Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety. Notes: The 2006 Civic Hybrid has an engine that doesn't shut off when it should and electrical components that shut off when they shouldn't.

Honda cvt transmission slips when starting out, especially when starting uphill. Have taken to Honda and private mechanics no solution. This thing slipping when I try to start out into traffic can and will cause an accident someday.

While driving at about 20 mph, the transmission disengaged from the engine. When accelerator was pressed, the engine would freely rev to the redline but there was no movement of the car. The car was going up a hill when this happened. The car was rolled backward, almost into traffic at a busy intersection. Car had to be towed to the dealer. At the dealer big island Honda, they did not experience the malfunction and could not solve the problem. We drove the car home. The next day we drove it again and the problem flared up again. This time we managed to get it to the dealer in time while risking our lives to get it there. However, this time the issue was discovered and the car wasn't released to us when they recognized that the issue could indeed contribute to cause a catastrophic failure shutting down all engine operation while driving! I was shocked since I am a mechanical engineer who understands catastrophic failure in machines. They took two weeks to diagnose issue and replace computer chip. Is this a manufacture defect, design failure, or life endangering malfunction?

I'm a Honda Civic hybrid owner (2006). I have not reported the lack of acceleration to my dealer, assuming that was the low power of the car due to the hybrid nature. The lack of acceleration at times when it's needed has put me in unsafe situations. Additionally, my hybrid does not consistently auto stop as designed.

Honda performed an ima software update on 12/22/2010. Since that time the availability of electrical assist has been greatly reduced. Even when the battery reads full, I cannot be sure that electrical assist will be available, or, if it is available, how long it will last. Several times it has suddenly failed in the middle of a merge or lane change.

On at least four occasions, once while moving at about 30 mph, the entire car shut down. The gas engine shut off, power steering and brakes went dead, and the dash went blank. I had to place the car in park, and then remove and reinsert the key in order to restart. This has happened once, though not while moving, since the ima software update.

Cvt is slipping, hard to power up hills, doesn't kick in after a stop and sometimes stays on or speeds up around corners. Just had the transmission oil changed and problem has not improved.

Summary: My 2006 Honda Civic hybrid received the integrated motor assist (ima) software upgrade in 2010, since then vehicle performance is unreliable. If the car is not used for about 10 hours or more I.e. one day the ima battery will drain in less than a mile of leaving my home the next day, on a level roadway. This leaves me with the gas engine only and driveability in traffic suffers a lot with slow acceleration and poor overtaking capability to the point of being dangerous. After about 2-3 miles the ima system will start to indicate charging and within a short distance the ima indicator will suddenly jump from 3 bars (low) to 8 bars (full) in a matter of 3-5 seconds. This is not normal nimh battery behavior my Honda dealer says they cannot do anything because the ima system light does not illuminate (obd does not show a fault). In my opinion from driving the vehicle the ima software upgrade has done nothing to solve the basic problem and has reduced my economy by about 8 mpg!.

The integrated motor assist (ima) battery is failing prematurely on my car, the assist works sporadically. When passing traffic on the highway I have to really mash the gas pedal to the floor, because the assist is absent for lack of power. Honda installed a software fix(bulletin 10-034) that greatly reduces the battery ability to function at full capacity, so they could make the battery last longer and not have to replace them under warranty. I get the code P0A7F (one of the blocks in the battery pack has deteriorated: Its dynamic resistance is too high) on my car computer. Honda erased it manually and sent me home without replacing my ima battery. When coming to a stop the car surges as I make a complete stop, because the car is regenerating power to replenish the spent battery. The so called patch 10-034 is really making the car unstable to drive, the engine reeves very high without much power produced in passing or entering highways situations. When the car was working fine, a little touch of the gas would have been enough to pass traffic or climb steep hills. Now the assist only works sometimes and keeps me guessing if I will have enough power to pass or not. The ima battery is definitely not up to the job.

Bought this car new. I won't even go into the ridiculous 49/51 mpg window sticker that is a blatant lie but that does play into my complaint as you will see. Honda, after receiving complaints about the battery pack and having problems with it, has this brainstorm to reflash or reprogram the computer/battery pack as part of a recall this past year. This was done at my last oil change. Prior to that time my sole complaint with my car was that the mpg averaged about 35mpg period. Since this last recall and reprogram not only has my fuel economy gone down but the performance of the car is essentially unsafe from a stopped position. Let's face it, the car never was a nascar but on the other side of the coin it was not a golf car either. Now when starting out from a stopped position, whether at a stop light or anywhere and whether the motor has shut off or not, the hybrid is so bogged down that I honestly believe my golf car accelerates better and more quickly. Let's set this straight too. I'm 41 and not trying to drag race I'm merely trying to drive the car in a normal safe manner. At times it feels like the car is going to literally die in the middle of a turn or intersection which can be a bad thing once you commit to a turn and there's a 53 foot 100,000lbs of fun coming in your direction. Honda has gotten away with ignoring my complaints about the hydroplaning of this vehicle, the ridiculously low fuel economy, and now they will likely do the same with their attempt at making their battery last longer which has made the vehicle less safe for me and my wife and kids. This "recall" was nothing more than a battery life extender to protect Honda's wallet. How about replacing everyone's battery once for the life of the car? that'd make sense to know...the guy that shelled out $24,000 for your car expecting to receive mid to upper 40's in fuel economy. Fix it.

The integrated motor assist (ima) hybrid system loses power with no known precipitating factors or advance indication of failure. The vehicle will immediately reduce power train output prior to the dash gauges indicating a near-complete loss of ima battery charge and function moments later, with only the internal combustion engine providing motive power. Within 3-4 miles of driving, the ima battery charge, as indicated by the dash meter, will then immediately jump to a completely full level in a similarly unexplained fashion. Independent of these transient but regular failures of the high-voltage hybrid system, the vehicle functions as expected. Currently, I have documented over 160 instances since 4/22/11, occurring an average of once every day the vehicle is driven, increasing to 2-3 times daily since mid-November, 2011 (data available on request). Symptoms occur independent of ambient temperature, nature of drive (high/low speed) and despite changing the 12 volt battery and disconnecting or turning off all power accessories possible. Following a satisfaction campaign by Honda in late summer/fall, 2010 that involved a software update installed at a Honda dealership and replacement of the DC-DC converter portion of the hybrid system under recall shortly after, the episodes of loss of power impairing vehicle operation have increased in frequency. An additional software update by Honda completed on 11/10/11 has further exacerbated the rate of transient failures of the ima system and impacted vehicle driveability. Multiple software updates pertaining the the ima hybrid system have also been installed on the vehicle by Honda dealer technicians over the previous 3 years.

After my 2006 Honda Civic hybrid received an integrated motor assist (ima) software upgrade in 2010, if the car is parked for one day (such as a Sunday, if I do not drive the car) the ima battery will drain within one half mile of leaving my home the next day, on a level roadway, even if the ventilation system and radio are off to reduce electrical load. Fuel economy also dropped about 10 mpg after the software upgrade. Without ima, the car has slow freeway acceleration, especially when traveling uphill. The Honda dealer says they cannot do anything because the ima system light does not illuminate (obd does not show a fault) although the dealer can reproduce the problem after keeping the car overnight. How do you know the ima software upgrade does not prevent the ima light from illuminating when there is an ima battery fault, therefore not requiring Honda to replace the ima batteries under warranty?
