NHTSA found the Lexus HS250h in non-compliance with a recent crash test. Under Federal Law the dealers cannot deliver vehicles in inventory until the problem is remedied.
Probably due to BREAKING: Lexus recalls HS250h over risk of excessive fuel leakage — Autoblog. This post should be moved since it has nothing to do w/Gen III Priuses.
Likely some fuel line is damaged during impact and causing fuel spillage. The fix will be adding shielding to the area where the line is damaged.
From Toyota: Toyota Files Noncompliance Information Report on Certain 2010 Lexus HS 250h Vehicles TORRANCE, Calif., June 25, 2010 – Toyota Motor Sales (TMS), U.S.A., Inc., today filed a Noncompliance Information Report (NCIR) with the National Highway Traffic Safety Administration (NHTSA), informing the agency of the company’s intent to conduct a voluntary safety recall of potentially 17,000 2010 model year Lexus HS 250h vehicles to address a compliance issue with Federal Motor Vehicle Safety Standard (FMVSS) 301. As part of its annual compliance testing program, the NHTSA recently conducted a test of the 2010 model year HS 250h. The test involved striking the vehicle with a deformable barrier from the rear at approximately 50 mph. The vehicle is struck by a moving deformable barrier with a 70 percent overlap. As part of the test, the vehicle was then rotated on its longitudinal axis incrementally to each successive increment of 90 degrees. During the rotation, the vehicle exhibited fuel spillage that exceeded the requirement in the standard. During vehicle development, Lexus tested the HS 250h using the same protocol and found the vehicles to comply fully with the FMVSS 301. Lexus is currently working to identify the reason for the different test results and the cause of this noncompliance. “Even though our own testing of the Lexus HS 250h shows full compliance with federal fuel system integrity standards, we are working intensely to duplicate the noncompliance issue that the NHTSA identified and to determine the reason behind the different test results,” said Steve St. Angelo, Toyota chief quality officer for North America. At the present time, Lexus has not identified a remedy to address this issue, but it is working hard to do so promptly and will notify owners as soon as one is developed. Until then, as required by federal law, dealers will not deliver any new vehicles in their inventory that are covered by this NCIR until remedied. Detailed information about this recall is available through Lexus Customer Satisfaction at 1-800-25 LEXUS or 1-800-255-3987 or at www.lexus.com/recall.
Apparently the problem relates to the filler neck and all that is needed is a bolster which will be available to dealers shortly.
