2013 BMW 528XI Engine Problems

I am submitting this report to notify the National Highway Traffic Safety Administration of a safety‑related defect involving the BMW N20/N26 engine timing chain assembly. My vehicle experienced a sudden and complete engine failure at highway speed due to a timing chain malfunction. This failure occurred without warning and created an immediate safety hazard for my [XXX] son, who was driving at the time. Loss of engine power at speed eliminated the ability to accelerate, maintain speed, or safely maneuver, exposing him and surrounding motorists to significant risk. This issue is not an isolated incident. BMW has issued internal service bulletins acknowledging premature timing chain wear and failure in N20/N26 engines. Independent technicians, consumer forums, and numerous owners have documented identical failures, often occurring well before the expected service life of the timing chain. The nature of the defect—catastrophic engine failure without warning—presents a clear safety concern rather than normal mechanical wear. BMW has declined to provide assistance, stating that “there is nothing we can do,” despite the well‑documented history of this defect and its safety implications. The failure of a known defective component at highway speed is foreseeable, preventable, and materially compromises vehicle safety. I am requesting that NHTSA investigate this recurring timing chain defect in BMW N20/N26 engines, including: The frequency of sudden engine failures Whether BMW’s internal documentation reflects awareness of a systemic safety issue Whether the defect warrants a recall or other corrective action to prevent further incidents This failure placed a young driver in a dangerous situation and could easily result in collisions, injuries, or fatalities. I am submitting this report to help ensure that other drivers are not exposed to the same risk. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My 2013 BMW 528i was serviced under recall 24V-608 (Coolant Pump Electrical Connector / DME). After the recall was marked complete, the car developed several serious failures: Coolant Pump / Connector (Recall Item) – The dealer refused to replace the coolant pump even though the recall notice from the government includes both the pump and connector. Shortly after, the water pump failed completely, causing “High Temperature” warnings and putting me at risk of sudden overheating and breakdown on the road. DME (Engine Control Unit) – This was supposedly updated during the recall, but it failed to detect existing problems. Before the recall, I was never warned about issues with the turbo or oil leaks. Immediately after the recall update, the car started misfiring and showing drivetrain malfunction. The recall did not prevent or detect the failures as promised. Valve Cover Gasket (Oil Leak) – After the recall, a severe valve cover oil leak appeared, causing lean air/fuel mixture, misfires, and risk of fire. Oil leaking onto engine components is a known safety hazard. The dealer admitted the gasket leak existed but refused to cover it. Turbocharger / Wastegate – The DME flagged turbo wastegate actuator problems after the recall. The turbo cannot be ordered separately from the actuator, leading to very expensive repairs. Before the recall update, this issue was not visible, so I believe the recall software either failed to detect earlier or triggered worse conditions. Because of these combined failures, the car became unsafe to drive: misfires caused loss of power, overheating warnings increased risk of sudden engine shutdown, and the oil leak created a fire hazard. An independent mechanic later confirmed the water pump failure and valve cover gasket leak, which I had to repair at my own expense. I believe the recall defect (coolant pump connector / DME) caused or contributed to the damage of the water pump, gasket, and turbocharger. BMW and the dealer refused to rep

The timing chain became stretched so that the valve timing with the pistons had been altered so that a valve face almost hit the top of a piston(one more tooth on the intake camshaft gear would have caused an impact between the piston top and a valve face causing the motor to stall and cease operation thereby causing the vehicle to lose power and possibly control). A timing chain should not stretch so as to cause a strike between a valve face and the top of a piston. Either the timing chain was of inferior quality or the automatic tensioner was inadequate to take up the slack as the chain wore.

