I've had plenty of Buick in the bay over the years, and the fuel-system complaints on these don't surprise me. 121 on the NHTSA record across 13 model-year entries (2005–2010) is not a fluke. The 2006 Buick Rainier leads the list but the pattern shows up across multiple years and models. Not a one-off. 1 crash report on file. Not a high count, but the failure mode has put owners in the position to file. Average shop fix runs about $1,200 — not catastrophic, but it adds up over time. Across the 75 complaints reporting odometer mileage, the median failure lands at about 60,225 miles. Check the fuel pump access cover for prior work. A vehicle on this list that already had a pump replacement is a vehicle to consider — the work is done.
