2009 has not been a good year for <a href="http://www.autoblog.com/make/toyota/">Toyota</a>. After getting its first full-year loss in seven decades, it faced its biggest-ever safety recall over unintended acceleration caused by floor mats and/or throttle control software. Now, as the year draws to a close, a new potential problem has sprung up. This time around, the issue is related to the braking system on the latest <a href="http://www.autoblog.com/model/prius">Prius</a>, which debuted early this year. <br />
<br />
The problem, which has been reported to National Highway Traffic Safety Administration (NHTSA) by several dozen drivers, relates to a loss of deceleration when transitioning from regenerative braking to friction braking. At this time, NHTSA has not opened a full investigation but it is monitoring the situation. <br />
<br />
This is actually quite a complicated issue, and it highlights one of the reasons why it takes automakers so long to bring cars to market. Read on after the jump for some discussion on what might be happening. <br />
