General Motors admits their estimated gas mileage for certain 2016 SUVs was a bit too optimistic. To make up for the snafu, the automaker will pay up or offer warranty extensions to 135,000 owners, including those with an Acadia.

In May 2016, GM told its dealers to stop selling 60,000 vehicles after discovering the discrepancy while working on the labels for the 2017 model year. The window stickers show estimates 1-2 miles per gallon higher than they should.

The Compensation Offer

GM plans to handle compensation to 2016 Enclave owners in one of two ways:

  1. They will offer owners debit cards of $450–$900, or
  2. Owners can opt out of the debit cards and choose a warranty extension instead. The extension is a boost from 36 months / 36,000 miles to 48 months / 60,000 miles.

The compensation was calculated using the estimated cost of gas ($3/gallon) and the average mileage driven (15,000 miles/year).

Generations Where This Problem Has Been Reported

This problem has popped up in the following GMC generations.

Most years within a generation share the same parts and manufacturing process. You can also expect them to share the same problems. So while it may not be a problem in every year yet, it's worth looking out for.

  1. Back in May GM admitted that they overstated the fuel economy on some 2016 SUVs

    and offered a compensation program as a sorry 'bout that. Owners received somewhere between $450 to $1500, based on a few factors, for their troubles. But that wasn't enough for some.

    A new lawsuit wants GM to pony up more cash for the decreased resale value of the 2016 Chevy Traverse, Buick Enclave, and GMC Acadia.

    "The GM lawsuit says consumers who purchased those SUVs believed the vehicles were EPA-rated at 17 miles per gallon in city driving and 24 miles per gallon on the highway, resulting in a combined rating of 19 mpg. However, the plaintiffs say the Traverse, Enclave and Acadia are in fact rated at 15 mpg in city driving and 22 mpg on the highway, resulting in a combined rating of 17 mpg."

    Listen, I get it – GM advertised one thing and produced another. That's no good. But if someone is looking to buy a large used SUV, then I'm not convinced that 2 MPGs are a deal breaker.
