6 Most Common Ford S-Max Problems
These are the faults most frequently seen on the Ford S-Max by UK garages — ranked by how commonly they occur and how much they cost to fix.
Depending on engine variant, the S-Max uses either a timing belt (older TDCi) or chain (newer units). Belt replacement intervals must be respected. Chain models can develop rattle on cold starts.
💷 Typical repair cost: £350–£1,200
The 2.0 TDCi S-Max shares the Galaxy's DMF weakness. A judder on pull-away or rattle at idle signals DMF wear.
💷 Typical repair cost: £600–£1,200
High-mileage diesel S-Max models develop EGR valve buildup causing rough running, hesitation and EML.
💷 Typical repair cost: £200–£500
AWD S-Max models can develop faults with the rear power transfer unit. Vibration under load is the main symptom.
💷 Typical repair cost: £400–£900
The S-Max's sporty setup means the front shocks work hard. Worn shocks are a frequent advisory at MOT and affect the S-Max's handling advantage.
💷 Typical repair cost: £200–£400
Older S-Max SYNC systems can become unresponsive or lose phone connectivity. Software updates usually resolve this.
💷 Typical repair cost: £0–£200
