 I rented a 2017 Hyundai Elantra sedan for a day trip (a 4 hour drive on the interstate one way and 4 hours back, all in the same day). The car 'looks' really nice, but the driver's seat is incredibly uncomfortable. After only an hour of driving, I had pain in my spine from the top of my neck to my lower back, and in my arms, hips, butt and hamstrings. Also, my right big toe kept going numb as my foot was on the gas pedal. I adjusted the seat a million ways - up, down, forwards, backwards - nothing would relieve the pain. I tried adjusting the steering wheel up and down - nothing helped. I don't typically get pain like this from driving, other than my body just getting tired from sitting for too long. Bottom line, I shouldn't get prickling pain after just 1 hour of driving. There is something ergonomically incorrect with these seats. I really think the seats are too low to the floor and that's why no amount of adjustment helps. On a positive note, the headrests were not a problem. They didn't push too forward like they do in some cars. Personally, I never want to rent this car again. It's just too uncomfortable. Maybe it's the right fit for some people, but not for me. The pain that I had from driving this car continued into the following day (after I returned the car to the rental car company). The only thing that started to relieve the pain was going to a yoga class. Last year, I rented a 2016 Hyundai Elantra sedan for a trip and experienced similar pain, but not quite to this extent. I read that Hyundai is making Elantra's seating out of a different material for 2017 (SoyFoam - which seems really cool), but I don't know if that's part of the problem, or if it's just the fact that the seats are too low to the floor. It's unfortunate because if the seats were comfortable, I would consider buying this car... but painful seats are a deal breaker.
