#1 of 19 2009 Honda Accord Misfire by fanofmsu

Nov 30, 2009 (6:32 pm)

I've had my 2009 Accord EXL V6 into the shop 5 times now due to a misfire on cylinder 3 (code P0303). I've had a fuel injector replaced, the engine computer replaced and most recently, the valve seals (which was supposedly the final solution although I experienced the problem yet again). Honda couldn't find anything wrong with my car after the last breakdown and actually gave me my car back with no repairs. I lobbied Honda to repurchase my vehicle but instead I've been left to wait for the next breakdown for Honda to take additional action. I'm disappointed with Honda beyond words. I've heard from dealers of some similar misfire complaints and I wanted to warn potential buyers. Has anyone else experienced this?

I have the same car and having the same issue. It 1st happened in December 09. They cleaned the plug and reset the code. Told me they had another car in the shop with the same issue. Same model and all. He did say it would come back to schedule an appointment -I was going out of town for a while..Anyway-Just yesterday the dashboard lit up again ( VSA light, Exclamation point in Triangle and the engine light). Called Honda and they said they needed to do a valve job that the valves were overtighted at the factory...I'm set up for Monday. I'd like to know how you are making out? Otherthan the light the car runs fine. I'm not getting a typical misfire feeling from the engine. Getting a valve job on an engine with only 15,000 miles on it is a abit disturbing...

It sounds like you're experiencing something different is your car isn't running rough after you see the check engine light come on. My dealer had seen several instances like mine (misfires, and only after long drives).
 
Honda refused to buy my car back from me so I had to file a lawsuit and am finally making some headway. The service manager near me was honest and said he doesn't believe that Honda truly knows what's causing the misfire problem. I wish you the best of luck and let me know if you have any more troubles.

Adding to the info - have a 2009 coupe with 24K miles. Yesterday coming home from work, got the flashing engine light and distinct car shudder. Took it to the dealership because it's still under factory warrantee and lo and behold, Cyl3 misfire. Repairing today, don't know exactly what they'll do (depends on what they'll say they found, I imagine) so more to come. Was told that Honda has a new "kit" because it's a common problem, but don't know what the kit contains. Thanks for the info sharing all.

I had the same Issue, Here is what was done to correct my problem, Taking this directly from my work order. -
  
'Inspected spark plugs No. 1 through No. 4, Found the No. 3 spark plug fouled. Replaced the No. 3 cylinder spark plug and performed the power train control module software update as per Honda Service Bulletin No. 10-033'
Seems to be a very alarming common problem, I still think it's related to the VCM

Have you noticed improvement since you had the service performed?

I am newcomer to this problem. I would like to know from any of you had any positive results retaining legal help. In November of 2010, I had my VSA light go on, exclamation triangle light, and check engine light all on. I took it to dealership having only 34,000 miles on it. My car was stalling as I was driving it. They told me that it was a fuel injector and needed to be replaced. Also said my battery also needed to be replaced. After replacing both the car still was not driving well. With many back and forth consults with technical support, it was advised that the dealership to a complete tear down of the vehicle. Ultimately, the dealership had informed that they would be overnight express a cylinder head assembly kit. After nearly having my car at the dealer for two weeks, my car is still not sounding right. It was left with engine noise. The dealer refused to extend my warranty nor buy back my vehicle. What else can I do at this point? Any suggestions??? I appreciate any feedback.

I'd recommend that you research your state's lemon laws and consider retaining a lawyer. Typically, lemon law lawyers don't charge their clients (they get paid by the automaker). It's unfair to be stuck with a rebuilt engine when you purchased a new vehicle. Typically, your car won't run as smoothly as when it was new and when you sell your car you're going to get less $ due to your rebuilt engine. Honda has really screwed up and they need to be held responsible.

I have had the same problem twice. The dealer replaced the spark plugs. But it happened again. I am very dissatisfied with this car. It is also impossible to keep the tires balanced.
