Known Ford XR6 faults
Every fault below is documented specifically for this model — researched and verified before it’s published.
The Barra 4.0L I6 uses a hydraulic primary timing chain tensioner that is oil-pressure dependent. The one-way check valve inside the tensioner can fail, allowing the tensioner to bleed down when the engine is off and the chain to go slack on restart. High-mileage engines also see wear in the timing chain itself and the plastic chain guides, compounding the slack. A failed tensioner left unrepaired risks catastrophic timing chain jump or snap.
Symptoms to notice
Loud chain slap noise on cold start, deeper and more rhythmic than VCT phaser rattle
Rattle or slap sound from front of engine that does not fully disappear on warm-up
Engine hesitation or misfire if chain has jumped a tooth
Check engine light with misfire or cam correlation codes after chain jump
What to check
On a fully cold start, listen for a loud chain slap (deeper and more rhythmic than phaser rattle) from the front of the engine that persists for more than 3–4 seconds. Check for any history of tensioner or chain replacement. Look for oil sludge on the dipstick which accelerates guide wear. Any example above 200,000 km should be considered high-risk without documented tensioner service.
Where to look: Front of engine behind timing cover, driver side
Ask the seller
“Has the timing chain or tensioner ever been inspected or replaced?”
“Is there any record of oil sludge or extended oil change intervals that could accelerate guide wear?”
“Has the engine ever made a chain-slap noise on cold start?”
02Rear Differential Carrier Bushing Wear (IRS)
MinorCommonSuspension $300–$900 to fix
The FG/FGX Falcon's independent rear suspension mounts the differential carrier to the subframe via large rubber bushings that deteriorate with age, heat cycling, and aggressive use. When the bushings degrade, the differential can shift under load, causing clunking on throttle application and lift-off, imprecise rear-end feel, and accelerated halfshaft CV joint wear from the resultant misalignment. Performance-oriented or high-mileage examples are most affected.
Symptoms to notice
Clunk or thud from rear on hard acceleration from rest
Clunk on lift-off or engine braking at low speed
Imprecise or vague rear-end feel during cornering
Vibration through floorpan under load, reducing at cruise
Accelerated CV joint wear or halfshaft vibration from differential misalignment
What to check
Have an assistant apply and release throttle in Drive while you observe differential movement — more than a few millimetres of shift indicates worn mounts. During a test drive, note any clunk or thump from the rear on hard throttle take-up from low speed. If a workshop inspection is possible: With the vehicle on a hoist, visually inspect the large front and rear differential mounting bushings for cracking, tearing, or visible separation of the rubber from the metal sleeve.
Where to look: Rear subframe — differential carrier front and rear mounting bushings
Ask the seller
“Has the rear differential mounting bushings ever been replaced or inspected?”
“Is there any clunking or banging sound from the rear during hard acceleration or when lifting off the throttle?”
“Has the car been used for towing, track days, or performance driving that would accelerate bushing wear?”

This page covers the model. Enter the plate of the actual car you’re looking at and see its year, engine, safety rating and register flags — free, no account needed.
Like any used car, it depends on the specific example and its service history. Across the 20 documented faults for the Ford XR6, the recurring problem areas are engine, cooling, and suspension. A Ford XR6 with a full service history and no signs of the issues listed on this page can be a sound buy but each one needs to be checked individually before you commit.
What are the most common problems with a used Ford XR6?
+
We've catalogued 20 known faults for the Ford XR6, covering engine, cooling, and suspension. Two are written out in full on this page. The rest — with the symptoms to notice, what to inspect, and typical repair costs for each — are free once you create an account.
How much do repairs cost on a Ford XR6?
+
Most single repairs on the Ford XR6 fall between $600–$1,800 at NZ independent-workshop rates. Some of the 20 documented faults cost less and a few cost considerably more, and no one car needs them all. Knowing which ones to look for before you view is what lets you negotiate the price down or walk away.
Should I get a pre-purchase inspection on a Ford XR6?
+
Yes. A Ford XR6 inspection focused on its known weak points is the single best way to avoid an expensive mistake. KickTyres gives you a guided, model-specific inspection plus a market valuation and negotiation figure for $17.90 far less than the cost of missing one of the faults on this page.
