2009 Pontiac Montana

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2009 Montana.

The 2009 Pontiac Montana is a minivan that rounds out the final model year of this nameplate before Pontiac's discontinuation, representing the culmination of a design lineage that had evolved considerably over its production run; while specific powertrain details for this particular model year are not catalogued in the available data, the Montana carried forward the front-wheel-drive architecture and versatile three-row packaging that defined the segment. Examining the complaint trajectory from the preceding decade reveals a striking downward trend: filings peaked at 262 in 1999 but had fallen dramatically to just 1 by 2008, indicating that whatever initial issues plagued earlier iterations had been substantially resolved through engineering refinements and manufacturing improvements. This places the 2009 Montana at the end of a reliability recovery curve, suggesting that prospective owners would benefit from the corrected issues that plagued the nameplate's earlier years while acknowledging the inherent uncertainties of any vehicle approaching the end of a model's production lifecycle.

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.
