The 2006 Alfa Romeo 156 passes its MOT first time only 68.6% of the time, well below the UK average of 80%, and a quarter of these cars have been flagged for dangerous defects—a significant concern for any prospective buyer. Petrol models fare no better at 67.4%, suggesting the reliability problem is systemic to the model rather than fuel-type specific.

These 156s are running at a modest 64,506 miles on average for their age, yet they're still racking up 4.27 failures per test and nearly 20 advisories, pointing to structural or wear issues accumulating faster than they should. If you're considering one, budget for imminent repair work and have a pre-purchase inspection focus on suspension, cooling, and exhaust systems—the usual weak spots when advisory counts are this high.

We have limited data for the 2006 Alfa Romeo 156 — treat the figures below as indicative rather than definitive.

⚠️ Over 1 in 5 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.
