The company is looking to inspect 332 of its RG Mitsubishi Colt models sold between June 1 and August 23 this year to inspect the rear torsion beam suspension bolts, as part of a global recall of 1468 vehicles.
"In the worst case, driving the vehicle on rough roads may result in the bolts coming loose and possibly detaching, resulting in decreased vehicle stability," the recall notice said.
The company's notice also said a stone chipping resistant agent, part of the paintwork sprayed to the underside of the vehicle, may have been applied where rear torsion axle retaining bolts are located.
Mitsubishi spokesman Paul Stevenson said only a small number of vehicles were in customer hands - the bulk of the vehicles were still on the docks or in dealer stocks and had already been checked.
"There have been no incidents in Australia, it's only when it's on severely corrugated roads that the bolts get loose. Where the bolt goes in it should be masked - there was a month where the area around that hole wasn't masked," Paul Stevenson said.
Mitsubishi is contacting affected customers by letter and owners with concerns are advised to contact their Mitsubishi dealership for inspection of the retaining bolts.
