In November of 2023 I was driving my vehicle on the highway when my vehicle's control panel notified me the engine was over heating and I needed to stop driving the vehicle immediately. All the engine coolant had leaked from my vehicle. I had to pull over on the highway and have my vehicle towed. My mechanic identified the problem as the coolant vent line and made the repair. Total cost was $2,052.16 including the tow. A few months later a message from BMW came up on my vehicle's computer display saying there was an "Important recall or campaign", a service action for the exact repair I paid $2,052.16. They now refuse to reimburse me because it is not labeled a "recall". This issue is widespread and needs to be labeled a recall for consumers. A known defect since 2022 that I was never notified prior to the incident and now they refuse to reimburse me for a know defect in their product. I believe this violates my rights under federal consumer protection laws. Please help the consumers and force BMW to label this safety issue a recall and stop hiding behind their euphemisms

Persistent Low coolant warning issue, Coolant leak was discovered to be coming from Oil filter housing. This is a $3000 repair on something that should last at least as long as the engine. If there are others with this problem, Then maybe a recall is due. Dealer is repairing now at my expense.
BMW B48 engine. Coolant started leaking and the engine overheated. Unbeknownst to me caus the bottom of the car is covered. I had a mechanic look at it. Found the leak coming from the "oil filter housing unit". When he removed it it was broken at one of the 6 ports inside with the pieces missing presumably fell into the interior of the engine. BMW manufactured these units out of a composite material and not aluminum I assume to save costs and weight. This composite material has failed in many of their engines including the mini cooper. When I looked on line googling it I was shocked at how wide spread it was. It's a costly repair about 2000-2500 for parts and labor. This composite material is also used in their failing water pumps all the failing coolant hose connectors and more I believe.
The plastic oil filter housing assembly developed a crack as we all should know heat and plastic do not do well with each other. Cause my coolant at first to slowly leaked and never gave me a warning of low coolant. Driving 60+ mph then all of a sudden cars goes into limp mode so the person behind me lucky swerved to the left to avoid hitting me. So filled up coolant and same thing happens again about a week later. No visible leaks no dashboard warning of low coolant levels. So I fill up and go. Mind you my engine is already overheating when it tells me on dashboard while going into limp mode at the same time so continuously overheating engine seems to cause more problems water pumps starts leaking and pipes start developing holes. Safety comes into play while driving down a highway when car goes into limp mode causing the driving that’s not paying attention ram into you. Quite a few safety concerns. Never had a chance or opportunity to pull over to self diagnose, car goes into limp mode with no warning. There are several thousands of this reporting the same with oil filter housing assembly. As I am writing this my mechanic is in the process of taking the part off and replacing it with a metal one. This first happened around thanksgiving 2023 and progressively got worse with each week
Coolant Leak from oil filter housing caused a major repair. The Car has about 109,000 miles. Parked it after work on a Thursday went to drive it to a family dinner Friday, i turned the car on and immediately get a low coolant light. I drove 2 miles down the road, Suddenly the coolant started pouring out and the coolant light comes on again, i return home and have to take my girlfriends car. On the invoice it states, “entire oil filter housing part was replaced”, the plastic used to seal in the coolant had either been destroyed or broken off, not a gasket but a piece from the oil filter housing part. The dealer charged $4500 for the repairs, which they said were “optional” but the engine couldn’t hold coolant. This item is not on the recommended service list, as it’s not an item listed for “wear and tear” However the B48/58 engines are so new that finding enough over 100K miles is not easy to replicate the issue, although message boards have recently discovered this issue occurring with more regularity. Please investigate and help consumers who potentially could be left stranded by this defect.
Coolant Leak caused a major repair. The Car has about 90,000 miles. Suddenly the coolant started pouring out. As you see in the attached invoice, entire heat exchanger, water pump, and other several parts were to be replaced. The dealer first estimated the repairs at $5,400 and they agreed to do it at warranty price rates. However, we believe other BMW models have had similar recalls for Coolant leak and suspect same on this model too. Please investigate and help consumers who are ending up paying exorbitant amounts to service shops. BMW may be hiding this problem from NTSB to avoid recalls by agreeing to repair at vehicle warranty rates.
out of nowhere with only 1 day warning car requested coolant refill. After refill within 10 minutes car engine ran hot and completely stopped on the expressway. I’ve read hundreds of reviews online and youtube where this exact same thing has happened to others with this same car.

When I was driving on suburban roads with speed limit of 45 mph, I received a waring from my vehicle saying "engine high temperature, drive moderately". After sometime, it said "engine overheated stop carefully". During the first warning, I felt loss of acceleration power and during the second warning I felt completely no power in acceleration that too when I was yielding for a left turn which was life threatening, luckily the oncoming traffic slowed down. Otherwise I would have ended up in life threatening crash. During both warnings, I checked the engine temperature gauge in the instrument cluster and the engine temperature was not even 50% of the maximum temperature in the gauge. After the warning, I slowly made it to a nearby parking lot and opened the hood and did not physically feel any excessive heat for an engine not to function. I regularly service my vehicle and my vehicle is not due for any kind of service for the next 2000 mile as per the onboard vehicle status. The next day I started the vehicle to help it to climb the tow truck ramp and at that time, for the very first time I received a warning saying engine coolant is very low. I have never received this warning since I have owned the car until then. I have two concerns, 1. The temperature gauge did not show a high temperature, only 24 hours after the electronic engine high heat notification, the low coolant warning came in which is weird and my vehicle isn't due for any service. 2. None of the above should result in a sudden loss of acceleration power which could have resulted in a fatal crash in my case. I'm a mechanical engineer with a strong background in automotive occupant safety (airbags/seatbelts) and that's why I see this a very serious incident that needs to be looked into so that it doesn't occur for anyone else in the future.
Water pump keeps going bad 2nd time replacing in 2 years rough idle and failed part problems that BMW service team does not understand. Vehicle has stalled at 0 rpm I'm thinking there is an issue with the engine also reported by previous owner and I also have the same complaints, as well the foot release which I was was told was an option never worked. Please search vin [XXX] for all incident reports with this vehicle. INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).
Everytime I start up the engine, the idle is in high RPM like 1200-1300rpm even it is warmed and then gradually goes back to normal after a minute. And in cold start there is a loud thud sound under the car and seems like the car engage and then disengage, only in cold start.
Water pump had to be replaced. However, liquid from the water pump caused the filer to be damaged and results in a fire smell throughout the care.
