“I had just filled gas tank with unleaded gas. When I noticed a strong gas smell. The car sits all day. I only move it for emissions each year I work from home. They tested and told me evap emission control sys malf. The guy said he could see gas leaking from my fuel line. He said it was a recall on this to check with Kia. Kia told me my VIN number did not match the recall. This car does not see alot of action there is no reason other than a few good snows that may have rusted the tank other wise why would my tank all of a sudden leak gas. …”

“I have a 1999 Kia Sportage with less than 35,000 miles on it as of july 5, 2006. In november of 2005 I started noticing a really strong fuel smell. Shortly thereafter I noticed fluid leaking from the rear of my vehicle. I took it in around thanksgiving to find out that the gas tank had to be replaced. I had to pay almost $1,000 for this repair. Also, in may of 2006 power steering fluid leaked all over my garage while the car was in summer storage. Upon further investigation it is due to the power steering pressure hose damping pipe rusting out. …”
