I was the owner of a 2018 Sonata until I was t-boned and the car was totaled. I started to make a left turn into a school parking lot when the engine kind of stalled or more like stuttered and did not go forward as usual. The oncoming car then struck me before I was completely in the driveway. My vehicle was totaled as was the other one. Fortunately no one was on the passenger's side where the other car hit me. However the seat belt did not engage which resulted in me slamming very hard into the steering column. This resulted in bruised on my right side which cleared up in several weeks, but, unfortunately, I received a heart contusion on my left side which is still causing shortness of breath. Hyundai will not acknowledge a problem with the engine or the seat belt.

The passenger side seat belt locks up. It can lock up immediately when putting it on or it can lock up if I just lean a little bit forward. It will get tighter and tighter to the point where it is very uncomfortable. I have to unhook the seatbelt and re hook. Sometimes this takes many attempts. This is scary when you are going down the highway at 65mph. The dealership has replaced it twice. They were able to see the problem because my husband drove straight to the dealership once when it locked up on me. The last time they replaced it, no one was in the passenger side until we were leaving for vacation. We didn't even get out of the garage when it locked up again. The dealership was reluctant to replace it. They said all seat belts lock up! Because of Covid my husband and I haven't driven much. Once we started going out again we became aware of the problem.

WHILE DRIVING 30MPH APPROACHING A RED LIGHT, MY 2018 SONATA CUT OFF ONCE I CAME TO A COMPLETE STOP AT THE RED LIGHT. I WAS IN CITY LIMITS APPROACHING A HWY INTERSECTION. THE CHECK ENGINE LIGHT CAME ON AND THE CAR RESTARTED AFTER ONE ATTEMPT. ONCE THE VEHICLE RE STARTED IT WAS SLUGGISH,SPUTTERING AND WOULD NOT ACCELERATE OVER 20MPH... I MADE IT HOME SAFELY NONETHELESS. I LEFT THE CAR PARKED FOR APPROX 10 MINS AND IT RESTARTED EASILY. I THEN DROVE IT DIRECTLY TO THE LOCAL DEALER WHERE THE CAR WAS PURCHASED. I WAS TOLD THE CAR STOPPED BECAUSE THE ENGINE SYSTEM REQUIRED AN UPDATE. THE UPDATE WAS COMPLETED AND I DROVE THE CAR HOME. THE NEXT DAY OR MAYBE TWO DAYS LATER I RECEIVED A LETTER FROM THE DEALERSHIP SAYING MY CAR REQUIRED A FREE RECALL AND TO SCHEDULE A DATE TO HAVE THE CAR SERVICED. OVER THE PHONE I WAS TOLD SOMETHING ALONG THE LINES OF THE ENGINE HARNESS NEEDED TO BE REPLACED. WHEN THE CAR'S ENGINE CUT OFF IN TRAFFIC I WAS EN ROUTE TO PICKING UP MY TODDLER. I NO LONGER FELT SAFE DRIVING THE VEHICLE AND I TRADED THE CAR IN AND CUT MY LOSSES, WHICH WERE SUBSTANTIAL. OTHER PROBLEMS I NOTICED IN THE TIME I HAD THE VEHICLE WERE THAT THE BACK PASSENGER SEAT BELT LOCKED OR ANCHORED IF I LEANED FORWARD SLIGHTLY AND LOW VISIBILITY AT NIGHT THROUGH THE FRONT WINSHIELD.

ORIGINALLY, THE SEAT BELT WOULD LOCK UP AND NOT RELEASE AS WE WERE DRIVING. NO SUDDEN STOPS, IT WOULD JUST TIGHTEN UP AND LOCK. SERVICE DEPT FINALLY REPLACED THE ENTIRE UNIT (SO THEY CLAIM). NOW WHEN PASSENGER PULLS BELT TO ATTACH WE HEAR A CLICKING SOUND AND BELT LOCKS AND WILL NOT RELEASE AND ALLOW PASSENGER TO LEAN FORWARD LIKE THE DRIVERS BELT DOES
