I live in Florida and on August 17, 2023 I had to drive myself to Mease/Countryside Hospital, the heat index was 115 degrees, I had to get into my extremely hot vehicle. I was diagnosed with heat exhaustion. My bill was $ 23,000. I also have a grand baby I have to place in my very hot vehicle when I babysit. Three (3) windows do not function. On September 08, 2023, Hyundai of NPR Service Advisor gave me a ball park quote of $ 750.00, including labor to repair all three (3) windowsâ¦.I then made a formal complaint to the complaint number I found in my vehicle manual: Case Number [XXX] they did not help and referred me to the General Manager of the dealership.

The manufacturer is at fault, the window parts are defective! Please help me, my health has been affected and I hate putting my Grandchild [XXX] in unheathy environm
