NHTSA Engineering Analysis EA04027 - closed, opened 2004-09-09 and involving the HONDA HONDA.
NHTSA investigation EA04027 is a Engineering Analysis opened on 2004-09-09 and currently closed. The subject of record is HONDA HONDA, which places this file inside the Office of Defects Investigation queue for HONDA. Latest activity on this investigation was logged on 2005-01-19 - NHTSA updates that field whenever an Information Request goes out, a supplement is filed, or a status change is recorded in the public docket.
An Engineering Analysis like EA04027 is the deeper technical phase that follows a PE. NHTSA requests design, warranty, and field-failure data from the manufacturer, conducts its own testing when needed, and determines whether the evidence supports a safety defect finding that would compel a recall.
Investigators summarized the matter as follows: "IN DOCUMENTS PROVIDED DURING EA04-027, HONDA IDENTIFIED A MECHANISM WHICH CAUSES THE RUBBER SEAL (GASKET) OF THE ORIGINAL EQUIPMENT (OE) OIL FILTER TO ADHERE TO THE ENGINE BLOCK OF THE SUBJECT VEHICLES. IF AN ADHERED SEA..." Investigations are the early-warning layer of the federal auto-safety system, sitting upstream of formal recalls and defect orders. Whether this one closes without action or escalates into an Engineering Analysis, the full history stays in the ODI archive so researchers, litigators, and buyers can pull the paper trail at any time. Related HONDA files, listed below, give context on whether this is an isolated concern or part of a broader pattern across the brand.
Investigation Summary
IN DOCUMENTS PROVIDED DURING EA04-027, HONDA IDENTIFIED A MECHANISM WHICH CAUSES THE RUBBER SEAL (GASKET) OF THE ORIGINAL EQUIPMENT (OE) OIL FILTER TO ADHERE TO THE ENGINE BLOCK OF THE SUBJECT VEHICLES. IF AN ADHERED SEAL REMAINS WHEN THE OE FILTER IS REMOVED AND A NEW FILTER IS INSTALLED, A "DOUBLE GASKET" CONDITION RESULTS. A SUBSEQUENT RUPTURE OF THE EXTRANEOUS SEAL CAN RESULT IN OIL CONTACTING NEARBY EXHAUST SYSTEM SURFACES AND A FIRE MAY OCCUR. THROUGHOUT ITS DISCUSSIONS WITH ODI, HONDA HAS MAINTAINED THAT IT IS THE SERVICING TECHNICIAN¿S RESPONSIBILITY TO INSPECT FOR AND REMOVE THE SEAL PRIOR TO INSTALLING A NEW FILTER. ODI¿S ANALYSIS FOUND THAT SEAL ADHESION, IN CONJUNCTION WITH TECHNICIAN ERROR AND EXHAUST COMPONENT LOCATION, RESULTED IN A HIGH RATE OF SUBJECT VEHICLE OIL FILTER FIRES COMPARED TO EARLIER MODELS AND PEERS. VEHICLES THAT HAVE NOT HAD THE OE FILTER DISTURBED ARE NOT AT RISK. SERVICE REPLACEMENT FILTER SEALS, WHICH ARE MANUFACTURED BY A DIFFERENT SUPPLIER, DO NOT EXHIBIT THE SEAL ADHESION CONDITION. THEREFORE, IF THE INITIAL OIL CHANGE IS DONE PROPERLY, THE ELEVATED FIRE RISK IS ELIMINATED FOR THE REMAINDER OF THE VEHICLE¿S LIFE. BASED ON AVERAGE MILEAGE ACCUMULATION AND OIL SERVICE INTERVAL, ODI ESTIMATES THAT MORE THAN TWO THIRDS OF THE SUBJECT VEHICLES HAVE RECEIVED THEIR INITIAL OIL CHANGE AND ARE NO LONGER AT AN ELEVATED RISK. HONDA CHANGED THE DESIGN OF THE FILTER SEAL TO PREVENT THE ADHESION CONDITION AND INTRODUCED THE NEW SEAL AT BOTH CR-V ASSEMBLY PLANTS IN DECEMBER 2004. IN A DECEMBER 8, 2004 LETTER TO ODI, HONDA COMMITTED TO SEND A NOTIFICATION TO SUBJECT VEHICLE OWNERS ADVISING OF THE FIRE RISK IF AN OIL CHANGE IS IMPROPERLY PERFORMED. THE LETTER DISCUSSES MEASURES CONSUMERS CAN TAKE TO ENSURE THE FIRST OIL CHANGE IS DONE PROPERLY. LETTER MAILINGS COMMENCED ON DECEMBER 10, 2004. OWNERS WHO HAVE RECENTLY HAD THEIR FIRST OIL CHANGE PERFORMED AND ARE UNSURE IF IT WAS DONE CORRECTLY CAN HAVE IT INSPECTED BY A HONDA DEALER AT NO CHARGE;
About This Investigation Type
An Engineering Analysis (EA) is the in-depth phase following a Preliminary Evaluation. NHTSA engineers conduct testing, collect data from manufacturers, and perform detailed technical analysis to determine whether a safety defect exists. An EA may lead to a voluntary recall by the manufacturer or, in rare cases, a mandatory recall order.
