Kia india - recurring unsolved repairs

i bought kia carens top end manual fro simha kia outlet dealer vijayawada on september ****, i have changed my car tyres on september **** from mrf to continental,since then my car started showning hard suspension problem and steering column sounds and hard steering and left pulling ,i have been several times to the service centre with the same problem ie,. from ***** km mileage to ***** km mileage ,but the service providers couldnt solve my problem and they used to touch up the problems and send my car ,and on the same day before reaching home from the workshop all the problems would reappear which were not found in the trial run ,due to my hectic schedule i could not go around and make the care repair immediately and i would go again after some days they would do the same and send me back but the problem presists ,if i want to get that done i must leave the car for atleast one month although its a one day work the workshop people would demand for atleast a week ,but its impossible for me.
my car has total four wheels suspension issue
steering column and axles problem
left pulling problem
tensioner wheel problem
diesel filter combustion problem
these are the recourring problems which are not being solved and repaired i want them done immediately on company's warranty policiy or otherwise give me a brand new car incase if they failed to do .#kiacarens #KIAINDIA
