Lexus Stops Deliveries and May Recall HS 250h after NHTSA Tests Find that Rear-End Crash Leads to Excessive Fuel Spill

[Updated] Toyota has just issued an official release stating its intention to stop deliveries and conduct a voluntary safety recall of around 17,000 examples of the 2010MY Lexus HS 250h hybrids to address the NHTSA's concerns over the excessive amounts of gasoline that were leaked during a standard rear-end crash test performed by the safety agency.

The Japanese automaker said that during the Lexus HS 250h's development phase it had tested the hybrid car using the same protocol and found the vehicles to comply fully with the Federal Motor Vehicle Safety Standard (FMVSS) 301.

"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.

Toyota Press Statement

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.

Statement from Mark Templin, Lexus Group Vice President and General Manager

“We are concerned with the results of the annual National Highway Traffic Safety Administration (NHTSA) compliance test on the 2010 Lexus HS 250h hybrid. Our engineers conducted similar testing during the development of the new HS 250h and the vehicle performed safely.

“We take the NHTSA’s test results very seriously and appreciate the NHTSA bringing its concerns to our attention. We want to assure our customers that their safety and satisfaction are our top priorities. While we are investigating and vigorously working to understand the different test results, we have stopped delivery of the involved vehicles. As soon as the issue is better understood and/or a remedy is developed, we will contact every owner.

“Customers who have any questions or concerns should contact their local Lexus dealer or Lexus Customer Satisfaction at 1-800-25LEXUS or 1-800-255-3987.”
