MG told CarsGuide the issue was raised by overseas owners and that a fix was being carried out for Australian buyers.
"With help of all the rich insights from customers abroad, we've taken this opportunity to put the new steering damper in all XPowers as part of our Pre Delivery Inspection process both in Australia and NZ," an MG Motor Australia and New Zealand spokesperson told CarsGuide.
"While this will cause some delays in delivery, we believe that this upgrade will further enhance the driving experience through improved handling and steering response without compromising safety.
"As part of our ongoing commitment to customer satisfaction, MG Motor Australia and NZ are passing on this upgrade free of charge to both existing and future (MY23 & MY24) XPower customers."
MG told CarsGuide the delay would last two to three weeks as the vehicles are fitted with the new part before delivery to customers.
A steering damper is a shock absorber in a car's steering system which adds better stability.
MG said only 15 owners had received their cars before the steering component could be added, but said all had been contacted and would have the fix carried out as soon as the dampers were available.
