   Experiencing total stop of acceleration in two occasions: 1) when putting the car in reverse and pressing the accelerator and 2) when making a left or right turn after a yield or stop. And when I say loss of acceleration, I don’t mean hesitation, reduced power, or sluggish acceleration. I mean absolutely ZERO acceleration. I’ll press the accelerator and nothing happens. The engine stays basically at idle, and the truck will not accelerate for roughly 5-10 seconds, regardless…

   I am filing a safety complaint regarding a recurring, hazardous transmission failure during highway and incline driving (specifically experienced on mountain highway passes in Arkansas). While driving at highway speeds on uphill inclines, the transmission severely hesitates and struggles to downshift under load. When it finally engages, it violently slams into gear. During these episodes, the truck experiences a sudden loss of motive power and acceleration lag, accompanied…

   I am reporting a safety-related transmission problem I experienced with my 2021 Ford F-150 equipped with the 10R80 automatic transmission. While driving normally, the transmission suddenly shifts hard/lags on gears 3-5 and sometime higher gears 7-9 at higher speeds. I’ve also noticed a buzzing/metallic rattling coming near the engine from inside. There is also times i can tell i have no power when trying to speed up and the other day i almost thought i was going to get…

   Ive noticed that the electric motor sometimes doesnt want to disengage quickly when I step on the brakes. In this incident I had to make a hard brake because someone pulled out in front of me. I had the cruise control on. When I slammed on the brakes the vehicle did not stop fast the vehicle felt as if it was still being pushed by something. Then a small jolt was felt and then the vehicle finally slowed. Had I been going faster or had the car that pulled been closer. This…

   I am reporting a safety-related transmission problem I experienced with my 2021 Ford F-150 equipped with the 10R80 automatic transmission. While driving normally, the transmission suddenly has lost propulsion and RPMs flare while driving steadily uphill. This occurred while merging onto a fast moving highway and while traveling at a steady speed going uphill, creating a potentially dangerous situation because the truck did not respond as expected when I needed predictable…

7. Filed Aug 1, 2026TNTransmission & Drivetrain

   I'm reporting a transmission problem on my 2021 Ford F-150 with the 10R80 automatic transmission that I believe is a safety issue, not just a reliability one. The truck currently has about 55,000 miles on it. Right now the truck shifts hard and jerks every time I drive it, and it's especially bad at low speed. The worst situation is creeping through a parking lot looking for a spot, the transmission drops down into first with a clunk and a jerk, and then kicks again when it…

   I am reporting a safety-related transmission problem I experienced with my 2021 Ford F-150 equipped with the 10R80 automatic transmission. While driving normally, the transmission suddenly slipped at least twice, and shifts violently often. The truck while driving on a 35mph road after just going over a railroad track I went to accelerate and lost gear and the transmission slipped really bad and violently caught a gear after reaching around 4000 rpm. The truck also shifts…

    When starting from a stop or rolling slowly under 15 mph, pressing the accelerator pedal — even flooring it — produces no engine or motor response for 1–3 seconds. The vehicle then suddenly accelerates. This occurs intermittently on both electric and gas power. Safety concern because it delays merging or pulling out into traffic.

12. Filed Apr 2, 2026CTEngineFuel, Hybrid & EV PropulsionTransmission & Drivetrain

    Several times, the vehicle has failed to accelerate or respond to accellerator pedal input for several seconds. It seems to happen when switching from electric to hybrid modes, and when shifting between lower gears simultaneously. Once the switch to hybrid occurs the engine will rev high with some acceleration even if the accelerator pedal is no longer being pressed. This acceleration has happened when I had my foot over the brake pedal in anticipation of pulling over to…
