2022 Hyundai Santa Fe Hybrid

While Driving home from work, the 2022 Hyundai Santa Fe Hybrid Vehicle's, Hybrid battery began to discharge rapidly, the Gasoline Engine did not start to charge the system, within 1/4 mile the Hybrid Battery fully discharged, and the Vehicle lost all acceleration , the Dash warning " CHECK HYBRID SYSTEM, STOP SAFELY " came on along with a loud audible warning beeping. I pulled off the road as soon as possiable. The Vehicle would not accelerate, and the gasoline engine part would not start. Several other warning lights illuminated, including the 12V battery low warning. I turned the Santa Fe off, and called Hyundai Roadside Assistance. While on the Phone with the assistant, as it was Night time, I couldn't see to check the VIN number for her I turned on the interior lights, then continued talking to the assistant. I attempted to restart the Vehicle , and it started the Gasoline Engine this time, we talked, and she suggested I see if the Hybrid Battery would now charge it's self, which it very slowly did up to 1/8 full, then I attempted to move the Vehicle to a safer location , a Gas station parking lot. I was able to drive the short 1/4 mile to the parking lot, but the vehicle had very little acceleration. Almost no power! At the parking lot I attempted to rev the engine to get more power to the Hybrid Battery, while waiting for a Tow Truck.

2022 Hyundai Santa Fe Hybrid. This incident has occurred twice at the time of this write up. Both incidents have happened on the first start up of the vehicle engine for the day in the early morning (on the way to work). The temperature outside was cool (10-35 degrees, Maine). On at least one occasion it had rained during the night before using the vehicle. It may have been damp on the other occasion as well. After about 3 miles of driving the vehicle it completely loses power. No amount of movement to the accelerator changes the sudden loss of all power. This is a hybrid and the battery gauge below charge/economy/power rpm area of the vehicle starts to completely and instantaneously drain to what would be zero had I not been able to pull the vehicle over and turn the vehicle off. At this point, on both occasions, leaving the vehicle turned off for a minute and then restarting the vehicle seems to alleviate the problem. The incidents have occurred about 2 months apart and since the vehicle turned 20,000 miles. I also feel like it takes more push on the accelerator to get the same response that I got on day 1 when I drove it off of the lot at the dealership. I also notice that the EV indicator light does not come on as frequently as it used to. It would always come on when coasting - and now sometimes it does not.

This vehicle is a Hybrid and the issue is an on/off error message that states that the inverter coolant level issue. When I lift the hood and view the inverter coolant level it is at the same location as the car was delivered in (exactly on the high mark). I have contacted two separate Hyundai dealerships in my area and one choose not to respond and the other stated that they were aware of this issue but had no fix for it. I tried to purchase the inverter coolant from the dealer and they do not even have it in stock to sell even if the coolant level was low. They have admitted that they do not know how to fix it or what is causing this issue. It is all over the forums and Hyundai is doing nothing to address it with anyone. I have a feeling that Hyundai does not know what the issue is and I know that they are aware and making no attempt to repair or replace it. If something is important enough to have a warning light go off shouldn't it be replaceable or repairable. These cars are put out so quickly and not enough testing and dealer personnel are not trained on how to troubleshoot or repair. I purchased the vehicle for cash and if Hyundai cannot fix it I believe I should be able to return it as a defect and get my money back.
