Bulletin Summary
Certain Elantra Hybrid (CN7 HEV) vehicles may exhibit an intermittent condition where the cruise control set speed could gradually increase when the driver releases the cruise control set speed adjustment switch. The cruise control set speed is clearly displayed on the instrument cluster, provides visual indication to the driver when the set speed is adjusted, and remains adjustable by the driver at all times. The cruise control can be cancelled by normal methods, either by pressing the cruise control switch or depressing the brake pedal. Follow the procedure in this bulletin to update the Hybrid Control Unit Low Voltage DC/DC Converter (HCULDC) system software to resolve this condition.
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.
