Product Safety - Engine Fuel Rail-Replace

THIS BULLETIN IS BEING REVISED TO ADD 1997 CADILLAC MODEL VEHICLES. PLEASE DISCARD SAFETY RECALL BULLETIN NUMBER 04014B, DATED SEPTEMBER 2004.

General Motors has decided that a defect which relates to motor vehicle safety exists in all 1995-1997 Cadillac DeVille Concours, Seville and Eldorado, 1996-1997 Cadillac DeVille; and 1995-1997 Oldsmobile Aurora model vehicles. These vehicles have a condition in which the original equipment nylon tubing used in the fuel rail construction may degrade and crack. Additionally, the 1995 Oldsmobile Aurora uses a unique underhood fuel return line that may crack at unusually high rates. Cracking of the fuel rail can result in a fuel leak into the engine compartment. The operator may experience fuel odor and possibly engine stalling due to loss of fuel pressure to the engine. If this event were to occur, and if an ignition source were present, an engine compartment fire could occur.

Dealers are to inspect and, if necessary, replace the engine fuel rail with a new stainless steel fuel rail. Dealers will also replace the chassis fuel lines on 1995 Oldsmobile Aurora model vehicles.

Involved are all 1995-1997 Cadillac DeVille Concours, Seville and Eldorado, 1996-1997 Cadillac DeVille; and 1995-1997 Oldsmobile Aurora model vehicles; and built within these VIN breakpoints:

Important: Dealers should confirm vehicle eligibility through GMVIS (GM Vehicle Inquiry System) before beginning recall repairs.

For US

For dealers with involved vehicles, a Campaign Initiation Detail Report containing the complete Vehicle Identification Number, customer name and address data has been prepared and will be loaded to the GM DealerWorld, Recall Information website. Dealers that have no involved vehicles currently assigned will not have a report available in GM DealerWorld.

For IPC

For dealers with involved vehicles, a Campaign Initiation Detail Report containing the complete Vehicle Identification Number, customer name and address data has been prepared and is being furnished to involved dealers. Dealers that have no involved vehicles currently assigned will not receive a report with the recall bulletin.

The Campaign Initiation Detail Report may contain customer names and addresses obtained from Motor Vehicle Registration Records. The use of such motor vehicle registration data for any other purpose is a violation of law in several states/provinces/countries. Accordingly, you are urged to limit the use of this report to the follow-up necessary to complete this program.

Dear General Motors Customer:

This notice is sent to you in accordance with the requirements of the National Traffic and Motor Vehicle Safety Act. Federal regulation requires that any vehicle lessor receiving this recall notice must forward a copy of this notice to the lessee within ten days.

General Motors has decided that a defect which relates to motor vehicle safety exists in all 1995-1997 Cadillac DeVille Concours, Seville, Eldorado, 1996-97 Cadillac DeVille; and 1995-1997 Oldsmobile Aurora model vehicles. These vehicles have a condition in which the original equipment nylon tubing used in the fuel rail construction may degrade and crack. Additionally, the 1995 Oldsmobile Aurora uses a unique underhood fuel return line that may crack at unusually high rates. Cracking of the fuel rail can result in a fuel leak into the engine compartment. The operator may experience fuel odor and possibly engine stalling due to loss of fuel pressure to the engine. If this event were to occur, and if an ignition source were present, an engine compartment fire could occur.

Your dealer will inspect and, if necessary, replace the engine fuel rail with a new stainless steel fuel rail. Oldsmobile dealers will also replace the chassis fuel lines on 1995 Oldsmobile Aurora model vehicles. This service will be performed for you at no charge .

This service correction will take approximately one hour, and the service correction for the 1995 Oldsmobile Aurora will take an additional 50  minutes. However, due to service scheduling requirements, your dealer may need your vehicle for a longer period of time.

To limit any possible inconvenience, we recommend that you contact your Oldsmobile dealer as soon as possible to schedule an appointment for this repair. By scheduling an appointment, your dealer can ensure that the necessary parts will be available on your scheduled appointment date.

Should your dealer be unable to schedule a service date within a reasonable time, you should contact the appropriate Customer Assistance Center at the number listed below.
