2006 Honda Civic fuel system problems

FUEL/PROPULSION SYSTEM

I have a 2006 Honda Civic GX compressed natural gas vehicle. The problem with the vehicle is the compressed natural gas cylinder that holds the fuel. The cylinders are only certified for a period of time 15 or 20 years. After that the cylinders are considered expired and must be replaced. Once they are expired, they cannot be recertified. The problem I encountered is a complete lack of knowledge of proper maintenance procedures even by Honda dealers that are certified to work on natural gas vehicles (NGV). See Honda Service Bulletin 06-015 1998-2015 Civic GX All and US Dept of Energy, Alternative Fuels Data Center - CNG Fuel System and Tank Maintenance. From the time I bought the vehicle in 2006 until 2024 I regularly took it to a certified Honda NGV service dealer. At no time did they perform any required NGV safety checks. My issue is that there may be many of these vehicles on the roads still that pose a real safety risk to the owner and public if the NGV fuel systems have not been properly maintained. I brought this safety issue up to the Honda dealer and Honda Motor Company and both declined to take any measures to alert current NGV owners or Honda certified NGV service dealers. If expired cylinders are still in service, they are at risk of exploding and causing significant damage and injury.

FUEL/PROPULSION SYSTEM

My fuel tank all of a sudden started leaking. It all started as a gradual issue. Very random and unusual. I always get this car serviced. Honda denies any part of the defect and was informed car does not qualify any warranty at 93k miles. Tank had cracked and this is unusual for a lightly driven car. First signs were gas fumes all over the garage. Consumer had a local shop check the car there were no leaks. Consumer had 0.5 of the tank filled.

FUEL/PROPULSION SYSTEM

FUEL GAUGE OPERATES INTERMITTENTLY. GAUGE MAY SHOW AS 'FULL' WHEN EMPTY; OR INDICATE 'EMPTY' WHEN FULL. AT TIMES, GAUGE LIGHTING IS OFF AND WILL NOT REFLECT EITHER 'FULL' OR 'EMPTY' FUEL TANK. HAS ALSO INDICATED AS CONTAINING FUEL IN TANK, WHEN IN REALITY IS NEAR EMPTY, WHICH MAY CAUSE DRIVER TO RUN OUT OF FUEL WITHOUT SUFFICIENT WARNING.

FUEL/PROPULSION SYSTEM

FUEL PUMPS ARE LEAKING FROM THE TOP OF PUMP HOUSING AND ARE FILLING UP THE CUBBY HOLE THAT THEY SIT IN, WITH GAS. THIS PUMP HAS A ACCESS HOLE UNDER THE REAR SEAT AND FUMES CAN BE SMELLED INSIDE AND OUTSIDE OF THE CARS, WITH SOME LEAKING ON THE GROUND. IT ALSO IS KNOW TO BE ON SOME ODYSSEY AS WELL. IF PARKED IN THE GARAGE OVERNIGHT THE FUMES COULD FILL THE AREA AND BE IGNITED BY A WATER HEATER OR SOME OTHER SOURCE. I HAVE REPLACED MANY OF THESE PUMPS OVER THE YEARS AND HONDA DEALERS ARE DOING THE SAME WITH NO CONCERN THAT THEY ARE A DEFECT AND COULD CAUSE A POTENTIAL SAFETY RISK.

HYBRID PROPULSION SYSTEM: INVERTER

HONDA CIVIC HYBRID IMA BATTERY DEPLETES EVERY TIME I START THE CAR AND THERE IS NO CHARGE FOR ELECTRIC MOTOR WITH 2 MINUTES OF STARTING TO DRIVE. SO THERE IS NO ELECTRIC ASSIST WHEN ENTERING FREEWAY. THE INTERNAL COMBUSTION ENGINE IS UNDERSIZED FOR THE WEIGHT OF THE CAR AND THUS GETTING ON THE FREEWAY CAN BE QUITE DANGEROUS. ALSO HONDA ISSUED A RECALL TO "FIX" IMA BATTERY ISSUES. THIS HAS RESULTED IN SIGNIFICANTLY LOWER GAS MILEAGE THAN WAS ADVERTISED. PRIOR TO THE IMA RECALL THE CAR RETURNED 42-46 MPG AFTER THE RECALL IT NOW RETURNS 33-35 MPG.

