General Motors is recalling almost 600,000 cars over engine problems.

These are all models which are equipped with a 6.2 litre V8 petrol engine produced between March 1 2021 and May 31 last year.

The recall covers a total of 597,630 vehicles.

This is comprised of 126,027 Cadillacs, 174,208 Chevrolets and 297,395 GMC cars.

The connecting rod and/or crankshaft engine components in these vehicles may have manufacturing defects.

These could cause engine damage and even failure in the models affected.

There are some warning signs to alert drivers that their engine may be about to conk out.

These may include a knocking or banging sound from the engine, or the ‘check engine‘ light turning on.

There could also be other performance issues such as irregular shifting, or engine hesitation and reduced speed.

Owners of the models mentioned above in the recall notice are advised to take their vehicles to a Cadillac, Chevrolet or GMC dealership.

Here, they will be offered an engine inspection and engine repair or replacement free of charge.

Vehicles that pass inspections will be able to receive a new oil filler cap, higher viscosity oil, oil filter replacement and an update to their owner’s manual, also free of charge.

The recall notice was first issued on April 24, and was reported to the National Highway Traffic Safety Administration in the US.

It estimates that 3% of all vehicles being recalled may have the disastrous defect.

This comes to a worrying estimated total of 17,929 cars being deemed to be at risk of engine damage or failure by GM.

The notice states: “Manufacturing records were used to determine vehicles equipped with the 6.2L V8 gas engine (RPO L87) built within the suspect manufacturing window.

“Engine teardown analysis identified two primary root causes, both of which are attributable to supplier manufacturing and quality issues:

“(1) Rod-bearing damage from sediment on connecting rods and crankshaft-oil galleries.

“(2) Out of specification crankshaft dimensions and surface finish.

“If the engine fails during vehicle operation, the vehicle will lose propulsion, increasing the risk of a crash.

“Vehicles outside of this window and vehicles equipped with other engines are not included in this recall.”

Notification letters are expected to be posted to the relevant car owners on June 9, 2025.
