2018 Ford Escape: shudder or vibration when accelerating

Filed Oct 13, 2026 · Engine, Transmission · VA

My daughter was driving our 2018 Ford Escape at highway speed when it suddenly began shaking and shuddering violently, with no advance warning. The check engine light came on for the first time as the shaking began. The vehicle lost propulsion, and the shaking impaired her ability to control it, creating an immediate safety emergency in moving highway traffic. She had to maneuver quickly out of traffic onto a narrow shoulder. It was dark, and the limited shoulder space made exiting safely difficult. She feared for her life due to the sudden failure and exposure to passing traffic. She reached the shoulder without a collision. The vehicle required an emergency tow through her insurance company, and she received transportation home. The vehicle had undergone a safety inspection in August before this incident. A Ford dealership confirmed an internal engine leak allowing coolant into a cylinder's combustion chamber. A borescope inspection found liquid on top of the piston, and a cooling-system pressure test confirmed coolant entering the combustion chamber. The spark plugs were severely carbon-fouled, causing a misfire. Replacing them temporarily improved the symptoms, but the misfire quickly returned. The dealership determined that the engine requires a rebuild or replacement. The diagnosis appears to correspond to Ford Customer Satisfaction Program 21N12, dated June 9, 2022. We were not notified of this issue before the incident and found no corresponding safety recall for this vehicle in the federal safety agency's records. This sudden failure caused loss of propulsion and impaired control at highway speed, forcing an emergency maneuver onto a narrow shoulder after dark. The check engine light provided no advance warning. We request that the federal safety agency investigate this defect and determine whether a safety recall is warranted to prevent similar incidents and injuries.

Ford Escape has experienced coolant intrusion into the engine cylinders, a known issue affecting this model year. The vehicle began misfiring and consuming coolant without external leaks. The dealership confirmed a Technical Service Bulletin applies to my VIN. This defect can cause engine failure while driving, creating a serious safety risk. The engine shudders so bad I cannot drive the car. I have also had to replace the transmission a few years back. It became a safety hazard. I was driving it and it wouldn't get up to speed and it was stalling on the road with traffic. This vehicle has several know issues, the cost to upkeep and constantly replace things to maintain safety is unaffordable for anyone. Children and people ride in these cars. These cars are unsafe to be on the road for those in them and around them. I still owe money on mine and can't even drive it due to its safety hazards with the engine and the coolant intrusion. I do not have a repair invoice as I decided to not drop anymore money into this car. Its unfortunate I am still paying on the loan for it.

While driving my car my check engine light started blinking and then went solid. I went to get the codes checked and they had originally thought it was something with the spark plug. After driving the car around a little longer the check engine light started to blink and then my engine would not allow me to go over 25 miles without shuddering violently. I took my car into a local dealership where I bought it and they checked everything over and found out that the coolant was leaking into the engine and certain cylinders. The mechanic told me that this is apparently a common problem with this car however he told me there was no recall at the time that allowed for my car to be repaired by ford. Had I not stopped driving my car and got it towed to the dealership there's a very good chance I could have been injured due to serious engine malfunction. The fact that Ford is not picking up this tab is absolutely absurd.
