Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering electrical on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
While performing a 12-Volt battery jump start, disconnect, or replacement, vehicle test, and/or programming procedure- the MINI Footwell Module (FRM) may become unresponsive. As a result, one or more of the following vehicle electric system-related issues may occur: Headlights including the high beams, and/or taillights are not turning on or off Interior lights are not turning on Turn indicators are not working Instrument cluster indicator lights stay on The IHKA climate control system is not working Power windows are not working Folding mirrors are not working, and/or a Functional remote-control key FOB will not unlock and lock the doors

full bulletin at NHTSA ↗MINI electrical systems have continued to develop over the past few years. As a result, the demand on the batteries has increased. Breakdowns due to an empty battery or problems in the vehicles electrical system can have various causes, most of which are not due to the battery itself. For this reason, a battery replacement will permanently eliminate the problem only in the rarest of cases. The energy diagnosis test module helps to localize these causes. This document covers important information for the dealer on how to handle âÂÂdischarged batteryâ complaints. Without performing the energy diagnosis test plan, the root cause of a discharged battery cannot be identified. In order to

The failure pattern owners describe
Water and salt routinely enter the footwell circuit and connectors, corroding wiring and causing cascading failures. Windows lower spontaneously or fail to open after overnight parking or rain. Central locking malfunctions. When it rains, a short circuit causes all electrical components—lights, locks, windows, dash—to activate and deactivate randomly, draining the battery and leaving the vehicle stranded in traffic.
A footwell module replacement or computer reinitialization doesn't permanently fix these problems; one owner's windows went down halfway after the computer was replaced. NHTSA Campaign 23V337000 addresses the electrical system, but dealers have reported parts unavailable for extended periods, leaving owners without remedy.
Engine stalling occurred repeatedly in one vehicle after computer work, with no diagnostic codes retrieved across multiple dealer visits, though a mechanic later found a blown head gasket.
Most alarming: four separate spontaneous fires occurred in parked vehicles with no prior warning lights or alarms. One fire destroyed a residential garage and injured the family; another consumed the vehicle in a parking lot within five minutes of the owner leaving it. Burnt wires and fire damage point to underhood electrical faults. No recalls or manufacturer fixes have been issued for the fires, and inspection outcomes are unclear.
Speedometer accuracy also varies by up to 10 mph, though dealers claim this is within tolerance.

