3 known faults

LS 460

  1. Recall: fuel leak at the supply pipe

    Manufacturer recall

    Worldwide recall (NHTSA campaign 14V-647): residue from anti-corrosion plating can allow fuel to leak at the pressure sensor location on the fuel rail, with a risk of fire. Concerns LS 460 and LS 600h cars built between 2006 and 2010. The free remedy at a dealership is cleaning and resealing.

    Fixed free of charge by a dealer and not counted in the reliability score: ask for proof the work was done (invoice, or a VIN check at a dealer).

  2. Recall: variable-ratio steering (control unit)

    Manufacturer recall

    Recall 10V218: a programming fault in the variable gear ratio steering control unit (VGRS) can wrongly trigger the steering end-stop protection, leaving the steering wheel off-centre by up to 90 degrees. Concerns LS 460 and LS 600h cars built between August 2009 and May 2010. Free remedy: replacement of the control unit.

  3. Air suspension: leaks and compressor

    Severity 2/3 · Costly

    Leaks in the air springs cause the car to sag when parked, and the compressor, which compensates, eventually fails (CarChecker, Au7o). CarChecker estimates the compressor at 2,500-3,000 euros at a dealership and each leg at 1,000-1,800 euros (third-party estimate, not official).

Price and diagnose repairs

Read fault codes

An OBD scanner plugged in under the steering wheel shows stored fault codes, even with warning lights off: useful during the test drive.
