GM to recall certain trucks, SUVs after NHTSA probed 877K vehicles for engine failure

By Sasha Richie | Dallas Morning News (TNS)

General Motors will voluntarily recall certain trucks and SUVs after nearly 900,000 vehicles were investigated for engine failure in January, the company confirmed in a statement.

The recall affects 2021-24 model year Chevrolet Silverado 1500s, Tahoes, Suburbans, GMC Sierra 1500s, Yukons, Yukon XLs, Cadillac Escalades and Escalade ESVs that are equipped with GM’s 6.2L L87 engine.

The National Highway Traffic Safety Administration has not yet announced the recall or published its recall summary.

GM is recalling the vehicles “to resolve manufacturing issues affecting some engines,” the company’s statement said.

“The safety and satisfaction of our customers are the highest priorities for the entire GM team, and we’re working to address this matter as quickly as possible,” the statement continued.

In January, the NHTSA announced a preliminary investigation into certain GM trucks and SUVs after receiving 39 complaints of an engine rod bearing failure leading to either engine seizure or breach of the engine block by the rod.

No crashes or injuries had been reported due to the issue, but the NHTSA warned that “Failure or malfunction of the engine results in loss of motive power of the vehicle, which may lead to an increased risk of a crash resulting in injury and/or property damage.”

January’s investigation targeted an estimated 877,710 vehicles, including 2019-24 model year Chevrolet Silverados and GMC Sierras, and 2021-24 model year Chevrolet Tahoes, Chevrolet Suburbans, GMC Yukons and Cadillac Escalades.

With the recall affecting a narrower scope of vehicles than the investigation, the number affected should be a decent amount lower. The precise estimate for how many vehicles are recalled will be confirmed by the NHTSA’s report.

To address the engine issue, GM dealers will inspect and, as necessary, repair or replace the engine, according to GM. Vehicles that pass inspection will be provided a higher viscosity oil, which also requires a new oil fill cap, an oil filter replacement, and an owner’s manual insert.

Arlington Assembly, the GM plant that employs over 5,000 people in D-FW, is where many of the to-be-recalled vehicles rolled off the line.

However, as previously reported, the engines themselves come from other manufacturing plants in North America. In addition, quality control procedures in place at Arlington Assembly would not have caught the engine bearing issue, as it only manifests after a certain number of miles driven.
