Engine & cooling

Diesel fuel pump failed while driving on the road. I also own a 2014 328d BMW which was recalled earlier where the diesel fuel pump was replaced by the dealership. While driving on the road, the car unexpectedly turned off in traffic. I managed to get the vehicle off the road and called a tow truck. I contacted my local BMW dealer and informed me my 2017 328d is not under a recall like my 2014 328d was. I then instructed the tow truck driver to take the car to an independent mechanic who specializes on BMWs. The diagnosis is a fail fuel pump.

Component: Engine Cooling System: Turbocharger Coolant Return Line/Fitting (Part # 11538854735). Defect Summary: The factory turbocharger coolant return line on the B48 engine uses a plastic quick-disconnect fitting and O-ring mechanism positioned directly under the turbo. Extreme thermal cycling causes this plastic to degrade, become brittle, and fail or separate without warning, resulting in immediate, catastrophic drainage of pressurized engine coolant. Failure of Manufacturer Requirements: This component fails...

basic durability, material safety, and engineering standards for pressurized cooling systems. The design is so fundamentally flawed that authorized factory-trained technicians cannot permanently remedy it using OEM parts; the connection mechanism fails to maintain a pressurized seal under standard operational heat. Freeway Safety Incident: While traveling at high speeds in high-velocity freeway traffic, the fitting failed catastrophically without warning. The sudden coolant loss forced an immediate engine stall/power failure in active lanes. Navigating the powerless vehicle out of the middle of the freeway while surrounding traffic swerved nearly caused a severe, high-speed multi-vehicle collision. Inadequate Remedy & Recurrence: The vehicle was taken to an authorized dealership (BMW of the Woodlands, TX) for repair. However, within one week of dealership service, the new OEM line/O-ring completely disconnected again. This recurring separation completely drains the coolant within days, causing subsequent engine stalls, rendering the car undrivable, and repeatedly placing occupants in extreme danger. Thermal & Fire Hazard: Each failure sprays pressurized coolant onto a hot turbocharger and exhaust manifold, creating immediate risks of blinding smoke, vision obscuration, and engine bay ignition, compounded by thermal risks to the 330e hybrid powertrain battery electronics.

Hybrid battery has a failed cell. It was confirmed by BMW diagnostics but BMW refused to repair/replace failed cell even though it was under full 8yr/80k mile warranty. BMW claimed it as wear and tear, even though 1 out of 5 cells completely failed. The failure caused the car to run at reduced speeds causing others cars around me on the freeway to be in danger as all of sudden I am unable to reach freeway speeds due to part failure. There was an error stored in the car per BMW diagnostics that called for failed...

My BMW has had multiple repairs (3 incidents - 2 times repaired by BMW and 1 time repaired by a national mechanic garage) to the coolant system since I purchased it in 2018. BMW have verified the leaking coolant as well as the independent garage. Currently, the coolant system has another on going issue where it is still leaking and it's still unable to be fixed. This coolant issue has had catastrophic failures at times and more recently it has thrown a major engine overheating warning that has impacted the safety...

of my wife, kids and I as well as other individuals on the road as I have had to pull over quickly and turn the car off to allow the engine to cool down. I've had to drive the car at a reduce speed and acceleration which has frustrated many drivers causing them to over take me dangerously. Additionally, I've burnt my hand from opening the coolant expansion tank to add coolant on multiple occasions.

UNKNOWN, it has problems with stalling and starting up could be issues with the internal drive system that I've seen other types of similar models of bmw having these recall issues as well. When starting up after fueling up it over exerts the engine trying to start up. You kind of have to rev it to start it up. And driving it after that it has trouble keeping a solid drive.

The vehicle had a recall on the engine coolant valve line which was taken care of by BMW dealership on November 1, 2024. In less than a month later, an issue has been noted of coolant leak which caused the engine to overheat causing a safety issue on the road while driving my kids to school. The service manager advised that the issue is not part of the open recall that was already done on November 1st. How can a recall for the same concern of coolant leak and engine over heat cover only one hose where the issue could be related to another hose connection?

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

I'm not sure why my car was not apart of this water pump recall. I was driving without any warning my car started stalling and then completely stopped on me. I had to pay for a new water pump due to this. I thought that was was strange as I have always be up on all maintenance for my car. My car was in top notch condition and this occurred from no where. Thank God I was not hit.; but this did cause me a lot of hassle and money. I am asking BMW to refund me for my time lost and money spent. My car should be among BMW recall. Please add this car model to the recall and refund me my money.

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...

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

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.
