My 2.5L sounds similar to that, except for the starting up sound and not quite as loud... It just started doing this Yesterday (2/12/12).

Does it sound like normal after it is fixed, also how long time does it take to get it fixed?

 

Final update...I hope. Service dept. called today and informed me they swapped out the serpentine belt and the sound went away both on the lift and a test drive. Wife and I picked her up a few hours ago and ran a few errands around town on roads with speed limits varying from 25 to 50 and didn't hear the sound at all! Service advisor feels that the belt was stretched from the faulty tensioner which they replaced two weeks ago. At that time though they wouldn't cover the belt under warranty ($55) so they re-used the original belt and sound persisted. Today I got a new belt for free and no more noise!

So any other 2.0 owners with an intermittent rattling/ticking coming from the right front tell the dealer to check both the serp. belt and tensioner.

 

Does it specify which models and from what year to what year?

 

I'll have to look but I think it was just 2010s any model

 

on a cold start you may hear normal noise like a light tap for a minute or so, cam gear noise is usually very loud on a cold start happening for just a moment or a tap at about 2k rpm, sometimes even having noise when reaches operating temp. mazda isn't the only 1's with cam gear issues for vvt either, rather shame.

and i think this is an owners extension for customer support warranty. 2007-2010 ms3/ms6

 

See I figured especially since I upgraded my fp but I'm just curious

Edit: VVT Timing Chain going bad? - YouTube

I'm having a similar sound coming from my car but not as loud. Did you get fixed by the dealer under the warranty? If not what's involved in replacing it for a better unit?

 

This recall is for the 2.3L Turbo only.

 

Um no its not

 

Bump for anyone else out there that has had this recall done or may know more about it. Our 2.0 started making this noise a few weeks ago but it has been intermittent. Wife heard it first while driving at highway speeds and I finally heard it on Saturday (while idling) after running some errands around town.

Noise sounds dead on to the first youtube link in this thread but if it was the vvt chain wouldn't the noise be there all the time and not random?

 

does ur engine sound like this?

i posted a thread back in nov 2011 when i just got the car and ppl say its NORMAL? Can anyone confirm this?

here is the orginal thread:
http://mazda3revolution.com/forums/2010-12-mazda-3-engine-performance/9149-engine-sound-2-0l.html


this is 28,000 miles later ( TODAY )

 

Yes, that is similiar to the sound I'm hearing. Ran out for lunch and when I pulled into the parking lot at work I heard the noise so took a vid with my phone. Let it idle for a bit and grabbed a co-worker to listen as well and after about five minutes of idling it went away??

*edit - Just read your original thread and if it is normal, why is is something my wife just noticed almost three years into ownership?

 

Anyone have the recall info? That way we can look it up.

Mine (on cold start up) idles high up to 2K rpm, but with the exhaust growl on my MS3, rest of the engine sounds finds.


If i turn it off after 30 mile drive, there is a little tap tap tap tap/tick tick tick noise on the motor (I haven't heard any other MS3, so I am not sure if its normal or not).

 

Mine does the same thing in the morning and when I shut it off.

Stopped by the dealer tonight and played the video on my phone for the tech. Said it was tough to tell from that and made an appt to take a look at her next Friday. Don't think my issue is VVT though since it's not happening on a cold start up but rather when the engine is warm and at higher speeds. He also said he hasn't heard of a lot of VVT issues on NA 3's unless the oil was never changed or run at low levels. Did say he has seen tensioners issues though....hmmmmm

 

can u post the video u showed them? My car is at 28k miles and I wanna bring it in to get it fixed if its possilbe before the 36k mile warranty.

 

Natural aspirated vs Forced induction.

Mine is under powertrain warranty too. I get the usual Mazda tick at idle, that I Have had on my miatas too. I have no idea what this noise is.....that we are talking about..if iknew I could see if i have the issue.

 

Are the 2.0L NA or FI?

^^^ FI is 2.3 Turbo

 

Well I compared my idle to another mazdaspeed owner on the forum, and it sounds the same, so I guess I am ok for now.

 

Yup and just logged on to post up. They could not duplicate the sound, of course, but again said they rarely see the VVT issues with the 2.0s unless there is obvious negligence. Did say they have seen issues with the belt tensioners and mine had some play in it so they replaced it in hopes that would solve our issue. After picking the car up and following my wife home, she said she heard it on the 1.5 mile drive home. So, need to call them again and this time going to ask that I take a ride with the tech.

 

Update....taking the car back in this Thursday night to take a road trip with the tech to point out the noise. Last night I heard it everytime I started from a stop, then it would go away and come back when I was on the gas at around 40mph. A few times I heard it when on the gas at 25 and 30mph. Goes away when I take pressure off the pedal? Tranny issue?

 

Is it a Chu-Chu sound? Or a ticking?? I'm trying to see if mine has the same problem but it's kinda hard to determine with hearing ur car personally. Maybe take a video while ur in ur car?

More of a ticking sound and I'll try in the next couple of days. Will have to have the phone ready while driving since it doesn't do it all the time.

 

My car has a slight tic to it. About like all the videos except that one that was really loud. I'm sure its nothing to be concerned for.

 

Dropped the car off earlier tonight. Tech took a ride with me and when I pointed out the noise, he made some notes and said he hadn't heard anything like that before on the new 3's. So I'll wait to hear from them tomorrow.

 

Good to hear back from you. Im curious to what his observation and diagnosis is gunna be. Keep up us posted!! I'm trying to see if my car makes a similar sound but not too sure :-/
