Engine And Engine Cooling Problems of Honda Civic - part 1

The head gasket was failing and the spark plugs were enduring spark blowout and the car was misfiring occasionally I tried entering the highway and as I was merging to the highway and getting up to speed the car suddenly starting flashing the check engine light and wouldn’t accelerate anymore when I gave it gas as I was entering the highway and a big truck towing vehicles was coming so I had to get to the emergency lane and stop the vehicle and the trucker had to slam on his brakes when my car was supposed to accelerate it completely shut down and started slowing down. Causing a dangerous situation.

I was driving on a very busy road and the car completely died and would not go into park. It was like the battery was not even there. The steering wheel locked up, hazards would not come on and all the doors locked and would not unlock. There was no power to the car whatsoever. The drivers side door had to be pried open from the outside so I could get out of the car. We had the battery tested and is tested completely fine. The car has done this three times now.

Vehicle experienced sudden and complete loss of engine power while driving in active nyc traffic. Without any warning lights or prior symptoms, the engine shut off mid-motion, the accelerator became unresponsive, and the car stopped moving in the middle of a busy roadway. I lost all propulsion and had to activate hazard lights while stuck in live traffic. This created a severe safety hazard for me and surrounding vehicles. The vehicle could not be safely moved, and no police or roadside support was able to reach me for over an hour. This incident placed me at high risk of being struck by oncoming traffic. This is the second major failure with this vehicle. On day 2 of my lease, the car experienced multiple system malfunctions related to an open recall, causing the vehicle to fail on the highway. That recall repair did not prevent this new failure. After this most recent incident, aaa diagnostics showed the vehicle was not drivable, and the dealership later informed me that the failure involves a deeper fuel system/high-pressure pump issue. They stated there is no guarantee the vehicle will operate normally even after repair, yet on 12/10/25 they attempted to return the car to me and told me to continue driving it despite knowing the defect is safety-related. As of today, I have been without a safe vehicle for over 10 days, and neither the dealership nor Honda corporate has provided a loaner or safe transportation. My initial safety case with Honda was also prematurely closed without my knowledge, and multiple attempts to escalate to a supervisor were unsuccessful or delayed. A vehicle that stalls without warning at speed is an extreme safety hazard, and this defect remains unresolved. I am reporting this because the vehicle has failed twice under dangerous conditions, and the manufacturer has not ensured that the vehicle is safe to operate.

The engine and electrical/power train system malfunctioned, causing the vehicle to stall, shut off, and shake without warning. The failure results in complete loss of power and inability to move the vehicle. This defect has occurred multiple times and has been inspected by the dealership over five occasions, but the problem has not been fixed.

I was driving 35 mph toward a busy intersection when I lost my brakes and power. A service message “ima check systems” light lit up on the dash. I lost brakes and power while entering an intersection putting myself and other drivers in danger of an accident narrowly missing a container truck. The car shut off with my front end in the intersection. I was able to restart the car and drive it to the nearest garage. They connected the code machine to the vehicle showing “p1437. ” I then had my car towed to the nearest Honda dealership. They told me my VIN was not listed under service bulletin 20-030 even though my car fit all of the parameters and showed the same code(s). After giving me a quote of $1900+ to fix the issue, they are claiming to have fixed the problem but I am questioning if the real issues were fixed and if I am responsible for any costs.

The hybrid motor DC to DC convert failed. When this fails it stops providing 12 v power to the rest of the vehicle resulting in multiple systems stopping or working very slowly. This vehicle does not have a traditional alternator. There was a TSB and an extended warranty offered to some models, but not all included in the VIN range for this vehicle. The vehicle was scanned and pulls the same codes as the TSB notes as the issue.

The contact owns a 2016 Honda Civic. The contact stated that while the vehicle was running with the a/c unit activated, there was an abnormal odor inside the cabin of the vehicle. Additionally, while the a/c unit was activated, only hot air was coming from the vents. The vehicle was taken to a dealer, where it was diagnosed and determined that the a/c evaporator needed to be replaced because of leaks in three places. The vehicle was not repaired. The manufacturer was notified of the failure and a complaint was filed. The failure mileage was approximately 106,000.

I received an email from Honda regarding a safety recall, stating that the defective part is now available. However, when I called different Honda dealerships, they told me to disregard the notice because the part is not available. If the repair cannot be done, I am concerned why Honda sent the notice in the first place.

