Around 41,000 previous-generation Shoguns sold in the UK between 1990-1999 and 16,000-20,000 grey imported Pajeros and Monteros registered elsewhere between 1989 and 1999 are subject to a Mitsubishi free-of-charge 'Direct Customer Service Campaign' to correct a steering problem.

The Pitman arm ball stud within the steering of these three and five door, petrol and diesel models, can corrode and could fail. Eleven cases have been reported in the UK.

The current range of Shoguns sold from 2000 onwards and the original range sold in the UK from 1983-1989 is not affected.

This campaign is taking place only in the UK because virtually all the reported incidents have taken place in the UK.

Mitsubishi says that two accidents with no injuries have been reported as a result of the failure of this component. Water, grit and mud intrusion under the lip of the dust boot covering the Pitman arm steering joint has in some cases caused excessive wear. Continuous heavy use with repetitive force, driving in severe off-road conditions for instance, could cause the ball stud to break with a loss of steering control.

Mitsubishi has decided that the Pitman arms on all Shoguns of this generation should be changed irrespective of whether a fault has already been found on a vehicle and rectified during a service or MOT.

Mitsubishi in the UK have also decided to rectify unofficially imported Pajeros/Monteros sold by grey importers.

Initially owners of official Shogun vehicles will be advised of the service campaign by mail and asked to contact their local Mitsubishi Motors dealership to make an appointment to have the Pitman arm changed on their vehicle. According to Mitsubishi, a new arm can be fitted in one hour. In June, owners of Pajero/Montero vehicles, where known, will also be contacted by mail and advised to follow the same procedure. Mitsubishi will also be publicising the campaign via the editorial columns of newspapers and motoring magazines as well as advertising in selected press.

Stephen Blackburn Director of After Sales for Mitsubishi in the UK said: "We have taken a positive view that this part needs to be changed so we and our dealers are getting on with it. There is no need for everybody to rush at once; it is a case of making an appointment with the service department at the Mitsubishi dealership. We are also taking the equally positive view those owners of grey imports should have their vehicles attended to as well. Whilst the grey imports are with our dealers the customer will have the knowledge that their details and the details of their vehicle are now recorded for future reference."
