[CU2] funny noise from the engine when slow accelerate

[aaronng]

Can I assume that its the 4cylinder version not the V6...seems that Honda may have a rather large issue on their hands.

Seems like a drivetrain issue if it is happening on different engines as well.

You guys with pinging, can you confirm for me if the pinging gets worse with RPM or does it get worse with increasing speed.

Yep it is 4 cyl auto

Here is a good article to read about other possible causes of knocking or pinging.

my 2007 euro old model pings too. the Honda dealer said there is nothing wrong with the engine .It is not unusal.

"Mild or occasional detonation can occur in almost any engine and usually causes no harm. But prolonged or heavy detonation can be very damaging. So if you hear knocking or pinging when accelerating or lugging your engine, you probably have a detonation problem."

As quoted from the above article, maybe what you are experiencing in your cars is normal and you just have to put up with it.But I know how you are feeling - it would be better to have no pinging at all.

Detonation can happen, but if your car is spec'd for 95RON and you put in 98 or 100RON and it still detonates, then it is not normal.

I still doubt that this is detonation. My opinion is that there is a sound from the gearbox which sounds like detonation.

i got the same problem.
Its definitely not fuel problem.. I've been using 98RON Shell, Mobile and BP for the matter and still have the rattling problem.

A/C on or off doesnt matter. Rattling still there.

Only happens with low speed take up. (sounds exactly like when you're in the wrong gear) Noise is coming from the driving side. Clock is sittting on 4000km now. Didn't notice until releasing cos too focus on my steering problem I had (lumpy steering) and also perhaps I have the music pumping before i drive so didnt hear anything.

I will contact Honda service this week. I'll keep everyone posted.

Well they fixed the rattle in the parcel shelf, turns out exactly what I told them it was, ie the metal layers where the spot weld has not gone all the way through...though it took them most of a day to locate it...and the rattle in the door sometimes pops up, I think its the wiring loom in the door, so I will fix that myself...

But alas, the engine still rattles and at times appears to be getting significantly worse, one thing I can say is I have requested a fix by the end of the month, after that I am going to have to take another course of action...or two.

Regarding the so called engine pinging problem, on my advice a family member got a CU2 auto 2 months ago and immediately noticed what he described as engine pinging. After several complaints to the dealer they asked to have the car for a day to re-program the computer. He has told me that for the last 2 weeks he has had no further problems with pinging. Pls note this is second hand information.

Hi Bob,
Any updates??

Any good news from anyone with the same problem?? I have not heard of anything from dealer or Honda Aus so far.
To those guys who sent their car for inspection in Sydney months ago, just wondering whats the result and follow up.

I sent an email last to General Manager and copied the sales rep who sold me the car along with the sales manager and the service manager. To my suprise they got back to me a couple of days later.

They told me to take the car this Wednesday for a check up. They have also offered me a replacement car while they diagnose the problem. Fingers cross, they give me a type R!!!!

They will be looking at my lumpy steering problem I had form day one.

Fingers cross they fix everything and throw in some freebies while they at it for the inconvenience they have caused me. I'll keep everyone posted with the results.

I was in Perth last week and went with a friend to a dealer on the Leach Highway. My friend was interested in the CU2. We chatted with a youngish salesperson who seemed to know his stuff. Then I asked him directly about whether the pinging problem had been solved. He paused and then acknowledged that there was a pinging problem. But then he went on to say that Honda had solved it as they had discovered that owners had actually been fuelling up with 91 RON ULP instead of 95 RON PULP.

Well, I thought to myself: 1. He confirmed the existence of the pinging problem; and 2. He still wanted to sell my friend the CU2 no matter what.
