Ford Motor Company (Ford) is recalling certain 2021 Bronco Sport vehicles

The failure pattern owners describe

Buyer takeaway: A 2021 Bronco Sport with suspension complaints commonly reports leaking rear shocks, premature CV axle wear, and rear differential issues starting as low as 16,000 miles—some appearing under active recalls. Have any vehicle thoroughly inspected for rear suspension fluid leaks and drivetrain noise before purchase, and confirm recall status with the dealer.

Owners consistently report rear shock absorbers leaking fluid between 16,000 and 45,000 miles, often discovered during routine maintenance or noticed as the vehicle sits parked. Multiple complaints link this to NHTSA Campaign 25V025000, though some owners say the repair is still under development.

Rear differential problems appear early and range from grinding noises to complete seizure and wheel lock-up, with one owner reporting failure at 30,000 miles. CV axles—both driver and passenger side—are reported loose or worn, starting around 43,000 miles.

Front and rear suspension components like control arms and struts fail prematurely. Clicking, rattling, and grinding sounds from wheels and suspension occur across various mileages, sometimes without a clear cause even after dealer inspection.

One owner reported sudden dangerous braking on the highway with broken rear axle bolts and possible recall involvement. Another described a moaning noise specific to reverse braking after the vehicle has sat, while separate reports note rear wheel lock-up during sharp turns and heavy shaking or rattling when backing up. No warning lights appear in many cases, making early detection difficult.
