hi all I'm new to this forum but not toyota , I just bought a used 2010 4runner sr5 from a small dealer and was wondering what are some of the problems that happen with these trucks? I am asking because after my 30 day warranty was up on my tacoma i discovered a oil leak on the timing cover, had I asked the people of tacomaworld,i would have known and would have had them replace the seals under the warranty.
