The vehicle is a 2023 Hyundai Santa Fe Plug-in hybrid. Purchased new in January 2024. It currently has 40,087 miles. My wife and I were traveling were traveling at the posted speed limit when we heard a loud bank. The operation of the vehicle was not effected. Upon inspection, we saw the the glass sun roof had blown out of the roof of the vehicle. We took the vehicle to the local Hyundai dealer for repair under the 5 yr 60,000 mile warranty. We were told it was not covered.

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,…

While on the highway my car lost power, gradually slowing down to a stall. I was able to safely park on the side of the road. I got the car to a nearby dealership that kept it for 10 days. The dealership said that the problem was code P2118 (Throttle Actuator Control Motor Current Range/Performance) that the air "flap" was frozen stuck shut and the engine was disabled on the freeway in order to prevent damage. The resolution was "waited for it to thaw and cleared the code". The dealer has a service bulletin and a software update but it did not resolve the safety issue. I've noticed hesitation when accelerating the car from a dead stop as well, which started last year.

While operating the vehicle, the cruise control turns off without any warning. The warning messages that come up only after the cruise control is turned off by the vehicle state "Smart cruise conditions not met" and "forward safety system disabled. Radar blocked". This disables the vehicle from utilizing cruise control in any manner. This happened on the highway with the cruise set at 72 mph, with a semi truck right behind my vehicle in moderate traffic! The semi slammed brakes on and after initial shock, I was able to accelerate the vehicle somewhat to avoid a collision. The dealership claims that "ALL" new vehicles do this when operated in wintery weather, snow, or mud kicked up from the…

Two issues with powertrain/transmission: 1- The powertrain/transmission fails intermittently- vehicle RPM goes sky high but vehicle receives no power, seems to fail/lose power. Has happened in very dangerous road conditions where unexpectedly was struggling to get the motor to engage/get power to the vehicle. Check engine and check hybrid system lights accompanies the problem. 2- The car should be driveable in electric only mode without use of gasoline. The powertrain/transmission seems to struggle to shift between electric and gas motors. HYUNDAI cannot seem to correctly diagnose or fix the issue. Does not seem they have proper diagnostic process included on the car- despite finding error…

>>>>What component or system failed or malfunctioned, and is it available for inspection upon request? According to the Hyundai Bluelink app, the problem is caused by the battery management system, producing error code P0AA600. The result is that the vehicle does not get power to the wheels for a few seconds after giving it gas. It looks like the car is not moving, then it very slowly gains speed, followed by sudden acceleration. It is available for inspection upon request. >>>>How was your safety or the safety of others put at risk? It is a safety issue because other vehicles on the road may not be able to stop in time when the car pauses unexpectedly. Also the driver cannot predict when…
