2024 Ford E-450

On two separate occasions, the vehicle's left rear wheel studs have broken off clean with the hub and both rear dual wheels departed the vehicle while in motion. This issue was reported to the local FORD dealer and they reported that they do not know why this is happening. This has happened to five (5) of our other vehicles as well. I am a fleet manager for an EMS service and we have a total of ten (10) of these Ford chassis. The wheels coming off present a hazard to oncoming traffic not to mention the safety of our team members and patients being transported on our ambulances. We sent the vehicle to Kilgore Ford in Kilgore, Texas and they advised they are not sure how this keeps happening. There were no warning lamps that gave the driver a warning that something was wrong until the truck started vibrating and the wheels came off. All of our vehicles, including these FORD Chassis', undergo Preventative Maintenance every 5,000 miles and we check torque on these FORD chassis' because of these continued failures. Our torque wrenches are checked annually for calibration and we utilize the FORD Diagnostic Software and FORD Torque Specification which are followed on every preventative service.

The brand new JAYCO GREWHAWK is making a whining sound from the chassis. I have not even driven it more than 50 miles. this vehicle needs to be recalled for whatever chassis issues or it could be transmission issues. I will take it back to FORD but this is really bad on ford to sell brand new RVs with such whining sound coming from the chassis. Please alert the new owners about the issues . thank you, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Some 2023-2026 F-53 Motorhome Chassis/F-59 Commercial Stripped Chassis and 2024-2026 F-650/F-750/E-Series vehicles equipped with a 6R140 transmission may be limited to 5th gear and reverse gear only. Additionally, the driver will be able to shift back to park. Diagnostic trouble codes (DTC) P2701, P2704, P0757, and/or P0733 may be stored in the powertrain control module (PCM). This may be due to PCM software being unable to command the transmission solenoid clutch actuators when the battery has a low state of charge (SOC) and/or the vehicle has been jump started. To restore proper transmission functionality, charge the battery as stated in the Workshop Manual (WSM), Section 414-01 Charging System > General Information. Cycle the ignition on then off and leave the vehicle off for 5 minutes to confirm the condition is no longer present. To prevent this issue from reoccurring, refer to the Owner's Manual > Storing Your Vehicle > Preparing Your Vehicle for Storage > 12V Battery.
