Vehicle: FORD CROWN VICTORIA View model page

NHTSA investigation EA03012 is a Engineering Analysis opened on 2003-07-25 and currently closed. The subject of record is FORD CROWN VICTORIA, which places this file inside the Office of Defects Investigation queue for FORD. Latest activity on this investigation was logged on 2005-04-11 — 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 EA03012 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 A LETTER DATED FEBRUARY 25, 2005, FORD MOTOR COMPANY (FORD) NOTIFIED ODI THAT IT WOULD BE CONDUCTING A CUSTOMER SATISFACTION PROGRAM (FORD NO. 04B26) TO CORRECT A REAR BRAKE LINE CHAFING CONCERN IN APPROXIMATELY 44,00..." 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 FORD files, listed below, give context on whether this is an isolated concern or part of a broader pattern across the brand.

Investigation Summary

IN A LETTER DATED FEBRUARY 25, 2005, FORD MOTOR COMPANY (FORD) NOTIFIED ODI THAT IT WOULD BE CONDUCTING A CUSTOMER SATISFACTION PROGRAM (FORD NO. 04B26) TO CORRECT A REAR BRAKE LINE CHAFING CONCERN IN APPROXIMATELY 44,000 MODEL YEAR (MY) 1997 FORD CROWN VICTORIA AND GRAND MARQUIS NON-FLEET VEHICLES EQUIPPED WITH ELECTRONIC TRACTION CONTROL THAT WERE BUILT AFTER MARCH 19, 1997. THESE VEHICLES HAVE AN ADDITIONAL REAR BRAKE LINE AND A MASTIC PATCH CAUSING REDUCED CLEARANCE FROM A STIFFENING RIB IN THE FLOOR PAN. ODI¿S ANALYSIS SHOWED HIGHER COMPLAINT AND WARRANTY RATES RELATED TO REAR BRAKE LINE FAILURES IN THIS POPULATION THAN IN OTHER SUBJECT VEHICLES AND PEER MID-SIZED PASSENGER CARS THAT WERE EVALUATED DURING THE INVESTIGATION. VEHICLES INVOLVED IN FORD¿S PROGRAM WILL HAVE THE REAR BRAKE LINES INSPECTED FOR CONTACT WITH THE FLOOR PAN STIFFING RIB. IF THERE IS CONTACT, BUT NO ABRASION OR LEAKAGE, THE BRAKE LINES WILL BE REPOSITIONED. IF THERE IS ABRASION OR A LEAK IS EVIDENT THE BRAKE LINE WILL BE REPAIRED. IF NECESSARY, BOTH OF THE REAR BRAKE LINES WILL BE REPLACED. THOUGH FORD DOES NOT ADMIT TO A SAFETY-DEFECT IN THE SUBJECT COMPONENTS, ODI BELIEVES THAT THE FACTS IN THIS INVESTIGATION SHOW OTHERWISE BECAUSE THE INSUFFICIENT CLEARANCE IN THE ROUTING OF THOSE BRAKE LINES MAY RESULT IN LEAKS IN THOSE LINES THAT MAY RESULT IN INCREASED STOPPING DISTANCES. ODI IS DESIGNATING THE CAMPAIGN A SAFETY RECALL (NHTSA RECALL NO. 05V-086). BECAUSE OF THE LOW RATES OF BRAKE LINE FAILURES IN THE REMAINING SUBJECT VEHICLES, A SAFETY-RELATED DEFECT HAS NOT BEEN IDENTIFIED IN THOSE POPULATIONS AND FURTHER USE OF AGENCY RESOURCES DOES NOT APPEAR TO BE WARRANTED. THE CLOSING OF THIS INVESTIGATION DOES NOT CONSTITUTE A FINDING BY NHTSA THAT NO SAFETY-RELATED DEFECT EXISTS IN THOSE VEHICLES. THE AGENCY RESERVES THE RIGHT TO TAKE FURTHER ACTION IF WARRANTED BY THE CIRCUMSTANCES. FOR ADDITIONAL INFORMATION, SEE THE ATTACHED CLOSING REPORT.

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.
