I was driving in town going about 20 MPH when I approached and intersection and stepped on the brakes. The brakes locked up, multiple warning lights, messages, audible alarms went off. I though the truck died and I put it in park and turned off the key. Then I turned the key back on, all the lights and warnings came back on, but it also said ready to drive. I was not able to accelerate using the gas pedal, truck was moving slowly on its own, it gained some speed but only ran on the electric motor. No gas engine. I got 3 blocks to my destination very slowly and shut the truck off. I had to go inside to do some work and when I came back about an hour later I turned the truck on and all the alerts were gone except the check engine light. It did run normal then. After calling the dealership they said to bring it in so they could look at it. I left it there and they called later saying they had pulled multiple error codes, did not tell me what they were, they cleared all the codes and drove it and said it did not act up for them and said I could come pick it up. I do not want to drive it because I feel like this could happen again at any time and if I were driving at a higher speed or on a interstate and this happened who knows who could have been hurt. This Maverick is my daily driver for work ect. but I will not drive it unless I absolutely have to right now. I got no answers from the dealership. Before this, no warning lights had been on.

Driving at 65mph and the vehicle began to lose power. Messages displayed on instrument cluster "Service engine soon" "Pre-Collision Asist not available" "Power train malfunction/reduced power" vehicle started losing power and was unable to maintain speed. Check engine light appeared as this was occurring. This occurred in traffic and other drivers did not expect this. I was able to pull over to the side of the road and shut the vehicle down. Once I started the truck again the check engine light remained on but I was able to accelerate back to 60mph.

I was driving [XXX] on [XXX] around [XXX] yesterday morning north . Without warning I lost control of the accelerator and the speed diminished to around 35 MPH. Several warning lights flashed onto the dashboard saying systems were failing. Check engine light came on and a "wrench" symbol appeared. The light on the transition control dial for "D" started flashing. I was in a construction area with no shoulder when it happened. I was able to creep into a niche on a partial turnoff around .5 miles later. I shut the car off and restarted it. Same problems. I noticed I was .25 miles from an exit and waited for traffic to clear from behind. Managed to get to 10-15 MPH and up the exit with traffic blaring around me. Parked at a McDonald's and wait for a tow truck that never came after 2.5 hours. Made an appointment with nice folks at Classic Ford in Columbia. I was told tow truck might be another 2.5 hours so I tried to restart car. This time only the "check engine" light stayed on. I drove the car slowly in electric mode around the parking lot and it seemed safe at lower speeds. I mapped out a "less the 45 MPH" route to Classic Ford and was able to reach there without further incident. However, the "check engine" light remained on the entire trip. The car is now being checked by Classic Ford. I have had no diagnosis yet. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The dashboard cluster had all the lights come on check engine, abs ect light up and I had limit power 5mph enough to get my to the side of the freeway and all of a sudden the brake engaged and the truck jolted to a stop. I took the truck back to the dealer and they uploaded the system update again and released the truck back to me and a couple of days later the same thing happened.

Was driving on the freeway and a ton of warnings suddenly appeared on the dash. Pre-collision assist not available, stop driving now, service engine soon, powertrain malfunction, etc. The truck would not accelerate when the gas pedal was pressed and slowly slowed down. The truck would auto-accelerate (without gas pedal input) to about 20 mph unless the brake was applied (limp-mode). I pulled over, disconnected the 12V battery and reconnected which seemed to fix the problem. The dealership could not figure out the issue. I believe that the 12V battery was somehow drained to a point where it fed a low-voltage to suite of safety sensors which all went haywire.

Driving at highway speeds, the vehicle started de-accelerating with a message on the dash saying to slow down to shift in selected gear. The vehicle did not respond to any accelerating to avoid traffic to get to the side of the road and only deaccelerated. The "D" indicator in the PRNDL was flashing as i pulled off to the side of the road. Once stopped, error messages appeared on the dash; "Hill Start Assist Not Available," "Service AdvanceTrac," "Pre-Colision Assist Not Available," and "Service Vehicle Soon." After waiting 5-7 minutes with the vehicle turned off, The vehicle was again drivable with the CEL illuminated. This issue generated two codes: U1011 - The automobile fault code U1011 indicates a problem with the Controller Area Network (CAN) communication harness, a faulty Engine Control Module (ECM), or a poor harness ground connection. The most common symptom is the Engine Light ON or Service Engine Soon Warning Light. U1028 - The automobile fault code U1028 indicates a communication issue between the vehicle’s modules. This is often accompanied by the engine light turning on. The cause of this fault code could be a faulty module, an open or shorted module harness, or a poor electrical connection in the module circuit.

1RQ24014 · Loss Of Motive Power
Opened Nov 15, 2024 · Closed Oct 10, 2025
Status: closed (inferred from source dates) · Electrical SYSTEM:12V/24V/48V Battery
On January 31, 2024, The Office of Defects Investigation (ODI) opened a Preliminary Evaluation (PE24002) to investigate loss of motive power allegations in model year (MY) 2021 Ford Bronco Sport vehicles. Consumers reported a loss of engine power accompanied by complete electrical system failure either while driving or after stopping at a traffic light or stop sign. The vehicles generally could not be restarted, and the incidents were commonly diagnosed by dealerships to a failed 12-Volt (12V) battery. On April 12, 2024, Ford issued safety recall 24V-267 covering 456,565 MY 2021-2024 Ford Bronco Sport and MY 2022-2023 Ford Maverick vehicles. The recall addressed loss of motive power resulting from sudden degradation of the 12V battery during the drive cycle. The recall remedy consisted of software updates to the body control module and the powertrain control module. The updated software aimed to provide warning to consumers when the battery is failing and inhibit certain vehicle functions which can lead to loss of motive power incidents. Additionally, Ford removed the existing 12V Enhanced Flooded Battery (EFB) as both a service component for the subject vehicles and original equipment for newly built Bronco Sport vehicles (during MY 2024 production), replacing it with a more robust absorbed glass mat (AGM) battery. The same AGM battery had been incorporated into Ford Maverick production in late 2022. Following recall 24V-267, ODI received loss of motive power complaints in vehicles that had previously received Ford’s software-based remedy. Consumers reported that they did not receive warnings related to the 12V battery or the vehicle’s electrical system before the loss of power. On November 15, 2024, ODI opened Recall Query (RQ24014) to assess the effectiveness of the 24V-267 recall remedy. On January 19, 2025, Ford issued recall 25V-019 covering 272,817 MY 2021-2023 Bronco Sport and MY 2022-2023 Ford Maverick vehicles. The new recall addressed the same hazard as 24V-267 but required replacement of the existing 12V battery with an AGM battery as the remedy. Ford reported that following the opening of RQ24014, it evaluated several field-returned 12V batteries, and determined that EFBs produced by battery supplier Camel potentially contained internal manufacturing defects causing loss of motive power. Ford further concluded that the software updates provided in the 24V-267 recall remedy were unable to detect battery failures quickly enough to avoid loss of motive power. Vehicles previously within the scope of recall 24V-267, but outside of the scope of recall 25V-019, are equipped with EFBs produced by a different battery supplier (Clarios). When recall 25V-019 was issued, Ford had not identified any Clarios EFBs exhibiting the same failure mode as the Camel EFBs. In light of Ford’s recall action, ODI is closing this Recall Query. The agency will continue to monitor loss of motive power complaints in Bronco Sport vehicles equipped with Clarios EFBs and reserves the right to take additional action if warranted by future circumstances.
