What stands out
Electrical accounts for 42% of every owner complaint on file for this vehicle — the dominant problem area across 5 categories tracked.
Owners have filed 27 electrical complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
The failure pattern owners describe
The 2012 Mini Cooper Convertible has a widespread Footwell Relay Module (FRM) failure that disables power windows, door locks, turn signals, and emergency flashers. The FRM enables communication between the instrument panel and engine control electronics; when it fails, the vehicle becomes undriveable. Owners confirm the module is vulnerable to inrush current surge when a fully-charged battery is reconnected and lacks protection from voltage spikes caused by EMI or electrical storms. Replacement costs over $1,000. BMW/Mini issued recall #23V-337 in May 2023, but parts remain unavailable more than a year later. Some dealers marked the recall complete without actually replacing the module, then charged owners for the "recalled" repair.
Owners also report engine fires or fire-risk conditions—burnt circuits, melted plastic, and coolant leaking over exposed wiring—triggered by pothole impacts or occurring spontaneously while the vehicle is parked. One owner's vehicle caught fire in the driveway with the windshield wipers running on their own. BMW recalled this defect in South Korea following a fatality, but U.S. dealership technicians claim they're unaware of the issue and repair parts are unavailable.
Additional failures include moisture intrusion into underbody computers (one placed unprotected under the beverage holder) causing starting failure and battery drain, and rear brake lights that melt and burn repeatedly despite repair.

Failure modes owners describe
Footwell Relay Module (FRM) failure
The FRM is a critical component that enables communication between the instrument panel and engine control electronics. When it fails, essential vehicle functions become inoperable. Owners report the module is vulnerable to inrush current surge when a fully-charged battery is reconnected, and inadequately protected from induced voltage surges (EMI, radar, electrical storms). The part costs over $1,000 to replace.
When: Varies; some owners report failure at 54,000–142,000 miles; others report immediate failure after purchase of used vehicles
Symptoms owners cite: Power windows inoperable; Power door locks inoperable; Turn signals inoperable; Emergency flashers inoperable; Key fob non-functional; Vehicle rendered undriveable; Unknown warning lights illuminate; Battery drains; Vehicle fails to start or restart after power loss; Display screen goes black; Rear blinker does not signal
Codes mentioned: Multiple codes (owner in #12 reported 9 codes for footwell module)
Repairs/costs cited: Parts unavailable for extended periods despite recall notification. Replacement cost exceeds $1,000 (parts and labor). One owner paid $759.18 for FRM replacement and was initially promised reimbursement by BMW/Mini under recall #23V-337, then denied. Dealers initially refused to replace modules, claiming no corrosion visible, then marked recalls as complete without performing the repair.
Recalls/TSBs owners mention: Recall #23V-337 (Campaign Number 23V337000, Footwell Control Module-FRM) issued May 2023. Parts reported unavailable as of multiple complaint dates. BMW/Mini denied reimbursement to owner who paid out-of-pocket for repairs, citing no remedy available. Dealership technicians reportedly unaware of defect; some dealers falsely marked recall as complete without replacement.
Moisture intrusion into underbody electrical components
Water enters the front passenger footwell and junction box, causing corrosion and failure of electrical components. One owner discovered a computer located under the beverage holder with no moisture barrier or protective housing and no owner's manual warning.
When: Triggered by rain or wet conditions; one owner discovered issue after water entry through front passenger footwell
Symptoms owners cite: Vehicle fails to start; Moisture found in junction box electronics; Moisture found in computer under beverage holder; Unknown warning lights illuminate when it rains; Power windows fail in wet weather; Corrosion on electrical connectors
Repairs/costs cited: One owner paid $1,200 to repair computer damage caused by beverage holder moisture intrusion. Another owner faced water damage to junction box and footwell module from front passenger footwell water entry.
Recalls/TSBs owners mention: No manufacturer response documented in narratives. No design changes or protective measures mentioned.
Engine electrical short-circuit and fire risk
Multiple owners report engine compartment fires or fire-risk events involving burnt circuits, melted plastic, and coolant leakage triggered by electrical faults. One owner reports vehicle caught fire while parked in driveway with windshield wipers activating on their own. Another reports burnt circuits and exposed wiring following pothole impact. An owner notes BMW issued a recall for this defect in South Korea but it remains unaddressed in the U.S.
When: Triggered by pothole impacts or spontaneous while vehicle is parked off
Symptoms owners cite: Engine temperature warning light illuminates; Engine power reduced / limp mode; Engine failure light appears; Vehicle stalls with sputtering; Burning smell; Smoke from engine compartment; Burnt circuits visible; Burnt plastic; Coolant leaking over engine and exposed wiring; Windshield wipers activate when vehicle is off; Fire in engine compartment or under steering wheel
Repairs/costs cited: No repairs completed; parts unavailable. One owner had vehicle towed to service center; technicians claimed repair parts unavailable. Vehicles required towing after stalling.
Recalls/TSBs owners mention: BMW issued recall for 2012 Mini Cooper S Roadster in South Korea due to this defect and a reported fatality. U.S. owners report no corresponding recall on their VINs and dealership technicians unaware of the defect.
Ignition/DME (engine control module) failure causing limp mode and stalling
Early failures in 2012 Clubman models causing loss of power, limp mode, and rough running. One owner purchased the vehicle new with 6,498 miles and experienced multiple failures within weeks despite repeated dealer repairs (spark plug replacement, DME replacement, fuel injector replacement).
When: First failure at ~9,000 miles; repeated failures within weeks of repair attempts
Symptoms owners cite: Loss of power on highway; Limp mode activation; Vehicle shaking; Rough idle, rough acceleration; Nearly stalls at every idle; Car sounds like a 1970 VW Beetle
Repairs/costs cited: Dealer replaced 4 spark plugs, then DME and 4 fuel injectors, but failures recurred. Vehicle remained at dealer for multiple weeks with repeated towing required.
Rear brake light melting and burning
Rear brake lights melt and burn, then melt again after repair, requiring full taillight replacement and causing additional damage.
When: Not specified
Symptoms owners cite: Rear brake light burnt and melted; Melting recurs after repair; Taillight damage propagates
Repairs/costs cited: Initial repair of burnt light; melt recurred and caused further damage requiring whole taillight replacement.
