2019 Hyundai Santa FeRecalls, problems, MPG & safety

“On 03/26/2026, my 2019 Hyundai Santa Fe received Hyundai Service Campaign 9C2 (TSB 26-01-013H-1), which included an Engine Control Module (ECM) software update for Theta II emissions improvement. The vehicle did not have the following drivability problem before this software update. Immediately after the 9C2 update, the vehicle began jerking/bucking slightly at low speeds, most noticeably around 10-20 mph when coasting with no accelerator input or when applying very light throttle. Acceleration response also feels slower than before the update, with noticeable hesitation when the accelerator is pressed. The problem is most noticeable during the beginning of a drive when the vehicle is cold. After driving for some time and the vehicle warms up, the symptoms improve, although the change in drivability remains noticeable compared with operation before the update. There have been no warning lights or warning messages associated with the problem. The issue began immediately following the ECM software update. The vehicle has not yet been returned to the dealer for diagnosis or confirmation and is available for inspection. I am concerned about the safety implications…”

“Driving at highway speed, vehicle stuttered/lurched. The check AWD, engine light, tire pressure warning lights came on. Check by mechanic resulted in error code P0741 (Torque Converter Clutch Circuit Performance or Stuck Off). Search of error code P0741 indicates that there is a Technical Service Bulletin TSB-23-AT-005H regarding this KNOWN problem. A stutter or lurch of the vehicle can cause the driver to over react, stop or swerve suddenly in traffic potentially causing an accident not to mention possible being struck on the side of the road while waiting for a tow/service truck. Vehicle/components have not been checked by manufacturer--only diagnostic code by Mechanic. Warning lights after incident included the AWD system, Check Engine Light, and Tire Pressure sensor light. Vehicle is being towed to a Hyundai Dealership as Mechanic advised it is not safe to drive.”

“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…”
