Recalls

3 vehicle recalls from the manufacturer. Repairs are free. Check your VIN to see if one is still open on your car.

Suspension Vehicle recall #07V270000 · 2007 · 8,800 vehicles

What's wrong: On certain passenger vehicles, a front wheel bearing and hub assembly May fracture due to improper heat treatment.

Why it matters: If a hub fractures, it May potentially detach from the wheel knuckle, resulting in the wheel being retained only by the brake caliper assembly. As a result, the wheel May separate from the vehicle potentially resulting in a crash.

The fix: Dealers will inspect both front wheel bearing and hub assemblies and replace them free of charge. The recall began on June 22, 2007.

Steering Vehicle recall #13V385000 · 2013 · 355,000 vehicles

Why it matters: If the lower bearing separates, the vehicle May experience a loss of steering, increasing the risk of a crash.

The fix: Ford will notify owners and dealers will replace the lower intermediate shaft, free of charge. The upper intermediate shaft and steering column lower bearing will be inspected to identify any damage that May have occurred as a result of lower intermediate shaft corrosion, and repaired or replaced…

Steering Vehicle recall #14V704000 · 2014 · 36,888 vehicles

What's wrong: The prior repairs May not have been correctly performed.

Why it matters: Improper servicing of the upper intermediate shaft could cause the shaft to separate, which can then result in a loss of steering control, and increasing the risk of a crash.

The fix: Ford will notify the owners of vehicles whose repair records reflect that the upper intermediate steering shaft was repaired during the course of the prior recall 13v-385. Dealers will inspect and replace the upper immediate shaft if necessary free of charge. The recall began November 17, 2014.
