2023 Ford Maverick Hybrid

As I was driving along the highway the vehicle suddenly lost all propulsion. The electric shifter indicated the vehicle was no longer in drive and several errors/warnings appeared on the dash including “Pre-collision assist not available, Powertrain Malfunction/reduced power, and service engine soon”. No error messages were visible prior to this occurring. The vehicle can be made available upon request. It is currently at the dealer for the second time for this issue in the last 3 days. Both times the vehicle was rendered unusable in high speed/highway traffIc, putting both myself and fellow motorists at risk by forcing me to coast through a line of cars to reach the shoulder. Also, being on the side of the highway as cars fail to move over for the disabled vehicle poses its own risk to my safety as well as other motorists. The second incident occurred at approximately 7pm march 7th along the same highway and in identical fashion. The problem has not been reproduced by a dealer, however, they identified and cleared the error codes stored by the vehicle. The service manager said he believed it was a result of a recent recall software update. The ford dealership that sold me the car has inspected the vehicle. My assessment is that this issue is related to a recent update performed by ford service regarding a recall/s. This vehicle was just serviced for its 30k maintenance and received the recall update/s and since then has broken down and been towed to the dealer twice.

This is my second complaint on this vehicle for the same issue. While driving on the interstate my vehicle suddenly loses all power and shuts off. After the initial incident the vehicle was sent to a ford dealership. It was stated on repair order that: found code u1010: invalid internal control module monitoring data reveived from hybrid pcm Correction ford states to check for updates clear codes and retest, if no issues comes back communication network got crowded The vehicle was released to me and the same issue occurred approximately 45 minutes into my trip hard. This is very dangerous to be happening with no resolution from Ford.

VEHICLE PROPULSION SYSTEM (ENGINE AND HYBRID SYSTEM) QUIT WITHOUT WARNING ON A BUSY FREEWAY. WOULD NOT RESTART WHILE MOVING AND ATTEMPTING TO GO TO SAFE AREA. AFTER PARKING ON SIDE OF FREEWAY AND SHUTTING OFF ALL ENGINE RELATED SYSTEMS I WAS ABLE TO RESTART AND CONTINUE. SAFETY: NOT SAFE TO PARK IN MIDDLE OF FREEWAY. NO INDICATIONS OF PROBLEM ON ANY INSTRUMENTS. FUEL WAS AT ABOUT 5/8 FULL. TAKING CAR BACKTO CARMAX TOMORROW UNDER 30 DAY RETURN POLICY.

I was driving on a freeway and my vehicle went into "Powertrain malfunction/Reduced power mode " and slowed me down from 65 -70 miles an hours to under 20 miles an hour. This almost cause a semi to slam into the back of my vehicle missing me by inches. The dealership is unable to recreate this issue but confirmed it did happen. Ford and the dealership have been giving me a run around with this since they can't diagnose the issue.

- Lithium Battery risk- "deep sleep" vehicle goes into deep sleep and is dark, no interior lights. SSM 51725 was performed - what it accomplished was removing the APP notification of deep sleep, not the problem. There are numerous similar complaints on the "Maverick forum", usually with the recommendation to "drive more", initially a poor battery connection was thought to be the problem, that has been resolved. The battery has been tested and been to be found in compliance - the issue is not the starting capacity but in the reserve capacity or the battery management system. Some are AGM some are flooded the risk is hybrid owners are carrying battery jump boxes for safety and reliability, OEM battery replacement is a struggle at the dealership, once deep sleep issues hit, battery issues change to not starting. The danger is that the owner is using a portable jump box in risky situations plus the always risk of carrying an additional lithum battery in the passenger compartment for reliability. Many owners have replaced the original battery, out of pocket, with good results

While on the interstate, the vehicle suddenly shut off, leaving the instrument panel fully lit with every warning light. The vehicle was unresponsive and powerless, posing an extremely hazardous situation for myself, passengers and others on the road. After I was able to get into a safe location I attempted to start the vehicle again. It remained unresponsive for quite some time and the vehicle had to be towed to a dealership. A quick google search indicates this issue is becoming prevalent in the Ford Maverick.

Brakes grab unpredictably when slowing to a stop. When car has slowed from higher speeds down to less than 6 mph, the brakes suddenly grab, stopping the vehicle without warning. The degree of grabbing is never the same twice, happens almost every time I stop. It is especially bad after vehicle has been parked for a period of time, and is noticeably worse in moist conditions. I feel that this condition can cause a car behind me to possibly hit me. My FORD dealer has had service tech drive it and confirm this is occurring, but they have thus far been unable to apply a fix.

On occasion, at slow speeds, typically when coming to a slow stop (such as at a stop sign or light), the vehicle's brakes appear to "grab", car "shutters", feels as if car's brakes are locking or vehicle is about to turn off. I am the original owner of this vehicle, less than 7,000 miles, this problem has happened approximately 10 times. This problem could have resulted in a dangerous situation, the last time this happened someone was crossing in front of me at a crosswalk and I was not sure vehicle was going to stop.
