Recalls and investigations
One recall on the electrical system covers the 2015 model year. A recall on the same system isn't always the same failure, so read the defect text.
Hyundai Motor America (Hyundai) is recalling certain model year 2015-2016 Sonata vehicles manufactured May 28, 2014, to August 21, 2015. The affected vehicles are equipped with an Antilock Braking System (ABS) warning light intended to warn the driver if there is an ABS malfunction. In the event of an ABS malfunction, the Brake System warning light will illuminate, but the ABS warning light will not illuminate. Since the vehicles have ABS malfunction lights that do not illuminate, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 135, "Light Vehicle Brake Systems."
Risk and remedy
Remedy: Hyundai will notify owners, and dealers will update the ABS control unit software, free of charge. The recall is expected began on November 30, 2015. Owners may contact Hyundai customer service at 1-855-671-3059. Hyundai's number for this recall is 134.

Should you keep driving it?
This page can't tell you that. 1 of 29 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
File your own report with NHTSA. Complaint counts are how a problem gets an investigation.
