2018 Ford Mustang

The contact owns a 2018 Ford Mustang. The contact stated that while driving at 65 MPH, the message "Front Passenger Door Ajar" was displayed on the instrument panel. The contact pulled over to the side of the road and opened and closed the door. The contact stated that the failure persisted. The message was displayed three times. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was notified of the failure. The failure mileage was unknown.

There is a coolant intrusion on my vehicle, which resulted in either cracking the engine block or head gasket. In turn, this has caused a costly repair on a car with only 56,000 miles on it. Ford is aware of the issues with these engines and the seals on them. It’s a 2018 Ecoboost! It also happened to my mom’s Ecoboost around the same mileage. This isn’t normal and Ford is literally turning a blind eye to a very serious issue which results in total engine failure. On top of that the repair for this issue is costing $12,000 to repair at the dealership. This is absolutely absurd for a company as big as Ford, to build a faulty engine and then not offer any support/recalls to help all of those affected by it, including me.

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.

My engine began experiencing misfires at around 40,000 miles. They were on and off. The check engine light would pop up and go away for around a month. Then the vehicle began having a rough start and check engine light would not go away. I sent the vehicle back to the dealer where they determined that my engine was having misfires due to a coolant leak into cylinder one, stemming from a poor engine design. The engine needed to be replaced. The repair was covered under my warranty.

Over the past year, we've had this car into the Ford of Clermont Florida dealer 5 times about a leak. Whenever we have a storm, the back footwell fills with water. Their leak specialist has said he has found the source of the issue multiple times and after each "repair", we still have a leak. They've replaced the rubber around both side windows and they've asked us to have the front windshield replaced. Even with all of this work, we still have a leak. In the longer term, this could compromise the structural integrity of the car. I don't know what else to do beyond bringing the car back again. I am listing [XXX] as the date the "incident occurred" because this is the latest water breach. But, it's been happening over the past year.

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.

While parked all day with the ignition off and lights off, I returned to find the brake lights and third brake light illuminated. The lights stayed on even after moving the brake pedal. I discovered a small broken plastic bumper on the floorboard, which appears to be the brake pedal stop bumper associated with recall 22V011. This failure causes the brake light circuit to remain closed, leaving the brake lamps on continuously, potentially confusing other drivers and draining the battery. No crash occurred.

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."
