The engine on my 07' Rav4Sport blew up at 86k miles. I had all repairs, replacements, even oil changes performed solely at Toyota dealerships. Something shoots out from inside the engine while I'm driving on the fwy one day, spews ALL of the oil out from inside, about 6-8 quarts, my rear wheels kicking that sludge back up onto that stupid rear gate with the tire on it while I desperately try to exit the fwy. I get it towed to the dealership where I had gotten an oil change 6 days prior; to find that there is a 3 sq inch hole in the bottom block and that I need a new engine. I take this up with corporate, aaand they're nice enough to offer me $1k toward the purchase of a new lemon.
I quite liked it when the engine worked normally and did not experience any other sort of malfunction. Which in my 6 years of ownership has amounted to about an hour and a half.
