2016 BMW 5 Series Engine Problems

The contact owns a 2016 BMW 528i. The contact stated that the vehicle was repaired under an unknown recall, and after the recall repair, while driving at an undisclosed speed, there was an abnormal oil-burning odor entering the cabin of the vehicle. The vehicle was taken to a local Midas, where it was discovered that oil was leaking onto the engine. The vehicle was not repaired due to the cost. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 32,400.

Multiple critical BMW engine components are manufactured from plastic, including the oil pan, coolant expansion tank, valve cover, and turbo inlet pipe. These parts are prone to premature failure from normal heat & stress, as confirmed by independent mechanics. Failures can cause sudden loss of oil or coolant, persistent oil leaks, overheating, loss of power, and roadside breakdowns. The use of plastic for an oil pan is concerning. Plastic cannot withstand impacts with common road hazards such as tire fragments, etc. Striking a retread at highway speed could easily crack the pan, dump all engine oil, and lead to catastrophic engine seizure, endangering people. In my case (2016 BMW 528i), several plastic components have already failed, including the oil pan, turbo inlet pipe, coolant expansion tank, valve cover, and multiple coil packs. While BMW considers coil pack replacement a normal maintenance item, there are widespread complaints of premature failures. Most of the heat-related plastic failures occur above 70,000 miles. Despite several related breakdowns, the previous owner and I avoided dangerous situations. These failures are widely documented by other owners online and by independent mechanics, who often recommend aftermarket aluminum replacements for improved safety and reliability. BMW is aware of these issues but continues to use plastic for critical components--they recently lost a class-action lawsuit related to internal plastic engine parts that caused catastrophic engine damage, showing prior knowledge of the risks. These failures also create environmental hazards, as leaking plastic oil pans & valve covers contaminate roads and driveways. Because repairs are $$$, many consumers delay fixing the problems, increasing both safety and environmental risks. This design prioritizes cost savings over durability and safety. These parts should be made of metal to withstand normal use and protect drivers, passengers, and the public from unnecessary hazards.

During initial cold starts there is blue smoke billowing from the exhaust for approx 20 seconds. The odor is horrible.

On [XXX], the coolant connector flange on my 2016 BMW 535d (VIN: [XXX] ) catastrophically failed, causing complete coolant loss. I immediately contacted BMW of Las Vegas and was instructed to drive it in despite fluid visibly leaking through the undercarriage. The next day, [XXX], BMW performed Recall 21V-907 (EGR cooler replacement), which involved draining and reconnecting the coolant circuit—but they left the failed flange in place. The failed flange connects directly to the new EGR coolant return hose installed under the recall. BMW had full access to the part but chose not to inspect or replace it. The dealer submitted a consequential damage claim to BMW North America, which was denied. The vehicle remains at the dealership unrepaired. This failure poses serious safety risks. Driving with active coolant loss could cause overheating, engine failure, or fire. Had I not stopped, this could’ve led to mechanical catastrophe. BMW re-pressurized the cooling system into a visibly broken flange, creating an unsafe condition. The failure was confirmed by BMW technicians and documented in a repair order. No warning lamps were active at the time of failure. I currently have an open case with BMW North America, but no contact has been made. I am requesting NHTSA review this matter as BMW failed to fully remedy a safety defect and ignored collateral damage tied directly to the recalled system. The failed part is available for inspection.

Concern- smoke coming out of back exhaust at start up Cause - TAYLOR BMW (dealership) - possible needs updated oil line, turbo may be leaking internally Correction- dealership pulled faults to see if cat efficiency faults were present, saw none. Did verify smoke on startup. Doesn’t look like the turbo oil feed line has been changed (updated with check valve). There is some oil encrusted on the body of turbo. Would replace all lines since turbo removal is required for any of them; however once cat is off and if the chamber inside is wet with oil, at that point it would need a turbo as well as the lines. The above is the written diagnosis from dealership and I was quoted a price ranging from $2600- 4600- In 2016, NHTSA issued a notice for certain models/ years regarding the turbocharger feed lines (extending warranty for that part to 10 years / 120k miles). My 2016 was CPO and has only 84k (all maintenance performed by BMW) and I believe it should fall under eligible vehicles. I have reached out to BMW customer care, spoken with a case manager , all to no avail.

Valve cover leak Oil filter housing leak Super common that these items leak in the bmw N57 diesel engines. Increased risk of fire. I am in the Facebook group with many other owners of the same engine, and almost everyone runs into the same problems by 100,000 miles.
