There are warning lights saying the inverter coolant is low but the reservoir is at the proper level.  I suspect the coolant for the Hybrid charging inverter is bad and crystalizes causing blockages in the inverter coolant system.  My car refuses to charge for the last 2 years.  After a few seconds (about 7-10) the car shuts off the charging system when plugged in.  And now that summer heat us here in the South West, it will not even charge from the regenerative braking.  The high voltage battery previously would maintain 10-15% charge from the gas engine and regenerative braking. Now it's sitting at 1%.  Because the battery is so low the electric motor does not produce power, and the gas engine is under powered on its own. This makes acceleration from a stop light/sign sluggish, slow and dangerous.  Other Hyundai EV (IONIC and Kona) and PHEV (Santa Fe and Tucson) models have had their inverter coolant flushed and replace, some with a different spec coolant. This Sonata 2019 PHEV probably suffers from the same poor coolant and needs to be flushed and replaced by the better spec coolant fluid too.  This has been getting worse and worse the last 2 or 3 years.  The dealer refuses to acknowledge the problem and wants to diagnose the whole system before replacing what is obviously wrong first.  The inverter coolant low level alert comes on some times, but it is not low.  I haven't had time to let the dealer keep my car for days while they pretend to not know the problem and refuse to accept responsibility.  Hyundai Technical Service Bulletin (TSB) exist for IONIC, Kona, Santa Fe, and Tucson models. For example the Hybrid Santa Fe and Tucson TSB is Hyundai TSB 23-01-052H-1.","products":[{"type":"Vehicle","productYear":"2019","productMake":"HYUNDAI","productModel":"SONATA PLUG-IN HYBRID","manufacturer":"Hyundai Motor America"}]}]}
