Consumer Reports has withdrawn its test results on child safety seats, saying further testing is needed.
The consumer watchdog group made the statement Thursday afternoon.
"We withdrew the report immediately upon discovering a substantive issue that may have affected the original test results. The issue came to light based on new information received Tuesday night and Wednesday morning from the National Highway Traffic Safety Administration (NHTSA) concerning the speed at which our side-impact tests were conducted," says a statement from Consumer Reports.
Consumer Reports said Thursday it had received information from the National Highway Traffic Safety Administration showing that the speeds at which its side-impact tests were conducted were higher than the 38.5 mph reported.
In fact, the NHTSA said the crash tests were conducted under conditions that would represent being struck at more than 70 mph -twice as fast as the magazine claimed, said NHTSA administrator Nicole Nason.
"When NHTSA tested the same child seats in conditions representing the 38.5 mph conditions claimed by Consumer Reports, the seats stayed in their bases as they should, instead of failing dramatically," Nason said.
