WAS DRIVING A BRAND NEW HYUNDAI SONATA 2018 VEHICLE FOR A WEEK WITH 300 MILES ON IT AND WAS ABOUT TO EXIT ON A FREEWAY RAMP, BUT SUDDENLY LOST CONTROL OF THE STEERING. THE VEHICLE HAD TO BE TOWED AND WHEN THE MECHANICS AT THE HYUNDAI DEALERSHIP TOOK A LOOK AT THE VEHICLE, THEY WERE UNSURE OF HOW THE LOWER ARM ASSEMBLY ON THE FRONT DRIVER'S SIDE (FRONT SUSPENSION CONTROL ARM) WITH THE BALL AND JOINT CONNECTION WAS DISCONNECTED, WITHOUT HAVING ANY SCUFFS/SCRATCHES ON THE ARM ASSEMBLY OR FRONT BUMPER IF SOMETHING WERE TO HAVE BEEN RUN OVER, BUT HYUNDAI REFUSES TO ADMIT ANY FAULT AND DISREGARDS ANY POSSIBILITIES OF PRODUCT ISSUES AND PUTS THE BLAME ON DRIVER. THE PICTURES TAKEN SHOW NO SCRATCHES OR SCUFF MARKS DIRECTLY TO THE CONTROL ARM, NOR THE BUMPER OF THE VEHICLE, WHICH DENIES THAT A COLLISION COULD HAVE RESULTED IN THE DAMAGE, YET HYUNDAI BELIEVES THAT THERE WAS A COLLISION PER THE DRIVER THAT CAUSED THE DAMAGE. THIS IS A SERIOUS ISSUE ESPECIALLY SINCE IT OCCURRED WHILE THE VEHICLE WAS IN MOTION. HAVE BEEN TRYING TO UNDERSTAND HOW THIS HAPPENED, BUT HYUNDAI ONLY PROVIDES VAGUE RESPONSES TO CLAIMS AND QUESTIONS AND FAILS TO PROVIDE ANY SOLID EXPLANATIONS REGARDING THE ACTUAL ISSUE OF THE LOWER CONTROL ARM ASSEMBLY AND SIMPLY DICTATED THE RESULTS OF THEIR INSPECTION AS "NO ISSUES WITH THE BRAKING OR STEERING SYSTEMS" WHEN I SPECIFICALLY HAD AN ISSUE WITH THE LOWER ARM ASSEMBLY PART. CURRENTLY HAVE AN ON-GOING CASE WITH HYUNDAI CONSUMER AFFAIRS (#10727408) WITH NO HELPFUL OR ACCURATE EXPLANATIONS OR ACKNOWLEDGMENT OF THE SAFETY ISSUE AT HAND FROM HYUNDAI.
