BMW of North America is recalling approximately 44,300 vehicles – model-year 2013-18 BMW 328d and 328d xDrive sedans; model-year 2014-18 328d Sports Wagons and 328d xDrive Sports Wagons; model-year 2014-16 535d and 535d xDrive sedans; model-year 2015 740Ld xDrive sedans; model-year 2015-17 X3 xDrive28d SUVs; and model-year 2014-17 X5 xDrive35d SUVs.

The recall notice says that all are equipped with an exhaust gas recirculation module with an integrated cooler. The issue with the vehicles listed above is a potential internal leak of the the exhaust gas recirculation cooler which can lead to the coolant mixing with diesel engine soot.

The high exhaust gas recirculation temperatures may result in these particles possibly smoldering and melting the intake manifold, increasing the risk of a fire.

Dealers will inspect and replace the exhaust gas recirculation cooler as necessary. If a leak has already occurred, the engine intake manifold will also be replaced. Both repairs will be done for free.

BMW will begin notifying owners Dec. 17. Owners can call the automaker at 800-525-7417, the National Highway Traffic Safety Administration’s vehicle-safety hotline at 888-327-4236 or visit its website to check their vehicle identification number and learn more.