-Drivetrain warning message was displayed, indicated to drive moderately, and moments later car sputtered and ceased to operate. Mechanic inspected and reported the timing chain failed and is to blame. Also, the engine may be impacted due to fraying parts that may have entered engine values over the course of time. Vehicle may be available for inspection for a short period of time (sold car to mechanic for very nominal amount). -My teenage daughter was driving the car when the above occurred and broke down on a busy highway. Thankfully, she avoided a collision. The police were called and the car towed. This could have been extremely harmful to both my daughter and the general public. -An independent mechanic diagnosed the issue and confirmed the issue. -The vehicle was not inspected by the manufacturer, police, or insurance. The manufacturer (BMW) did perform an extensive evaluation and repair of the coolant line approximately two months ago but did not mention this issue. -I believe the drivetrain warning displayed once or twice with a message to drive moderately. On recollection, this was after the visit to fix the coolant issue. -We purchased the car new in 2013, were the only owners, and I expected much more from BMW. We are very upset given the potential harm that could have occurred. Also, I have since read about a class action lawsuit impacting this very same issue and pertaining to our year, make, and model. We were not informed of this lawsuit, nor did we receive a recall notice for the defective timing chains in these models. I took a substantial loss on this vehicle as compared to its FMV had this not occurred.

BMW 528i xdrive purchased new in 2013. Currently has 103k miles. While driving on hi-way at 65 mph, received "low oil pressure" alarm on instrument panel. Pulled on hi-way, engine shut-down. Initial diagnosis by local mechanic is timing chain failure. Have read COUNTLESS blogs about this being a recurring problem with the plastic timing chain degrading, 90% leading to complete engine failure - repair of which far exceeds value of car. Went to BMW dealership which didn't even bother to read the CLASS ACTION reports I presented. They had done some service work a year or so ago with no mention that this is a rather common issue. Said they would repair at my cost and that's all they can do. Ridiculous the lack of OWNERSHIP and responsibility that BMW is taking. Hopefully if enough people report BMW's behavior, an oversight agency will have enough stroke to force BMW to deal with this.

The 2013 BMW 528xi had impeccable maintenance up to this catastrophic event. The mileage was just over 80,000 miles at the time of detonation. The four-cylinder N20's plastic timing chain guide experienced catastrophic failure upon placing the car in drive, obstructing the oil pump's ability to lubricate, scorching the cylinders, and destroying the engine. BMW of North America has covertly settled a class action lawsuit regarding this issue (N20 timing chain guide), which caused this incident on my 528xi. However, no public notices were issued to current customers. Additionally, timing chains are a lifetime component; their guides should be as well unless otherwise specified in the manual. BMW of North America either installed inferior components unknowingly that do not meet their strict OEM specifications or engineered a timing chain bomb that they knowingly are aware of and are liable for all damages associated with this engineered nightmare.

The engine timing chain failed due to faulty plastic guide around the timing chain which gets brittle and brakes in the engine causing catastrophic engine failure. Our safety and the safety of others on the Parkway was put at HIGH RISK because the car goes into some safe mode and puts itself into PARK!! This three lane parkway has no shoulder to pull over on at all! So we were blocking the entire lane during rush hour traffic in NYC!! This problem was confirmed by the BMW dealership where the car is now, and they are fully aware of this issue with certain model BMWs produced between 2012 thru 2015. The vehicle was inspected by BMW Certified Mechanics at their service station. The warning light came on a min before the car shut itself down on this very DANGEROUS stretch of highway!!

Driving as normal, and came to stoplight at intersection of busy highway. Stopped for red light, and call stalled, and couldn't be restarted. Just as the car shut off, I got a Drivetrain Malfunction warning. Had to have a tow company tow vehicle to my BMW dealer 50+ miles away. Being at a busy intersection at night, and not being able to move the car (couldn't get it out of park), it put the driver at risk until assistance arrived because oncoming traffic wasn't prepared for a vehicle in the middle of the road, and not moving (even with 4-way flashers on) and having the driver stand on the roadside would have been just as dangerous. After running diagnostics, dealer stated timing belt snapped and caused engine damage. Cost of repair would be $13,000 which exceeded the value of the car; ended up buying new car with basically no trade-in value on this car and no financial assistance from BMW. Interesting enough, when I took delivery of my new vehicle, my sales person said there were 2 additional vehicles in their repair shop with the same issue.

