Car sick in the back seat?

[KEI7]

For those of you who drive with your kids in the back seat, or those who used to;

So I have kids, 4 yr old daughter and 2yr old son, and whenever my daughter rides the car in the back seat for more than an hour of drive, she always says she got car sick.

She sits in her child seat (which is the only place she will be until old enough) in the back.

My previous car was a E61 (530i wagon with m sport suspension), and it was never the case with the E61.
Though, I am speculating it may have been just because she was not old enough at that time (age 2), as my son who is currently 2 y/o never complains in the E53.

I only have the X5 and cannot compare, but am also suspecting that maybe it has to do with the way E53 (or to an extent tall SUVs in general) moves, due to higher center of gravity.
When I first drove the E53 the “shake” (kind of like a sideways wiggle shake on bouncy and uneven roads ) was pretty noticeable compared to the E61. I can’t really put it down in words but it is obviously not a movement from anything wrong with the car, but from the characteristic thereof.

My question is, any of your usual passengers like your family member get car sick uniquely when riding your E53?
Like he/she/they are ok with any other car but gets uncomfortable or sick in E53?


By the way my E53 is ’06 with 44k miles with tires only 1 year old and suspension components in ok condition, checked by my mechanic and myself, so pretty safe to remove possibility of any issues wrong with the car. 19" Style 132s in summer and 17" studless in the winter, but my daughter feels sick regardless
