My Toyota contacts advise the problem with the Lexus GX460 control issues may be a result of a "re-design" of the KDDS Suspension system. Toyota may need to hire some the brain surgeons from Australia who designed the original Kinetic Suspension system to fix this problem. Neither Neil Yanos nor Kevin Swint were able to offer any solutions.
Brussels, Belgium, March 25, 2008 – Tenneco Inc. (NYSE: TEN) announced that its patented Kinetic suspension technology is featured on the 2008 Toyota LandCruiser 200. Toyota has launched its breakthrough suspension technology, known as the Kinetic Dynamic Suspension System (KDSS), as standard on all five LandCruiser models except on the GXL turbo-diesel where it is offered as an option.
The LandCrusier is the second Toyota sport utility vehicle to feature the KDSS suspension. Tenneco debuted its Kinetic technology on the 2004 Lexus GX470 sport utility vehicle.
Earlier this year, Tenneco announced that it projects it will achieve an average compounded annual OE revenue growth rate of 11% to 13% between 2008 and 2012. This projection includes the Toyota business announced today.
What is KDSS? - Front and rear cylinders, linked hydraulically via a pressure-sensing valve, adjust the GX's stabilizer bars to current road conditions. Off-road, this Kinetic Dynamic Suspension System (KDSS) automatically allows each wheel to move more independently, so the wheel on uneven ground can react while the other wheels are relatively unaffected. This flexibility helps reduce vehicle tilt and improve traction on uneven surfaces. On-road, the front and rear stabilizer bars are automatically fixed in place, helping to minimize body sway while cornering.
... and this just in KDSS is exactly the reason Consumer Reports Recommendation "Don't Buy Lexus GX470" and Toyota is investigating instability problem on all its SUVs?
Good Thing I have '96 Land Cruiser with no KDSS! :)
