well, driving the **** out of it WILL ruin them quickly...i have seen some factory replacements last only 15,000 before giving....it's uncommon in hondas, and especially accords, but it's entirely possible....out of 40k, u would have had to run the **** out of it for 39k, but i'll admit i'm capable of doing it.....seems like they would warranty it though....have u checked the recalls for your model.....
