Toyota Highlander · 2006–2010
On the first- and second-generation Highlander Hybrid (2GR-FXE / 3MZ-FE hybrid), the Intelligent Power Module inside the hybrid inverter assembly carries control-board transistors whose operating temperature can exceed what the solder beneath them tolerates. The solder degrades, the transistor is heat-damaged, and the hybrid system throws multiple warning lamps. In most cases the vehicle drops into fail-safe/limp-home mode with sharply reduced power; in worse cases the power-supply-circuit fuse blows and the entire hybrid system shuts down while driving, stalling the vehicle. This is distinct from the inverter coolant pump failure and from HV traction-battery degradation — here it is the power electronics themselves, not the cooling loop or the pack. Toyota first recalled 2006-2007 cars (11V342000) and then broadened it to all 2006-2010 Highlander Hybrids built Feb 2005 through Jul 2010 under 13V396000 / Toyota campaign D0M.
Common Symptoms
- Multiple warning lights on at once — check engine, slip indicator, brake system, master warning
- Sudden loss of power / limp-home mode
- Hybrid system shuts down and vehicle stalls while driving
- Vehicle will not restart after shutdown
- Reduced acceleration, dashboard warning chime
How to Fix
Free recall remedy: dealers replace the Intelligent Power Module inside the inverter assembly at no cost under NHTSA 13V396000 (Toyota D0M) — check the VIN at nhtsa.gov/recalls, because many of these cars have changed hands several times and never had it done. If the VIN is not covered or the campaign has been performed and the fault returns, the repair is inverter assembly replacement (or specialist IPM board rework), which is the expensive path.
