Honda has issued a Service Bulletin on April 25, 2012 for many Civic Coupes & Sedans.

'Engine Stalls During Cold Start'

SYMPTOM
If the accelerator pedal is pressed during a cold start,
the engine may start, then stall.

PROBABLE CAUSE

The PCM misinterprets the amount of fuel needed to
start the engine, which causes it to stall.

VEHICLES AFFECTED:

2012 Civic 2-door M/T:
From VIN 2HGFG3A..CH500001 thru
2HGFG3A..CH541694

2012 Civic 2-door A/T:
From VIN 2HGFG3B..CH500001 thru
2HGFG3B..CH541795

2012 Civic 4-door M/T:
All VINs starting with JHM
From VIN 2HGFB2E..CH500001 thru
2HGFB2E..CH559766
From VIN 19XFB2E..CE000001 thru
19XFB2E..CE059576

2012 Civic 4-Door A/T:
All VINs starting with JHM
From VIN 2HGFB2F..CH500001 thru
2HGFB2F..CH559400

From VIN 19XFB2F..CE000001 thru
19XFB2F..CE059017

From VIN 19XFB2F..CE300001 thru
19XFB2F..CE349793

2012 Civic Si 2-door:
From VIN 2HGFG4A..CH700001 thru
2HGFG4A..CH702956

2012 Civic Si 4-door:
From VIN 2HGFB6E..CH700001 thru
2HGFB6E..CH703424

CORRECTIVE ACTION:
Update the PGM-FI software.

Looks like it's just a simple software update that will be covered under warranty. I havent noticed anything on my 2012 Civic Si but i'll still get the update.

Na, seems pretty harmless. I usually let my engine warm up until the cold light goes out before I start driving anyway.

Has anyone had this problem on here? Any stalling shortly after start-up?

Sounds like it means pressing gas when trying to start it.

I haven't had any problems but I am in the range. I let mine run until the cold light goes away, hasn't stalled on me yet.

The problem is that it stalls before starting. ie. before you can even allow the engine to warm up, it stalls.

Who pushes the gas to start a modern EFI car anyways? Havent had to do that for what, 30 years almost. Maybe this is a smokescreen to fix the rev hang :) yah right...

Yeah, the way they word it, it sounds likeit only affects people who manipulate the throttle while they are cranking the engine, which they should not be doing. Shouldnt the fix be 're-train driver'?

I noticed it twice when it was snowing out. I never pressed the gas. I have the 2dr manual. I thought it was weird and just a new engine getting used to being new. lol. Hasn't happened since. Until I see an actual recall from Honda I think I'm not gonna mess with it.

By the bulletin, it sound like you arent affected since you don't touch the gas. BTW this will likely never be a recall, just a bulletin so you'll need to complain about it yourself.
