A US car manufacturing giant has agreed to send $150 million to customers to settle accusations that certain vehicles were sold with defective engines.

According to the newly updated settlement portal, General Motors will provide compensation to affected owners and lessees for issues related to excessive oil consumption in vehicles equipped with LC9 engines.

The payout will go to customers in California, Idaho and North Carolina.

The lawsuit alleges GM was aware of a defect triggered by excessively worn piston rings, which leads to excessive oil consumption, spark plug fouling, rough idling, rough acceleration, check engine light activation, engine shutdown commands, oil loss and potentially permanent engine damage or shutdown.

Although GM has decided to settle, the company firmly denies any wrongdoing or liability and rejects the notion that any vehicles connected to the case are defective.

The lawsuit alleges certain 2011 through 2014 models are defective, including Chevrolet Avalanche, Chevrolet Silverado, Chevrolet Suburban, Chevrolet Tahoe, GMC Sierra, GMC Yukon and GMC Yukon XL.

Eligible owners or lessees may automatically receive a pro rata payment estimated at a minimum of $2,149).

North Carolina class members must submit a required Identification Form to confirm eligibility, while others generally need not file a claim unless notified.
