Vehicle Weaknesses 6
The Duster II also shows axle components with a five-fold above-average defect rate at the very first MOT. Tie rod ends and steering joints are among the most common weak points.
The Duster II brake lines tend to corrode after four years of operation.
A recall was issued for vehicles produced June to July 2023 due to possible cable connector defects that could affect the airbag and drivetrain.
As with its predecessor, the Duster II headlights and tail lights show above-average defect rates at MOT.
Four-wheel drive vehicles develop oil leaks in the transfer case area more frequently after a few years of operation.
The front seats in the Duster II provide little lateral support. Rear seat passengers can slide out of position in corners on the barely contoured bench.
