2020 Ford Mustang

1. 2020 Mustang Ecoboost is equipped from factory with redesigned block to minimize/eliminate coolant intrusion and or head gasket failure. I still had the dreaded "ecoboom" issue with coolant intrusion on two cylinders as a result of a broken head gasket and poor engine block design. Regular maintenance was perfomed and use primarily Top Tier 93 octane fuel. 5K mile interval 5W-50 oil changes according to manual using Ford spec oil full synthetic. Cold Start Misfires and excessive engine shaking are still occurring despite short block replacement by Ford and they won't diagnose properly. 2. Electrical/Audio. Issue with crackling audio, audio skipping and both iPhones and Androids having disconnection issues. Factory reset the Sync module twice, attempted reset by unplugging car battery and also checked alternator. Replaced car battery with fresh battery and issue persists. 3. Powertrain: The 10R80 Auto Transmission is extremely jarring and does not shift smoothly. Hesitates throughout gears, sluggish gears changes. Gives whiplash effect even after a filter and oil change for the transmission with OEM fluid and filter. Premature Transmission gasket housing failure as well causing ATF to leak onto ground.

The back up camera periodically has a black screen or a blue screen. The sound of an object getting closer some times works and sometimes doesn't. Also the lines showing where the tires are on the camera do not appear either. Transmission was replaced under warranty for several issues. It's the 10 speed version. However even with the new transmission. It tends to lag on gear 4 mainly.

Transmission Issue. Transmission slams into 2nd gear when downshifting from 3rd. Transmission has grinding noise when going from 4th to 5th. Potential safety issue due to potential transmission failure. Yes, problem is reproducible, however, it is awaiting inspection at Mike Patton Ford. No warning lamps. Car has had transmission issues intermittently since 4/2020. This issue started 2 weeks ago.

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.

Transmission issue. Transmission is leaking fluid. Vehicle is currently at my home waiting to go to dealership during normal business hours. Car started smoking and running hot while getting off the interstate. I was in a travel lane when this happened. Huge safety risk. Fire department was called to ensure there was not a fire that started. Car was towed to my home until it can be towed to a dealer during working hours. General vehicle inspection done by fire department to ensure there was not a fire. They advised the car not be driven until it has been inspected by Ford. No warnings or indications there was a problem other than the smoke billowing from the engine.

Intermittent loss of throttle with wrench light. Engine goes into derate, have to shut off car, let sit for 3-5 minutes, restart then ok until it occurs again. Loss of throttle at any time is unsafe. Two Ford dealers have tried to repair with no luck. They have replaced the throttle pedal assembly, the throttle body, and now the PCM. Problem is still present. Have an ongoing Ford customer service case #CAS44568044-D6G8F8. Still awaiting resolution. Vehicle is still under 3/36 Base warranty. Problem has been ongoing for a little over a year now.

The contact owns a 2020 Ford Mustang. The contact state that the while driving at an undisclosed speed and making a right turn, the vehicle failed to shift into 2nd gear and stalled. No warning lights were illuminated. The contact stated that upon inspecting under the hood of the vehicle, he noticed that the clutch fluid line had shifted back and forth causing the failure. Additionally, the contact stated that he smelled a burning fuel odor inside the engine. The contact stated that he was able to restart the vehicle and drove the vehicle in 1st gear. The vehicle was not diagnosed or repaired. Neither the dealer nor the manufacturer was notified of the failure. The failure mileage was approximately 18,923.

The transmission takes over when shifting from first gear. This is a automatic 10 speed that when first driven after setting overnight slips out of first and the engine revs on its own (foot removed from gas pedal) to between 4 and 6 thousand then slams into the next gear. This lurches the vehicle ahead and slams the rear pinion. trying to stop the car is difficult when it revs so high then slams into gear. This also happened in a full parking lot and could have lurched into people. I have had it at the ford dealer several times to fix, The first dealer rode with me and replicated the issue. The first dealer reached out to ford engineers and they suggested replacing the valve body in the transmission. (it was worse after the valve body change) The dealer told me they did change the valve body but there is no warranty information showing that. I have been without my car total of 5 weeks so far and they continue to tell me they cant replicate it. I have it on video and it does it almost daily when I drive it. I will not let my spouse drive the car because of this safety issue. This is the same issue that the f150 had in 2020.

The contact owns a 2020 Ford Mustang. The contact stated that the reverse light, the rearview camera, the Cross Traffic System, the blind spot detector, the Lane Assist System, and other unknown features had ceased to work. The contact received notification of NHTSA Campaign Number: 22V382000 (Power Train) and the vehicle was taken to the dealer for the recall repair; however, the failure persisted after the repair. The check engine warning light was illuminated and a message advising to check the Owner's Manual was displayed. The contact stated that the recall remedy failed to fix the failures. The dealer was notified of the failure and submitted a case report to the manufacturer; however, the manufacturer declined to cover the repair. The vehicle was not repaired. The failure mileage was approximately 2,700.
