2020 Ford Fusion transmission problems

POWER TRAIN

A failed transmission cooling line caused the transmission fluid to leak. At no point did the vehicle display a check engine light, transmission warning, or any other indication that there was a problem. According to the Ford dealership, the transmission fluid had been leaking for some time. Because the transmission pan is wrapped in a fabric-like insulating material, the leaking fluid was absorbed rather than dripping onto the ground, making the leak virtually impossible for an owner to detect during normal use. The dealership also advised that this condition could have created a potential fire hazard within the engine compartment. The vehicle has only approximately 40,000 miles, making this type of catastrophic transmission failure especially concerning for a relatively low-mileage vehicle. The first and only symptom occurred when I started the vehicle one day. It hesitated, struggled to shift out of first gear, and drove abnormally. I immediately drove it to the Ford dealership, where it was diagnosed with a complete transmission failure. The vehicle is currently at the dealership, and I have been presented with an estimated repair cost of approximately $12,000. My primary concern is that there was absolutely no warning before this major failure. No warning lights, no diagnostic alerts, and no indication that a significant transmission fluid leak or internal transmission damage was occurring. A safety-critical failure of this magnitude should provide drivers with some form of warning before resulting in complete transmission failure.

I’ve learned a while ago that the vehicle doesn’t have a working horn, I’ve replaced the fuse at least five times and it’s still not working. Yes the car was sold to me this way. Also I’ve been getting this warning to my ford app: “The Blind Spot Information System (BLIS)/Cross Traffic Alert (CTA) has detected a fault and may not function. What Should I Do? If either BLIND SPOT NOT AVAILABLE/SENSOR BLOCKED SEE MANUAL or CROSS TRAFFIC NOT AVAILABLE/SENSOR BLOCKED SEE MANUAL is in the information display, the system may not function. Check the exterior vehicle sensors for damage or debris covering them (see Owner's Manual for sensor locations). If the problem persists, please have the system checked by an authorized dealer.” For the last month my car has become hard to drive as if there’s a power steering issue.

In early October 2025, the vehicle was taken to an independent dealership service department for a routine oil change. Several weeks later, the vehicle appeared to be leaking fluid and began experiencing loud knocking/clacking noises, significant vibration, and drivability concerns, especially during acceleration. On October 10, 2025, while parked at a family member’s residence, the vehicle would not start. Due to safety concerns, the servicing dealership arranged for the vehicle to be towed for inspection. Technicians found a split transmission hose causing transmission fluid loss, which was repaired; however, the abnormal noises, vibration, and drivability issues persisted. Further inspection identified loud popping/clacking noises from the bell housing area. The technician physically inspected the flex plate and documented that the flex plate was cracked. The dealership advised that a cracked flex plate can worsen, cause severe vibration, damage related components, and lead to drivability issues or potential loss of propulsion. Because of the nature of the failure and symptoms, the vehicle was removed from regular use due to safety concerns. The vehicle was later taken to a manufacturer-authorized Ford dealership, which confirmed flex plate failure but stated the vehicle did not qualify for a customer satisfaction program due to engine variant. A goodwill/financial assistance request was submitted and denied. Technician diagnostic documentation from the manufacturer-authorized dealership was requested but not provided prior to filing this complaint. No crash or injury occurred; however, the failure created a risk of sudden inability to propel the vehicle while driving, including at highway speeds. The vehicle remains unrepaired and parked due to cost and safety concerns.

When these problems started it was only 6 months after purchase and I was already having issues with power train malfunctions and it didnt want to switch gears. I purchased this at roughly 47,000 miles and it didnt make it to 70,000 miles before I ultimately decided it was not the safe vehicle that was advertised to my family and I. It was taken to the dealership over 3 times in under a year and for some reason the problem never got resolved. I have been sued for the remaining balance now despite that toward the end of my time owning it the vehicle was reving out with barely any pressure on the gas pedal, having issues braking on its own (anti-collision assist), and occasionally the steering wheel would jerk me in to oncoming traffic. I am just trying to get a recall issued at this point because this car is going to kill someone if it stays on the road.

My Ford started making a loud noise whenever the accelerator wasn't being pressed, after taking it to the mechanic, he said it is the cracked flex plate. After some light research, it was aparent that this is an issue that Ford's cars have, and ford has tried to make it better by offering free fixes. I contacted the local ford dealer and since the car has 90,000 miles, it would have been covered. However, since it doesn't have a clean title, I was declined this service free of charge. I don't agree with this decision since I've been driving this car for over a year since it was purchased off IAA auction, and this issue was made clear only yesterday, but this issue is prevalent in cars like mine.The damage to my car specifically was to the back, and only affected the rear bumper and trunk. Therefore I don't think it is fair that I was declined the serve even though Ford has made it clear it is there manufacturing mistake and they are willing to fix it, just not with cars with my type of title. I was hoping to send in this incident so that this issue becomes a national recall, and more people can get their cars rightfully fixed and aware of this serious issue that can make the car completely unusable before it gets too late. I wasn't aware this was a common issue when purchasing this car, so a recall would protect more people since it will become mandatory information for owners to be aware of this issue. Thank you!

VIN: [XXX] Issue Category: Powertrain / Flex Plate / Transmission Failure Dealerships Involved: Freeway Ford – Bloomington, MN J.C. Lewis Ford – Savannah, GA Summary: I am requesting reimbursement from Ford Motor Company for repeated flex plate repairs and a resulting transmission failure on my 2020 Ford Fusion. The vehicle has had five flex plate replacements — three at Freeway Ford in Bloomington, MN, and two at J.C. Lewis Ford in Savannah, GA. Despite all repairs being performed by Ford dealerships, the issue persisted, and the transmission ultimately failed. I was required to pay for a new transmission out of pocket, even though the repeated flex plate failures clearly caused the damage. Ford has a Customer Satisfaction Program (CSP 22N12) addressing flex plate issues on this model, but I received no reimbursement or coverage. I contacted Ford via email to crcfmc@ford.com with documentation but received no response. I have copies of all invoices, repair orders, and service notes from both dealerships to support my claim. I am requesting full reimbursement of all related costs under goodwill or warranty consideration, as this is a known manufacturer-related defect that led to a major drivetrain failure. Total $3,103.93 Requested Resolution: Reimbursement for all flex plate repair costs and the transmission replacement due to defective parts covered under CSP 22N12.

My 2020 Ford Fusion has experienced three separate flexplate failures, as well as transmission issues following the most recent repair. Failure #1: Occurred before I owned the vehicle (confirmed later in the vehicle’s history). The flexplate was replaced by a prior owner in 2022. Failure #2: [8/2023] – While I owned the vehicle, a loud rattling noise came from the engine area. My vehicle was towed to Foothill Ford, where it was purchased, and they replaced the flexplate. No power loss occurred. Failure #3: [5/2025] – The same rattling sound returned. I drove it to Green Ford, who confirmed the flexplate needed to be replaced, and they replaced it. No power loss occurred, but the noise was severe. After the third flexplate replacement, the transmission began slipping during acceleration. This issue did not exist before the repair, and Green Ford had told me the transmission was fine before they replaced the flexplate. Safety concern: Repeated flexplate failures and subsequent transmission slipping could cause loss of propulsion or difficulty maintaining speed if the problem occurs at highway speeds or in heavy traffic, creating a potential crash risk. I did lose power on the highway, but was able to pull safely off the shoulder and called a tow truck.

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.

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.

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.

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 by: •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.
