The rotary gear shift dial has malfunctioned on my teenager's vehicle. His safety was put at risk because it started lighting up as he was driving on a very busy highway the first time that it was noticed to have happened. On 5/26, the vehicle would start, it physically felt like it shifted into the d gear, but would only drive maybe 1 foot until the car was force stopped and said "shift sys fault" the vehicle has been inspected and diagnosed by a veteran mechanic, with being able to reproduce the issue. He assumed what it was before even inspecting it. We live in a smaller town, and he informed me this morning that he's replaced 7 of these in the last calendar year alone. What is completely asinine, is the fact that Ford is no longer making this part, so we have to find a used one at a junk yard. Other than this issue, his car has appeared to be in very good shape, has been maintained well and clean. Why is there not a recall on this issue?.

At approximately 67,180 miles, a Ford dealership performed a multi-point inspection on my 2018 Ford Fusion se with the 1. 5l ecoboost engine due to a check engine light on. The Ford dealership diagnosed the vehicle with a coolant intrusion into cylinder 2. The Ford dealership recommended the replacement of the short block and gasket kit, with an estimated repair cost of $7,465. This type of issue diagnosed for my vehicle is a known failure issue for 1. 5l Ford ecoboost engines documented in customer satisfaction program 21n12, which covers coolant intrusion and engine damage in this engine type. Despite the Ford dealership diagnosis of my vehicle matching what is described in customer satisfaction program 21n12, I was informed that my vehicle is not eligible. The coolant intrusion into cylinder 2 is an issue that poses a safety risk due to engine misfires, stalling, overheating, and possible sudden loss of engine power while driving. In my case, my vehicle has become unreliable and unsafe for regular driving. A Ford dealership inspected the vehicle, confirmed and documented the issue, and the repair quote, diagnostic report and diagnostic payment receipt are available upon request. Ford has declined assistance despite the vehicle’s low mileage and clear alignment with known engine defects. I mailed a formal appeal letter to Ford motor company and I am filing a complaint with my state attorney general. This widespread issue affects customer safety, and vehicle safety standards and deserves further investigation, as many other Ford owners of vehicles with 1. 5l ecoboost engines have reported similar failures.

The 6f35 transmission in both of our Ford vehicles that we drive daily for work and school. The Ford Fusion is currently in the shop, but the Ford escape is available for inspection. My safety was put at risk as my Fusion suddenly, without warning, stopped accelerating in the middle of a 2 lane highway, very unsafe. My daughter's escape is putting her safety at risk because she has the same 6f35 transmission, the car is still "drivable" at the moment but not safely drivable, with the rough shifting between 2nd-3rd gear, the slow acceleration and sometimes won't go into gear, her safety is at risk. Like many other Ford owners with this transmission, the car will end up breaking down and needing $5000 in repairs. Yes the issue has been reproduced by the service center. No, Ford has not reached out to me, I have left 7 messages without any return calls, I have sent multiple emails that were returned to sender. There were no warning lights, messages or problems on the Fusion prior to this happening. I own two Ford cars that are both undrivable, I cannot get to work, my daughter cannot get to work/school. Ford is very aware of this transmission issue but will not issue a recall. Also at times when I put my Fusion into drive, from reverse, the backup camera would stay on for a few minutes which makes driving very hard/confusing and very unsafe. Ford needs to take accountability and issue a recall for vehicles with this defective transmission instead of ignoring the issues and telling buyers their vehicles are reliable.

The failure mileage was approximately 111,700.

I am reporting a serious safety defect involving the transmission system of my Ford Fusion, specifically related to the valve body and torque converter. The malfunction of these components causes sudden, unpredictable surges or lunges in acceleration, even when the vehicle is being driven at steady speeds or when lightly applying the accelerator. The issue appears to stem from improper pressure regulation or fluid flow within the transmission valve body, which causes erratic shifting and delayed engagement. When this malfunction occurs, the torque converter can fail to properly manage torque transfer, resulting in sudden and forceful forward motion of the vehicle. While driving on a highway at approximately 65 mph, my vehicle suddenly lurched forward aggressively, as if it had downshifted or received a surge of power without any change in throttle input. This caused the car to rapidly accelerate momentarily, nearly causing me to lose control. The unexpected forward thrust startled me and forced me to take immediate corrective action to maintain my lane and prevent a collision with a nearby vehicle. In another instance, while slowing down to a stop, the car lunged forward again instead of decelerating smoothly, nearly causing me to roll into an intersection. This created a dangerous situation for myself, my passengers, and surrounding traffic. This defect creates a significant risk of collision due to the vehicle’s unpredictable acceleration behavior. The driver cannot reliably control speed or anticipate when the car may suddenly surge forward. The issue compromises both vehicle stability and driver reaction time, particularly at higher speeds or in traffic. If this problem were to occur in a congested area, at a stoplight, or near pedestrians, it could result in a serious crash, injury, or fatality. The failure of the valve body and torque converter in the Ford Fusion represents a critical mechanical defect that directly impacts safe operation of the vehicle.

In 5/2025 I had the transmission light come on my dashboard, then it went away. 2 days later I could not shift my car into drive only reverse or neutral. When I popped the hood the shifter cable was detached and the bushing was in pieces. I purchased the Ford oem parts and replaced it. Today 10/8/25 the light appaired on my dash again. When I got home I popped the hood and the bushing was in pieces. Luckily I had purchased 2 replacement parts in may. I replaced it and it seems to be working. But I should not have to replace them this often. Today 10/8/25 I am purchasing 2 more just in case. But can we get this fixed with something more sturdy.

