2021 Hyundai Santa Fe Hybrid

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.

Whenever the weather gets above 80 degrees outside my car put a notice to refill inverter coolant, when everything is filled max line. I’ve mentioned it twice to the Hyundai service and both times the employee told me not to worry about it and it is a sensor issue. That is unacceptable, I live in Las Vegas, Nevada where temperatures on average in summer are 90+. That’s a big risk an unnecessary danger to have my car engine over heat and stop in the middle of no where and potentially leave me stranded or worse cause an accident or fire. On top of that I have to see the message every day in the summer temperatures, without any way to remove the message. This will be the 2nd summer I’ve seen this message appear in my car, and I’m tired of the dealership & their car service staff telling me this is nothing to worry about… especially on car not even 4 years old!

On December 28, 2022, we were driving 70 miles per hour on Route 75 in the third lane of a four-lane highway from Michigan to Tennessee. In Ohio, the vehicle lost all drive power without warning. As it decelerated, we were able to maneuver the vehicle to the breakdown lane, narrowly avoiding other vehicles around us driving at 70 miles per hour. We do not know what caused this to happen. After several hours on the side of the highway, the vehicle was towed to Jeff Wyler Hyundai in Fairfield, Ohio. They have not been able to diagnose the problem as of today. The contact stated that the cause of the issue was due to an oil plug that was improperly tightened by the dealership during service maintenance. As a result of that, the oil was able to drain out and cause the engine to fail.

Refill inverter coolant comes up on my dash daily. I have taken the vehicle back to the dealership several times to get that serviced. After having the vehicle all day they tell me everything is running fine and they can’t find the problem or figure out why the message is coming up. This has been going on since I bought the vehicle in April. They assure me the vehicle is safe to drive and this won’t affect the vehicle in any way. This problem has not been resolved and I’m afraid serious damage will happen if this message keeps coming up and they don’t get it fixed.

I purchased my car in May 2021. Shortly after purchase, I noticed a "clicking" sound under the car when the car was operating between 15 and 20 MPH. I took the car to the dealer, who couldn't identify what was causing the sound. The dealer subsequently replaced the front axle, but the clicking sound continued, only audible when the car was moving at between 15 and 20 MPH. On June 9, I was driving at about 40 MPH on an interstate that had only a few cars on it. I didn't notice any debris or objects in the road, nor did I feel the car hit any debris or objects. Suddenly, I heard a loud "crunching" sound that I mistook for interference from the radio. I turned the radio off and realized the sound was coming from the rear passenger side of the car. I looked at the dashboard and saw the tire pressure light had illuminated. A few seconds later, the triangular danger sign also illuminated. I got off the highway at the next exit and stopped the car as soon as it was safe. The car made a lot of noise as I drove down the exit ramp, and it was difficult to steer, so I knew that the rear tire was flat. I got out of the car and found, to my surprise, that both tires on the passenger side were flat. The rear tire was cracked and ripped apart. The front tire was intact, but completely flat. The car has not been inspected yet, so I don't know what caused both tires to flatten at the same time. If I'd hit something hard enough to flatten both tires, I'd think I would have seen or felt it. My concern is that a defect in the tires related to the mysterious clicking sound that the mechanics could not diagnose caused the tires to blow out without warning at the same time.
