The failure pattern owners describe
Owners of the 2021 Mustang Mach-E describe a cluster of software and hardware failures affecting steering, acceleration, and safety systems.
One-pedal drive mode unexpectedly disengages mid-drive—sometimes while braking or turning—forcing drivers to use friction brakes without warning. The system cannot be re-engaged without power-cycling the vehicle. Several owners report the vehicle surging forward when one-pedal mode fails, including incidents at traffic lights and during parking maneuvers.
A separate software defect causes drive modes to switch involuntarily, triggering a "Drive Mode Not Available" error on the instrument cluster. One owner nearly hit a concrete parking post when the vehicle accelerated during a mode switch. Owners also describe unintended acceleration during low-speed parking, garage entry, and while in reverse—with at least two incidents causing property damage and injuries.
Front camera faults appear frequently (some owners report them every few minutes), disabling adaptive cruise control, forward collision warning, pre-collision assist, lane centering, and automatic emergency braking. One owner's vehicle hard-braked on a narrow bridge when the fault triggered at highway speed, nearly causing a rear-end collision. Dealers have confirmed applicable technical bulletins but quoted repair costs up to $8,000 and offered only partial manufacturer discounts.
Cruise control itself occasionally accelerates to speeds 10–15 mph higher than set, and adaptive cruise accelerates toward lane-splitting motorcycles. One owner reported severe instrument cluster lag making the speedometer unreliable for over 10 seconds at a time, making cruise control unsafe to set.
Ford has issued technical bulletins and campaigns for the camera and one-pedal drive issues, but owners report fixes don't stick and safety features remain offline.

Failure modes owners describe
One-Pedal Drive Mode Unintended Disengagement
Software bug causes one-pedal drive (OPD) mode to disengage unexpectedly during operation. When OPD disengages, the vehicle stops regenerative braking and normal deceleration, forcing drivers to use friction brakes. The disengagement cannot be re-engaged without power-cycling the vehicle, creating sudden loss of expected vehicle behavior.
When: Intermittent; reported incidents include turning into parking spots, braking for left turns, and general driving
Symptoms owners cite: One-pedal drive mode suddenly disengages without driver input; Vehicle fails to slow down when foot lifted off accelerator after OPD disengagement; Driver receives notification on instrument cluster that OPD has been deactivated; Vehicle lurches forward as it shifts from OPD to standard drive mode; No re-engagement of OPD possible until vehicle is power-cycled
Drive Mode Switching with 'Drive Mode Not Available' Error and Unintended Acceleration
Software defect introduced by OTA update causes drive modes (Whisper, Engage, Unbridle) to change unexpectedly with 'Drive Mode Not Available' error displayed on screen. Error triggers unintended acceleration due to throttle response changes between modes. Also causes simultaneous one-pedal drive disengagement. Incident reports include parking maneuvers and normal driving.
When: Random, non-reproducible occurrences; one documented incident 11/8/2023
Symptoms owners cite: 'Drive Mode Not Available' error appears on main screen; Vehicle acceleration increases unexpectedly during deceleration input; Throttle response changes due to involuntary drive mode switching; One-pedal drive disengages at same time as error appears; Driver must slam brakes to avoid collision
Front Camera / Image Processing Module Failure Disabling ADAS
Front camera or Image Processing Module A (IPMA) fails intermittently or permanently, generating fault codes and disabling adaptive cruise control, Pre-Collision Assist, forward collision warning, and automatic emergency braking (AEB). Failures occur without physical damage, obstruction, or accident. Some failures resolve temporarily with software updates but recur within days or weeks. Dealer service confirms DTC U3000-49 and TSB 25-2156 / Campaign 11028164 applicability; Ford authorizes partial cost recovery only.
