2015 Ford Focus Electrical System Problems

I was getting ready to leave the grocery store and I crank up my car and I had a light come on stating that my car was overheating transmission turn off the car and as I tried to pull out of the parking lot, the car would barely accelerate it would barely go to mountain and it was stuttering up the heels I had to turn off the vehicle. Let it sit for five minutes to let it cool off and then I had to crank the car back up and then it started to drive again, but I did get a indication on my front dash stating that it was transmission

A major electrical issue has occurred in this car since June 1, 2025. The Traction Control System dashboard indicator (the skidding car) comes on even though I am not using the TCS. When this happens, I get a message saying "Hill start assist not available," and am unable to manipulate my headlights, use turn signals, or lock/unlock my doors (I need to use the physical key to lock/unlock the driver's side door). If this "Hill start assist" issue occurs and I turn off my car (or if it occurs when the car is off), then I am unable to start my car. I get a new message saying "No Key Detected," and the ignition does nothing. I have a physical key, and not a fob. If the TCS light goes away, then I am able to start up my car. However, this is unpredictable; there appears to be no way to force the TCS light to disappear, and sometimes it will stay on for over an hour with my key in the "on" position. As of late, it hasn't gone away at all, making the car unusable. This causes obvious safety issues when on the road, as I cannot use turn signals or change my lights as it gets darker or it begins to rain/snow. When not on the road, I cannot use my car at all. A dealer recently confirmed the problem with the Body Control Module, but was unable to fix it. They managed to turn the car on, but the problems returned after 24 hours. As I was driving home on July 18, 2025, the TCS light came on and suddenly I could not use turn signals or change my lights. I still had over an hour to drive home. I did arrive home safely, but have not been able to use my car since.

My transmission is always having problems with it. My check engine light will not turn after put over $5,000 into it.

1. MY car shuts off while driving and I don't understand why because my battery is new and all other components don't seem to be the issue i.e.: battery, starter, alternator. 2. My safety and the safety of my passengers were at risk because the car shuts off with no warning while driving. 3 I currently have the vehicle being inspected by my local Ford dealership but the problem has happened several times before taking the car to the dealership. 4. The problem is currently being inspected by the Ford dealership. 5. There were no warning's before the car shut off.

In August 2023 Focus would not accelerate smoothly while in traffic. Check engine light turned on. Vehicle would not go into reverse. Diagnostic scan negative with personal scanner. Took to transmission shop. Actuators replaced per diagnostic check $880. TCM ok. Slipping on acceleration continued with RPM to between 5-6 on acceleration. Took vehicle back to shop and actuators resynched with TCM. I received Ford Recall for defective TCM module dated September 2023. Ford evaluated by local Ford repair shop. Diagnostics performed. Recommendation was to replace clutch assembly $4100. Was charged $200 for diagnostics. Ford diagnostic report states: Description-U0073 Control module communication bus A off Failure type-88 Bus off Status-28 (Not current DTC) *Fault previously detected, not currently present* My concern with this info is if the fault was detected there is still fault! Am concerned that the faulty TCM and actuators caused issues with the clutch assembly and do not feel safe operating my 8 year old Ford due to skipping while accelerating in traffic. Vehicle one owner with 70,000 miles. No accidents and am young senior driver-age [XXX] . I can forward repair shop documentation. Thank you for your review and look forward to your recommendation.

The contact owns a 2015 Ford Focus. The contact stated that while his daughter was driving at an undisclosed speed, the vehicle stalled without warning. The contact’s daughter was unable to restart the vehicle. No warning lights was illuminated. The vehicle was towed to an independent mechanic where it was diagnosed that the body control module (BCM) software needed to be updated. The vehicle was not repaired. Additionally, the contact stated that while driving at undisclosed speeds, the vehicle intermittently decelerated while the accelerator pedal was depressed. No warning light was illuminated. An undisclosed dealer was notified of the failure and confirmed that the VIN was not under recall. The contact stated that upon research, the vehicle was included in the Customer Satisfaction Program: 14M02 for extended warranty coverage. The contact then referenced NHTSA Campaign Number: 15V436000 (Electrical System). The manufacturer was not notified of the failure due to the number being unreachable. The failure mileage was approximately 140,000.

Radio and speakers have not worked for over a year- making loud popping and screeching sounds. Automotive center #1 stated it was a computer system fail and they could not fix it because they did not have the proper software. Then I went to get a new fuse for the cigarette lighter and was told something is leaking. Took it to Firestone automotive center to be told nothing is leaking and I should go to Ford because it is most likely a sensor issue. Car says it is overheating when it is in idle. And no one I go to seems to care to help me get things fix. Ford can't help for 2 weeks due to availability. This has been the worst experience with a car I have encountered with trying to figure out the problem.

