2015 NISSAN ARMADA Steering Problems

WHILE DRIVING ON THE HWY VEHICLE HITS A ROUGH PATCH. FEELS AS IF ITS HYDROPLANING, BUT CORRECTS TO OVER CORRECT ITSELF. VERY UNSAFE MAIN VEHICLE FOR TRANSPORTATION. FIRST OCCURRENCE WAS JUNE 2018 , AND ANYTIME I TRAVEL THE ONTERSTATE AND HIT A BAD PATCH OF ROAD. LAST INCIDENT 29 DEC 2018. BROUGHT DEALERSHIP, NOTHING FOUND.

THE VEHICLE HAS BEEN REPAIRED 22 TIMES. ISSUES RANGED FROM COMPUTER TO STEERING ISSUES. ON MORE THAN 1 OCCASION, THE VEHICLE HAS BEEN AT THE DEALERSHIP BEING REPAIRED FOR THREE WEEKS OF MORE IN A SINGLE MONTH. DURING A RECENT ROAD TRIP, THE VEHICLE WAS HARD TO CONTROL ON THE ROAD; THE STEERING WOULD DIFFICULT TO KEEP THE VEHICLE IN THE LANE DURING TURNS, WHILE ON THE HIGHWAY AND COULD NOT DRIVE AT HIGHWAY SPEEDS. MY STEERING WHEEL IS NOT STRAIGHT, EVEN AFTER THE RECENT WHEEL ALIGNMENT WHEN THEY DISCOVERED THAT I DID NOT HAVE CAMBERS INSTALLED ON THE FRONT END. THE NISSAN DEALERSHIP WHERE I PURCHASED THE VEHICLE NEVER ASSISTED ME, AND NOW NISSAN IS OFFERING TO REPURCHASE THE VEHICLE, BUT WOULD LIKE FOR ME TO PAY THEM $18K. I AND MY FAMILY ARE COMPLETED EXHAUSTED WITH THIS MATTER, ESPECIALLY AFTER OUR TRIP THAT SHOULD HAVE TAKEN 20 HOURS...
