The vehicle will shut off in traffic without any warning from the cars system. Unknown if there is any interference being caused by internal or external.

The A/C relay switch has been replaced several times and now I'm having to replace the actual ac switch on the compressor due to it bogging my engine down every time I turn it on and it still won't blow cold air. This has been a continued issue and I've seen a lot of post online about it. So why hasn't it been recalled or something done about it.

- Dobson, NC, USA

My 2009 Civic has a problem that has affected many other eighth generation Civics: The A/C relay is faulty and is of a poor design and/or manufacture. The A/C relay is known to fail very prematurely and cause the compressor for the air conditioner to spin/cycle continuously or stay on (even when the A/C is not turned on), and thus cause the compressor to heat up tremendously and fail, which causes mechanical damage inside the cooling system. There are countless stories online, in car forums, and at Honda dealerships and repair shops to back this assertion. Not only does this substandard A/C relay cause expensive damage that is not easily repaired (how does a 4 hour tear-down and reassembly sound?), but it represents a potential safety hazard since the relay is faulty and may cause issues not only with the rest of the electrical system (including the fuse box where it is located) but also because of the tremendous heat that a faulty relay generates when it causes the compressor to continuously cycle. The metal of the compressor actually changed color when it continuously cycled on my car, and is a telltale sign of this ever common failure. Honda is aware of this issue but has not seen fit to address it though tsbs/recalls for other models have been issued.

The contact owns a 2009 Honda Civic. While driving, the vehicle suddenly shut off. The vehicle was taken to an independent mechanic who replaced the ignition switch, but the failure continued. The mechanic also diagnosed that the engine block was cracked and was leaking coolant. The vehicle was not repaired. The local dealer (Honda super store of lisle, illionis) and the manufacturer were notified of the failures. The failure mileage was 109,000. Updated 10/26/17 the consumer stated several cylinders were damaged as a result of the engine crack.

TPMS indicator is always on. Have taken to dealer to get service but they have said it's an electrical glitch cannot be fixed. This presents a safety issue if a real problem occurs not knowing when tires need adjustment.

The center (interior) brake light works intermittently. Many others have had same problem. Only affects ex model led light assembly. It is unsafe and costly fix. It should be recalled.

I was hit on the passenger side of the car by an SUV. The repairs were with genuine Honda parts but ever since then the front controls where the radio is has been extremely hot. Almost to the point I think I burn my hands to change the radio station. I think it may be hot enough to start a fire with melting the controls in the back. I have been told there is nothing that can be done or it will cost me a lot of money to diagnose it. I just see it as a safety issue to have the dash so hot it burns people. The passenger airbag did not deploy in the crash and possibly should have.

The integrated motor assist (ima) system in my 2009 Honda Civic hybrid erratically charges and discharges hybrid battery pack, causing serious drivability issues. The problem first developed at about 8000 miles when the original hybrid battery pack failed. Replacement of the hybrid battery pack and numerous attempts to re-program the ima control software have not corrected the problem. It has continued and worsened through the present mileage of about18000. Acceleration continues to be hesitant, jerky, and extremely weak without the hybrid system operating correctly. The car is dangerous to drive on the interstate because the ima system may be charging a low hybrid battery even when acceleration is needed. In those circumstances there is no power available to accelerate the car. This is opposite of the way the ima should work. In addition, gas mileage has dropped from an average of 43 mpg when the car was new to an average of 34 mpg. The vehicle has been into a Honda dealership 7 times over 20 months for work on this problem. The Honda service technicians have described the car as scary to drive and stated I've never seen one do that before?. american Honda claims the car is operating as designed and will authorize no further work. With its poor service history, Honda dealers are not interested in taking the car in on trade, leading to a substantial loss of value.

I own a 2009 Honda Civic hybrid. I've had issues with low power and halting acceleration due to low battery conditions accompanied with the dash engine light coming on. Honda dealership has applied software updates to my vehicle to address this twice, but those simply trade mileage for battery life, degrading the value of a hybrid. I believe that the ima battery has known problems and that Honda is not addressing the issue. I'm afraid to merge onto highways with a low battery due to the lack of power and acceleration.

My 2009 Honda Civic LX is having a hard time starting.

- Rolla, MO, USA

Honda is calling in hch owners for a software update to "preserve the battery." The result of this software update essentially shuts the ima battery down frequently, leaving the car to run on just the motor which was intended to run with the ima. Aside from the "switch and bate" issues (mileage dropped below a standard Civic), the safety issue involved is a frequent lack of acceleration capability, especially on an incline or merging into traffic.

TL * the contact owns a 2009 Honda Civic hybrid. The contact stated that the electronic motor assist warning light illuminated. The vehicle was taken to the dealer where the battery was replaced and the software was updated. The contact noticed after repairs that the vehicle would drive sluggish and there was limited acceleration power. He stated that the electronic motor assist did not assist with the acceleration of the vehicle as intended. The vehicle was not repaired. The current and failure mileage was 11,962. Updated 12/08/10

While braking, the car starts to regenerate (charge the hybrid battery) and then a short burst of assist (electrical drive from the hybrid battery) while my foot is on the brake. This happens about twice a week and is extremely dangerous since I sometimes get into stop-and-go traffic. This means that I could be braking and the car will accelerate, possibly hitting the car in front of mine.

I currently am the lessee of a 2009 Honda Civic hybrid starting this January, the hybrid battery charge level goes from almost full (8-10 out of 10 bars) to virtually zero (1 bar) every other week (the technical term for this is a "recall" or recalibrating). This summer, it started happening every 3-4 days, and whenever I had the A/C on. Then, it started to happen every 100 miles (which made it very predictable). The problem is that when in the 'recall' state, the car is almost unresponsive and does not accelerate much, if at all. This poses a safety hazard especially when making left turns when the oncoming traffic has a blind spot, or is coming around a corner. It also impacts fuel efficiency substantially. I have seen about a 7 mile-per-gallon drop in fuel economy. I took the car to the dealer who told me that there were no codes in the system but there were 3 software updates, so they installed those and that if I still had the problem, to come back. I still have the problem so I schedule the appointment and I take the mechanic for a test drive and he sees the charge drop rapidly and states that it's completely normal. I argue that is happens too often and he still says "it's fine." About 3 weeks later the ima light and 'check engine' light come on. Turns out, it was a blown fuse (for the A/C electric drive, fuse #22) so they replace it, and tell me that they checked the current draw on the A/C just to be safe and claimed everything was fine. Now, about 2 weeks later, every time I start the car it does a recall. This is beyond annoying and now I'm starting to see drops of about 10 mpg because of this problem, as opposed to the previous 6 or 7. I'm thinking that Honda knows that their nimh battery cells are prone to premature failure and will not do anything to fix the issue.

1. the car would not turn over when you turn the key after the car had been driving for a while. 2. came out one morning and car would not turn over called aaa and dealer, checked the battery green light was bright got car to start and went to dealer, 3. they said starter was bad and replaced with a new one under warranty. About 3 to 4 weeks later problem came back and was able to start car and took to dealer again and this time they could not find any problem they just noted it and awaiting for the issue to happen again.

2009 Honda Civic hybrid. Consumer requests immediate replacement of a defective battery pack. The consumer stated the (ima) integrated motor assist light illuminated. The diagnosis indicated a battery condition monitor module intermittent malfunction. The light illuminated again two months later. Although, each visit resulted in electrical repairs with specific code reviews, recalibrations, clearance and resetting, the underlying condition still has not been resolved.

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.
