Parking brake caliper shaft boots incorrectly sealed
Due to improper sealing of parking brake caliper shaft boots water might penetrate inside and rust the shaft. As the result of continuous use the rust will erode into the internal caliper and the shaft becomes stuck causing decreased parking brake force. Due to improper manufacturing process automatic adjuster for brake pad clearance of rear brake caliper might not work properly. As the result as brake pad wear the clearance is not correctly adjusted and brake force becomes insufficient to hold a vehicle. In the worst case scenario parking brake will not work even though a lever is fully operated and parked vehicle may move.
Fix: Anti-rust coating (Fluorine) has been applied to parking brake shaft from 27/01/2016 supplied parts & the Inspection process for the caliper has been changed from 14/12/2014 supplied parts.

Tailgate gas spring end cap may corrode and come off
Anti-corrosion treatment of the gas spring end cap in production was insufficient. The tailgate gas spring end cap corrodes to such an extent that the gas pressure inside can force the end cap to come off. In the worst case the end cap can hit the customer and/or the tailgate can fall down suddenly and result in possible injury.
Fix: The anti-corrosion coating has been improved in vehicle production. On affected vehicles the rear tailgate gas springs will be replaced with improved gas springs.

Recalled models: ASX · 5,359 vehicles
Power steering assistance may be inoperative
