John Cooper Works (JCW) is a British car marque now owned by BMW and it is an in-house tuning, development, and international automotive racing division for Mini vehicles. It was founded in 2002 by Michael Cooper, son of John Cooper, the racing car maker and tuner responsible for the original Mini Cooper.

In 2007, German automaker BMW acquired the rights to the name, and it bought out the company in 2008.

JCW Tuning

Cooper

The first ever JCW kit was a 126 bhp (94 kW) upgrade for the Mini Cooper. The kit consisted of the following components:

Flowed and ported cylinder head
Air filter
Cover injection tube
Uprated exhaust (from the catalytic converter back)
Remapped ECU
Decorative emblems

Despite its price tag of over €2000, this kit only offered a power increase of 11 bhp (8.2 kW), a sportier exhaust note and a crisper throttle response. The main advantage was that these improvements, though fairly minor, could be made to the Cooper without jeopardizing the factory warranty. In 2004, JCW discontinued the Cooper kit and introduced a Sound Kit for the Cooper. The Sound Kit consisted of a unique air intake system, cat-back exhaust and an ECU remap.

Common 2017 Mini Jcw problems

Based on the complaints from owners of the Mini JCW 2017, several common problems have been highlighted:

Crank-Bearing Issues: Owners have reported crank-bearing issues on early engines. While it may be possible to change the bearing, this problem can lead to significant complications. Crank-bearing problems can affect the engine's performance and longevity, potentially resulting in costly repairs if not addressed promptly.
Front Overhang Length: The F56 Mini JCW design features a longer front overhang compared to previous models due to new crash test regulations. This longer front end can impact the car's aesthetics and handling, potentially affecting maneuverability and overall driving experience.
Headlight Upgrades: The F56 Mini JCW comes with bug-eyed headlights that were upgraded to LED versions during the LCI facelift. Some owners have reported issues with these headlights, particularly with the distinctive 'halo' daytime running lights that also function as indicators. Problems with the headlights can affect visibility and safety while driving.
Rear Light Clusters: The rear light clusters of the F56 Mini JCW were changed to the Union Jack LCD design during the LCI facelift. While this design change added a unique touch to the car's aesthetics, owners have mentioned issues with these rear lights. Malfunctions in the rear light clusters can impact visibility to other drivers and compromise road safety.
Color Options: While not a mechanical issue, some owners have expressed concerns about the available color options for the F56 Mini JCW. Specific colors like Rebel Green, which is a JCW-only color, may not appeal to all buyers. Limited color choices can be a drawback for those looking for more variety in personalizing their vehicle.

These common problems reported by Mini JCW 2017 owners highlight various aspects of the car's design, performance, and functionality that may require attention or consideration for potential buyers. Addressing these issues promptly and ensuring proper maintenance can help mitigate any challenges associated with owning this particular model.

UNKNOWN OR OTHER PROBLEM

Date Of Incident: 2023-09-01
VIN: WMWXM9C5XHT
Components: UNKNOWN OR OTHER
Summary: This car has the Steptronic automatic transmission. There is a mechanical actuator that moves when the transmission is placed in Park. Apparently an electronic circuit is completed telling the computer the car is in Park. There is a small spring on the actuator arm that moves it. If that spring breaks the arm does not move and the computer does not "sense" Park. A warning light and alarm go off "Secure vehicle from rolling". My online research indicated this is a fairly high failure item it both MINIs and BMWs. From the pictures I've seen of the actuator arm and spring this appears to be a very poor design. The repair runs anywhere from $2000 to $4000 depending on the dealer repair shop. I believe this item shoud be repaired as a Recall item!
