WE WERE THE THIRD GMC TERRAIN HE HAD SEEN IN 24 HOURS WITH THE SAME ISSUE. WE HAD TO TAKE IT TO A LARGER SHOP FOR THE REPAIR WORK, WHICH TOTALLED $2,407.33 TO REPAIR. THE SHOP SAID THE PCV SYSTEM FROZE AND CAUSED THE REAR MAIN SEAL TO BLOW OUT. THEY ALSO TOLD US THERE WERE MULTIPLE OTHER GMC TERRAINS WITH THE SAME ISSUE. I LATER LEARNED THAT GMC HAD TO ISSUE A SPECIAL COVERAGE ADJUSTMENT FOR THE EXACT SAME ISSUE FOR TERRAINS FROM 2010-2013. THIS WAS THE EXACT SAME ISSUE. THE SPECIAL COVERAGE NOTES THAT "GMC TERRAIN VEHICLE MAY EXPERIENCE A FROZEN PCV SYSTEM DURING COLD WEATHER OPERATION. THIS MAY INCREASE CRANKCASE PRESSURE LEADING TO A REAR SEAL OIL LEAK." THE PART NUMBER THEY REQUIRED TO BE REPLACED WAS THE SAME PART NUMBER WE HAD REPLACED.
