   The defect has left the driver stranded several times and required multiple tows due to the vehicle becoming unsafe and inoperable. On one occasion, the vehicle broke down after a 2.5-hour drive away from home and had to be towed because the overheating and coolant leak issue made it unsafe to continue driving. The vehicle is operated in a region where summer temperatures frequently exceed 115°F, which significantly increases the safety risk associated with repeated overheating and roadside disablement. The issue remains unresolved and continues to pose an ongoing safety risk due to sudden overheating and loss of reliable vehicle operation. There are multiple dates started mid 2023 through today 4-6-2026 , still overheating after failed attempts

   The cooling system is continually failing prematurely. Parts that should be lifetime are needing to be repaired below 100K miles. I have had to repair the following cooling system related items that should be under recall and are not Oil filter housing Thermostat housing Turbo coolant lines Water neck the cost of repairs is significant and BMW is denying responsibility for the premature failures.

   The Oil Filter Housing (OFH), the Coolant/Water Pump, and other plastic lines for the cooling systems are well known to fail with this engine early in their lifetime. My service advisor at BMW said, "these are very common issues for a B46 engine.". The Motor Mounts also are extremely prone to failure due to the use of the Auto Start/Stop feature. This has also been noted by my service advisor at BMW. They commented, "these cars come in often before ever hitting 20k miles and needing replacement. I recommend never using the Auto Start/Stop feature ever again.'

   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.

    2 low coolant warnings within 4 months ended up being an oil filter housing failure, leading to oil and coolant mixing and leaking. This failure could have lead to catastrophic engine damage. An ASE certified shop is doing the repair for around $2,950.

    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

    There is a well known issue with the clip on BMW 3 series (mine is a 2017 330i) that holds the parking brake cable assembly to the body if the car above the drive shaft towards the rear of the car. The plastic clips fail frequently, causing the parking brake cable assembly to fall and the brake lines rub against the driveshaft creating a metal-to-metal noise. Over time the friction between the drive shaft and parking brake cable will eventually create failure of the cable in my opinion. I have this issue and I have seen several online videos of others who have the same issue.

    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.

    In October of 2023. I notice low coolant notification came on screen. checked coolant saw it was low. Added Coolants. 3 days later same notification. Took vehicle to Shop who stated the coolant cap seal was broken, so I had them replace the coolant cap. 3 days later the same Low coolant light came back. Every few days I had to put coolant in my vehicle. I went through 2 bottles of coolant. Over the Christmas holiday Dec/2023. I dropped my vehicle off at a shop. The oil filter housing and cooler gaskets was bad. BMW replaced this piece from a metal part with a plastic piece. This is my only vehicle and I had to pay for this expensive repair so I could get back and forth to work. Prior to me having the repair done, when I was trying to figure out the problem. I noticed a lot of online information of the same issues for 2017 BMW 330I. THe shop . did the repair told me he had done about 10 of these repairs for the same Year/Make and Model.,the past few months. I had to pay $2,637.20 for this repair. There is clearly a notable problem with coolant leaks. I make sure I have vehicle serviced when the notifications come on the screen and have documentation to show this. Please look into this issues.

    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
