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.

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? We have been so close to being rear-ended because of the faulty braking system. The electrical system is having major issues, I have videos of the car doing all these things and have showed them to the dealership and they claim they can not fix the car because it doesn't happen when they drive the car.

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.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2021 Hyundai Santa Fe Hybrid Hev verdict →
