Bulletin Summary
TSB: ECU UPGRADE - STEERING LOGIC IMPROVEMENT - This bulletin has been revised to include additional information. This bulletin provides information related to the MDPS ECU software upgrade for some 2012-2014MY Optima (QF), produced from August 2, 2010 through July 27, 2014, and 2016-2018MY Sorento (UMa) vehicles, produced from October 27, 2014 through August 22, 2017, which may experience a notchy feel in the steering wheel. To correct this condition, the vehicle should be evaluated using the MDPS Effort Measurement Software detailed in the repair procedure starting on page 2 to determine whether an improved steering logic should be installed in the MDPS ECU, or if the Steering Column and Housing Assembly replacement is required.
About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
