Open the full vehicle complaint log (all categories)My vehicle has a check engine light. The code indicates the issue is the fuel neck filler (part number 17660-S3VA02) which has been confirmed by my mechanic. This is a safety item due to some type of fuel leak in the filler neck area for gasoline which causes the check engine light. The part is on backorder and from my conversations with multiple dealerships, there is no estimated date of delivery. Apparently, there is a high number of vehicles having this issue. As a result, I am unable to smog my vehicle due to some type of fuel leak. It appears there is a safety item that needs to be addressed immediately.
I HAVE HAD TO REPLACE THE FUEL FILLER PIPE 3 TIMES BECAUSE IT LEAKED FUEL VAPORS AND CAUSED THE CHECK ENGINE LIGHT TO COME ON. ALL 3 PART REPLACEMENTS WERE GENUINE ACURA PARTS. THE REPLACEMENTS TOOK PLACE IN 2010(METRO ACURA), 2013(DAN'S MOBILE AND SMOG STATION) AND 2016(DAN'S MOBILE AND SMOG STATION). THE LAST FAILURE WAS CAUSED BY THE CRIMPING OF THE METAL GAS CAP FITTING TO THE PLASTIC FUEL FILLER PIPE DURING THE PART MANUFACTURING PROCESS. THE CRIMPING WENT THROUGH THE PLASTIC AND CAUSED THE FUMES TO LEAK. THESE FUMES ARE VERY NOTICEABLE IN THE CABIN OF THE CAR AND CREATE THE POSSIBILITY OF EXPLOSION. ALL 3 REPLACEMENTS HAVE COST ME ABOUT $500. I REPORTED THIS MATTER TO ACURA CLIENT SERVICES BUT THEY WERE UNCONCERNED.
