Common Problems with the
2015 Toyota Avensis Mk3 (T27)

The second facelift brought further refinements and improved safety equipment, though the fundamental mechanical package was unchanged. By this point the Avensis was competing in a shrinking saloon market, and values are very reasonable for what remains a dependable family car. The 2.2 diesel risk is well-documented by now, so petrol cars command a premium.
