2018 Ford Explorer: shudder or vibration when accelerating

Filed Jun 19, 2026 · Transmission · IL

Vehicle: 2018 Ford Explorer Mileage at Failure: 62,212 miles On [XXX] while driving my 2018 Ford Explorer, the wrench warning light suddenly illuminated on the dashboard. At the same time, the vehicle experienced a significant loss of power and became extremely sluggish in acceleration. When I pressed the accelerator pedal, the vehicle failed to respond normally and did not accelerate as expected. This condition created a serious safety hazard because the vehicle could not maintain or increase speed when needed in traffic. Had this occurred while entering a highway, crossing an intersection, or attempting to avoid another vehicle, it could have resulted in a crash. The vehicle has been inspected by McCarthy Ford. The dealership diagnosed transmission-related problems and provided a repair estimate of $6,384.94. Ford Motor Company previously issued Customer Satisfaction Programs 20B27 and 20N07 for certain Ford Explorer vehicles equipped with the 6F35 transmission. Ford's own documentation acknowledges that transmission torque converter overheating may result in low performance, lack of acceleration during launch, sluggish vehicle operation, vibration, shuddering, and related transmission concerns. These symptoms are consistent with the condition experienced in my vehicle. I reported the issue to Ford Motor Company and sent a certified letter to CEO James D. Farley, Jr. requesting assistance and a policy adjustment due to the known transmission and torque converter concerns. To date, I have not received a satisfactory response. I am submitting this complaint because the sudden loss of acceleration and reduced vehicle power created a significant safety risk while operating the vehicle on public roadways.

Vehicle has lack of acceleration during launch, sluggish vehicle operation, and shudder/vibration while driving. Vehicle acceleration falters while attempting to merge onto a freeway creating dangerous driving conditions for myself and others on the freeway. Ford has issued a TSB and Customer Satisfaction Program (number 20N07) to cover the costs of essential repairs to the torque converter for this problem but Ford claims my vehicle is not covered by this TSB/CSP. This is despite the fact Ford confirms my vehicle was assembled at the same plant during the same time period as the rest of the vehicles covered by the TSB/CSP. Vehicle is available for inspection. Ford should be compelled to include my vehicle in this important safety program.

2018 Ford Explorer developed a shudder and rough idle, sluggish vehicle operation, slow acceleration during launch. No warning lamps. Researched issues online and found a bulletin from Ford Motor Company dated October 9, 2020 that identified the issue as a torque converter defect. My vehicle was manufactured during the identified time period and at the identified assembly plant but I did not receive a notice from Ford for the repair program. My vehicle has exhibited all of the known issues as well as a total loss of power while reversing leaving me sideways in the middle of the road while I had my family on a road trip risking collision and injury. Dealership confirms there was an issue but refuses to repair because my VIN was not listed in their system as affected. Feel the issue may extend to more vehicles than Ford previously figured.
