Honda Civic Natural Gas 2012 — Problemas relatados

Dear NHTSA Vehicle Safety Complaint Team, I am submitting this complaint regarding a recurring and unresolved hybrid-system issue with my 2012 Honda Civic Hybrid. Vehicle Information Make/Model: 2012 Honda Civic Hybrid VIN: [XXX] Current Mileage: Approximately 144,000 miles Diagnostic Trouble Code: P1440 Reported Symptoms: IMA warning light illuminated, battery/charging warning light illuminated, and vehicle starting problems. Description of the Problem My vehicle has developed a serious issue involving its Integrated Motor Assist (IMA) hybrid system. The IMA warning light is illuminated, and the vehicle has stored diagnostic trouble code P1440. The battery/charging warning light is also illuminated. I have experienced a no-start condition in which the dashboard lights illuminate, but the vehicle does not start. Attempting to jump-start the vehicle did not resolve the problem, and the vehicle also would not start when shifted into Neutral. I have contacted multiple Honda dealerships to investigate this problem. However, I have been informed that my vehicle does not qualify for Honda Service Bulletin A20-030, despite the P1440 trouble code and symptoms that appear consistent with the reported issue. This has left me without a clear resolution to the problem and concerned about the reliability and safety of the vehicle. I am particularly concerned about the potential consequences of a hybrid-system or electrical-system failure that could leave the vehicle unable to start or operate unexpectedly. Request for NHTSA Review I respectfully request that NHTSA: Review whether this condition is associated with a broader defect affecting the IMA system or related hybrid components in 2012 Honda Civic Hybrid vehicles. Investigate whether the reported symptoms and P1440 diagnostic trouble code may be associated with the defect addressed by Honda Service Bulletin A20-030. Review Honda's eligibility criteria for the service bulletin and determine whether add INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Failed braking after repairing 9/14/26, Sun Auto did not bleed my brakes after installing front pads and rear shoes. When I brought this to the Service writer's attention on 9/18/26 his response was that I did not purchase the brake fluid service. Yes an independent Brake shop inspected and resolved the issue.

We were not injured. We fixed the problem before we did get hurt..message came up.. “Check airbag system”. We had t replace our driver’s side airbag at the cost of over $1,500.

The contact owns a 2012 Honda Civic. The contact stated that the front passenger’s side seat weight sensor failed to operate properly. The contact stated that while the front passenger’s seat was occupied, the air bag enabled warning light was flashing off and on. The contact associated the failure with NHTSA Campaign Number: 26V332000 (Air Bags). The dealer was contacted; however, the contact was informed that the failure was not associated with the recall. The manufacturer was not made aware of the failure. The failure mileage was unknown.

The contact owns a 2012 Honda Civic. The contact stated that the alarm indicator sounded off intermittently without cause. The vehicle was taken to a certified mechanic, who informed the contact that the alarm was a factory-made system and then suggested pressing the key fob twice to stop the alarm from sounding off. The vehicle was not officially diagnosed or repaired. The manufacturer was not informed of the failure. The failure mileage was 167,842.

I purchased a vehicle from a private seller on offer up. The seller stated the vehicle was clean title, he also stated the vehicle was low mileage with 112,000. When I got the vehicle the tire sensor was showing on the dash and the air bag sensor. After purchasing the vehicle I later found out the vehicle was salvage, and the mileage is also roughly 180,000 miles or more.

My passenger airbag light is on and stays on.

The contact owns a 2012 Honda Civic. The contact stated that while driving at various speeds, the vehicle hesitated or stalled while depressing the accelerator pedal. The “Check Emission Systems" message was displayed on the instrument panel. The contact then received notification from the Manufacturer for Honda Service Bulletin: 19-106. The vehicle was taken to the dealer, where a PCM update was performed. Recently, the contact stated that the "Check Emission Systems" message returned, and the vehicle hesitated while depressing the accelerator pedal. The dealer was notified of the failure and provided the cost for a diagnostic test. The manufacturer was notified of the failure, and the contact was provided with a case number. The contact was also informed that dealers were independently owned and could not be forced to repair the vehicle under the service bulletin. The vehicle was not repaired. The failure mileage was approximately 211,000.

