Done and Done. The mechanic was going to take photos yesterday and I already have a case number with Honda Customer Service.Take pictures of the damaged parts and head over to the dealer and they if they don't make things right then call Honda Customer Service.
Yeah, I remember your prior post that the repair was incorrect. It does appear you were correct.CR, I remember your past threads on this problem. I said in response to your having complained that you'd had to have this repair done a second time that, IMHO, the first repair had been done incorrectly. Clearly, that's the case.
You should raise hell, but I doubt that you'll be reimbursed without a lot of additional effort on your part. If you have a small claims court process in your state, you need to work it for all it's worth. I hope this works out for you.
Mine didn't start day one, but close. My first replacement came at about 13K, the second around 20K. I'm now at 40 1/2K. I'm stumped; I'm not a mechanic, but I'd agree that it seems like it would be a lubrication issue. I've run conventional oil, synthetic, synthetic blend, 5W-20, 0w-20, Castrol, Honda, Pennzoil, Mobil1 and no considerable difference. I will say the sound was the worst with the 0w-20 full synthetic. The only constant is cold weather. If it's about about 40 degrees, it likely won't rattle. I've never heard it in the summer or any relatively warm weather. I can't believe this is "normal", if it were "normal" I would think it would do it every time it was cranked regardless of the weather. I know vehicles can behave differently in cold weather, but still. But again, I'm not a mechanic. This is very frustrating.My 2011 EX I4 has made a metallic ruckus when cold since day 1. 22k miles later, and I haven't had any issues other than the noise which seems to quiet down once the engine warms up. I wonder if the timing chain on these engines is just noisier than usual when the engine is cold? I would say it's some kind of lubrication issue on a cold start, but I'm sure that would've led to major issues long before now if that were the case.
That said, I had a 2010 EX I4 prior to this one and I honestly don't recall it ever making the same metallic grinding sound during warm-up that this one does. I honestly don't think my issue is the VTC, as I've heard sound clips of that problem and it sounds much louder and more severe than my idle rattle and it only happens for a second or two versus mine which lasts for minutes.
The one key difference between my 2010 and 2011, besides whatever friction-reduction measure they implemented in the newer engine's internals, is the engine oil. The 2010 used Honda 5W20 dino oil, while the 2011 uses Honda 0W20 synthetic. I wonder if there's a correlation between the sound and the oil used?
I really don't know what could be causing this noise. The dealer gave me the usual "it's normal" response and sent me on my way. I know this doesn't help you at all, but if mine breaks down, I hope it does so after I turn it in in April...
