I took the family up to Tahoe last Christmas and it was white out conditions. The pilot was flawless. We drove up to highway 89 towards Homewood until we realized the road is closed prior to getting to Homewood. We did notice a Pilot without 4wd on the way back had problems on some of the steeper grades. With our 4wd pilot we had no problems. We also drove from South lake tahoe to Sierra at Tahoe ski resort. There were highway patrol checkpoints to ensure vehicles without 4wd had chains, however with our pilot we just drove right through the checkpoint. Just make sure that you take it nice and slow even with 4wd and you'll be alright.
