The contact owns a 2012 BMW 528XI. The contact stated that while driving at an undisclosed speed, the vehicle came to a stop and the Automatic START/STOP feature activated; however, the engine failed to restart. The message "Drive Train Malfunction Error" was displayed. The vehicle was towed to the dealer, who determined that the timing chain had fractured, causing unknown parts to enter the engine. The contact was informed that the timing chain needed to be replaced. The vehicle was not repaired. The contact associated the failure with the federal safety agency Campaign Number: 23V707000 (Engine and Engine Cooling); however, the VIN was not included in the recall.

I am submitting this report to notify the federal safety agency 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 the federal safety agency 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)

The vehicle suffered a sudden Drivetrain Malfunction and severe engine overheating while driving, resulting in a physically snapped camshaft and extensive iron shaving contamination in the oil pan (catastrophic engine failure).Ten months ago, an authorized dealership performed the official BMW Water Pump Safety Recall (the federal safety agency Campaign 24V608000). The vehicle has an active history of drivetrain malfunction fault codes dating back to January 2024. The failure of the recall remedy to safely maintain the cooling loop directly caused severe thermal stress and lubrication breakdown, leading to the camshaft fracturing. Additionally, this engine was under the VANOS Bolt Safety Recall (the federal safety agency Campaign 23V707000), which covers loosening valvetrain bolts known to break camshafts.This is a direct consequential safety failure resulting from defective recall components, causing sudden engine failure while operating on a public roadway. Vehicle is currently held at Fields BMW awaiting corporate inspection.

The contact owns a 2012 BMW 528XI. The contact stated that while driving at various speeds, there was a misfire coming from the engine with the "Drivetrain Malfunction" message displayed. The contact later received a notification for an unknown recall, and a diagnostic test was performed however, no failure was found for the drivetrain. The recall repair was performed. Recently, the contact stated that the vehicle would shut off soon after it was started. The vehicle was taken to an independent mechanic where a diagnostic was performed; the diagnostic test discovered that the camshaft sensor was fractured, and metal shavings were found in the oil pan. The vehicle was then diagnosed with engine failure. The manufacturer was notified of the failure. The vehicle was not repaired. The failure mileage was approximately 128,900

Engine failure due to faulty timing chain or oil pump while driving

Filed Sep 2, 2023 · Engine, Transmission · PA

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.

On March 24, 2022 I bought a 2008 BMW 528XI vehicle from Mercedes WESTWOOD, MA. UNFORTUNATELY, this car is not drivable because it needs a new transmission. It hasn't even been a year yet. The check engine light came on after the second day of purchase . Now I needed a new engine. Mercedes of WESTWOOD MA sold me faulty car (LEMON).

While driving my car at about 30 miles per hour the engine suddenly seized up. There was no warning at all. I had it towed to the dealer, Baron BMW in Merriam Kansas. After evaluating the car they determined the engine failed and it was an issue of lack of oil. I had taken the car to this dealer prior to buying the car to make sure there were no problems. After their inspection I went ahead and bought the car. It had 40,528 miles. I had taken it to the same dealer for service for 3 years prior to the engine failure When the engine failed the mileage was 95,444. I talked with the dealer and let them know that I felt BMW should pay for replacement of the engine. They refused to do this so I was stuck with having to pay for another engine. After researching this issue I found out that there numerous issues with the engine and that several people had had the same problem. BMW was aware of this issue and chose not to do a recall as they should have . Instead the went ahead and made the decision to not do the recall and deal with the engine failures when the engines failed . This would be less expensive to do rather than do the recall which they should have done. So what they did was to sell the 528i model and let people drive the cars , knowing that a certain number of cars engines would fail. Since your organization is concerned about safety issues ,shouldn't you have taken some action once you became aware of the engine failure issue I would hope you could consider some kind of fine or whatever against BMW for putting a car out on the road knowing a certain number of engines would fail while people were driving . They were more concerned with profits rather than the safety of the public that would be driving their cars. While you are at it it would be good if you could fine BMW and have them reimburse the owners of these cars in which the engines failed! Thank you for your time and consideration.

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!!
