“So far there has not been any accidents caused by the cold start problem my car is having. The 2003 Kia RIO cinco has been in the shop numerous times for the same cold start problem. In the 1.5 years I have had the car I have nothing but problems with it. They have stated that the problem is fixed every time, however it continues.”

The consumer was informed by the mechanic that the odor the driver was smelling was called kosmoline and would eventually disappear. There was a nauseating smell of burning rubber or plastic from the time of purchase. The consumer was allergic to the smell after breathing the melting kosmoline and or undercarriage for over 3k miles. The smell had come from the vents as well when the vehicle was stopped. …”
