Failure Date: 06/24/2014

Due to poor performance after a recent Honda ima hybrid battery software update, the electronic battery had turned itself off in order to extend its life. When the battery turned off, the primary electronic brakes were also turned off. When an accident happened on the opposing direction of traffic, it sent debris across the freeway barrier into my lane. I attempted to decrease my speed in order to maneuver around the debris, but I did not have sufficient braking power. If the brakes were not disabled in order to extend the battery life and decrease Honda of America's financial responsibility to replace batteries under warranty, I would not have ran over the debris that almost sent me straight into the median wall. I had seen the accident with plenty of time to slow down and I would have made it safely around the debris if I had proper working brakes. The brakes remain intermittent sometimes working as they should, other times not at all as stated above.

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?.

The contact owns a 2006 Honda Civic Hybrid. The contact stated that while driving approximately 30 mph, the integrated motor assist light illuminated on the instrument panel. The vehicle was taken to an authorized dealer where the contact was informed that the hybrid battery was deteriorating. A new software system was installed in order to save the battery. The failure continued and the contact also stated that the vehicle did not always accelerate once the accelerator pedal was depressed. The failure mileage was 76,000.

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.

The contact owns a 2006 Honda Civic Hybrid. While driving at an unknown rate of speed, the low beam head lamps shorted and the vehicle stalled without warning. The contact was able to coast the vehicle into a parking lot. The vehicle stalled again and was unable to be restarted. The contact was unable to determine if the VIN was included in NHTSA campaign number: 11v106000 (electrical system). The vehicle was towed to an authorized dealer who replaced the DC/DC converter, but the failure recurred. The ima warning light and the service engine warning light illuminated. The vehicle restarted with hesitation and stalled again. The vehicle was towed to the dealer who replaced the ima battery module and updated the pcm with new software. The vehicle was repaired. The manufacturer was notified of the failure several times and provided no remedy. The approximate failure mileage was 58,028.

Failure Date: 12/23/2010

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.

Failure Date: 12/22/2010

The contact owns a 2006 Honda Civic Hybrid. The contact noticed that the battery was rapidly discharging and failed to charge fully, causing the gas motor to run longer. The dealer was notified who advised the contact to have a software upgrade performed. The contact did not inform the manufacturer of the failure nor was the vehicle was repaired. The current mileage was 77,300 and the failure mileage was approximately 77,000. Updated 02/10/11the consumer stated he did inform the manufacturer of the failure and a warranty claim was made to the dealer and the manufacturer. The vehicle was given the Honda software upgrade by the local dealer. Since the software upgrade, the mpg continues in the 30 mpg range, down from the pre-failure mpg of 42 mpg. Current, post-upgrade is measured over the last 200 miles by the vehicles the on-board mpg device. The battery continues to discharge rapidly, the rpm idle increases from about 750 to 1500. The vehicle uses the starter motor instead of the ima battery. Updated 04/21/11.

Failure Date: 12/16/2010

Battery began performing what is know as a calibration where all motor assist ceases and the battery recharges. Once in a while this is okay however it gradually got more and more frequent to the point it became a daily routine or even occurred multiple times within the day. One cold morning the ima (battery light) came on. After taking the car into Honda, they performed 6 software updates. Since that time calibrations have increased in frequency. The battery will now calibrate after sitting for as little as 1 hour and will often calibrate several times within a single commute. At one point over the course of the day, about 80 miles, there were 5 calibrations. A few days later the car performed 4 calibrations in a 20 mile stretch. The ima light has not came back on at this point but I did take the car to Honda. They were unable to reproduce the condition. At this time nothing has become of the calibrations. While they have been merely annoying I am concerned that they pose a high safety risk as should the calibration come at the beginning or in the middle of a heavy acceleration, the car will loose significant power and can potentially cause a hazardous situation that could easily result in a collision. (when the battery calibrates, getting the car to accelerate is like pushing a freight train).

Honda hybrid recall (summer 2010) to update software to address battery problems has resulted in major degradation in what little power existed in getting up hills. Car 'freezes' and struggles to get up hills. Extremely dangerous driving in street of san francisco. Recently struggled to go up a highway onramp at 25-30mph - no load in car other than me. Not until 15+seconds on the flats could I slowly manage to get to highway speeds. In the few months since the notice, there are many accounts on the web of other owners experiencing same power problems. I know I bought a car with hardly any power but this is dangerous. Honda technician drove it with me and saw the problem. Attempted to diagnose and I got a call back that this is 'normal' as a result of the software recall update.

Failure Date: 10/01/2010

I have a 2006 Honda Civic Hybrid. The car no longer is getting assist from the battery. . Which causes it to not be able to accelerate when needed. Further, it sometimes surges, without notice when I am putting my foot on the gas. I got the 'fix' that we were informed was a software update that would prolong battery life. Instead it got rid of the electric assist, making it unsafe.

