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.

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 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.

A 2020 Ford Mustang eco boost premium 2.3L L4 DOHC 16 valve 6-speed manual with push button start convertible top burst into flames on [XXX] at about [XXX]. The entire car and the black box were consumed by flames that spread to my carport, shed and mobile home. From what I read; it might have been designed for a road racing car. I am [XXX] , and requested a small car from Enterprise and this is the only car they had for me. Zero to 60 mph: 4.9–5.7 sec Zero to 100 mph: 13.5–15.5 sec Standing ¼-mile: 13.4–14.3 sec Top speed: 145–155 mph. Why would they have put [XXX] in this car? I drove it as cautiously as I drive my 2011 Taurus. I did nothing to cause this fire. I have reached out to FMC and Enterprise and have finally come to terms that I have to ask for charity to get the home livable. We run a gas generator for one air conditioner, small frig and well pump for water. The roof leaks, the firefighters puled every outlet in the rooms near where the fire entered my home. The electric meter was pulled off my pole as is standard procedure in my county. Now I am begging for a new roof and a new 200 amp box and all new wiring so the county will allow the electric to be connected again. FMC did not design this car well. It caused a disaster for me and my family. I cannot afford a new home, I just want to get this one livable. Entreprises had RIMKUS do a complete investigation which revealed nothing.

I rented a 2020 Ford Mustang on 01/16/2024. I drove it home and didn't use it until 01/28/2024 for short trip to the grocery store. I waited in the car and kept it running while my daughter shopped. The car shut itself off twice, but there were no red warning lights. So I restarted with the push button, and after the trip drove the car home and parked in my drive. Two days later, on 02/01/2024, the car ignited itself and burned so hot it set the carport, shed and mobile home on fire, in that order. The fire department were called out and saved part of the mobile home. The car was seen going on fire before the structures. The rental car company used a fire investigation company who towed the car (for evidence). However, they have not given me their report.

I drove my car for 22 miles, parked, and after less than one hour we heard a loud noise from the house and upon checking, we noticed the car was on fire. The fire and smoke was coming from underneath the hood (left side). The car had recent software update and the collision detection and traction control were turned-off and unable to turn it back on. Not sure if the software update had anything to do with it, but thought it would be good to mention that. The fire department came out and said it may have been electrical.

The gas tank was only getting 10 gallons of gas and not 16 gallons like it was suppose to. We ended up running out of gas on a road trip with our two young daughters in the middle of the night on I-75. The gas tank said you had 100 miles to go before empty and then 3 miles later it would drop to 0 and you were running out of gas. This car was used in street racing which was late devulged to us after we found out that at 20,000 miles a whole new engine was put in without our knowledge when we purchased the vehicle . We took it to the dealer and they put a new fuel assembly unit in it. It fixed the problem a little but never fully. Now, 2 days ago my husband with my youngest daughter ran out of gas again on US-19 and I had to leave work to go get them and gas. Next on the 57 things wrong with this car… 5 days after purchase it had 22 engine warning. Took it back and they replaced the 4th coil and the 4th injector and spark plug. About 3 days later my husband came flying into his work, ran by me grabbing a fire extinguisher and ran to the car and started shooting it at the car, the car had caught on fire and the 4th injector was spewing gas. They had pinched an oring while installing the injector and never put the clips back on the injector rail to keep them in place. My husband could have been killed easily. The dealership never took ownership for it and blamed it on the dealership that sold us this the car. Every time we turn around it’s something else. The month of December we only had the car 6 days. It was in the shop 3 different. Times and everytime we got it back it wasn’t fixed. We bought this car in September and it had had 52 engine lights, over 10,000 in parts and labor to fix. Four rentals cars a new battery list goes on. We have tried numerous times to ask the dealership to make this right and their answer is for us to sell them the car back less our 20,000 deposit and buy a whole new car from them. That’s the solution we were given

Caught in stop and go traffic at night for 45 minutes. Car started moving forward even though my foot was only on the brake pedal. My first thought was I'd accidentally pressed both the brake and gas pedals, but I could see my foot on the brake pedal since the under-dash area is lit in the Premium model. It happened for about one minute the first time, then happened again a couple minutes later. I hit the bumper of a tour bus during the second instance at about two mph. The tour bus driver apparently didn't notice the hit and changed lanes a few minutes later. I didn't see any damage to the tour bus, but my license plate bracket and license plate were bent, and the middle part of my bumper didn't snap back together correctly. The Ford dealer was unable to duplicate the problem, and the brakes and vacuum pressure module didn't show any leaks. The service advisor said it was impossible for the transmission to engage without pressing the gas pedal, but I suspect the 10-speed transmission since the engine rpm didn't appear to change. There were no warning lights before or after the incident and the service advisor said no codes had been set. In retrospect I should have tried putting the transmission in neutral, used the emergency brake,or turned off the ignition (but a tractor trailer was about ten feet behind me).

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!

On July 26, 2021, I had a head on collision ( driver side to driver side ) where I felt like the vehicle didn’t want to stop. Even when I applied the brake, the vehicle kept going forward. In that collision, even though I was wearing my seatbelt, my head went straight up and I hit the top of my car. My head felt crunched into my neck and shoulders, and the belt restrained me enough to pull my right shoulder back and down from having my head crunching further into the top of my car. Although I wasn’t given a ticket for the accident, the Police found me to be at fault. Later, I went to an Urgent Care where they diagnosed me with having a concussion. I haven’t seen any other necessary doctors, because I don’t have the money out of pocket. I don’t know that my remaining PIP will cover anymore. I am still having issues with my head, neck, back, and hip now. I recently saw a Dentist and I may have TMJ. I never have experienced such pain of my entire left side of my face. My migraines have increased in frequency and intensity, and other health issues are agitated and inflamed.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2020 Ford Mustang Gt350r verdict →