Driving on highway got Low Oil Pressure light followed by Drivetrain Malfunction. Engine failed, managed to pull over on shoulder because road was deserted. Could have been rear ended or crashed into another vehicle if any cars were on road. Also dangerous to be stranded on the shoulder of a deserted dark highway at night. Towed to BMW Dealer and they diagnosed premature Oil Pump failure causing Timing Chain assembly to break. Said I needed an engine replacement now. This car was inspected by a mechanic who also performed an oil service change just 385 miles prior to this event. Since vehicle has over 100,000 miles, BMW NA is offering no financial assistance at all. Manufacturer placed me in an extremely dangerous and possibly fatal situation due to design flaws and defects in materials.

BMW ENGINE N20B20 KNOWN TIMING CHAIN ISSUE. THE CAR IN QUESTION IS 2013 BMW 528I XDRIVE, 4 CYL. TURBO ENGINE, AUTOMATIC, ALL WHEEL DRIVE, SEDAN. I WAS AT WORK AND STARTED DRIVING HOME, GOT OUT ON THE HIGHWAY, HIT 65 MPH AND IMMEDIATELY NOTIFIED BY THE INSTRUMENT DISPLAY THAT THERE IS POWERTRAIN ISSUE AND TO PULL OVER AND CALL SERVICE. I HAD TO TOW THE CAR HOME AND THEN AGAIN TO THE SERVICE SINCE IT WOULD NOT START. I HAD 77130 MILES ON THE CAR AT THE MOMENT. I GOT CALL FROM THE SERVICE THIS MORNING 05/29/2020 WHERE THEY STATED: CAR HAD 3 QUARTS OF OIL INSTEAD OF 5 WHICH CAUSED MECHANICAL DAMAGE AND WEAR. PLASTIC LEAD FOR THE TIMING CHAIN BROKE AND CHAIN IS LOOSE. CAMSHAFT I BELIEVE IS BROKEN. THEY ALSO STATED THAT THE FIX IS ENGINE REPLACEMENT $11,000.00. I ASKED IS THERE ANY OTHER SOLUTIONS BESIDE WHOLE ENGINE REPLACEMENT THEY SAID NO EXCEPT FOR GETTING USED ENGINE INSTEAD OF NEW. NOW I HAVE ONE MORE BMW (2007 328I, N52 6 CYL. ENGINE, 6 SPEED MANUAL, REAR WHEEL DRIVE - STILL IN GREAT SHAPE, NEVER LEFT ME ON THE SIDE OF THE ROAD 176000 MILES AND COUNTING), I AM ENTHUSIAST, I TAKE GREAT CARE ABOUT MY CARS. ALWAYS FULL SYNTHETIC OIL EVERY 5000 MILES, ALWAYS MANN FILTER(S), ALWAYS BMW SPEC LL-01 FOR US, ALWAYS CASTROL MADE IN BELGIUM. ALL THE PARTS GENUINE, BEST TIRES. WITH ALL THAT CARE I KNOW THE WEAKNESS - OIL THIRSTY ENGINES. THE CAR THAT'S IN PROBLEM GOT IT'S OIL CHECKED THAT MORNING OR DAY BEFORE AND SHOWED UP MAX. THOSE NEW ENGINES HAVE ELECTRICAL OIL READER (NO STICK ANYMORE) SO I HAVE TO RELY ON THAT. I AM HEAVILY DISAPPOINTED IN BMW AND HOW THEY ARE HANDLING THIS ISSUE. THEY SHOULD OFFER REMEDY AND FULL REIMBURSEMENT OR RECALL FOR THIS WELL KNOWN PROBLEM. *TR