I am filing a safety complaint regarding my 2017 Honda Civic hatchback and the dangerous issue related to its air conditioning (a/c) system — a problem affecting many Civic owners nationwide. I initially brought my vehicle to Honda city chicago for a Honda “campaign” repair (a term they use instead of calling it a recall) in 2023 and again this year, related to the a/c system. I was told the issue would be resolved. However, after agreeing to an optional transmission oil change they recommended, I was later told the a/c still wasn’t fixed — and that I now needed to pay $400 for a diagnostic. That diagnostic revealed the actual problem: a locked a/c compressor. (which they knew they just wanted the money) this defect is not just an inconvenience — it’s a serious safety hazard. When the a/c is turned on, the locked compressor causes the engine to shake violently and stall completely. This happened to me at a red light; the car shut off, became unresponsive, and I was stuck blocking traffic. If this had occurred while driving at higher speeds, the consequences could have been catastrophic. Many Civic owners have reported similar compressor failures leading to engine stalls and unsafe driving conditions. Honda is aware of this issue but continues to treat it as isolated rather than a systemic defect. I urge the NHTSA to open a formal investigation into this widespread and dangerous issue involving locked a/c compressors in 2016–2020 Honda Civics. A safety recall is warranted before more drivers are put at risk or harmed due to this known defect.

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.

- what component or system failed or malfunctioned, and is it available for inspection upon request? my 2006 Honda Civic engine overheated. Upon diagnosis it was found that radiator coolant had leaked out due to cracks in the engine block (short block). Engine malfunction. - how was your safety or the safety of others put at risk? my teenage son drives this car and initially he did not notice coolant leak. Engine can stop working while driving on a freeway (seized engine) which is a very serious safety risk. - has the problem been reproduced or confirmed by a dealer or independent service center? yes, local Honda dealer confirmed the problem and pointed me to a service bulletin 10-048 from american Honda (https://static. Nhtsa. Gov/odi/tsbs/2017/mc-10115157-9999. Pdf) that noted this exact manufacturing defect. American Honda had provided extended warranty to allay customer fears at the time but without a recall. - has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? it was inspected by a Honda dealer, tracy Honda at California. It was also inspected by another local auto shop and had the same finding. I am attaching those documents. - were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? no warning signs. The issue was first observed on June 29, 2025.

On over a dozen occasions my vehicle’s check engine light randomly comes on and then my car stalls out while driving and begins decelerating quickly. It is very dangerous and scary when this has happened on the freeway or in places where there is nowhere to pull off the road. My Honda Civic is less than 2 years old and has already been in the service department at Honda for a combined total of more than 30 days. Honda keeps trying to replace things but the issue keeps happening and they haven’t been able to properly diagnose or fix the problem. It is unsafe to drive this car and Honda has been unable to fix it. I bought this car brand new with 0 miles and the issues started early on before I reached 20,000 miles. I attached one of the most recent invoices from Honda where they noted the fuel injectors failing and codes of misfires in all cylinders. They most recently tried replacing the fuel injector but it still hasn’t fixed the problem. This car is unsafe to drive and has been in the shop multiple times for more than 30 days for the same issue that they can’t seem to fix.

- the engine failed. The engine block warped and both had to be replaced. I have pictures from the dealer. The cost was $8,194. 56 at the dealer for a replacement engine with 89k miles on it. - my son's safety was put at risk because he is in a rural area. Every warning lamp on the dashboard turned on after indy Honda replaced the coolant (maintenance minder a125). Then the lights would turn off. Then andy mohr Honda inspected it (for the first time) and their diagnosis was a pvc pipe crack. We paid for that repair. The second time was the head gasket and the engine was destroyed. - the problem was confirmed by andy mohr Honda and indy Honda in the state of indiana. Andy mohr confirmed the turbo engine for the Honda Civic has a known issue and than we should have purchased the 2. 0 liter instead of the 1. 5 liter because of the load the turbo puts on the engine. American Honda motor CO. , inc disagrees and stated there was no issue. - the vehicle was inspected by the manufacturer via pictures taken at andy mohr Honda. - prior to the coolant service in June 2025 there were no warning lamps. There were no symptoms. The Civic has only been maintained by Honda dealers. The first time (approximate date) we noticed the issue: June 23. My son videoed it. Please note the text from andy mohr Honda stating the engine was overheated. The coolant was replaced by indy Honda a week prior to the overheating. It should not have occurred.

While driving the dash showed a "12 volt battery charging system problem. " continued to drive to a safe location roughly a mile down the road and while enroute all the error lights illuminated and proceeded to state "tire pressure monitor problem" "brake system problem" "brake hold system problem" "power steering problem" and a couple others I don't recall. I lost my power steering while driving and my wipers proceeded to stop working, in a downpour. Contacted aaa who came and ran diagnostics which showed the alternator was dead. I then had to have my vehicle towed instead of driving it to work.

