The best and worst Chevrolet Avalanche years, by the numbers
Short answer: among Chevrolet Avalanches old enough to judge (2005–2013), the 2005–2006 and 2012 have the fewest owner complaints per 10,000 sold. The 2007–2008 have the most.
We counted every owner complaint filed with the federal government (NHTSA) for each model year and divided by how many were sold that year, so a year that sold more doesn’t look worse just for being popular. Years newer than 2013 are shown but not ranked — they haven’t been on the road long enough. How this is calculated.
