I was merging onto interstate traffic when the vehicle suddenly stuttered and decelerated. I managed to merge, then cross over several lanes of traffic and pulled over. Thought maybe a fuel problem (I had just filled the tank), or overheating. It only has 24K miles on it, and I've faithfully taken the vehicle to the dealer for regular service intervals, so I know it is not a fluid leak or problem. after a few minutes, I was able to start the car again, but it immediately shut down. Did this several times before giving up and calling for a tow truck. Had it towed to the dealer, and the next day they told me it needed a new engine, but the service department needed approval from corporate Hyundai. I'm waiting with baited breath.

What component or system failed or malfunctioned, and is it available for inspection upon request? Vehicle was running exceptionally well until a software update was applied at the dealership. Hyundai has no recalls / safety campaigns on file for my vehicle make and model and was adamant that no updates should have been applied. On or shortly after this time, vehicle performance became really poor. mpg per tank dropped to around 22 / 23 mpg highway (normally 27-29 mpg), acceleration performance was reduced, and it felt as thought vehicle had issues accelerating at time. Shifting on hills became an issue as well as the vehicle did not appear to properly shift into the next gear when necessary. I was notified after purchase of the vehicle that it should be parked outside of my garage due to possible fire concerns even though my vehicle was supposedly not affected. How was your safety or the safety of others put at risk" Lack of power / acceleration when needed affected getting onto the highway and shifting lanes. Vehicle rode almost like brake was being continuously applied and slowing down the vehicle at times. Lack of power and improper shifting almost caused an accident or two. Has the problem been reproduced or confirmed by a dealer or independent service center? No, dealer was unable to reproduce after a quick 10 minute test drive on flat land. I started keeping records and screenshots afterwards. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No. Hyundai refuses to contact me back regarding these issues. During this time, an email was sent globally indicating that Hyundai BlueLink would no longer support a feature that independently slowed / stopped vehicles in case of theft. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear" No warning lights have appeared on this vehicle.

Severe hesitation when attempting to accelerate from a stop. Car does not move, requires sveral attempts to press the accelerator before the car responds, extremely dangerous when entering an on ramp, merging onto a highway, or in heavy traffic. This has been an ongoing problem with this car, has not been rectified, Hyundai refuses to acknowledge the problem.
