2019 HYUNDAI SANTA FE Electrical System Problems

I purchased my 2019 Hyundai Santa Fe on October 29, 2021. Since then, I’ve experienced a series of mechanical and electrical failures that I believe are far beyond normal for a vehicle of this age. - The remote start has never worked. - On October 20, 2023, the hatch latch failed. The only way to open it now is by climbing into the back and manually pulling the latch. - On October 27, 2023, the electric power steering failed. I had to replace the entire steering column at a cost of $4,000. - The paint began deteriorating prematurely and required a full repair. Hyundai covered this under warranty, but the cost was $8,000. - In early spring 2025, all coil packs had to be replaced due to misfires, costing approximately $500. - September 4, 2025, The car stalled while I was driving on a main road and I had to...

The contact owns a 2019 Hyundai Santa Fe. The contact stated that while attempting to accelerate from a stoplight, the vehicle failed to respond. The Auto START/STOP feature failed to restart the engine as designed. The contact stated that the Turbo light was illuminated as if the turbo was activated, even though the contact had not activated the feature. The vehicle was taken to a Certified mechanic who determined that the turbo had failed. The turbocharger was replaced. After the vehicle was repaired, the failure reoccurred while the vehicle was idling or parked. There were no warning lights illuminated. The dealer was informed of the failure however, the vehicle was not taken to be diagnosed or repaired. The manufacturer was informed of the failure and referred the contact to the dealer for assistance. The failure mileage was 90,000.

Continuous issue of front driver passenger power seat front level button failure. Continuous Headlights, fog lights getting fused every 4 months. Indoor back roof light works and sometime just does not work for months.

For the past month my car has been stalling in traffic. The car stalls and then turns back on a few seconds later. It also stalls when I am accelerating after stopping for a red light. This situation is very dangerous and it means that I cannot drive my car expecting to be safe at all. It seems like the motor and the transmission are involved which makes the stalling very dangerous as those are major systems.

Fire while driving - Electrical - No Warnings Reference NHTSA Recall 23V181000 Fire Extinguished once by fire extinguisher (civilian) then again by Union, MO fire department. Hyundai had the vehicle towed to their inspection facility. Inspection report being withheld. Claim has been denied. Hyundai now refusing to return vehicle.

My Santa Fe developed difficulty starting beginning the afternoon of February 18. While waiting in stop-and-go traffic to park for a sporting event, the ISG (idle stop-and-go) activated at least 40 times. After at least the 40th time, the Santa Fe did not turn back on. After about 10 minutes, I was able to start it. This happened while I was stuck in very heavy traffic exiting the freeway. After that, it would always take multiple attempts to start the car even though the battery had more than enough power to turn over the starter. After a couple of days of dealing with this, I took the Santa Fe to my local Hyundai dealer. After diagnostics, they were able to reproduce the problem and they determined that the starter had developed an intermittent short which was likely caused by the multiple ISG activations on Sunday, 2/18/2024. While they verbally agreed...

At various times the vehicle will not start. It takes multi times to to start the vehicle. The starter and battery have been tested and both are in excellent condition. Both key phob batteries have been replaced and the vehicle at times won’t start but the dash lights turn on. After twice of trying to start the breaks get really stiff. I’ve learned if I get out of the vehicle and open the hood and close it the car will start then any other time getting out and back in it does not start. I even placed the key phob in the designated location of the battery died and still won’t start. The check engine is not on either.

