2017 Ford Mustang EcoBoost unintended downshift; potential relevance to Ford Recall 26S28 / the federal safety agency Recall 26V237 and Investigation EA26001 I am submitting a vehicle safety complaint concerning a sudden, unintended downshift in my 2017 Ford Mustang EcoBoost while traveling on Interstate 10 with my wife and son. I request that Ford investigate my vehicle and that the federal safety agency evaluate whether the lead-frame safety concern addressed by Recall 26S28 / 26V237 may also affect Mustang vehicles and other Ford models equipped with related 6R80 transmission components. On 9/26/2026, while driving on interstate I-10 in New Orleans approximately 60–70 mph, my vehicle suddenly and erratically downshifted to what appeared to be first or second gear. I could not independently verify the precise gear during the emergency. As I attempted to reach the shoulder, the vehicle remained in a low gear, which I understood to be second, and eventually entered limp mode. The abrupt change in speed and inability to accelerate normally created a near-collision situation with other vehicles traveling at interstate speeds. My wife, son, and I were placed in immediate danger. Before this event, I had noticed no signs of transmission trouble. I brought the vehicle to Supreme Ford of Slidell for diagnosis. After the dealership had the vehicle for more than a week, a service representative told me that it needed a replacement transmission costing more than $10,000. Based on my subsequent discussions with the dealership, I understood that the recommendation relied on a diagnostic scan showing a Shift Solenoid A fault. I was not provided with an explanation of additional testing establishing why replacement of the complete transmission was necessary. I returned the vehicle to my garage for further investigation. I tested all existing transmission solenoids, and all passed the testing I performed. Based on those results and my subsequent repair outcome, I identified the molded lead frame as the source.

Defect investigations
Desiccated Air Bag Inflator Rupture
From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited. The rapid burning can cause the inflator to rupture during deployment, potentially causing serious or even fatal injury to vehicle occupants. See 2016 Blomquist Report at all frontal inflators using propellant 2004 that do not contain a "desiccant" (a substance that traps and holds moisture) in US vehicles are under recall. These "non-desiccated" inflators either have been or are required to be replaced.In some cases, the remedy part for these recalled inflators was, or will be, an inflator using either propellant 2004 or 2004L that does contain a desiccant. None of these "desiccated" remedy parts (which were installed in older model year vehicles) are currently under recall for a degradation concern. Certain subsets of desiccated PSAN inflators using propellant 2004 for use as original equipment, however, have been recalled for a degradation concern. All Takata inflators produced with propellant 2004L contain desiccant, and none of these desiccated inflators using propellant 2004L are under recall for a degradation concern. There have been no reported field ruptures in any non-recalled desiccated PSAN inflators.It is understood that desiccants fully saturate at some threshold, at which point any additional moisture will not be captured. This means the degradation process observed in non-desiccated inflators using propellant 2004 may also occur in non-recalled desiccated inflators using propellant 2004, assuming additional moisture enters the inflator and high temperature cycling occurs. Based on available information, desiccant saturation can occur within the first five years in the worst environments, and the time required for full saturation is affected by multiple factors. While no present safety risk has been identified, further work is needed to evaluate the future risk of non-recalled desiccated inflators using propellant 2004.Three entities -- Takata (now known as TK Global), the Independent Testing Coalition, and Exponent -- have been studying the long-term behavior of Takata desiccated PSAN inflators using propellant 2004L (as well as 2004) in the presence of moisture and temperature cycling. The research efforts, which include development of predictive modeling techniques and field sample analysis, are ongoing. To date, none of the researchers have identified field evidence showing that propellant 2004L is undergoing a degradation process that leads to aggressive deployment and potential rupture. However, the time in service of such inflators remains short compared to that of the inflators using propellant 2004. Further study is needed to assess the long-term safety of desiccated inflators using propellant 2004L.The Office of Defects Investigation is opening this investigation to examine whether a safety defect related to propellant degradation exists in non-recalled desiccated PSAN frontal inflators manufactured by Takata. This investigation will require extensive information on Takata production processes and surveys of inflators in the field. Lists of recall actions that may have used desiccated PSAN inflators as remedy parts, as well as the makes and models originally manufactured with them, is available with the downloadable version of this document (see -- note this information is subject to change/revision as the investigation proceeds). This investigation does not supersede EA15-001, which remains open.

What 2017 Ford Mustang owners say
Most recent owner complaints, unedited.
My 2017 Ford Mustang Convertible front door unlatched to the secondary safety position while driving at highway speeds. This became a huge issue on October 13, 2026 while taking a long-distance trip. The passenger door unlatched at least 10 times. During this trip, my car exceded the 150,000 mile limit to Ford customer satisfication program 21N10. When I contacted both my local dealer and the Ford customer service team, both said their is nothing they can do to help me. I am quite frustrated that Ford rejected my safety concerns on this known issue and was unwilling to recognize the extunuating circumstances of when this happened.
I have attached a complaint which sets for the odometer fraud resulting in severe damage to my engine. I have also attached mileage discrepancies and the documentation created and maintained by AutoNation Ford Valencia which records my odometer at 26,250 in September 2022 and after taking my vehicle in for service of the air condition, I received it back with an odometer reading of 25,134 which appear on the odometer. Please review my complaint and supporting documentation.
I have experienced a concerning issue twice while driving. On both occasions, I was traveling at approximately 72 mph with all doors closed and locked when the vehicle indicated that the passenger door was ajar. Although the door did not fully open, it appears that the latch may not have remained securely engaged. My concern is that if I have a passenger in the vehicle and this occurs again, it could create a serious safety risk. I would like to know what may be causing this issue and what can be done to correct it. Could this be related to a defective door latch, sensor, or another component?

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.
The contact owns a 2017 Ford Mustang. The contact stated that the driver's and passenger's side seat belts were seizing. The occupants were concerned about being stuck inside the vehicle. There were no warning lights illuminated. The mechanic removed the inside panels of the seat belts and greased and cleaned the parts.
