The vehicle jolts when placed from park or reverse to Drive after being driven 30 or more minutes or driving 10+ miles. I had previously sent it to 3 different dealerships and only one was able to temporarily resolve the issue. They had to adjust the issue through a computer system. However, after 6-12 months, it is happening again. I feel that is a property or safety issue for drivers because, the transmission or shift change makes the vehicle jump forward and if not carefully could possibly hit another vehicle or person that passes through the front side of the vehicle.

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.

I have a 2018 Mustang GT with the 10R80 transmission. The transmission started giving me problems like slamming and slipping while shifting and sometimes jumping in and out of gear when drinking in the highway.The problem came from an engineering is with the CDF Drum... Ford has updated the CDF Drum and has fixed the problem. Ford never issues a recall to fix this problem with the vehicles produced with this issue but instead just used the updated production parts in the later models leaving the customers like myself to have to either pay out of pocket or rely on a warranty or after market warranty company to have this very expensive issue fixed. Right now as I am writing this, my car is in the transmission shop. Please help me. When I did a Google search of the CDF Drum issue, this is what was quoted: "The 2018 Ford Mustang GT with the 10R80 transmission can experience issues with the CDF (Clutch-Drum-Forward) drum, specifically with its bushing. This problem can lead to slippage, harsh shifting, and potential transmission failure. Ford has addressed this issue with design revisions to the CDF drum, including adding a lip to the bushing to prevent it from moving and causing fluid leaks."

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.

The contact stated that after the failure, he researched online and found a recall for rollaway failures however, the vehicle was not manufactured in the date range of the recalled vehicles. The contact referenced NHTSA Campaign Number: 18V213000 (Power Train) as the possible cause of the failure.

My 2018 Ford Mustang with Automatic Transmisson recently(Sept) started having issues with the gear shift being placed in Park, but the instrument panel is not illuminated in Park. If driver door is open, and keys removed, the chime may or may not sound. Research is showing same issue being reported and recalls were done due to missing roll pin that attaches the park pawl rod guide cup to the transmission case, and unseated transmission gear shift cable clip. If the parking brake is not applied, this could result in unintended vehicle movement, increasing the risk of injury or crash. The recalls only covered vehicles manufactured at a certain plant. However, my VIN # is not included in recalls. Due to safety concerns that my vehicle may lose Park function and roll away, causing damage/harm to others, I feel it should be included in the recall programs and repaired at no cost to me. I have not taken vehicle to Dealership at this point, as they will charge me $150 diagnostic fee.
