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. …
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. …
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. …
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. …
During some Christmas shopping within the past few weeks, my cars power steering went out completely with no warning or sounds to repair or seek assistance. Not only was my life in danger, but the safety of others in the vehicles surrounding me. I couldn't even turn my wheel if I tried. There have been other instances in other cars where I could strong arm the wheel and be ok, but there was absolutely nothing I could do about turning the wheel whatsoever! When my dad came with power steering fluid, we discovered that these cars don't even have a reservoir for power steering fluid and that this was more than likely a battery or module issue or worse the power steering pump. This is ridiculous that there is no service light or warning that the power steering is going out or losing power. Ford should fix this because it seems like this is an ongoing issue with Fords in general
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
Our Ford Focus BEV had a recall in 2014 (Ford# 15N03) It is a high voltage wire harness issue. The car will completely cut power to the drivetrain and shut down leaving a message on the dash saying "Stop Safely Now". We took it in for the fix in 2014 however the issue still continued after about a year and continues still. My wife just had this happen to her with the kids in the car. This issue puts the driver and passengers in very serious danger when the car just stops responding while moving in traffic. Ford said they would not recall the issue since the issue was "fixed" and that wire harness was only good for a 1 year warranty which expired in 2015. I am hoping Ford will do the right thing and fix this issue for good. Thanks for your help in this matter. -Dave
