The EV-6 GT auto experienced a loud clunking grinding noise while steering 180 degrees when turning right and then left. The car skidded on the pavement this happened over a period of 3 months when the temperature was below freezing. After 2 service appointments Bridgewater NJ KIA dealership failed to diagnose the problem . On the 3rd visit they confirmed that the noise emanated from the summer performance tires that caused the tires to skid and caused the noise. Their solution was that storm tires would need to be replace the existing summer tiresThe existing tires are Good Year 255/40R 21. Not only that Good Year ds not make snow tires of this size but when I first leased the car I was not told that the car would need snow tires to prevent skidding from snow or icy road conditions. There failure to notify car owners in the northeast of this hazard puts drivers at risk and potential for accidents in cold weather temperatures. Since I have not driven the leased car in below freezing temperatures and risk safety and hazards from driving on these summer tires I believe KIA should be held responsible for failure to notify drivers of this condition. I plan to terminate early the 3 year lease and also withhold payment until KIA acknowledges that they failed to identify this safety hazards and then did not offer to replace these tires to prevent future accidents. These summer tires were also Not clearly defined as racing tires with inability to provide adequate tread on icy and snowy road conditions. I am submitting this claim to prevent potential car accidents in driving the car in the northeast were weather conditions are periodic snow and icy conditions.
