Reported issues for this Ford Fiesta
These are the most commonly reported problems on Ford Fiesta models (2017–2023), based on owner reports and workshop data across the UK.
Front wheel bearings
Insufficient sealant on driveshaft splines allows water ingress, causing bearings to crack and fail prematurely.[1] · Typical repair: £150-£300 per side (bearing + labour at indie garage, estimated).
Steering column (universal intermediate shaft bushings)
Poor-quality bushings in the sealed steering column wear out, causing play and noise.[4] · Typical repair: £400-£700 (full column replacement at indie).
Horn wiring in steering wheel
Faulty wiring chafes, shorting intermittently.[1] · Typical repair: £80-£150 (rewire/insulate at indie, estimated).
Gear selection (5MX65 5-speed manual gearbox linkage)
Worn selector mechanism or cable adjustment fails, preventing 1st/reverse engagement.[1] · Typical repair: £200-£400 (linkage adjust/replace at indie).
M1DA
Faulty sensor signal with voltage drops/spikes, misinterpreted by ECU as extra crank counts, causing misfires or injector cut-out. Likely poor contact at sensor socket or 5V reference supply vibration.
