Common Problems: TOYOTA HIGHLANDER
Known issues reported by owners and MOT testers.
- Rear Electric Motor High-Voltage Cable Connector Corrosion ('Cablegate')(Serious)
On Highlander AWD-i models, the high-voltage cable that delivers electrical power from the front hybrid inverter to the rear axle motor exposes its connector terminal housing to wheel spray, road salt, and dirt under the vehicle. Over British winters, galvanic corrosion degrades the braided shielding and terminal seal, resulting in AM radio static, hybrid system fault warnings, and loss of rear electric all-wheel drive.
- Second-Row Seatback Recliner Internal Locking Mechanism Defect(Serious)
On certain Highlander models built between 2021 and 2023, the internal return spring within the second-row seatback recliners was improperly manufactured. The locking teeth may not engage completely when adjusting the seat position, creating a risk that the seatback unlatches and collapses forward or backward under heavy braking or during a collision, leading to an official DVSA safety recall.
