2022 Ford Maverick Hybrid

•My saga continues driving my Maverick hybrid to NY to visit my mom for Mother’s Day hoping the new Battery/Smart Junction Box that my Ford Dealer replaced on 4/9 was the culprit in the 2 shutdowns experienced on [XXX]. •[XXX] Maverick shutdown 3x driving on highway around 70 mph during 400-mile trip. Had to wait approx. 20-minutes each time for engine to cool off and reset from electric mode to continue on. NY Ford dealer diagnosed on 5/13 and reports: U1010 is present , Hybrid Powertrain Control Module is suspected to be bad They said it would take a few days to get a new PCM from Ohio warehouse. I couldn’t wait and had to return to MD for work on 5/14. •[XXX] Shutdown 4x driving on highway around 70 mph during 400-mile return trip. Had to wait approx. 20-minutes each time for engine to cool off and reset from electric mode to continue on. Fortunately, no accidents and I was always able to find a safe spot on the side of the road to pull over to and wait for 20 minutes or so. •[XXX] Received Ford Safety recall notice 23S27 for Software to repair 2022-2023 Mavericks to update the Powertrain Control Module (PCM) free of charge (parts and labor). Note NY Ford Dealer recommended replacing PCM vs. repairing or updating it. Is there a definitive way to test which is best, replace or repair? •[XXX] Just found this at Check for Recalls: Vehicle, Car Seat, Tire, Equipment | NHTSA dated May 3, 2024 Manufacturer Recall Number 24S33 Both I and the NY Ford Dealer were unaware of this recall, 24S33 or they could had tried updating my PCM. Thanks Ford! INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While driving on the highway my car randomly went into limp mode rapidly and nearly caused an accident. I do know the code was U1011. It is a PCM fault stating the PCM and the engine has lost connection. It has been noted to turn on and off randomly and cannot be replicated until it reappears. Dealerships have been giving the run around that it goes away so it’s not a problem. Everyone to include me is having the problem after getting a recent PCM update recall done. My local ford deal shops even say they can see the fault happens, but will not do anything to solve the issue. This fault puts me and everyone in the road as risk randomly sending my car into limp mode without warning or signs.

Drove my car home and parked in my driveway with no issues. 9 hours later when I was about leaving for work, started the car but car won't start. I jumpstarted the car then all of a sudden the (Drive) Shift knob light was flashing, warnings started flashing, hill start assist not available, service vehicle soon, pre collision assist not available, service advance Trac, and parking brake applied automatically and total loss of power. When I pressed on the gas, it wouldn’t go and no throttle response. When I let off the brake and was NOT pressing the gas, it would start to accelerate all on its own up to about 28/29 mph all on its own, acting like it was in cruise control

The contact owns a 2022 Ford Maverick. The contact stated that while driving at an undisclosed speed, the vehicle accelerated unintendedly. Additionally, the contact stated that while driving at an undisclosed speed, the accelerator pedal was depressed, but the vehicle failed to accelerate as intended. Several unknown warning lights were illuminated. The vehicle was taken to the dealer however, the failure could not be duplicated. The vehicle was not repaired. The manufacturer was made aware of the failure and a case was opened. The failure mileage was approximately 36,000.

Check engine light Power train light (wrench)/reduced power Brake light pre-collision light/pre-collision unavailable Hill assist message The above warning lights appeared out of no wear when pulling up to a stop light.. The parking break was automatically engaged and the above warning lights appeared. When I tried to accelerate to make a turn, the truck would not accelerate with me using the accelerator, but it started accelerating on its own. I had to keep riding the brake because it keep accelerating on its own until I was able to get it to a parking lot.

On 4/27/24 Vehicle went into limp mode after driving for less than 90 seconds. Multiple various errors messages (powertrain, hill assist, collision, check engine) lit up, vehicle was accelerating on its own when in drive. No error messages prior to this incident. Similar incident happened around 3/10/23 while at Ford service for recall software updates but issue was not confirmed at that time. Vehicle is at Ford service now for second incident. Ford service states when the vehicle got a recall completed for the SOBDCM update, it triggered the vehicle to not update fully and causes the warning messages and can force the vehicle to go into limp mode and lose power.

While driving 70mph, Maverick truck lost power and was forced to pull onto shoulder. Restarted car after several systems were flashing as disabled. I was only able to drive 34mph top speed. After stopping for gas and shutting vehicle off for 30 minutes, car restarted without warnings (only check engine light on) and were able to drive 70mph again. I'm assuming this is the 24S24 recall. My dealership read the codes but were not aware of the recall or its remedy so I'm still waiting for recalibtation.

The component in question is the powertrain control module for my Maverick. After having the relevant powertrain recall reprogramming done (23E09), I was driving down the highway when I received a rapid series of warnings from my car including "Pre-Collision Assist Not Available", "Service Engine Soon", and "Service AdvanceTrac" [sic]. I lost all engine power at that point, and was steadily decelerating with no response from the accelerator. There was no advance warning or messages. There was an imminent threat to my safety at that time. The loss of all power rendered the car unsafe to continue driving on the highway, and prevented me from leaving the highway in a safe manner. I was able to pull off the highway at a fortunately nearby exit ramp, however, I was unable to accelerate and was only able to coast to the nearest safe parking space. I subsequently turned my car off and on again, I found that when in drive the car would accelerate by itself to no more than 35 miles per hour, and was unresponsive to the accelerator pedal-it would only slow down if the brake was applied. Upon arriving at my original departure point, I then turned my car off and attempted a BMS reset unsuccessfully. The next day (<12 Hours since the initial failure), my car was functioning properly again but was soon seen by a dealership for service. I was informed by the service representative that this is a repeated issue brought to their attention for this make & model, with a consistent trend of these issues occurring after the powertrain control module was reprogrammed as part of an update. The powertrain module was again reprogrammed/flashed, and the issue has not repeated since the initial failure, though it is available for inspection.

3/28/24 My 2022 Ford Maverick Hybrid’s engine shut down and lost acceleration driving 70-80 miles an hour on a highway going through hills after 100 miles. Vehicle displayed a bunch of dashboard alerts as it soon lost all acceleration and would only drive slowly in Electric mode. I pulled over and tried again, but it was stuck in electric mode with barely any acceleration and displayed Check engine, service vehicle, bring to the dealer, etc., and a few other alerts. I shut off the engine and tried it again 5 min later, and it was still in electric mode. I shut it off again and waited around 15 minutes while trying to get roadside service using my Ford App, which showed local dealers but I could not find any towing service. Then, after the truck cooled down, ~15 minutes, it started up fine, and I could drive it. The engine shut down again after about another hour, displaying the same dashboard alerts as seen earlier. I pulled way over, shut everything down, and waited 10-15 min or so , and it started and ran fine to get me home in 30 min or so. I brought it to the Ford dealer the next day, 3/29/24, it took them 8 business days, and they said it was fixed on 4/9/24; they replaced the Battery/ Smart junction box.