Component or system failure: The vehicle experienced failures involving the engine/ignition system, emissions system, Vehicle Stability Assist (VSA), and power steering. On July 14, 2025, warning messages appeared for “Check Emissions System,” “Check VSA System,” and “Check Power Steering System.” Diagnostics identified engine misfire code P0304 (Cylinder #4). On August 11, 2025, an authorized Honda dealership confirmed a seized spark plug and cylinder head damage, indicating an internal engine defect. The vehicle is currently with the selling dealership and available for inspection. Safety risk: Simultaneous failure warnings for emissions, VSA, and power steering created an unsafe driving condition. Impaired stability control and power steering increase the risk of loss of vehicle control during turning or emergency maneuvers. Confirmation of problem: Yes. Independent diagnostics confirmed the misfire. The selling dealer attempted repairs between July 22–25, 2025, but the same warnings returned. On August 8, 2025, the dealer admitted it lacked tools and software to diagnose or repair CNG vehicles. Honda later confirmed internal engine damage. Inspections: The vehicle was inspected by the selling dealer and an authorized Honda dealership. A third-party warranty administrator authorized a tear-down inspection. The vehicle has not yet been inspected by Honda Motor Co. or NHTSA. Prior warnings and recall concern: Warnings first appeared on July 14, 2025, about two weeks after purchase, and recurred despite repairs. The 2012 Honda Civic CNG has multiple recalls involving engine, fuel, and emissions systems, and these failures are consistent with known defect patterns, warranting further investigation.

The contact owns a 2012 Honda Civic. The contact stated that while driving at an undisclosed speed, there was an abnormally strong fuel odor detected. The contact pulled over and parked the vehicle, and became aware that there was fuel leaking onto the ground. The vehicle was taken to an independent mechanic, who determined that the fuel line needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 171,026.

I have had this 2012 for a little over a year, within the past 6 months periodically the check air bag system warning lamp comes on if I make a sharp turn or move the steering wheel very fast. On the guage it says that the passenger side air bag is off..This issue just came out of no where, but generally the car runs great

While driving, my 2012 Honda Civic Hybrid suddenly loses power and steering ability. The vehicle stalls and the steering wheel locks up, making it impossible to safely maneuver. This has happened multiple times, including in traffic, creating a serious risk of collision. When the failure occurs, warning lights illuminate on the dashboard, including the IMA light, anti-lock brake light, and others. In some cases, all dash lights flash before the car stalls. When scanned with an OBD tool, the vehicle shows power inverter-related fault codes. The symptoms are consistent with the IMA motor power inverter defect described in Honda Recall H98 (2012–2015 Civic Hybrid inverter recall). However, my VIN does not currently show as part of that recall. Despite this, the vehicle is clearly experiencing the same safety defect. This defect causes sudden loss of propulsion and steering assist, placing myself, passengers, and other drivers at serious risk. The vehicle is available for inspection upon request.

I am reporting a serious safety concern with my 2012 Honda Civic Hybrid. What component or system failed and is it available for inspection? The hybrid drive system and regenerative braking system are malfunctioning. The hybrid battery recharging system including the MPI have failed, causing the vehicle to operate solely on the gasoline engine. This results in degraded braking performance due to the loss of regenerative braking. How was safety put at risk? When the hybrid system fails, braking performance is noticeably reduced, increasing stopping distances. This creates a high risk of collision, especially in sudden-stop situations or heavy traffic. Additionally, the sudden loss of hybrid power assistance can cause unsafe changes in vehicle acceleration and handling. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. The issue has been confirmed by Pearson Honda in Midlothian, Virginia. They state the MPI needs to be replaced and state my VIN is outside their "factory warranty extension". Multiple calls to Honda America state that I am responsible for all repairs and that this is not their problem and will not clarify how they decide what VIN's are included in the extension. Has the vehicle or component been inspected by others? The vehicle has been inspected by Pearson Honda in Midlothian, VA and documentation is available. It has not been inspected by police or insurance representatives at this time. Warning lamps, messages, or other symptoms prior to failure? Yes. Warning lights for the hybrid system and/or IMA (Integrated Motor Assist) illuminate promptly as you start the vehicle. These first appeared last week ([XXX]) and have occurred multiple times since.

