Quoted from pcprogrammer:
Back on the hunt for a new vehicle again. I like our 2010 Sienna so I figured another van would be the way to go. Opinions on these 2 vans? I'm going to get the EX-L with the infotainment stuff on the Odyssey or the XLE Sienna but I think the package with the entertainment stuff costs a couple grand more. I test drove both today and like both a lot.
My only warning would be to look into a VCMuzzler if you get the Honda. Since 2008 they have been prone to having excessive oil consumption problems and in some cases killing engines that ran dry with no check engine light coming on for the oil when it got low. Odyssey with the problem can use a quart or more every 1000 miles, which Honda tried to say is "normal" - and they got sued for it and settled, paying for repairs on many affected Odysseys, but not all.
A quick check of Honda forums shows there are still complaints about excessive oil consumption. The VCMuzzler seems to make it about 75% better which is a huge improvement.
Talking to the BAR in CA, it seems that Toyota has similar problems, but not as severe. In both cases it's caused by rings on the pistons to reduce friction and improve fuel economy that are letting oil seep, plus software that turns off cylinders that aren't needed in highway driving.
