2012 Toyota sienna developed a "clunk" in steering system while turning from a stopped position. The clunk can be felt through both the steering wheel and floor. This is caused by a well-known safety problem Toyota has had with several other models including rav4, highlander, and camry (some of which had recalls).

What stands out
No new NHTSA steering complaint has been filed on this vehicle in over 6 years — the issue may be aging out of the active population.
The failure pattern owners describe
Buyer takeaway: The 2012 Sienna has a well-documented intermediate steering shaft defect causing knocking and clunking starting around 50K miles; repairs run $650–$750 with no recall coverage. More serious are reports of sudden power steering loss and steering wheel jerking at highway speeds, creating genuine safety hazards.
The 2012 Sienna steering system shows a clear pattern of intermediate shaft failure. Starting around 50K–80K miles, owners hear knocking, clunking, or thumping sounds when turning—especially at low speeds under 35 mph. The noise originates from the lower steering column and gets louder over time. Dealers consistently diagnose and replace the intermediate steering shaft, billing owners $650–$750 each; Toyota has issued recalls for this defect on RAV4, Highlander, and Camry but not the Sienna. Owners report Toyota refusing warranty coverage.
More serious are intermittent power steering failures. One owner's power steering quit suddenly on the highway after the battery light came on; replacing the battery, alternator, and serpentine belt fixed it temporarily, but the problem returned. Another reported the entire electrical system shutting down during a routine lane change, with a mechanic advising immediate towing due to safety risk.
One owner reported steering jerking left and right independently at 35 mph, requiring intermediate shaft replacement. A steering angle sensor code (C1433) was flagged in one complaint. Throughout, owners note they feel unsafe and question why Toyota has not recalled this known defect across its lineup.
