I brought my vehicle into the dealer for a recall software problem and to fix an oil leak coming from the valve cover. They replace the valve cover gasket and performed the software recall. As of now it still shows that my vehicle still needs the software recall. One week later after the oil leak repair, a massive oil leak formed at the valve cover causing oil to cover my engine bay and exhaust causing a burning smell and possible fire risk. Every weekend we drive out of state to tournaments and I was unaware of the leak. I brought it back to the dealer and they said it was residual oil from the previous repair. I was skeptical but believed them. One week later the same massive oil leak and problem occurred in my engine bay and driveway. Having no confidence in the dealer and being an ASE certified master mechanic, I decided to fix the problem myself by replacing the plastic valve cover assembly. I remove the old valve cover and found it to be extremely warped not providing a proper seal. The first time I brought my car into the dealer the service advisor said this is the second one this week that we’ve seen. I have a hard time believing that my vehicle is the only problem with this. I am extremely dissatisfied with the service from the dealership and the lack of concern that my life and my sons life was put in danger with a fire risk. I am currently seeking reimbursement for the part that I paid out-of-pocket. About US$150.

While travelling at highway speeds, rainy weather, the engine completely shut down. Engine light illuminated. Did not want to pull over on shoulder so glided to exit ramp.

I took to my dealer and they tried to recreate but could not. They also found no codes. Had my family in car when full power loss. Very dangerous situation. I immediately activated the flashers.

I LEASED MY VEHICLE A YEAR AGO, I HAD ELECTRICAL ISSUES WITH MY OLD CAR SO I WANTED A BRAND NEW CAR THAT WAS RELIABLE AND SAFE FOR ME AND MY CHILDREN. IN THE FIRST MONTHS THE CAR WAS FINE BUT AFTER ABOUT 4 MONTHS THE CAR WOULD SMOKE FROM THE EXHAUST PIPES RANDOMLY. I TOOK IT FOR MAINTENANCE AS THE CAR SYSTEM DIRECTED BUT THE REPAIR SHOP NEVER SAID THERE WAS ANYTHING WRONG WITH THE EXHAUST SYSTEM. A MONTH OR SO PAST AND ONE DAY I GOT IN THE CAR AND ALL THE LIGHTS ON THE DASH BOARD WERE IN. I WAS SO FREAKED OUT BECAUSE IT WAS A NEW CAR AND NO WARNING LIGHTS SHOULD OF BEEN ON. I TOOK IT TO HONDA REPAIR SERVICES AND THEY FOUND OUT THAT A MOUSE WENT IN MY ENGINE AND CHEWED SOME OF THE ELECTRICAL WIRES. THE COST OF THE REPAIR WAS 1700 WHICH IS EXTREMELY OUTRAGEOUS PRICES TO ME. ANYWAY I WAS AT HOSPITAL AT WORK AND I GOT THE CALL FROM THE MECHANIC SAYING I WOULD HAVE TO PAY OUT OF POCKET BECAUSE IT WASN'T A FACTORY DEFAULT. SO I WENT HOME AND DID SOME RESEARCHING AND I FOUND OUT HONDA HAD BEEN USING SOYBEAN IT PEANUT BUTTER OIL TO LUBE THE WIRING, AND THAT'S WHAT ATTRACTS RODENTS TO YOUR ENGINE. IT ALSO STARTED THAT HONDA WIRE PROTECTION TAPE WAS OUT OF STOCK BECAUSE SOME MANY CUSTOMERS HAD THERE CAR WIRES EATEN BY RODENTS. SO I WAS SO PISSED OFF THAT I CALLED HONDA CORPORATE AND THEY TOLD ME THERE IS NOTHING THEY CAN DO. I FEEL AS THOUGH THIS IS A BIG SAFETY ISSUE, WHY WOULD HONDA PUT PARTS OR USE OILS IN THE CAR ENGINE THAT ATTRACTS RODENTS. THIS TO ME IS, UNFAIR TO HONEST HARD WORKING CUSTOMERS THAT PAY HONDA THERE MONEY EXPECTING TO HAVE A SAFE AND RELIABLE VEHICLE.NOW I JUST FOUND OUT THERE IS A RECALL ON THE VEHICLE BECAUSE THE CAR STARTED SMOKING OUT THE EXHAUST PIPES ONCE AGAIN. I AM VERY DISAPPOINTED IN HONDA.

