One of Louisiana’s Most Popular Trucks Is Being Recalled – Here’s Why

BATON ROUGE, La. (KPEL News) - Louisiana drivers who own certain GM pickup trucks and SUVs may need to take action soon.

General Motors (GM) has announced a recall of nearly 462,000 diesel-powered Chevrolet Silverado, GMC Sierra, Cadillac Escalade, Chevrolet Tahoe, and other SUVs and trucks produced between 2020 and 2022.

The recall stems from a potential defect in the transmission control valve, which can lead to the rear wheels locking up unexpectedly, increasing the risk of a crash.

Why Are These Vehicles Being Recalled?

GM's recall report reveals that excessive wear in the transmission control valve can cause a fluid leak, leading to a pressure drop and eventual valve malfunction. This wear can cause the rear wheels to lock momentarily, which could cause drivers to lose control of the vehicle. Although GM has documented minor injuries associated with the defect, none have resulted from actual crashes. Louisiana drivers should take this seriously to avoid potential accidents on local highways and rural roads.

What Vehicles Are Affected?

The recall covers specific models of GM’s popular trucks and SUVs:

• Chevrolet Silverado 1500, 2500, and 3500 (2020–2022)
• GMC Sierra 1500, 2500, and 3500 (2020–2022)
• Cadillac Escalade and Escalade ESV (2021)
• Chevrolet Tahoe and Suburban (2021)
• GMC Yukon and Yukon XL (2021)

This recall exclusively involves diesel models, as those with gasoline engines have a different transmission and are not affected.

What Are the Warning Signs?

Drivers may notice some warning signs before a lock-up occurs. According to GM, signs can include:

1. Harsh or uneven shifting: The vehicle may feel like it’s shifting roughly, which can indicate the valve is wearing out.
2. Delayed acceleration or sluggish propulsion: The recall software update will limit vehicles to fifth gear if wear is detected, making the vehicle noticeably slower to respond.

GM's Safety Solution

GM will install new software in affected vehicles that actively monitors transmission performance. If excess wear is detected, the system will restrict the vehicle’s transmission to fifth gear to prevent the lock-up condition, helping reduce the risk of accidents. Additionally, if this software detects valve wear, a service engine light and a "reduced propulsion" warning will appear on the dashboard, alerting the driver to seek service.

How to Check if Your Vehicle Is Included

Louisiana owners can check their vehicle’s recall status through the National Highway Traffic Safety Administration (NHTSA) website using their Vehicle Identification Number (VIN). GM will begin notifying affected vehicle owners by mail on December 9, 2024. Louisiana GM dealerships will also have updated information, and many offer free recall inspections and repairs for vehicles included in this recall.

Timeline of GM’s Investigation

GM began investigating this issue after receiving reports of rear-wheel lock-up incidents. In July 2024, GM noted over 1,800 instances of wheel lock-up in these vehicles, including cases where minor property damage occurred. GM has since determined that transmissions in certain diesel-powered models are prone to wear, which can lead to these issues.

Importance of Addressing Vehicle Recalls in Louisiana

Louisiana residents, especially those who rely on GM pickups and SUVs for their durability, should consider addressing this recall as soon as possible. The rear-wheel lock issue poses a risk, particularly in wet or icy road conditions. Taking immediate action can help ensure vehicle safety for Louisiana families and contribute to safer state roads.

Next Steps for Louisiana Drivers

1. Look for a Letter: GM will mail letters to affected owners by December 9, 2024.
2. Schedule a Service Appointment: Once you receive the recall notice, contact your local GM dealership in Louisiana to schedule a free inspection and software installation.
3. Stay Updated on Recalls: Regularly check for recall updates through GM or NHTSA to ensure vehicle safety for you and your family.

If you’re driving a diesel-powered GM truck or SUV in Louisiana, this recall could affect you. GM’s proactive steps can protect drivers from the risks associated with rear-wheel lock-up issues.
