2025 Ford F-150 Hybrid

Vehicle demonstrates an intermittent lag during acceleration, particularly during throttle position changes. Typical throttle response is appx 0.5s as measured by stopwatch. When the issue is replicated the delay can exceed 1 second. This is most concerning during situations where moderate to brisk acceleration is needed at a specific time such as turning across traffic at an intersection or merging with traffic flow with a large speed disparity from one lane to the other. Vehicle has been taken to multiple Ford dealerships multiple times. The ECU and TCU have been reprogrammed and the situation does not change. Dealership has noted an issue one time but otherwise claims that they have not been able to show the issue to be out of allowable parameters by Ford. Numerous forum posts online discuss the same symptoms and comment similar findings by Ford dealership techs. What they can readily replicate is understood but considered "normal". This behavior has created 2 different situations that nearly culminated in severe accidents with myself driving the vehicle, one time with my child in the seat exposed to oncoming traffic when the accelerator lag caused a severe situation. The first severe situation was crossing traffic outside of my child's school with oncoming traffic having to slam on brakes in order to avoid the collision. The second situation happened while merging lanes on a highway going from ~45mph up to ~60mph and almost caused the neighboring lane to rear end the vehicle. The dealerships have noted the delay exists but to be considered "within allowable limits" when it happens. No warning lamps come on as a regular pattern. This pattern first appeared when the vehicle was less than 500 miles on the odometer. The first dealership ignored the information.

New 2025 F150 Lariat with 3.5L V-6 Twin-Turbo Full Hybrid. Truck was sitting in garage and off when suddenly a message appeared on the digital speedometer area saying there was a powertrain fault. Truck only had 280 miles. At about 310 miles, service light came on indicating service was due. Checked FordPass app and the on board diagnostic program indicated there was a power train fault detected. I’ve checked several online forums and many owners are reporting that there are known Ford Technical Service Bulletins (TSB) regarding this issue and the issue has to due with faulty starter, alternator, and battery. Ford know about this issue and that it is common yet they have failed to issue a recall to fix all of these.

The first indication of a problem was a red "SERVICE CHARGING SYSTEM NOW" message at 121 total vehicle miles and continued to be intermittent. The vehicle was returned to the selling Ford dealership the next day. After a day in the service department, they were unable to duplicate the problem. This same message reappeared sporadically, but did not seem to affect the safe operation of the vehicle. At approximately 1460 miles the red "SERVICE CHARGING SYSTEM NOW" and many other messages appeared while I was on an interstate traveling at 70mph. As I started maneuvering for the nearest exit, the steering would not respond without using EXCESSIVE force, creating a dangerous, unsafe situation. I managed to safely exit the highway and park the vehicle. It would not reset or operate normally. The vehicle was subsequently towed to a Ford dealer. After 3 weeks of troubleshooting, they replaced the main AGM 12V battery (Part Number BAGM 94RH7 800) and the DCDC Converter (Part Number ML3Z 14G649 F). These components may be available from Astro Ford in Biloxi, MS for inspection.
