2018 Hyundai Santa-FE Reliability Score & Common Problems

Owners report frequent issues with the 2018 Hyundai Santa Fe's electrical system, particularly involving oil leaks from the oil pressure sensor that lead to electrical component damage, including potential fire hazards. Complaints frequently mention symptoms such as oil leaks causing smoke, engine lock-ups, and malfunctions in electrical components like the dash cluster, rearview camera, and ignition system. These issues often appear around 18,000 to 60,000 miles. Safety implications are significant, with multiple reports of fires, engine failures during driving, and loss of vehicle power, which pose risks of crashes or injuries. Prospective buyers should be aware of these patterns and the potential for costly repairs or safety risks.

Owners of the 2018 Hyundai Santa Fe frequently report issues with the powertrain, particularly involving engine failure and excessive oil consumption. Common symptoms include engine knocking, metal shavings in the oil, and sudden stalling or loss of power, often accompanied by a check engine light. These problems typically arise around 80,000 to 100,000 miles, though some cases occur as early as 6,000 miles. Safety implications are significant, with one report of a crash and two injuries linked to these issues. Buyers should be aware of potential high repair costs and warranty challenges, especially for second-hand owners, as multiple complaints highlight dissatisfaction with warranty coverage and dealer responses.

Owners of the 2018 Hyundai Santa Fe frequently report issues related to excessive oil consumption, with some noting the need to add oil every 700 to 2,000 miles. Symptoms often include the illumination of the oil warning light, abnormal engine noises, and visible smoke from the exhaust. Several reports also mention engine stalling or loss of power while driving, sometimes accompanied by a scraping or clicking sound. These issues commonly arise around 60,000 to 149,000 miles. Safety implications include potential engine failure leading to loss of motive power, but no crashes or fires are reported. These patterns suggest prospective buyers should be cautious of engine performance and oil consumption when considering this model.

Owners of the 2018 Hyundai Santa Fe frequently report issues with vehicle speed control, particularly involving unintended acceleration and hesitation during acceleration. Common symptoms include the vehicle accelerating without pressing the gas pedal, failure to accelerate from a stop, and engine RPMs spiking unexpectedly. These issues often occur at low to moderate speeds and are sometimes accompanied by a lack of warning lights or diagnostic codes. One complaint involved a crash with an injury, highlighting potential safety risks. Patterns suggest these problems can occur even with relatively low mileage, as some reports involve vehicles with less than 1,000 miles. Buyers should be aware of these potential issues when considering this model.

Owners report several steering-related issues with the 2018 Hyundai Santa Fe. Common symptoms include a loose or unstable steering column, often accompanied by popping noises and a feeling of the steering wheel potentially detaching. Complaints frequently mention steering "stiction," where the wheel sticks and requires extra force to move, leading to overcorrection, especially at speeds above 40 mph. Affected vehicles often exhibit these problems after approximately 10,000 miles, with some cases occurring as early as six months after purchase. Safety implications are significant, as multiple owners describe situations where the steering becomes difficult to control, and in some cases, the steering assembly was found to be cracked or detached. Buyers should be aware of these potential issues and verify if any recalls have been addressed.

Owners of the 2018 Hyundai Santa Fe frequently report issues with airbag deployment failures, particularly during crashes, with three incidents involving collisions where airbags did not deploy, resulting in two injuries. Common symptoms include airbag warning lights illuminating, passenger airbag sensors malfunctioning, and instances where airbags are suspected not to deploy during a collision. Complaints often mention these issues occurring around 42,000 to 75,000 miles. Some owners describe problems with obtaining replacement parts for faulty sensors, leading to prolonged periods where the vehicle is considered unsafe to drive with passengers. These patterns suggest potential safety implications, especially in scenarios where airbags fail to activate during accidents.

Owners report several issues with the exterior lighting of the 2018 Hyundai Santa Fe, notably involving headlight performance and brake light functionality. A common problem involves dark shadows or spots cast by the headlights, which some owners say obscure visibility, especially on unlit roads. Several complaints also mention headlights going out unexpectedly, either while driving or when using turn signals, with one incident resulting in a crash and injuries. Mileage at which these issues occur varies, with one report noting a failure at 58,000 miles. Safety implications are significant, as the headlight problems can hinder visibility and have led to at least one accident.
