A 2016 Ford Fiesta is now 10 years old, so an average example has covered around 135,000 miles. An early car in the generation · most of the launch teething issues were still being worked through, so recall completion and dealer rectification history matter. Check the state safety inspection and service history alongside the documented faults below, which are sorted by whether a 2016 car has usually reached the mileage where they appear.

Suspension knocks, corroded rear brake pipes on older cars, and worn front tyres from tracking drift.
Mk8 Fiestas with keyless entry are highly susceptible to relay theft, making them a common target. Ford introduced sleep-mode key fobs in 2019 to combat this, which deactivate after forty seconds of inactivity. Dealers should check if the supplied fobs are the updated motion-sensor type or advise buyers to use a Faraday pouch.
The 1.5 TDCi is generally robust but suffers from clogged Diesel Particulate Filters and EGR valves if used strictly for short urban trips. Check the dashboard for DPF warning lights and ensure the idle is smooth. A diagnostic scan is highly recommended to verify the soot loading levels before retailing the vehicle.
Yes. For the Mk7 ST, inspect the condition of the engine mounts, which are prone to tearing under hard acceleration. On the Mk8 ST, listen for top-end rattling indicating camshaft phaser issues. Always check both generations for signs of poor aftermarket modifications, aggressive remaps, or evidence of track day abuse.
