They used to be made by Araco (maybe until '05 ish). The 4Runners have also been having problems with rattling moonroofs, as well as play/movement in the driver's seat, and vibration at certain rpms since '03 w/ no fixes yet.
Are you using the stock tires in the snow? Which did you get, the Dunlop GrandTreks or Bridgestone HT's?
I got 15mpg on 87 octane gas (mostly city), est. of 17+mpg on this tank so far (mostly hwy, 55-60mph, 91 octane chevron). Nav estimates 19.5mpg for last weekend's day trip, but it seems to be optimistic. The vehicle has lots more power using 91 octane over 87 on the hills (you don't have to press the accelerator as hard, plus I have a very light foot), so you use less gas. Altitude here is from 2500-5000 ft, humidity of 5-20%.
I just purchased an used 06 and really enjoy the ride. However, I do have a slight vibration/rattle noise coming from somewhere inside the cabin. It only happens at low speeds going over imperfections in the road (cracked pavement, small bumps). Seems to be coming from the gear selector area but not sure. Also notice driver's seat shifting. Thinking of having the dealership trouble shoot the vibration. Does anyone know if they will replace the driver's side seat or just shimmy it? First time lexus owner so not sure what to expect.
Thanks!