HYBRID PROPULSION SYSTEM: INVERTER

HONDA CIVIC IMA SYSTEM NOT FUNCTIONING PROPERLY WHILE DRIVING, LEADING TO LOSS OF POWER WHEN CRITICALLY NEEDED, POSSIBLY CAUSING AN ACCIDENT. THE CAR COMPLETELY STALLED IN TRAFFIC, IMA LIGHT, CHECK ENGINE LIGHT, BRAKE SYSTEM LIGHT WERE ALL ON, CAR WOULD RESTART, BUT WOULD NOT LET TAKE OUT OF PARK TO GET OUT OF TRAFFIC! VERY VERY DANGEROUS. I HAVE COMPLAINED ABOUT THIS HYBRID BATTERY GIVING ME PROBLEMS BEFORE-- NOT HOLDING A CHARGE, ALMOST EVERY TIME I START THE CAR, THE IMA BATTERY SHOWS DEPLETED, EVEN THOUGH IT WAS CHARGED WHEN I LEFT THE CAR THE NIGHT BEFORE, AND OFTEN IT WILL GO FROM FULLY CHARGED TO DEAD IN A MATTER OF 1 MILE OF DRIVING ON FLAT ROADWAY, CAUSING THE ENGINE TO BE VERY SLUGGISH AND NOT HAVE POWER WHEN NEEDED. HONDA WOULD NOT DO ANYTHING, THEY JUST KEPT MAKING EXCUSES. THERE ARE MANY MANY PEOPLE COMPLAINING ABOUT THE SAME THING. I'M TAKING IT IN TOMORROW MORNING TO HAVE IT LOOKED AT, BUT I AM NOT CONFIDENT THEY WILL PROPERLY ADDRESS THE ISSUE, BECAUSE THEY HAVE DISMISSED ME IN THE PAST.

HAD A SOFTWARE UPGRADE IN 2009 ON MY 2006 HONDA CIVIC HYBRID, DESIGNED TO INCREASE BATTERY LIFE. MY GAS MILEAGE DROPPED BY 12 MPG, AND THE PERFORMANCE OF THE CAR, ACCELERATING INTO TRAFFIC, GOING UP A HILL, ETC, HAS DEGRADED SIGNIFICANTLY.

BOUGHT CAR IN MAY 2006, BY AUG 2006 I WAS ONLY GETTING 36 MILES PER GALLON. BROUGHT CAR TO DEALER. THEY SAID THEY REPLACED A PART TO FIX PROBLEM. PROBLEM NOT FIXED! BROUGHT CAR BACK 3 MORE TIMES AND DEALER SAID I WAS DRIVING THE CAR WRONG. I TOLD THEM TO KEEP THE CAR FOR A WEEK, THEY DID BUT STILL COULD NOT GET THE MILEAGE OVER 37 MPG. THEY TOLD US THEY DIDN'T KNOW WHAT THE PROBLEM WAS AND THERE WAS NOTHING THEY COULD DO ABOUT IT. WENT THROUGH 3 BACK TIRES ON DRIVERS SIDE. THEY STILL WOULDN'T DO ANYTHING ABOUT IT! I HAD TO PAY FOR IT! THE CAR WAS GETTING WORSE AND WORSE. FINALLY WE TOOK IT TO ANOTHER DEALER. THEY FOUND THAT SOMETHING WAS BROKEN BY THE BACK TIRE (WHICH IS WHY I HAD TO KEEP REPLACING THEM) AND I NEEDED A NEW TRANSMISSION. ALL OF THAT WAS COVERED UNDER WARRANTY. THAT WAS IN SEPTEMBER 2010. THEY ALSO TOLD ME THAT'S WHY I NEVER GOT THE MILEAGE I WAS SUPPOSED TO GET. THAT WAS WHEN THEY TOLD ME THAT I NEEDED TO GET THE SOFTWARE UPDATE!! NOW MY CAR IS NOT DRIVABLE! THE BATTERY DOESN'T CHARGE, THE CAR CANT ACCELERATE! THE SERVICE MANAGER AND THE FOREMAN TOLD HONDA AMERICA THAT THE CAR IS NOT SAFE AND HONDA AMERICA DOESN'T CARE! I FILED A CLAIM AND I WAS TOLD THAT THERE IS NO PROBLEM WITH THE CAR. I JUST NEED TO GET USED TO DRIVING IT DIFFERENTLY! WHEN I PRESSED THEM AND TOLD THEM MY CAR IS NOW UNDRIVABLE, I WAS TOLD THAT THEY HAD NOTHING ELSE TO SAY TO ME! HONDA REALLY MESSED THIS ONE UP! PEOPLE ARE GOING TO GET KILLED DRIVING THESE CARS....AND THEY KNOW IT! MY CAR WAS A LEMON SINCE THE DAY I BOUGHT IT! PAID $5,000.00 EXTRA FOR IT , NEVER GOT THE MPG, AND NOW I CANT DRIVE IT!

