Suspension
55 reports5 crashes1 related recall
“In 2017 had my front control arms replaced after the driver side CV arm came off of the axle due to a recall. 5 years later (about 30k miles) the same exact situation happened now with the passenger side making a left turn. Thankfully both times I didn’t cause an accident but came close due to the wheel coming off of the axle. Brought to dealership, they had to get approval from corporate for the repair. Got a call 6 days later saying corporate denied the goodwill repair due to being “normal wear and tear” and they told me to call corporate. Just called corporate and they say that the dealership makes that decision. I shouldn’t have to pay for something that was recalled, repaired, and happened again 100% in the same fashion. Normal wear and tear on a CV arm is not 20-30k miles.”

Service brakes
23 reports
“While driving the vehicle the brakes became hard to depress and a hissing came from my steering column, the car would not stop or respond to stop. I had to downshift to Neutral to get the speed slow enough to stop - and had passed through an intersection while in failure. I had also had symptoms I did not know at the time may be related which was at a stop at dunkins or a drive through at a stopped position - where the car would run rough the last few weeks. I thought the rough idle was gas related. I can no longer drive the vehicle and am told this is brake booster/pump issue / that other of the same parts in fords and other manufacturers are now extending customer sat programs like 13N02 because of faulty parts in the brake booster. the vehicle can be towed or seen for this problem. The vehicle has no existing coverage of the faulty brake booster. This is a car insured for my son [XXX][ to drive and It is a safety risk that this went while driving, i'm happy it was myself driving that day. Problem has been confirmed as a brake booster pump/booster failure by a service professional. No warning lights - just not able to stop the car when stepping on the brake. Thanks”
