Example complaints

“Wile driving 40 mph, the right rear tire locked up and I had to counter steer aggressively to avoid spinning out and hitting oncoming traffic. The car was flat bed delivered to Ford and they recommended the following repairs. Control Arm- Rear: rear suspension lateral links. The rear upper and lower control arms not only provide suspension travel but also secure the rear end to the vehicle. *Tires - 4: passenger rear inner sidewall damaged.”

NHTSA complaint #11740622, filed 2026-05

“While driving in a 35mph zone, a complete loss of braking was experienced while coming up to an intersection. The vehicle was unable to stop, not even emergency brake function worked. An independent service center did a postmortem of the brake caliper and confirmed the fastener failure of the caliper bracket. The caliper fasteners sheared off inside the caliper resulting in the caliper piston falling apart while driving. This resulted in complete brake malfunction, and brake fluid leakage. There was no warning or message for this failure. …”
