Known faults to check
TransmissionHigh
Powershift clutch judder and shudder
- Typically appears
- 60,000+ miles
- What to inspect
- Pull away from cold and feel for shudder
ElectricalMedium
Door lock actuator and central locking faults
- Typically appears
- Age-related
- What to inspect
- Lock and unlock every door several times
SuspensionMedium
Rear beam bush wear causing wandering
- Typically appears
- 80,000+ miles
- What to inspect
- Check for tracking wear and wandering on the motorway
Engine / CoolingHigh
Rapid coolant loss and overheating on 1.6 EcoBoost models due to degas pipe failure.
- Typically appears
- 40,000-70,000 miles
- What to inspect
- Check the coolant expansion tank level and inspect the thin plastic return hose routing over the engine for brittleness, cracks, or signs of recent replacement.
Body / InteriorMedium
Water ingress causing damp smells and condensation, usually from failed rear pressure relief vents.
- Typically appears
- 5-8 years
- What to inspect
- Lift the boot floor carpet and check the spare wheel well for standing water, rust, or dampness. Check for a musty smell in the cabin.
Electrical / InfotainmentMedium
SYNC 2 or SYNC 3 screen freezing, blacking out, or dropping Bluetooth connections due to APIM failure.
- Typically appears
- 50,000-80,000 miles
- What to inspect
- Start the engine, attempt to pair a phone via Bluetooth, and test the sat-nav map loading speed. Sluggish response or failure to pair indicates a failing APIM.
Engine / Fuel SystemMedium
Exhaust fumes in the cabin and a ticking noise from the top of the 1.6 TDCi engine.
- Typically appears
- 60,000-100,000 miles
- What to inspect
- Remove the plastic acoustic engine cover while idling. Listen for a rhythmic chuffing sound and look for black, tar-like carbon deposits around the injector bases.

Check this exact carFrequently asked questions
Should I avoid Powershift?
Not automatically, but budget for clutch work without records.
What is the wet belt risk?
Failure can destroy the engine, so belt evidence is non negotiable.
Are manuals safer?
Yes, manual EcoBoost cars are the lower risk buy.
Is the TDCi DPF system reliable for short urban journeys?
Like most modern diesels, the 1.5 and 1.6 TDCi engines require regular motorway runs to perform active DPF regeneration. If the vehicle has been used primarily for short urban trips, the DPF will clog, leading to limp mode and expensive replacement. Always check the service history for forced regenerations.
What should I look out for on the Grand C-Max sliding doors?
The rear sliding doors on the Grand C-Max are prone to roller bearing wear and track debris accumulation. This causes the doors to stick, drop slightly, or fail to latch correctly. Ensure both doors open smoothly with one hand and check the lower runners for damaged nylon rollers.
Are there any common issues with the manual gearboxes on diesel models?
While generally robust, the six-speed manual can suffer from dual-mass flywheel wear on diesel variants. Listen for a distinct rattling noise at idle that disappears when the clutch pedal is depressed. A heavy clutch pedal also indicates the assembly requires imminent and costly replacement.
