Toyota Sequoia Common Problems

ELECTRICAL SYSTEM

Owners report frequent issues with the electrical system of the 2018 Toyota Sequoia, particularly involving the vehicle's safety sensors and warning systems. Common symptoms include malfunctioning blind spot monitors, rear cross traffic alerts, adaptive cruise control, and pre-collision warning systems. These issues often manifest at low mileages, with several complaints noting problems as early as 30 to 500 miles. There are safety implications, as some owners describe the vehicle's auto-braking feature activating unexpectedly, which could potentially lead to hazardous situations if it occurs in traffic. Buyers should be aware that despite software updates and repairs, these problems frequently recur, and resolution may be ongoing.

UNKNOWN OR OTHER

Owners of the 2018 Toyota Sequoia report several issues under the unknown or other category. One complaint involves the sunroof unexpectedly exploding from the inside while driving at highway speeds, which could pose a safety risk. Another issue frequently mentioned is the audio multimedia system, including hands-free and GPS functions, repeatedly rebooting without reason, potentially distracting the driver. Additionally, the pre-collision system (PCS) is reported to malfunction, with the PCS off light illuminating incorrectly and the system failing to apply brakes in near-collision scenarios. The mileage at which these issues occur is not specified, but the safety implications, particularly with the PCS and sunroof, may be notable for potential buyers.

POWER TRAIN

Owners of the 2020 Toyota Sequoia report issues related to the power train, with one complaint describing a failure to accelerate at highway speeds and a subsequent loss of motive power and stalling, occurring around 41,000 miles. Another complaint involves an incident where the vehicle was left in gear and rolled backwards, resulting in an injury when the owner attempted to re-enter the moving vehicle. These reports highlight potential safety implications, including the risk of vehicle stalling and unintended vehicle movement. Used car buyers should be aware of these symptoms, especially around the reported mileage, as they may indicate underlying issues with the power train system.

UNKNOWN OR OTHER

Owners of the 2019 Toyota Sequoia report issues with the fuel filler door and moonroof. Complaints frequently mention the fuel filler door hinge and pin being bent, leading to difficulties in opening, closing, and fueling the vehicle, with uneven spacing noted around the door. Another issue reported involves the moonroof, with one owner describing an incident where the moonroof glass exploded outward while driving at highway speeds, though no external impact was involved. These issues appear to arise without specific mileage patterns, and there are no reports of crashes or injuries associated with these complaints. Used car buyers should be aware of these potential issues, particularly concerning the fuel filler door's functionality and the integrity of the moonroof.

FUEL/PROPULSION SYSTEM

Owners of the 2018 Toyota Sequoia report issues with the fuel pump, including symptoms such as extended crank times and a loss of power. These symptoms are similar to those described in a specific recall, though some owners note their vehicles are not included despite experiencing identical issues. Complaints also highlight service-related problems, where a recall fix was not performed during scheduled maintenance due to unclear communication and service documentation errors. These issues typically arise without a specific mileage range mentioned, but the safety implications include potential power loss while driving. This information is useful for potential buyers to consider when assessing the maintenance history and recall status of a used 2018 Toyota Sequoia.