The Airbag light keeps coming on and saying it’s not activated, the wiring also keeps blowing out brand new headlights due to faulty wiring.

the systems forward collision and lane departure warning are randomly turned off. Dealership is not aware of how to fix

Adaptive Cruise Control Automatic Emergency Braking Blind Spot Warning Forward Collision Warning Lane Departure Warning Lane Keeping Assistance Parking Collision Warning Rear Cross Traffic Warning Every one of these lights are going off in the car. I’ve taken it twice to the Hyundai dealership. Both times they have not been able to figure out what is wrong with it even with the OPD it’s not showing any issues or fault codes a technician has even had the car for one week went through every single sensor, cable, battery, alternator fuses and didn’t come up with any results. He returned the car back to me completely baffled and unable to fix the issue. Please email at[ XXX] For photos and video which I cannot add here on this website through mobile. INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

The forward collision avoidance system is malfunctioning and shuts down the traction and stability control systems making the vehicle more vulnerable to collisions. Multiple attempts to repair this system have been unsuccessful

2019 Hyundai Santa fe first owner after each use of the Auto Stop/ Start feature is guaranteed that in 24-48 hrs the car will stall at stop lights and take anywhere from 15-20 min to restart. The power to the electronics continues but the engine can't restart from the stop. It appears as of the feature takes the power from the alternator, starter and battery and drains it until the car can be restarted. Once it starts it drives well until the system is engaged again. I have chosen to not use the system and the car has not stall however once the use of the Auto/ Start Stop system is engaged for a day or two it will stall the vehicle from a stop mostly at stop lights after so much time on standby mode while using the Auto Start / Stop system. Dealer can not recreate the issue.

The local dealer and manufacturer were not notified of the failure. The failure mileage was 42,000.

THE BLUE LINK REMOTE START OFTEN DOES NOT RESPOND. THIS IS VERY DIFFICULT TO GET FIXED. THE DEALER DOES NOT HAVE ACCESS TO THIS SYSTEM. HYUNDAI DOES NOT HAVE A CONTACT NUMBER THAT IS EASY TO LOCATE. WHEN YOU DO CALL THEY ARE DIFFICULT TO TALK WITH AND OFTEN JUST HANG UP ON YOU. THIS HAS BEEN AN ONGOING STRUGGLE FOR SEVERAL MONTHS. IT IS ALMOST IMPOSSIBLE TO REACH SOMEONE TO TALK TOO ABOUT THIS. THEY HAVE RECENTLY SENT AN E MAIL TELLING ME THAT THAT I MUST ACCEPT CHANGES IN MY BLUE LINK (THEY ARE GOING TO SHARE DATA FROM THAT WITH OTHER COMPANIES). YOU DO NOT HAVE AN OPTION TO DECLINE. THEY GIVE YOU AN OPTION TO AGREE OR THEY NOTE THAT CONTINUED USE OF BLUE LINK GIVES CONSENT. I DO NOT GIVE MY CONSENT. BLUE LINK IS NOT DEPENDABLE AND AS A RESULT DATA FROM THAT SYSTEM...

ON MARCH 5, THIS VEHICLE STOPPED WHILE DRIVING IN THE MIDDLE OF A STREET. I WAS UNABLE TO START THE VEHICLE AND ME AND MY PASSENGER COULD HAVE BEEN SERIOUSLY INJURED OR KILLED. CAR WAS TOWED TO DEALERSHIP AND HAS 2600 MILES ON IT. I HAVE FOUND THAT HYUNDAI IS DOING A RECALL TO REPLACE STARTER AND A SOFTWARE UPDATE. I HAVE BEEN TOLD THAT BECAUSE OF THE NEW TECHNOLOGY THIS VEHICLE HAS WHICH IS AN AUTOMATIC START AND STOP AT A STOP SIGN OR STOP LIGHT THAT THE STARTER SHORTED OUT AND APPARENTLY THE SOFTWARE IN THE CAR JUST STOPS THE CAR WHILE DRIVING.. THIS HAPPENED WHILE DRIVING THE CAR AT 35 MILES/HOUR ON A BUSY STREET. IT IS A MIRACLE THAT I WAS NOT HIT AND INJURED OR KILLED. CAR IS AT THE DEALERSHIP WAITING FOR A NEW STARTER AND SOFTWARE UPDATE WITH A POSSIBLE SHIP DATE OF...
