Plastic oil filter housing part cracked and leaked all my anti freeze out on I 95. This incident caused me to have my car towed 3 times to various dealer and shops for repair. Total cost of this repair was approximately 2K with parts and labor + 300. for towing. No warning from BMW - this could have caused myself and others great harm out there on 95 and if I had to drive farther to find a safe place to pull over it would have destroyed my engine.

Consisent failure of coolant line system. First noticed warning light "low coolant" and immediate overheating in November of 2021. Had the issue repaired at mechanic in 11/2021. Then same exact issue recurred in April of 2023, starting with warning light of "low coolant." Received letter from BMW USA indicating the problem can be repaired at any authorized dealership, but that this was NOT a recall. Took my car to authorized BMW dealership and got the same problem repaired. Just had the same exact thing happen again, same warning light, and took back to same authorized dealership to check the repair and was told multiple issues with the coolant line and had to pay $1900 for the repair. I am being told by several mechanics that this a design defect/flaw in these models of 4-series BMWs from 2015-2019 years. I am being warned that this issue will likely recur in the next 6-8 months.

Oil filter housing and coolant leak from same housing. While driving, safety warning light came on and car began to overheat. Per several mechanics, this is a known issue with BMW Series 4 from redesign in car after 2017. Redesign implemented plastic housing which cracks and leaks. Same issue also listed as problem when researching on internet (hundreds of listings). Housing and seal cost $574 in parts but labor cost $2199.40 due to location of repair. My car had 55,000 miles on it and is housed in a garage.
