CITROEN announced a problem with the C1 affecting a total of 169 vehicles.
A possible substandard tapping of one or more of the wheel stud holes may result in a reduction of the wheel stud to hub torque setting. Vehicles built from 5/1/2009 to 5/31/2009 are at risk.
The following remedial action is necessary to address this problem. Recall affected vehicles and replace hubs.
If you think that your vehicle may be affected by this recall you should

who will be able to confirm whether or not your car is safe and arrange its free repair if necessary.
