Selected complaints filed with NHTSA by 2015 Ford Focus owners, lightly cleaned up (personal details are redacted by NHTSA).
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. …
While driving vehicle on highway the Ford Focus started down shifting while accelerating. This caused the car to not be able to reach sufficient speeds on the road and could have caused an accident. With my family in the car I exited the highway and drove the vehicle home, with the car continuously down shifting and not being able to accelerate as designed. The transmission has known problems and model recalls. I brought it to the dealer for repair but the dealer would not honor the recall. I also called Ford customer care and they were of no help in covering this known issue.
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! …
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. …
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 made an initial post on 06/18/2026 so please reference that as well as this. I have not been able to drive the car since it died on me on the 18th of June. The car has been looked at a few times (actually stalling a third time while idling but was able to turn back on.) It has also displayed symptoms associated with the Ford Recall #26S40 / NHTSA recall #26V369 but it is listed at NOT included in the recall as of 07/06/2026. MIL is pulling Code P0420 (catalytic system efficiency below threshold) while only having 40k miles. It is also putting out an inaccurate fuel level for miles driven. The fuel tank itself is misshapen (concave bottom of the fuel tank). Again, reiterating here that it stopped twice while driving within 2 days on major PA highways/interstates and stalled for a third time while in idle mode as described earlier in this post. …
There were two times within a week where the car stopped in the middle of traffic. One was on Route 100 in a merge lane and the other was on the offramp of route 30 to 100 Exton. This happened in the middle left turn lane with traffic behind me causing me to need immediate police assistance to ensure my safety. The Check Engine light was popping from the TCM indicator which I was told I could still drive on without repairing it immediately. This came directly from Fred Beans Ford of West Chester PA. My car has been in the shop multiple times since December 2025 beginning with the original CPV recall and things got worse from there. It's caused lots of anxiety and ptsd while driving to the point I want to sell the car after it is repaired because I just don't feel safe anymore in it.
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.
1. Fluctuating fuel gage. 2. Car stopped while driving on highway multiple times. 3. Rough Idle and hard to start. DTC code P1450 is displayed. I went to the Ford dealership for 18S32 Recall and I was charged over $ 400 for recall to be performed. I did show them the Safety Recall Notice-18S32. There was not a crash but I went from Middle lane on GSP to right most lane and a nice lady slowed down to let me pull over to the shoulder. This could have been an accident. How can Ford dealership refuse to perform this recall and charge customers over $ 400? I will have to scan and upload the bill tomorrow.
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.
