While driving at about 75mph the passenger door unlocked and opened by itself. We got an door not closed warning light on the dash and the warning chime in addition the horn was blowing in intervals of 2 quick beeps and repeated until we were able to pull over and reclose the door. About 1 hour later same conditions the same thing happened on the drivers side. We have since discovered from the dealer that here is a campaign number of 21N10 for this issue. Holiman Ford of Maple Shade NJ took the car in right away.

I am writing to formally lodge a complaint regarding a recurring issue with the rear camera system in my 2020 Ford Mustang. When attempting to engage the rear camera while reversing, a persistent blue screen obstructs the view, posing a significant safety hazard. After conducting thorough research, I have discovered that this problem is not isolated to my vehicle alone. Instead, it appears to be a widespread issue affecting numerous owners of Ford Mustangs. It has come to my attention that the root cause of this malfunction is attributed to faults within the wiring harness of the Mustang models. What is deeply concerning is that despite the prevalence of this issue and its potential implications for driver safety, Ford Motor Company has yet to initiate a recall to address and rectify the problem. It appears that there is a conscious decision to restrict the recall, leaving countless Mustang owners vulnerable to accidents and unnecessary risks. As a responsible consumer and advocate for road safety, I implore the NHTSA to investigate this matter urgently and compel Ford to take appropriate action. It is imperative that Ford acknowledges the severity of this defect and assumes responsibility by issuing a comprehensive recall to rectify the faulty wiring harnesses in all affected vehicles. Failure to address this issue promptly not only undermines consumer trust but also jeopardizes the well-being of drivers and pedestrians alike. I trust that the NHTSA will prioritize this complaint and take decisive steps to ensure the safety and welfare of all motorists. Thank you for your attention to this matter. I eagerly await your response and resolution.

I drove my car for 22 miles, parked, and after less than one hour we heard a loud noise from the house and upon checking, we noticed the car was on fire. The fire and smoke was coming from underneath the hood (left side). The car had recent software update and the collision detection and traction control were turned-off and unable to turn it back on. Not sure if the software update had anything to do with it, but thought it would be good to mention that. The fire department came out and said it may have been electrical.

I hope this letter finds you well. I am writing to bring to your attention some serious safety issues that I have encountered with a 2020 Mustang that I purchased from CarMAX, West Valley on September 24, 2023. Soon after taking possession of the vehicle, I noticed a malfunction with the airbag system. It is disheartening to report that I had to endure a three-day wait to have the necessary repairs carried out. The delay in rectifying this crucial safety feature is highly concerning, as it exposes both the driver and passengers to unnecessary risks. Unfortunately, the problems did not end there. Shortly after the airbag issue was addressed, the engine light illuminated on the dashboard. Despite my efforts to troubleshoot the problem myself, the light remained illuminated, indicating a persisting issue with the engine. Not only did this cause me considerable inconvenience, but it also raised concerns about the overall reliability and safety of the vehicle. The most alarming incident occurred on October 2, 2023, when my car unexpectedly broke down while I was driving on the freeway. This unexpected failure not only posed a significant risk to my safety but also left me traumatically shaken by the experience. I cannot emphasize enough the fear and anxiety I felt as I navigated the dangerous situation caused by the vehicle's sudden malfunction. I am deeply disappointed by the lack of quality control and the subsequent safety hazards that have plagued my 2020 Mustang. As a consumer, I have a reasonable expectation that the vehicle I purchase will be safe and reliable. It is distressing to find myself in a situation where my safety and wellbeing are compromised due to these issues. I have taken my concerns up with CARMAX and I am waiting for a response. It is my hope that they will investigate the matter and take measures to address it. I will not stop fighting for the safety of my family and myself.

Digital instrument cluster goes blank without warning, usually when starting it up after it's been running. It takes between 10-30 minutes to come back on. Dealer doing warranty work has run through all Ford recommended tests and reinstallation of as build data - nothing works. This has happened since the vehicle was brand new; I now have 19,000 miles on it. Ford does not have a tsb for the 2020 GT Mustang with this problem. I cannot drive the vehicle without the instrument panel.
