Engine 2

Brought the car in for service. The tech called me back and said the engine was blown. Condensation in cylinder 3. This was due to the cylinder walls being engineered to small. Which caused a leak in the coolant jacket. I paid out of pocket nearly $10,000 to have it replaced because the third party warranty that I had purchased declined my coverage to fix it because it’s a known issue by ford. Bc

This complaint is a formal notification of a Recall Remedy Failure regarding NHTSA Campaign 22V082000 / 25V572000 (Rearview Camera Wiring Harness / Camera Replacement). My vehicle was brought to an authorized Ford dealership on 07/22/2026 to complete the recall remedy. Following the service, the backup camera functionality has completely degraded and is now worse than before the service. The screen is consistently displaying entirely black / distorted screen / Message Camera not available, presenting an ongoing, unmitigated back-over safety hazard. The manufacturer's remedy has failed to resolve the safety defect. Returned to the authorized Ford dealership on 08/21/2026 and was told this is a known issue and there is another "recall" fix for this issue, but parts are now available at this time. I need to follow up in a month or more.

Nelson v. Ford Motor Company is a class action lawsuit targeting a defect in Ford's 2.3-liter EcoBoost engines. The suit highlights coolant leaks into engine cylinders, overheating, and catastrophic engine failures. I have had my 2016 ford mustang ecoboost in and out of mechanic shops for months now accumulating well over $7K in out of pocket expenses. I have been to multiple mechanics trying to diagnose and fix the problem but in the end it was a design flaw in the 2016 ford mustang ecoboost 4 cylinder which caused it to leak coolant, misfire, and overheat. I have been having this problem for some time now, this put my safety and the safety of others at risk because I had to slow down dramatically in order to pull over on the freeway due to the engine overheating from coolant loss. I've also experienced problems like trouble starting, rough idling, loss of coolant, and huge clouds of white smoke coming from the exhaust upon start. I have saved every single receipt and invoice breakdown since this problem began. My mechanic has also been documenting everything including taking notes and photographs of every issue. My car is currently in the shop right now being worked on. My mechanic says that he can temporarily patch the problem with a high performance head stud, copper sealant, and an ExtremeHeat metallic repair paste by JB Weld to momentarily solve the issue. He says that he does not know how long this patch will last so he is insisting I either get a new car or to see what my options are regarding the class action lawsuit filed against Ford.

The passenger side door is periodically opening to the first catch while driving on the highway without anyone touching the handle and it does not matter that the door is locked. It is very scary for any passenger when it happens. For the driver the tendency is to try to reach over and re-close the door at highway speed which seems dangerous.

The rear view camera has a recall. I took the vehicle into a Ford dealership on 6/23/26 for this recall. This is a risk to myself and others because backup cameras are a federally required safety feature. This is my 2nd attempt for Ford to fix this recall at two separate dealerships. Ford does not care about their recalls and the safety of Ford customers! I almost hit another car that was coming out due to the blind spots on that vehicle. My young daughter also drives the car and this is not the 1970’s as young drivers depend on that feature. Ford said that they could not find the problem with this issue and further diagnosing must be done on my part for $198. This is not fair to customers as this was a recall issue. If Ford is not properly training their technicians to diagnose this issue, it should not be the responsibility of the customer to pay for their error in producing this car. The problem has been reproduced and confirmed by a Ford dealership. There were no warning lights or issues that were displayed. Ford only sent out letters stating that a recall was issued on the problem. In May of 2026 my backup camera and trunk was not working. Ford inspected and replaced the parts on the vehicle that they assumed was part of the recall. For a 2016 Mustang, a common cause is not just the camera itself but also wiring/connectors in the trunk area or the APIM/radio module that displays the image. If the dealer simply performed the recall software update or replaced one component and the screen is still blank, the underlying problem may not have been fully diagnosed. This the 2nd attempt to have a recall fixed by Ford but to no avail (2 separate dealerships)

There are two recalls on this vehicle. South Bay Ford, located just a few miles farther away than Auto Nation Ford in Torrance has no problem with pick up and delivery resources to insure recall work is completed but stated I must use Auto Nation Torrance Ford because I fall into their service area, yet Auto Nation Ford Service Manager contacted on 6/22/2026 @ ~ 4:05 P.S,T. stated they do not have enough people to perform pick and delivery. It would seem to me Auto Nation Ford in Torrance has chosen profits over recall compliance putting lives at risk. I thought this was important enough for you to look into.

Manufacturer has failed or is unable to remedy this safety recall for your vehicle IN A TIMELY MANNER. The Recall was from September 16, 2025. It has now been OVER half a year with NO remedy. I live in a salty air state and the last thing I want to happen is to drive with a seat belt with reduced effectiveness. I've ALREADY been in an accident a decade ago where a woman T-Boned me. I had a 2001 Mustang Convertible at the time with the convertible down. It's just like this Mustang with the recall but older. Thankfully the airbags and seat belt worked. Something needs to be done asap !!!!

They have a recall for the seatbelt so I got my car inspected and tested and my seatbelts are fine. I use this as a rental car and my business is stopped and I’m losing money every day that I cannot rent this out.

The steering wheel over time is very loose and in my case i need to be very careful with it because I feel I am losing control on my car while driving. You can feel the steering wheel moving up and down without little to know force also while driving. I don't even drive that fast since my way to work is always in a school zones.

The vehicle was returned to the dealer, and it was determined that the camera did not need to be replaced. The vehicle was not repaired under NHTSA Campaign Number: 25V572000 (Back Over Prevention); and the failure persisted. The manufacturer was made aware of the issue and referred the contact back to the dealer for assistance. The failure mileage was unknown.

There have been 3 instances within the last year and a half where the rear window of my vehicle (Ford mustang) and the rear window of family member ford mustang both have shattered during the extreme cold possibly due to the heating coils on the window over heating and burning. You can see a burn pattern in the window This is a safety issue due to the window shattering, it sounded as if someone shot my window out the first time it happened my [XXX] son was in the back of the vehicle and I was driving home. The second instance, same vehicle, started the car using the remote starter and it did the same thing. This has not been inspected by my insurance representative, it has been reported in both instances through my insurance and pictures have been taken. There have been no warning signs or even issues, there wiring look like it had been burned, melted INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

At about 75k miles my mustang started misfiring at about 2,500 rpm’s and higher. Turns out it was a blown head gasket. This engine model is prone to what happened to it. Ford should have a recall for these engine and a solution as they’re ticking time bombs. I wish I could drive with the peace of mind of not worrying about it. I couldn’t drive my car for months because of the warranty not even wanting to cover it. The warranty from the used car dealership. Got unlucky.
