2.4L Engine noise on cold start-up, CRV AND Accord
Dear Honda,
I'm a new owner of a 2014 Honda CRV EX. This is the 4th Honda vehicle and
5th Honda product my family has purchased. My Mom has also purchased a 2014
CRV EX-L, this is her 3rd CRV.
I purchased another Honda due to your reputation for reliabiliy and quality
control. You also have a reputation for stepping up to take care of your
customers in every possible way, which I really apprecaite.
To say I'm extremly dissapointed that my brand new, 2014 CRV with 200 miles
on it has an engine noise on cold-start up would be an understatement. If
you search You Tube, for "2012 Honda CRV, Cold start noise" you will hear
exactly what noise I'm referring to. Through research, I've found that this
problem affects all recent model 2.4L engines, CRV's and Accords. It's a
metal on metal sound, like a grinding noise, or to me sounds like the timing
chain is hitting the valve cover.
I called my local Honda dealer who told me this noise is normal and that he
could go out on his lot and start several random 2.4L Accords or CRV's and
they would likely make the noise. He told me his personal 2013 Accord 2.4l
does it, as does the dealershiop's general manager's new Accord! It lasts
for a second or so and then is gone. Clearly this is a known problem. I also
heard videos of several 2008 Accords making the same noise. I have 23+
years of mechanical experience working on a variety of makes and models and
I can ASSURE you the noice is NOT normal.
The noise is brief, lasting a second or so, and if you get in the car with
all doors closed you cannot hear it. You can only her it if you crank the
car with the doors open (I had to warm it one day after a snow event which
is the first I heard it), so a LARGE number of people probably are totally
unaware it's even occuring.
With Honda's reputation for quality and reliability, how in the world has
this problem gone on for the past 6 years without Honda getting to the root
of the problem and addressing it? I understand the problem gets
progressively worse and eventually will stretch the timing chain. I cannot
believe that with all of your engineering and R&D, the cause of this noise
has not been identified and a repair outlined.
I have found that in the morning, if you cycle the ignition key to the on
position, then off for a moment, then back on and leave it on for a few
seconds before cranking, it sometimes does not make the noise. I'm not
intimately familiar with the 2.4L engine so I'm not sure what issue that
would point towards, but hopefully that may give your engineer's a place to
start. Occasionally it will not make the noise if I turn the key on, then
wait a few seconds, then crank, however when I tried that tecnique after
work yesterday, it still made the noise.
Honda, if you want to save your reputation for quality and reliabiliy,
invest the time necessary to identify the exact cause of this problem and
institute a re-call for all models affected. I really like my CRV, but after
investing $26,000+ on a new vehcile, to have one that makes engine noise
just because it's cold out when you first start it, is completly
unacceptable.
Thank you.
