With news this morning of yet another potential Toyota safety problem (steering in 2009 and 2010 Corolla models), it's increasingly hard to keep track of which models are affected by which recalls.
This is your guide to all the recent safety related recalls that affect the Toyota Prius. Thus far, there are only two that affect the issues--brake feel and sticking accelerators--that have been in the news.

BRAKES: 2010 Toyota Prius only
The most recent recall, to update braking-system software, was announced this morning. Letters will go out to 2010 Toyota Prius owners starting next week, and that is the sole model year affected.
Earlier Prius models, built from 2000 to 2009, used a different anti-lock braking system and are not subject to the recall.
The update applies to roughly 133,000 2010 Prius vehicles built from May 2009 through January 2010, as well as 14,500 2010 Lexus HS 250h hybrid sedans.
As reported earlier, Toyota has already incorporated the updated software into the new 2010 Prius models it has built since late in January.
The fix is a dealer-applied patch to the software that controls the anti-lock braking system (ABS). The update improves the system's response time and alters its sensitivity to tire slippage.
Many owners complained that they experienced inconsistencies in brake feel that felt like failing brakes. Toyota says the brakes perform safely at all times, but the update will provide a better feel.
The problem occurs when drivers apply the brakes steadily on slick or bumpy road surfaces, causing the ABS to activate just as the car switches from regenerative braking to conventional hydraulic brakes.
Because the recall is voluntary, owners are not required to their cars updated if they are satisfied with the feel of their brakes. The recall will be free.
ACCELERATION: 2004-2009 Toyota Prius only
The second generation of Prius models, from 2004 through 2009, are affected only by the first of two recalls to address problems with the accelerator.
The first recall is to prevent pedal entrapment, in which an oversize or incorrectly fitted floormat traps the edge of the accelerator pedal, preventing it from returning to its normal position.
The fix announced in October includes removal of incorrect floor mats, using zip-ties to fasten correct mats to their mountings, and sawing a small section off the pedal bottom to shorten it.
Toyota will also fit brake-override software to its cars, ensuring that pressing the brake fully slows the engine even if it is racing.
That recall affects 4.2 million Toyota and Lexus vehicles, including all 2004-2009 Prius models.
But not sticking pedals
The second recall announced in January, however, does not affect any Toyota Prius models. In that situation, acceleration pedal mechanisms provided by one of two suppliers could corrode, causing them to stick.
Toyota plans to modify the pedal mechanisms of affected cars, and it briefly stopped selling affected models until dealers could modify them.
Altogether, Toyota will have recalled about 8 million vehicles on five continents to fix the collection of problems.
