Nothing has gone wrong with the car.
Nearly all comments on this car have been positive. A couple have said it is boring and to this I must agree. But it is safe and seemingly reliable transportation. I guess if you want exciting, a BMW might be more your style.
My only gripe with the LS400 is in regard to comfort. Most will say that it is a comfortable car, but honestly, I feel more comfortable in my 86 Nissan 720 pickup. One problem is, where do you put your hand or arm when cruising down the highway. Especially your left arm. Putting the seat back a comfortable distance for your legs leaves the armrest for your left arm too far forward. And, my legs are average length for my 5'11", 185 lb frame.
One of the things I enjoy doing on a long road trip is lowering the driver's side window and placing my arm on the window ledge during nice weather. This is uncomfortable with the Lexus, as the center post is too far forward to allow for a comfortable position for my left arm.
I thought the seats were comfortable when I bought the car at the beginning of the winter. I was pleasantly surprised at how quickly the seats seemed to comform to the temperature of my back during the cold weather without the heated seats. Probably due to excellent insulation in the seats I thought. However, this blessing in the winter has turned out to be a negative in warmer weather, as the seats always feel hot on my back, necessitating using the AC. This is true, even on days when it is in only the 60s.
Lastly, the cabin, near the feet and calves, always seems hot, even on days in the lower 60's. Thus you have to fiddle around with the AC, vents, mode and so on to get a comfortable temperature. Again, my truck is more comfortable in all these regards, so it is not like I am really a nitpicker. The car is genuinely uncomfortable.
In summary, I must say regrettably, this is not a car I would want to take on a long road trip. It is just not comfortable to me. Check out these points for yourself if you look at one.
Would you buy another car from this manufacturer? Yes
