Engine complaints
On January 29, 2020, while driving my 2016 BMW 5 Series under normal operating conditions, the engine compartment caught fire without warning. Smoke and flames originated from the engine bay while the vehicle was in motion. I was forced to pull over and exit the vehicle immediately. The fire spread rapidly, and the vehicle was declared a total loss. At the time, both my insurance carrier and BMW representatives inspected the vehicle, but no definitive cause was identified. In January 2026, I received notification...

that this same vehicle is subject to BMW Safety Recall Campaign No. 24V-608, which states that liquid from the positive crankcase ventilation system can drip onto the water pump electrical connector, potentially causing a short circuit and, in rare cases, an engine fire. This recall describes the same failure event that destroyed my vehicle, which occurred before any recall remedy was available.
My coolant line overheated. From the leaking water pump and pcv that exploded all over my engine causing it to overheat and now how has not turned back on. Ive been without a car for months and when I seen the recall and reached out to the dealer expressing my situation they said they would get back to me and have not called or emailed or even responded in months.
During initial cold starts there is blue smoke billowing from the exhaust for approx 20 seconds. The odor is horrible.
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.
Coolant pump failure engine failure also caused fire in engine bay. Insurance inspector. Pre shop inspection. No light were on prior to explosion.
On [[redacted]], the coolant connector flange on my 2016 BMW 535d (VIN: [[redacted]] ) 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, [[redacted]], 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.

Very often, when I change the gear to 'Drive' or 'Reverse' I get a message on the dashboard screen - "secure Vehicle against rolling" and the car DOES NOT move unless I shift the auto gear lever several times or sometimes shut off the engine to get back to normal driving. Once when I was in such a situation, no matter what I do, the error message would not go away and I had to call the tow truck to get home. And when tow truck person brought the car home, the problem fixed itself!! I only have 81000 miles on this car. It is a very serious safety issue as far as I am concerned. PLEASE HELP.

My vehicle is a 2016 BMW 528i xDrive. There is an active safety recall listed under NHTSA Campaign Number 24V-608, issued in August 2024. The affected component is the engine coolant pump. As of June 2025, no remedy has been made available by BMW, and I have been told by both BMW corporate and my local dealer that they cannot provide a fix or a timeline. This component is essential to keeping the engine within safe temperature limits. Failure of the coolant pump could lead to overheating and potentially increase...

the risk of fire, as the recall suggests. This places my safety and that of others on the road at risk every time I drive the vehicle. I rely on this car for regular transportation and feel I have no choice but to drive a vehicle with an unresolved critical safety issue. The vehicle has not yet experienced a failure or warning light specific to the coolant system, and it has not been inspected or repaired due to the lack of remedy. However, I should not be forced to wait indefinitely or risk a dangerous situation developing before action is taken. BMW's failure to provide a remedy or meaningful updates in nearly a year shows a lack of urgency and accountability. I am submitting this complaint to formally document the issue and ask that NHTSA take action to compel BMW to issue a fix or provide alternatives to affected owners.

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.

I've gotten my car fixed multiple times and nothing has worked. My car is leaking coolant severely it overheats constantly I get the red and the yellow message. My heater is self stopped working and my car on the freeway has stopped from going 75 to 80 miles dropping all the way to 20 miles.
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.
