✓ The faults of this engine were checked against sources (10/2026). Each item has at least two independent sources or an official recall or parts-maker technical note.
Signs: Fuel smell, fuel leak at the pump on top of the engine; fire risk
Fix: Have a Toyota dealer check by VIN whether recall 23SD-108 was done; the pump is inspected and replaced free if needed
Signs: Rough idle, hesitation, engine light with EGR codes
Fix: Check the EGR valve in live data; clean it, replace if it still sticks
Signs: Coolant level drops, pink or coloured crust around the pump, rising temperature
Fix: Replace the water pump and gasket, refill with Toyota-type coolant and bleed
Signs: After a few days parked the car will not go to READY or unlock properly; random warning lights or 'hybrid system' messages from low voltage.
Fix: Test and charge the 12 V battery, check for open software updates against quiescent drain, and fit the larger replacement battery if it keeps going flat; use a maintenance charger for cars used rarely.
Signs: Several warning lights at once; ABS, pre-crash braking or the electric parking brake may stop working.
Fix: Check the VIN for campaign 21SMD-039; the dealer reprograms the brake control unit free of charge (about one hour).
Signs: Under hard acceleration the car loses drive and shows 'check hybrid system' instead of going into limp mode.

Fix: Check the VIN for the open recall; the dealer activates or reprograms the radar sensor free of charge.
Signs: eCall / SOS warning in the cluster or the emergency call may not connect.
