    Just got notification regarding a software "improvement" regarding my 2011 Sonata LTD. 2.0 Turbo. I'm always suspicious about these kinds of "improvements". There has been concern in the past about connecting rod bearing wear and I earlier received an extended engine warranty because of it. An engine ECU adjustment CAN be a detuning setting to reduce engine stress which often results in reduced horsepower (i.e performance!) and reduction in MPG. I'm perfectly happy with my car as it is and don't wish to sacrifice performance or MPG's to just satisfy the factory's fear of potential profit loss due to warranty fixes. Can anyone tell me the real story? Will my performance or fuel economy suffer if I have this fix done?
