Transmission Control Valve May Lock Rear Wheels in 2022 GM SUVs

Posted on by

NHTSA Campaign Number: 26V-085

Owners of certain 2022 Cadillac, Chevrolet, and GMC full-size SUVs should be aware of an important new safety recall involving a potentially dangerous transmission defect. According to the National Highway Traffic Safety Administration (NHTSA), a problem with the transmission control valve in affected vehicles may cause the rear wheels to lock while driving, significantly increasing the risk of a crash.

This recall affects several of General Motors’ most popular SUV models equipped with a 10-speed automatic transmission and Electronic Transmission Range Select (ETRS) system.

Vehicles Affected by Recall 26V-085

The recall applies to the following 2022 model year vehicles:

  • Chevrolet Tahoe
  • Chevrolet Suburban
  • GMC Yukon
  • GMC Yukon XL
  • Cadillac Escalade
  • Cadillac Escalade ESV

Only vehicles equipped with the 10-speed transmission with ETRS and built within a specific production window are included.

What Is the Transmission Control Valve Problem?

General Motors determined that a defect related to motor vehicle safety may exist in certain vehicles due to excessive wear inside the transmission control valve body.

Over time, internal components of the valve may wear prematurely, which can lead to:

  • Loss of hydraulic pressure inside the transmission
  • Unexpected valve movement
  • Harsh or abnormal shifting behavior

In rare situations, this condition may cause the rear wheels to momentarily lock — or remain locked until the vehicle stops.

Why This Defect Is Dangerous

Rear wheel lockup while driving can cause a driver to lose control of the vehicle, particularly at highway speeds or during turns.

According to the NHTSA:

If the rear wheels lock up while driving, there is an increased risk of a crash.

GM is aware of at least one reported crash potentially linked to this issue, though no injuries have been reported.

Warning Signs Drivers May Notice

Drivers may experience warning symptoms before a serious failure occurs. These include:

  • Harsh or rough shifting
  • Sudden or aggressive downshifts
  • Unusual transmission behavior

However, because the defect involves internal wear, symptoms may develop gradually and may not always provide sufficient warning before a lockup event.

What Caused the Problem?

GM’s investigation found that transmissions manufactured between April 2022 and September 2022 contained unique internal hardware that may accelerate wear inside the transmission control valve.  Additionally, affected vehicles were not equipped with diagnostic software capable of detecting early valve wear.

Excessive wear can create a fluid leak inside the valve body, causing a pressure drop that allows internal transmission valves to move unexpectedly — leading to wheel lockup in extreme cases.

How the Recall Was Discovered

The issue came to light after a customer reported a transmission lockup through GM’s internal Speak Up for Safety (SUFS) reporting system on November 5, 2025. The incident allegedly caused a loss of vehicle control and a collision with a guardrail.  GM opened a formal investigation later that month and reviewed field data spanning nearly two years.  Investigators identified 13 field reports potentially related to the condition between November 2023 and October 2025, with 12 involving the affected 2022 SUV models.

On February 5, 2026, GM officially authorized a safety recall.

Recall Remedy: What Dealers Will Do

To correct the problem, GM dealers will:

  • Install updated Transmission Control Module (TCM) software
  • Improve monitoring of valve performance and wear
  • Perform repairs

Owner notification letters are expected to be mailed beginning March 30, 2026.  GM Recall Number: N252536750 ; NHTSA Campaign Number: 26V-085.

What Owners Should Do Now

If you own one of the affected vehicles:

  1. Watch for recall notification letters in the mail.
  2. Contact your local GM dealership to confirm recall eligibility.
  3. Schedule the software update as soon as possible.
  4. Pay attention to harsh shifting or unusual transmission behavior and seek service immediately if symptoms appear.

Final Thoughts

Full-size SUVs like the Tahoe, Yukon, and Escalade are often used for family transportation and long-distance travel, making drivetrain reliability especially important. While GM reports that rear wheel lockup events are rare, the potential safety risk is significant enough to warrant immediate attention.  If your vehicle is included in Recall 26V-085, scheduling the repair promptly is the safest course of action.

A critical issue affecting the transmission valve body of certain Ford Bronco, Explorer, F-150, Mustang, Ranger, and Lincoln Aviator vehicles can cause reverse gear failure or unexpected forward movement while in reverse or neutral gear. This problem could be a significant safety risk to drivers and passengers.

According to Ford, the issue is attributed to an incorrectly machined transmission valve body, specifically the Outer Valve Body (OVB) of the transmission main control. The machining tool used during production did not maintain proper specifications, resulting in out-of-specification dimensions that can prevent the vehicle from entering reverse gear when commanded by the gear shift module.

Symptoms of the problem include no reverse motion when the gear selector is in reverse, and in some cases, the vehicle may move forward with the gear selector in either reverse or neutral position. The Malfunction Indicator Light (MIL) and Wrench light will illuminate on the dashboard when this malfunction occurs.

The recall affects vehicles, including:

  • 2024-2025 Ford Bronco
  • 2025 Ford Explorer
  • 2024-2025 Ford F-150
  • 2025 Ford Mustang
  • 2024 Ford Ranger
  • 2025 Lincoln Aviator

Ford’s investigation into the matter began in February 2025, after a transmission failure was reported on a 2025 Mustang at the Flat Rock Assembly Plant. The company subsequently issued a Stop Ship order for affected models and launched an analysis of the suspect transmissions.

Using advanced data analytics, including Machine Integrated Learning and Optimization (MILO) modeling, Ford identified individual Outer Valve Body units that were likely to experience this condition. The company then conducted evaluations of vehicles equipped with suspect parts and confirmed the symptoms reported by customers.

As of February 21, 2025, Ford had received five warranty reports related to this issue. On March 7, 2025, the company’s Field Review Committee approved a field action, which includes replacing the transmission main control valve body.

Ford has notified owners of affected vehicles and has begun repairing the transmissions. The recall is identified as Ford’s number 25S19 and NHTSA Campaign Number 25V-164.

This recall highlights the importance of rigorous quality control measures in the automotive manufacturing process. The issue serves as a reminder that even minor defects can have significant consequences on vehicle safety and performance.

GM Wheel Lock-Up From Transmission Control Valve Defect

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.
