2015 Toyota Highlander Hybrid — Should You Buy One?

Typical asking price: $17,000–$25,000. This is one of the more reliable vehicles in its class — here's what to watch for anyway.

Kestrel Take

A three-row SUV that returns 28 mpg using the most proven hybrid system on earth. The 2GR V6 paired with Toyota's eCVT has no torque converter, no clutch packs, and no CVT belt. As a family vehicle you intend to keep for a decade, it is very hard to argue against.

What we checked

Partly reconciled against public records, 2026-09-11

NHTSA holds 182 owner complaints for the 2015 Toyota Highlander Hybrid, and no recall campaigns.

A big number here usually means a lot of these were sold, not that it is a bad vehicle — popular models collect more complaints for the same rate of trouble. So the total on its own says little. What is worth reading is the shape of it. The largest single group is electrics and electronics at 27%. That is notable without being overwhelming — worth checking, not worth panicking about.

Not written up yet: steering (23 complaints). That group is in the public record and is not covered by the issues below. Treat it as something to ask about, not as absent.

Counts come from the NHTSA complaint and recall database — free, public, and worth checking yourself.

Known Issues for the 2015 Toyota Highlander Hybrid

Ranked by wallet impact. These are documented, recurring problems — not freak accidents.

Hybrid battery agingMedium

The nickel-metal-hydride pack degrades slowly and reconditioned replacements are widely available at reasonable cost. Symptoms are reduced economy and a state of charge that swings quickly.

Repair cost (estimate): $2,000-$4,500

Source: NHTSA complaints filed under electrics and electronics (49), the engine (12).

Water pump seepage (2GR)Medium

Weeping around 100k-140k miles. Routine on this engine.

Repair cost (estimate): $500-$1,000

Source: NHTSA complaints filed under the engine (12).

Inverter coolant pump failureMedium

A failed inverter pump triggers a hybrid system warning and can disable the drivetrain.

Repair cost (estimate): $400-$900

Source: NHTSA complaints filed under the engine (12).

Brake actuator assembly failureMedium

The regenerative braking actuator is an expensive failure that lights multiple warnings at once.

Repair cost (estimate): $1,800-$3,000

Source: NHTSA complaints filed under the brakes (15).
