Common problems reported by 2020 Ford Mustang owners, with recommended fixes and estimated repair costs.

1

10R80 Transmission Harsh Shifting

The 10-speed automatic (10R80) in the 2022 Mustang GT exhibits harsh or delayed engagement, hard shifts between gears, and occasional malfunction indicator lamp illumination. The shifts can be violent enough to cause the car to lurch, particularly during spirited driving.

Solution

Ford issued a TSB for 2022-2023 Mustang vehicles with the 10R80 addressing PCM software calibration, solenoid ID strategy, sticking valves in the main control valve body, and CDF clutch cylinder sleeve axial movement. Start with a PCM reflash; severe cases require valve body replacement.

Est. Cost: $0 - $200 for reflash; $1,500 - $3,000 for valve body repair
2

Active Exhaust System Malfunction

Some 2018-2022 Mustang vehicles (non-Shelby GT350) experience active exhaust valve failures, resulting in 'Drive Mode Not Available' or 'Exhaust Mode Not Available' messages on the dash. The exhaust may default to quiet mode and the check engine light may illuminate.

Solution

Ford issued TSB 22-2282 addressing an improperly seated exhaust system. The dealer will inspect and reseat the active exhaust valves and actuators. If the actuator motors are burned out, they need replacement. Updated software calibration may also be applied.

Est. Cost: $0 - $300 for reseat/software; $400 - $900 for actuator replacement
3

Brake Fluid Level Sensor Failure (Recall)

The brake fluid level sensor may not activate the visual warning indicator on the dashboard when brake fluid is low. This means the driver may not be alerted to a dangerous low-fluid condition that could compromise braking performance.

Solution

Ford issued a recall for certain 2020-2023 Mustangs. The dealer will update the body control module software to properly detect and display the low brake fluid warning. Contact your dealer to check your VIN.

Est. Cost: Covered under recall
4

Seat Pan Track Looseness and Clunk Noise

Some 2015-2022 Mustangs experience driver or passenger seat pan looseness, lateral seat movement, or a clunk/thump noise during turns. The seat may shift noticeably side to side over bumps or during cornering.

Solution

Ford issued a TSB identifying worn or loose seat pan tracks as the cause. The dealer will inspect and replace the seat track assembly. Tightening the seat mounting bolts may temporarily help, but track replacement is the permanent fix.

Est. Cost: $200 - $600
5

Headliner Sagging and Gap at Weatherstrip

Some 2018-2024 Mustang coupe models exhibit a sagging headliner or a visible gap where the headliner meets the upper door weatherstrip. The headliner may droop from the roof and worsen over time, especially in hot climates.

Solution

Ford issued a TSB to replace the headliner with an updated version that uses improved adhesive and mounting clips. The repair is labor-intensive but should be covered under the bumper-to-bumper warranty if within the coverage period.

Est. Cost: $0 under warranty; $400 - $1,000 if out of warranty

A software error may cause the rearview camera to display a blank image, or the image may remain on the display after the backing event has ended.

Consequence

A rearview camera that displays a blank image can reduce the driver's view behind the vehicle. A rearview image that continues to be displayed after the vehicle is shifted out of reverse may distract the driver. Both of these situations can increase the risk of a crash.

Remedy

Dealers will update the rearview camera software, free of charge. Owner notification letters were mailed September 4, 2025. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 25S72.

Ford Motor Company (Ford) is recalling certain 2020-2023 Mustang vehicles. The brake fluid level sensor may not activate the visual warning indicator when the brake fluid is low. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 135, "Light Vehicle Brake Systems."

Consequence

Without a low brake fluid warning light, the vehicle may be driven with low brake fluid, reducing braking performance and increasing the risk of a crash.

Consequence

A rearview camera or reverse light that is disabled reduces the driver's rear view, increasing the risk of a crash. Disabled driver assist features (traction control, forward collision warning, blind spot warning, cross traffic indicator) may increase the risk of a crash.

Remedy

Dealers will update the PCM software, free of charge. Owner notification letters were mailed June 15, 2022. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 22S37.

Due to a poor electrical connection, the rearview camera may intermittently display a blank or distorted image. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 111, "Rear Visibility."

Consequence

Reduced rearward visibility can increase the risk of a crash.

Remedy

Ford will notify owners, and dealers will replace the rearview camera, free of charge. The recall began November 17, 2020. Remedy became available on February 1, 2021.

Consequence

If the driver exits the vehicle without the transmission being shifted into park, unintended vehicle movement may result, increasing the risk of injury or crash.

Remedy

Ford will notify owners, and dealers will reprogram the instrument cluster, free of charge. The recall began May 26, 2020. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 20S21.
