2020 Hyundai Santa Fe Electrical System

Unknown Sometimes when i stop the vehicle the engine shuts off and wont come back on until i put the car in park and turn the ignition off. Not safe at all when your in heavy traffic

2020 Hyundai Santa Fe Limited AWD, VIN [XXX] , 30,000 miles. Air conditioning fails to blow cold air; climate control displays -10°F, indicating a defective evaporator temperature sensor per Hyundai TSB 21-HV-002H (2021). Dealer diagnosed evaporator/thermostat failure, quoted $2,500, despite TSB specifying a $30–$50 sensor replacement. Vehicle is 9 months past 5-year warranty but under 60,000 miles. This known defect causes driver discomfort and potential visibility issues (fogging in humid conditions). I have dash photos and dealer quote. Request NHTSA investigate for recall due to widespread HVAC issues in Hyundai models. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The backup camera will sometimes have black lines and flash off/on while in reverse. Other times, it will display a solid blue screen and the camera doesn't show an image at all. I took it to the dealer and since they weren't able to replicate the problem, they didn't look at it. I showed them a video I recorded, but that wasn't good enough. It's happening more often and seems to mostly occur after the vehicle has been parked outside.

******* DELETE VOQ ******* THIS COMPLAINT IS BEING MARKED FOR DELETION BECAUSE IT IS REQUESTED BY THE CONSUMER THAT THEY WISH TO HAVE IT REMOVED*DJR ******* DELETE VOQ *******

The contact owns a 2020 Hyundai Santa Fe. The contact stated that the vehicle alarm system failed to activate during a vehicle break-in. The vehicle was unoccupied at the time of the failure. A police report was filed. The dealer was notified of the failure and the contact was advised to contact the insurance company and an appointment was scheduled for the vehicle to be diagnosed. The vehicle was not diagnosed. The vehicle was not repaired. The manufacturer was notified of the failure and provided case number. The failure mileage was approximately 55,000.

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.

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.

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.)
