SteeringHigh
Bent or snapped inner tie rods causing excessive steering play and uneven tyre wear, particularly on Sasquatch-equipped models.
- Typically appears
- 10,000-30,000 miles
- What to inspect
- Turn the steering to full lock. Visually inspect the inner tie rod boots for tearing or obvious bends, and rock the front wheels at 9 and 3 o'clock to feel for excessive play.
DrivetrainMedium
Gear oil leaking from the front CV axle seals where the half-shafts enter the front differential housing.
- Typically appears
- 15,000-40,000 miles
- What to inspect
- Kneel beneath the front bumper with a torch. Look directly at the front differential housing where the axles enter, checking for dark, oily residue or active fluid drips.
Cooling SystemMedium
Coolant loss and overheating on 2.3L EcoBoost models due to premature water pump failure or weeping seals.
- Typically appears
- 30,000-50,000 miles
- What to inspect
- Open the bonnet and check the coolant expansion tank level. Shine a torch down the front of the engine block to look for pink or orange crusting around the water pump weep hole.
Body/ElectricalLow
Frameless door windows failing to drop when the handle is pulled, causing the glass to catch on the weather seals.
- Typically appears
- 5,000-20,000 miles
- What to inspect
- Rapidly open and close each door using the outside handle. Verify the glass drops a few millimetres instantly before the door opens, and seals tightly under the roof lip upon closing.

Build my inspection planFrequently asked questions
Is the Ford Bronco reliable?
Later builds improved, but early 2021 cars had engine and hardtop issues — check history carefully.
Does the Bronco have engine problems?
Some 2.7L EcoBoost units suffered valve failures; confirm warranty or repair records.
What should I check on a used Bronco?
Engine history, hardtop condition, transmission feel and infotainment.
Are there any specific rust or corrosion issues to look out for?
While the aluminium body panels resist traditional rust, the steel ladder chassis and exposed suspension components are prone to surface corrosion. This is especially true for grey imports exposed to UK salted roads without aftermarket underseal. Always inspect the chassis rails, weld seams, and bash plates for premature oxidation.
How does the Sasquatch package affect tyre wear and running costs?
The Sasquatch package includes 35-inch mud-terrain tyres which wear rapidly on tarmac, often requiring replacement by 25,000 miles. These oversized tyres also place additional strain on the steering rack and suspension bushes. Dealers should budget for higher preparation costs, as replacing these specialist tyres is highly expensive.
What are the common MOT failures for imported Bronco models?
As most Broncos are left-hand drive imports, common MOT failures revolve around non-compliant lighting. Ensure the headlamps have been properly converted for UK left-hand traffic to avoid beam pattern failures. Additionally, check that a rear fog light has been correctly retrofitted and wired to an illuminated dashboard switch.
