• Recall 21V749000Sep 24, 2021469,377 vehicles
  ELECTRICAL SYSTEM:SOFTWARE · EXTERIOR LIGHTING:TURN SIGNAL

  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.

  Remedy: 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.

  Hyundai Motor America (Hyundai) is recalling certain 2017-2018 Sonata, 2016-2018 Sonata Hybrid, 2018-2020 Accent, and 2016-2017 Azera vehicles. The trunk latch may become damaged, preventing the opening of the trunk from the inside.

   I am reporting an unaddressed, critical safety defect involving the Theta II engine in my 2017 Hyundai Sonata. The engine has developed a severe internal metallic knocking noise consistent with connecting rod bearing failure—the exact manufacturing defect associated with Hyundai's major engine recall campaigns (such as Recall 198 / Campaign 966)

   I was driving down the road when my sunroof glass completely ripped away from the top and flew off. The glass is gone but the frame is still there but bent. I took it to a auto glass repair shop that stated "sunroof glass separated from urethane, came off and bent frame." I am dropping off at Hyundai dealership 9.17.26 to have them inspect. My insurance will not cover repairs. So I am hoping maybe this has happened to other people. There was a recall on sunroofs for the…

   The vehicle suffered a sudden, catastrophic internal mechanical engine failure out of nowhere without any warning lights or previous symptoms. An inspection of the engine cylinder revealed a physical hole blown through the top of the Cylinder 2 piston, causing immediate and complete loss of engine compression. This sudden structural failure caused the vehicle to completely lose all propulsion and stall unexpectedly while in operation, creating an immediate, severe safety…

   We had a recall done, Campaign 92C, and every since then the car drives horrible. It's worse when cool, it sputters, and hesitates especially when excellerating. Even after warmed up it seems to slam in and out of gear at low speeds, even when foot is not on the gas. The drive is choppy. The dealership told us to drive it and let the transmission "learn" our driving patterns, but it has not resolved itself. Before campaign car ran smooth, now shuttering and sputtering.

   I am writing to report a direct violation of the Theta II Class Action Settlement terms by Hyundai Motor America. This morning , I emailed an Executive Case Manager explicitly explaining that my 2017 Sonata has an active P1326 code, has the 2019 KSDS update, and requires a mandatory diagnostic under NHTSA Recall 17V226 that cannot be denied due to a salvage title. Instead of replying to my facts, the Case Manager Kathy gave me a hard denial falsely framing my federal recall…

   Driving home from work on [XXX] (not a safe location)when my car lost power and engine light began to flash. I pulled off to the side of road and called my dad. He came with a code reader and said there was a code P1326. He cleared the code and car drove normally again. 2 days later it began to run rough. I was told about the engine recall so I called Hyundai corporate and told them this same story. I was advised to take to dealership and have the “rod bearings inspected”…
