When owners reported it
Related recalls (6)
Electrical system: instrument cluster/panel
Model years: 2026
Problem: Hyundai Motor America (Hyundai) is recalling certain 2025-2026 Tucson Hybrid, Tucson Plug-In Hybrid Electric (PHEV), 2026 IONIQ 5, Santa Cruz, Kona, Palisade, Palisade Hybrid, Santa Fe, Santa Fe Hybrid, Sonata, Sonata Hybrid, and Tucson vehicles. Due to a software error, the instrument panel display may fail. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 101, "Controls and Displays."
Risk: An instrument panel display that fails to show critical safety information, such as the speedometer or warning lights, increases the risk of a crash.
Fix: The instrument panel display software will be updated over-the-air (OTA) or by a dealer, free of charge. Owner notification letters were mailed March 24, 2026. Owners may contact Hyundai's customer service at 855-371-9460. Hyundai's number for this recall is 293. Vehicle Identification Numbers (VINs) involved in this recall became searchable on NHTSA.gov on January 28, 2026.
Electrical system:software; exterior lighting:turn signal
Model years: 2015, 2016, 2017
Problem: Hyundai Motor America (Hyundai) is recalling certain 2015-2017 Sonata, 2016-2017 Sonata Hybrid, and Sonata Plug-In Hybrid vehicles. The Smart Junction Box (SJB) software logic may not properly interpret the signals received from the multifunction switch, which could cause the turn signal to activate in the opposite direction of what the driver intended.
Risk: A turn signal that activates in the opposite direction of what was intended by the driver increases the risk of a crash.
Fix: Dealers will update the SJB software, free of charge. Owner notification letters were mailed November 19, 2021. Owners may contact Hyundai customer service at 1-855-371-9460. Hyundai's number for this recall is 210.
Electrical system:software
Model years: 2020
Problem: Hyundai Motor America (Hyundai) is recalling certain 2020 Nexo and Sonata vehicles. The Remote Smart Parking Assist (RSPA) software may fail to prevent vehicle movement upon detection of an RSPA system malfunction.
Risk: Unintended vehicle movement increases the risk of a crash.
Fix: Hyundai will notify owners, and dealers will reprogram the RSPA software, free of charge. The recall began June 3, 2020. Owners may contact Hyundai customer service at 1-855-371-9460. Hyundai's number for this recall is 191.
Electrical system: instrument cluster/panel
Model years: 2015, 2016
Problem: 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: If the driver is alerted there is a brake system malfunction, but not specifically with the ABS system, the driver may operate the vehicle unaware that the vehicle's brakes may lock up during hard braking, increasing the risk of a crash.
Fix: 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.
Electrical system:wiring; steeringDo not drive
Model years: 2015
Problem: Hyundai Motor Company (Hyundai) is recalling certain model year 2015 Sonata vehicles manufactured May 2, 2014, through May 23, 2014. A poor connection within the vehicle's wiring harness may result in a reduction of steering assist from the vehicle's motor driven power steering system or the inability to move the vehicle's shifter from the Park position.
Risk: The reduction of power steering assist can increase the steering effort needed, increasing the risk of a crash.
Fix: Hyundai notified dealers to suspend sales of affected Sonata vehicles and has published recall bulletin 14-01-024 providing a service procedure to repair the affected vehicles. On June 7, 2014 Hyundai began to contact the affected retail customers. Owners may contact Hyundai customer service at 1-800-633-5151. Hyundai's number for this recall is 119.

Risk: This condition can cause the engine to stall, increasing the risk of a crash.
Fix: Dealers will re-route the maf sensor connector wiring harness.
