Known faults to check
ElectricalMedium
48V mild-hybrid battery and start-stop faults
- Typically appears
- 40,000+ miles
- What to inspect
- Watch for stop-start refusing to engage and warning messages on start-up
BodyworkMedium
Tailgate and boot 'megabox' drainage water ingress
- Typically appears
- Any
- What to inspect
- Lift the boot floor and feel for damp in the megabox
BrakesLow
Rear brake corrosion from low usage on hybrid cars
- Typically appears
- Age-related
- What to inspect
- Inspect rear discs for scoring and lipping
SuspensionMedium
Creaking or clunking from front strut top mounts
- Typically appears
- 30,000-50,000 miles
- What to inspect
- With the engine running and vehicle stationary, turn the steering wheel fully lock-to-lock. Listen for spring binding, groaning, or clunking noises from the front suspension turrets.
Interior/ElectricalMedium
SYNC 3 infotainment system freezing or black screen
- Typically appears
- 3-5 years
- What to inspect
- Start the ignition and test the touchscreen responsiveness. Cycle rapidly between radio, navigation, and settings. Engage reverse gear to check for camera lag or a black screen indicating APIM module failure.
TransmissionHigh
Hesitation or jerky shifts on 7-speed Powershift automatic
- Typically appears
- 40,000-60,000 miles
- What to inspect
- With the engine warm, shift repeatedly between Park, Reverse, and Drive. Perform a quick pull-away test on the forecourt to feel for delayed engagement, shuddering, or harsh gear selection.
Engine/CoolingHigh
Coolant leaks from expansion tank seams or return pipes
- Typically appears
- 40,000-70,000 miles
- What to inspect
- Open the bonnet and inspect the plastic coolant expansion tank for hairline cracks along the moulding seams. Check the surrounding hoses and undertray for pink, crusty dried coolant residue.

Check this exact carFrequently asked questions
Does the Puma have a timing chain?
No, a wet belt in oil. Treat missing belt history as a priced-in job.
Is the mild hybrid a problem?
Not usually, but a failing 48V battery throws warnings and puts buyers off on the test drive.
What should I check in the boot?
The megabox drain. Standing water there is a common and easily missed fault.
Are there specific checks required for the 1.5-litre Puma ST?
Focus on the exhaust active valve mechanism, which frequently seizes or rattles, and check the front limited-slip differential for fluid leaks if the Performance Pack is fitted. Additionally, ensure the engine idles smoothly, as coil pack failures and rough running are documented on heavily driven examples.
What are the correct service intervals for the 1.0 EcoBoost?
Ford mandates routine servicing every 18,000 miles or two years, whichever comes first. However, due to the sensitive nature of the oil pump and internal components on these engines, independent specialists strongly recommend annual oil changes using the exact Ford-specification lubricant to prevent premature wear.
Is the 7-speed automatic gearbox reliable?
The 7-speed Powershift dual-clutch transmission is generally robust but can suffer from software glitches or clutch pack wear. Jerky low-speed behaviour or delayed engagement are the main warning signs. Always ensure the transmission shifts seamlessly between park, drive, and reverse without hesitation during your initial inspection.
