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.
The contact owns a 2020 bmw 330i. The contact stated that the headlight housings would become foggy whenever it rained. The contact stated that the failure had caused the low beam lights to be diffused and to fail to illuminate the roadway beyond 15-30 feet. The vehicle was taken to the dealer with photos of the foggy headlight housings, but the dealer informed the contact that they could not replicate the failure because the headlight housings were clear the time. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 34,000.
The lower active grill on my 2020 bmw 330i failed. I purchased the vehicle on january 24th. On february 27th, the check engine light came on. I called the dealership i bought it from. They told me they did not have the necessary technology to diagnose, so i took it to a bmw mechanic. The mechanic told me it is a known warranty issue with this particular bmw, and that bmw should fix it for free under the limited warranty bulletin. When i tried to contact bmw about this issue, they refused to pay for it stating that my specific vin number was not affected by this issue, and therefore they wouldn't pay for it. This makes no sense seeing as it is a clearly known issue with an active bulletin out for the same exact year make and model as my vehicle. The production clearly did not change enough to fix the issue, so my vehicle should be included in the limited warranty/recall. The flaps can get stuck closed, which can cause the car to overheat quickly, which can be extremely unsafe. Bmw refused to even look at the vehicle to see if the issue was in fact the warranty issue without me paying a $250 diagnostic fee, when i had just paid to have it diagnosed at a different bmw mechanic.
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
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
A check engine light or check control message is present, and one or more of the following faults may be stored for the active air flaps behind the kidney grills. This is a known issue with other models. (si b17 06 18)
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.
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?
