Recalls: Mercedes-Benz X166 GLS-Class

2015-16 Mercedes-Benz X166 GLS: front passenger airbag may not deploy

In December 2016, a recall was issued for Mercedes-Benz X166 GLS vehicles that were available for sale in Australia from 1 June 2015 to 31 March 2016. In these vehicles, incorrect software coding within the front passenger seat occupancy recognition control unit could result in the airbag system not recognising an occupant in the front passenger seat. In the event of a collision, the front passenger airbag may therefore not deploy and the risk of injury to the occupant would be increased (PRA 2016/15819).

2015-16 Mercedes-Benz X166 GLS: loss of power steering assistance

In August 2017, a recall was issued for Mercedes-Benz X166 GLS vehicles that were available for sale prior to 1 August 2016. Due to an insufficiently sealed connector, moisture could enter the electric power steering control unit and interfere with signal transmission – this could cause a loss of power steering assistance and increase the risk of a collision. To fix, the connector was to be replaced (PRA 2017/16263).

2018 Mercedes-Benz X166 GLS: reduction in rear braking and increased brake pedal travel

In August 2018, recall campaign RC2555 was issued for Mercedes-Benz X166 GLS vehicles that were available for sale in Australia from 1 May 2018 to 23 August 2018. In these vehicles, hydrogen may have become embedded in the material of the pistons of a certain batch of brake callipers. This hydrogen could leak from the pistons and enter the hydraulic components of the rear axle brake and cause ‘compressibility’. As a result, the braking power of the rear wheels could be impaired and brake pedal travel could be extended. For the VINs of the recalled vehicles, please see PRA 2018/16989.

2016 Mercedes-Benz X166 GLS: fire hazard from oil contacting exhaust system

In September 2018, a recall was issued for Mercedes-Benz X166 GLS vehicles that were available for sale in Australia prior to 31 August 2016. Under ‘dynamic operating conditions’, oil foam could develop in the system’s oil reservoir if oil was below the minimum level. This could cause oil to escape via the ventilation bores in the cap of the reservoir and escaping oil could spray onto hot components parts of the exhaust system and cause a fire. For the VINs of the recalled vehicles, please see PRA 2018/16986.
