Toyota USA Announces Voluntary Recall on 2010 Model-Year Prius and 2010 Lexus HS 250h Vehicles to Update ABS Software
As part of what has become a global recall of the third-generation Prius, Toyota Motor Sales (TMS), USA Inc, will conduct a voluntary safety recall on approximately 133,000 2010 Model Year Prius vehicles and 14,500 Lexus Division 2010 HS 250h vehicles to update software in the vehicle’s anti-lock brake system (ABS). No other Toyota, Lexus, or Scion vehicles are involved in this recall.
Earlier today in Japan, Toyota Motor Corporation announced a recall related to the ABS software program in current-model Prius, the Prius Plug-in Hybrid, Sai and HS250h sold in Japan. (Earlier post.) That recall, for which TMC submitted notifications on Tuesday to Japan’s Ministry of Land, Infrastructure, Transport and Tourism, pertains to approximately 223,000 vehicles. (Earlier post.)
Worldwide, Toyota has sold about 400,000 of the hybrid vehicles subject to the recall announced in Japan. The company said it would take “remedial measures” as soon as possible in the United States, Europe and in other regions.
The ABS, in normal operation, engages and disengages rapidly (many times per second) as the control system senses and reacts to tire slippage. Some 2010 model year Prius and 2010 HS 250h owners have reported experiencing inconsistent brake feel during slow and steady application of brakes on rough or slick road surfaces when the ABS is activated in an effort to maintain tire traction. (Earlier post.)
Toyota has responded to owner concerns with a running production change for 2010 Prius that was introduced last month, improving the ABS system’s response time, as well as the system’s overall sensitivity to tire slippage. The production change for the HS 250h is planned for later this month.
The recall will allow Toyota dealers to perform the software update on 2010 Prius vehicles sold prior to this running production change. Only Prius vehicles produced since May 2009 and all HS 250h vehicles are subject to this recall. First- and second-generation Prius vehicles use a different ABS system and are not involved in this campaign.
The ABS system on the Lexus HS 250h is similar in design to the Prius. The software adjustment planned for HS 250h production and dealer modification is being finalized and will be announced very soon.
Toyota will begin mailing letters to Prius owners included in this recall next week and HS 250h owners within the next few weeks, to let them know when to bring their vehicles into a dealership. Owners will only receive a letter if their vehicle is involved in the recall.
Separately, Toyota will conduct a voluntary safety recall on approximately 7,300 early production - 2010 model year Camry vehicles equipped with the 4 cylinder engine to inspect for a power steering hose that may be in contact with a front brake tube. This contact could lead to a hole in the brake tube and cause a brake fluid leak, increased brake pedal stroke and greater vehicle stopping distance.
