GM recalls nearly half a million more Cadillacs, GMCs, and Chevy trucks

General Motors issues recall due to transmission valve failure

Hot on the heels of its last recall, which occurred only a short while ago due to faulty electronic brake control software, General Motors has just issued a new recall via the National Highway Traffic Safety Administration. The recall affects certain Chevrolet Silverado, Tahoe, Suburban, GMC Sierra, and Cadillac Escalade models produced with diesel engines.

The good news, relatively speaking, is that this particular recall only affects vehicles equipped with diesel engines. The bad news is that even with that said, the total number of potentially affected units is still 461,839.

The problem:

It seems that the transmission control valve on any of these pickup trucks and SUVs can fail, causing the rear wheels to lock up and potentially catastrophic consequences.

The solution:

Owners will have to contact dealerships to schedule a time to bring their truck or SUV back to the dealership. From there, GM will first install new transmission control module software free of charge. Then, if the remedy software identifies a defective TCM, General Motors will offer a “special coverage program” to pay for transmission repairs and install a functioning control valve.

Potentially affected vehicles:

Cadillac Escalade – 2021

Cadillac Escalade ESV – 2021

Chevrolet Silverado 1500 – 2020-2022

Chevrolet Silverado 2500 – 2020-2022

GMC Sierra 2500 – 2020-2022

Owners will notified via snail mail beginning December 9, 2024, but may contact General Motors’ customer service at 1-800-458-8006, Chevrolet customer service at 1-800-222-1020, Cadillac customer service at 1-800-458-8006, or GMC customer service at 1-800-462-8782 prior to that date using recall reference number N242454440.

In what feels like an almost monthly occurrence, Tesla has issued yet another recall on the heels of a Cybertruck recall earlier this month. These recalls add to Tesla's number one ranking of the total number of vehicles recalled for 2024, according to iSeeCars.com recall tally, which has now crested the 5.1 million mark (Ford currently sits at number two with just under 4.4 million).

This callback marks number seven for the futuristic SUV, and also includes certain Model Y and certain Model 3 vehicles, totaling 694,304 potentially affected cars and trucks.