When: First reported August 2022 onwards; some complaints report March 2024 start; recurrent over months to years; one case at 80,029 miles
Symptoms owners cite: 'Front Camera Fault Service Required' warning message; 'Pre-Collision Assist Not Available' warning message; Adaptive cruise control disengages or becomes unavailable; Forward collision warning disabled; Pre-collision assist disabled; AEB unavailable; Lane centering and lane departure warning systems disabled; Hard braking occurs when fault activates during cruise control use
Codes mentioned: U3000-49
Repairs/costs cited: Module replacement quoted up to $8,000; Ford authorized 50% discount characterized as 'loyal customer discount' rather than warranty repair
Recalls/TSBs owners mention: TSB 25-2156 / NHTSA Campaign 11028164; Ford authorized partial cost recovery; software updates attempted but did not resolve recurrence
Instrument Cluster Lag and Display Freezing
Instrument cluster becomes unresponsive with severe lag in updating speedometer, turn signal indicators, and other display elements. Updates occur at intervals of 10 seconds or longer, making speed unknown to driver. Affects ability to set cruise control safely. Lighting indicators update slowly while audible signals function normally.
When: Reported after 9+ hour vehicle idle; one incident documented
Symptoms owners cite: Instrument cluster display frozen or severely lagged; Speedometer updates delayed by 10 seconds or more; Turn signal indicator refreshes slowly despite normal audible click; Unable to determine current vehicle speed reliably; Cruise control speed setting unclear due to display lag; Unable to determine if adaptive systems functioning due to unresponsive display
Unintended Acceleration During Parking and Low-Speed Maneuvers
Vehicle unexpectedly accelerates forward during parking or low-speed driving maneuvers (entering garage, exiting parking spot, reversing from parking space, parking lot entry) with no driver input. Occurs at very low speeds (under 20 mph). No warning lights reported in some cases. Accidents and property damage documented. Advanced emergency braking did not activate in at least one incident.
When: Documented incidents: ~2,335 miles (entering garage); 14,750 miles (reversing from parking space); March 20, 2022 (parking on driveway); multiple incidents reported within one week at unspecified mileage
Symptoms owners cite: Sudden forward acceleration with no accelerator input; Unintended acceleration during slow parking maneuvers; Vehicle accelerates into obstacles, parked vehicles, or structures; No warning lights illuminated (in some cases); AEB does not deploy when unintended acceleration occurs
Repairs/costs cited: Property damage and vehicle damage documented; insurance claims filed
Recalls/TSBs owners mention: Case number provided to owner; no recall found on VIN at time of report; manufacturer advised contact
Unintended Acceleration in One-Pedal Drive Mode
Vehicle surges or accelerates forward unexpectedly while operating in one-pedal drive mode, including while braking or at standstill. Occurs in modes such as Unbridle and during standard one-pedal operation. Incidents result in rear-end collisions and vehicle strikes.
When: Various incidents: while stopped at stoplight (Unbridle mode with OPD); while decelerating in OPD mode; intermittent occurrences within one week reported (4-6 times when exiting parking or driveway)
Symptoms owners cite: Vehicle surges or accelerates forward while in OPD mode; Unintended acceleration while stopped at traffic light; Unintended acceleration while decelerating in OPD; Rear-end collision of another vehicle; Pre-collision warning activates after unintended acceleration begins
Cruise Control Unintended Acceleration and Sudden Speed Increase
Vehicle accelerates to a higher speed than set while in cruise control, occurring both during sustained cruising and after resuming cruise control following a stop. Speed jumps of 10+ mph above set speed reported (e.g., 38 mph set jumps to 50 mph; 55 mph set jumps to 70 mph). Issue began approximately 3 weeks prior to complaint in one case.
When: Intermittent; began ~3 weeks before complaint in one case; occurs during cruising or after resuming cruise from stopped state
Symptoms owners cite: Cruise control suddenly accelerates vehicle to higher speed than set; Speed increases 10-15 mph above set cruise speed; Unintended acceleration occurs both during cruise and after cruise resumption; No driver input on accelerator
Adaptive Cruise Control Acceleration Toward Slowing Vehicle During Lane Splitting
Adaptive cruise control accelerates vehicle toward a motorcycle lane splitting to the right, causing the vehicle to accelerate toward a slowing or stopped vehicle ahead. System fails to recognize motorcycle or does not properly adjust for close vehicles entering the cruise control vehicle's path.
When: Reported during active adaptive cruise control use
Symptoms owners cite: Adaptive cruise control accelerates when motorcycle lane splits to vehicle's right; Vehicle accelerates toward slowing or stopped vehicle ahead; Unintended acceleration toward other traffic
