1995 Oldsmobile Aurora problems

What is wrong

Some passenger vehicles equipped with 4.0l v8 engines have a condition in which the nylon tubing used in the fuel rail construction may degrade and crack. Additionally, the 1995 model year uses a unique underhood fuel return line that may crack. Cracking of the fuel rail or return line tubing can result in a fuel leak into the engine compartment.

Risk

Fuel leakage, in the presence of an ignition source, could result in a fire.

Remedy

Dealers will inspect and, if necessary, replace the engine fuel rail with a new stainless steel fuel rail. Dealers will also install a revised chassis fuel return line. The recall began on june 2, 2004, for 1996-1997 oldsmobile aurora vehicles. Owners of 1995 cadillacs and 1996-1997 oldsmobile aurora were sent letters on august 6, 2004. Additional letters to owners will be forthcoming. Owners should contact oldsmobile at 1‑800‑630‑6537.

Recall number 04V110000 · Recall details

What is wrong

Vehicle description: passenger vehicles. The rear shoulder belt(s) do not retract. A retainer could separate from a rear seat shoulder belt retractor which results in the retractor return spring becoming disengaged.

Risk

In a crash, an occupant may receive more severe injuries if there is excessive slack in the shoulder belt.

Remedy

Dealers will inspect both rear shoulder belt retractors for correct function and install a spring cover retaining strap to each retractor. If a retractor does not function correctly, it will be replaced.

Recall number 00V057000 · Recall details

On march 3, 2004, general motors notified odi that it was recalling approximately 94,000 my 1995-97 oldsmobile aurora vehicles equipped with 4.0l v8 engines (rpo l47 - vin8 c) to address concerns with underhood fuel leakage from cracked fuel rails and, in some of the vehicles, cracked fuel return lines. According to gm, the nylon tubing (pa12) used in the fuel rail construction in these vehicles may degrade and crack.gm's supplier attributed the cracking to the combined effects of heat, time, alcohol fuel, fuel pressure cycling, and design stresses.in addition, gm stated that the my 1995 aurora uses a unique underhood fuel return line that may also crack at unusually high rates.gm dealers will install a new fuel rail constructed out of stainless steel in all of the recalled vehicles and will also install a revised chassis fuel return line in the my 1995 auroras. On april 16, 2004, general motors notified odi that it was adding approximately 389,000 my 1995-97 cadillac seville, deville and eldorado vehicles equipped with 4.6l v8 engines (rpo's ld8 and l37 - vin8 y and 9) to recall 04v‑110.the recalled cadillacs will receive the new stainless steel fuel rails.this engineering analysis is closed.

The fuel rail assemblies used in the subject vehicles were manufactured by dana.the fuel rail jumper tubes were made of monolayer nylon 12 (pa12).in model year (my) 1998, the jumper tube material was changed from pa12 to m-bond (a multi-layer ptfe/pa12).in addition, all service parts produced since the end of production 1997 use the m-bond jumper tubes. Material analysis performed by dana on failed fuel rails showed that the mono-layer nylon 12 jumper tubes are susceptible to environmental stress cracking (ESC).gm believes the ESC is a result of heat, time, alcohol blended fuel, fuel pressure cycling, and designed in stress. Eight of the gm complaints are duplicative of odi complaints.odi has received 77 of it's 123 complaints in the past 12 months.fuel rail part sales over the last three years range from 3.0 percent of production for the my 1997 cadillac vehicles to 13.1 percent for the my 1995 auroras.at least one of the fire incidents occured while the vehicle was parked within a garage attached to the consumers home.the fire resulted in damage to the dwelling as well as the total loss of the vehicle.this investigation has been upgraded to an engineering analysis.

In its letter dated february 25, 2000 to the federal safety agency, general motors stated that it will conduct a safety recall of 85,253 model year 1995 buick riviera and oldsmobile aurora vehicles for the defect in the outboard rear seat belt retractor assemblies.

EA00006

Complaints generally stated that one or both outboard rear seat belts do not retract at all and are useless.it is evident that the seat belts do not provide any tension and have excess slack.the retractor assembly has a plastic cover next to the retractor return spring.according to general motors (gm), heat may soften, warp and deflect the plastic spring cover allowing the return spring to disengage through and jam in the spring cover access hole rendering the return spring nonfunctional.to elimanate the problem, gm changed the spring cover material and access hole at the beginning of production of model year (my) 1996 buick riviera and oldsmobile aurora vehicles.both complaints and warranty claims have declined significantly from my 1995 subject vehicles to my 1996 vehicles.
