2024 Ford Ranger electrical system problems

“While driving a 2024 Ford Ranger Raptor at approximately 40 mph under normal road conditions, the vehicle experienced a sudden and uncommanded drive-mode failure. Without any driver interaction with the center console GOAT mode dial, the truck spontaneously began cycling through drive modes and attempted to engage the 4-wheel drive system. The driver's instrument cluster displayed a warning message stating "Stop to go to 4L," indicating that the vehicle's computer module was actively trying to shift the transfer case into 4-Wheel Drive Low while traveling at highway speeds. While the vehicle's digital electronic guardrails successfully blocked the physical shift into 4-Low due to the vehicle's current velocity, the uncommanded shift command represents a severe safety hazard. If the software safety parameters fail to block an unprompted 4-Low shift at these speeds, it could cause catastrophic mechanical failure, instantaneous drivetrain lockup, or an immediate loss of vehicle control. This is a known issue within the owner community that requires an official investigation to determine if a manufacturing defect exists in the All-Terrain Control Module (ATCM) or…”

“The contact owns a 2024 Ford Ranger. The contact stated that while driving at approximately 15 MPH and making a U-turn, the vehicle experienced a total loss of motive power. The Service Emergency Brake and Trailer Brake Assist warning lights illuminated. The vehicle was towed to a local dealer, where it was diagnosed; however, the diagnosis details were unavailable. Additionally, during rainy weather, water intruded into the cabin and accumulated, leaving the seats wet and causing mold growth. The local dealer was contacted on several occasions regarding the water intrusion. Upon further investigation, the contact associated the failure with NHTSA Campaign Number: 26V238000 (Structure, Electrical System) and NHTSA Campaign Number: 25V541000 (Air Bags), suspecting that improper completion of a prior recall repair contributed to the failure. The manufacturer was notified of the failure by telephone and email. The failure mileage was approximately 50,148.”

“The vehicle intermittently changes its drive mode on its own, with no input from the driver. This has happened approximately 6 to 12 times. It occurs in two situations. While stopped at a traffic light, the vehicle has switched itself into Rock Crawl mode, and on other occasions into Baja mode. During at least one Rock Crawl event I believe the rear differential locker engaged, though I did not photograph the cluster to confirm it. The vehicle has also attempted to change drive modes while driving on the highway at speed. When it happens, the drive mode change animation appears in the instrument cluster. If I notice it immediately I can manually reselect Normal mode before the new mode fully engages. If I do not catch it in time, the mode engages. Safety risk: an unrequested change into Rock Crawl or Baja alters throttle mapping, transmission shift scheduling, traction and stability control calibration, and driveline configuration, and in Rock Crawl potentially the differential lockers. A mode engaging while stopped and then pulling into traffic, or the system attempting a mode change at highway speed, produces a loss of expected vehicle handling and response.…”

“In the 21 months I have owned this 2024 Ford Ranger Lariat, it has changed driving modes 15-20 times ON ITS OWN. It goes from NORMAL OR ECO all the way to SAND, from 2wd to 4wd lo if I am stopped or 4wd high, (while telling it cannot go to 4lo if I don't stop), when I at at highway speeds.It also locks the differential so steering is somewhat compromised. If this thing decides to overrule the speed requirements for shifting to 4lo on the freeway, this would put others at risk. The truck has changed modes while Idling, at a cold start, and at driving speeds. the dealer says they could not replicate the problem, (it is very random), and that they found no trouble codes. I believe that engineers would only assign trouble codes to something they think is possible. This has happened since the first night I took it home, but until last month when it did it while I was alone in the truck, I thought my wife was accidentally hitting the switch on the center console. Searching this on the internet will find many people reporting the same problem, with a very small number reporting that their dealer replaced the selector switch, (ATCM). No warning lamps appear other than…”

“The drive mode suddenly changes without input from the driver. Sometimes the vehicle will change from 2H to 4H without touching the mode selector knob. this is dangerous for the vehicle to randomly change drive settings without the driver knowing. There is an electrical issue or short in the mode selector dial.”

“Filed a complaint that Rangers had a recall on wiring harness and this vehicle was made in the Michigan plant where other Rangers had the recall. This particular Ranger should have been included in the recall. The dealership refused to do their due diligence. I filled a complaint and have a case number. CXH09344864X2D6B2. These issue needs to be resolved in a timely manner as it can cause fires and children are riding in this vehicle.”
