TL* THE CONTACT OWNS A 2017 KIA OPTIMA. THE CONTACT STATED THAT THE SUN ROOF EXPLODED WITHOUT IMPACT WHILE PARKED IN THE GARAGE. THE CONTACT STATED THAT WHILE IN THE HOUSE SHE HEARD AN ABNORMALLY LOUD BOOMING SOUND. THE VEHICLE WAS NOT TAKEN TO A DEALER OR AN INDEPENDENT MECHANIC FOR DIAGNOSTIC TESTING. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 37,300.
I CAN NOT SEE THE CAR ON THE RIGHT IF I WANT TO SWITCH LANES ON A HIGH WAY. IN TRAFFIC I GET NOT ZOOM IN AND OUT OF LANES, EITHER I (THE DRIVER) OR THE PASSENGER NEEDS TO TURN THEIR HEAD IN ORDER FOR THE DRIVER TO TURN RIGHT. I TRIED THE LITTLE MIRRORS THAT YOU STICK ON BUT THAT DID NOT WORK. WHEN I TEST DROVE IT, I DID NOT REALIZED IT FOR I DROVE IT REGULAR ROADS
THE REAR VIEW MIRROR IS SITUATED TOO LOW, CREATING A LARGE BLIND SPOT IN THE CENTER OF THE WINDSHIELD. OFTEN, AT A 4-WAY STOP, THE CAR APPROACHING FROM THE RIGHT IS COMPLETELY BLOCKED OUT. DRIVER IS FORCED TO CROUCH DOWN SO AS TO LOOK UNDER THE MIRROR IN MANY DRIVING SITUATIONS. THIS HAS NEARLY CAUSED AN ACCIDENT A NUMBER OF TIMES.
WAS DRIVING THROUGH A TUNNEL WHEN I HEARD A LOUD POP, AND THEN THE SOUNDS OF GLASS SHATTERING AND WIND. THE SUN ROOF OF MY CAR WAS COMPLETELY CRACKED. THE INTERIOR SUN SHADE WAS THE ONLY THING THAT PREVENTED ME FROM HAVING A GLASS SHOWER.
