2007 Mini CooperElectrical systemLightsFuel systemFire

What happened: Vehicle has experienced failure of the Footwell Control Module (FRM) and associated wiring harness in the driver footwell area, consistent with NHTSA Recall 23V-337. Symptoms: • Exterior lights (headlights / taillights) remain illuminated far longer than normal after vehicle shutoff, sometimes not turning off at all. • Inspection revealed melted wiring, melted connector plugs and receptacles for headlight/taillight circuits. • Water was found in driver side footwell in the past / under carpet...

padding. Carpet pad is saturated. This is the same failure mode described in Recall 23V-337: "Due to a number of contributing factors, over time, the FRM could become susceptible to corrosion. Eventually, the corrosion could potentially result in a short circuit, resulting in a potential thermal event which could increase the risk of a fire or injury." Safety risk: Melted wiring and connectors create short circuit and thermal event risk, including fire risk while vehicle is parked and unattended. Lights failing to shut off creates dead battery / loss of exterior lighting control. I am concerned about vehicle fire. My vehicle shows evidence of having caught fire at the headlight and receptacle point. Recall history: Vehicle is included in NHTSA Campaign 23V-337000 (MINI Recall 23V-337 - Footwell Module Moisture/Water Intrusion). I was told remedy is still being developed / parts unavailable, or that additional wiring harness damage beyond the FRM itself is not fully covered. Dealer has inspected the vehicle and has completely disregarded the recall, which was the reason why I brought it in and have quoted me customer pay estimates for repairs covered under the recall. I am filing this to document that Recall 23V-337 failure has resulted in melted wiring harness components beyond just the FRM module, and to request NHTSA evaluate whether the current recall remedy fully addresses wiring harness damage caused by prolonged FRM corrosion / lights staying on.

2015 Mini CooperEngine & coolingFuel system

Lower Engine Support and Passenger Engine Mount damaged as per routine inspection by dealer in Feb2025. Never diagnosed before. Repair done by independent service center in Feb2025 and I have receipt of approximately 1K. Also, since 22feb2025, I am not able to add fuel to the tank because the pump stops constantly and causes spill of fuel. This can cause fire. Never happened before. Tried at least 4 different gas station and same result. Dealer charges over $200 to perform inspection/diagnostics. Not done yet. Repairs to fuel tank are in the thousands. No warning in the car dashboard for none of the issues. Car with less than 80k miles.

December of 2023. It went in and out a couple of times before they were able to replicate the problem. First they replaced the EME module and that worked for about 2000 miles before it started acting up again. Took it back to the same dealership in April when it started acting up. They updated the EME software and replaced a high voltage connector that was corroded. This repair took them until July 2nd. I went to pick up the car and made it about 3 blocks from the dealership it shut itself off on me. Took it back right away. They have had the car since then. Lastly I informed them about the most recent recall back on august 29th and it still shows as incomplete.

2007 Mini CooperElectrical systemBrakesFuel system

The vehicle has been presenting issues with breaks, electrical issues, turning off while driving, misfires, air bags don't work, ADAS sometimes don't work, the vehicle chokes and has difficulty running at times, among other issues. There has been a recall since last year and I've tried contacting the manufacturer multiple times, but the issue has not been fixed yet. All of these problems are a great safety hazard for me and my family while on the road.

2015 Mini CooperFuel system

The fuel filling nozzle turns off repeatedly while trying to fill the fuel tank and spills out causing a safety and environmental hazard, regardless of the pump being used. As a result, no fuel goes into the gas tank, instead it goes all over the car and the ground.

2015 Mini CooperFuel system

Fuel tank causes gas pump to click off after dispensing a tenth gallon of gasoline. Gas spills from gas tank while removing pump creating a safety and environmental hazard. Fuel tank will not accept gas at pump. No warning lamps, messages, or symptoms were present prior to the failure. Mini Cooper dealership stated that service valve in tank has failed and entire fuel tank must be replaced.

2009 Mini CooperFuel system

The problem was that the gas pedal began to stick. Suddenly it began to idle at 4000 rpm. I had to reach down and pull up the gas pedal while driving. I had it replaced a few weeks ago. Then I received a letter from Mini about a footwell control module. It sounds like a similar corrosion problem and it needs to be fixed as well. I had it looked at several times before it was fixed properly because a dirty throttle body can cause it to idle too fast

2009 Mini CooperFuel system

The high pressure fuel pump failed. There was a class action settlement and a warranty extension campaign for this part. Mini refused to warranty my vehicles h/p fuel pump stating it was only covered for 10 years or 120,000 miles. My vehicle only has 71,312 miles. I was informed by a local news source that manufacturers are required to honor the recall for 15 years per NHTSA, and that I should file a complaint. Please help. Thank you very much.

2015 Mini CooperFuel system

When refueling, fuel is rejected after dispensing about 1/8 US gallons, about 4 oz. Of course, fuel spills are a hazard - both in possibly of fire, and to the environment - by contaminating ground water. Dealer said that there are several solenoid operated valves and replaced fuel tank and fill pipe, a cost to me of $2400.00. There are many reports of this on social media, one person suggested holding the fuel nozzle upside down which made a larger spill.

2015 Mini CooperTransmission & drivetrainFuel system

When refueling, nozzle kept shutting off, a gallon was pumped after nine attempts, also fuel erupted as the fill tube was filled with gas. reluctant to drive this car not knowing how much gas is in the tank. The needle shows less than 1/4 and miles remaining fluctuates between 80 and 110 miles. We are told that this problem exists in many mini automobiles, dealer has replacement gas tanks, but same problem exists Parking our Mini, indication of "roll back" is possible when car is parked. Shifter unit was replaced due to torsion spring.

The fuel filling nozzle turns off repeatedly while filling the fuel tank, regardless of position of nozzle, pressure used, station used. In an attempt to remedy, Mini Service Technicians replaced tank vent valve but it did not correct the issue. I am unable to fill my gas tank.

I can not put gas into my car. I have had the charcoal canister replaced. I am now being told that I need a new fuel tank. I've also been informed that this is a reoccurring problem in 2015 mini coopers.

2015 Mini CooperFuel system

Fuel tank shuts off the gas pump no matter how much gas is in the tank. Faulty fuel tank vent (purge) value is causing the issue. This is a known issue on Mini's. A voluntary recall has been issued for 2016 Mini's, but this problem is also happening on 2015 Mini's. Dealership as well as another auto service store has replicated the issue. Check engine light is lit up as well.

Unable to fill gas as pump repeatedly shuts-off while trying to fill and would even over flow out of the filler neck. Tried 2 different pumps at local QT without luck.. Drove up to local Phillips 66 with exact same issue. Found several other owner with similar issue and found the following Service Bulletin posted on "NHTSA": https://static.nhtsa.gov/odi/tsbs/2015/MC-10147283-9999.pdf My vehicle build date is not covered under this Service Bulletin, however, suffering exact same issue.

2015 Mini CooperFuel system

Fuel tank did not allow me to input fuel. Pump clicked off immediately. MINI issued a service bulletin on the problem in 2015. I have been advised the entire fuel tank must be replaced, and have heard from other MINI owners this is a systemic problem. If I had been traveling and this problem had surfaced I would have been stranded. The repairs warrant warranty coverage on the part of MINI. See service bulletin SI M16 01 15. https://static.nhtsa.gov/odi/tsbs/2015/MC-10147283-9999.pdf
