My 2016 plug in hybrid Sonata repeatedly inidcates that there is "high system temperature switching to hybrid mode." This first happened on my first long trip in the car in 10/21 and has happened repeatedly since. This happens at all temperatures, including moderate temperatures (mid 70s). It seems to happen randomly, such as when battery has several miles of charge left in it, when it is fully discharged, and repeatedly when the car is already running in hybrid mode, which a driver could interpret means that the engine is about to shut down, as I did on a long trip. I have taken it to two separate dealers, and the only thing they did was replace the fuel pump, which did not solve the problem. In addition, the battery life has reduced greatly, despite the fact that I always fully discharge and recharge the batter. As you can see from the attached Hyundai forum comments, this appears to be a prevalent problem for this make and model car and no relief from the manufacturer appears

In January of 2022, my vehicle experienced a complete power loss while driving to work, leaving the car coasting down the road. A Check Hybrid System warning came up on the dashboard, along with several other warning lights, including Check Engine. Luckily, I was able to pull over without an accident occurring. Once stopped, the vehicle did restart and got me to and back from work. A diagnosis effort made at a local Hyundai dealership was unsuccessful as they could not replicate the problem and found no error codes in the auto's CPU system. I continued to drive the vehicle, hoping it was a one time deal, but since then, the identical situation has occurred three more times. I was extremely lucky that I had been in a position to safely pull off to the side of the road. The car has not been driven since March 19, 2022. After researching this scenario online, it appears to be the exact situation reflected in the Hyundai Recall campaign 175 from 2018, where the dealership remove the origi

This is a plug-in hybrid. Charging light on the dash blinks red indicating there is an issue (per manual). Also blinks while driving. Should be green. Still charges. Taken to two Hyundai dealerships. Computer produces no codes. Dealership does not know how to proceed. Safety concern is it’s unknown if battery is dangerous to charge? Is it dangerous to drive? How does a car indicate a problem but then give no codes.