2020 ACCORD 2.0T SPORT 10,600 MILES I WAS TRAVELING ACROSS THE STATE WITH PERIODS OF LIGHT AND HEAVY RAIN. ABOUT HALFWAY INTO MY ~280 MILE TRIP I STOPPED FOR A RED LIGHT. WHEN ACCELERATING FROM THE LIGHT, MY CAR LOST POWER AND THE ACCELERATOR DID NOT WORK. I COASTED TO THE SIDE OF THE ROAD AND NOTICED THE CHECK ENGINE LIGHT BLINKING, WITH NO OTHER WARNING MESSAGES. I SHUT THE CAR OFF AND RESTARTED TO FIND NO ENGINE LIGHT OR WARNING. I WAS IN THE MIDDLE OF NOWHERE LATE IN THE EVENING SO I CONTINUED TO THE DESTINATION. WITH APPROXIMATELY 20 MILES TO GO, I ATTEMPTED TO ACCELERATE AROUND A SLOWER MOVING VEHICLE AND WAS MET WITH PREVIOUS PROBLEMS, AS WELL AS MANY WARNING MESSAGES. TURNING OFF AND RESTARTING THE CAR ENABLED ME TO DRIVE AGAIN, BUT THE WARNING MESSAGES REMAIN. BOTH TIMES THIS OCCURRED IT WAS RAINING. BOTH TIMES I LOST POWER AND COULD NOT ACCELERATE TO MOVE TO A SAFE LOCATION.

FROM OCT 10 TO OCT 14, I PARKED MY CAR AT OFF AIRPORT PARKING LOT FOR 5DAYS. WHEN I CAME BACK, MY CAR DIDN'T START. MY CAR WAS TOWED TO THE CLOSEST HONDA DEALERSHIP. I GOT THE INSPECTION REPORT FROM THE DEALERSHIP STATING THAT THE REASON WHY MY CAR DIDN'T START IS DUE TO BAD GAS. I WENT TO THE GAS STATION, WHERE I PUMPED MY GAS LAST TIME BEFORE I FLEW OUT OF ATL, TO CHECK WITH THEM. THEY PROVIDED ME A COPY OF THE SYSTEM STATUS REPORT OF 10/9/20 SHOWING THAT THERE WERE NO ISSUES. SO I WENT BACK TO THE DEALERSHIP AND THEY TOLD ME THEY HAVE CONFIRMED THAT #3 CYLINDER IS FULL OF WATER; THEY SAID THEY COULD GET A FUEL SAMPLE ONCE I AUTHORIZED THEM TO WORK ON THE FUEL TANK REMOVAL AND CLEANING. ONCE THEY PROCEEDED, THEY STATED THEY FOCUSED ON CLEANING THE SPARK PLUGS AND PERFORMING AN OIL CHANGE WHICH LED THEM TO FIND OUT THERE IS INTERNAL DAMAGE TO THE ENGINE. SO THEY TOLD ME THEY WOULD STOP UNTIL MY INSURANCE COMPANY CHECKS THE CAR. THEY SAID THEY TOOK MULTIPLE FUEL SAMPLES AND DID NOT SEE WATER BUT THERE WAS WATER FILLED IN THE ENGINE CYLINDERS. THEY HAVE ASKED ME IF THE CAR WAS IN A FLOOD, BUT THERE WAS NO MASSIVE RAIN OR STORM WHICH FLOODED THE AREA. THEY EMPHASIZED THAT IT IS NOT A WARRANTABLE REPAIR AS IT IS NOT A PROBLEM CAUSED BY THE MANUFACTURER, WHICH SOUNDED QUESTIONING. THE TECHNICIAN TOLD ME IF THERE IS NOTHING WRONG WITH THE OIL AND FUEL TANK, THEN THE ONLY WAY THAT WATER CAN GET INTO THE ENGINE IS MANUALLY POURING LOTS OF WATER THROUGH AIR INTAKE, WHICH ALSO SOUNDS RIDICULOUS AS I HAVE NEVER TOUCHED IT NOR THERE WAS NO TRACE OF SOMEONE TRYING TO OPEN MY HOOD FROM INSIDE AND PUTTING WATER. AFTER I EXPLAINED TO THEM, THEY SAID THEY STILL CANNOT PROVIDE AN ANSWER AS TO WHY THERE IS WATER, BUT IT CANNOT BE WARRANTABLE REPAIR. IF THEY DO NOT KNOW THE CLEAR CAUSE OF THE ISSUES, HOW CAN THEY STRONGLY CONFIRM IT IS NOT DUE TO MANUFACTURER ISSUES?
