    Honda owners would have been contacted by Honda UK for this urgent safety recall. Majority of the Accord owners in the UK may have had this update as part of routine service. This post is for those members not aware of this due to the actual owners of vehicle (lease) may have not informed their drivers.

    The affected Chassis code for this recall are CU3 and CW3 of production years from 2009,2010 & 2011.

    Symptom

    Engine oil level increased due to dilution by diesel fuel.Engine speed may increase and the engine may not stop when ignition is turned off.

    Cause

    The engine ECU software controlling post injection, required for DPF regeneration was incorrect, causing a deviation between estimated and actual oil dilution rate by fuel. As a result engine oil level can increase and, if beyond a critical level, may cause engine speed to increase and eventually stall due to internal damage.

    The Fix

    Update engine ECU software. Dealers update the card ECU using HDS software and rewrite ECU using the ECU rewrite software.

    Affected VIN Range


    JHMCU3***9C000001 - JHMCU3***9C999999
    JHMCU3***AC000001 - JHMCU3***AC999999
    JHMCU3***BC000001 - JHMCU3***BC999999
    JHMCW3***9C000001 - JHMCW3***9C999999
    JHMCW3***AC000001 - JHMCW3***AC999999
    JHMCW3***BC000001 - JHMCW3***BC999999

    As part of the change the car will receive a oil filter and oil replacement with no extra charge for this. So if you car is due a service be mindful the dealer does not accidental charge you for an oil change.


    If they do please politely make the service manager aware of their mistake and refer them to this TSB.The entire recall will take the dealer over two hours provided your car battery is holding a good charge.

    I was one of those drivers that the lease company didn't bother to tell. However, since this work was carried out, my fuel consumption has increased noticably.

    To be fair it was only averaging about 42 MPG before but has now dropped to 39 MPG (on mainly open A roads and driven carefully).

    Is it only me?

    Hi and Welcome to AOC,

    Happy the info has come to your advantage,the safety recall update is worth the little extra fuel it consumes but it will improve.

    Weird.

    When mine was done, fuel consumption went down. By a BIG margin.

    I hoped for an improvement and thought that maybe it would be in line with the newest model which has good MPG and slightly lower emissions. Not sure how much this is likely to improve with time as the work was carried out 4000 miles ago.

    I have also tried using premium fuel but that makes no difference either.

    On m-way runs, which I do a lot of each day, I routinely, at WORST hit about 60mpg. Then it goes up to about 70 or 75mpg, give or take a few. I'd go back to the dealer and check you have had the required software ECU updates as needed.

    Car is booked in for a check later this week.

    Incidentally, I did a manual tank test and had better results. Maybe its just the trip computer that is confused. I used just over half a tank and had covered 400 miles and it only took 40 litres to fill (45.4 MPG) but the trip computer said 39.1 MPG from the same original fill. I have that thing set up that resets Trip A every time I fill and virtually brimmed the tank so I am a bit happier that it's a bit better in real life than the trip computer says.

    Still being checked by the dealer though.

    Good news I doubt the dealer will find anything out of the ordinary. Apart from full service it's little you can do get higher mileage.

    If your car has never been to HONDA Dealer then it would be outstanding numerous updates ,IT is impossible your car doesn't have any outstanding updates.

    Have you crossed check you VIN number matches to the one stated in the TSB?

    Just a reminder for all new members who will be looking for a new accord over the next few months , please look up the VIN numbers on the Honda recall website to confirm this has been applied.

    Yes Mark Honda UK change the Owners section with the new servicing scheme and the URL have been changed.

    I see no issue renaming the page to Updates and Recall , the masses believe anything on the car which the manufacturer fixes is a recall when its not.

    It good they have made that clear distinction for a better customer perception and education.
