Ford Mustang jerking problems

Filed Oct 28, 2026 · Engine · NC

A blank instrument cluster will not show important information like vehicle speed, fuel or temperature level, or safety system warnings. Gas pedal doesn't act and doesn't even effect the car's engine. And suddenly it catches up and jerks.

I am filing a formal safety complaint regarding a catastrophic Electronic Power Assisted Steering (EPAS) failure and severe electrical short circuit on my 2015 Ford Mustang. This vehicle is exhibiting hard fault code B137F:09 (Steering Wheel Left Switch Pack: Component Failure / Short to Ground or Open). This electronic failure creates an immediate, severe safety hazard that goes entirely outside the scope of normal vehicle wear and tear. While driving, the vehicle's steering wheel pulls and jerks violently on its own, actively fighting my manual steering inputs. Furthermore, this internal electronic short creates a massive parasitic electrical draw that prevents the vehicle's computer modules from entering sleep mode when turned off. This has resulted in the primary vehicle battery draining completely flat and causing the vehicle to completely shut down, stall, or lose total electrical power altogether. A vehicle that forcefully steers itself away from the intended path of travel and suffers total electrical shutdown is a clear, life-threatening safety risk to myself and others on the road. Ford Motor Company is fully aware of this dangerous defect. They previously issued Safety Recall 15S18 for a very specific, limited batch of early-production 2015 Mustangs experiencing identical EPAS failures, replacing their steering gears for free. For the remaining 2015 Mustang owners experiencing the exact same hazardous failure, Ford quietly shifted the issue over to a Technical Service Bulletin (TSB / SSM 51312). By limiting the scope of Recall 15S18 purely due to the financial cost of a universal recall, Ford has left an entire population of 2015 Mustang owners in direct harm's way. Some owners received a free lifetime safety fix, while the rest of us are being forced to pay thousands of dollars out-of-pocket to correct an identical factory electronic defect. I request that the federal safety agency immediately open an investigation into Ford's handling of the 2015 Mustang EPAS and more.

My 2018 Ford Mustang EcoBoost with the 10R80 automatic transmission began experiencing hesitation, delayed engagement, and harsh jerking during low-speed acceleration (15-20 mph), especially when cold. Engine RPM would increase, but the vehicle would hesitate before engaging. The condition worsened over time and eventually the vehicle entered limp mode, causing a significant loss of power and illuminating a wrench warning light. An authorized Ford dealership diagnosed DTC P07F6 (Gear 9 Incorrect Ratio). The dealer verified fluid level, updated the PCM, and performed adaptive relearn procedures, but the problem remained. The transmission fluid was found to be dark with a burnt odor, and the dealer diagnosed an internal transmission failure requiring complete transmission replacement at an estimated cost of $9,250. This created a safety concern because the vehicle did not consistently accelerate as expected when entering traffic, crossing intersections, or merging onto roadways. Delayed engagement and loss of power reduced the ability to accelerate when needed. The vehicle has approximately 82,256 miles and has been maintained according to Ford's recommended service schedule. I am also aware of numerous publicly documented owner reports, technical discussions, and litigation involving the Ford 10R80 transmission used in vehicles from this generation. One of the commonly discussed concerns involves the CDF drum design in earlier 10R80 transmissions. My understanding is that Ford later revised the CDF drum design in subsequent production; however, when I contacted Ford regarding this transmission failure and requested assistance with repair const, they advised that my vehicle was not covered by any recall, customer satisfaction program, or warranty extension related to this issue. I am submitting this report so that my experience can be considered together with other reports to determine whether a broader safety-related defect exists.

The contact owns a 2025 Ford Mustang. The contact received notification for the federal safety agency Campaign Number: 26V122000 (Engine and Engine Cooling); however, the part to complete the recall repair was unavailable. The contact stated that while driving at an undisclosed speed, the accelerator pedal was depressed, but the vehicle failed to accelerate as intended. The vehicle stalled, jerked forward, and the check engine warning light illuminated. The force of the jerk propelled the contact onto the steering wheel. The vehicle was restarted, and the check engine warning light was no longer illuminated. The vehicle was driven to the residence. The contact stated that the vehicle required several attempts to start on some occasions. A dealer was made aware of the failure but confirmed that the recall remedy was unavailable. The vehicle was not diagnosed or repaired by an independent mechanic or a dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 14,000.

