Let me preface by saying that back in 2000 I was rear-ended by an 18 wheeler into the back of a stopped Greyhound bus, so I have my fair share of back and neck issues....
At the time the 2 vehicles I had narrowed it down to were the Maxima SE and the Passat V6 AWD. The Passat had everything I wanted, especially the AWD but I chose the Maxima strictly because of the seating adjustment possibilities.
IN PARTICULAR- because in the Passat (like our 4Runners) when you raise and lower the back of the seat cushion the entire seat back raises and lowers with it. In the Maxima the seat moved independently from the seatback allowing me to put the lumbar support exactly where my size and shape needed it to be. Are ya listening Toyota? :hello: = )
All of that being said I'm really never unable to find good positions, a variety of them no less, and I've taken many 4++ hour trips.
In a perrrfect world they'd find a way to have the lumbar bubble adjust up and down, kinda like the seatbelt adjustments most vehicles have.
In the meantime, and to address your issue I'd suggest playing around with the overall elevation of the seat in combination with adjusting the steering wheel column every which way (near, far, up and down) as I've learned through the years that even my arm placement can affect my back and neck on long trips but when I find the right combo it makes all the difference.
Hope that helps!
