Safety recalls — NHTSA campaigns

25V700000 2025-10-15

Fuel system, diesel

BMW of North America, LLC (BMW) is recalling certain 2018 328D SportsWagon, 328D xDrive SportsWagon, 328D xDrive, and 328D diesel vehicles equipped with an exhaust gas recirculation (EGR) module with an integrated cooler. The EGR cooler may leak internally, causing coolant to mix with diesel engine soot, which could result in smoldering particles and a melting intake manifold.

Smoldering particles and a melting intake manifold increase the risk of a fire.

Fuel system, diesel

BMW of North America, LLC (BMW) is recalling certain 2013-2018 328d, 328d xDrive, 2014-2018 328d Sports Wagon, 328d xDrive Sports Wagon, 2014-2016 535d, 535d xDrive, 2015 740Ld xDrive, 2015-2017 X3 xDrive28d SAV, and 2014-2017 X5 xDrive35d SAV diesel vehicles equipped with an Exhaust Gas Recirculation (EGR) module with an integrated cooler. The EGR cooler may leak internally, causing coolant to mix with diesel engine soot, which could result in smoldering particles and a melting intake manifold.

A melting intake manifold increases the risk of a fire.

18V755000 2018-10-25

Engine and engine cooling:exhaust system:emission control:gas recirculation valve (egr valve)

BMW of North America, LLC (BMW) is recalling certain 2013-2018 BMW 328d and 328d xDrive, 2014-2018 328d Sports Wagon and 328d xDrive Sports Wagon, 2014-2016 535d and 535d xDrive, 2015 740Ld xDrive, 2015-2017 X3 xDrive28d SAV and 2014-2017 X5 xDrive35d SAV vehicles equipped with an Exhaust Gas Recirculation (EGR) module with an integrated cooler. If the EGR cooler leaks internally, the coolant can mix with diesel engine soot. The high EGR temperatures may result in these particles possibly smoldering and melting the intake manifold.

The melting intake manifold can increase the risk of a fire.

In owners’ own words

Engine 21,000 mi 2.8 yr in service crash / fire / tow

I WAS STOPPED AT A STOP LIGHT WITH MY FOOT ON THE BRAKE FOR ABOUT A MINUTE WHEN THE CAR SUDDENLY ACCELERATED AND LUNGED FORWARD.I APPLIED MORE PRESSURE TO THE BRAKE,ALL THE WAY TO THE FLOOR , BUT THE CAR WOULD NOT STOP. THE CAR IN FRONT OF ME IS THE ONLY THING THAT STOPPED THE CAR ,AS HE WAS STOPPED TOO. THE CAR THEN BOUNCED BACKWARD AND TURNED OFF BY ITSELF. I WAS ON A MAIN STREET AT A LIGHT. IT WAS FORTUNATE THAT ANOTHER CAR WAS STOPPED IN FRONT OF ME BECAUSE IT STOPPED THE CAR AND PREVENTED MY CAR FROM HITTING PEDESTRIANS.

Engine mileage not reported 7.7 yr in service

Was simply driving my vehicle to work. It started overheating parked it right away before it got worse as the car alerted had it towed to a shop. The shop informed me that the motor was blown in the pistons went through the motor something with the oil the mechanic and I were looking further into this and it looks like my make and model in year had some recalls about the motor overheating in the past so I would really like this looked into as this might be a recall Iâm not sure what else this could be or why this would happen with such low miles

Engine mileage not reported 8.9 yr in service

Engine seized on freeway. Car has 99,000 miles. Dealership says engine seized and has to be replaced at a higher cost than the car is worth. Unknown warning lights.

How to read this

This is what owners reported, not a reliability rating. People file with NHTSA about alarming failures, not routine ones, and complaint volume tracks how many cars were sold.
Failure ages come from the incident date on each complaint, populated on about 83% of records. Mileage is shown where reported — NHTSA’s 2021 system change cut mileage capture to roughly 15%, so it thins out sharply after MY2020.
Every rank compares this vehicle only against others of the same model year. A 2025 car has not had time to accumulate five-year failures, so comparing early-failure share across years is meaningless.
Fourteen make-months distorted by media storms and mass recalls — Toyota in February 2010 ran 11× normal volume across 33 models — are excluded.
Recalls are manufacturer actions and authoritative; complaints are not. A recall listed here may already have been performed on any individual car. Check a specific VIN at nhtsa.gov/recalls.
