Nice idea, but it's in the part of the seat that you sit on, not the back that you rest against. If the dealer who felt the bumps could have fixed it he would have done so. On our 2005 ES330, if you run your hand over the rear portion of either front seat (the horizontal part) at the rear edge you will feel on each seat two bumps located near the center. If you do not find these please let me know as it may be that my car is not to spec. Thanks, Anthony

Do me a favor. Go to a 2005 ES330. Run your hand over the top of the horizontal part of the seat (the part you sit on) right towards the rear. In our car there are on both the driver and front passenger seats two bumps near the center of each seat. These cause my wife acute discomfort. If they are not present on your 2005 ES330 then our car is not to spec and we can press the dealer to fix it. Many thanks, Anthony

If it were a problem that was amenable to adjustment the dealer would have proposed it. As it is the engineers looked at it, confirmed that the lumps exist and tell us it is "to spec". This problem only is evident on the 2004 and 2005 ES330. It is possible that folks who are less skinny than my wife do not feel the bumps (no insult intended, please!). If you run your hand over the rear of the horizontal part of the seat the bumps are quite evident. If this does not happen in your car please let me know, as this means that our car is not to spec after all. Many thanks.

When we suggested to the dealer that he add padding to make the seats tolerable, he responded that Lexus could not do this as it would open them to liability if the airbags failed in a crash. So should we take that risk ourselves?

If you run your hand over the rear of the seat, not the back of the seat, the horizontal part, you will locate two hard bumps. For those already well-padded there is clearly no problem. For those with slim backsides, there is significant discomfort. Try it and let me know if you find what we have found on every ES330 2005 on our dealer's lot. Thanks.

We are experiencing severe discomfort with a new ES330. Both front seats have several bumps at the back of the seat (the part you sit on, just where the base of the spine hits the seat). The dealer says the seats are to spec and they cannot add cushioning for safety reasons (airbags in sides of seat). We are at a loss as to what to do as dealer (Rallye of Glen Cove) will not take car back and we have a 4 year lease. All other ES330s at the dealer have the same problem. No other Lexus model has lumps in the seats. In fact this car is probably unique in this problem. A friend of ours now tells us that his wife was forced to sit in the back seats of a 2004 Lexus ES330 for the same reason. It would be most helpful to us if we could show the dealer that we are not alone in experiencing discomfort. Please advise. Thanks.
