Recalls on the 2020 Ford Mustang

A complaint is one owner's allegation. A recall is the point at which the manufacturer or a regulator agreed the defect is real and dangerous enough to fix for free — however old the car is.

Canada — Transport Canada

Canada runs its own recall programme, and its campaigns do not always mirror the American ones.

Recall 2025707 55 units in Canada

Powertrain

Issue: On certain vehicles, the recall repairs completed by a Ford dealer during recall 20S21 (Transport Canada recall no. 2020-203) may not have been done correctly. As a result, a second repair is required. On certain vehicles, there is a problem with the warnings to tell a driver that the transmission is not in Park. When the ignition is turned off, with the driver door closed, the message and chime to warn that the transmission is not in Park are only active for 3 seconds. Instead, the chime should sound for 10 seconds and the message should display for 30 minutes. As a result, a driver could exit the vehicle without realizing that the transmission is not in Park. If this happens, the vehicle could roll away. Safety Risk: Unintended vehicle movement could increase the risk of injury and/or a crash. Corrective Actions: Ford will notify owners by mail and advise you to take your vehicle to a dealership to reprogram the instrument panel cluster.

Recall 2025703 117 units in Canada

Lights And Instruments

Issue: On certain vehicles, the recall repairs completed by a Ford dealer during recall 23C35 (Transport Canada recall no. 2023-587) may not have been done correctly. As a result, a second repair is required. On certain vehicles, a software problem could cause the low brake fluid warning lamp not to turn on if the brake fluid level gets too low. A low brake fluid level can cause reduced braking. Safety Risk: A driver that isn't aware of a low brake fluid level could experience reduced braking and an increased risk of a crash. Corrective Actions: Ford will notify owners by mail and advise you to take your vehicle to a dealership to update the body control module software (BCM).

Recall 2023587 13,917 units in Canada

Lights And Instruments

Issue: On certain vehicles, a software problem could cause the low brake fluid warning lamp not to turn on if the brake fluid level gets too low. A low brake fluid level can cause reduced braking. Safety Risk: A driver that isn't aware of a low brake fluid level could experience reduced braking and an increased risk of a crash. Corrective Actions: Ford will notify owners by mail and advise you to take your vehicle to a dealership to update the body control module software (BCM).

Recall 2022278 3,563 units in Canada

Electrical

Issue: Under certain conditions, the powertrain control module (PCM) may incorrectly detect a fault in the transmission. If this happens, the reverse camera, reverse lamps, and different driver assistance technologies may not work properly. This includes traction control, forward collision warning, blind spot warning, and cross traffic indicator. Note: This recall only affects vehicles equipped with a 5.0 L engine and a manual transmission. Safety Risk: Reverse lamps that don't turn on could cause others not to recognize when a vehicle is backing up. A rearview camera image that doesn't display could reduce a driver's ability to see behind the vehicle while backing up. These issues and driver assistance technologies that don't work properly could increase the risk of a crash. Corrective Actions: Ford will notify owners by mail and instruct you to take your vehicle to a dealership to update the powertrain control module (PCM) software.

Recall 2020647 99 units in Canada

Brakes

This equipment recall is for replacement parts that were sold or installed by Ford dealerships between October 2019 and August 2020. This recall is not being conducted under the requirements of the Motor Vehicle Safety Act. Issue: On certain cars, the brake pedal and bracket assembly could fracture if rapid and forceful pressure is applied to the brake pedal, as typically seen during track and competition driving. If this happens, there could be a loss of braking. Note: This equipment recall only affects the following brake pedal and bracket assembly part numbers: FR3Z-2455-AA FR3Z-2455-AB Safety Risk: A loss of brakes can create the risk of a crash. Corrective Actions: Ford will notify its dealers of this recall. While dealers will attempt to contact people who may have purchased a part affected by this recall, if you have had the brake pedal and bracket assembly replaced on your car, you should contact the dealer that sold or installed it to find out if it is affected by this recall. Any part that is affected by this recall will be replaced, free of charge.

