2023 Hyundai Santa Fe PLUG-IN Hybrid

The fuel range calculation is often very wrong in our plug in hybrid. This issue has been brought to the attention of the manufacturer and dealer with no results but pointing at the other organizations. With a full fuel tank the gasoline range should be about 387 miles. Often the computer will show 610 miles but sometimes has other ranges but has never been correct after the first fill up. While this normally isn't a big problem, there is a danger for some people. Say you see a sign on a curvy mountain road with no shoulders showing the next fuel is in 100 miles. If the car computer says you have a range of 150 miles, you would think you can easily make it to the next gas station. However, because of the computer error, you really only have a range of 95 miles. It is probable that you would run out of fuel, losing power steering and power brakes. Additionally you could end up stopped blocking the lane and causing a collision. This has been occurring for three years, ever since our first fill up of the gas tank.

The rear section of panoramic sunroof exploded. We were traveling approximately 60 MPH on HWY 395 crossing the bridge on the Columbia River between WA and OR. Suddenly we heard a very loud explosion. When we stopped to investigate we found a hole in the sunroof. It exploded up and outward. There were very few glass shards inside the vehicle and no debris or evidence of anything that could have caused the breakage. The Hyundai dealer was unwilling to repair it as a warranty item. We paid a glass company through our insurance company to replace the glass. I’m aware that there were problems a few years ago with the Hyundai sunroofs and was advised to file this incident report. It was extremely scary to experience the noise.
