2006 Lexus Rx400h recalls & complaints
Source: NHTSA, updated daily. Last checked 2026-10-19. Recalls apply to specific VINs — run your VIN to confirm.
5 safety recalls, most serious first
1. Engine
What's wrong, in plain English: Engine problems range from stalling to fire. THE AMOUNT OF ADHESIVE AGENT APPLIED BETWEEN THE OUTER RING AND THE TORSIONAL RUBBER DAMPER (INNER RING) IN THE CRANKSHAFT PULLEY MAY BE INADEQUATE. IF THE ADHESIVE IS INSUFFICIENT, THERE IS A POSSIBILITY THAT THE OUTER RING MAY BECOME MISALIGNED AND IT MAY NOT PROPERLY ROTATE WITH THE INNER RING, CAUSING NOISE AND/OR ILLUMINATION OF THE BATTERY DISCHARGE INDICATOR LIGHT.
What could happen: IN SOME CASES, THE BELT FOR THE POWER STEERING PUMP MAY BECOME DETACHED FROM THE PULLEY WHICH COULD RESULT IN A LOSS OF POWER STEERING AND A SUDDEN INCREASE IN STEERING EFFORT, INCREASING THE RISK OF A CRASH.
The fix: TOYOTA WILL NOTIFY OWNERS, AND DEALERS WILL CHECK THE CRANKSHAFT PULLEY TO IDENTIFY WHETHER IT WAS PRODUCED BY THE U.S. SUPPLIER. IF SO, THE DEALER WILL REPLACE THE PULLEY WITH A NEW ONE AT NO CHARGE. THE SAFETY RECALL IS EXPECTED TO BEGIN DURING EARLY JANUARY 2012. OWNERS MAY CONTACT TOYOTA AT 1-800-331-4331.
What to do
- Check whether your car is affected: enter your 17-digit VIN at nhtsa.gov/recalls. A recall covers specific VINs, not every 2006 RX400H.
- Book a repair at any authorized Lexus dealer. Quote NHTSA campaign 11V539000.
- The repair is free. By US law, safety recall repairs cost the owner nothing, no matter the car's age or mileage.
- Manufacturer hotline: 1-800-331-4331.
- Buying this car used? Ask the seller for proof the recall was completed, or run the VIN yourself before paying.

4. Hybrid / EV system
What's wrong, in plain English: High-voltage battery or drive system. The Intelligent Power Module (IPM) inside the inverter module may contain transistors that have higher operating temperatures than the solder can support and the transistors may be heat damaged by the solder. If this occurs, various warning lamps, including the malfunction indicator lamp, slip indicator light, brake system warning light, and master warning light, will be illuminated on the instrument panel.
What could happen: The vehicle may enter a fail-safe/limp-home mode that limits the drivability of the vehicle. It is possible that the hybrid system will shut down while the vehicle is being driven, causing the vehicle to stall unexpectedly, increasing the risk of a crash.
The fix: Toyota will notify owners, and dealers will replace the IPM free of charge. Owners may contact Toyota at 1-800-331-4331. Vehicles that had their IPM replaced under recall 11V-342 are not affected by this campaign.