FUEL SYSTEM, OTHER

OVER THE LAST YEAR I HAVE NOTICE REDUCED SURGE POWER WHEN I HIT THE ACCELERATOR FOR WHEN I NEED EXTRA, SHORT TERM SPEED (E.G., MERGING ONTO A HIGHWAY). WHEN I FLOOR THE GAS PEDAL, I DO NOT GET ANY "ASSIST" FROM MY IMA (HYBRID MOTOR), AS VIEWED BY THE IMA METER ON MY DASH AND FELT IN TERMS OF ACTUAL INCREASE IN POWER/SPEED. THIS IS EXACERBATED WHEN THE AIR CONDITIONING IS ON. FURTHER, I HAVE NOTICED A REDUCTION IN FUEL ECONOMY AS WELL AND THINK THAT THIS MAY BE ASSOCIATED WITH THE OVERALL ISSUE. THE LACK OF "ASSIST" IS NOT ALL OF THE TIME, BUT ONCE IN A WHILE AND A NOTICEABLE DIFFERENCE IN ACCELERATION CAPABILITIES.

FUEL SYSTEM, GASOLINE

HONDA HAS PERFORMED A SOFTWARE UPDATE ON MY 2006 CIVIC HYBRID. THE RESULTS ARE TANTAMOUNT TO HAVING REPLACED MY CAR WITH ANOTHER THAT HAS MARKEDLY INFERIOR RESPONSE, PERFORMANCE, AND GAS MILEAGE: * ABOUT 10 MPG DECREASE SINCE THE 8/4/2010 IMA SOFTWARE UPDATE * RARE IVA ASSIST ON STARTING FROM 0, RESULTING IN A NOTICEABLE LAG BETWEEN DEPRESSING THE GAS PEDAL AND MOVEMENT FROM A STOPPED POSITION - THIS IS A SAFETY ISSUE. * RESPONSIVENESS OF ACCELERATION AT HIGHWAY SPEEDS INCONSISTENT AND UNPREDICTABLE - SINCE THIS AFFECTS DRIVER REACTION AND RESPONSIVENESS THIS IS A SAFETY ISSUE NOTE: THE SOFTWARE UPDATE RENDERS THE ELECTRIC MOTOR PRACTICALLY MOOT. SINCE IN MY CASE THE BATTERY DROPS ITS CHARGE RADICALLY OVER A 24 HOUR PERIOD IF NOT USED, THE UPDATE APPEARS TO BE DOING LITTLE MORE THAN PREVENTING AN ALREADY COMPROMISED BATTERY FROM FAILING.

I HAVE A 2006 HONDA CIVIC HYBRID. FOR THE PAST SIX OR SO MONTHS SOMETIMES WHEN I ATTEMPT TO ACCELERATE AFTER A STOP OR AFTER SLOWING DOWN THE IMA BATTERY INDICATOR WILL DROP TO 1 OR NO BARS WITHIN A SECOND OR TWO. WHILE THIS IS HAPPENING AND FOR AT LEAST 1 MINUTE AFTERWARD I HAVE ALMOST NO POWER AND CAN BARELY ACCELERATE. THE LOSS OF POWER IS SO BAD THAT I HAVE NARROWLY AVOIDED CRASHES. THIS HAPPENS RANDOMLY, BUT MORE AND MORE FREQUENTLY. WHEN IT DOES HAPPEN, MY MPG ALSO DROPS QUITE A BIT. SINCE IT IS IMPOSSIBLE TO PREDICT IT MAKES DRIVING VERY HAZARDOUS. I HAVE ALSO NOTICED THAT THE CAR IS NOT GOING INTO AUTO-STOP AS OFTEN AS IT SHOULD BE. I HAVE TAKEN THE CAR TO TWO HONDA DEALERSHIPS AND BOTH HAVE SAID THAT THEY CAN'T "DUPLICATE" THE PROBLEM AND THAT NO "CODES" ARE COMING UP. THE FIRST DEALERSHIP DID NOTHING. THE SECOND ONE, WHICH WAS WHERE THE CAR WAS PURCHASED "RESET THE COMPUTER" BUT NOTHING ELSE. THE CAR HAS BEEN GIVEN BACK TO ME BOTH TIMES AND THE PROBLEM HAS CONTINUED.

FUEL SYSTEM, GASOLINE

THE IMA SYSTEM ON THE 2006 HONDA CIVIC HYBRID IS SLOWLY DISINTEGRATING. THE FUEL ECONOMY HAS PLUMMETED AND THE BATTERY CRASHES INTERMITTENTLY RENDERING THE CAR A HIGHWAY MENACE. I DOUBT THAT DRIVING THE CAR WITHOUT THE IMA IS LEGAL IN ANY STATE. IT IS A RECIPE FOR DEATH AND DISASTER. I URGE A COMPLETE INVESTIGATION INTO AMERICAN HONDA WHO WON'T EVEN ADMIT THAT THERE IS A PROBLEM. IF THAT WERE THE CASE, THEY WOULD NOT HAVE DEVELOPED PCMS (COMPUTER PATCHES ) IN AN ATTEMPT TO DEAL WITH THIS ISSUE.
