2017 Ford Mustang Complaints

ELECTRICAL SYSTEM — Filed 07/13/2026

Horn when first pushed does not work....Push it 3-4 times rapidly and it works fine...Intermittent....Yesterday a kid not paying attn pulled out in front of me on a bicycle....I hit the horn, horn did not work, came sooooo close to hitting him......With a horn operating properly it would not have been as nearly deadly as it was......Took it to my dealer, was told it is a common known problem, about $1000.00 to troubleshoot and fix....This is a extremely dangerous defect, known to everyone and should be a recall.....The expense to fix is ridiculous to the point that very few are getting it fixed and it is a continuing deadly issue.....

Our 2017 has had an ongoing problem through the years with the passenger door opening at speed. Sometimes going 70 mph on the interstate. Lately it has happened more and more. Yesterday, my wife called me at work, very upset saying that the passenger door popped open again on her way to work. I have read that Ford has had some issues with driver side doors opening, but have not seen a recall for the passenger side. This is very dangerous and scares my wife. Ford seems to be very slow with giving attention to safety issues. Last year, our rearview camera on the same car was supposed to have been repaired. They did part of the job but said they are waiting on a part. That was October of 2025. I have heard nothing back. I have contacted the dealership, who tells me they will get back with me, but they basically have not. Meanwhile, I still have a nonworking backup camera. I know they are bogged down with recalls, but these are ongoing, very serious safety issues.

This is a Mustang convertible. The doors would be open all of the sudden when the car is running especially on highway. It's not wide open but ajar. The wind would blow into the car, noisy and scary. Both doors have this issue, mainly on driver side. The passenger side also happened once on highway when my daughter was there. This typically happen in a long drive like couple of hours. The first time this happened is couple of years ago. This issue happened more and more often in the past year. I found online that this issue was reported and some of the cars were recalled. However, my car is not one of those that were recalled. I believe this is a big deal and should be taken care of seriously. Thank you.

While driving my recently purchased 2017 Ford Mustang Convertible from Florida to North Carolina, the passenger-side door repeatedly unlocked and partially opened while the vehicle was traveling at interstate speeds. This occurred approximately 12 times during the trip. The door appeared to latch normally when closed, but would unexpectedly unlock and pop open while the vehicle was in motion. This created a significant safety concern due to the risk of occupant injury, driver distraction, and potential loss of vehicle control. I am aware that Ford has issued recalls related to door latch failures on certain Mustang models; however, my vehicle's VIN is not included in the recall population. Based on my research, numerous owners of Ford Mustang Convertibles from model years around 2017 have reported experiencing similar door latch and door-opening issues. Given the frequency of the occurrences and the obvious safety implications of a vehicle door opening while traveling at highway speeds, I believe this issue warrants further investigation.

Recall performed and tech stated parts were bad and needed desperately and parts were ordered. I have a repair invoice to prove it in my vehicle history. I rescheduled appointment for recall completion and service manager was very rude and stated recall doesn’t even have parts out until 11/2026. When I questioned if recall was performed improperly per TSB she placed me on hold for a while and she said parts department doesn’t have parts for me /never ordered anything and I can’t get the recall done.
