NHTSA investigations into the transmission and drivetrain on the Explorer

Rear axle bolt failure. Closed feb 15, 2024, led to recall 23V-675.

NHTSA summary
On July 17, 2023, the Office of Defect Investigation (ODI) opened this Recall Query (RQ) after receiving 2 consumer complaints alleging loss of vehicle forward power and/or loss of transmission torque of the rear wheels in model year (MY) 2020-2022 Ford Explorer vehicles (subject vehicles). The RQ was opened to focus on the effectiveness of the remedies of Recalls 22V-255 and 23V-199 related to the alleged problem. Recall 22V-255 involved replacing the bushing and axle cover in the following subject vehicles: 3.3L FHEV Police built before October 14, 2020, and 3.3L Gas Police vehicle built before January 31, 2021. For 2.3L RWD, 3.0L PHEV, 3.3LFHEV, and 3.0LST retail (non-police) vehicles, the recall provided an PCM software update to engage the Electronic Park Brake (EPB) when Park is commanded. The recall addressed a breakage of the rear axle bolt that can cause the driveshaft/half shafts to disconnect, resulting in a loss of transmission torque to the rear wheels necessary to hold park. If the parking brake is not applied, the loss of the primary park torque will allow the vehicle to roll in park increasing the risk of crash and injury. Recall 23V-199 addressed 674 of the subject vehicles produced from February 2, 2019 to April 4, 2022, which received an incorrect remedy under Recall 22V-255. The affected vehicles had received a previous Powertrain Control Module (PCM) update which did not include an automatic EPB engagement when vehicle is shifted to park. On October 17, 2

Vehicle rollaway allegations. Closed feb 12, 2013.

NHTSA summary
This investigation is being closed based on several considerations.By the most inclusive counting of all alleged rollaway incidents (i.e., counting all alleged rollaway incidents and assuming a singular failure mechanism), the incident rate is low, however during EA09-013, ODI identified a number of different failure mechanisms in 180 incidents related to the alleged defect.The highest rate for any particular failure mechanism, the failure of the Automatic Transmission Parking System, was 4.4/100K.The next-highest failure rate was for the BSI System, at 3.4/100K.For all identified failure mechanisms there has been a drastically declining trend including very few incidents occurring in recent years.Accordingly, this investigation is closed.The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist.For additional information regarding this investigation, see the complete closing resume in the document file for EA09-013. The ODI reports cited above can be reviewed at www-odi.nhtsa.dot.gov/owners/SearchNHTSAID under the following identification (ODI) numbers:10168454, 10279630, 10280078.

What owners wrote

“Transmission torque converter attempts to lockup when vehicle is in gear, at idle and brakes applied. This causes the engine rpm to drop or stall. This causes an unexpected delay and hesitation when accelerating from a stop followed by an unexpected acceleration surge. This issue has been confirmed by an independent service center. No computer codes or warning signals on the dash are present.”

“The car was up on ramps, to replace a sensor, in park and slipped out of gear rolling backwards with force. Someone could have been under or behind the vehicle. Other vehicles could have been behind, property could have been damaged. The cars door caught the building and pulled it all the way back against the front fender.”

Should you keep driving it?

This page can't tell you that. 2 of 50 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.

File your own report with NHTSA. Complaint counts are how a problem gets an investigation.
