The larger recall of the two stems from the possibility that the nuts securing the pinion shaft for the steering box assembly could become loose from repeated full-lock turning of the steering wheel. The automaker says that over time the driver should notice an increased amount of effort required when turning left.
The fix involves installing four "new and improved" nuts and will take approximately four hours to complete.
The second recall - unrelated to the Prius recall - involves just 50 examples (combined) of the 2011 Venza and Sienna. The only affected models are equipped with all-wheel drive, which resulted in 34 Venzas and 16 Siennas being recalled for the faulty front right-hand driveshaft. Toyota says that the driveshafts were not properly heat-treated and will need to be replaced as there is a possibility they can break - causing the vehicle to coast to a stop.
Toyota will be notifying owners beginning tomorrow via certified mail.
