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.
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. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 401, "Internal Trunk Release."
Hyundai Motor Company (Hyundai) is recalling certain model year 2017 Hyundai Elantra vehicles manufactured April 15, 2016, to September 13, 2016, and Sonata vehicles manufactured May 27, 2016 to September 16, 2016. In these vehicles, the end seal for the driver's frontal air bag inflator may not have been properly installed, possibly resulting in reduced inflation of the frontal air bag in the event of a crash.
Complaints are unverified owner reports to NHTSA and are not normalized for sales volume. One complaint can cite several components.

“On the morning of XXX, when starting my vehicle, I noticed that the oil warning light was flashing. The outside temperature was in the low 40s, which immediately raised concerns about the vehicle's engine and oil pressure. I promptly shut off the engine and checked the oil level. The oil level was full, as I expected, because I had checked it the previous day. I have consistently paid close attention to the oil level in this vehicle because it has consumed oil throughout the entire time I have owned it, beginning shortly after I purchased it brand new. Due to this ongoing issue, I make it a point to keep extra engine oil in my trunk so I can monitor and maintain the proper oil level. On XXXX, I stopped by the Joe Holland Hyundai Service Department and spoke with [XXX] about the oil warning light continuing to flicker while driving. Unfortunately, no resolution or explanation was provided. However, [XXX] did acknowledge that the engine in my vehicle had previously been identified on a problem list due to a machining error that occurred during the engine manufacturing process. This acknowledgment is particularly concerning because it suggests that Hyundai was…”
“I was driving and all of a sudden the traction lights turned on and the sterring wheel is hard to turn. Almost go in a car accident. The windows just stopped working and the brakes light constantly keep getting burned out.”
“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 safety request as a "voluntary goodwill warranty" issue to justify her rejection. Please help me in getting authorization my car with Hyundai dealership in Plano Tx to run the bearing rod test and get it fixed.”
