“From what I have been told there is no recall on this issue. Purchased a Hyundai Sante Fe Hybrid 2021 brand new in 2021. I live in La Quinta California summers are especially hot. Temps can be anywhere from 105 to 120 . Only had the car for 6months when in light came on saying Inverter needs coolant this has been a problem for the past 2yrs. Checked with Hyundai Service department my coolant is fine air conditioning works well. This not a safety issue but should be fixed and Hyundai is doing nothing about it. Many complaints have been ignored.”
NHTSA complaint #11521248, filed 2023-05“Having issues with the dash going completely black; so you can not see any instruments on the dash panel or the head unit (navigation/radio/airplay). The car has been into the shop three times so far with no resolution. The newest issue; the horn doesn't work, the safety features such as lane assist, lane departure etc. only work intermittently, and I have had the brakes slam on for no reason. The last time I took the car back to dealer and told them I was afraid to drive the car, the service manager changed the settings on the safety features, not sure how that was to fix anything? …”
NHTSA complaint #11489367, filed 2022-10“The vehicle has a wireless phone charger which causes the phone to overheat. It causes so much heat that the phone shuts down to prevent damage to the phone. There is a potential risk for fire.”
