Air bags

245 reports26 crashes1 fire4 related recalls
“I am reporting a safety hazard and a failure by Ford Motor Company to properly remedy the mandatory Takata Airbag Recall. Following the recall repair, a technician reassembly error left the airbag warning light permanently illuminated, meaning my Supplemental Restraint System (SRS) is completely disabled and will not deploy in a crash. I took the vehicle to Astro Ford in Mississippi for resolution. The Service Manager, Hunter Landry, attempted to reset the system three times and confirmed a permanent safety fault exists in the exact recall area. However, Ford’s proprietary dealership software is actively blocking the dealer from pulling the diagnostic codes or proceeding with the repair without a corporate override code. Ford Corporate customer service agents have repeatedly refused to route this request or issue the override code to the dealer, effectively blocking the repair of a failed federal safety recall component. The dealer requires a corporate email sent to [email protected] to authorize the diagnostic waiver and bypass the software block. Ford's corporate refusal forces me to drive an unsafe vehicle with no working airbags. Desired…”

Steering

22 reports3 crashes
“The contact’s brother owns a 2014 Ford Mustang. While the owner was driving at an undisclosed speed, the vehicle drifted over to the left, crossed into the other lanes, drove into a ditch, and crashed into an object at the end of the ditch, causing the vehicle to become airborne. The vehicle landed in a nearby field and came to a complete stop. The contact stated that after several impacts, the air bags deployed. The contact stated that due to the impact, the driver was unable to state what had caused the vehicle to drift over to the left before crashing into the ditch. The driver received injuries to the lower body, L1 vertebrae, chest, and a fractured back. Medical attention was needed, and the driver remained in the Intensive Care Unit. A Police report was filed. The vehicle was towed to a tow yard and remained at the tow yard with extensive damage. The contact was informed that collision coverage was required to repair the vehicle. The contact was unsure if the vehicle was deemed a total loss. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was unknown.”

Engine

18 reports2 crashes
“the following problem happened to me a few years ago (twice within a couple of months) and again, 2 days ago. Each time I was standing at a traffic light when all of a sudden it accelerated at full throttle. I practically stood on the brake pedal, but the car was inching forward, as I put the transmission into park. This was not a subtle situation, it was dangerous. The engine went from idle to screaming within 2 seconds. I ruled out the floor mat as it was in the proper position and snapped into the floor. It did not cause any warning lights to come on. in May, I had the oil changed, at which time they suggested that they clean the throttle body, which they did.They never heard of the above problem.”

Service brakes

13 reports2 crashes
“I currently own a 2014 Mustang GT with a manual transmission and notice my emergency brake release button was cracking. The button is made of cheap plastic and the dealer does not have a replacement release button. They only sell the whole emergency brake, which I feel that Ford should she be responsible of replacing the emergency brake button, since this is a safety issue that you cannot engage the emergency brake or disengage the emergency brake button when parking your vehicle on a hilly driveway or any hill at all. Which I leave in Northern California that is very hill and feel that if my car ever comes disengaged out of 1st gear it would cause serious damages to others, such as crashing into a building or other cars or even a fatality.”
