Battery Dead Problems of Honda Civic Hybrid

The contact owns a 2007 Honda Civic Hybrid. The contact stated that "integrated motor assist system compromise" displayed on the instrument panel. The vehicle was taken to Honda motorwerks (500 4th st s, la crosse, WI 54601, (888) 434-6632) where it was diagnosed with an internal battery failure that needed replacement. The battery was not replaced due to cost, but the contact was advised that the vehicle was still able to operate using the hybrid system or fuel. The contact stated that using the hybrid system was fine during the summer, but during the winter months, due to colder temperatures and shorter daylight hours, the vehicle would lose power without warning. The contact stated that it was a known issue that the internal battery degrades over time and failed to keep a longer charge. The manufacturer was made aware of the failure and provided case number: 06581479. The failure mileage was approximately 125,000.

The car is a hybrid, in which heavily relies on a battery. However, the battery unit is not so great and dies every few years. If one day the battery dies when I'm driving, it can be extremely hard to steer as it also powers the steering wheel. This can cause a incident in the road or at an intersection. Moreover it is too expensive to be buying a new battery every few years, so people remove the error code and sell the car, which causes this to become an never ending chain.

The ima battery has failed. The ima battery was given a computer "patch" last year to help the ima perform better than it had. The performance after a stop was very poor and the pick up lagging seriously behind the engine. The "patch" did not work, it made matters worse. I am now faced with the large expense of having to replace this battery. Beyond the expense is the safety issue of not having the power to accelerate because the "patch" adjusted the ima system poorly . .

It appears that there may be a trend of premature ima battery failures for this vehicle and should be investigated. On our brand new 2010 Honda Civic Hybrid with less than 952 miles and less than 4 months of use, the ima and check engine lights came on. Ima battery - premature battery module deterioration (code p0a7f. ) was determined to be the cause of ima and check engine light. The battery module was replaced by the Honda dealer. Ima and check engine light came again in October 2013, less than 3 year of use. Took it to the Honda dealer. They checked it out and replace the battery module on 10/31/2013. The ima code was the same, p0a7f high voltage battery deterioration. The mileage was 46,084. Two ima battery failure in less than three years appears to be excessive. The original warranty on ima battery module is 8 years, 80,000 miles (for ohio) as listed in the owner's manual . For some states, it is 15 years, 150,000 miles. Although, both batteries were replaced under original warranty, it appears that there may be a trend of premature battery failures for this vehicle and should be investigated by appropriate agencies and the car company. Safety as a result of loss of power without the battery assist, fuel consumption (mpg), replacement costs of batteries and time required for the repair/replacement are the main concerns. The warranty info on the replacement is sketchy and unwritten.

The car has a propensity to lurch forward at low speeds. When making a turn or stopping at a light the engine intermittently will rev and thrust the vehicle forward. If the driver is not knowledgeable or prepared for this tendency, the vehicle can thrust forward and strike whatever is in its path. The second problem that I have encountered is that the vehicle uses a malfunctioning integrated motor assist (ima) feature that is supposed to give the vehicle extra power to enter a highway and safely merge with oncoming traffic. Unfortunately, this feature is unreliable and can leave the vehicle and driver in a position of not having enough power to safely merge with high speed traffic. This differential in speed is very unsafe. In 2011 I had the li battery for my hybrid vehicle replaced. This battery failed in less than a year. I was told by the senior mechanic at the Honda dealership that Honda corporation was aware of this defect. And that Honda knowingly replaced the li batteries last year with known defective batteries as a quick fix to appease customers. There is something seriously wrong with this technology, and I believe that Honda is intentionally not disclosing the true nature of the problem with these hybrid vehicles. I would be interested in knowing if the Honda Civic Hybrids are experiencing a higher than normal accident rate due to engine surging at low speeds and inability to safely merge with highway traffic because of loss of power due to the ima system.

I own a 2004 Honda Civic Hybrid, with a defective ima (hybrid) battery. I had noticed difficulty accelerating effectively onto freeway ramps and just sluggish performance in general. Honda diagnostics state the battery has failed. The car only had 85k miles on it at that time. The poor performance of the vehicle makes it frightening to get on and off the freeway where I live. Replacement cost is $3500, which I cannot afford. Many websites such as hybridcars. Com and edmonds. Com have 100's of posts by frustrated consumers. Unofficial estimates of later model vehicles, with even lower miles, state at least 5% of the cars have defective battery life. Honda could extend the warranty or lower cost for replacement but is stallingas there are class action suits in the process of being filed. Please, please, help Honda Civic Hybrid consumers, many of whom were counting on Honda's good name and hybrid fuel economy precisely because they could not afford to spend $$ repairing a car or guzzling gas. I am a medical student, and single mother who was counting on this car making it another 5 years. I have cared for it well and cannot afford this expensive repair.