The contact owns a 2012 Honda Civic. The contact stated that while attempting to park the vehicle, the vehicle was turned off and the vehicle started to roll away. The vehicle was stopped, and the parking brake was engaged to stop the vehicle. The vehicle was towed to an independent mechanic, where it was diagnosed that the front axle had failed and needed to be replaced. The vehicle was repaired. The contact also stated that while at a stop light, the vehicle vibrated, and the contact heard an abnormal sound coming from the vehicle. The accelerator pedal was depressed, and the vehicle unexpectedly lunged forward. There was no warning light illuminated. An independent was contacted; however, the vehicle was not diagnosed or repaired. The dealer was contacted. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 156,000.

Odometer Fraud. The contact purchased a 2012 Honda Civic. The contact stated that before attempting to register the vehicle, it was discovered that there was a mileage discrepancy. The vehicle was a private dealer sale. At the time of purchase, the vehicle mileage was 116,000. Through a Carfax report, it was discovered that the mileage was 159,000.

So according to Honda Service Bulletin 20-030, all honda civic 2012-2015 hybrids having IMA Motor Power Inverter (MPI) have to fixed. I have the SAME CAR, SAME MODEL, SAME YEAR AND SAME ERROR CODES AS THE SERVICE BULLETIN AND THIS IS SUCH A SERIOUS ELECTRICAL POWER INVERTER ISSUE. Yet HONDA IS denying to work on it, even though there is 15 years or 150,000 miles warranty for this specific issue and MY CAR HAS 95000 miles. Yet HONDA is trying to run away from fixing it by claiming the VIN number is not associating whereby MY CAR IS EXACT SAME AS THE MODEL, year and issue for the GIVEN SERVICE BULLETIN. This is complete absurd and consumer rights are being thrown away by Honda. I am very sure that my United States NHTSA, state consumer protection, federal trade commission, all are going to help me and make Honda pay for this. I have attached the service bulletin and here my error codes on the car: P1437 Motor Drive Module (MDM) Short Circuit POA78 Tmu-L Motor Power Inverter Module Internal Circuit Malfunction P15A5 Motor Current Sensor Circuit Malfunction Clear Confirmed & Pending Trouble Codes 2 Pending Trouble Codes POA78 Tmu-L Motor Power Inverter Module Internal Circuit Malfunction P15A5 Motor Current Sensor Circuit Malfunction Clear Confirmed & Pending Trouble Codes ^ ^ 2 Permanent Trouble Codes POA78 P15A5 Motor Current Sensor Circuit Malfunction Tmu-L Motor Power Inverter Module Internal Circuit Malfunction

Paint defect. Paint faded and clouded on vehicle due to cheap paint used during manufacturing. I was never notified about the extended warranty. I contacted Honda and let them know, but was told the warranty ended. I financed my vehicle through American Honda for 5 years, and serviced my vehicle via Honda dealerships. Never did this come up as a possible repair that I could have fixed by them. I was told that Honda used a third party to contact owners.

Odometer Fraud. The contact purchased a 2012 Honda Civic. The contact stated that while attempting to register the vehicle, it was discovered that there was a mileage discrepancy. The vehicle was a private sale. At the time of purchase, the vehicle mileage was 119,560, and the contact stated she looked at the title and took the vehicle to a mechanic to verify and noticed that the mileage was 193,099.

It has happened more than once since 3 years ago. If I’m running my AC in the car, when I accelerate the car will skip/jump. It’s extremely expensive to repair and the problem isn’t even getting fixed. I basically can’t run my AC if it’s hot outside

Esp code1.33-06 while driving car I suddenly lose of power steering making it difficult to control vehicle

This is a serious matter that needs to be evaluated as it is a potentially fatal safety issue for human drivers of 2012 Honda Civic. This email needs to be sent please to the Department of Transportation and the National Transportation Safety Board for evaluation of extension of recall: meaning other 2012 Honda Civic vehicles that have the same type or similar area of issues as the two above stated recalls and from the same manufacturer as the 2012 Honda Civic vehicles but whose VIN were not included in the group of VIN numbers in the original recalls) a. 2019 - control arm bushings cracked - cause: leaking - front lower arm compliance bushings, both replaced by Honda( documention available upon request) b. 2019- right front tire shred and upon inspection by Goodyear no nail or issue could be found for the one right front tire shredding. (documentation and images available upon request) c. 2022- right front tire shreds while driving and upon inspection by Goodyear no nail or issue could be found for the right front tire behavior. (documentation and images available upon request) d. 2024-right front control arm mount and right control arm failure while driving causing the vehicle to be a total loss including from collateral damage. It happened at a low speed but if it happened at a higher speed it would have been potentially fatal. Corporate American Honda made aware and Corporate American Honda made aware this is to be reported to the Department of Transportation and Corporate American Honda response was that they were taking no action to the situation of the request for evaluation of extension of recall, besides just collecting the information I was reporting to them due per Corporate American Honda to it potentially costing Corporate Honda money and that they American Corporate Honda were willing to wait the couple of months that it could potentially take for the Department of Transportation to evaluate. Police report was taken, but I do not have a copy.

