2001 Lexus LS
large luxury car / 4-door sedan
Moderate overlap front: original test
Tested vehicle: 2001 Lexus LS 430 4-door
Rating applies to 2001-06 models
The Lexus LS was redesigned for the 2001 model year and renamed the LS 430 because the engine size was increased.
All 2001-06 LS 430 models manufactured after December 2000 include a design change to prevent damage to the wiring harness connecting crash sensors involved in safety belt crash tensioner activation and airbag deployment. (Information about when a specific vehicle was manufactured is on the certification label typically affixed to the car on the driver door or adjacent B-pillar.)
The LS 430 was evaluated in two 40 mph frontal offset crash tests. One car was manufactured before the wiring harness change; the other after the change, following discussions with Lexus. Due to the similarity of results, this evaluation covers both tests.
