Fortunately, Hyundai has initiated a recall, offering a free Anti-Theft Software Update and a steering wheel lock. The complainant verified with their Hyundai dealership in Oregon that their vehicle had already received the Anti-Theft Software Update. They became aware of this issue when their insurance provider, State Farm, canceled their policy approximately one month after the policy had been initiated.

I own a 2020 Hyundai Tucson Sport, and I’ve experienced a recurring issue. Whenever I’m driving on the highway for long distances, the forward collision warning system activates, even when there are no vehicles or objects in front of me. As a result, the SUV suddenly comes to a halt with a loud, startling noise. To address this, I have to pull over, turn off the vehicle, and then restart it because the RPM starts to increase. This situation is a significant safety concern, and I’m grateful that there were no vehicles behind me, as it could have led to a potentially dangerous situation on the highway.

We’ve owned our 2020 Hyundai Tucson for a little over three weeks now, and I must say it has been operating flawlessly. Everything functions perfectly, with no squeaks, rattles, or any imperfections to speak of. The seats are exceptionally comfortable, and the ‘Value’ option truly lives up to its name! We are thrilled with our purchase, and the Hyundai warranties, which were a significant factor in our decision-making, have left us extremely satisfied.
