NHTSA Complaint #11073408 — 2012 GMC TERRAIN

THE CHECK ENGINE LIGHTS CONTINUALLY COMES ONE AND OFF. AT FIRST, WHEN MY HUSBAND TURNED ON THE TRUCK AND SAW THE CHECK ENGINE LIGHT WE TOOK IT IN AND THE ERROR WAS FOR 1 COIL PACK. IT WAS FINE FOR A MONTH, THEN AFTER STARTING THE TRUCK AGAIN THE CHECK ENGINE LIGHT CAME ON, AND WE REPLACED ALL OF THE COIL PACKS. NOW WHEN WE START THE TRUCK, THE CHECK ENGINE LIGHT MAY BE ON OR OFF. AT LEAST ONCE A WEEK, WHEN WE START THE TRUCK THE CHECK ENGINE LIGHT WILL BE ON. THIS ISSUE HAS BEEN REOCCURRING AND HAS BEEN GOING ON FOR CLOSE TO A YEAR. THE LAST 5 OR 6 TIMES WE HAD IT PUT ON THE MACHINE THERE HAVE BEEN NO ERRORS FOUND AND OUR MECHANIC'S BAFFLED. ESPECIALLY SINCE THE TRUCK MAY STUTTER OR BECOME SLUGGISH OR SHUT OFF LIKE BEFORE WHENEVER THE CHECK ENGINE LIGHT COMES BACK ON. IF SOMETHING IS WRONG WITH OUR VEHICLE BUT NO ERRORS ARE FOUND WE HAVE NO CLUE IF THERE IS TRULY SOMETHING OCCURRING AND IF IT'S CAUSING SERIOUS DAMAGE AND HARM TO OUR FAMILY. OUR VEHICLE WAS MANUFACTURED IN CANADA AND WE AREN'T SURE IF THERE COULD BE ISSUES BEING REPORTED IN CANADA THAT WE DON'T KNOW ABOUT. IN ADDITION, THERE ARE RECALLS THAT WE WEREN'T NOTIFIED OF BUT NOTHING PERTAINING TO THIS ISSUE.
