The 2006 Toyota Highlander has 4 recalls, the most serious being a fire risk from aftermarket seat heaters where a damaged copper heating element can short circuit and ignite.
Recall 2 only affects Highlander hybrid models: the inverter can develop a fault that forces the vehicle into a reduced-power limp-home mode, limiting normal drivability. On the brake side, certain brake fluids can cause the master cylinder to leak, leading to a soft or spongy pedal feel and reduced stopping power over time. There is also a labeling recall affecting vehicles sold without the required load capacity information sticker, which means a driver has no clear guidance on how much weight the vehicle can safely carry.
