Lexus RC350 loss of 3 MPG after dealer's factory recall service on ICS system on Lexus RC350

Some Lexus RC350 owners report experiencing a loss of 3 MPG in fuel efficiency following a dealer's factory recall service on the ICS system, which is a safety feature in Lexus vehicles. While recalls typically address safety issues that require prompt attention, some owners are concerned that the recall service may have inadvertently affected their vehicle's fuel efficiency. It is important to note that recalls may not directly impact MPG, but owners are encouraged to investigate other potential factors influencing their fuel economy, such as driving conditions and maintenance issues. Consulting with a Lexus dealership or a qualified mechanic for a thorough inspection may help identify the cause of the decreased fuel efficiency.
