2016 MINI COOPER Complaints

Had recurring engine warning light which will only reset for one ignition cycle. Took to dealer to read code and result was "LIN bus communication fault for environmental air catalyst sensor". This is the same problem drivers of the Mini Cooper S model have reported and received an extended warranty from Mini of North America (15 year / 150000 mi) with replacement of sensor and radiator. However, talking with Mini of North America, the extended warranty does not apply to the base model 5-door Cooper because not enough complaints have been recorded. If more people report this issue, it could be covered just as the S-model is being covered. In the meantime, the car will not pass an emissions inspection with the light on, and Mini dealer wants $2000 to replace radiator and sensor. Car currently has about 70,000 miles on it, but engine light as been on for approximately 15 months (emissions inspection is required every 24 months). I have a decent code reader, but it only provides "U019D generic code" which is why I took it to Mini dealer.

Rear passenger tail light casing/bucket had burnt connections. Replaced casing/bucket and bulb. Worked for short time, tail light failed a second time. Casing/bucket & bulb replaced, again worked for short time and then went out. Took vehicle to another mechanic after passenger side headlight failed. New mechanic checked casings/bucket - connections looked okay, however both wiring harnesses were severely burnt. Headlight harness was all bare wires. Mechanic unable to determine cause of the severe heat that would lead to both the headlight & taillight wiring harnesses becoming burnt so severely. Mechanic was concerned of the potential for this issue to cause vehicle fire. Suggested to follow up with dealership to have lights & wiring harnesses on Driver side checked After research online regarding this year/make/model - I have found numerous other reports of other owners experiencing the same issues with burned wiring harnesses causing both front and rear light failure with no known causes.

My Mini service adviser said the timing case cover is seeping and will continue to get worse until the seep becomes a leak and the oil starts dripping onto the manifold, potentially creating a fire. It is at the seepage stage now and therefore my extended warranty will not fix it. My Mini service adviser said she doesn’t think it is dangerous yet but I have to keep an eye on it as this is a common problem on Minis. They quoted me a price of $934 to replace the timing case cover itself. I researched the problem online and found this is a common problem and will need my attention to ensure it doesn’t get dangerous before I’m able to get it repaired.

Notes from Beckley Auto Service from 2-12-24. "Verified warning light on, retrieved one code for LIN bus communication fault for environmental air catalyst sensor. Checked and found technical service bulletin (TSB) from Mini Cooper M13 01 19. The chemical composition of the fan shroud contaminates the sensor. This repair involves the replacing of the radiator with each sensor and fan shroud. Should be covered under Mini Coopers emissions warranty. Called Mini Cooper of Des Moines(Jerimiah) and was advised that this vehicle does not have and extended parts warranty/warranty extension on the environmental sensor. Would recommend contacting Mini Cooper Customer service or Mini Cooper North America for assistance." I did contact Mini Cooper customer service North America and was told my vin does not fall within this TSB. When asked why my vehicle with the identical engine and issues specified in the TSB is not covered I was told, "I don't know."

* Component/ system that has malfunctioned and failed - The Driver side tail light circuit board and pig tail malfunctioned. The connector has corroded and the plastic plug housing looks melted on the earth / brown wire. This in return damages the the ground connection for the tail light rendering the turn signal the reverse light and the brake light inoperable on the effected side. YES, MY VEHICLE IS AVAILABLE FOR INSPECTION AT ANY TIME. *A driver behind an affected vehicle could be confused which could increase the risk of a crash. *The vehicle has been inspected by a licensed MINI Dealership. They failed to report two of the three nonworking rear lights that have failed due to the connector becoming corroded. The corroded plastic plug housing becomes melted on the earth / brown wire. This in return damages the the ground connection for the tail light rendering the turn signal and brake light inoperable on the effected side. In this case it is the rear driver side. *There was/ is no warning until long after the first second and/ or third rear light(S) were not operable. Intermittently (sometimes) a warning will popup when turning on the vehicle. The vehicle will not warn the driver about and and / or all three lights each and every time the vehicle is turned on. ALSO while the vehicle is in drive or in reverse , the driver will not have any warning what so ever that the three lights 1. The driver side rear break light 2. The driver side rear reverse light 3. The driver side rear turn signal are not working due to a malfunction. * note that there is a very strong burnt/melted smell that comes from the connector as well. I could smell it on my fingers after removing the connector so I could check the rear bulbs for replacement. Please note the 1st photo-this is how the dealership left my connector after their assessment. Additional photos are of the connector/ pig tail/ circuit board corrosion. Intermittent warrnings for some of the nonworking lights.

There is a design issue resulting in failure of the connector for the rear tail light assembly. The connector corrodes and the plastic plug housing melts. This damages the ground connection for the tail light rendering the turn signal and brake light inoperable on the effected side. This has happened on the right rear of our Mini Cooper JCW hardtop. Searching on the web shows this to be a common problem for the F55, F56 & F57 MINIs. As this failure makes the car brake light system non-compliant with FMVSS lighting requirements, there should be a recall to address this issue.

Error signal "Secure vehicle with parking brake when stopped" Mini dealer says "common problem" with Mini transmissions and always due to fluid leaking thru shifter onto gear shift mechanism. Lots of forums stating this is common. Unclear why Mini not taking responsibility for this due to poor design. How many cars ever get a failure such as this? None that I can find except MIni and BMW with similar transmissions.

*The condensation drain hose is not properly draining the condensate from the vehicle. The micro-filter is is absorbing condensate water from the evaporator housing. *After a while the water that sits, turns to mold. You dont know about it until it gets to that point. You breathe in mold, constantly until you figure out where it is coming from. *The problem has been confirmed and also confirmed that its a known problem to have with these cars *Yes the care has been inspected by the dealer. *There are no warnings at all

About two days ago I noticed my MINI started showing an error every time I got into the vehicle saying "Secure vehicle against rolling" I have seen numerous different discussions online but none seemed to come to a solution or single cause of this error. Everything still shifts completely fine in the car, the parking brake engages, and the car shifts into park fine. Seems to be a common problem, it's a shame MINI has not addressed it as a recall.

Rear tail lights have a bulb socket and a 6-pin connector that have a tendency to burn at the brown ground wire where the connector and bulb socket meet. Requiring replacement of both parts and disabling the rear tail light (brake, turn, and reverse lights). It requires rewiring the 6-pin connector and replacing the bulb socket. About $60 in parts. When this occurs it an alert comes on the dash of a malfunction to all three rear lighting functions. One or all three of the lights can be affected. However, due to the complexity of the parts and labor required, it can be burdensome for people to diagnose and then afford to repair, if they don’t know how to repair themselves. Web searches helped me diagnose the issue and find the burnt connections on our vehicle, with folks commenting of a known issue on MINIs and BMWs for this type of connection, surprised it hasn’t been part of a recall.
