2020 Hyundai Santa-FE Reliability Score & Common Problems

Owners of the 2020 Hyundai Santa Fe frequently report issues with the vehicle's power train, particularly involving transmission and engine performance. Common symptoms include transmission rough shifting, shuddering, and failure to respond when accelerating, often accompanied by warning lights such as the check engine light or transmission warning light. These problems are noted across various mileage ranges, with some occurring as early as 20,000 miles. Safety concerns include unintended acceleration, stalling in traffic, and in one instance, smoke filling the cabin due to an oil leak, which may pose risks of crashes or loss of vehicle control. Buyers considering this model should be aware of potential transmission replacements and engine issues that could affect the vehicle's reliability.

Owners of the 2020 Hyundai Santa Fe frequently report issues with the Forward Collision Avoidance system. Complaints commonly describe the vehicle unexpectedly applying the brakes at highway speeds, even when no obstacles are present, leading to a momentary loss of control. Some owners note that the system activates multiple times during longer trips, while others experience malfunctions in adverse weather conditions, such as snow or rain, which can disable the system. One report includes an injury due to the system engaging at low speed, resulting in physical harm. Owners also mention difficulties with obtaining repairs or responses from Hyundai, with one owner experiencing a prolonged wait for parts. These issues suggest potential safety risks, including the possibility of rear-end collisions if the system acts unpredictably.

Owners report several steering-related issues with the 2020 Hyundai Santa Fe. Complaints frequently mention a sudden loss of power-assisted steering, often accompanying engine failure, which can result in a loss of vehicle control. Symptoms such as a loose steering wheel, unusual noises during low-speed maneuvers, and persistent noise from the steering system are described. These issues are reported at varying mileage, including as early as 19,750 miles. Safety implications are significant, with one owner detailing an incident that led to a traffic citation due to an inability to control the vehicle effectively.

Owners report several issues with the fuel/propulsion system in the 2020 Hyundai Santa Fe. Common symptoms include gasoline fumes entering the cabin, difficulty starting the vehicle in cold conditions, and hesitation during acceleration, with one owner noting these issues at 49,100 miles. Turbo lag is frequently mentioned, with one owner experiencing near-accidents due to delayed engine response when merging or passing, a problem acknowledged by a dealership mechanic. A crash is reported where unintended acceleration led to a collision with a garage, despite brake application. These complaints suggest potential safety implications, particularly concerning acceleration control and engine responsiveness.

Owners of the 2020 Hyundai Santa Fe report issues with the airbag systems, particularly in situations involving crashes and passenger seat occupancy. Two complaints involve crashes where airbags failed to deploy, one in a front-end collision and another in a rear-end impact, resulting in injuries. Multiple reports describe the passenger airbag warning light activating intermittently when the front passenger seat is occupied, with one owner attributing this to an ODS ECU and seat mat failure. These issues occur both during stationary and moving conditions, and the airbag system failures pose significant safety implications, especially in crash scenarios. Buyers should be aware of these potential airbag deployment issues and the associated repair costs.

Owners of the 2020 Hyundai Santa Fe frequently report issues with the service brakes, including unintended activation of the electronic parking brake and brake pedal malfunctions. Symptoms commonly described include the park brake engaging without user input, persistent warning lights, and brake pedal lockup, preventing the vehicle from stopping. These issues are reported to occur both while driving and when the vehicle is stationary, with some incidents leading to crashes. One owner reported a crash resulting in injury, while another described the brakes failing to stop the vehicle, causing rear-end collisions. Complaints arise at various mileage points, with one specific instance occurring around 28,000 miles. These patterns suggest potential safety risks, including loss of control and collision hazards.

Owners of the 2020 Hyundai Santa Fe report issues with unintended acceleration and sudden deceleration. Complaints frequently mention scenarios where the vehicle unexpectedly accelerates, particularly when parking or backing up, leading to crashes in two reported cases. Another owner describes the car dramatically slowing down on the highway while using cruise control, accompanied by warning sounds. These incidents occur without apparent driver error, often after routine maintenance or during normal driving conditions. The safety implications are significant, with reported crashes and loss of control, suggesting potential risks for used car buyers to consider.
