Hello to all. I'm new to the forum and seeking help with a significant problem.
Has anyone experienced very rough ride quality in their LS460L? We just purchased a black 460L for my wife trading in a wonderful LS430 (after 2 LS 400's and an RX300) and find the car to ride very rough, and not at all like the demo cars we drove. The car has the standard suspension as did the demo cars we tested. With only 400 milers on the car, its been in the dealer's shop three times already. The dealer is clueless and Lexus Corp customer service (1-800-xxx-xxxx) is useless in dealing with the dealer. The dealer's service techs lowered tire pressure to 28 lbs, 5 below specification, and the car still rides like it's on rocks. It does not pull but shudders and vibrates at all speeds.
The service manager is guessing flat spotting from the boat trip while the dealer's sales side is saying that's how they ride when equiped with the 18" chrome Telius wheels. Seems odd that the tires are the same Bridgestones as on the demo cars, and the chrome wheels are the same size as the standard wheels, and those all road fine. Sounds to me they're just guessing and hoping we'll go away. Most recently they're talking about putting Michelin Pilot's on the car to soften the ride. I'm pretty familiar with performance riding cars as I drive a high performance sports car on a daily basis and while they're rough, they don't jarr as this one does.
Also does anyone know how to reach a regional manager with real authority at Lexus who could help with this issue? We're on the west coast.
I'd appreciate any help that could be offered with this.
