Mercedes-Benz USA CEO Dietmar Exler has informed Automotive News that availability of the redesigned 2017 E-class sedan has been delayed as the company awaits regulatory approvals. The automaker was unable to confirm whether the certification holdup rests with the Environmental Protection Agency, the California Air Resources Board or both organizations.

Initially expected to be delivered to dealerships in June, Mercedes now anticipates that the certifications will be granted within two weeks, allowing the 2017 E300 to be launched at the end of July.

U.S. sales of the E class declined 25 percent to 49,763 vehicles in 2015. Through the first five months of 2016, sales have dropped an additional 13 percent as Mercedes sells off the remaining inventory of the outgoing model.

Update: Automotive News reports that the 2017 E-class sedan has received its certification approvals and is being delivered to U.S. dealerships.
