Honda Civic Hybrid

Hybrid car manufacturers charge thousands of dollars extra by promising improved gas mileage.  They also promise to replace defective parts during the warranty period.  But numerous published reports suggest that Honda is breaking its promises to consumers who buy its popular Civic Hybrid model.

The problem is with the Civic Hybrid’s expensive high-tech battery (known as an integrated motor assist or "IMA" battery).  Honda has admitted that the IMA batteries in its 2006, 2007 and 2008 Civic Hybrids "may deteriorate and eventually fail" prematurely.  But instead of replacing the defective batteries under its warranty, which would cost an estimated $3,000 per  battery, Honda has tried a cheap fix, installing a so-called "software patch" in the Civic Hybrid’s computer.  This undoubtedly saves Honda money.  But hundreds of consumers have complained that Honda’s quick fix drastically reduces their Civic Hybrid’s gas mileage, which is, of course, a major reason they bought a hybrid car in the first place.  As one consumer put it: "Thanks to Honda’s battery-saving update, my Civic Hybrid is now a standard underpowered Civic.  I paid an extra $5,000 for the hybrid feature." 

Honda has sold hundreds of thousands of hybrid vehicles in the United States and Canada.  If you own a 2006, 2007 or 2008 Honda Civic Hybrid, please contact us to discuss your rights.

    I own 2006 civic hybrid, and recently realized that my battery must be broken, actually my friend suggested that, since I am not a very techincal person. I really don’t know when the my warranty expires. Please let me know, if you have any information or updates about that matter thank you.

    We have a 2008 HCH with the common IMA problem. The amperage suddenly disappears. The IMA gauge goes up and down like a yoyo and the fuel mileage drops precipitously. We go to the Worlds largest Honda dealer. The service writer thinks I am a moron. The dealership checks the voltage on the IMA circuit.He tells me the system is fine and gives me a copy of the readout. I say “Thank you” and leave. I was a licensed electrical contractor in California. I know they did not mention the key information on the amperage. I am an old man. I must have looked simple or stupid. This happened in June 2011. ON 09/20/2011 I returned to the same dealership. I handed him the letter that follows:
    September 19, 2011
    Vehicle ID JHMFA36218S012559
    Date of Purchase May 6, 2008
    OWNER: PEARL KAPLAN 1201 SW 128th Terrace, Apt 314, Pembroke Pines, FL 33027
    PROBLEM: The IMA system is not working properly. The system does not maintain a charge. The Service Writer Mark has the voltage checked in the batteries in the IMA. The problem seems to be the amperage.
    Lately when we start the car in the morning, the IMA system does not have enough power to start the car. To start the car the starter motor must engage. Our mileage has dropped roughly 5 miles per gallon.
    The IMA system recycles two and sometimes three times in the day. The gauge drops to 2 segments at startup in the morning, every morning. After we drive 2 or 3 tenths of a mile to IMA gauge will rapidly go up to 7 or 8 segments.
    In traffic in Pembroke Pines with the AC on, if we stop at 2 consecutive traffic lights, at the second light the IMA drops to two segments and no longer assists the engine. When we use the AC we set the fan at its’ lowest setting.
    The dealership does the following software update:
    OP#1255B2 Update: PGM-FI software
    IMA battery software
    A/T software
    start clutch learning
    CKP learning
    PCM idle learning
    The Service Writer gives me a page from the 9/9/2011 update bulletin.
    Off I go happy as a lark. I drive 2 miles and the vehicle displays the same idiosyncrasies as before.

    Thanks California for adding bite to warranty coverage. I have 94K on my 2007 HCH and it is just beginning to show weird charging habits (fully depleting and recharging multiple times in a single drive freeway drive cycle) and yes there has been a signifigant decrease in fuel mileage (43mpg avg to about 39.2 now, same tire brand–michellin xv4 HM, etc.) Hearing the 8yr/80k warranty I was almost floored because I thought it was higher and even the settlement added time/mileage, I was out. Fortunately, California vehicles (AT-PZEV’s) get 10yr/150k mile warranties, but since the reprogram my car is less efficient (mileage and cost wise), more polluting than it was b4 August last year…
