2012 Ford Focus electrical problems

ELECTRICAL SYSTEM

Beginning in approximately May 2025, the vehicle began displaying diagnostic trouble codes identified by independent auto parts retailers and service providers. These codes indicated potential issues within the engine, electrical, and powertrain systems. The vehicle was subsequently brought to a dealership for diagnostic evaluation and remained there from approximately May 15 through May 19, 2025. During this time, the dealership reported that no diagnostic codes were present and did not resolve the reported issue. However, the vehicle had recently exhibited repeatable symptoms, including entering “limp mode” and triggering diagnostic trouble codes, prior to being delivered to the dealership. Similar codes and issues were again identified after the dealership visit. The vehicle has experienced multiple incidents of entering “limp mode,” resulting in sudden loss of power and reduced drivability while in operation. This condition occurred without reliable warning and created unsafe driving situations, including the inability to maintain normal traffic flow. Due to safety concerns, the vehicle has not been driven under normal conditions since approximately May 2025 and has been limited to short, local movements only. The issue poses a safety risk to the driver, passengers, and surrounding traffic due to unexpected loss of power and inconsistent system diagnostics. The problem appears to be ongoing and unresolved. Independent diagnostic records and service visit documentation are available upon request.

ELECTRICAL SYSTEM

I own a 2012 Ford Focus with approximately 51,000 miles. The transmission warning light came on, and I was informed by a repair shop that the transmission control module (TCM) and gears need repair. This vehicle uses the PowerShift dual-clutch transmission (DPS6), which has been the subject of a class-action lawsuit and multiple extended warranties due to widespread failures. The car exhibits jerking, delayed acceleration, and loss of power, which create dangerous driving conditions, particularly when merging into traffic or crossing intersections. Ford informed me I am outside the warranty period and refused to assist, despite this being a well-documented, recurring safety issue for which they have admitted fault in other cases. I am reporting this issue because it poses a serious safety hazard, and I believe the TCM defect should be subject to a mandatory recall. Ford is shifting the burden of a known manufacturing defect onto consumers, and this needs to be addressed before someone is injured.

NHTSA complaint #11594231 — an unverified report by a vehicle owner.

ELECTRICAL SYSTEM

While driving on interstate ,my car suddenly started hesitating and failed to pick up speed. The engine light came on. I pulled over, but did not turn car off fearing it would not restart, to look at owners manual. The problem continued as I drove home. I have driven it once for a short distance since and there was no change. This could cause an accident since it happened unexpectedly while driving at high speed. Brake light fault warning light is illuminated although light appears to be working. This could cause rear end collision if not operating. Luggage compartment opens while driving which causes visibility issue and chance of items stored there to blow out and cause accident. I can not tell if this issue is included in recall addressing locks and latches. Driver side window no longer operates, preventing escape if needed

ELECTRICAL SYSTEM

I have reported before my vehicle is and has been cyber attacked. This time around my horn has been disable. They turn on the radio, they turn on the light lights of the vehicle, they turn on the radio, they turn on the ac/heat control. If I take it in again, they are going to tell me nothing is wrong. This is very dangerous for me as a driver. I cannot drive a vehicle without a horn. I NEVER heard from you guys on the last report I made. Not sure how this one is going to help. This Ford vehicle is dangerous! If you can please assist, I would appreciate it. Thank you!

ELECTRICAL SYSTEM

My vehicle is under a cyber attack! I went to Ford dealership to have my horn fixed and explained the same thing I am about to tell you. They check and stated that there were some issue with the Sync system but all is well. If I further issues to see them again. Well, I have the same issues. My horn is not working when I know I just had it fixed! I was driving when suddenly my vehicle engine felt as though it was going to be disabled. The check tire pressure comes on and I have fairly new tires on my vehicle not to mention I had them checked prior the circuit board tells me. Folks know about the lighting of the vehicle that transmit looking for a signal when you open the trunk or open the doors. There was nothing wrong with this care when purchased used. I also believe due to the bluetooth signal, folks can hear my conversation and I DON'T HAVE A PHONE OPERATING WITH THE VEHICLE. When using phones in the car though, it automatically somehow enable the bluetooth on when I have it set to off. Another vehicle can ride behind me with his lights blurred onto my vehicle and go to the app of his phone and disable something in my car. Once my radio was changed and i did nothing to it. Sometimes it is set to a different radio genre station that I don't listen to. A truck road behind me and literally cut my radio on and could not turn it off until I pulled over and shut the car off! I have reported this to the police but folks think I am out of my mind. My life has been a living hell because I work for the state and folks there are doing the same thing to my car as a stranger would do when driving behind me. Also the car can pick up bank information if you are using the drive thru. They can track your account. I believe folks at work and neighbors of mind are using an app to do so. Because the car can connect to a garage , it can pick up a signal that can transfer to another vehicle if they have their car on. Again, the lights are the signal transmitter picking up information

