On the 2011-2021 Fiat Uno, persistent noise from the front suspension is a recurring complaint among Novo Uno owners on Reclame Aqui and the Clube do Uno Brasil forum, frequently accompanied by interior rattles from doors, window glass and trim. Owners report knocking and creaking over bumps — often from the right front — that persists even after multiple dealer visits, including on nearly-new cars (a documented 2021-model complaint reports suspension noise unresolved after two warranty services). Brazilian mechanics' channels covering the Uno point to the stabilizer bar link/pivot (bieleta/pivô da barra estabilizadora) and worn suspension bushings as the usual culprits, aggravated by rough Brazilian pavement; the parts are cheap wear items but the noise returns periodically.
Diagnose with the car on the ground (links unloaded on a lift can mask play): typical fixes are replacing the stabilizer bar end links/pivots and stabilizer or control arm bushings, and checking shock absorber top mounts. Parts are inexpensive and widely available. For accompanying interior rattles (door panels, window glass channels), retorquing fasteners and applying felt/foam at trim contact points at a trim shop is the usual remedy — dealers rarely resolve it definitively.
