2008 Cadillac STS V8 with 18k miles that produces puffs of smoke from tailpipes...does this seem normal to anyone? Per Sewell, it is normal. I asked to speak to a Service Manager as I was not satisfied with diagnosis. They have 7 similar STS's on their lot and asked manager to start each one of them & show me they ALL smoke. After all if it is so normal the other vehicles should smoke. Service Managers agrees to start other vehicles when I arrive. I arrived at Sewell and met Service Manager. He was a JERK. He demanded the smoke was from condensation. It was obvious they were unable to duplicate the smoke I was talking about because I know the difference between steam & a cloud of smoke. Basically he kept implying I did not know what I was talking about & all Cadillacs smoked.\r
Very unhappy with Service Manager & plan on contacting Corporate Office Today.
