GM Issues Stop Sale on 2016 Lambda Based Crossovers by Michael Accardi May 13, 2016May 13, 2016 Share Comments Thread The General has just instructed dealers to stop selling 60,000 Chevrolet Traverse, GMC Acadia and Buick Enclave crossovers, due to incorrect EPA labeling. GM says the overstated fuel-economy ratings were the result of an “inadvertent error” which resulted in fuel mileage ratings “1-2 MPG higher than it should have been,” according to an internal dealer memo obtained by Automotive News. “GM is stopping sale of the affected models until a corrected label is printed and affixed,” the memo reads. 59,823 vehicles are currently grounded at dealers across the country and they cannot be delivered until correct Monroney stickers arrive. It’s believed the correct documentation will begin arriving on Saturday and all of them should be available by Tuesday. The correct EPA ratings for AWD derivatives of the Lambda triplets are 15 mpg city and 22 mpg highway for a combined rating of 17 mpg. The incorrect label showed 17 city, 24 highway and 19 combined. The crossovers have been sold with the erroneous ratings since the ’16 models hit dealerships last fall. GM will notify customers of affected vehicles. No word yet on if GM will face government fines because of the error.
