GM Wheel Lock-Up From Transmission Control Valve Defect

Posted on by

General Motors (GM) has announced a safety defect affecting the transmission control valve in certain Chevrolet, GMC, and Cadillac vehicles equipped with diesel engines. The issue involves excess wear on the transmission control valve, which could lead to a gradual loss of pressure. This defect has the potential to cause harsh shifting, and in rare cases, a momentary lock-up of the rear wheels.

The Affected Vehicle Models Are:

2021 Cadillac Escalade
2021 Cadillac Escalade ESV
2020-2022 Chevrolet Silverado 1500
2020-2022 Chevrolet Silverado 2500
2020-2022 Chevrolet Silverado 3500
2021 Chevrolet Suburban
2021 Chevrolet Tahoe
2020-2022 GMC Sierra 1500
2020-2022 GMC Sierra 2500
2020-2022 GMC Sierra 3500
2021 GMC Yukon
2021 GMC Yukon XL

GM first became aware of this issue in June 2024 through the company’s Speak Up for Safety (SUFS) program, after a customer claimed that the rear wheels of a 2021 GMC Sierra 2500 HD pickup allegedly locked up while towing a trailer. The incident caused property damage to both the vehicle and the trailer. This report prompted GM to open a new investigation.

Previously, GM had already investigated the condition, finding that excessive wear in the transmission control valve could cause harsh downshifting and, in some cases, a momentary lock-up of the rear wheels. Earlier tests and analyses suggested that the lock-up was unlikely to lead to loss of vehicle control, and no accidents or injuries were reported at the time.

In July, the National Highway Traffic Safety Administration (NHTSA) notified GM that its Vehicle Owner Questionnaire (VOQ) monitoring process had flagged additional reports that could be related to this issue. GM’s investigators conducted an extensive analysis of these reports and reviewed comprehensive field data, identifying 1,888 field reports alleging a potential lock-up condition. Further examination revealed eleven specific incidents where the vehicles veered off the road, causing minor property damage. There were also three minor injuries reported, although none were linked to a collision.

Based on these findings, GM’s Safety Field Action Decision Authority (SFADA) decided in October to initiate a safety recall.

To address the defect, GM dealers will install updated transmission control module software. This software will monitor valve performance and detect signs of excess wear approximately 10,000 miles before a wheel lock-up condition could occur. If excess wear is detected, the software will limit the transmission to fifth gear, effectively preventing a wheel lock-up scenario, which typically happens during a downshift from eighth gear. Additionally, the vehicle’s instrument panel will display a service engine light and a reduced propulsion warning message to alert the driver. GM’s number for this recall is N242454440 and the NHTSA campaign number is 24V-797.

2024 Ford Mustang Low Voltage Problem

Posted on by

The 2024 Ford Mustang has recently come under scrutiny due to a low voltage problem affecting the Remote Cluster Box (RCB). This issue can result in significant communication disruptions and software initialization problems that prevent the Instrument Panel Cluster (IPC) from functioning as intended. Here’s a breakdown of the problem and the potential risks.

The low voltage events impacting the 2024 Mustang can lead to the IPC failing to illuminate during vehicle startup or a drive cycle. When this occurs, the IPC goes completely dark, leaving the driver without crucial information, such as telltales and gauges. These elements are essential for the safe operation of the vehicle and are regulated under Federal Motor Vehicle Safety Standards (FMVSS), including:

  • FMVSS 101: Controls and displays
  • FMVSS 102: Transmission shift lever sequence, starter interlock, and transmission braking effect
  • FMVSS 108, 126, 135, 138, and 208: Additional standards related to lighting, electronic stability control, braking, tire pressure, and occupant protection

The malfunctioning IPC means safety-related telltales and gauges, like those for speed, fuel level, or warning indicators, become unreadable. This significantly raises the risk of a crash, as the driver cannot access critical safety information.

Problem Chronology

The timeline of events provides insight into how Ford discovered and began addressing the issue:

  1. August 20, 2024: The Flat Rock Assembly Plant’s Plant Vehicle Team (PVT) identified the IPC illumination problem during an analysis of warranty claims. The issue was escalated to Ford’s Critical Concern Review Group (CCRG) for a thorough review.
  2. August to October 2024: The CCRG conducted an extensive warranty claims analysis, examining whether similar problems affected other Ford vehicle lines using the same type of IPC. Fortunately, no other models showed the same failure.
  3. June 11 to October 7, 2024: Ford identified 58 warranty claims related to this issue in Mustang vehicles. Notably, there were no Vehicle Owner Questionnaires (VOQs) reported for this condition.
  4. October 18, 2024: The concern was presented to Ford’s Field Review Committee, which approved a field action to address the defect.

Although Ford is not aware of any accidents or injuries linked to the low voltage problem, the malfunction poses a significant safety risk. A non-illuminated IPC can make it impossible for drivers to monitor vital vehicle functions, potentially leading to hazardous situations on the road. The inability to see essential gauges or receive visual warnings compromises the driver’s ability to respond appropriately to changing vehicle conditions.

Ford dealers will update the IPC software to ensure the cluster functions correctly, eliminating the risk of low voltage events causing display failures.

  • Owner Notifications: Ford plans to mail notification letters to affected Mustang owners starting November 11, 2024.
  • Recall Information: The recall is identified by Ford as 24C35 and registered with the National Highway Traffic Safety Administration (NHTSA) under campaign number 24V-802.

If you own a 2024 Ford Mustang, it is crucial to stay informed about this recall and ensure your vehicle receives the necessary software update. This simple fix will help keep your Mustang safe and compliant with federal safety regulations.
