As expected, Toyota has announced a recall for its 2010 Toyota Prius and 2010 Lexus HS 250h models to update the anti-lock braking system (ABS) software. The new software improves the response time of the anti-lock system and alters its sensitivity to tire slippage.

The update is intended to reduce inconsistencies in brake feel that many owners experienced as brake failure. The recall is voluntary, meaning that owners need not have their cars updated if they are satisfied with the brake feel.

Interaction of ABS, regen & hydraulic brakes

In the 2010 Toyota Prius, 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.

As reported earlier, Toyota has already incorporated the updated software into 2010 Prius models built starting late last month.

About 133,000 2010 Prius vehicles built from May 2009 through January 2010 will be recalled. The recall does not apply to earlier Prius models, built from 2000 to 2009, which used a different anti-lock braking system.

2010 Lexus HS 250h too

The recall also includes all models of the 2010 Lexus HS 250h, the new dedicated hybrid sedan from Toyota's luxury brand, in which drivers may experience the same inconsistent brake feel. The new software will be added to HS 250h models starting later this month.

Toyota plans to mail letters to Prius owners starting next week, and HS 250h owners "within the next few weeks," to let them know they can bring their vehicles to a local dealer. About 14,500 HS 250h models are affected.

The recall extends beyond North America: Toyota announced a recall in Japan for the same issue early yesterday, and globally, about 437,000 Prius models will be eligible for the update.

Toyota acceleration issue: separate

The ABS update recall for the 2010 Toyota Prius and 2010 Lexus HS 250h is separate and unrelated to the two separate recalls of various Toyota and Lexus models to address potentially sticking accelerator pedals.

Those fixes included replacing and securing floor mats, shortening accelerator pedals, and installing brake override software on more than 8 million vehicles globally.

    Bad stuff?

  2. Hi there. I have a 2005 Prius with 105K miles on it. Heard a noise and took it in to be told the transaxle - the transmission for hybrids - was out and would need to be repaired. The total cost $5K. I wrote to Toyota and was told that this is happening with Prius' over 100K miles. They offered $1500 help toward the repair. I had extended warranty to 100K miles - guess what that had expired. So, make sure you get extended warranty and have them check the transaxle just before you hit the 100K miles mark. Also, if like me you are in this boat contact Toyota to complain. They said the more complaints the more likely they are to issue a recall. Finally, I bought this car for the savings in cost with the great mileage - yes the environment too - but basically the savings. The savings with this repair are gone - so if you are thinking of buying it for that primary reason - be aware that at 100K miles you might have a bit of a problem. Good luck and hope this doesn't happen to you.
