General Motors is currently working on a plan to compensate owners of the 2016MY large crossovers featuring window stickers with incorrect EPA ratings.

This initiative comes shortly after the first lawsuit over the issue was filed in federal court, as the company is trying to regain customers’ trust for what they’re calling an “inadvertent error.”

The models affected by this error were 170,000 examples of the 2016 Chevrolet Traverse, GMC Acadia and Buick Enclave, all of which had overstated their fuel economy figures by 1 to 2 mpg, according to GM insiders.

The American automaker is expected to communicate their plan to customers and dealers within a week.

In the meantime, GM was also hit with a prospective class-action lawsuit on Tuesday. The complaint alleges that GM concealed the actual fuel economy of the previously mentioned crossovers which led to customers having to overpay in order to purchase them.

The incorrect stickers read 17 mpg city/24 highway/19 combined, while they should have said 15 mpg city/22 highway/17 combined. The ratings for front-wheel drive models were also listed incorrectly at 12 mpg city/22 highway/18 combined.

In a statement to Autonews, a GM spokesperson said that the 2016 models in question were equipped with new “emissions-related hardware” which had to be tested and that “the fuel economy data from these tests were not captured in calculations made for EPA fuel economy labels… causing 2016 model year fuel economy numbers to be overstated.”
