Steering Column problems of the 2015 Hyundai Elantra

Hello purchased 2015 Elantra used with 29,000 miles had steering issues along with bad tires,we experience a situation in the steering like the car cannot drive straight without making constant left or right adjustments in the wheel to keep in the lane, almost like a bicycle chain slipping on the sprocket as an example, we did take in for vehicle inspection 3 times,they said nothing wrong first time and just tightened steering column, still was faulty, so scheduled another appointment, this time a 4 wheel alignment and new tires would solve this issue,did put 4 new tires and skipped the alignment and had called Hyundai motor America corporate, they called service manager of car dealership directly to do complete vehicle inspection, nothing was wrong according to the master technician, so evidently it was going to be faulty and it is still having steering issue, as it is the design of the car for this year as mentioned by service manager. The corporate person I contacted is very seriously concerned about the safety of the vehicle, but dealership is DE sensitized I think to the situation, this is my last attempt for possible consideration,along with filing a complaint with the ftc with the issue and sales never provided the monroney window sticker, I have no comparison of the window sticker quoted sales price versus contract sales price and optional and standard equipment. As this issue is serious in my concern is driving on the highway with this situation, we do notice as well driving in town, at the present time we have to much invested in the car otherwise would trade for a newer model of the car as we did rent the 2017 Elantra se model and this issue is not apparent in the new vehicle, a noticeable difference can be felt in the newer car. Perhaps something in the steering in the 2015 is faulty or just wears out prematurely, thanks for accepting this complaint.
