While driving, the car severely jerked and all the lights on the dash lit up. I received the errors “Powertrain failure”, “vehicle in low gear mode”, “pre collision assist not available” and “service engine soon”. I quickly lost all power and was completely unable to accelerate. I happened to be going down hill so I coasted to a clear area where I could safely stop. After coming to a stop the car could not move forward and needed to be towed. I have not received any errors prior to this. However, I did recently complete a recall that involved a powertrain software update.

While traveling on the highway at approximately 75mph the instrument cluster began to flash warnings, (Selected gear will be changed to when speed slows down, precollision assist not available, service engine soon) the accelerator pedal was unresponsive, and the vehicle began to slow. I parked the vehicle, shut the engine off, and restarted. upon restarting the vehicle would only move at approximately 10mph, the accelerator pedal was still unresponsive. I then parked the vehicle and called for a tow truck to take the vehicle to the dealership.

Vehicle had a sudden loss of power at ~40mph and began rapidly decelerating. Had there been a car behind me, the sudden deceleration could have caused a collision. Warning lamps and messages displayed on the instrument cluster instantly. I pulled the OBD codes and received U1011 and U1028 as active codes. These codes indicate a PCM software issue. It is important to note that this issue occurred after a PCM software update was performed as part of a recall. I power cycled the vehicle, cleared the DTC codes, and after multiple attempts, the vehicle worked normally again and I was able to drive it home. I have been unable to recreate the problem after clearing the codes. Prior to this incident, I have not had any problems from the vehicle. I suspect the the PCM software recall is what caused the problem.

Yes, I was driving around 75 mph [XXX] in Thousand Oaks, Ca and I lost power to the engine. No acceleration from the gas pedal. Was able to turn hazards on and make it off freeway. This issue now has happened over 5 times at all speeds. Truck is currently with Ford. Also this issue never happened until Ford fixed the CV axles that went bad. First time it lost power was the night I picked up from dealership from them fixing cv axles. They also did some recall updates with codes. I can say this is a very dangerous situation when losing power driving on a California freeway. Not having my truck is also causing me many issues with work and clients. The truck is my lifeline.

Today I was driving on the highway when the precollision alert came on with no vehicles in front of me. About 5 minutes later I received a series of error messages and the vehicle went into a limo mode where it automatically drove at 20 MPH with no accelerator input from the driver. The following errors popped up on my screen. Check engine light Power train light (wrench)/reduced power Brake light pre-collision light/pre-collision unavailable Hill assist message Will engage in gear selected at low speed. Pulled over, shut it off, turned it back on, put in drive and it started accelerating on its own but only up to about 20mph, stopped and shut it off again. Turned back on and all the messages and light disappeared except check engine light remained on.

Just had a recall completed related to software programming in the past 3 weeks. Since then this has occured twice. While driving at highway speeds the vehicle quickly lost/reduced power and slowed down to 20 mph and produced a message that stated " Powertrain malfunction/Reduced power, engine service soon, and precollision assistance not available". This caused me to almost be rear ended and get into an accident with other vehicles on the road. It likely would have resulted in an accident/injury if not for light traffic that day. Ford has stated they cannot reproduce the issue.

The dealer said a hybrid part that transfers power failed. I was starting from a stoplight at a busy intersection and lost power and a warning popped up saying to turn my engine off immediately, luckily I was able to coast into a gas station. If I was on the highway it could have been catastrophic.

While towing my boat down the interstate my truck lost all power from the engine and the dash began flashing with all sorts of errors. There was zero warning of this. Thankfully, I was safely able to get to the side of the interstate thankfully but I was basically dead in the water. The truck would sort of drive on its own, no input from me at all, it would just start moving if I let off the brakes and get up to about 35mph. The dash had the check engine light on, ABS light, and the transmission light on. The following messages came up on the screen; service engine, service advancetrac, hill start assist disabled, and the pre-collision assist was disabled. Thankfully no one was injured but it was incredibly dangerous that the vehicle lost all power in 70+ mph traffic, especially while towing a boat.

Engine completely fails while driving at highway speeds. Press on accelerator and no power. However Electronics, dash etc, are still on. It has happened 6 times in 2 weeks. Maverick has 26K miles. Each time I have had to coast to a safe shoulder or exit without any ability to accelerate. No warning lights, messages or other symptoms prior to occurrence. I have had it happen in "Normal" mode while using cruise control and lane assist. I have had it happen in "Normal" mode without using lane assist or cruise control. When it does happen, warning light says pull to safety, and check engine light remains on. I Am able to brake, place car in park, turn off car, restart, check engine light remains on and then am able to drive briefly again. It then happens again. Originally happened on Feb 14, 2024, then again on Feb 22, 2024, and then 4 times on February 25, 2024. Have taken back to dealer each time. Dealer cannot find anything associated with Code readings. Dealer is unable to duplicate. Ford has been unresponsive in providing any service bulletin. I am not the only Maverick Hybrid vehicle experiencing this. An outstanding engine failure and engine fire recall remains without resolution from Ford. I have given them permission to drive vehicle 100 miles, as that is when it first occurs. My vehicle is not safe to drive. My daughter and I were almost killed on high speed highway when the engine failed and 18 wheeler barreling down behind us. Ford has offered no solution or steps to compensate for this danger.

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.
