The vehicle and video footage of the failure are available for inspection upon request. Timeline of events January 13, 2026 – the vehicle displayed a “stop safely now” warning message and lost the ability to accelerate. The vehicle had to be towed to lehighton Ford. January 21, 2026 – paid $866. 85 for repairs including battery service, rear control module replacement, and pcm harness repair. Lehighton Ford stated the vehicle was repaired and safe to drive. Within minutes of leaving the dealership, the vehicle stalled again in active traffic and had to be returned. The issue was escalated to the Ford engineering hotline and a field service engineer.

I took it to the Ford dealership and they diagnosed it as having a parasitic draw from the 12 v battery when the car is shut down so when you go to get into the car if the battery is dead, they will fix it for $425 however, this problem was a recall in 2013 and my car did have a recall done to it. However, the issue is still going on therefore I feel as though the customer should not be charged. My car broke down going up the canyon and it told me to pull over safely, which I did going up the hill, but it was on an exit and it was a dangerous situation as I could not even turn on my flashers. This has been a known issue with the Ford c max since 2013 and since their software program then did not correct the problem and now they want to update the software why should the cost come from the consumer?.

I am filing a formal safety complaint regarding NHTSA recall 25v695 / Ford recall 25s49 on my 2015 Ford C-max (VIN: 1fad*************). Ford motor company’s recall notice dated October 2025 states that the rearview backup camera may display a blank or distorted image, increasing the risk of a crash. Ford further confirms that parts are not available and that there is no estimated timeline for repair. Due to this acknowledged safety defect, my vehicle was removed from service on October 14, 2025 following a rearview camera inspection. I rely on this vehicle for income-producing transportation services. Prior to removal from service, my vehicle generated $1,221 over 42 days, resulting in a documented daily average of $29. 07 per day. As of today, the vehicle has been unavailable for 71 days, resulting in a verified loss of income totaling $2,063. 97, which continues to increase by $29. 07 per day. I received the official recall letter on November 7, 2025, yet Ford has provided: no repair parts no estimated repair date no interim remedy no loaner or rental assistance despite multiple contacts with Ford and the department of transportation vehicle safety hotline, there is still no remedy. I am requesting that NHTSA review the effectiveness of this recall and Ford’s failure to provide a timely remedy for an acknowledged safety defect that is causing ongoing financial harm.

Nhtsa complaint update / addendum I am submitting this update to my existing complaint regarding safety recall 25s49 (NHTSA recall no. 25v695) for my 2015 Ford C-max hybrid (VIN: 1fadp5bu0fl116791). Ford motor company has now formally stated, in writing through the south carolina department of consumer affairs, that: • the rearview camera defect may cause a blank or distorted image while in reverse • the condition increases crash risk • parts are not currently available in sufficient quantities • no repair will be available until q2 2026 or later • no loaner vehicle or rental reimbursement is authorized • owners are expected to continue operating affected vehicles indefinitely due to this recall and lack of remedy, my vehicle was removed from service on October 14, 2025. As of December 29, 2025, the vehicle has been unusable for 76 days, resulting in $2,209. 32 in documented lost income based on historical earnings of $29. 07 per day. Ford has acknowledged the safety defect but is offering no interim solution while delaying the repair for potentially over six months. I am concerned this creates an unreasonable safety and economic burden on affected owners and may represent a broader issue impacting many consumers. I am requesting that NHTSA review Ford’s prolonged delay, lack of interim remedy, and refusal to provide alternative transportation while a known safety defect remains unresolved.

While driving the dashboard instrument panel beeps and flashes the word "put in park" and "stop safely now", and the speedometer stops working, all kinds of warning lights start flashing on and off on the instrument panel, the heater goes on and off on it's own, then the instrument panel goes black, speedometer shows zero and car goes into shutdown mode. I was put in risk while driving without a speedometer and other vehicles near me were put into risk; when I pull over and stop the vehicle it strands me and I need a tow. This has happened randomly many times; I took it to Ford for repair, they didn't know how to fix the problem, my car was at Ford for 6 weeks! and I was without a car all that time, now 3 months later it's doing the same thing! I have videos of it happening along with the pictures I'm posting here, it is very scary when it's happening while driving and it's scary being stranded in unsafe places having to wait for a tow. This issue is unresolved and dangerous, I need Ford to get more involved.

