2020 Ford Mustang: jerking or lurching

Filed Apr 28, 2026 · Engine, Transmission · IN

IMRC actuator rod broke causing the air/fuel mix to be sporadic. Creating a misfire on random cylinders. Major loss of power and very jerky motions, causing the vehicle to loose control. Luckily it was on an open spacious road. Unfortunately this has been an ongoing problem and there is nobody selling updated parts the electronics will recognize and very difficult to find oe replacement parts, real costly. And may fix the issue for a short period of time. I have a brand new manifold off of a same totaled mustang since Dec 2025 and the same part broke.

I had parked my car in a spot at an office building. As I was about to put the vehicle in park it lurched forward going over a standard curb across a sidewalk and then into the brick wall of the building. The air bag did not deploy. The car lurched about ten feet total before hitting the wall.

Description of the issue: The transmission has a recurring problem with shifting. When placing the vehicle into Reverse, it engages with a harsh and sudden jerk. When shifting from Reverse to Drive, there is a noticeable delay in engagement before the vehicle responds. These problems occur under normal operating conditions and are repeatable. Safety risk: This creates a significant safety hazard. The harsh jerking when shifting into Reverse can cause unintended movement, risking collisions or injury. The delayed engagement when shifting into Drive leaves the driver vulnerable in traffic situations (such as backing out of parking spaces or entering traffic), increasing the chance of an accident. Inspection/confirmation: The issue has been reproduced and confirmed by the dealership. However, it has not been permanently resolved. Ford has issued a Technical Service Bulletin (TSB) addressing this known transmission problem through a software update. Manufacturer/dealer involvement: When the vehicle was already connected to Ford’s diagnostic system for a Body Control Module recall, the dealer refused to apply the available TSB update for the transmission without charging an additional $280 “diagnostic” fee. This was despite the fact that Ford has officially acknowledged the issue and issued a TSB to address it. No permanent fix has been provided. Availability for inspection: The vehicle and transmission are available for inspection upon request.

The transmission takes over when shifting from first gear. This is a automatic 10 speed that when first driven after setting overnight slips out of first and the engine revs on its own (foot removed from gas pedal) to between 4 and 6 thousand then slams into the next gear. This lurches the vehicle ahead and slams the rear pinion. trying to stop the car is difficult when it revs so high then slams into gear. This also happened in a full parking lot and could have lurched into people. I have had it at the ford dealer several times to fix, The first dealer rode with me and replicated the issue. The first dealer reached out to ford engineers and they suggested replacing the valve body in the transmission. (it was worse after the valve body change) The dealer told me they did change the valve body but there is no warranty information showing that. I have been without my car total of 5 weeks so far and they continue to tell me they cant replicate it. I have it on video and it does it almost daily when I drive it. I will not let my spouse drive the car because of this safety issue. This is the same issue that the f150 had in 2020.
