Summary

The 2002 Alfa Romeo 166, while admired for its styling and driving dynamics, suffers from several common reliability issues. Engine problems such as timing belt and turbocharger failures can be severe and costly. Transmission problems, particularly with synchro wear in the manual gearboxes and slipping in the automatic, are also prevalent. Electrical gremlins and suspension issues further contribute to the overall maintenance burden. While some repairs are relatively inexpensive, others can be quite costly, making ownership potentially expensive, especially if deferred maintenance is needed.