Failure Date: 09/23/2010

Honda's software reflash of the ima system in 2010 has caused my car to operate erratically. The hybrid battery is often completely unavailable to assist the regular motor when needed to accelerate to merge into high speed traffic, to pass other vehicles, or to avoid collisions. Additionally, when taking off from a stop the car sometimes hesitates to start moving, stutters, jerks or lurches. I have not been able to achieve more than 29 mpg since the software update, approximately 10 mpg less than I was getting before the update. California small claims court awarded me $9,867. .

I have a 2006 Honda Civic Hybrid. I brought it in for a software update to the ima system and since then, the gas mileage and performance is down a good bit. The acceleration is the dangerous thing - sometimes the acceleration is quite sluggish and this is due to this software upgrade designed to make the battery pack last longer so they don't have to replace it.

Failure Date: 08/19/2010

1. Honda Civic Hybrid battery loses power, does not perform idle stops that recharge integrated motor assist battery, inability to accelerate on freeway onramps or when driving circumstances necessitate acceleration, decreased gas mileage. 2. At 34,347 miles began noticing ima battery doesn't last long and makes acceleration difficult. At 62, 430 miles I am concerned for myself and my family's safety. Car extremely difficult to accelerate even on streets. At 69,388 problems continue with a noticeable dip in gas mileage. At 90,747 miles ima battery sensor indicates a problem. Battery not working properly. 3. Per Honda at each service only software was updated. No parts replaced. Therefore, battery is still only charges up to halfway. The battery isn't consistently dead to start with but it does die down again with driving.

I received a notice from Honda that my 2006 Honda Civic Hybrid needed a software update to stop premature battery failure. Had update performed. The vehicle is no longer a hybrid car. This car is dangerous to drive in nyc traffic as it now has no battery assist when the battery is at a 50% charge.

Failure Date: 08/15/2010

In response to a recall notice, I took my 2006 Honda Civic Hybrid in to 'update the software to extend the life of the battery. ' unfortunately, my car no longer drives like a hybrid: the motor does not stop, even if I am stopped for several minutes, whereas, before, it stopped every time the car did. The battery does not assist nearly as often, and the gas mileage has decreased significantly. I called the dealer, freeway Honda in tustin, and requested that they reinstall the old software, but they refused. I purchased the car largely because of the excellent mileage: I would never have chosen to basically turn it into a regular, non-hybrid, civic, which is what the software did. The Honda case # is [xxx]. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Honda Civic Hybrid--2006. Ima assist abnormalities following most recent Honda repair campaign. My 2006 Civic Hybrid was given a software update by Honda on 8/5/2010 following a campaign initiated by Honda to address loss of power and performance due to ima hybrid battery deterioration and failure. Prior to the update the vehicle would often lose battery charge suddenly, resulting in a significant loss of power and at one point stranding me in an intersection while turning left in front of oncoming traffic in July, 2010. The most recent update (I have had several from Honda in over the 4. 25 yrs of ownership) has not fixed the issue of sudden loss of power from transient battery failures that occur without warning, often when accelerating up steep inclines or attempting to merge into traffic. In addition to the ongoing issues, the hybrid battery now fails to provide adequate assistance when accelerating, merging into high-speed traffic, etc. And experiences wide fluctuations in charge, jumping from 1/3 charge to completely full with sudden drops of a similar fashion. These fluctuations continue to occur regardless of driving conditions, ambient temperature, accessory or a/c use or other extenuating factors and occur multiple times per week, and multiple times per day on occasion (6 battery failures in the last week alone since the update). I have experienced at least 1 near-miss accident in the last 30 days due to sudden loss of power and Honda's multiple attempts to address the failures from a software perspective have been unsuccessful.

Failure Date: 08/11/2010

I received a notice from Honda that my 2006 Honda Civic Hybrid needed a software update to stop premature battery failure. Had update performed. The vehicle is no longer a hybrid car. It basically runs off the engine. The only time the integrate motor assist unit works is when the car is first moving from a stop, and even then it is relatively useless. The vehicle previously was excellent. Motor assist worked great. Honda issued recall update to reduce the number of claims for early battery failure. They have shut off the hybrid system in order to stop battery failure which would have cost them over $2000 per car to replace. They have not extended the warranties of existing owners like myself who have 60,000 miles. The battery will now last to the end of the warranty period because it no longer needs to work. According to the dashboard, the car is constantly charging the battery, even when I push the pedal to get onto a highway. This is not the hybrid car I purchased and used for the past 4 years. It is basically a gas engine with 40 hp. The car hit over 6500 rpm to get up a hill with one passenger, and the motor assist didn't turn on. . But the power bars stayed at the middle range and Honda says it should. How does a vehicle reduce ima assist when hitting the gas? what is all this reserve battery for? probably to keep the flashing lights working when someone hits me in the back thinking I am actually moving. This update is not safe.

