NHTSA Defect Investigations for the 1998 Buick Century
The Office of Defects Investigations (ODI) is an office within the NHTSA which investigates serious safety problems in the design, construction or performance of vehicles. The NHTSA is authorized to order manufacturers to recall and repair vehicles, if the ODI finds a safety issue. NHTSA investigations for the 1998 Buick Century, both ongoing and closed, are listed below:
POWER RACK AND PINION STEERING FAILURE NHTSA Engineering Analysis #EA03019
Steering:Rack And Pinion
Summary: GM's letter to NHTSA dated December 11, 2003, expands its original recall (NHTSA 02V286) to include certain w-body vehicles: 96-97 olds cutlass supreme; 98 olds intrigue; 97-98 olds cutlass; 97-98 Chevy lumina, Monte Carlo and Malibu; 96 Pontiac Grand Prix; and 96-98 Buick regal.the number of vehicles recalled is 750,283.GM determined that failure of the rack and pinion is related to damage of the lower pinion bearing and the level of the pinion bearing pre-load spring force.GM states, "higher rack pre-load spring force (133 lb.) is the design characteristic most closely associated with higher bearing damage rates in most of the vehicle applications that used the general bearing company (gbc) bearing."all of the vehicles covered in the expanded recall have the 133 lb spring force.the 96 lumina/Monte Carlo and 97-98 Century w-body vehicles included in this investigation utilize a lower spring force and are not included in the recall.

POWER RACK AND PINION STEERING FAILURE NHTSA Defect Investigation #RQ03001
Steering:Rack And Pinion
Summary: GM conducted a safety recall (NHTSA # 02V286) to address a steering defect pertaining to a lower pinion bearing (lpb) within the rack and pinion steering gear (R&P). The recall covered 1,159,156 model year 1997-1998 Pontiac Grand Prix vehicles built between March 1, 1996 and October 31, 1997, 1996-1998 Pontiac trans sport, Chevrolet lumina apv, Chevrolet Venture, Oldsmobile Silhouette minivans, and Chevrolet cavalier and Pontiac sunfire sedans built between January 1, 1996 and October 31, 1997.ODI opened this rq after receiving reports that other vehicles were exhibiting the same symptoms as the recalled vehicles.based on ODI's review of technical and complaint data collected during the rq, the w-cars are associated with either a higher steering complaint rate or a higher lpb failure rate than the other vehicles investigated under the rq and are above or near the rates for the recalled vehicles.thus, ODI will further examine the w-cars (1996-1997 Oldsmobile cutlass supreme, 1996-1998 Buick regal, Chevrolet lumina, Chevrolet Monte Carlo, 1997-1998 Buick Century, and 1998 Oldsmobile intrigue) under a new investigation, engineering analysis (ea)03-019.

WINDSHIELD WIPER NHTSA Engineering Analysis #EA99024
Summary: By letter dated December 12, 1999, GM notified NHTSA of its plans to conduct a safety related defect campaign to remedy 155,149 of the subject vehicles.the vehicle population for the campaign includes the 1997 Buick regal/Century and Pontiac gran prix models built during the period from the start of production through May 1, 1997.GM determined that the wipers installed prior to this date could stop working, usually during heavy load conditions, due to separation between the drive pin and the crescent in the wiper crank arm assembly.effective May 1, 1997, GM corrected this problem in production by modifying the drive pin and strengthening the crescent.these same improved parts will be installed in the vehicles to be recalled.the scope of the campaign will include all vehicles produced prior to the May 1, 1997 correction (the Oldsmobile intrique production did not start until after May 1, 1997, and is therefore not included).vehicles with the scope of this investigation and produced after May 1, 1997, contain the more robust crescent and improved pin design and are not included in the recall campaign.ODI will continue to monitor complaint reports on the vehicles produced after May 1, 1997 and reserves the right to take further action if warranted by the circumstances.based on GM's recall action (ODI 99V-348) this investigation is closed.
