DELAYED ACCELERATION FROM STOP. VERY UNSAFE WHEN MAKING A LEFT HAND TURN AS IT WILL TAKE UP TO 10 SECONDS FOR THE CAR TO ACCELERATE. THIS HAPPENS OFTEN BUT NOT ALWAYS. I DO NOT FEEL SAFE DRIVING THIS CAR.
AFTER ACQUIRING A LITTLE OVER A MONTH (1167 MILES ON IT) THIS CAR FAILED WHILE I WAS DRIVING ON A MAJOR HIGHWAY AND HAD TO NAVIGATE OVER 4 LANES FROM JUST MOMENTUM - COULD NOT USE MY CELLPHONE AS IT WAS TRYING TO SYNC TO THE CAR WHICH WAS NOW COMPLETELY DEAD. TOWED TO PURCHASING DEALER AND WAS DIAGNOSED AS BAD GROUND WIRE. I AM TERRIFIED TO DRIVE THIS CAR AGAIN, MY PASSENGER AND I COULD HAVE BEEN INJURED OR WORSE.
HYUNDAI 2018 HAD A OIL LEAK ISSUE DUE TO A FAULTY OIL PAN. THE OIL PAN WAS SEALED BY THE DEALERSHIP. THIS DID NOT SEEM TO FIX THE ISSUE CAUSING THE OIL TO DRAIN ON THE FREEWAY AND SEIZE THE ENGINE. I WAS COASTING ON THE FREEWAY WITH NO POWER FROM THE ENGINE. WE WERE SCARED FOR OUR DEAR LIVES.
