Hi....we have a sorento and have experianced the same pulling to the left and extreme frpnt tyre wear rates.
After having the traking checked by the dealer due to the front off side tyre outer wear we ended up with both front tyre wearing on the inner edges.
A further check today at another dealer confirms tracking within specification but they want the vehicle in for three days to diagnose the problem.
Kia Uk advised me on the phone that I will have tpay for the new tyres ', perhaps not.
Does any one who has experianced this issue have an answer to rectify it.
Regards
Peter
