Our reliability stats for the 4Runner now include owner experiences through March 31, 2014, making them nearly a year ahead of other sources.
Repair frequencies, in terms of repair trips per 100 cars per year:
2013 4Runner: 7, low, small sample size
2012 4Runner: 19, low, very small sample size
2011 4Runner: 10, low, small sample size
2010 4Runner: 43, moderate
We have two additional statistics, "Nada-odds" and "Lemon-odds", to indicate the percentage of cars with no repairs in the past year and those that required 3+ trips to the repair shop:
2010 4Runner: 69, < 1
