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.

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.

My car is little over 102,000 miles. It suddenly stopped, near my house and I was not able to start again. Replaced battery, however found out that high pressure fuel pump failed. Warranty reported by mini expired earlier this year. This could be safety issue, if car stops in middle of highway.

Loud rattling noise when accelerating coming from the engine. When I come to a complete stop car has turned off, sometimes it cranks for a bit to start up. Also while driving losses power and car decelerates slows down and also pulls like if was out of gas. White smoke when you press on gas.

My fuel rail was sipping with gasoline. When I brought my car to a mini dealer, they claimed that it was a wear and tear problem and refused to acknowledged that it was a design flaw. The fuel rail was plastic and the leak was at the seal between the plastic parts. If the fuel rail is metal and is soldered, this problem would not have happened. Having a fuel rail that leaks could severely damage the engine and cause a fire. *Tr

Vehicle was driven 1.2 Miles for first run of the day. Temp was 48 f. Car was in drive at stoplight when engine accelerated beyond max rpm. Car lunged forward into intersection and a lot of effort had to be applied to brake to keed car from going any further. Driver grabbed gear shifter and shifted to neutral and having slipped into reverse. Engine rpm then subsided and vehicle was then driven 14 miles with no further incidence. *Tr

I have been experiencing a major flaw with oil supply/return lines to the turbo. A condition exists where if left unattended and uncared for creates the high risk of fire and subsequent loss of engine/vehicle. This event can happen at any time the car is being driven and/or later parked. The risk is created when oil accumulates, either through time or over a leisure drive, and collects near/on the exhaust manifold & turbo components, both of which operate at extremely high temperatures. It is becoming a daily...

task to look under the car hood and investigate for accumulation of oil near these parts due to the fact that the car smells of burning petroleum. Need I be more apparent of burning oil that will burn and destroy a car due to a faulty product? This has been occurring for the majority life of the car but he issue has never been professionally addressed due to disregard of the mini/bmw dealerships to accept this design flaw. If researched further, there are many standard examples of this design flaw and numerous descriptions, images, examples, forums, and complaints of this flaw occurring in many cars of various styles, mileage, and trims occurring within the same year model of 2007. I have also experience many of the major flaws already listed and complained about on the nhtsa such as the ??Death rattle?? Belt tensioner failing (luckily no catastrophic engine failure and which has been listed numerous times on nhtsa, numerous), valve cover replacement (also listed), etc. Nhtsa, address this problem as it is an avid and dangerous safety issue. The common person does not check under the hood daily and its only time before someone parks their mini in a garage and the home goes down in flames. I personally don??T park the mini in the garage for fear of fire. Do not repair the mini with the same faulty oil line design. Recall design. *Tr

Turbo oil supply line from engine to turbo leaking excessive oil requiring replacement. Poor engineering design of compression fitting led to premature failure. Continued operation of vehicle with this condition would result in catastrophic engine and or engine turbo failure. Mini of marin was notified of the ongoing issues and were told they hadn't heard of the issue. Car smokes up if driven slow. Must be addressed in recall. *Tr

2007 Mini cooper. Consumer states problem with fuel line *tgw the consumer stated she noticed a very strong smell of gas inside the vehicle. The next day, the smell wa worse. She took the vehicle to her local mechanic to see what the problem was. According to the mechanic, the fuel line had been worn through from improperly installed heater hose clamps, which was an original installation from the factory. Over time, the clamps rubbed through the fuel line, which led to gas leaking from the fuel line, and spraying onto the exhaust manifold. The consumer stated the fuel line has since been modified on later models. *Jb

Eight months after mini of concord replaced my high pressure fuel pump for the gasoline leak and strong gas smell within the cabin, again the gas smell started up in the cabin (for all trips). I took it back to mini of concord (this is 22 months after buying car), and they again found a leak in the high pressure fuel pump and line, and replaced the parts - again. This was the fourth replacement of the high pressure fuel pump on my car! They also replaced the timing chain tensioner because of the loud noise it was making on startup. And the inlet camshaft position sensor. *Tr

As I approached the street on where I live, the car started to severely shake and jerk , as if power was not going to the engine. I was able to park it on my driveway, but the next morning, the car had to be towed to the dealer because it would not start. When the car arrived at the dealer after being towed in, the car could not be jump-started, even after several attempts. Two weeks prior, I had brought my car in for service because the check engine light came on. They replaced the timing chain and found several...

misfire faults, which were supposedly corrected. The cylinder head was removed and disassembled and found to have carbon build up. The intake valves and exhaust valves were cleaned. Since the incident, the car is still at the dealer. An extended road test is scheduled to be performed within these next few days. No word on what has caused the car's engine to die. *Tr

The vehicle will not start. This occurs randomly (mine has had this happen twice in the last month). Vehicle will not start for several days then apparently all of a sudden will start again. Vehicle was towed to dealer after the first time but they said they could not recreate the condition, so nothing was done. No codes were stored in the computer. This second time it has not started for the last 4 days. Engine will crank, I pulled a sparkplug and put it in the ignition coil and it would fire, but the engine...

will not start, like it isn't getting fuel. This could be a safety issue if you need to rely on your car to be somewhere. If it wont start I am worried that it could also die while going down the road, which would be a huge safety issue, although it has not done this, its just a concern. I do not expect a car that is only a little over 3 years old to not start. I have contacted mini usa but they are hesitant to recommend anything other than to have it towed to the dealer again. *Tr

The vehicle is constantly sputtering and loosing power. It hesitates on taking off and the performance is down significantly from when it was originally purchased. I have brought the car to the dealers several times and the stated that this was due to the fact that I was using poor quality gas. Since then I have changed to premium gas and the problems still persist. I finally brought the car to a renowned mini mechanic and he explained to me that this is a recurring problem with the fuel pump. *Tr

I have experienced multiple failures of the fuel pump on my 2007 mini cooper 7. It is now experiencing the early symptoms for a third time. The dealership failed to fix the problem on 4 occasions prior to the fuel pump seizing. They returned the "repaired" vehicle, and the replacement fuel pump was leaking (was overcome by the fumes trying to drive it home from work the same day it was returned). They repaired it a second time, and I had it checked by a second dealer. What are my rights in this situation? I am...