Ford 2015 cmax energi with 41,000 miles. I was driving on a 2 lane highway coming to a stoplight and had to press the brakes firmly to avoid an accident at which time my 2015 cmax energi abruptly stopped w a growling noise,. The dashboard lit up like christmas. I observed the abs system/abs module failure/malfunctioned lights. 2015 c max energi was available for inspection when I brought it to the dealership and verified it was abs module that had malfunctioned. I was told by the dealership for my safety and others not to drive the car. Sawgrass Ford retained my car for repairs. Sawgrass Ford as well as family and friends stated that my safety and the safety of others were at risk because of the obvious reliability of brake failure. Brake failure could lead to death to me and anyone else on the roads/highway. The problem has been reproduced and confirmed by the dealer@ sawgrass Ford sunrise florida. The vehicle and the component has been inspected by the dealership because it was repaired once the part , which took about 2 1/2 months due to parts being backorder from Ford corporation. Ford has many previous abs module recalls on several of their models, but the cmax energi isn’t due to it not being a popular car. I’ve researched through the internet and forums and found that this is a common problem for the cmax energi. I retained the damaged parts and have them enclosed w photo of damaged parts and the box that contained the new parts. Additionally, when the brakes were applied the car lurch and jerked, and additionally, there was the “smelling of electrical burning “ bright red warning lights. Aaa was called an immediately was towed to the dealership around mid November. Dealership got in touch with me November 23 and ordered the part fv672c219. At that time I was told that the part would not be available and it was on backorder. Ford corporation 800-392-3673 and confirmed b/o.

The contact owns a 2013 Ford C-max hybrid. The contact stated while driving on three occasions at approximately 30-55 mph, several unknown warning lights were flashing. The message to shift to park(p) was flashing. The vehicle was shifted to park, and the vehicle stalled and failed to restart. The contact's husband assisted with restarting the vehicle. The contact determined that the battery was working as designed. The vehicle was taken to the local dealer for five weeks, where it was diagnosed that the battery junction box had corrosion and defective fuses. Additionally, there was a failing control unit. The dealer informed the contact a Ford engineer was advising with the repairs. The vehicle was repaired. The manufacturer was not contacted. The failure mileage was approximately 70,000.

My stereo/navigation console went out, just went black and stopped working. I bought it to my local garage and they said it was a costly repair and that there is a recall/service bulletin on it and that I should take it to a Ford dealer. I did and they acknowledged the issue but said my VIN wasn't covered, but it was a known issue with C-max of this year. So I didnt have the car services. A few months later, (2 weeks ago) my battery died and could not be jumped, so I had it towed to my Ford dealer. He informed me that the potential cause of the battery damage was a short in the console/radio/nav/screen system. I agreed to go forward with the costly repair. . . They have so far not been able to resolve the issues. This morning I called Ford and explained the issue. They said since there is not a recall associated with my VIN, there was nothing they could do. I asked them to look up the "issue" not the VIN and they acknowledged that there are issues with 2013 C-max energi models associated with the console. I asked for a bulletin number and was given 202363. I believe the recall is associated with the Ford parts and so my VIN number may not be registered or something to that effect. I'm not sure how to look up the number they provided. While I dont think that not having a radio or nav system is a safety issue. The fact that it has caused the car to completely shut down and standing us is an issue. Again, Ford is aware that this type of issue exists, for this model, for this manufacturing year. They say they will only cover the repair if your agency tells them to, ugh thank you, [xxx] [xxx] [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Recall number18s24 my car had 3 recalls so I contacted the legacy Ford dealer in mcdonough on [xxx] and made an appointment on [xxx]. When we brought the car, dealer didn't fix the recall above saying they didn't have parts even though we made an appointment over 2 months before. They told us they will let us know when they gets the parts, but it's been over 2 weeks and they don't contact us or respond any of our email. And since we brought our car to dealer, the car stop charging from charging cord. They said they didn't do anything about that and if we want diagnostic, they will charge for $150. I just wanted to fix all of the recall so I bought the car but feel like I just brought it to break my car. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I have a 2016 Ford C-max. On Saturday, 9-16-2023 my wife and I were traveling on highway 69 in prescott az. We turned off the highway and about 50 yards from hwy 69 a stop safely now flashed on the instrument pannel. The car immediately braked hard and stopped. I had no time to pull over. Had it been 50 yards sooner I would have abruptly stopped on hwy 69. The hwy was traveling at 55 mph. You figure it out, we were going to have an accident 100%. The C-max was towed to sun valley tire, a aaa approved repair shop in prescott valley. They pulled up the Ford, technical service bullitin - TSB 17-0015. That bullitin describes wiring that chaffes and shorts out the car. Exactly what happened to us. The actual fix is simple, locate the shorted out wire and repair it. To get to it requires disassembling most of the car. Total cost $438. 01. That is not the point, Ford knew that this problem exhisted, sent out a TSB and is allowing Ford owners like me to have a life threatening insident. Why has Ford been allowed to continue allow these C-max's to stay on the road witout a fix! are you doing your jobs? I want the NHTSA to do it's job. I also want to be reimbursed. Who do I contact. You have my VIN # and therefore all my information.

Several times over the past 3 years, the 12 volt battery has been deeply drained while the car has been off/unused for ~3 days. (the problem has been described on your website: https://static. Nhtsa. Gov/odi/tsbs/2016/sb-10093862-2532. Pdf. ) this is a safety issue because there is a reasonable expectation of serviceability of a car, for emergencies or for returning to a safe place. Just as one depends on the reasonable reliability of devices like fire extinguishers, elevators, heart monitors, etc. , so does one expect cars to be reasonably reliable. There is no advance warning that the battery will be drained.