Recall 2020485 833 units in Canada

Lights And Instruments

Issue: On certain vehicles, a software problem may cause the daytime running lamps (DRLs) to not turn on. Note: This recall only affects Shelby GT350 and Shelby GT500 models. Safety Risk: Daytime running lights that do not work could make the vehicle less visible to others and increase the risk of a crash. Corrective Actions: Ford will notify owners by mail and instruct you to take your vehicle to a dealer to update the body control module (BCM) software.

Recall 2020454 76,576 units in Canada

Visual System

Issue: On certain vehicles, an electrical problem with the rearview camera could cause it not to work properly. As a result, the rearview image may be distorted or not display at all. Safety Risk: A rearview camera image that does not display could reduce a driver's ability to see behind the vehicle while backing up. This could increase the risk of a crash. Corrective Actions: Ford will notify owners by mail and instruct you to take your vehicle to a dealer to replace the rearview camera.

Recall 2020450 2,251 units in Canada

Brakes

Issue: On certain cars, the brake pedal bracket could fail during sudden braking. If this happens, there could be a loss of braking.

Macomb, MI Crash

SEATS

On [XXX], I was involved in a front-left collision while driving my 2020 Ford Mustang GT (VIN: [XXX] ) with my [XXX] daughter in the front passenger seat. She weighs approximately [XXX] and was properly seated with her seatbelt fastened. The only airbag that deployed was the driver’s knee airbag. The front passenger airbag did not deploy at all. After the accident, the FordPass system reported multiple “Restraints Indicator Lamp Warning” alerts, all timestamped the day of the crash, stating: “Your Air Bag Warning is on due to an issue with the front passenger air bag system. The front passenger airbag may not work properly.” This alert was not visible on the dashboard prior to the crash and was only discovered after checking the app. This failure of the airbag system placed my daughter at serious risk. A properly seated child passenger of sufficient weight should have been protected. The vehicle had approximately 19,177 miles at the time of the accident and had no prior airbag-related service or known damage. The crash occurred at normal road speed during a left turn when another vehicle impacted my front driver-side area. My vehicle is currently with the insurance company and available for full diagnostic inspection by NHTSA or the manufacturer. The passenger-side OCS and SRS systems should be investigated for sensor failure, deployment failure, or manufacturer defect.

Tempe, AZ

POWER TRAIN

2020 Ford Mustang with the 2.3L EcoBoost engine. The vehicle has a documented history of coolant loss with no visible external leak, consistent with the known coolant-intrusion defect in Ford's 2.3L EcoBoost engines where coolant leaks internally into the cylinders. The vehicle previously threw a cylinder misfire code (P0301) and now shows a crankshaft/camshaft timing correlation fault (P0017). A scan tool confirmed the exhaust camshaft is approximately 18–19 degrees out of correlation. A new variable valve timing oil control solenoid was installed and did NOT resolve the fault, confirming the problem is mechanical — a worn/stretched timing chain. This wear is consistent with the oil dilution and contamination caused by internal coolant intrusion. The problem has been confirmed by an independent service center via scan data. The vehicle is available for inspection. Warning symptoms included the check engine light, a loud rattle on cold startup, and occasional hard/no-start conditions. This is a safety concern because internal coolant loss can cause overheating, cylinder head cracking, and potential engine failure or fire while driving. Repair cost quoted at approximately $2,000. Mileage approximately 54,400.

ELECTRICAL SYSTEM

I suspect an electrical problem/short is causing my passenger side window to open and close about half an inch uncontrollably. This has been a minor inconvenience but last time it happened, it triggered the passenger door to open when driving. I had to pull over to manually secure the door. Very troubling safety issue.

