Engine And Engine Cooling Problems of BMW M5

BMW issued a stop sale on 2017-2023 BMW f90 M5 chassis regarding the expansion tank failure. All vehicles should be affected by the recall. My current vehicle is experiencing the issues stated on the recall notice. Expansion tank is failing and causing coolant to seep into engine bay.

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.

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.

Coolant expansion tank is leaking on fuel injectors, coils and plugs on engine below causing ‘drivetrain malfunction’ which puts vehicle into limp mode. Car can begin to shudder, misfire and stall. BMW has an sib on the expansion tank, but has done nothing to address the components underneath that get damaged. Feel free to google BMW M5 coolant expansion tank issues.

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.

The coolant tank on my 2018 M5 failed causing a coolant leak. This is a highly documented problem on the forums and mine needed replacement at 22k miles. The bigger issue is the location of the tank because the coolant leaks on the ignition coils and fuel injectors causing failures later. My coils and spark plugs needed replacement along with the tank. This is unacceptable and BMW needs to address this issue.

My car (a 2014 BMW M5 with only approx. 39k miles) has a known issue with defective fuel injectors (manufactured by bosch, subsequently replaced by an upgraded part). In fact, in 2018 BMW issued me and other owners with an extended warranty for the fuel injectors for 10 years/120,000 miles (see attached copy). However, in my opinion and based on a 9/7/2022 failure incident I experienced the defective fuel injectors should have resulted in a safety recall. Previously, my car experienced a check engine light in August 2022. The dealership suspected one or more leaking fuel injectors and noted as such on my repair invoice, but I was told due to the testing protocol which BMW requires they could not replace any of the fuel injectors. BMW's testing protocol also resulted in me incurring a large bill of almost $1,100 due to the diagnosis labor involved. On 9/7/2022 while I was driving on the highway at approximately 70 miles an hour, 2 fuel injectors failed (out of 8 injectors, confirmed by subsequent repair) which resulted in a sudden and complete loss of engine power while maneuvering in traffic. I am extremely lucky the sudden loss of engine power did not result in an accident, and I was able to take a highway exit using the vehicle's momentum. Upon exiting the highway, my car's engine completely died and would not re-start. This resulted in my car obstructing the road where it almost caused several accidents and necessitated a 911 call by me to obtain police assistance to get my vehicle out of the way. After this frightening experience and due to the high failure rate I already experienced with 2 out of 8 injectors, I contacted BMW customer service and attempted to get the remaining 6 injectors replaced. BMW refuses to replace the remaining injectors and stated they would only replace a specific injector after failure. I urge the NHTSA to require BMW to perform a safety related recall for this known fuel injector issue.

Behavior of my car's dct transmission has created a dangerous situation which almost resulted in an accident for me. I believe this is due to a software change BMW made to the dct transmission. The issue is as follows: -when driving at highway speed, when you release the throttle and let the vehicle coast (as when you want the vehicle to naturally decelerate without braking) the transmission will disengage the dct clutches. The car will then maintain speed (as if cruise control were engaged) instead of naturally decelerating. In and of itself, this behavior is dangerous due to the fact the vehicle will maintain unwanted speed. -when then trying to re-accelerate quickly from coasting where a downshift is needed (as in when needing to pass legally on a 2 lane highway), the car will not re-engage the clutches for a couple of seconds or so. This causes total loss of power or acceleration for 2 or so seconds. While this may seem like a relatively minor situation, the above situation almost caused a serious accident at highway speed. Also, my car did not previously display this behavior until after a service visit (I believe last year). I suspect the dct transmission software was updated by BMW without my knowledge and is the source of this change in vehicle behavior.

Clearance failure on s85 engine to rod bearings causes oil starvation. This in turn causes engine catastrophic failure. If driving this will effect power breaking, power steering and all components requiring the engine to be running. This is a very common issue, I now have symptoms requiring a change of rod bearings.

My family and I were heading home on the freeway and the cars engine light came on and the engine went into limp home mode along with a loud knocking from the engine. The next day I had to car towed to BMW of honolulu. The dealership contacted me and told me that I needed a engine which they quoted me a price of $35k for a new engine. I then called getzinger motorwerkes which is another shop that works on BMW's just to get a second opinion. After diagnosing my car the owner of the shop told me that it was crank bearings and since they went bad the medal shaving went into my engine and also caused the vanos pump to go bad, he then stated that he was just reading about that same issue that has been happening with a lot of 2006 M5;s due to the fact that its a bad engine design and that those parts would go bad every 60,000 miles. To replace those parts it would cost $8,000 in parts alone. So now I am stuck paying for a car that I can't even drive. I now live in another state and my car is stuck in hawaii because the shipping company will not ship it in the condition that its in.

Enroute from palo alto to mountain view and was at a complete stop waiting at a stop light on a major thoroughfare (central expressway) when the car stopped running. Cars behind me proceeded to pass me to make the left turn while my car was shut down. I was able to re-start the car after ~5 - 10 minutes and drive another 1000 feet when the car stopped running again. Prior to both incidents the panel indicated an alert "transmission fail" and a "check engine" alert. The car would not start back up and had to be pushed through the intersection to a street where it could be parked safely. Initial autobody electronic diagnosis and repairs related to battery replacement, however, transmission related fault codes still showed up. Fortes brothers autobody discovered "safety" related notifications issued by BMW and therefore recommended taking car to BMW. Car was then towed to BMW mountain view dealership where service department diagnosed and then replaced both hydraulic pump and clutch. Based on subsequent research on the internet, there are references to hydraulic pump recalls by BMW for BMW M5 2005 model. Although my car is a BMW M5 2006 I am requesting follow up to confirm that the hydraulic pump is manufactured to all required specifications and does not pose a safety risk.

After taking my car to the dealership several time complaining about idling and engine knocking. I was told it was the gas, and the change of weather causing the problem. They finally supposedly replaced the parts in the engine, but I still had the problem later, and my neighbor notice it as well. While driving my car started smoking and the oil spill to the highway. After having the car examined, I was told that the bearing on the rod was loosed and had caused the rod to break and tore the engine apart. I contacted the costumer relation of BMW headquarter and they gave me every excuse why they couldn't do anything. I was advised by the shop this was a manufacturer defect and it could've been avoided by the dealership, etc. I need advice and I am considering getting legal advice. I refuse to pay $25k for another engine on a car that caused me $100k and engine blown so quickly. BMW knows that this a problem and refused to correct it. ## VIN passed ## BMW, M5, 2006 ##.
