On the 2021-2024 Ford Bronco, multiple Bronco owners report a brief but pronounced rattling or knocking noise on cold start caused by worn or defective cam phasers, often accompanied by timing chain slack. Ford issued service guidance for EcoBoost engines using updated phaser parts. While some vehicles only exhibit noise, others progress to rough running, check-engine lights, or repeat repairs if only partial components are replaced.

This issue also affects: Audi A4, Audi A5, Audi A6

Common Symptoms

Rattle or knocking noise for 1-5 seconds on cold start
Check engine light
Rough idle after startup
Repeat noise after prior repair

How to Fix

Diagnosis typically involves confirming cold-start rattle after an overnight soak and checking for timing-related fault codes. Repair usually requires replacement of the affected cam phasers and, depending on wear and service guidance, timing chain-related components. Updated OEM parts are preferred because early revisions have shown repeat failures in some cases.

What Owners Are Using

On the 2021-2024 Ford Bronco, owners of lifted or Sasquatch-equipped Broncos have reported front CV axle clicking, grease sling from torn boots, and vibration under load, especially after off-road articulation or suspension modifications. Even on stock vehicles, the steep operating angles on some setups appear to accelerate outer joint or boot wear. Left unaddressed, the axle can lose grease and develop severe joint play.

Common Symptoms

Clicking when turning
Grease on suspension components or wheel well
Vibration during acceleration
Clunk from front drivetrain off-road

How to Fix

Inspect both front half-shafts for split boots, grease leakage, and play at the inner and outer joints, especially after off-road use. Replacement of the affected CV axle assembly is the usual fix; alignment and suspension geometry should also be checked. Vehicles with aftermarket lift components may need corrected angles or upgraded axles to prevent repeat failures.

What Owners Are Using

On the 2021-2024 Ford Bronco, multiple Bronco owners reported sudden loss of power steering assist, often accompanied by warning messages and very heavy manual steering effort at low speeds. The issue has been tied to failures in the electric power steering system and steering gear/rack assembly, and Ford issued a safety recall for certain vehicles because an internal steering gear component could fail and cause loss of steering control. Owner complaints and forum reports describe intermittent assist loss first, then complete failure requiring rack replacement.

This issue also affects: Ford Transit, Ford Mustang, Cadillac Escalade ESV

Common Symptoms

Power steering assist fault message
Very heavy steering effort
Intermittent steering assist loss
Steering wheel jerks or binds
Warning lights on dash

How to Fix

Scan the PSCM/ABS modules for steering-related faults and inspect for active recalls or field service actions before replacing parts. Dealers typically replace the steering gear/rack assembly and perform module calibration; in intermittent cases, wiring and connector checks at the rack and battery voltage verification are also important. If recall coverage applies, the repair should be completed through Ford rather than paid out of pocket.
