Engine

3 reports1 crash1 related recall
“Vehicle suffered sudden, total loss of motive power while driving. No dashboard warning lights or error codes were produced. Vehicle is currently grounded at Anderson Ford (SC) under active recall 26V547 / 26C40. Manufacturer and dealer are refusing alternative safe transportation, attempting to force the consumer to drive an unremedied, unsafe vehicle because the intermittent total-ground failure did not store a code."”

Electrical system

2 reports2 crashes1 related recall
“Recalls on 2024 Ford Mustangs: On 09/22/2026, at approximately 11:34AM, my Ford Mustang suffered a catastrophic malfunction. When I was braking on the offramp, the brakes did not engage and remained firm and unresponsive. The car immediately accelerated, despite my efforts on the brakes accompanied by the use of the emergency brake. The car continued to accelerate as I was trying to brake, navigating the terrain off the ramp on onto a grassy area. I maneuvered the car between two trees, trying in vain to use the brakes. The Mustang continued accelerating across 25a, until it hit a car on my passenger side, which spun me around- NO AIR BAGS DEPLOYED ! The car ended up going backwards hitting an i-beam that was supporting the street sign, bending it significantly. I hit my head on the side glass window.Thankfully, this stopped the propulsion of the runaway car and it finally came to a stop. Thank goodness I survived, as did everyone else in the vicinity of the malfunctioning out of control 2026 Ford Mustang.”

As of May 2026, Ford has already issued a major recall (Recall 25C69) for rollaway risks in other 2026 models like the Mustang Mach-E and Maverick due to a software fault in the "Integrated Park Module." While your gasoline Mustang (EcoBoost) was not explicitly named in that specific recall, it uses similar electronic shifting logic.”

Wheels

“On XXX I purchased a new 2026 Ford Mustang GT from the dealership at [XXX] and [XXX] in [XXX] 40 Hrs. after the purchase I was traveling on [XXX] Headed west at about 78 MPH the speed limit was 70 MPH., when my driver side rear tire let go, I mean totally blew out. The car slammed to the ground and the rear of the car slide to the right and almost flipped with me in it. I could have very well been killed. I don't know why this happened, but I clearly believe this to be a serious safety issue that needs to be dealt with by the dealership and Ford Motor corporation, next time someone may be killed. I have the tire and pictures of the tire if anyone needs them. I have contacted the dealership and has been speaking to executive Manager [XXX]. When I asked him about inspections and tire pressures before the car was delivered to me, he cut off all communications. I wrote them an official and signed statement by me concerning the incident.”
