The oil filter housing on my BMW 330i failed randomly while driving causing my vehicle to be depleted off coolant within seconds. If you want to inspect the part you will have to reach out to BMW of columbus for documentation and I can provide the service records for repair. This caused my vehicle to have to be brought to an immediate halt to not cause overheating or engine destroying failure at a time where service/repair isn’t available. There were no warning lights or leaks prior to the vehicle malfunctioning all at once. I ubered to get coolant and once filling the reservoir the coolant immediately leaked out resulting in me needing a tow to the dealership. This problem has been reproduced with many dealers as there’s numerous of report of this online and I believe the dealer has inspected this part but is refusing to replace or recall this part under any type of program or create any type of solution to make this not happen again. There wasn’t any small leaks or warning lights shown before this issue spawned all at once then showing the low coolant light.
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.
Multiple codes came on right after I had gotten my thermostat and my water pump fixed. However it ended up being that there was more leaks throughout the rest of the car. The car has currently cost me $3400 to fix and it’s still not fixed because nobody can figure out where the actual leak is coming from. The coolant is leaking and nobody can figure out where, it’s been having jerking issues since it started leaking and I read on other BMW’s that the coolant leaks into the head gasket, causing the engine to blow.

At around 65k miles multiple plastic engine coolant connectors and hoses crack and fail. 5 locations at the same time! coolant pump leaks. I went to an independent repair shop for a second opinion and repairs for $2,400 so far. Cheaper than the BMW service department. There was a recall done 2 years ago for 1 hose I believe. The entire cooling system should be recalled. We could be stranded somewhere in a bad situation and the engine could be destroyed if overheated. Awful and bad design.
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.
My oil filter housing failed at about 53,000 miles. While driving to work I got a low coolant warning and pulled over to see coolant dumping out of my car. The low coolant warning only comes on when the expansion tank is almost completely empty which can lead to oil and coolant mixing and overheating which will lead to premature engine damage without any early warning signs. I’ve read through forums and everyone on there has their oil filter housing fail at the same time, (around 50-60k miles). This is a huge issue in the community and BMW wants to charge almost 3,500 to replace it with their “revised part”. The housing has been revised 3 times now and so the manufacturer should replace these failed designs with the new revised ones. There’s already been a recall on the b48 engine for the plastic cooling line that leads into the head of the engine and it looks like the oil filter housing is the next biggest common failure. I tried to upload a screenshot from the service center at BMW with the quote and failure but it’s not working on my mobile.
My 2019 BMW 330i has a recurring cooling system defect, including coolant leaks, heater inoperative, and risk of engine overheating. The defect began while the vehicle was under warranty and was repaired by BMW, but it recurred. BMW later instructed me not to drive the vehicle due to safety concerns, yet declined responsibility and transportation. The vehicle remains unsafe to operate.

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.
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 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.
Both the upper and lower active grille shutters for most BMW models in the 5 model years prior to mine had extended service warranties due to frequent failures of the part. It appears that the design was not improved with my model year and yet my vehicle is not part of the extended warranty. My vehicle is only 4 years old and both the upper and lower air flap control motors have failed. The motors are not sold individually, but are sold as a part of the entire shutter assembly which has a part cost of $250 - $350 each with comparable installation costs. The lower shutter assembly requires the removal of the entire bumper. Why is the extended service warranty not applicable to newer models?.

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.

BMW has issued a recall with no resolution. My engine is making noises from the crankcase and no alternative has been offered at this moment. The dealer does not want to address the issue.
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 im 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 wba8b9g36hnu54119 for all incident reports with this vehicle.

Engine wiring is made of soy products with attracts rodents to feed and destroy the wiring. When this occurs it puts the driver ad passengers in danger because certain functions such as brake light, headlights and windshield wipers may not work properly. This is becasue when the wiring is compromised , circuits are broken which causes the vehicle's systems connected to that circuit to partially or completely fail, rending a vehicle partially or completely inoperable. The vehicle was inspected the the BMW dealership service center and they confirmed it was rodent damage . Geico insurance also inspected the vehicle. The vehicle started to restrict engine performance and the engine service light came on stating there was a drive tran malfunction.

On January 19, 2022 I was driving and then smoked filled inside my car and the outside engine was smoking and a light came on that said check coolant. BMW service took me in that day and they said my coolant broke. They removed it and replaced it. They did not understand how the coolant broke but I paid for the service and parts and moved forward. On November 25, 2022 I went into the same BMW service center to get a routine car service and they stated there was a recall and they would replace my coolant for free. (after I told them I paid for it ($699. 63) . They insisted I replace it for free again and reach out to BMW corporate for a reimbursement of previous service. I received a call yesterday stating they would not replace it and reach out and file a report with nhta.

I didn't get any pictures. My sister has a 330 xi drive to denver at one point of the drive hurdle a pop in the car. Where driving fast no pot holes hit. After further investigation with a mechanic friend of mine. We got under the car the car and noticed the passenger side axel was resting on the frame of the car. There where 3 motor mount bolts sheared off the motor mount brackets an 1 laying on the scid plate under the car. I have read some other testimony about this problem on the internet. I believe this could be a definite problem so I hope you look in to this problem thank you.
