Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

2012 Honda Civic Owner Comments

problem #10

Civic 4-cyl

  • 20,000 miles


On approximately 10 occasions, after refueling the Honda Civic gx (natural gas) vehicle, the car would start up and travel no more than 100 yards from the filling station. The gas gauge reads empty even though the tank is full. There are pressure regulators and safety valves that open up with a thunk sound when the car is started after filling. In each case when the car has stalled, the valves/regulators do not open up with the thunk sound. This has been happening for the last 1.5 years with the 2012 Civic gx. There is no pattern to when this occurs or doesn't, but, it usually happens in a cluster of times and then goes away for 5-6 months. Reading online forums, this seems to happen to vehicles that are much older and Honda's only solution is to replace the valves and regulators. As my vehicle is still under warranty, they have been reluctant to do anything. From corporate Honda, they are blaming the drivers for leaving the key in the ignition in the acc position. I know that for 9 out of the 10 incidents, the key was not in the ignition. The stalling of the car has posed a dangerous situation when I was pulling out into traffic only to have the car stall due to lack of gas in the fuel line (safety valve is located in the rear of the vehicle) as it sucks what it can from the fuel line to the valves. It usually takes about 40-45 minutes for the system to reset and allow the car to run. It will run fine until some future refueling. This does not appear to be easily repeatable.

The car loses power when going up hills and has stalled twice. If I lightly bump the shift while driving it goes into neutral. I must use the emergency brake when parked even on a flat surface or the car will roll.

This has happened more than once. When descending a hill after letting up on gas pedal the vehicle will rev up for a few of seconds and hitting the brakes did not disengage throttle, also when passing another vehicle after pulling in and let up on pedal the car still revved up for a couple of seconds. Have not taken to a dealer yet as I am trying to find exactly how and when this problem occurs so I can get the dealer to reproduce this problem (speed, road conditions, and any other conditions that might cause this problem). As we all know they can never get the problems to reproduce.

Turned key to start and nothing happened; some warning lights went off, but no sound from starter, solenoid or other engine parts. Released key and turned key to start again; on second try, engine started properly. Sometimes, I may turn the key twice with nothing happening and engine starts on third try. Happens intermittently; can happen when engine is cold or hot.

The contact owns a 2012 Honda Civic. The contact stated that while driving 50 mph, the contact smelled gasoline fuel as the vehicle stalled. Upon further inspection, the contact discovered that all of the fuels leaked out of the vehicle. The fire department was called to secure the fuel leak and the vehicle was towed to a dealer. The dealer stated that a rodent had chewed through the fuel line and caused the fuel leak. The dealer repaired the fuel line. The failure mileage was 14,000.

I am a fuel efficient driver, drive with the econ button on mos of the time. I drive 150 miles 5 times a week. Every time I am going downhill and I push the brakes to slow down, the RPM's go up. I also tried driving without the econ to see if it would change and the same thing happened. You would think by hitting the brakes a little harder would do the trick to decrease speed, but it doesn't. as you start holding the breaks for a long time, then the rps would decrease. I have looked online and many people are saying the same thing. Example:

There is no accident, here is problem: I have 6840 miles on a 2012 Honda Civic LX 4dr. When fuel tank filled to all the way, the fuel was slapping about front to back while hit brake or parking. It makes a loud noise and fuel slam into the wall of fuel tank. I went to Honda local dealer and they tell me this is normal, you are not first one to complaint, but there is no service bulletin to it. This is unsafe, 10 gal gas flow in tank will throw off the balance while you make turns, or cause damage sensors in the tank, or cause fuel system leak even fire.

You can hear the fuel moving around the gas tank and banging against the gas tank walls whenever I stop. It is most severe when the tank is full. I complained to the Honda dealer where I purchased the vehicle about the noise. The dealer let me know that the noise I was hearing was the fuel moving around in the fuel tank, due to a design change in the 2012 model which removed the fuel tank baffles. The dealer will not fix this issue on my car. I called and wrote to Honda directly complaining about this issue and requesting resolution and they have not responded.
