The NX, an important model for Lexus here, is said to suffer from an automatic brake-hold programming issue, which disengages the brake-hold feature in specific situations (like when the driver undoes his seatbelt, or example). This could, naturally, cause the vehicle to roll unintentionally, which poses an accident risk.
The brake hold function was designed to deactivate, and warn the driver should his/her seatbelt be unfastened. However, as the brake hold function disengages, the parking brake should then automatically be applied to mitigate the risk of rolling. It seems that this particular function is not currently performing as it should be.
Lexus Australia has said that no cases of unintentional rolling has been reported in our market. The NX models affected were built from 2014 through to 2016, and their vehicle identification (VIN) numbers can be viewed here.
Owners will be contacted by Lexus Australia themselves, though we advise affected NX drivers to get in touch with their local dealership at the soonest possible convenience to have their electronic skid control unit (which handles the brakes) reprogrammed. The fix should take about an hour. Any and all queries on the matter can be directed to Lexus’ customer assistance line at 1-800-023-009.
