Fiat 500 shows mixed reliability in German vehicle inspections

The Fiat 500 remains one of the best‑selling mini cars, with ADAC reporting over 1.5 million units sold worldwide. Since its 2007 launch the model has expanded into several variants – the 500C convertible, the 500L seven‑seater, and the all‑wheel‑drive 500X – and offered a range of engines including gasoline, diesel, LPG, mild‑hybrid and, from 2024, hybrid and electric versions. Production of the pure‑combustion version ended in mid‑2024, but hybrid and electric models continue.

German technical inspections (HU) reveal a mixed picture. Strengths noted by the Auto Bild TÜV‑Report 2026 include a sturdy chassis, reliable steering, minimal rust and durable brake lines. However, the ADAC inspection data shows recurring faults: joint and axle issues, lighting failures, oil leaks, brake‑system problems, exhaust‑pipe concerns, and accelerated brake‑disc wear. Older cars also often fail emissions tests (AU). In ADAC’s reliability ranking, models from 2019 onward rate as “reliable”, while those from 2013‑2015 are deemed “unreliable” and cars from 2008‑2012 and 2016‑2018 score “average”.
