Gear oil weeping from the transfer case seals on AWD models, potentially causing a burning smell.
Inspect · Look under the vehicle just behind the front subframe with a torch. Inspect the transfer case housing for dark, thick gear oil residue or fresh drips where it mates to the transmission.
Knocking noise from the rear over bumps or visible fluid weeping from the damper body.
Inspect · Shine a torch into the rear wheel arches to check the shock absorber bodies for oil misting or fresh fluid leaks. Push down firmly on the rear corners to test damping and listen for knocks.
Melting / sticky dashboard in hot climates (warranty extension).
Inspect · Press the dash top for tackiness and glare.
Clicking noises from behind the dashboard or failure to regulate cabin temperature evenly across dual zones.
Inspect · Turn the ignition on, set the climate control to dual zone, and adjust the passenger and driver temperatures to opposite extremes. Listen for clicking behind the glovebox and check the vents for correct temperature output.
Brake actuator faults (hybrid RX450h).
Inspect · Scan for brake-actuator codes on hybrids.
Water pump seepage.
Inspect · Look for coolant residue at the pump.
Oil-supply line / VVT hose seepage on some cars.
Inspect · Check for oil residue around the VVT hose.
Power tailgate fails to open or close fully, beeps continuously, or drops down after opening.
Inspect · Operate the power tailgate using both the key fob and the dashboard button. Ensure it opens fully without assistance, holds its position at the top, and closes smoothly without binding or excessive motor whining.
