Maybe I am lucky but the class action misfire codes on my 2011 Crosstour first appeared on the exactly 8th anniversary of delivery of the car. This was a Friday night so it was Monday before I could call dealer. Despite my argument that the car failed while the extended warranty was in affect they will not pay under the warranty extension because they say work was actually done after warranty expiration. So I am on the hook to pay for plugs and software update per service bulletin. What is experience with this issue. Does replacing the plugs and the software have a chance of fixing the issue or can I expect this to progress to replacing rings?If Honda is not going to stand behind repairs I just had done, it does not look good should the misfire reoccur and the answer is a ring job. Disappointed in Honda in how they are bailing on this.
