2020 Ford Mustang Problems

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.

The contact owns a 2020 Ford Mustang. The contact stated while the vehicle was parked, the contact noticed smoke coming from underneath the hood. The vehicle was unoccupied. The contact inspected the vehicle. The contact stated that the fire was about three inches from the back of the engine, close to the fire wall. The contact used a nearby fire extinguisher and extinguished the fire. The contact stated that upon further inspection of the vehicle, the contact noticed brake fluid on the ground underneath the vehicle. The vehicle was towed to the dealer, however the diagnostic test had not been completed. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The contact stated that the failure was a known failure with the vehicle. The manufacturer was not made aware of the failure. The failure mileage was approximately 41,331.

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.

Check engine light came on, car lost power on highway. Car continues to have the same issue after repairs have been made. Ford App says engine misfire, after every repair. Ford mechanics fix spark plugs, coils, electrical. None of which has fixed the issue of stalling on the highway which poses risk of me the driver and others driving on the highway. The only light that comes on is engine light.

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.

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.

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.

Went to Clay Cooley Ford in Arlington TX off of highway 360 to have rearview camera issues fixed after being sent a recall notice to take it in to be repaired. The vehicle doesn’t show a black screen all of the time but it is at times distorted or black. Upon arriving my husband was told that one they don’t have the camera for the vehicle mind you an appointment was made I didn’t just show up and two because at this present moment the screen wasn’t showing distorted or black screen they were not able to repair the recall we were given a paper to contact a man who works at the dealership the vehicle camera wasn’t thoroughly inspected, just asked if it was doing it now when my husband said not right now but it does show a black or distorted screen sometimes he was sent on his way and told the repair couldn’t be done. I have reached out to Ford customer service to get their help with getting this recall resolved because I do transport a child in this car daily to and from school.

My wife was pulling into her head-in parking space at work and the brakes did not slow the car down. She pressed the brakes hard. The car went over a curb and hit a fire hydrant. The fire hydrant broke off and the car rolled over it. The car went into the street and she steered it to keep it out of traffic and stopped by using the parking brake. There were no warning lights. The airbag(s) did not deploy. There were no personal injuries. The car was inspected by a repair shop and deemed a total loss. A brake line was damaged during the crash. The repair shop personnel did not think the brakes failed prior to the accident because the master cylinder had fluid in it. No other brake inspections have been done.

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.

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.

My 2020 Ford Mustang Ecoboost has a (P008A) AND (PO18B/PO18C) The fuel pressure fuel system you low and fuel pressure Sensor B is a well documented defects and has a customer satisfaction program 21N10 (or related TSBs). The dealer said there are no recalls under my vin number and vehicle was not repaired. I sent a certified letter to ford March 29, 2026 to Ford Motor Company and I have had no response. 2015 thru 2022 Mustangs have this well known defect. 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

- The light of the airbag and seatbelt came on my dashboard, went to the dealership and they told me that there's an issue with the control module, apparently there is a recall for that but since my car wasn't called they could repair. - Backup camera goes completely off when trying to go on reverse.

Brake light stop switch replaced 2/2/23. Now brake lights cut off if any pressure is released but foot is not removed from brake pedal. Additional harder pressure is required for brake lights to come back on. Brake lights will flicker and then cut off while foot is on brake pedal. Intermittently comes on as it should. This is an extreme safety hazard.

RENTING VEHICLE FOR LONG TERM USE. DRIVE AS MOSTLY SINGLE WOMAN AND COMMUTE UP TO 2 HRS. SIDE LIGHTS ARE ATTENTION GRABBER FOR NIGHT TIME USE. EX DRIVING ON 8 AND STOPPING AT REST STOP OR FOR GAS DREW MUCH UNWANTED ATTENTION. MY CELL PHONE SLID UNDER PASSENGER SEAT AND I HAD TO EXIT VEHICLE MOVE CAR FORWARD AND BACK TO TRY AND PRY OUT. THIS COULD HAVE BROKEN MY NEEDED MEANS OF COMMUNICATION OR HURT MY HAND AS SEAT IS LOW FOR BETTER COMFORT BUT NO ROOM TO GRAB THINGS UNDERNEATH. ALSO BACK SEATS STRAP TO ALLOW ENTRY TO TRUNK. AS AN ADVOCATE THIS IS AN EASY ACCESS TO STOW AWAY PASSENGERS OR HAVE SOMEONE HIDE IN TRUNK. THE TRADITIONAL STRAP IN BETWEEN SEAT AND MUCH TIGHTER MAKES THIS MORE OF A PROCESS BUT WOULD MAKE MORE SENSE TO DRIVERS LIKE MYSELF AS A VICTIM OF SEXUAL ASSAULT. THANK YOU FOR YOUR TIME.

Periodically receive indication of 1) Steering assist fault service required 2) Hill start assist not available 3) advancetrac unavailable. While these messages appear on the dash, the electric power steering system fails. This happens frequently, where there is no power steering when operating vehicle. Could be potentially dangerous while making low speed turns. The system is up to date. Local Ford service center believes the problem is the motor of the steering rack. The part is on back order with no indication of the dangerous problem being repaired any time soon.

3 lug nuts on the front passenger side wheel snapped and broke off while driving in highway.

This vehicle has been in an accident with damage exceeded $5000.00 (I have a Ford Dealerships estimate to prove damage on the vehicle has not been eepaired nor reported) Again, substantial, front drivers side, hood, wheel, breakline, door and underbody damage occurred to this vehicle. It was never reported to Carfax nor any online reporting agency. This vehicle is being resold with a 'clean' carfax because damage has never been reported.

Tire size: 255/40 ZR19 Our vehicle only has 14,757 miles and these tires lack good traction under normal driving conditions. In more than one occasion, the vehicle would start fishtailing when entering a highway from a side street. So far, we have been lucky and managed to keep the vehicle from leaving the roadbed or crashing into another vehicle. However, every time this happens, we get the scare of our lifetime.

I was contacted by the NHTSA, after I had an accident in my 2020 Ford Mustang EcoBoost with the automatic transmission and ability to manually shift. I spoke with an Investigator by the name of [XXX]. The investigator wished me good luck, as it was relayed to me that I was the only one who had the problem which resulted in me having an accident. I have since then found multiple sites with multiple complaints of the same issue, and I was told that there’s a Fourth Class Action Suit right now that I should be a part of. Please have someone who is familiar with what’s going on with Ford call me at: [XXX]. Thank you for your help!