My Honda hybrid 2006 looses all its indicators when the weather is either hot or cold; I loose air conditioning, and speed indicator; ima system and check engine alarms goes off. Checked several times by Honda dealer; could not figure out the problem. This has been going on for about one year. After recent recall and software update installed yesterday, the car could barely start at a light (rpm up to 6000, drive engaged, barely any move forward), and not even an alarm light on anymore; this represents a major safety issue.

Failure Date: 08/04/2010

In response to August, 2010 recall notice from Honda for 2006 Civic Hybrid, I had the integrated motor assist (ima) software updated at the dealership on 8/4/2010. Since then, the software has been executing the ima battery recalibration routine with increasing frequency, to the point now where the recalibration is occurring 1-2 times per day at unpredictable times during my commute to and from work. During the recalibration period of about 5-7 minutes, the ima is not available to assist acceleration. The acceleration is suddenly sluggish when recalibration begins, and does not resume its normal characteristic until the recalibration finishes. The car is severely underpowered and can be dangerous when the expected acceleration for entering a freeway or making a turn across traffic, does not occur. Honda does not define this behavior as a failure, so no corrective action taken.

Honda has performed a software update on my 2006 Civic Hybrid. The results are tantamount to having replaced my car with another that has markedly inferior response, performance, and gas mileage:* about 10 mpg decrease since the 8/4/2010 ima software update* rare iva assist on starting from 0, resulting in a noticeable lag between depressing the gas pedal and movement from a stopped position - this is a safety issue. * responsiveness of acceleration at highway speeds inconsistent and unpredictable - since this affects driver reaction and responsiveness this is a safety issuenote: the software update renders the electric motor practically moot. Since in my case the battery drops its charge radically over a 24 hour period if not used, the update appears to be doing little more than preventing an already compromised battery from failing.

Failure Date: 08/01/2010

2006 Honda Civic Hybrid, battery software update. I took car to dealer for this update and it was installed. After the update I've seen an erratic change in the battery assist and this is a driving safety hazard. The battery assist disappears and there is no acceleration. I've taken the car back to the dealer twice after the software update and they insist their computer says all is ok. This vehicle was sold as a hybrid and there was a income tax credit but this software update just about makes it a non hybrid in addition to the safety hazard by losing the battery assist thereby losing acceleration. For instance waiting for a break in traffic to make a left turn, if what they call the ima battery assist is not working then you don't get the acceleration you expect and leave you vulnerable to being in an accident while making the turn.

Failure Date: 07/29/2010

I own a 2006 Honda Civic Hybrid. Approximately two weeks ago I had a software update on the ima system and since that time the acceleration of my car has dramatically (and perhaps dangerously) decreased. Honda claims it was done in order to preserve the life of the battery however at no time did they say it would adversely affect the performance of the car. The gas mileage has also suffered badly. Prior to the software update the car was running fine and I was getting excellent mileage.

Failure Date: 07/20/2010

The contact owns a 2006 Honda Civic Hybrid. The contact stated that she received notification of an unknown manufacturers recall pertaining to an engine software upgrade. The recall repair was performed by an authorized dealer however following repairs, the hybrid battery became non-functional and would not hold a charge. The vehicle began to exhibit poor gas mileage and the vehicle would sluggishly accelerate. The manufacturer advised that they were in the process of designing an additional software upgrade. The vehicle was not further repaired. The failure mileage was approximately 80,000 and the current mileage was approximately 82,000.

Failure Date: 07/15/2010

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.

Failure Date: 07/15/2010

Several times in the past the acceleration in my 2006 Honda Civic Hybrid has failed to provide the extra burst of speed when needed, making me uncomfortable in traffic. When this situation happens as I am leaving my subdivision I feel helpless in a situation of which I have little control. When I need to make turn from my subdivision from a stop, I need to rapidly accelerate to 45 mph uphill. Much of the time there is traffic approaching from the left which I am unable see to until they are on the crest of that hill, approx. 150' away. As you can see, I depend on the hybrid system working properly for that extra burst of speed. When this happens I notice the ima battery charge indicator showing the battery is in a depleted state. I do not know why this occurs so rapidly when 99% of the time it is just fine. I was relieved that Honda motor CO. Was proactive in notifying me of a software patch to enhance the performance of the ima system of which I had immediately installed. What my wife and I have noticed since the software patch was installed is the engine revs up higher during acceleration then there is a momentary hesitation before the ima system assisted the engine to get up to speed. Also since the patch was installed, the ima battery level indicator is at or near full charge. I have noticed an apparent decrease in fuel efficiency, but I am still compiling data to make an exact determination of the extent of that problem.
