GM Issues Stop Sale on SUVs

General Motors is telling its dealers to hold off on selling 2016 model-year Buick Enclave, Chevrolet Traverse, and GMC Acadia SUVs until they get new window stickers with corrected fuel economy ratings, according to Edmunds.com.

The stickers currently affixed to these vehicles overstate fuel economy by 1-2 mpg, so the automaker is readying the corrected stickers for delivery to dealer lots. The 2016-MY Buick Enclave, Chevrolet Traverse, and GMC Acadia are rated at 15 mpg for city driving and 22 mpg for the highway, according to the U.S. Environmental Protection Agency.

The stop-sale order affects about 60,000 vehicles at dealerships.

GM has already notified the EPA about the correction and is also working to correct advertising and marketing materials.

"This error was discovered as GM engineers worked on the 2017 model year labels, and was quickly reported to EPA," said Robert E. Wheeler, communications manager for General Motors fleet customer care and aftersales. "We continue to work with the EPA on this issue."

GM will also contact owners of the 2016-MY SUVs to inform them of the correction. The label error has no effect on the safety or operation of the vehicles involved.

Meanwhile, a Consumer Reports article is raising questions about whether such fuel-economy corrections should be made to cover 2 million additional GM vehicles. The automaker, however, hasn't announced any such plans.
