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. …
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[redacted] For photos and video which I cannot add here on this website through mobile.
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.
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.
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.
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.
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 .
