I recently blew out my front tire and put on the Hyundai supplied emergency spare. Within 15 minutes of driving, no more than 10 miles, I was flagged down by another driver because a huge cloud of smoke was coming from my car. I had the car towed into a dealership and they informed me that the spare tire that Hyundai supplied me damaged the transfer casing on the front tire, causing the smoke. I was told to never put that tire on the front of my car or it will again damage my car. I contacted first my local selling dealer. They were no help. They informed me that the spare tire was the correct part and I needed to contact Hyundai directly, which I did. After a week of investigation, [XXX], from their National Consumer Affairs department, indicates that Hyundai has essentially washed their hands of my problem and said it is the correct part and I should use that. I said it damaged my car and the response was it is only supposed to be on long enough to get to a repair shop. My car was overheating after only 10 miles. Smoke was coming from my car after 15 minutes. What if I was on a highway when the tire blew? It could be much longer than 10 miles. Would the car catch on fire? Will Hyundai take responsibility for the possibility of my car catching on fire? What about the dangers to myself and my family? Hyundai is taking no further action on this. I am to use the supplied part, damage, or no damage. INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

While driving up a steep mountain road in heavy traffic and snow the transmission on my Hyundai Kona overheated and failed. The car began to buck back and forth and a transmission light came on. Unfortunately I was on a mountain interstate in heavy traffic with no real shoulder due to snow. I attempted to limp the car to the top but moved towards the right lane in case. The transmission did it's bucking thing 3 times total and then I noticed smoke coming from the powertrain area. At this point I pulled over and put my car basically into a snow bank so as not to get run over by semi trucks. I called AAA but was able to get the car up the hill after letting the transmission cool for around an hour. This entire situation was completely unsafe and had I been informed I would not have purchased the car because I know that I spend most of the winter in traffic on a mountain interstate. What's even more concerning, this issue is documented heavily online yet the sales reps for Hyundai are not aware. The service department is aware and told me that they couldn't do anything because it was working as it is designed. See here an additional forum which outlines the same issue for another driver. https://www.hyundaikonaforum.com/threads/dct-shifting-annoyances.2428/ Best, Greg

While driving to work car started knocking. As soon as i arrived not even 5 miles from my home, died in my parking lot. Car had no indications of issues. Only information was due for oil change. Checked oil there was none. I was taking it in for service the next day for my regular service check. I was 62 miles over the standard time. Had to pay a tow and found out there is a hole in my engine block. Well with no indication of "Low oil" this brings a question of a information failure>?

I’ve had this car since end of September 2021. The blind spot monitor on the right side of the vehicle lights up and beeps at random times, even when there is nothing in the blind spot itself. Happens mostly while driving on the highway.

Had I been on the bridge when the engine seized it would have meant imminent death. The Hyundai dealership said they expected it because engines on the 2021 Hyundai Kona have been recalled. This vehicle was supposed to be fitted with a safety light warning the driver of an imminent fire or engine failure after 2019 but that didn’t happen.

Hyundai Motor America (Hyundai) is recalling certain 2019-2020 Elantra, 2019-2021 Kona and Veloster vehicles equipped with 2.0L Nu MPI engines. The piston oil rings may not have been properly heat-treated, which could result in engine damage.
Consequence & remedy
Consequence: A damaged engine may stall, increasing the risk of a crash. In addition, oil may leak onto hot exhaust components, increasing the risk of a fire.
Remedy: Dealers will inspect and, if necessary, replace the engine, free of charge. In addition, Hyundai will deploy Piston Ring Noise Sensing System (PNSS) software. Owner notification letters were mailed August 24, 2021. Owners may contact Hyundai customer service at 1-855-371-9460.
