For roughly 4mths beginning in April 2025, my 2018 Ford Mustang ecoboost has been suffering from a sporadic misfire, with it the system reporting the misfire and the check engine light coming on, the Ford app identifying the misfire occurring. It was initially repaired with replacing all spark plugs, ignition leads. The sporadic misfire would continue to occur, Ford dealership kept the car for 2 days in late July, took everything apart said they were unable to replicate the misfire, cleared the codes (p0303 being the main one that appears consistently) and said to come back if it occurred again. Roughly 2 weeks later the issue occurred again, took the vehicle back to Ford where they kept the car for 2 days, went through the same process and could not replicate the issue. They dug deeper into the issue and found that the coolant would not hold pressure and with the use of a video scope found that the intake valve had fractured and was leaking coolant into the engine as well as distributing multiple shards and pieces of metal from the valve intake fracture. Informed me that the only option was to replace with a new engine and turboboost. They reviewed and found that there were no recalls related to this issue for this vehicle. After undertaking my own research, I found this to be a known issue for Ford and that roughly 100k vehicles had been recalled starting with the 2020 vehicles for the same issue. The out of pocket expense is around 14k, and the vehicle is currently waiting on a replacement engine to arrive. Currently Ford are not offering any assistance in the cost of the replacement, been though they have been servicing the car since 2020 and it is regularly maintained per their guidelines of vehicle needs based on the mileage driven.

On April 6th, the ac in the car began stalling and a few days after the engine started making all sorts of noise and failing and ultimately stopped working. I kept the car in my garage until I was able to obtain the money to replace the engine. I just yesterday picked up my car from the shop that replaced the engine (where I paid $13,000). The car is back in the shop and having same stalling issues.

While driving at highway speed it randomly shifts into first gear almost causing and accident/.

2018 Ford Mustang echo boost. Engine light came on code p0420 which is the catalytic converter and we already new this when bringing it into Ford dealership. We informed the check in advisor the transmission feels like it's slipping or jerks when in 2nd geer which slows down the vehicle. Took it to Ford and was first informed the transmission was good nothing wrong with it just need to change my catalytic converter because that was the code. We changed the catalytic converter but when driving still was experiencing the same thing we originally brought it in for which is the jerking and slowing down upon accelaration. Took it back to Ford they re checked it and said the cdf drum is failing and to repair it would cost $4000. I don't have $4000 and my vehicle is out of warranty because of the mileage.

Car jerking,rpm needle jumps alot,feel like im going to run into someone or something, not getting gas mileage like before.

My 2017 Ford Mustang gt has 27,000 mile on it. I was driving home from work and just went through a traffic circle and I was in 1gear when I went to shift I could not shift. The clutch blew apart while driving normal and it is the factory clutch. Pictures of the equipment involved are available and show no sign of wear or abuse just that it separated. This could have been a major is had I been on a major highway when it happened.

I was driving home from work at approximately 65mph when my transmission shifted and slammed back into gear. I stopped in a safe location, cut the car off and then back on, but the transmission is still slipping. The dealership was notified of powertrain, electrical, and oil consumption issues at three different service appointments, but the manufacturer has been no help at all. Had I not known what to do, this could have been a completely different scenario.

Unexpected downshift to first while driving between 40 mph to 65 mph can lead to complete loss of cruise control, accompanied by a wrench symbol and an error code. Additionally, the speedometer fails to display a reading and may abruptly drop to first gear without any prior warning. Signaling low fuel levels.

Weld at clutch pedal assembly broke, causing the clutch pedal to bind. This binding prevents the clutch pedal from fully depressing.

At idle the engine idles roughly and rotates randomly at speeds from 300 to 900 rpm. When starting from a stop such as a traffic light or when pulling onto a roadway hesitation is often noted and on several occasions this has resulted in near accidents as the vehicle won't proceed as required to move through an intersection.

Ford did issue a recall for several issues for my car, including but not limited to, problems when filling gas tank with evaporative purge system as well as cavitation of the fuel pump in high heat conditions, the doors not closing all the way or handles remaining open( not flush with rest of door) when door is shut, driver's side door trim/bezel around power window switch making buzzing sounds when stereo is in use, as well as ticking sounds coming from motor during operation and various creaks and sounds from front suspension when cornering and going over uneven terrain, and the transmission, the 5r55s, has the known hard shift into gear caused by bad servo. I have reached out to the dealers in my area regarding these issues and even though my car is the correct model and year for the service recall bulletins and has the exact issues described there in, I am told that the VIN on my car is not covered even though it is clearly suffering from equipment that exhibits all the same problems listed in the recall. I feel the responsibility to perform and pay for these repairs should fall on the manufacturer, not I, the customer.

While driving my 10r80 automatic transmission shifted into neutral even though the shifter was positioned in drive. I was unable to accelerate and was forced to pull over on the side of the road to prevent an accident from occurring. I placed the shifter into park and turned the car off. I then started the vehicle back up and began driving. The transmission continuously shifted rough while driving my destination.

After driving for 2 blocks, my car would not drive when hitting the gas pedal, the engine only reved. Unable to move the car in any gear, pedestrians helped push my car out of the middle of the road. Towed the car to a Ford dealership because the Ford app on my phone said "shift solenoid stuck in off position". Upon diagnosis the dealership said yes the solenoid is stuck in the off position but now the gears are slipping and you need a brand new transmission. This is the 10r80 automatic transmission that has had problems like this nationwide. I don't understand how this has not been recalled yet. With 63,000 miles a transmission should not be failing. There have been hundreds of documented cases of this specific transmission failing for countless reasons involving internal components.

