2019 Hyundai Santa Fe Electrical System Problems

This car has been cutting off for a month and no type of codes popping up alternator has been replaced two brand new batteries has been replaced which is dangers car cutting off while I am driving this vehicle is not safe at all needs to be recalled asap mechanic can’t even find the problem .

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.

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 with me that repeated activation of the ISG was the likely cause of the starter short, they wouldn't put that in the written service statement. At the time of this problem, my Santa Fe was 1,887 miles past the 5-year 60,000 mile bumper-to-bumper warranty. I had purchased the Santa Fe a few months ago as certified pre-owned with about 58,500 miles on it so, even though being the 2nd owner, I retained the remainder of the bumper-to-bumper warranty as well as the 10 year 100,000 engine/drivetrain/transmission warranty. Oddly enough the starter, which is attached to the engine is categorized as part of the car's electrical system instead of as part of the engine so the starter replacement wasn't covered. I appealed to the dealer for a discount of some kind. They declined. They claimed to have called Hyundai USA which also supposedly said no to covering the cost of the new starter. A quick Google search for this problem revealed other owners of Santa Fes with the ISG have had the same exact issue.

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.

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

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.

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.

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

These Hyundai's & Kia's are being stolen left & right across the nation....Hyundai needs to fix our vehicle with an alarm system. We haven't heard anything!!! We owe on the car and if it gets stolen or ruined, we still will have to pay on this vehicle. Also, on top of it all, it will be ruined; and from what we see on TV, they can't even get the parts to fix them. Our SUV is not worth anything now due to those stealing these vehicles because of the Tic Toc videos. Those videos should be banned anyway and taken off so no one else can learn to do this horrible theft. If we can ever get another vehicle, it won't be a Hyundai. This has made us very upset that we haven't heard anything from Hyundai nor there seems to be nothing happening regarding this issue. Why isn't the government pressuring this company? We don't see anything being done.

The contact owns a 2019 Hyundai Santa Fe. The contact stated that while operating the vehicle there were multiple warning messages displayed on the instrument panel and the vehicle would not accelerate to exceed 10 MPH. The vehicle was towed to an independent mechanic who disconnected the battery and reset the computer and the failure was remedied. The cause of the failure was not determined. The local dealer and manufacturer were not notified of the failure. The failure mileage was 42,000.

STOPPED THE CAR AT A RED LIGHT AND THE IDLE STOP AND GO (ISG) FEATURE HAS TURNED OFF THE ENGINE... ONCE THE GREEN LIGHT TURNED ON, I PRESSED GAS AND THE ENGINE DID NOT START AND AFTER COUPLE OF ATTEMPTS ALL WARNING LIGHTS TURNED ON AND I WAS NOT ABLE TO USE THE KEY TO START THE ENGINE ASWELL. AND SO I HAD TO TURN OFF THE KEY COMPLETELY AND THEN START THE ENGINE... BOUGHT THE CERTIFIED PRE-OWNED CAR AT 38000 MILES IN FEB 2020 AND THIS HAPPENED ONLY ONCE IN AUGUST 2020 AND THE MILEAGE WAS ABOUT 39800 DURING THAT TIME. LUCKILY I HAD ONLY ONE CAR AT MY BACK WHO HONKED ON ME CONTINUOUSLY... I WAS NOT ABLE TO REPRODUCE THE ISSUE AFTERWARDS BUT TO BE HONEST I KEPT ONLY ABOUT 50 MILES SINCE THEN. I AM AFRAID IF I WOULD GET STALLED ONE FINE DAY... AND ALSO AFRAID HYUNDAI SERVICE CENTER WOULD JUST SAY NOT REPRODUCIBLE AND MAY JUST SAY TO TURN OFF THE FEATURE MAY BE?

AFTER DRIVING MY SANTE FE FOR LITTLE OVER 1000 MILES, I WAS WAITING BEHIND SEVERAL VEHICLES AT A STOP LIGHT IN HYATTSVILLE AND MY VEHICLE SHUT OFF AND WOULDN'T START. AFTER TRYING TO RESTART THE VEHICLE FOR MORE THAN 15 MINUTES, IT FINALLY STARTED. I DROVE TO THE NEXT STOP LIGHT AND HAD TO STOP AND THE VEHICLE FAILED TO RESTART. THIS HAPPEN TWO MORE TIMES AND THEN FINALLY IT STARTED AND I DROVE BACK TO THE DEALERSHIP IN GAITHERSBURG (FITZGERALD AUTO MALL). I REPORTED THE INCIDENT AND THEY CLAIM TO BE UNABLE TO RECAPITULATE THE INCIDENCE. AT AROUND 5014 MILES, WHEN I CAME TO A STOP LIGHT IN DC, THE VEHICLE SHUT OFF AGAIN AND WOULD RESTART. THE COPS CAME AND PUSH ME OUT OF THE ROAD AND I WAS THEN ABLE TO RESTART. I DROVE TO THE NEXT STOP LIGHT AND THE VEHICLE SHUT OFF AGAIN AND WOULD START. EVENTUALLY, THE VEHICLE STARTED AFTER APPROXIMATELY 10 MINUTES. I DROVE THE VEHICLE BACK TO THE DEALER AND WAS TOLD THAT THERE WAS A PERFORMANCE RECALL ON THE VEHICLE. THE VEHICLE WAS SERVICE AND GIVEN BACK TO ME. THE FOLLOWING DAY DRIVING ON GERMANTOWN ROAD THE VEHICLE SHUT OFF AGAIN AT A STOP LIGHT. I CALL THE DEALER AND THEY ASKED THAT I TAKE IT BACK THE NEXT DAY. ON MY WAY TO THE DEALER IN BUMPER TO BUMPER TRAFFIC THE VEHICLE SHUT OFF AGAIN. I TOOK BACK THE VEHICLE TO THE DEALER AND TOLD THEM THAT I HAVE NO CONFIDENCE IN THE VEHICLE ANYMORE AND THEY SHOULD REPLACE IT. THE MATTER WAS REPORTED TO THE MANUFACTURER WHO REFUSE TO REPLACE THE VEHICLE AND OFFER $500 COMPENSATION FOR MY INCONVENIENCE WHICH I REFUSE TO ACCEPT. I AM SEEKING YOUR ASSISTANCE TO THIS ISSUE. P.S. I DO HAVE PICTURE OF THE INFORMATION THAT WAS DISPLAYED ON THE DASHBOARD AT THE TIME OF THE INCIDENCE AND MY NIECE WAS WITH ME ON TWO OF THOSE OCCASIONS.

