What the known faults on this Toyota Sienna typically cost to put right at a UK independent garage · use the figures to price risk before you bid, and to justify a reduction when something shows up on inspection.
The single priciest documented job on the 2011–2020 Toyota Sienna is automatic gearbox service or rebuild at £350–£3,000. Few cars need every repair listed here · treat £1,570–£8,650 as the full exposure if one arrived with all of them.
Hesitation, surging, or harsh gear engagements at low speeds on 2017 onwards models with the 8-speed automatic gearbox.
Inspect · Conduct a low-speed test drive at 10-20 mph. Repeatedly apply and release the throttle to see if the gearbox clunks or hesitates when deciding which gear to select.
Vague steering feel, clunking over speed bumps, and accelerated wear on the inner edges of the front tyres.
Inspect · Apply the handbrake firmly, engage drive, and lightly blip the throttle while an observer watches the front wheels for excessive fore-and-aft movement indicating torn lower control arm bushes.
Dashboard glare / softening in hot climates.
Inspect · Check the dash top for tackiness.
Rubber oil-supply hose (VVT) leak on early cars (recall).
Inspect · Confirm the oil-hose recall was completed.
Brake actuator / ABS sensor faults triggering warning lights.
Inspect · Scan for ABS/VSC codes on the test drive.
Coolant leak and whining noise from the auxiliary belt area due to water pump bearing failure.
Inspect · Open the bonnet and shine a torch down the right side of the engine block. Look for a build-up of dried, pink coolant crust around the water pump pulley.
Knocking or rattling sensation felt directly through the steering wheel over rough surfaces due to intermediate shaft wear.
Inspect · With the engine running and the vehicle stationary, rock the steering wheel rapidly left and right. Listen closely for a distinct metallic clunk originating from the driver's footwell.
Power sliding door cable / motor failure.
Inspect · Cycle both power doors several times and listen for grinding.
