✓ 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: Frequent topping up (0.5-1 L per 1,000 km in bad cases), hard starting, sometimes code P1604
Fix: Measure consumption over 1,000-2,000 km; only new piston rings (revised parts) cure it, which is often uneconomic; use 0W-20 / 5W-30, not thick oil, with short change intervals
Signs: Engine light, power loss, misfire codes P0300-P0304; on cars with start-stop it can come on suddenly
Fix: Read the coil production numbers and replace coils numbered before 8208; update the engine software
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: Rattling noise from the engine bay, sometimes code P0243
Fix: Fit the revised vacuum line with a retaining clip; replace the boost control valve if it is faulty
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: Scored or lipped discs, vibration or noise when braking; noted at the roadworthiness test.
Fix: Replace discs and pads per axle and clean and grease the caliper slides.
Signs: Rusty brake lines under the car, possibly fluid seepage; surface rust on underbody and body seams; test failure.
Fix: Inspect the lines on a lift and replace corroded sections; treat rust early and protect the underbody.
Signs: Clunk over bumps, car sits lower on one corner, bouncy ride.
Fix: Replace the broken spring or worn dampers in pairs per axle and check the strut top mounts.
Signs: Bulb out, misaligned headlight or faulty rear lamp; a common remark at the roadworthiness test.
Fix: Replace the bulb, check connectors and earth, and adjust the headlight aim.
Signs: No start, or hybrid does not reach READY; electrical warnings after the car stood for a while.
