See the below link and table from that publication. Because these are passenger automobiles under 6,000 gross vehicle weight, there are limitations on annual depreciation. For your Odyssey, purchased in 2005, depreciation was taken as 67.04% of 1,675 (from table) = 1,123. I believe this is too high because generally the half-year convention (562 instead of 1,123) should apply in the year of disposition (I'm not sure for listed property, and am too lazy to confirm).
It appears to me, your accountant did not answer the questions O,P, and Q for your Pilot, and therefore there was no depreciation taken on that return for the Pilot. I believe your 2011 depreciation on the Pilot should have been 11,060 x 66.67%. Might be worth a deeper dive into the proper calculations and possibly amending your return.
For your 2014 return on the Pilot, from the table, a car placed in service in 2011, 4th year maximum is
1,775 x business use %.http://www.irs.gov/publications/p946/ch05.html#en_US_2013_publink1000107703Maximum Depreciation Deduction for Passenger Automobiles
