Recalls for the 2003 Mini Cooper S: 2
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.
On certain vehicles, the lower screw connection of the rear struts to the chassis may fail. The head (Top) of the screw securing this connection may break. The remaining portion of the screw will still hold the strut in place. If left unattended over a period of time, and depending on driving conditions, the remaining portion of the screw may break.
A recall may cover only some cars of a model year; the campaign size counts every model and year it lists. Enter your VIN at nhtsa.gov/recalls: dealers fix open recalls free.
