2019 Hyundai Santa Fe electrical problems

Filed Oct 2, 2026 · Electrical · NJ · fire

On August 14 2026, I drove my 2019 Hyundai Santa Fe approximately one mile from my residence to work at approximately 5:00 AM. The vehicle was operating normally and I experienced no warning lights, unusual noises, odors, smoke, or other indications of a problem. I parked the vehicle in an outdoor parking lot and the vehicle remained parked and turned off for approximately four hours. At approximately 9am, I was notified that my vehicle was smoking. A person who was walking past the vehicle observed the smoke, obtained a fire extinguisher, and extinguished the fire. The fire department subsequently responded, disconnected the vehicle battery, and opened the rear of the vehicle to ventilate it. The fire and resulting heat damage were concentrated on the driver's side rear of the vehicle, directly behind the driver's-side rear tire and in the area of the rear bumper. The plastic at the base of the bumper melted, and melted bumper material was observed dripping onto the ground. The responding fire marshal inspected the vehicle and indicated that the electrical box located in this area may be associated with the origin of the fire. Wiring from this area runs to a non-original/non-Hyundai-installed trailer/tow attachment. The exact cause and origin of the fire have not yet been conclusively determined. The vehicle had otherwise operated normally during my ownership, with little to no significant problems prior to this incident. The vehicle is currently being preserved for inspection by my insurance company and mechanic. I am reporting this incident to the federal safety agency because the vehicle caught fire while parked and unattended after having been driven only approximately one mile, and because the suspected area of origin includes electrical components and wiring associated with the rear of the vehicle. No collision preceded the fire. There were no injuries. I am requesting that the federal safety agency consider this incident as a potential vehicle/electrical safety issue and investig

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 pull over. There were no warning lights and I started home. About a mile from home check engine light came on so contact mechanic. Ended up towing to a dealership and was told the engine must be replaced because the oil had burned off without any warning from the oil light indicator. The turbo also needs replacement. - The combined cost is $14,000. These failures have caused significant financial hardship and stress. I am currently $17,000 underwater on the loan, and the repair costs are overwhelming. The lack of warning before catastrophic engine damage is especially concerning. I believe these issues reflect systemic defects in the vehicle’s design and manufacturing. The repeated failure of critical components—especially the steering system and oil monitoring—make this the worst automotive experience I’ve ever had. I respectfully request that the federal safety agency investigate these failures and determine whether Hyundai should be held accountable. Consumers deserve protection from vehicles with such extensive and costly problems.

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.

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.

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.