2008 Honda Civic Hybrid,(problem), ima battery discharge, while driving the battery will discharge to 0 or 1 bar and motor assist will not work until battery charges up, which can take awhile, with no assist the car is slow and dangerous. Also with low or no battery power the gas mileage drops about 20%. The reason you buy a hybrid. After research on the web this seems to be a large problem many other have it appears that Honda doesn't have a fix for this problem. The dealer will reprogram your ima system which doesn't allow for as much battery backup,which also decreases gas mileage. This gives the mpg of many other cheaper non hybrid cars. If after many battery discharges and if the diagnostic computer shows that the battery is bad then a new battery can be installed, the problem still is there, the reprogrammed ima system still doesn't allow for full battery backup and the mpg will not increase to new care status. Again, not what you paid for in the first place. I think Honda needs to address this problem. Many hybrid owners simply want what they bought in the first place. I think with your help,maybe Honda will step up to the plate and address this problem and not try to cover up or prolong the battery with updates to the ima system which appears not to help, this seems to prolong battery life, but doesn't allow for the full benefit of the hybrid concept.

The vehicles battery has failed and the car does not have enough power to safely pull into intersections or incoming traffic. There have been several near misses due to this issue. We are terrified when driving the vehicle.

I have owned a 2009 Honda Civic Hybrid since 12/8/08 and have had numerous problems with the battery and the hybrid system. On October 5, 2009, as I was entering an on-ramp in arlington, va, the ima system completely failed and the regular internal combustible engine (ice) revved to over 4500 rpm to provide power on the on-ramp due to there being no ima assistance. Without the hybrid power assist, I was nearly hit by other traffic. At that time, the ima warning light and check engine light illuminated. I brought the vehicle to ourisman and they spent several days getting a new ima battery system ordered and installed, claiming there was a bad cell in the 10-month old ima battery. In Nov and Dec 09, I discovered the car battery dead twice in the garage. On the night of February 13, 2010, the electrical system (battery and hybrid drive) failed on a busy street off of military rd, NW. The car was backing out of a driveway into the road when it completely died. As there was no power for hazard lights, I personally directed traffic around the dead car until I could get a jump. After a battery jump, I tried to charge the battery for a time, but when I put the car into reverse, the car died again and I had to get a second jump. 15 minutes later, I disconnected the cables and drove to ourisman Honda in bethesda, MD. On the way, the vehicle almost died twice but I was able to get the car to ourisman Honda. They replaced the battery, but a week later on February 23, 2010, the car died again and I was barely able to get it to ourisman Honda for service again. After several days, they identified the problem as being with the relay near the hybrid system. The car still acts strangely and they hybrid assist does not work as well as it used to. Acceleration is not normal, the hybrid assist does not come on at normal times, and there are incidents of acceleration and engine revving when I release the gas to brake before a stop sign.

This car fails to start. Had been reported to dealer and was told every thing was ok. On 27 Aug 2005 this cars engine stopped while driving down hill. When it was towed to dealer . I was told the main battery was dead.

The transmission seemed to slip, the engine rpm's would go up but speed would not change. As you drove down the road you could see the tach which shows rpm go up & down, up & down all the time but the speed would stay the same. Very poor gas mileage around the mid 30's not even close to the 50 mpg that we were told. Then one day the car just made a bang and stopped, the transmission steel belt inside broke into many pieces and the car wouldn't move. $1800. 00 to fix this then we still had the rpm up & down problem. Then @ 80,000 miles the battery light came on had update done to computer, made the mpg even lower and we were told the hybrid battery is going bad, replacement cost $3000. 00. Couldn't afford this then the hybrid battery died 100% couldn't drive car without any kind of charge in battery and it also cause another part of the hybrid system to go bad which cost $1700. 00 to fix. So we needed a new battery @ $3000. 00 and another hybrid component for $1700. 00 so we could drive this car. It had under 100,000 miles and Honda wouldn't help pay a dime, and all this not to long after we spent $1800. 00 to have transmission belt fixed. So we traded in the car to Honda for a Ford. We also spent $1200. 00 to have the ac compressor replaced on this car so it was a lemon from the start and all this time Honda wouldn't help at all even though we had complained time and time again. Now they are in a class action law suit which I hope they are made to pay millions. I would never purchase another Honda hybrid, this car was to save us money on gas because of the mpg but it cost us thousands in repairs that by far cost us more than the money we saved in gasoline.