August 3, 2023, vehicle bucking from 1RPM to 2 RPM. No engine lights came on. At every stop and go vehicle hesitated. I was driving a relative to a post operation doctor visit. Went to dealer following day. They could not inspect the car. Gave appointment for 5 days later. Recall letter I received is for the TCM/PCM-Transmission/Power Control Module. Dealer says they have vehicles waiting 2 and 3 years for this part. If this is my issue they cannot provide me with a time frame for getting the issue corrected. When I drove to the dealer the engine light did come on and it continues to be on. Car can leave me stranded or vehicle may jerk forward even with the brake applied are some of the different issues that can happen.

Failure of the TCM

NHTSA complaint #11482243 — an unverified report by a vehicle owner.

ELECTRICAL SYSTEM

The vehicle needs PCM and TCM replacement. Stalls while braking or apply pressure to gas peddle while driving, faulty gear changing mechanism has issues switching to proper gear due to the underlying problems above. It has turned off while driving on the interstate without warning. May instantly stop while applying minor pressure to brakes. Has been inspected by mechanic and AutoZone employees confirming the issues. It is unsafe due to the instant stopping or applying to breaks behind another driver almost hitting them or causing someone to hit from behind. Furthermore, inaccurate gear changing causes an increase rapidly in speed or very slow in speed which could lead to accidents.

ELECTRICAL SYSTEM

The power steering has gone out again. We replace the rack and pinion with a brand new one and it still went out again. There are many complaints in regards to the power steering going out, including a death due to this car. There have been recalls for other Ford’s that were forced to be recalled because Ford continued to ignore the issue. Even with those recalls, my focus is not included and it a huge safety issue and decreases the drivability.

ELECTRICAL SYSTEM

I had regular service done on my vehicle 5/27/2022 to which the battery needed to be replaced. That was done without issue however 3 days later as I was on my way to work the check engine light came on and my engine began revving then stalling/losing power as well as shuddering. This was especially concerning as I was on the highway traveling at 70 MPH when suddenly I lost engine power and my vehicle began lurching. I was close enough to home that I was able to turn back and drive very slowly as it was apparent there was an issue in the gears turning over when accelerating. I could not get my vehicle in for service as the dealership could only schedule me later the following week to get it diagnosed. I was able to drive it, again very, very slowly - to the dealership. I was told it was the TCM; 14MO2 Extended Coverage Warranty. The dealership assured me this would be covered yet now continues to tell me that this is not being accepted and that I have to pay out of pocket for this repair. I'm unsure of what to do at this point as my daily commuter has been at the dealership since June 9th 2022.

ELECTRICAL SYSTEM

A couple weeks ago leaving work a warning light came on that the power steering assist was disabled/malfunctioning, to have it serviced. It became prohibitively difficult to steer my car. I called AAA and had it towed to an independent service center. They reported that the steering module, essentially the computer brain for the steering, has failed. The repair is overwhelmingly expensive, and I haven’t pursued it due to the crippling cost. When I proceeded to drive the car home, the light was off, and it drove fine. One of the shops I spoke with said this could happen, but it would come back unpredictably, and intermittently until it just won’t be drivable. I’m just glad it was in a safe spot when this failure occurred. Reports I’ve been reading online have scared me with drivers being on the freeway when this component fails, nearly causing accidents in some cases. This seems like a serious safety issue, and certainly not a ‘wear and tear’ issue of daily use. The shop reported the repair would cost $2400 before taxes. I bought this car used for $5000 last year, and so far have had to put in a whole new front end, replace the cooling/ heating reservoir system. So throwing in that much more money into it is having a very negative impact on my livelihood. Other drivers report this issue occurring at anywhere from 60,000 miles to 150,000 miles. My car is at 128,000 miles.
