Fiat 600 / 600e Common Problems & Reliability
The Fiat 600 is the B-segment crossover that replaced the 500X in UK showrooms, arriving in 2024 on the Stellantis CMP/e-CMP platform it shares with the Jeep Avenger and Peugeot 2008. It is sold as the 600e, a 54kWh front-drive EV with 156PS and a 100kW DC charging peak, or the 600 Hybrid, a 1.2-litre three-cylinder turbo petrol with 48V mild-hybrid assistance and a six-speed dual-clutch gearbox. UK trim levels are RED and La Prima, with a 10.25-inch Uconnect screen, digital instruments and a 385-litre boot. It undercuts most rival crossovers on price and is comfortable in town, but rear space is tight and the interior feels built to a price. Early cars are still under warranty, so check for software updates and charging faults rather than wear.