Seattle, WA

POWER TRAIN

The 10-speed automatic transmission on my 2020 Mustang failed internally at approximately 18,073 miles. The vehicle began shifting harshly at low speeds with an intermittent clunk. While driving, the transmission would slip slightly and then either surge forward or hesitate with a dull thud before engaging. The behavior was unpredictable and worsened over time. No warning lamp ever appeared and no diagnostic trouble codes were stored, so the driver gets no advance notice of this condition. This is a safety hazard when pulling into traffic, turning across an intersection, or merging. When power arrives late, abruptly, or not at all, the driver cannot judge a gap in traffic reliably. An authorized Ford dealer verified the concern on a test drive, confirmed the vehicle failed the CDF clutch cylinder leak test, and documented an internal tapping noise in Drive and Reverse. Fluid level was in spec. The dealer performed Ford TSB 25-2475, which addresses harsh and delayed shifting on this transmission: the unit was removed, torn down on the bench, the CDF cylinder replaced, and the unit reassembled and reinstalled. It did not correct the concern. The dealer's written notes state the concern was still present, the TSB did not cure it, and the transmission has an internal failure requiring replacement. Independent transmission specialists I consulted all recommended full replacement rather than rebuild, citing known problems with this transmission in this model year. Ford has revised multiple technical service bulletins on harsh and delayed shifting for this transmission over several years. My vehicle failed at roughly 18,000 miles, far under the 60,000-mile powertrain warranty limit, but Ford declined assistance because the five-year time limit had passed.

Plainsboro, NJ

ENGINE

I own a 2020 Ford Mustang EcoBoost with approximately 75,000 miles. My vehicle developed a check engine light with diagnostic codes P0300 (random misfire) and P0301 (cylinder 1 misfire). I also began experiencing white smoke from the exhaust during cold starts. An independent repair shop suspects coolant is entering cylinder 1 due to a possible head gasket failure. They have recommended removing the cylinder head to inspect for cracks, check for warping, pressure test the head, inspect the cylinder walls, and replace the head gasket and related components if no further engine damage is found. The vehicle was properly maintained, and these symptoms appeared unexpectedly.

My car has always been a little rough on shifting since around 40k miles when I got it. I never really noticed after awhile and never had any problems. No lights flashing or codes no issues with anything under the hood. The other day my trans light popped on, but nothing was wrong the car was still driving fine. I took it in to get looked at the first shop said no codes were popping up and then I took it to another and they said the whole transmission now needs to be replaced. I went to look around and apparently a lot of people have issues with the transmission on the 2020.

AIR BAGS

My husband was notified via the Ford app that there was an issue with his airbag system. He called the dealership and set up an appointment. We brought in the car to German Ford dealership in Beavercreek on 4 May, where they confirmed that the airbag was bad and needed to be replaced. They confirmed it was the airbag on the drivers side knee. The airbag light did come on, but we were under the impression airbags usually last the lifetime of the vehicle. Thankfully the car warranty covered the replacement, and we just had to pay the deductible. However, had my husband been in a crash that airbag would not have deployed, there is also the chance that the airbag could have deployed randomly while he was driving, which would have caused a potentially fatal crash.

I am not sure why the 2020 mustang has not been issued a recall. It's the same identical part as the other years Mustangs that have been recalled

FAILURE TO NOTIFY/ADDRESS A KNOWN ISSUE DURING THE WARRANTY PERIOD Vehicle has been serviced in accordance with Ford’s recommended maintenance schedule by Joe Cooper Ford of Edmond, Oklahoma, since purchase. At service appointment in September 2025, with 59,968 miles – just prior to the 60k mile powertrain warranty expiration – specifically requested a thorough inspection of any conditions that could potentially be addressed under warranty coverage. During that visit, Joe Cooper Ford documented that the “coolant was low (at minimum mark) and dirty” and recommended a coolant system fluid exchange. This finding occurred in the context of the well-documented coolant intrusion defect affecting 2017–2020 Ford Mustangs and other Ford models. When an authorized dealer observes conditions consistent with a known defect during the warranty period, reasonable warranty administration requires disclosure and further diagnostic evaluation, so the customer has a meaningful opportunity to pursue timely repair. By January 2026, at only 61,640 miles, were informed our engine had failed. No such disclosure or evaluation was provided. As a result, we were deprived of a reasonable opportunity to address the condition under warranty prior to expiration. The subsequent engine failure occurred after the warranty period but was directly preceded by these unresolved indicators. Under these circumstances, denial of warranty consideration is inconsistent with the purpose of the warranty and reasonable consumer expectations.
