NHTSA Complaint #11240973 — 2018 GMC TERRAIN

WHEN VEERING OR STEERING INTO ANOTHER LANE, LEFT OR RIGHT, THE SAFETY ALERTS, I.E. THE TUG OF THE STEERING WHEEL AND VIBRATION OF SEAT, ARE NOT WORKING PROPERLY. FOR THE FIRST YEAR OF OWNERSHIP OF THIS VEHICLE, THIS FEATURE WORKED FINE. HOWEVER, IN THE PAST FEW MONTHS, IT HAS QUIT WORKING OR WORKS SPORATICALLY BUT WHEN WORKING SPORATICALLY, DOES NOT WORK AS IT SHOULD. THE DEALERSHIP WHERE I PURCHASED IT IS UNABLE TO FIX IT STATING THAT IN "UPDATING" THE PROGRAMMING IN MY CAR, THIS FEATURE WAS WEAKENED (DILIBERATELY BECAUSE GMC INTENDED TO WEAKEN THE FEATURE STATING THE REASON WAS BECAUSE SOME DRIVERS WERE USING THIS FEATURE AS AN AUTO-DRIVE). I BOUGHT THIS VEHICLE, ONE OF THE REASONS BEING THAT IT OFFERED THIS FEATURE AND NOW THE FEATURE DOESN'T WORK THE WAY IT DID WHEN I BOUGHT IT.
