The air conditioner quits working after a few minutes if the temperature is over 80 degrees. This has happened multiple times, at least 6 times. I took the car into Hyundai dealer and they said they could fine nothing wrong with it. As soon as we got it back from the dealer it happened again. Heat stroke was our only safety concern. No warning light has ever come on to report this breakdown.

Leased a 2020 Santa Fe on April 24, 2020 and on July 9, 2020 it stalled and all the lights on my dashboard lit up like a christmas tree and after 20 mins. Was able to start it. The dealer said nothing wrong. In August 2020 the car wouldn't start, after a road side assistance jump the dealer said I'm not starting it enough. In October same thing happened I got a new battery from the dealer. In December the same thing happened I got another new battery. They refuse to admit something is drawing power from the battery in the off position. Instead they say I'm not starting the car enough. I start the car 2 to 3 a week.

With less than 1000 miles on the car, the horn stopped working intermittently. (the majority of the time it didn't.) the dealer kept the car for a week. The determination was that the "driver air bag clockspring has internal malfunction". the paperwork shows that it was replaced. Yesterday, approximately three weeks after the repair, the horn failed to work again while driving on the highway. (based on past experience, speed doesn't seem to be a factor.)

My husband and I purchased this car brand new, with only 252 miles on it. On the third day of owning it we were driving and within 5 miles the car began alarming with the center driver console indicating the engine was overheated. The temperature gauge was in the red zone. After a few seconds it dropped slightly and fluctuated in the upper 2/3S of the high temperature region. We drove to the dealership, which was within 10 miles. Once we were within half a mile the car engine began rattling every-time I tried to accelerate and the temperature gauge at this point remained in the redline. In addition, during all of this we turned the heat on to pull some heat from the engine but only cold air would blow. We were within the 3 day grace period of no questions asked return policy so we decided to return the call as it was brand new and had such a serious malfunction. We have not heard back from the dealership as to why the car malfunctioned.

Brake has been sticking last couple of weeks so that I had to pump brake to release to start. This morning I went out to the driveway and could not get into car with either remote or by using blue link on my phone. I used the manual key but could not release any other doors or lift gate. No lights, hazards, radio no nothing. I have had a few dead batteries and never had a car that dead overnight. I drove home from work previous night and I was outside after dark next to my car, no lights left on. I called roadside assistance, first guy said he thought there was a short, parking brake would not release and car still did not start. A different tow truck had to come with dollies and it was towed to the dealer. Dealer said it was a dead battery at 4918 miles! thankfully I was at home and the heat index was not at 105 degrees yet for the day.