My car is at 47,000 miles and I started to hear a loud noise . Turns out Ford says it’s the flywheel, transmission pump, and torque converter per Ford technician who completed my inspection . No warning lights came on nor was there any alerts the Ford app. My 2020 Ford Fusion with approximately 48,000 miles experienced a cracked flexplate. This caused severe engine vibration, knocking sounds, and ultimately loss of power while driving. A cracked flexplate can lead to sudden engine stalling or failure to accelerate, especially at highway speeds or during intersections. This puts the driver and passengers at serious risk of a crash due to unexpected loss of power or control. This issue happened without warning and is a known problem in vehicles with the 2. 0l ecoboost engine and 6f35 transmission. Ford is aware of the issue (customer satisfaction program 22n12), but my VIN was not included, even though the symptoms and components match the defect. I am reporting this because it jeopardized my safety and others on the road, and I believe more vehicles should be covered under the existing csp or a recall.

The contact owns a 2017 Ford Fusion. The contact stated while the vehicle was parked, the gear shifter failed to shift as intended. The contact stated several unknown warning lights were illuminated.

I purchased a used 2020 Ford Fusion from carmax n 2023 with about 56,800 miles. A week later was involved in a nor side impact accident on the back end driver side, insurance paid for a dinted door and there was no other issues with the vehicle according to sons Ford. In 2024 I was on the highway (going about 80 mph) when my engine light came on, no more than 3 minutes later all the lights in my car flickered and I lost power to my entire car almost causing me my life, roadside assistance and a mechanic who had thankfully pulled over explained that my alternator completely shredded my belt. I paid for both my alternator and belt to be replaced but most recently (2025) I continued to whirring and knocking noises for 3 days (no warning lights) , I took it to firestone who stated I needed a motor repair so I got it towed to the dealership. A Ford certified mechanic stated my flex plate was cracked and it begin breaking off and how I needed a new starter as well leaving the car inoperable. They confirmed this was very uncommon due to the car age and the miles on it (80,000 mi) I’ve also reviewed the complaints on NHTSA and it looks like a lot of 2020 Ford Fusions are having these issues but yet no recall.

The flexplate in my 2020 Ford Fusion se (1. 5l ecoboost engine) failed at just over 53,000 miles. The car began making loud knocking and rattling noises while driving, and it vibrated heavily at idle and during acceleration. This posed a serious safety concern, as we feared the car could stall or break down while on the road with our toddler in the backseat. We took it to an independent, certified repair shop where they diagnosed a broken transmission flexplate, which required immediate replacement. The repair cost nearly $3,000, and the shop confirmed it was not caused by driver error or normal wear-and-tear. The failure was premature and mechanical in nature. The mechanic informed us that this specific engine and flexplate design have been recalled before in other Ford models using the same 1. 5l ecoboost engine and parts. They suggested we contact Ford, as this appeared to be a known defect that should be covered under goodwill or extended warranty. We followed their advice and reached out to Ford directly, but Ford refused to offer any assistance — even though they are aware of these ongoing flexplate failures across similar vehicles. After researching, I discovered Ford has had multiple flexplate and powertrain-related recalls in other 1. 5l and 1. 6l ecoboost engines in previous model years. I also found many online complaints from other Ford owners experiencing the same flexplate failures, often at similar mileage. Yet, this issue has not been acknowledged or recalled for the 2020 Ford Fusion se. This is clearly a design or manufacturing flaw that should be investigated by the NHTSA. Flexplate failure puts lives at risk and results in major repair bills for consumers. Please investigate this ongoing issue before someone is seriously hurt.

Occasionally, the vehicle will drive in reverse when started and the shifter knob is turned to drive (forward). This has occurred at least 5 times and the dealership has not been able to replicate the issue. So in their minds, it is not an issue. On one of those instances we noted that that shifter did not have any mode highlighted even though it was put into drive. There were no warning lamps illuminated, no system messages. The car simply started to reverse when taking the foot off of the brake. The car had to be turned off and restarted multiple times to get it to go forward. This can be dangerous as one could inadvertently strike an object or person that is behind the vehicle.

Component or system that failed: flex plate, engine electrical system, and alternator (possible related failures). The issue has been diagnosed by a licensed mechanic and is available for inspection upon request. Incident description: on April 15, 2025, while driving my 2020 Ford Fusion se 1. 5l turbo, the vehicle suddenly experienced a total power failure. The check engine light began flashing, and the battery light blinked rapidly. Within seconds, the engine shut down completely while I was mid-drive in traffic, leaving me stuck and unable to move for over 20 seconds. This was a terrifying and dangerous situation that nearly put my life at risk. I was eventually able to restart the vehicle, but it began shaking and rumbling violently — worse than ever before. This issue was never present before my car was involved in two separate collisions, where both other drivers were found 100% at fault. The vehicle was repaired at fix auto santee (a usaa-assigned body shop), but they failed to inspect internal components. A licensed mechanic at j&l auto care later confirmed a broken flex plate and advised it was unsafe to drive. This problem has not been addressed or fixed by the responsible insurers (usaa and aaa) or the body shop. It has progressively worsened and now created a life-threatening situation. Warning lamps or symptoms before failure: a rattling and vibrating noise began immediately after I picked up the car from the body shop in March 2025. No lights were initially present. The electrical and engine lights only appeared on April 15 when the engine shut down mid-drive. Inspected •independent service center (j&l auto care, diagnosed flex plate failure) •usaa and aaa were informed but refused to cover or further inspect the damage •fix auto santee heard the issue but refused to inspect, citing body-only service problem available for inspection: yes — vehicle is currently undrivable and available for full inspection.
