AUTOMATIC REVVING INCIDENT 1 DATE: November 25, 2025 TIME: about 4:05pm LOCATION: [XXX] WEATHER: Slight rain, around 37º F VEHICLE STATUS: In Park, heat dial turned on. DESCRIPTION OF ISSUE: Turned key to on position while in park. ICE engine immediately turned on and revved all the way, as if the accelerator pedal was pressed down all the way. Pedal was NOT under floor mats. Immediately turned key to off position, let sit for a moment. Turned key to on position again and issue seemed to be resolved. No check engine lights or other codes were showing on the dash cluster. AUTOMATIC REVVING INCIDENT 2 & 3 DATE: December 2, 2025 TIME: about 4:05pm LOCATION: [XXX] WEATHER: Clear, around 27º F VEHICLE STATUS: In drive, heat dial turned on. DESCRIPTION OF ISSUE: Turned key to on position while in park. Heat was on. Immediately turned dial to “D,” and engine proceeded to again rev all the way up. However, this time, full power was transferred to wheels, causing vehicle to attempt to lunge forward. Luckily, I was on an icy patch of the road, and the tires spun instead of gaining traction. I immediately slammed the brakes and turned the car off. Waited about 2 minutes and then turned key to on position, and the exact same thing happened again. No check engine lights or other codes were showing on the dash cluster. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The 2023 Ford Maverick Hybrid is experiencing a recurring safety failure of the Front CV Axle Shafts. The vehicle exhibits violent, uncontrollable shaking of the front end during acceleration at highway speeds (40–65 MPH). This severe vibration compromises vehicle stability and steering control, creating a significant safety risk during merging or overtaking maneuvers. The vehicle was previously repaired for this exact issue by an authorized Ford dealer on May 30, 2024 (at ~32,000 miles). However, the failure has recurred 18 months and 33,000 miles later. Inspection of the current failed parts reveals that during the 2024 warranty repair, the dealership installed obsolete, superseded part numbers (Series "NZ", specifically NZ67-3B436) instead of the updated, corrected design (Series "SZ") released by Ford to fix this known defect. Because the dealership replaced defective parts with the same defective/superseded design, the safety hazard has returned prematurely. The defect was previously confirmed by a dealer technician. The current failure is confirmed by visual inspection of the part labels showing the obsolete "NZ" code. No warning lights appeared prior to failure; the symptom is immediate mechanical vibration under load.

I had been driving for 2 hours on the interstate when the truck starts losing power and warning lights start flashing. I got the truck to the shoulder before it slammed to a stop. I turned the engine off and waited until all the power turned off before restarting. The truck would only run in limp mode at 35 mph. I drove on the shoulder of the interstate to the next exit. I disconnected the battery and reconnected which allowed me to drive it normally to the dealership. After two days the dealer called to say they didn’t see any codes and there wasn’t anything wrong with it even after I sent pictures of the warning messages. This is the 5th time this has happened under similar circumstances.

This exact situation has occurred twice in the past 6000 miles driven. Both occurred while driving at highway speeds, once on I85N and once on I75N in GA. Our 2023 Ford Maverick XLT Hybrid suddenly and unexpectedly loss power and shutdown. This forced us to make an emergency stop and attempt to pull over in high speed, heavy traffic in both instances. The vehicle eventually restarted and was drivable with a check engine light illuminated. The DTCs were read with an OBDII scanner and were recorded as P0811, P0E71 and P1920. The first time this occur the vehicle was taken back to Ford under warranty and they said they reprogrammed the PCM and another control module and assured us it was repaired. Obviously that is not the case. The vehicle is currently with Ford being diagnosed. Please follow up on this one. We're not the only Maverick Hybrid owners to have this unfortunate and very unsafe experience. This situation of a vehicle suddenly dying in heavy traffic is going to get someone killed. Thanks in advance for your consideration in this matter. We would like a better explanation from Ford besides "We reprogrammed a computer".

At 20k miles the vehicle starts shaking back and forth and rattling while accelerating and I brought it to the dealership and its being serviced under warranty to get both front CV axels replaced. It was shaking so badly and vibrating the whole vehicle, the dealership told me it was unsafe to drive when they saw how badly the axels failed. There were no warnings or check engine lights. Especially dangerous because it doesn't shake at low speeds only when accelerating and at high speeds.