When driving my car the first day I bought it, the wrench icon illuminated, telling me to check the manual. I figured I would do so after work, but as I tried to start the car to leave work, I received a "Stop Safely Now" message and could not start the car. It had at least 30% charge, being electric, so that had nothing to do with it not starting. I am glad this did not happen when I was driving, as I have seen other instances of earlier years of the Ford Focus electric with this same issue. In other cases, it came in while the owner was driving, causing all power to the accelerator to stop. It was recently serviced since I just bought it, so I know there shouldn't have been any outlying service to be done. I am calling a tow service in the morning to have it taken to a dealer, so hopefully they can figure out the issue. I just wanted to let others know that this item that has had a recall on earlier years still persists with the 2015 model.

Ford Focus 2015 w Select Shift. The warranty is in effect for 10 yr 100,000 drivetrain. TCM - AE8Z7Z369F The car began sputtering in the middle of August when pressing on the gas. The car would jump when hitting about 12-15 mph and again at 28-35 mph. At this point the engine light was on I took the car to a local certified auto shop where it was diagnosed that the TCM module was having problems and I would need to take it to a dealership. Late august I took it to the Beacon Healey Ford Dealership to get it fixed and they confirmed it was the TCM and that it could be a few weeks because the part was on backorder. I called every few weeks and it has been the same status since then. Luckily this part and the labor will be covered under warranty but this has left me in a very difficult situation that the dealership or ford are not doing much to help with. I was not offered a loaner/rental car and have been using a relative's car which they will be needing back soon. It has been 3 months and they still do not have a loaner for me or any updates at all on an estimated time for resolution or when the part will at least become available.

Radio is making a loud popping noise at random times. It’s easily distracting and could very possibly cause an accident due to the random loudness of the popping.

Vehicle stalls & shuts off during use with zero warning, both while in park and while car is running and stopped with foot on brake at a stoplight, and also seems sluggish and straining during active driving as if it wants to stall and shut down. When car stalls, a warning displays (System Start Fault) when attempt is made to restart vehicle and the vehicle WILL NOT restart for anywhere between 45 minutes to 4 hours (so far). The vehicle will then go through varied reactions to attempts to restart when ignition key is turned ... ranging from the dashboard warning of System Start Fault with no success at restart to absolutely NO response of dashboard or other lights/warnings/electrical (completely dead). When this stall/complete shut down occurs, it also becomes locked in whatever gear it was in (Park or Drive) when the stall & immediate shutdown occurs and the gearshift locks in place and you're unable to shift into park or neutral as needed for tow or to move the vehicle off the roadway without the tow driver or other person dismantling the area covering the gearshift to access the hidden pin to shift into neutral to move the vehicle from the roadway. After the first complete shutdown during use occurred, it was taken to a local Ford dealership who was "unable to find the cause" at that time. Since that time, this complete shutdown while in use has occurred another four times within the 3 months following, resulting in either towing the vehicle or waiting 1-4 hours where the vehicle stalls/dies (parking lot, stoplight, etc) until the vehicle decides to restart. I have become terrified of driving this only means of transportation as I don't know when or where this vehicle is going to shut down without warning and fear I will be struck and killed by another vehicle or someone else killed when it shuts down again on the active roadway.

I was driving down the highway and my door locking latch and cable failed. The door came open going 75 MPH.The defective dealership part I found out is the subject of recalls on other Ford Focus year models but my model was left off the recall. This is a huge safety concern as my door is unable to lock at all times including highway driving.

My car shut off randomly in the middle of lane and on the highway too. My car show "system fault". Didn't start until I put a new battery. The next day it happened again it show again "system fault". So I change a wire sensor that connects to the battery. It work then while you are driving it stop or when you are parked too. I really don't want to drive I'm afraid I get into a accident while on the road.

WHILE DRIVING MY CAR THE CENTER DISPLAY WHICH HAS MY ODOMETER AND DIGITAL SPEED AS WELL AS ANY WARNINGS FOR MY CAR SHOWED LINES ACROSS IT AND IT IS DIFFICULT TO READ. IN RESEARCHING IT I FOUND THIS IS A COMMON OCCURRENCE WITH THESE CARS AND IT WILL EVENTUALLY GO COMPLETELY BLACK AND NOT WORK AT ALL.