I brought my car to the dealership Honda north at 382 newbury street in danvers MA on 6/5/25 to repair NHTSA recall number 23v-858. The vehicle was returned to me on 6/7/25 at which time I was told the interior would have a strong fuel smell for 1-2 days, but that would disappear. After 4 days, the fuel smell worsened and the "check engine" light had come on. On 6/11/25 I returned the vehicle to Honda north. When I picked up the vehicle several days later, the fuel odor was minimal, and the check engine light was off. Today [xxx], the check engine light is back on. I plan to call Honda north to schedule what will be my 3rd visit to Honda north for this safety recall repair, which clearly is not being repaired properly, and putting me in further danger of crash or injury.

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.

The engine gasket failed, leaking coolant into cylinder 3. This created misfires while the vehicle was driving, leading to unpredictable loss of power while driving. Eventually, the coolant purged unbeknownst to the driver and created overheating conditions while driving which could have led to complete engine failure on the road. This behavior was confirmed and reproduced by an independent shop, wenmac repair, in hardin county, ohio. They replaced the spark plugs and coils, thinking the misfire was not necessarily related to the head gasket. The vehicle was then taken to Honda development and manufacturing of America, llc's official repair center for Honda associates attached to Honda's marysville auto plant 10/1/25 and diagnosed by a Honda master technician. My fiance and I both directly work for Honda. It is currently having the head gasket replaced at a cost of $2,700. 00 plus taxes. The vehicle is still in the shop. The failure was observed on vehicle first around 150,000 miles.

Air conditioner stopped working - I heard the condenser has a 10 year warranty extension - regardless of mileage. Please assist [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Signs of head gasket failure at approximately 67,000 miles.

Came to a stop at a stoplight, auto idle stop was in use and the engine failed to start again. The car acted like the battery was dead and everything turned off.

Engine has a crack block on the front. It is a known issue but it is past the warranty that Honda offered. I think they should extend the warranty more.

Engine block cracked. Leaking coolant and rendering vehicle useless.

Engine failure while driving down the highway. Was able to safely get off the highway without being able to accelerate. Car was towed to the Honda dealership where all the maintenance has been done. They said the car had a cylinder misfire and would need the engine replaced. It would cost $13,000. This car had already had the a/c, fuel pump and transmission replaced in the five short years I owned it. It was garage stored and had under 50,000 miles. All the maintenance was done through a certified Honda dealership.

Few months afyer I bought this car brand new it started leaking oil from valve cover gasket. Took the car u to dealer I was told its normal to leak out which surprised me to hear from service that ots normal to leak oil from calve cover gasket. It was replaced. At 70k miles I syarted seeing oil seeping through bell housing but it wasn't alot so I though it might have spilled during oil change. At 110k miles it is leaking alot and after taking it to repair shop im told that its leaking from rear main seal and its leaking onto hot exhaust. Unfortunately Honda wont cover this because of the mileage. Hondas used to be reliable but not anymore.

Went to my local dealer on January 11 to have my car checked due to a possible knock in my engine or transmission. They checked it but was not able to find a code or the actual cause after changing the oil of transmission and running it. It still continues to have issues they told me “might need to leave your car overnight because their master technician is not here until Monday “ to me I didn’t like much that answer because I spend too much for a no fix or cause. Also they could not provide me a loaner as well which was not a good idea no codes in the system or lights in the dashboard , it started a day before I took it to the shop.

My husband and I purchased a 2015 Honda Civic 3 years ago. We have maintained proper maintenance and have the documentation on this. At 118,000 ish miles, my [xxx] son was merging onto the interstate at night just a day or so after a snowstorm. As he was merging the car unexpectedly began to lose power. He tried to compensate by pushing the gas harder but realized her needed to pull over. The merge lane had construction cones and there was a bank of snow on the shoulder prohibiting him from getting over safely. He contacted the police he came out and he contacted a tow truck. He had to sit at the end of a merge lane for 45 minutes before a police officer could get there. We are fortunate he was not plowed by a semi or other vehicle. The car was towed to richmond car & truck center. After inspection, it was determined a new motor was needed. We paid to have that replaced only to be told after that it was still not operable. The transmission was out. The likely-hood of a motor and transmission going out was practically unheard of. The mechanic was even at a loss. I researched and found my son's make/model did have a recall on the transmission although, his was not part of that. We are thankful he is safe but I have never heard of a Honda losing a transmission/engine at 118,000 miles. We believe this is a transmission flaw. No warning light was ever illuminated and no issues of a problem ever existed until this incident. We have documentation. This has been reported to Honda but I have not received a response. I fear this may happen to someone else. What options do we have? information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
