I'm 53 and have put over 400k miles on my 87 BMW 535, and I can still drive that car from tankful to tankful without having to even get out and stretch.

 

Yep ....never had this problem when I was younger . I have to stop and stretch my legs after 3 hrs or so. SUV and trucks are the worst for me,

 

I'm feeling this within about 10-15 mins
Its definitely specific to the truck.

My last car had TERRIBLE seats - 2000 Honda Insight, but never had this issue. The seating position was typically low though as you'd expect in such a small car so my leg was stretched out vs straight down like the D2.

 

At the risk of being a dweeb, I'll chime in. I'm 6-5 and 290, solid and strong, not soft and weak. I'm 54.
I moved the drivers side cupholder to the passenger side to give my leg more angle. Its in the mods. I experience similar leg falling asleep issues In my Silverado if I drive more than 3 hours without stretching.
Used to travel the world. Long flights sucked.

 

I have this issue with a lot of cars, sciatica pain. Interestingly enough the D2 doesn't do it for me. Neither do most Land Rovers, I've noted that if my left thigh (usually my left leg) is touching the bottom of the seat, I'll start to hurt. I am only 5'8" 160lb

 

I'll look at this - I get the point but havent thought about this. Thanks for the tip.

I have zero pain - I have a buddy with the same issue - he had to sell the car after realizing it was the car causing the problem. Hour commute in a Chevy Cobalt... lol
With no pain, I know its a position issue, just hoping I can figure it out.

I'm actually very interested in taking my seat cushion to an upholstery shop and have them replace the foam - not only with new foam but maybe something a little more cushy and maybe 1/2 - 1" shorter.

 

Being able to slide the seat back more helped me. There wasn't much info on how to do it but there was enough on here.

 

Most likely one of two things are happening.

1) Your wallet is pressing on the sciatic nerve running through the piriformis muscle and down the leg causing the symptoms.

Or

2) Your posterior chain (calves and hamstrings ) are tight due to either sitting too upright in the rover or just tight overall creating pressure on the nerves.

Certain diagnostic tests could narrow it down fairly easily.

I work on these two things with my patients all the time.

 

My wife says I suffer from no-***-at-all syndrome (lol) coupled with your reasoning makes sense due to keeping my wallet in my back pocket when I drive.

 

i completely got rid of the incipient sciatic issues i was starting to develop several years ago by shifting my wallet from my back pocket to a front pocket. altering that one habit was literally life-changing.