The contact owns a 2018 Ford Mustang. The contact stated while the contact's wife was driving at an undisclosed speed, the contact noticed a grinding sound and the vehicle jerked.

The contact was also informed of technical service bulletin 10r80, which had a similar failure description, however the contact was informed that the repair was not covered under the program. In addition, the contact was informed that the failure was a known issue with Ford Mustangs. The contact was advised to contact the NHTSA hotline and report the failure. The failure mileage was approximately 44,113.

I was driving at 70mph and the steering wheel locked without any error showing on the dashboard. Ford could not find a fault when it was connected to a computer. Later after a test drive they confirmed it was the electronic power assisted gear assembly fault.

The weld that connects the clutch pedal bar to the tube it pivots in broke on my 2015 Mustang. This makes the pedal wobbly and can prevent the clutch from being fully depressed. For months, the clutch was squeaking. Upon inspection, I noticed the weld was broken. I have not been in an accident because of this, however, the clutch pedal is now loose and can at times hit the 'neutral' switch (which measures full depression of the clutch to allow the car to start), which prevents inconsistent depression of the clutch, leading to unsafe operation.

Transmission solenoid malfunction (p0757). Car came to an abrupt stop in the middle of a speeding boulevard for no external reason at all. There was no prior impact or damage. I almost got rear-ended and t-boned ten times. Considering the amount of complaints on this Ford transmission 10r80, I firmly believe this transmission needs to be recalled and our repair/damage expenses reimbursed. Thank you.

The contact owns a 2015 Ford Mustang. The contact stated while driving at approximately 45 mph the vehicle was shifting roughly. The contact stated that no warning light was illuminated. The contact stated that the failure was intermittent but became a recurring failure. The contact stated that the failure occurred at various speeds. The contact had taken the vehicle to a local dealer, where it was diagnosed and determined that the torque converter needed to be replaced. The vehicle was repaired. The manufacturer was informed of the failure. The contact researched online and related the failure to technical service bulletin number: 20b27 torque converter (power train). The failure mileage was approximately 130,000.

Related to regional recall 22r01, the rubber bumper on my brake pedal that engages the brake light switch failed and placed the vehicle in a low power mode. This failure occurred while merging onto the interstate and almost resulted in my being rear-ended by a semi truck. Having never been notified of this regional recall, I was able to verify this was the case after searching forums and youtube and identifying the pieces of the broken bumper in my floorboard. I find it to be horrendously unacceptable that this was allowed to be handled as a regional recall and no notice was ever produced, as it is a safety-related issue that could have resulted in grievous bodily harm. I am located in kentucky, which is not part of the named region.

Transmission seems to lose power while driving, the car will barely pull itself but the rpms increase if I accelerate. This has happened several times while driving and occasionally there are dash lights lighting and speedometer/gas gauge doesn’t work but that doesn’t happen every time. When it happens I pull over and shut it down and restart and it runs correctly until it happens again! I do a lot of highway driving and the car just “falling flat” on a multi-lane highway at 70+ mph is definitely a safety issue! I have taken it to my local fastlane shop and the car was driven but didn’t malfunction at that time. He advised me to try to drive it there if it happened again, but I have never been close to the shop at the times it happens or they are closed. There is no advance warning, it happens at various speeds and even on takeoff after stopping for traffic lights. I once was pulling into traffic when it happened and didn’t have enough power to get to my lane before it fell flat! fortunately I could back up before getting hit by oncoming traffic.

Yes, if the NHTSA communicates with me that they need to look at my transmission, and I am either provided another equal mode of transportation or paid for my lack of ability to use my vehicle during inspection/possession/out of service by the NHTSA. 10r80 10 speed transmission was finally replaced under warranty by Ford in January. The new transmission has been problematic and getting worse since March. Transmission flairs/slips. Transmission acts as if the brakes are put on at times/acceleration is greatly decreased for no reason. Hard shifts at times… I and other others are put at risk due my car, responds erratically and this could become a safety issue by causing a crash or loss of control by the Ford mach 1 Mustang. Transmission often is too high gear and the as a result, the engine is lugging too much. No idiot, lights or warning lights have come on this go round. The police have not inspected the transmission. I would not expect them or ask them to inspect the transmission because I would assume 99% of them would know very little to nothing about it. Same goes with the insurance company. Ford and chevy the two manufacturers of this transmission are both aware of the multiple problems of this poorly designed and manufactured transmission. I was not sure what incident date you wanted. The first transmission or second transmission? there are multiple incidents and issues starting from my first ownership of the car when I first test drove the car and had 550 miles on it. The original and replacement transmission are both and have been problematic and unsafe.

Recently started having erratic shifting issues. Will downshift randomly out of nowhere while driving. Sometimes will just be stuck in 1st gear and won’t go anywhere until I pull over and shut off/start up again. Dangerous because I never know when it will do it. Might seem like everything is fine and then all of a sudden, it downshifts and loses power. Rpm’s rise but car has no power. Have to figure out how to get out of the way. As stated in Ford’s “ customer satisfaction program 16n02,” my 2012 has all the symptoms and I have dtc code p0731 but dealer refused to service my vehicle because it doesn’t show up with my VIN, even though it’s a 2012 and I clearly need my molded leadframe replaced.
