Despite following the manufacturer’s recommended maintenance schedule and having the car serviced at authorized BMW dealerships, I am facing an engine failure that BMW has quoted $44,000 to repair. BMW is only offering $4,000 towards this repair, leaving us with an overwhelming out-of-pocket expense. My insurance provider has informed me that they will not cover the cost of these repairs, placing us in a difficult financial position. Given the extensive history of issues and consistent maintenance of the vehicle, this situation is both unexpected and unacceptable. The car was even under the factory warranty when many of these issues were first reported. The vehicle has a documented history of engine-related issues, which are as follows: 1. February 25, 2023: The car exhibited a drivetrain malfunction warning and check engine light. The diagnosis revealed an issue with cylinder 6 fuel injector, which had an internal electrical fault. The fuel injector was replaced, and the problem was temporarily resolved. 2. February 27, 2023: Another drivetrain malfunction warning occurred. The diagnosis showed a misfire in cylinder 6 due to a faulty ignition coil and spark plug. Both the ignition coil and spark plug were replaced. 3. May 12, 2023: The car experienced a drivetrain malfunction and reduced engine alert. The diagnosis indicated multiple issues, including the need to replace the fuel injector, and perform service on the spark plugs, brake pads, and other components. 4. June 7, 2024: The vehicle made an abnormal clicking noise when idle, and there were complaints about the wobble at highway speeds.

The coolant reservoir tank leaks causing coolant to destroy the injectors on the engine below below which later causes engine failure. Nearly every BMW M5 owner I know has this issue. My coolant tank has been replaced twice in total 30,000 miles. BMW continues to provide faulty tanks. The last replacement was less than 1200 miles ago and the new tank is already leaking.

I actively participate in online F90 forums, and it seems like the coolant expansion tank seems to fail for almost all owners (both pre-LCI and LCI). In many cases, it also damages critical engine components underneath the tank and results in expensive repairs. Indeed, because BMW has failed to address this problem, the afternmarket already offers an aluminum billet coolant expansion tank, as well as a coolant expansion catch can that reroutes escaping coolant so as not to damage components located beneath the tank. While interacting with other owners, I learned that these failures continue to fail (including the recently revised part number) and there are several owners that needed the tank replaced multiple times (an owner I interacted with on bimmerpost today is on tank #8). Can you please advise as to BMW’s intent to properly and permanently fix this issue? It's a major design flaw impacting all F90 M5s (ticking time bomb), and I am very surprised to see no official recall and replacement part that properly fixes this critical issue. This issue is not about an individual vehicle, but a manufacturing defect that impacts all F90 M5s. Please share this message with the team responsible for supporting the M5 product and request that they respond on how they are planning to permanently fix this issue. Please understand that this is a serious concern shared by dozens of M5 owners I am in communication with. Waiting for the failure to happen on a given F90 M5 and going to a service center is NOT a viable option since it may already be too late and the damage already done. My car has documentation that proves the coolant expansion tank has failed previously at around 12K miles and affected other parts such as injectors. After less than two weeks of owning the car, the coolant tank has failed again as evidenced by coolant escaping at the tank seam. The car now has slightly over 14K miles.

Engine coil and fuel injectors are bad. Injector 8 went bad, followed by 6&7. The next just went bad. Was told only so many available at dealership because of on going problems.

The contact owns a 2019 BMW M5. The contact stated that while driving at an undisclosed speed, the vehicle stalled. The check engine warning light was illuminated. The vehicle was towed. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The contact researched the failure and related the failure to an unknown recall. The contact also stated that the vehicle had been repaired prior to owning the vehicle for coolant leaking into the engine. The manufacturer was made aware of the failure and confirmed that the vehicle was not included in the unknown recall. The contact was advised to contact the NHTSA Hotline for assistance. The failure mileage was 47,859.

Coolant bottles on all F90 BMW M5's have a faulty coolant bottle that BMW refuses to acknowledge. The coolant bottle cracks no matter how many times it's replaced and it leaks coolant down into the injectors causing injector and engine failure.
