Toyota Australia has recalled 23,957 examples of its HiLux ute and Fortuner SUV.
According to the recall notice from Toyota, "improper moulding conditions" during production of the resin piston inside the vehicles' brake boosters – which, as its name suggests, amplifies the braking force applied when the brake pedal is pushed – could cause the piston's strength to degrade.
Should this occur, repeated use of the brake pedal over time during normal driving could cause the piston to break, potentially leading to a loss of power braking assistance and therefore increased stopping distance.
All affected diesel HiLux and Fortuner models were manufactured between June and December 2018, with VINs ranging from 00221362 to 01220257 for HiLux and from 00002957 to 00208596 for Fortuner – although not all vehicles within those ranges are affected, nor were sold in Australia.
Toyota's local arm has confirmed it will contact owners of affected vehicles by email, text or mail, providing details of the recall and encouraging them to organise a free fix with their nearest Toyota dealer.
Replacing the brake booster assembly will reportedly take around three hours.
Owners with additional questions can contact their Toyota dealer, or call the Toyota Recall Campaign Helpline on 1800 987 366, from Monday to Friday, 8am to 7pm AEDT.