AFTER DRIVING THE VEHICLE AND PARKING, AFTER PUTTING IT IN NEUTRAL WITH THE E BREAK ON AND PRESSING THE ENGINE START STOP BUTTON TO TURN IT OFF, THE ENGINE SHUTS OFF BUT THE DISPLAY ON THE RADIO AFTER SITTING IN IT FOR A WHILE SAYS "TURN OFF IGNITION SAVING POWER" OR IF I GO TO GET IN THE CAR THE NEXT DAY IT SOUNDS LIKE IT'S DEAD THEN STARTS WITH EVERYTHING RESET

WAS DRIVING DOWN HIGHWAY AT 60 MPH. VEHICLE STALLED. PULLED TO SIDE OF ROAD. RESTORED CAR. GOT OFF THE HIGHWAY AND WHILE DRIVING CAR STALLED AGAIN. RESTARTED PULLED TO SIDE ROAD AND WHILE DRIVING STALLED AGAIN. *TR

EVERY 4 DAYS THE STEREO DROPS THE BLUETOOTH CONNECTION. THOUGHT MAYBE IT NEEDED A SOFTWARE UPDATE. THEN I NOTICED MY MPG WAS ONLY AT 13.3MPG WHILE HIGHWAY DRIVING. FURTHER INVESTIGATION I NOTICED MY DISTANCE TO E WOULD SOMETIMES READ 415 MILES AFTER FILLING UP THEN IT WOULD SAY 226 OR EVEN 183. AM I MISSING SOMETHING HERE? CONTACTED A COUPLE OF FORD DEALERSHIPS BECAUSE MY WARRANTY & EXTENDED WARRANTY EXPIRED ( MIND YOU THE VEHICLE IS ONLY 5 YEARS OLD) STARTING TO HAVE ELECTRICAL ISSUES AND FORD WANTS TO CHARGE ME TO EVEN LOOK AT IT. IF I AM WRONG PLEASE SOMEONE EDUCATE ME. ALSO RESETTING THE SYNC SYSTEM HELPS WITH THE BLUETOOTH PROBLEM BUT I ALSO HAVE TO DISCONNECT THE BATTERY FOR 30 SECONDS. *TR

I LITERALLY JUST BOUGHT THE CAR WITH THE SHUDDERING WHEN COMING OFF OF A COMPLETE STOP AND WAS TOLD IT WAS MY TIRES. I HAVE GOTTEN ALL NEW TIRES AND IT IS THE SAME PROBLEM NOT SOLVED. THEN MY CAR STARTED TO HAVE A BIGGER PROBLEM WITH THE RADIO ONE DAY OUT OF NO WHERE MY SPEAKERS STARTED TO BE STATICKY. THE NEXT DAY IT WAS STATIC AND VERY LOUD POPPING NOISE ALMOST MAKING ME GET INTO AN ACCIDENT ON THE HIGHWAY BECAUSE IT IS SO LOUD. I HAVE TO PULL OVER EVERY 10 MINUTES AND SHUT THE CAR OFF WITH MOST OF THE TIME THE NOISE STILL GOING WITH THE CAR OFF. NOW I CANNOT SEE ANYTHING ON MY RADIO SCREEN OTHER THAN THE DATE AND TIME WITH A BLACK SCREEN. I HAVE THE RADIO AND SCREEN OFF AND THIS LOUD POPPING / STATIC NOISE IS UNSAFE TILL THIS DAY. DUE TO THE PROBLEM I CANNOT DRIVE MY CAR ANYMORE. THERE HAS BEEN MANY COMPLAINTS ONLINE AND IN PERSON ABOUT IT BUT NOTHING IS DONE. *TR

THE RADIO QUIT WORKING BUT MORE IMPORTANTLY IT MAKES INTERMITTENT POPPING NOISE SO LOUD IT HURTS YOUR EARS. IT EVEN DOES IT WITH NO KEYS IN THE IGNITION. AFTER INTERNET RESEARCH THIS HAS BEEN HAPPENING IN MODELS SINCE 2012, MINE IS A 2015. IT IS MY DAUGHTERS CAR AND SHE IS SCARED TO DRIVE IT BECAUSE IT'S SO LOUD IT STARTLES HER WHILE DRIVING. HAPPENS ALL THE TIME, STATIONARY, DRIVING, NO KEYS IN IGNITION AND RADIO WILL STILL WORK SOMETIMES WITH WHITE NOISE BUT THE POPPING SOUNDS LIKE IT IS FULL VOLUME. IT IS VERY STARTING AND SCARES ME ALSO.

WIND SHIELD WIPERS MALFUNCTION AFTER 15 TO 30 MINS THEY RAPIDLY SPEED TO AND YOU ARE NOT ABLE TO CONTROL MODULE. THEN WIPERS SLOW DOWN AND TURN OFF AND ARE UNABLE TO COME BACK ON. ALSO WHEN YOU TURN VEHICLE OFF WINDSHIELD WIPERS STAY ON.
