When you make more than 10 million cars per year, if something goes wrong on a significant batch of them, the recall size is going to be pretty big. Toyota has been a case study in this concept over the past year or so, today adding another 740,000 vehicles in the U.S. and over 1.5 million worldwide to the recall rolls.

Owners of 2006 Lexus GS300, RX330, IS250 and IS350, vehicles as well as owners of 2004-2006 Toyota Highlander non-hybrids and 2005-2006 Avalons should prepare to bring their cars in for service as part of the voluntary recall issued today.

The problem this time? Again, it involves the brakes, but this time it's the fluid. During maintenance of the brakes, if the proper "Toyota genuine" fluid isn't used, a seal in the master cylinder may not be lubricated properly, dry out, and cause the brakes to leak fluid, lighting a warning signal on the dash and potentially decreasing brake performance and pedal feel. The fix is to install a redesigned brake master cylinder cup.

Notifications to affected owners will begin early in November with service (at no charge) to take place at Toyota and Lexus dealers.