Steering locks to the point that it can't turn. Happened while driving. Unknown cause. Warning light came on for driver to park. Issue unresolved and can no longer drive car.

The contact owns a 2014 Ford C-max. The contact stated that the rear liftgate was opening independently. The contact stated that upon investigating the failure, he noticed that the failure was related to the original key fob of the vehicle. The contact stated that the key fob button that engaged the liftgate was two times press button; however, the key fob would engage the liftgate unintendedly when the key fob button was in contact with any object or surface. There was no warning light illuminated. The contact was concerned that the failure could occur while driving. The dealer and the manufacturer were not notified of the failure. The vehicle was not diagnosed or repaired. The failure mileage was approximately 78,000.

My vehicle fails to properly turn off after it has been put into park. As a result, I believe the regular battery is being drained at an alarming rate. If my vehicle sits overnight 8-10 hours, it is very likely that the battery will be dead and the car doors will not open. At first I thought it was just a manufacturer error with the batteries, but once I had purchased three batteries in less than 6 months. At this point, it seems to be an electrical draw issue that I am uncertain how to resolve as these cars are barely 10 years old.

What component or system failed or malfunctioned, and is it available for inspection upon request? I have a 2013 Ford C-max se that is having terrible white noise and static from the speakers. I see that this is common with the sync system and not limited to C-max models how was your safety or the safety of others put at risk? I have not had a diagnostic run but I have seen so many listservs with the speaker issue. The car will be quiet and then blast static to the point of having to pull over to get the car over to get it to stop. It's so loud sometimes that it is hard to drive. Has the problem been reproduced or confirmed by a dealer or independent service center? I am taking the car in on November 10th for an inspection. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? I am taking the car in on November 10th for an inspection. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? no, this has gradually be increasing in severity over the last few months.

Lift gate opens randomly when vehicle is off.

While driving, the cmax displayed a red hazard, stop safely now, and lost all propulsion. The car was unable to be moved and is stranded in the driving lane.

120 v0lt charger overheated now the unit will not charge the car same as the recalled units on 2013, 2014, 2015 my unit is a 2015 and local dealer says it is not covered why is this.

Rear back-up camera does not display on dashboard console screen when air temperature is cold, I. E. Below about 45º, and will only turn back on when the car has sufficiently warmed up after driving some distance. This has been happening for at least two years. When the camera is not working, there is a blind spot directly behind the car. The rear of the car proximity warning signal still works, but the screen remains black. I brought this problem to the attention of the dealership service manager, who told me he could not find anything obviously wrong.

The vehicle was entered while parked and locked with the security system active. A panel was removed from the lower left side of the housing beneath the steering wheel. All four windows had been lowered to the maximum extent possible, apparently without breaking them. Debris was strewn across front and rear seats. Spare floor mats stored in the trunk/hatch area (normally out of view due to a cover over the hatch and the rear seat backs) were deposited on the rear seat.

Vehicle finished charging, and then was unplugged. Vehicle's warning system says vehicle was still plugged in and and wouldn't move. Vehicle was towed into dealership and diagnosed charging port needed to be replaced. Charging port is unattainable and vehicle sits at dealership with no light at the end of the tunnel. Charging port unattainable, tells me Ford has a serious problem with this issue.

Car will stall and brakes and steering lock up. This has occurred in when pulling into traffic. It always occurs when on a hill. Very dangerous but Ford denies any problems. It has occurred since 2014. Last time was as below.

The contact owns a 2013 Ford C-max hybrid. The contact stated that on several occasions, the vehicle failed to start up or unlock due to a defective battery.

Driving along a highway holding steady speed of 65mph, the car displayed a "stop safely now" message and disabled the accelerator. We were able to coast to a stop on the side of the road. The car would turn on and off with the push of the on/off button, but the "stop safely now" message remained on the dashboard any time the car was powered on, and the car would not move. We called Ford as we are still under warranty; however, a tow truck would have taken approx 90 minutes, and I was not in a safe position, so I used a obdii scanner and app to reset the fault codes. After that the vehicle resumed normal operation. This is the third time we have seen this error in the last 18 months; however, the last time was approximately a year ago.

Warning light with an engine and wrench appeared for 24 hours. Wrench disappeared and then the engine. Dealer insisted the car fixed it self and later claimed their tester show no problem. Dealer was using a generic tester which is not designed for high voltage battery system. �hybrid/ev battery balancing circuit stuck� reflected on a personal newer model engine tester. This battery is warranted for 100,000 miles. Dealer not using the correct type of engine tester based on the type of battery.

When parking or stoping, turning the key off, removing the key the engine will keep running. This was reported to Ford under warranties. This is easy to catch in a closed garage but impossible to detect outside (no noise when walking away from car) 6 times in the last 3 years.
