2006 TOYOTA RAV4 with 125600. miles

Steering froze up while leaving my driveway and p/s light came on. Shut engine off and back on, but did not resolve. I recall at least one other time that steering locked up temporarily while at a stop. Took to dealership for diagnostic as manual recommends. Diagnostic shows dtcs U0105 and U0121. Found tab st005-06 related to this issue and "updated power steering ecu available". Diagnostic $150, parts and labor $1600+ cleary this is a safety issue requiring a recall. Please investigate there are many more similar complaints.

2006 TOYOTA RAV4 with 70162.0 miles

Heard abnormal mechanical rattle from the front end going over rough streets in san francisco. Took vehicle in suspecting suspension issue to capitol Toyota of san jose. Diagnosis was steering rack has a known part issue, internal to its design, nothing the dealer could do, as factory did not allow them to open the part up, only replace it. Dealer was unable to tell me if the car was safe or not to drive. Said only thing they could so was replace the entire steering rack at $2000 +, which is outrageous. They said if i had extended warranty they would swap it out, and this is done all the time for this model and year! This car is serviced regularly and not driven off-road. This is a design defect that could pose a threat if the steering were to lock up/fail while driving, yet Toyota refuses to address the issue and says its wear and tear. At 70k miles? This part should last 200k. There are many reports online of issues with the steering system.
