Lexus Australia is recalling approximately 7,015 second-generation IS sedans and convertibles to replace front passenger airbag inflators installed during an earlier Takata recall.

The precautionary campaign covers certain IS250, IS250C, IS350 and IS F vehicles produced between 31 August 2005 and 25 December 2012.

Lexus says no propellant degradation has been identified in recovered parts, and owners can continue driving their vehicles while awaiting the free repair.

The replacement inflators contain desiccated, phase-stabilised ammonium nitrate (PSAN) propellant, which may degrade following prolonged exposure to high absolute humidity, high temperatures and repeated temperature changes.

An inflator contains solid propellant that generates gas when ignited, filling the airbag when deployment is required. The desiccant absorbs and retains moisture to limit the propellant’s exposure to it.

Lexus had previously determined that adding a desiccant would allow these replacement inflators to remain safe throughout the vehicle’s expected service life. Subsequent investigation found the propellant could still degrade under prolonged exposure to those conditions, prompting another replacement campaign.

The company says it is not currently aware of any propellant degradation in vehicles fitted with the affected inflators in the market. There are no warning signs or symptoms associated with the condition.

Which Lexus IS vehicles are affected?

Lexus has identified the affected vehicles through its repair records, rather than including every IS built during the overall production period.

The following production dates and VIN ranges identify the vehicles covered by the campaign. Not all vehicles within these ranges were sold in Australia.

Lexus dealers will replace the affected passenger airbag inflator at no cost to owners. The work takes approximately 4.5 hours, although the vehicle may need to remain at the dealership longer depending on its workshop schedule.

Lexus Australia will contact owners with details of the recall and is asking them to keep their contact information up to date.

Owners with questions can contact their preferred Lexus dealer or the Lexus Customer Assistance Centre on 1800 023 009, Monday to Friday from 9:30am to 5:30pm AEDT. They should have their 17-character Vehicle Identification Number (VIN) available.

VIN locations vary by model, with guidance available under “vehicle identification number” in the index at the rear of the owner’s manual.