Odometer Fraud. The contact purchased a 2012 Honda Civic. The contact stated that while attempting to repair the vehicle, it was discovered that there was a mileage discrepancy. The vehicle was an independent dealer sale. At the time of purchase, the vehicle mileage was 71,00 and at the time of replacing the instrument panel, it was discovered that the mileage was 190,000.

ABS/VSA module faulty. Upon internet research it seems to be a very common problem among owners of this vehicle.

I was 3 hrs away from home and I started my vehicle and the air bag light began flashing and beeping. The light was on the message board that indicates my speed, clock, fuel, etc. it basically is the information center for the car. I pushed the information button on the steering wheel to clear it but it kept blinking and flashing the entire way home. I also turned off the engine and restarted it but no luck with that either. It was a very distracting experience having to drive 3 hours like this. I made an appointment with my mechanic and he diagnosed it as the Occupant Passenger Detection Sensor. This will cost $800.00 to repair. The car is not drive able in this condition because of the safety of the air bag. I looked up recalls but it seems my car has none.

When my car reaches speeds above 60mph the steering is difficult to control (a lot of Play in the steering wheel). I took my vehicle in to a Monrovia, CA Honda Dealer in May 2024 to fix the issue. The dealer replaced the bushings but did not fix the steering issue. This vehicle feels dangerous. I noticed on the internet there are a lot of mechanics talking about steering issues in the model years that my car is under. I am frustrated that the Honda dealers don’t seem to want to fix this issue. I’ve already paid a great deal of money in up keep and the problem has not been corrected. I have had no warning lamps or signs of leaks just a lot of play in the steering wheel and lack of control.I don’t feel safe on the highway in this vehicle.

Driving around town, I stopped our 2012 Honda Civic at a stoplight. The brake pedal vibrated from the ABS modulator, then went all the way to the floor. I had the brake system checked at a workshop, bled the brake lines, and the same situation repeated. It was recommended I replace the brake modulator and brake pump. I called our Honda dealer and the brake pump is on hard backorder with no indication of when or if it will be available. A check of junkyards showed very few of these pumps potentially available, indicating demand is very strong. Many of the Civics in the junkyards we saw were totalled due to front end collissions. Perhaps they discovered the brake issue too late? The car is not driveable. After reviewing forums and [XXX] there were many reports of brake problems with 2012 - 13 Honda Civics. I believe this warrants a close look. Brakes are the most important part of any motor vehicle in my opinion, and until there is a remedy my car will sit as a 3,000 lb paperweight.

The contact owns a 2012 Honda Civic. The contact stated that while driving at an undisclosed speed, the steering wheel seized. There was no warning light illuminated. The contact stated that the steering wheel became difficult to turn. The dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was not available.

Power Steering suddenly failed after I stopped for a stop sign. The EPS light was not on prior to stopping but came on after the steering failed. Managed to get to the nearest Honda Dealer and was told they wouldn't touch it. Managed to get to a local repair shop who looked up the issue and reset some code(s). They told me it could happen again at any time. This is an extremely dangerous problem that could cause serious damage or death if it occurred while driving. I can't understand why Honda hasn't figured out a solution and issued a recall.

ABS Control Module leads fell off. The 2012 Honda Civic has a sealed ABS/VSA control module. This module has leads connected with rigid solid core cables that are known to disconnect and fall off due to natural heat and vibration. This happened with my vehicle. The vehicle lost acceleration, power steering, dash lights, and power breaking on the highway. When I attempted to restart it all of my lights came on: charging system, VSA, ABS, Power Steering, and Power Breaking.

