NHTSA Complaint #11228574 — 2017 CADILLAC XTS

PROBLEM #1 - TRUNK OPENS BY ITSELF (SOMETIMES WHILE VEHICLE IS STATIONARY & LOCKED (I.E., PARKED FOR THE NIGHT - ENGINE OFF); OTHER TIMES THE TRUNK OPENS BY ITSELF WHILE I AM DRIVING/MOVING (ENGINE OBVIOUSLY ON); OTHER TIMES WHILE THE ENGINE IS ON AND THE VEHICLE IS STATIONARY (I.E., VEHICLE IS AT IDLE). I KNOW FOR A FACT THAT THESE EPISODES OCCURRED WITHOUT ME PRESSING THE TRUNK BUTTON - WHETHER IT BE THE INSIDE/DOOR TRUNK BUTTON; KEY FOB TRUNK VUTTON; OR THE TRUNK RELEASE ON THE TRUNK ITSELF. IT IS A SAFETY HAZARD TO HAVE THE TRUNK SUDDENLY OPEN WHILE DRIVING AT 70 MPH OR WHILE DRIVING AT 35 MPH (CAN HAPPEN AT ANY SPEED, INCLUDING 0 [ZERO]). IT IS A SECURITY MATTER AS WHEN PARKED AND THE TRUNK OPENS BY ITSELF, IT LEAVES ME VULNERABLE TO THEFT OF MY PROPERTY. PROBLEM #2 - DRIVER DOOR LOCK. THE DRIVER'S DOOR MYSTERIOUSLY UNLOCKS AT TIMES (ONLY THE DRIVER'S DOOR UNLOCKS -- THE OTHER 3 DOORS REMAIN LOCKED) - . SO FAR, THIS ONLY OCCURS WHILE THE ENGINE IS OFF AND THE VEHICLE IS STATIONARY AND PARKED. I HAVE NOTICED BY NOW THAT ON OVER 10 OCCASIONS, MY DRIVERS DOOR (ONLY) IS ALREADY UNLOCKED WHEN I APPROACHED THE VEHICLE. THE "PASSIVE LOCK" FEATURE IS ON, SO THE CAR AUTOMATICALLY LOCKS ITSELF AS I WALK AWAY FROM IT (AND I ALWAYS LISTEN FOR HORN CHIRP WHILE WALKING AWAY INDICATING THAT THE CAR HAS LOCKED ITSELF). OTHER TIMES, I DOUBLE-CHECK THE LOCKING BY EITHER USING THE KEY FOB OR DEPRESS THE INSIDE POWER LOCK POWER DOOR LOCK SWITCH OR PRESS THE UNLOCK/LOCK SMALL BUTTON ON THE EXTERIOR DRIVER DOOR HANDLE. WHEN I FIND THE DRIVER'S DOOR UNLOCKED, IT IS IMPOSSIBLE FOR ME TO MANUALLY RE-LOCK THE CAR. IF I PRESS THE INTERIOR POWER DOOR LOCK BUTTON, ALL 4 DOOR LOCKS LOCK MOMENTARILY, THEN ALL 4 DOORS UNLOCK THEMSELVES - (SO NOW ALL 4 DOORS ARE UNLOCKED). THE ONLY WAY FOR ME TO LOCK THE CAR AT THIS POINT IS TO USE THE KEY FOB.
