GM said it is reviewing all of its products after a federal agency ordered the recall of some of its vehicles over a leaking coolant system.

The federal agency on Friday issued a nationwide recall notice for about 2.4 million vehicles, including about 500,000 sedans and about 250,000 coupes, according to a statement from the National Highway Traffic Safety Administration.

The agency said the coolant leak occurred on a vehicle with a G12 engine, the highest engine rating available on the new model, the GMC Sierra.

The affected vehicles include the Chevrolet Tahoe, Tahoe HD, and Sierra.GM said in a statement that it is working with federal regulators and its suppliers to resolve the issue.

The agency did not provide details on the cause or severity of the leak.

GM said the leak happened in a GM factory.

The statement said the agency was still evaluating the details of the recall.

It was not immediately clear how many of the vehicles were affected.

The National Highway Safety Administration issued a warning late Friday about a potential safety problem in the coolants used in the new generation of the GM C7 and C8.

The NHTSA said a small percentage of the coolANTs in the C7 could fail in hot weather and could cause a leak in a vehicle.

A leak could result in engine failure and a fire, the agency said.

The notice said the C8 coolant could fail and cause a safety hazard if a small amount of coolant was spilled into a hot-air balloon.

The warning came after the NHTSC said the safety risk posed by a leak of a small part of the cooling system could not be ruled out.
