In owners' own words
When accelerating from 30 to 40 miles an hour/shifting from 3rd to 4th gear, my transmission would rev up the rpms and my car no longer accelerates.
(2005 Mini Cooper transmission) vehicle does not move from standing position when accelerator depressed. Suddenly jumps into gear (In drive or reverse position).
At low miles the transmission has to be replaced. No fore warning just gone. I'm trying to drive and at 10 MPH I'm revving at up to 3000 rpm's.

Recalls for the 2005 Mini Cooper: 4
The affected vehicles may experience temporary or permanent loss of the electro-hydraulic steering assistance. If the vehicle experiences a loss of power steering assist, extra steering effort will be required at lower speeds, potentially increasing the risk of a vehicle crash.
Due to manufacturing, installation, and exposure issues, the front passenger seat occupant detection mat may not function properly and, as a result, the front passenger air bag may not deploy in a crash. An improperly functioning mat may cause the passenger frontal air bag to be inactive when the seat is occupied, and in the event of a crash, the air bag will not deploy, increasing the passenger's risk of injury.
These headlamps fail to conform to the requirements of federal motor vehicle safety standard no. 108, "Lamps, reflective devices, and associated equipment." These lamps do not contain the required amber side reflectors. Decreased lighting visibility may result in a vehicle crash.
These headlamps are missing the amber side reflex reflector which fails to conform with the requirements of federal motor vehicle safety standard no. 108, "Lamps, reflective devices, and associated equipment." Without the amber side reflex reflectors, the lighting visibility may be affected, possibly resulting in a vehicle crash.
