2023 Ford Maverick electrical system problems

“My 2023 Ford Maverick Hybrid experienced repeated 12V battery discharge and “Deep Sleep” events associated with Recall 24C01 and SSM 53801. The vehicle repeatedly discharged the 12V battery while parked under normal conditions. In January 2026, after approximately two weeks parked in freezing temperatures, the battery experienced a complete discharge and the vehicle required multiple jump-starts to remain operational. Ford dealer records later confirmed that the corrective action associated with SSM 53801 had not been applied prior to the failure event despite prior complaints and service visits. The repeated discharge events resulted in failure of both: the original factory battery, and a replacement AGM battery installed at owner expense. This condition created repeated stranded events and loss of vehicle reliability. I am submitting this complaint because the issue appears directly related to documented parasitic drain conditions already acknowledged by Ford in Recall 24C01 and SSM 53801, and because the failure condition persisted before corrective action was finally applied.”

“The contact owns a 2023 Ford Maverick. The contact stated that while driving at an undisclosed speed, the brake lights and turn signals failed to function as intended. In addition, the message “Brake Light Failure” was displayed. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The dealer was made aware of the failure, and the contact was informed that the parts were not available to repair the vehicle. The contact received notification of NHTSA Campaign Number: 26V104000 (Electrical System, Exterior Lighting); however, parts were unavailable for the recall repair. The contact's husband purchased and replaced the light bulbs lights. The manufacturer was made aware of the failure, and a case was filed. The contact was informed that there was no assistance available. The failure mileage was approximately 50,000.”

“Hybrid Ford Maverick electrical system began to go into a save battery mode -no interior lights, only driver side door operated, and other system failures. Dealer replaced battery under warranty and general recall for this issue. A few months later same characteristics started showing up -interior lights not working, only driver's side door operational, etc. This time the warranty had expired and the dealer, along with Ford Motor, told me any repairs would be at my expense, 100%. I feel problem was never resolved, even with replacement battery. Ford and dealer should address this problem. I'm sure I'm not the only one with this battery and electrical issue. After all, there was a full recall for the battery failure. Having no interior lights, unable to enter except driver's side, and other manifestations are inherently unsafe.”

“"2023 Ford Maverick Hybrid (VIN: [XXX] ). The vehicle has a chronic 12V parasitic drain defect. Authorized dealer Champaign Ford City provided false information, stating software was current when it was not. This led to a 100% discharge in freezing temperatures, requiring multiple jump-starts to reach the dealer. This discharge destroyed a high-quality owner-purchased AGM battery. Despite Safety Recall 25S02 mandating no-cost battery replacements for these vehicles, the dealer charged me for a Ford battery. Safety concern: Vehicle unreliability in sub-zero temperatures and dealer failure to adhere to federal recall reimbursement guidelines."”

“Battery is constantly in battery saving mode. It use to do it only when I was on vacation for a week or so. Now it has been doing this every single day for about the last two month.”

“I had a problem once with the interface module, and since it was still under warranty, the Ford dealership in Fairfield, California replaced it and at 3:32 AM today January 3, 2026. The interface module turned off for a couple seconds and then turned back on which was basically the same problem as it was when I complained and had them replace it.”