ON A BRAND NEW 2019 HYUNDAI SANTA FE, THE ENGINE STALLED TWICE WHILE DRIVING THE VEHICLE AT LOW SPEEDS INTO/OUT OF A PARALLEL PARKING SPACE ON A VILLAGE STREET. I HAD TO RESTART THE ENGINE IN ORDER TO CONTINUE MANEUVERING THE VEHICLE. THIS WAS VERY DANGEROUS AS I COULD HAVE BEEN HIT BY ONCOMING TRAFFIC.

TL* THE CONTACT OWNS A 2019 HYUNDAI SANTA FE. THE CONTACT STATED THAT THE VEHICLE'S SMART SYSTEM CAUSED THE VEHICLE TO BRAKE ON ITS OWN. ALSO, THE LANE CHANGE WAS NOT READING CORRECTLY AND PUSHED THE VEHICLE INTO THE WRONG LANE INTO A BARRIER. IN ADDITION, WHILE DEPRESSING THE BRAKE PEDAL, THE VEHICLE FAILED TO SLOW DOWN WHEN MAKING A RIGHT TURN. AFTER COMPLETING THE TURN, THE CONTACT WAS ABLE TO BRAKE. THE VEHICLE WAS TAKEN TO FITZGERALD HYUNDAI ROCKVILLE (11411 ROCKVILLE PIKE, ROCKVILLE, MD 20852, (301) 881-4000) TWICE WHERE IT WAS DIAGNOSED THAT THE SYSTEM WAS NOT CALIBRATING PROPERLY AND THE EASY PASS INTERFERED WITH THE SMART SYSTEM. THE EASY PASS WAS MOVED AWAY FROM THE CAMERA, BUT THE FAILURE RECURRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE AND PROVIDED CASE NUMBER: 16086926. THE VEHICLE WAS NOT REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 3,000. THE VIN WAS NOT AVAILABLE.

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 MARCH 31, 2019. THESE 2019 SANTA FE ARE NOT SAFE TO BE SELLING TO THE PUBLIC WITH THIS KNOWN DEFECT.

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 IS LIKELY TO INACCURATE. I OWN THREE HYUNDAI'S AND BUYING THE 2019 WAS A MISTAKE. THE BLUE LINK SYSTEM IS A MESS. THE SELL YOU THE SYSTEM IT WORKS ON YOUR PHONE, WORKS FROM ANYWHERE NO DISTANCE LIMITATIONS ECT. BUT AFTER YOU BUY IT THEY POINT OUT THAT YOU CANT COMPLAIN BECAUSE ITS A COMPLEMENTARY SERVICE. THIS ONLY COMES OUT AFTER YOU BUY THE CAR. THEY NEVER TALK ABOUT IT BEFORE THE PURCHASE. AFTER OWNING HYUNDAI'S FOR SEVERAL YEARS (3 OF THEM) I AM BEYOND DISAPPOINTED THEY THE CUSTOMER SERVICE IS SO POOR. WHATS WORSE IS THAT WHEN YOU COMPLAIN THEY CAN'T FIND A NUMBER TO CONTACT WHERE YOU CAN GET HYUNDAI AMERICA TO EVEN LISTEN TO THE PROBLEM.

MY NEW 2019 HYUNDAI SANTE FE FROM THE TIME I BOUGHT IT HAD THE YELLOW CHECK ENGINE LIGHT COME ON. IT SAID THE BSM SYSTEM WASN'T WORKING. THEN THE ENGINE WOULD NOT START ON 4 SEPARATE OCCASIONS. I HAD TO WAIT TO GET IT TO START. THERE HAVE BEEN 3 OCCASIONS WHEN IT DID START IT SOUNDED LIKE IT WAS GOING DIE, VERY SLUGGISH AND DIDN'T WANT TO ACCELERATE. THE RPM WOULD NOT INCREASE. IT ALSO STARTED 2 SEPARATE OCCASIONS IT LOST STEERING WHEEL POWER AND THE A/C STOPPED BLOWING COLD AIR. I HAD TO TURN IT OFF AND WAIT TO RESTART IT. IT IS CURRENTLY AT THE DEALERSHIP WAITING FOR THE BLIND SPOT MONITORING MODULES. THE FIRST TIME THEY REPLACED THE MODULE IT STILL SHOWED IT NOT WORKING. SO NOW IT IS UNDRIVABLE AT GENE MESSER HYUNDAI IN LUBBOCK TEXAS, THEY SAY IT'S NOT SAFE TO DRIVE SO I AM DRIVING A LOANER. THEY SAY THEY CAN'T DETERMINE WHY THE ENGINE DID THE DESCRIBED THINGS ABOVE. THESE THINGS HAPPENED WHILE IN MOTION AND PARKED.
