Well, my older son has been driving my parent's 2011 Accord since May, for his Pharmacy School internship, mainly for a 100-mile commute every day. On Monday, he called and said CEL came on and car started running rough, but he made it to an out-of-town destination. On Tuesday he got the trouble code read, P0303 - Cylinder #3 Misfire. I was about to go buy a coil and plug, drive to where he was and fix it, when I remembered that my parents had some misfire repair work done previously. So I called the local Honda dealer, and they said that they had replaced the plugs and re-flashed the PCM as part of a recall in March 2017, but there was a second procedure if the first attempt "didn't take". I met my son at the the closest out-of-town Honda dealer, told them about his experience, and they starting talking about tearing the engine down and basically doing a re-ring job. Huh? For cylinder misfire? They assured me it was a warranty / recall issue. I googled this after I got home and found out about Honda TSB 13-078 "Warranty Extension: MIL Comes On With DTCs P0301 Through P0304", that extends powertrain warranty to 8 years from in-service date, unlimited mileage. Wow! Apparently Honda has had issues with VCM in 2008-2012 V6 Accords. Sad, because the car only has 72K miles, but is still within the warranty period. Hopefully the repair will correct this issue. The car is my parent's secondary vehicle and has been well-maintained, but as I said, my older son will be using it until next Spring. Anyone else have similar experience / offer any tips? Thanks.
