Reliability, what owners report, and what it costs to keep.
AVOIR's read: the numbers are mixed and the complaint record is worth reading before you commit.
Owners have filed 224 complaints with NHTSA about the 1999 Buick LeSabre, and it carries 2 recalls. These are owner allegations rather than confirmed defects, but the pattern of what people complain about is the most useful signal a used buyer has.

NHTSA lists 2 recall campaigns for the 1999 Buick LeSabre. Recalls are free to have fixed at a franchised dealer regardless of who owns the car now, but only if they were never done, so check the VIN of the specific car rather than trusting the model.
VEHICLE DESCRIPTION: PASSENGER VEHICLES EQUIPPED WITH 4T65E AUTOMATIC TRANSMISSIONS. THESE VEHICLES FAIL TO CONFORM TO THE REQUIREMENTS OF FMVSS NO. 102, "TRANSMISSION SHIFT LEVER SEQUENCE." A RETAINING CLIP, WHICH SECURES THE MANUAL VALVE TO THE LINKAGE OF THE TRANSMISSION DETENT LEVER, CAN BECO
Risk: IF THE LINK DISCONNECTS, THE DRIVER'S INDICATED PRNDL STATE MAY DIFFER FROM THE HYDRAULIC STATE OF THE TRANSMISSION. IF THE DRIVER SELECTS 'DRIVE' AND THE TRANSMISSION IS ACTUALLY IN 'REVERSE', A VE
Fix: DEALERS WILL REPLACE THE MANUAL VALVE/LINK ASSEMBLY WITH A REPLACEMENT MANUAL VALVE/LINK KIT, FEATURING A SPRING-TYPE FASTENER.
ON CERTAIN PASSENGER VEHICLES EQUIPPED WITH 3800 V6 (L36) ENGINES AND CERTAIN DELPHI FUEL PRESSURE REGULATORS, THE REGULATORS HAVE A MUCH HIGHER THAN USUAL RATE OF FUEL LEAKS. A LEAK CAN ALLOW FUEL TO ENTER THE INTAKE MANIFOLD THROUGH A VACUUM LINE. IF THE ENGINE DOES NOT START WHEN CRANKED, THE
Risk: THE BACKFIRE CAN RUPTURE THE INTAKE MANIFOLD. THE RUPTURE OF THE INTAKE MANIFOLD CAN DISPLACE A FUEL LINE, PULLING AN INJECTOR OUT OF PLACE, AND CAUSING A FUEL LEAK AND POSSIBLE FIRE.
Fix: DEALERS WILL INSTALL NEW FUEL PRESSURE REGULATORS WITH IMPROVED DIAPHRAGMS. THE RECALL WILL BE CONDUCTED IN PHASED MAILINGS. PHASE 1 BEGAN ON JUNE 30, 2004, AND PHASE 2 BEGAN ON SEPTEMBER 30, 2004.

Percentile ranks against other midsize & large cars in the catalog.
What stands behind each score for this car:
Owners have filed 224 complaints with NHTSA for this model-year, and engine and engine cooling is the most reported area with 67 of them (30%). There are 2 recalls on record. Check any specific car against its VIN before buying.
AVOIR scores its reliability 75/100 (good) from NHTSA recall campaigns and complaint density. That figure is a raw complaint count, not yet adjusted for sales volume, so a high-volume model scores worse than it deserves.
AVOIR scores its longevity 76/100, but that figure is an estimate built from the powertrain and the brand's record, not a measurement. A 1999 car has no 200,000-mile population to observe yet, so treat it as a prior rather than evidence.
AVOIR's read: be careful, because the numbers are mixed and the complaint record is worth reading before you commit. Its overall ownership score is 67/100. Condition, mileage and service history still matter more than any score, so get a pre-purchase inspection on the specific car.
