At the 2005 model year Honda retracted four down towing for ALL Honda's but the CR-V. We had bought a 2005 Ody in Dec '04 after getting it in writing, on Honda letterhead, that it was towable four down. After some back ans forth with Honda legal dept they cut us a check for about $2,200 to pay us for the towing equipment we had installed. Used the money to buy a KK-460 dolly and used it for a couple years, (till it was out of warranty after the extension). Now towing it four down with no problems other than having to run a charge line to the battery.
I was thinking of replacing the Ody with a 2016 CR-V, but Honda lost my business now.