The vehicle experienced a sudden steering malfunction involving the electronic steering gear. While backing out of a parking structure, the steering wheel suddenly jerked and locked instead of naturally correcting, resulting in collision with a pillar. There were no warning lights, steering fault messages, or prior symptoms before the incident. Restarting the vehicle did not resolve the issue. The dealership confirmed the issue and documented “loss of communication with steering gear,” “internal steering gear failure,” and “no signs of damage causing failure.” The steering gear is being replaced under warranty. The failure created a safety risk because steering response suddenly changed without warning. I am concerned the incident could have resulted in a more serious crash had it occurred at higher speed or during active traffic instead of inside a parking structure. Multiple tow attempts through Ford Roadside Assistance reportedly struggled to move the vehicle afterward due to the steering issue. The failed steering gear component is currently being replaced by the dealership.

Rebuilt transmissions are bad. Two in the last four weeks have been placed in my 2019 California Special Edition Mustang, and both are bad. They both came from the Ford manufacturer. The transmission locks up at any point while driving at any speed, causing the car to jerk to a standstill, and only while you are driving. We were on 465, and the car automatically stopped in the middle of the highway while other vehicles were flying by and behind me. We were almost hit by several vehicles. This also occurred while the mechanic test drove the car with the second rebuilt transmission placed in my car. No warnings, nothing before this occurred. This is a huge safety hazard and risk for many. The dealership is aware and advised me to contact Ford Motor Company and not to drive my car until something can be done. I have contacted Ford Motor Company, and they have yet to do anything or reach back out to me regarding this safety issue. The car is available for inspection at any time needed since it is still sitting at the dealership with the second rebuilt transmission in it that is no good.

IMRC actuator rod broke causing the air/fuel mix to be sporadic. Creating a misfire on random cylinders. Major loss of power and very jerky motions, causing the vehicle to loose control. Luckily it was on an open spacious road. Unfortunately this has been an ongoing problem and there is nobody selling updated parts the electronics will recognize and very difficult to find oe replacement parts, real costly. And may fix the issue for a short period of time. I have a brand new manifold off of a same totaled mustang since Dec 2025 and the same part broke.

I had parked my car in a spot at an office building. As I was about to put the vehicle in park it lurched forward going over a standard curb across a sidewalk and then into the brick wall of the building. The air bag did not deploy. The car lurched about ten feet total before hitting the wall.

Transmission would hesitate and jerk very aggressively. If trying to accelerate, the car wouldn’t move at all. Constantly jerking or pulling forward very hard when shifting from park to drive or even while trying to accelerate. Problems started occurring near 30k miles. The problem was attempted to be fixed by the ford dealership before by replacing the valve body but due to poor inspection another service center confirmed it is a failed CDF drum.

While driving up hill in low gear, the vehicle suddenly will jerk, a service light will come on, and a powertrain warning will occur. When this happens, it warns that the pre-collision assist is unavailable, as well as the exhaust mode selection. Once this occurs, the vehicle becomes much more difficult to drive as the rev match no longer occurs, the vehicle no longer increases revs as you start releasing the clutch, and when in gear it becomes more jerky as you are driving along. I don't have the experience but I suspect it is essentially in a low power mode with minimal computer aid. After being able to pull off and turn the car off for a number of minutes (not off and on as that does not resolve it), the vehicle returns to normal. This has happened twice now while driving on the same section of roadway in almost the exact same spot. I previously called the dealer after the first time and they told me if it happens again to bring it in. They did not seem interested in looking at it. I will be hopefully doing that tomorrow. I am not sure if it is related, but the vehicle did seem like it was running rich earlier in the day (a slight smell of gas when driving by).
