Ford Maverick Hybrid key fob problems

Filed Jun 23, 2025 · Electrical · MA

While traveling at speed there was a severe malfunction of the vehicle's stereo system. While driving the stereo was initially silent but later began to produce extremely loud noise/static. The volume of the noise was so extreme I had to take my hands off the steering wheel to cover my ears. The stereo did not respond to any power or volume input to stop the sound and I was forced to quickly pull over to the side of the road to turn off and exit the vehicle. The sound only stopped after exiting the vehicle and locking with the key fob. There were no warning signals prior to this failure. I have experienced this problem several times in the past while the vehicle was parked, when first starting the vehicle. This was the first instance of experiencing the problem while driving, within the first 1 minute after starting the vehicle. The stereo was initially on and set to a reasonable volume level, but was malfunctioning and completely silent. After driving for ~45 seconds the stereo began producing this extremely loud noise. I have found several reports of similar stereo issues with the Ford Maverick and also F150 trucks that are equipped with a similar B&O sound system. Â This malfunction could potentially lead to an extremely dangerous situation, inability to safely operate the vehicle, and loss of situational awareness. I have dash cam footage of the incident, which I can provide upon request.

My 2024 Ford Maverick manufactured 9/24 has failed to unlock on two separate occasions with key fob and the interior lights failed to come on when I unlocked the driver door with the mechanical metal key. When I checked the charge status of my battery it was depleted below 75%. I also noticed that the battery was a flooded acid type and is installed under the rear seat within the passenger compartment. The placement of a flooded acid type of battery in the passenger compartment poses a significant danger and risk of acid exposure in the event of a collision.

Issue Description: The battery has been consistently failing. The battery has been replaced twice in 2024 already. On both occasions after replacing the battery, the new battery was drained and dead again within 48 hours. The battery totally loses power and has to be jumped off nearly daily, sometimes two and three times per day. The battery drains so low that the doors won't unlock with the key fob, no interior lighting or engine power. Safety - Vehicle constantly won't restart in rural locations with no vehicles around to jumpstart the vehicle. The Ford Service Center has inspected the vehicle on several occasions and placed the vehicle on it's diagnostic tool twice this year, but it never reveals anything that is draining the battery. There are no warning signs. These 2022 Ford Maverick Hybrids simply do not start, and FORD has no solution to these daily repetitive battery drains. Any time the engine is turned off, there is a very high probability that the truck will not restart without locating someone to hook up jumper cables and jumpstart the vehicle. There are hundreds and hundreds of online complaints about this very issue with the draining batteries on the 2022 Ford Maverick Hybrids. Yet, Ford refuses to issue a recall on the vehicles or make any efforts to resolve the outstanding issue for customers who have purchased these defective 2022 Ford Maverick Hybrid Trucks. The customers are simply stuck with defective vehicles that won't start.

Twice, within a one week period, my hybrid vehicle failed to start. In fact, the key fob failed to unlock vehicle. I changed the battery in one key fob and still wouldn't unlock the vehicle. I had to unlock vehicle manually with the key and vehicle still wouldn't start. Vehicle dash board and all interior lights not working. Both times service was called and vehicle started right up with a jump from a battery pack. No check engine light was displayed either time. I have checked the Ford Maverick owners website and a bad wiring harness appears to be a problem that many hybrid owners have reported that Ford replaced to resolve this problem. I am concerned that this defective wiring harness could be a fire hazard. Also now the vehicle is unreliable and could leave me stranded on the highway or die in heavy traffic or when trying to merge or exit the interstate near my home.

Only had my Ford Maverick for 3 weeks and went to start the truck and it was completely dead. Couldn't even use the key fob. It went into Deep Sleep Mode. Had to have it towed to the dealer. Still waiting on it.

Returning home from vacation. Stopped for lunch. Went back to vehicle and Vehicle was dead. After repeatedly hitting unlock button was able to unlock vehicle. Since I was aware of this potential issue I had a battery booster jump pack in the vehicle...but if you can't unlock the vehicle you are out of luck. Luckily after repeatedly hitting unlock...it eventually unlocked. When I got in I tried to start it but instead got a message saying "No Key Detected". I got my battery pack out and hooked it up...hit boost. Went to start the Mav and instantly it started. When I got ready to go, I could not move the dial from Park to Drive and still was getting the "No Key Detected" message. It took about 2 or 3 minutes for the key to be detected. Drove vehicle to dealership and and am awaiting repairs. Suspect this is a wiring harness issue that have been reported by numerous Maverick owners. Seems like a TSP/Recall is in order! Only have 1,155 miles on this new vehicle.
