What is the 2014-2019 Toyota Highlander AC Blower Motor Failure and Resistor Burnout?
The HVAC blower motor in 3rd-generation Highlanders commonly fails or operates intermittently. The blower motor resistor overheats and burns out, causing the fan to work only on the highest speed setting or stop completely. Moisture intrusion through the cabin air filter housing… Repairs typically run $150-$450. Severity: medium.
What is the 2001-2016 Toyota Highlander Catalytic Converter Efficiency Failure — P0420 / P0430 Check Engine Light?
A very common Highlander check-engine complaint is P0420 (Catalyst Efficiency Below Threshold, Bank 1) and its Bank 2 twin P0430. The downstream oxygen sensor readings track the upstream sensor too closely, indicating the catalytic converter is no longer scrubbing exhaust efficie… Repairs typically run $200-$2,500. Severity: medium.
What is the 2008-2019 Toyota Highlander 2GR-FE Valve Cover Gasket & Spark-Plug Tube Seal Oil Leak (Oil-Fouled Coils / Misfire)?
The 3.5L V6 valve cover gaskets and integrated spark-plug tube seals harden and leak with age. Externally the oil weeps and bakes on the block; internally, oil seeps down the spark-plug tubes and pools around the coil-on-plug boots, fouling the plugs and corroding the coils and c… Repairs typically run $250-$900. Severity: medium.
What is the 2014-2019 Toyota Highlander AWD Rear Differential Coupling & Bearing Noise (Whine/Growl That Rises With Speed)?
AWD Highlanders (and platform-mates Sienna, RAV4, Camry and Avalon) develop an abnormal whine, hum, roar or growl from the rear that grows louder with vehicle speed. The source is typically the electromagnetic AWD coupling assembly ahead of the rear differential, which wears and… Repairs typically run $700-$1,800. Severity: medium.
What is the 2014-2021 Toyota Highlander A/C Condenser Leak / Thin-Fin Failure (Rock-Strike Refrigerant Loss)?
The front-mounted A/C condenser on the Highlander is built with thin fins/tubes that owners say cannot survive a stray rock, so it develops small refrigerant leaks and loses cooling — and because the condenser sits low and forward, it gets struck more often than on many vehicles. Repairs typically run $600-$1,100. Severity: medium.
What is the 2014-2020 Toyota Highlander Charging System Malfunction / Alternator Failure (No-Start, Battery Not Charging)?
Owners report a 'Charging System Malfunction' warning and intermittent hard-start / no-start conditions traced to a failing alternator that no longer maintains battery voltage. A healthy unit should read ~13.5–14.8 V at the battery with the engine running; below ~13 V confirms a… Repairs typically run $350-$950. Severity: medium.
What is the 2008-2019 Toyota Highlander Ignition Coil and Intake/PCV Failure Causing Random Misfire (2.7L 1AR-FE / 2GR V6) — P0300?
Highlanders develop random/multiple-cylinder misfires (P0300) plus single-cylinder misfire codes from a cluster of common causes: failing ignition coils, worn spark plugs, a failing PCV valve creating a vacuum leak, and upper intake plenum gasket leaks (especially after a spark-p… Repairs typically run $150-$600. Severity: medium.
What is the 2008-2019 Toyota Highlander Power Liftgate Support Arm and Hinge Failure (Rear Hatch Bows / Won't Close) — Class Action?
The power liftgate on second- and third-generation Highlanders (and the Hybrid) is prone to the power lift arm/strut breaking away from the gate, which lets the driver-side hinge bow and can leave the hatch stuck open or unable to latch closed. A class action filed in 2025 (Morga… Repairs typically run $250-$1,500. Severity: medium.
What is the 2008-2018 Toyota Highlander Front Strut Mount / Suspension Clunk & Knock Over Bumps?
A widely reported Highlander complaint is a clunk, knock or rattle from the front suspension over bumps and during turns. The most common culprits are worn upper strut mounts (including the bearing, which can also cause a creak when steering), tired struts, control-arm bushings,… Repairs typically run $200-$1,000. Severity: medium.
What is the 2014-2020 Toyota Highlander V6 Engine Water Pump Leak and Failure (Weep-Hole Coolant Loss)?
The engine-driven water pump on V6 Highlanders commonly leaks coolant from its weep hole as the internal seal and bearing wear, typically around 90,000-120,000 miles. Early signs are a pink/green crusty residue or puddle at the front of the engine and sometimes a squeal or whine. Repairs typically run $500-$1,500. Severity: medium.
What is the 2014-2019 Toyota Highlander Entune Infotainment Touchscreen Freeze / Blank Display (MFD Lockup)?
Third-generation Highlanders with the Entune head unit commonly suffer the multi-function display freezing or going completely blank — the audio cuts out, the touchscreen and side menu buttons stop responding, and sometimes the screen stays dark on startup. Owners report it happe… Repairs typically run $0-$850. Severity: low.
What is the 2008-2019 Toyota Highlander EVAP Purge Valve / Charcoal Canister Failure — P0441 / P0455 & Fuel-Pump Click-Off?
The evaporative-emissions system commonly sets P0441 (incorrect purge flow) and P0455/P0446 (large leak / vent malfunction). The vapor canister purge valve (VSV) sticks open or closed, or the charcoal canister breaks down internally and sheds pellets that clog the system. A class… Repairs typically run $100-$600. Severity: low.
What is the 2008-2019 Toyota Highlander Rear Cargo / Hatch Water Leak (Taillight & Hatch Seal Intrusion)?
Water pools in the rear cargo area, spare-tire well, and behind the rear interior trim because of leaks at the taillight seals/gaskets and the liftgate/hatch weatherstrip, plus secondary paths through the third (high-mount) brake light, the rear air-deflector/spoiler bracket foam… Repairs typically run $50-$400. Severity: low.
What is the 2008-2016 Toyota Highlander Exhaust Resonance Drone / Boom at 1,500-2,000 RPM — Rigid Exhaust Support Bracket (2GR-FE)?
2GR-FE Highlanders produce a low-frequency drone or boom inside the cabin whenever the engine passes through roughly 1,500-2,000 rpm under load, independent of road speed — most noticeable in light-throttle cruise and on gentle hills where the transmission holds a tall gear. It i… Repairs typically run $150-$900. Severity: low.
What is the 2014-2019 Toyota Highlander Rear Trailing Arm Bushing Squeak / Squawk / Groan Over Bumps (TSB T-SB-0211-17)?

The noise is worst in cold weather and can be reproduced by bouncing the rear of the vehicle by… Repairs typically run $350-$1,100. Severity: low.
