BMW class action lawsuit overview:
- Who: Three consumers filed a class action lawsuit against BMW AG and BMW of North America LLC.
- Why: The plaintiffs claim certain model year 2014-2021 BMW and MINI vehicles were equipped with a defective engine oil filter housing.
- Where: The class action lawsuit was filed in New Jersey federal court.
A new class action lawsuit alleges BMW sold certain model year 2014-2021 BMW vehicles and MINI vehicles, including the Mini Cooper, with a defective engine oil filter housing.
Plaintiffs Aaron Eiger, Kendra Cherry and Kelly Haley Fucillo claim the engine oil filter housing for the engines of the affected vehicles often fails at less than 50% of their reasonably expected useful life.
BMW and MINI vehicles sold with the allegedly defective engine oil filter housing include model year 2014-2021 1 Series, 2 Series, 3 Series, 4 Series, 5 Series, X1, X2, X3, X4, MINI Cooper, Clubman and Countryman vehicles equipped with B46, B48 and/or B58 engines, according to the BMW class action.
Eiger, Cherry and Fucillo want to represent a nationwide class, Illinois class, North Carolina class and California class of all owners and former owners, lessees and former lessees of class vehicles who purchased or leased their vehicles.
Premature engine oil filter housing failure cost vehicle owners, class action says
Eiger, Cherry and Fucillo argue the allegedly premature failure of the engine oil filter housing cost vehicle owners between $2,000 and upwards of $3,000 to repair, depending on the class vehicle.
“Individuals who own or have owned class vehicles also sustained diminution of the resale of their class vehicles since knowledge of problems with class engines became public information,” the BMW class action says.
Eiger, Cherry and Fucillo claim BMW is guilty of unjust enrichment, in breach of two uniform commercial codes, and in violation of the Illinois Consumer Fraud and Deceptive Business Practices Act, North Carolina Consumer Fraud and Deceptive Business Practices Act and California’s Unfair Competition Law.
The plaintiffs demand a jury trial and request declaratory and injunctive relief and an award of actual, compensatory and/or statutory damages for themselves and all class members.
Last year, a group of BMW drivers filed a separate class action lawsuit against the automaker last year over claims it sold certain vehicles with defective transfer cases.

I have a 2015 mini cooper with the b38 motor that experienced this failure. It only had around 50k miles and the coolant was mysteriously disappearing. After a shop visit, the mechanic confirmed it was the oil filter housing and quoted us over $2k to repair due to the difficulty of the job. I also own a 2020 BMW m340i which has the b58 motor and they too experience the same issue due to cheap plastic housings that warp and break from the repeated heating and cooling. This should be a recall job and replaced for free by BMW. Either that or pay me the money to have the job performed
We have a 2016 Mini with the B46A20 engine that also experienced premature OFH (oil filter housing) failure. The first sign of trouble was slight coolant leakage @ 101974mi that dripped down & collected on the oil pan along with 1-3 pints of coolant that would “disappear” from the reservoir.
Removal of the glass-nylon style OEM OFH revealed a crack at the coolant passages that expanded through the o-ring sealing area. This crack appeared to progress until a 10-12mm sized chuck broke off internally at the coolant passage. The failure of my OFH seems to be consistent with other pictures I’ve seen of B4XX related OFH failures. At this time, the plastic OEM coolant pipe-to block fitting, commonly called the “mickey mouse” flange was also noted to be degraded and replaced with an aftermarket aluminum part.
The cracked OFH was replaced with a new aluminum bodied part of aftermarket design as I was unable to procure an OFH from BMW at the time. New OEM gaskets & bolts were used to reinstall the new OFH. All BMW specific torque procedures were followed during reinstallation. Since installation, no leaks have been noticed.
The removal & reinstallation of the OFH was documented with pictures. I would be happy to provide this documentation, or other information about my experience to whomever needs it to support this class action or join this action myself.

2021 330I 35,000 miles tells me oil housing needs new one! This is a 100k or more problem! $2500 to fix🤦🏻♀️
2018 Mini Cooper S at 48,000 mi. Oil filter housing cracked in exactly the same place as all the others.
Fixed it myself, but can I get some of that class action settlement money
Had this happen to both my 2016 X1 and 2018 X3 and both were in the $3500 range plus the X3 was in the shop for almost a month. BMW was absolutely no help even though this problem is all over the internet!
I am dealing with this issue right now with my 4 series!
Own a ’17 3 series at 60k miles. OFH hasn’t failed yet, but as we all know, its only a matter of time. This is LONG overdue
I owned a 2016 mini cooper s that I had to replace the housing at about 80,000.
