2006 Buick Allure

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2006 Allure.

The 2006 Buick Allure carries a straightforward service profile defined by its 5.5-quart 5W-30 API engine oil specification, the figure that anchors its routine maintenance needs. From a reliability standpoint, the model year posts a notably thin complaint ledger—just four total owner concerns filed, with exterior lighting emerging as the most frequently cited trouble area—and it has never been subject to a recall campaign. That pairing of low complaint volume and zero recall action positions the 2006 as one of the quieter entries in the Allure's documented track record. For a researcher mapping the nameplate's dependability arc, this year stands as a relatively calm data point worth weighing against the surrounding model years.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the spark plugs every 100,000 mi; coolant at 150,000 mi. The big-interval services (at 150,000 mi for coolant, and the transmission fluid) are the ones owners most often skip — on a lower-mileage example, assume the original fluids are still in it and check them first.

Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

Owner complaints about the 2006 Buick Allure lead in one area — the exterior lighting, 1 of 4 reports (25%), well ahead of the next concern. NHTSA has issued no recalls for this vehicle, so these are owner-reported concerns only. 0 of the reports describe a crash and 0 a fire — a small share of the total, but worth weighing against the exterior lighting pattern above. These are tallies of what owners actually reported to the federal government, not an editorial score — and higher-selling models naturally rack up more reports.
