2018 FORD MUSTANG Complaints

Coolant leaking in 3rd cylinder causing engine misfires. The vehicle has less than 50K miles on it and shouldn't be having these issues. The shop quoted nearly $5,000 to fix. Many other mustang owners are having this same issue.

Ecoboost 4 Turbo engine has a known design flaw - coolant channels were placed between cylinders that don't allow them to seal properly and this leaks coolant into the engine eventually causing engine failure. FORD corrected this defect in 2020 but never let customers know. I now have a 5 year old car in immaculate condition that needs a new engine. It doesn't start reliably and I have lost power while driving a few times. I've already spent $1600 on repairs only to find out the issue was the engine and a KNOWN issue that Ford covered up. If I want to repair my car I am responsible for 5K in engine repair. Ford needs to be held liable for this and they should be responsible for replacing my engine.

While traveling about 70 to 75 mph the passenger side door unlatched and several minutes later the driver side door unlocked the door is a jar alert showed on the dashboard this happened twice

The contact owns a 2018 Ford Mustang. The contact stated that the vehicle was shaking at start up. There was no warning light illuminated. The contact had taken the vehicle to an independent mechanic who informed him that coolant had leaked into cylinder #3, causing the engine to overheat and caused engine damage. The contact took the vehicle to a dealer who confirmed the failure and replaced cylinder heads on all four cylinders. The manufacturer was notified of the failure. The failure mileage was approximately 65,000.

When shifting into drive from reverse there's a two to 3 second delay and when it does go into drive it jerks foward

The contact owns a 2018 Ford Mustang. The contact stated that while parked, he attempted to access the trunk of the vehicle, and upon depressing the trunk release, he heard clicking, but the trunk failed to open. Upon investigation, the contact noticed that the trunk appeared stuck or jammed, with no external damages observed. A month prior to the trunk malfunction, the contact noticed unspecified video feed issues with the rearview camera. No warning lights were illuminated. The vehicle was taken to a Ford dealer, who diagnosed a malfunctioning body wiring harness in the trunk and related the malfunction to the rearview camera failure. The vehicle was not repaired. The manufacturer was notified of the failure, and a case was opened. The failure mileage was 81,000.

The parking brakes do not engage or release, perpetually stuck in-between (half-engaged). The handle inside the car can travel all the way to the top, but brakes do not engage enough to keep the car from rolling down my driveway without a brick under the tire. Upon inspection, it is obvious that the lever that controls the brakes does not release on either rear caliper (it only moves up - to the fully engaged position, but does not release). This began happening in 2019, but considered it normal wear. In 2021, the car started rolling back on hills. Ford was not helpful with the issue. I followed a service guide for adjusting the tension on the cable. This improved the situation until early 2023. Now, all of the adjustments are at max and the parking brake is inoperable. As Ford was previously unwilling to help, I'm hoping NHTSA can assist. Parking brakes should not fail after 1 year. They are not a wear item.

2018 Ford Mustang with 10R80 10 speed transmission. Bronco like action when slowing almost whiplash like , stalls when stopping sometime, very hard shift jerking, hard downshifting when slowing, clunking into reverse, loss of power suddenly on the FREEWAY!!!!!!!!!, very hot transmission temperatures (230+), limp mode, Very unsafe if in any FORD or other vehicles have the 10R80.