Failure modes owners describe
Window regulator / central locking malfunction from moisture ingress
Windows lower or fail to adjust after rain or moisture enters the vehicle. Water and salt corrode footwell circuits and wiring. Central locking also fails intermittently. Tied to footwell module and connectors.
When: Spring 2012 onward; typically occurs after rain or overnight parking; failures reported across 70k–150k miles
Symptoms owners cite: Windows lower spontaneously when parked overnight; Windows fail to roll up or down intermittently; Doors fail to lock/unlock properly; Water visible in footwell or passenger-side interior panels; Damp electrical panels in interior
Repairs/costs cited: Dealer replacements of footwell module/computer and connector repairs attempted. One owner paid out of pocket for lights repair due to cost; others awaiting recall parts. FRM (Front Right Module) replacement and reprogramming performed in at least one case but failed to resolve connector corrosion.
Recalls/TSBs owners mention: NHTSA Campaign Number: 23V337000 (Electrical System) issued. Multiple owners report recall parts unavailable for extended periods. Dealer informed owners manufacturer exceeded reasonable timeframe for remedy availability. One dealer offered out-of-pocket repair option.
Electrical short circuit and battery drain from moisture ingress
When it rains, short circuits occur in the electrical system causing multiple components to malfunction simultaneously. Battery drains rapidly, leaving vehicle stranded. All lights, locks, windows, and dash lights activate or deactivate erratically.
When: Occurs during or after rain; vehicles left stranded on roadway
Symptoms owners cite: All lights turning on and off randomly; Locks opening and closing randomly; Battery rapidly drained; Vehicle left stranded twice in middle of street; Short-circuit behavior triggered by moisture
Repairs/costs cited: Owners suspect footwell module issue but no repairs documented in narratives. One owner notes vehicle not included in active recall despite fitting specs and symptoms.
Engine stalling—undiagnosed, possibly related to computer malfunction
Vehicle stalls randomly while driving in various conditions (freeway merging, stop-and-go traffic, slow speeds) after computer replacement. Multiple dealer visits yielded no diagnostic codes. Mechanic later diagnosed blown head gasket, but stalling episodes preceded gasket failure and were unresolved by dealer.
When: Spring 2012 through March 2014; multiple stalling incidents
Symptoms owners cite: Random stalling while merging onto freeways; Stalling in stop-and-go traffic; Stalling at slow speeds; No diagnostic codes retrieved by dealer multiple times
Repairs/costs cited: Computer replaced after window/moisture incident. Dealer reinitialized computer but stalling continued. Vehicle taken to second dealer; no stalling reproduced during dealer test drives but continued randomly for owner. Eventually diagnosed as blown head gasket in March 2014, but owner had not yet pursued repair.
Spontaneous engine compartment fire / underhood fire
Multiple reports of vehicle fires occurring while parked or immediately after stopping. One fire occurred in residential garage while unoccupied; another in parking lot 5 minutes after owner entered store; another shortly after driving 15 minutes then parking. Fires consumed vehicle entirely or nearly so. One fire may have originated near power steering pump area. Burnt wires observed. No warning lights or alarms preceded fires.
When: Incidents from 2011–2012; one garage fire after vehicle sat parked; fires occurring shortly after parking at destinations
Symptoms owners cite: Visible sparks and fire through front grill after engine shut-off; Burnt wires visible in engine compartment; Smoke detected in adjacent residence within 2 minutes of parking; Vehicle fully engulfed in flames when discovered; No prior warning lights or indicators of malfunction
Repairs/costs cited: Vehicle(s) towed to dealer for inspection by BMW engineering (one case); others totaled by insurance. One vehicle still pending repair at dealer as of August 2012. No repair outcomes documented.
Recalls/TSBs owners mention: Manufacturer contacted in at least two fire cases. One was referred to BMW engineering for inspection. No recalls or TSBs for fires mentioned in narratives.
Warning lights and instrument panel malfunction from moisture/corrosion
Multiple warning lights illuminate intermittently or continuously—parking brake warning, tire pressure warning, unknown warning lights. Lights flicker on instrument panel. Water and salt corrosion of wiring and circuits suspected or confirmed by dealer.
When: Reported at 70k–150k miles; one vehicle at 100k miles
Symptoms owners cite: Parking brake warning light illuminated; Tire pressure warning light illuminated; Unknown warning lights remain lit; Multiple lights flickering on instrument panel; Water and salt corrosion confirmed by dealer
Repairs/costs cited: Owner given repair estimate but parts unavailable for recall work. One owner reported less than half the lights working; dealer quoted out-of-pocket cost; repair not performed due to cost.
Recalls/TSBs owners mention: NHTSA Campaign Number: 23V337000 (Electrical System). Repairs fall under recall but parts unavailable for extended period.
Speedometer inaccuracy
Speedometer displays readings 9–10 mph higher than actual vehicle speed, as verified by GPS or external observation. Dealer states speedometer is within manufacturer tolerance (10% margin of error) and provides no remedy.
When: Early in vehicle ownership; reported at 21,300 and 200 miles
Symptoms owners cite: Speedometer reads 60 mph when actual speed is ~51 mph (9 mph discrepancy); Speedometer reads 70 mph when actual speed is 62 mph (8 mph discrepancy)
Repairs/costs cited: Dealer states no repair available and speedometer is within tolerance (±10% margin of error).

See attached document for complaint.
We parked the car and 3 hours later is was on fire. It seems to have emanated from the power steering pump area but cannot tell with all the fire damage. The car is most likely a total loss.
Tl*the contact owns a 2009 Mini cooper. The contact stated that after installing a GPS system in the vehicle he became aware that the vehicle speedometer was given the incorrect reading. The contact mentioned that the GPS read 51mph and the vehicle speedometer read 60 MPH, but vehicle was going slower. The dealer stated that they were not providing any assistance given that the vehicle…
The car horn was going off randomly. I inspected the interior electrical panel on the passenger side of the car and it was damp. There is water getting into the passenger side of the car and infiltrating the panel causing this one issue and likely others. There is a recall for this problems in some places, but my vehicle is not included, currently.