Car is stating air bag system check on and off.

The IMA inverter system keeps malfunctioning without any clear reasons, and the car is in drive mode, which makes the electric motor unresponsive. Additionally, the braking system also malfunctions, leading to a lack of control over the vehicle. I have tried to repair it multiple times, but to no avail. It keeps malfunctioning without any apparent reason.

Owns a 2012 HONDA Civic Hybrid. While driving ~30MPH, the IMA/braking/engine/charging/ABS lights illuminated. The car still driving but the hybrid system fails. Also, when starting the engine it switches to using the starter instead of the EV motor. The 12V battery will not charge and die soon, which increases the risk of a stall on the road, thus leading to a crash. The vehicle was taken to a Honda Dealer which suggests a Model Power Inverter failure. There is a Technical Service Bulletin: 20-030 (Warranty Extension: 2012-15 Civic Hybrid IMA Motor Power Inverter) related to the failing parts, however, the vehicle was not covered under the TSB. The vehicle was not prepared. The failure mileage was approximately 123,000 miles.

The power steering light will come on and the cars power steering no longer works. I was driving down the road approximately 60 mph and the power steering light came on and I could barely turn the steering wheel. I was able to stop and shut the care off and restart and the power steering worked again. On future drives the power steering intermittently will go out forcing me to stop and shut the car off and restart. I took vehicle to Honda dealer and the dealership and I was informed I needed to replace the EPS control unit, which I did. The vehicle was clear of any problems a a while but the same issue is now happening again. Went back to dealer and they reset code 51-04 and said they could not find any problem. Less than an hour after leaving the dealer, the same problem was there again: loss of power steering. This is so dangerous. I've noticed tons of other people have this same complaint and it should be a recall issue and fixed.

The contact owns a 2012 Honda Civic. The contact stated that while exiting a parking structure, the vehicle failed to accelerate, the steering column started to fail, and the vehicle began to make an abnormal sound coming from the front driver’s side. The vehicle was towed to the local dealer where it was diagnosed as having a shredded C-axle and transmission failure. The vehicle was not repaired. The manufacturer was made aware of the failure and referred the contact to the NHTSA Hotline for assistance. The failure mileage was approximately 140,000.

My airbag warning light comes on intermittently. When the light is on, the airbags are non-functional. It comes on at various times while driving, and at various speeds. The official diagnosis is a flaw in the "internal resistance in driver's airbag inflator." This is a well-established problem in this model, and Honda offers extended warranty coverage for the passenger side airbag for this problem. Yet Honda refuses to take any responsibility or action for the drivers side with the same issue. Numerous other manufacturers have issued recalls or other corrective action for the same part.

We were making a left turn, and a SUV ran the red light across the street and ran through the intersection hitting us broadside at about 45 mph. We were traveling at about. 20-30 mph as we were going to the freeway onramp and had to get to speed. The SUV impact was by the front passenger side tire or just after. The impact was hard enough to bend the subframe to the left. The side air bags did not inflate. We have always had issues with the child safety sensor in the front passenger seat, could that have been the reason? The passenger in the seat was about 105 -110 lbs. and hit the door panel and glass as a result of the air bags no deploying. The hit was bad enough it killed the engine and the frame damage further disabled it.

Like others, I have had an airbag warning light appear intermittently. Apparently, my VIN is affected by this even though this and Honda's website indicates there are 0 recalls for my car. Dealership informed me that this indeed is a recall issue.

Airbag system appears

The exhaust pipe fell off the catalytic converter. Upon some research on the internet, I have found that this is a common issue for this specific car model.

Light for Air Bag System fault keeps intermittingly coming on. I know it was a problem in the civic until 2011 but I have a 2012 and it may have been an issue or this year as well.

While driving at about 40 mph the car suddenly started to pull toward the left. I pressed on the brake pedal as I steered to the right to try to bring the car back to my lane but I noticed the brake pedal was already very hard. In a second the car skidded out of control toward the right side of the road and it slammed its left side against some big rocks. The driver's door window broke and the side airbags deployed. The big rocks kept us from going into the water of a lake that the road runs next to. The passengers in the car were myself and my wife and were not injured but it was a very terrifying incident and the consequences could have been a lot worse. The vehicle has been released to Progressive, the Insurance Company.
