2020 Toyota Highlander Reliability Score & Common Problems

Owners of the 2020 Toyota Highlander frequently report issues with the vehicle's front bumper, with numerous complaints describing the bumper detaching or falling off while driving, often at highway speeds. This issue is linked to a recall, although many owners express frustration with delays in repair parts availability and conditions imposed by dealers before completing recall repairs. Affected vehicles often have mileage ranging from approximately 7,000 to 89,000 miles. Additionally, some owners report problems with the sunroof glass shattering unexpectedly, posing a potential safety risk. These structural issues could be relevant for potential buyers assessing long-term reliability and safety.

Owners of the 2020 Toyota Highlander frequently report issues with the fuel system, particularly involving the inability to fill the fuel tank to its advertised capacity of 17.1 gallons. Many describe being able to add only 12 to 13 gallons even when the fuel gauge indicates near empty, leading to a reduced driving range of approximately 420 to 500 miles instead of the expected 600 miles. Complaints also often mention inaccurate fuel gauge readings, where the gauge fails to register a full tank after refueling and inaccurately indicates fuel levels when nearing empty. These issues collectively pose potential safety risks, as they may lead to unexpected fuel depletion while driving. Buyers considering this model should be aware of these recurring fuel system concerns.

The rear hatch is also problematic, with multiple owners describing it as failing to open or close properly, sometimes requiring manual intervention. Additionally, some owners report battery-related issues, where the vehicle fails to start without a jumpstart, even after a few hours of being parked. These issues appear at various mileages, with some occurring as early as 11,000 miles. Safety implications are noted in complaints about the vehicle stalling or losing power while driving, which could pose a risk in traffic situations.
