Only three 2004 model year sport utility vehicles earned perfect scores in the latest series of US government frontal and side-impact crash tests, federal safety regulators said on Wednesday.

According to Reuters, the National Highway Traffic Safety Administration said the Infiniti FX, Saturn Vue and Toyota Highlander all got five out of a possible five stars for protection of their occupants against serious injury in the closely watched tests.

The redesigned Dodge Durango also won a perfect rating in the frontal crash test, in which vehicles are pulled into a fixed barrier at 35 miles per hour. But side-impact tests were not conducted on the Durango, NHTSA said, according to the report.

Reuters said vehicles scoring poorly in the frontal tests were all from General Motors and included the Chevrolet Trailblazer, Buick Rainier, GMC Envoy and GMC Envoy XUV, Isuzu Ascender, Oldsmobile Bravada, which are built off the same platform or chassis. All got a lowly three-star rating for protection of front seat positions in a crash.

The Cadillac SRX and Toyota RAV both got four-star ratings in the frontal crash tests, NHTSA reportedly said.
