Multiple recalls through the years for defective EGR lights. Should I be worried

Owner, EGR ( Exhaust Gas Recirculation ) is an emissions system which helps to control combustion temperatures, therefore limiting the creation of Oxides of Nitrogen in the vehicle exhaust. When the EGR system is not working, most vehicles also have a slight decrease in performance and fuel economy, as well as an increase in pollutants from the exhaust. There may be a fix at your dealer involving a later program which can be installed in your vehicle's Processor, which may be a no-charge procedure. If you have tried multiple times to have this issue resolved, I would suggest an alternate Dealer Service Department.
