SERVICE BRAKES
Owners of the 2021 Hyundai Tucson frequently report issues with the service brakes, particularly involving an electrical short in the ABS module that poses a risk of engine compartment fires, as highlighted in multiple recall-related complaints. Several owners describe a lack of availability of parts needed for recall repairs, resulting in extended wait times and concerns over safety due to the potential fire hazard. Additionally, some owners mention problems with the brake pedal becoming soft and requiring excessive pressure, often linked to a suspected vacuum assist issue, with one owner noting resolution after replacing a check valve themselves. These issues are reported across various mileage ranges, with some problems appearing as early as within the first year of ownership. Safety implications include increased stopping distances and potential loss of brake power, although no crashes are explicitly reported. This information is pertinent for used car buyers to consider, given the potential for unresolved recall repairs and brake system concerns.

ELECTRICAL SYSTEM
Owners of the 2021 Hyundai Tucson frequently report issues with the electrical system, particularly concerning the air conditioning and rear view camera. Multiple complaints describe the air conditioning system failing at under 55,000 miles, with extensive parts replacements not resolving the issue. Additionally, the rear view camera is noted to be ineffective at night. Some owners experience repeated knock sensor failures leading to limp mode, significantly impacting vehicle performance and posing a safety risk due to sudden deceleration. There are also reports of poor vehicle performance and reduced fuel efficiency following a dealership software update, with no resolution from the manufacturer. Safety concerns are highlighted in complaints about potential fire risks related to the ABS module, with suggestions to park vehicles outside. These issues suggest potential reliability concerns for prospective buyers, especially those considering vehicles with higher mileage or those produced before November 2020.
