GM Issues a 'Stop Sale' After Incorrect Fuel Economy Labels Found on Full-Size Crossovers

General Motors is in damage control mode following the discovery of incorrect fuel economy ratings on the window stickers of its 2016 full-size crossovers.

A “stop sale” order was issued to GM dealers on Wednesday after EPA labels on GMC Acadia, Chevrolet Traverse and Buick Enclave vehicles were shown to overstate mileage by one to two miles per gallon, Automotive News reports.

Nearly 60,000 vehicles are sidelined until replacement Monroney stickers arrive at dealerships between today and Tuesday.

There’s no evidence that points to intentional deception, but it’s a bad time for any automaker to face a misleading fuel economy controversy, given the scandal currently consuming Mitsubishi in its home country.

GM spokesman Tom Wilkinson told Automotive News that the mistake can be pinned on a faulty “data transmission,” adding that GM informed the Environmental Protection Agency as soon as the issue was discovered. The EPA has since requested all information pertaining to the issue.

A memo from GM to dealers stated an “inadvertent error” led to the wrong figures appearing on the labels.

The EPA rating for all-wheel-drive versions of the vehicles should be 15 mpg in the city, 22 highway, and 17 combined, but the incorrect labels added 2 mpg to each figure. Front-drive models added 1 mpg to the actual combined rating.

The issue is more than just bad optics for GM — it means tens of thousands of vehicles were bought under false assumptions, and those customers won’t see the gas mileage their window sticker promised.

To keep the peace, the automaker might have to reimburse customers for the difference in mileage, though for now, GM is notifying buyers and creating a plan to deal with any backlash. With the EPA still looking into how the figures made their way onto stickers, there’s no word yet on penalties.

Wilkinson said that unspecified changes made to the models for the 2016 model year required the printing of new EPA ratings.

    It's interesting to see which other corporations hold 10% or 15% interests in the big brands. You may also have observed over the years, big brands buying out alternative fuel competitors, supposedly as exciting ways to get 'in' on new tech, and then slowly folding them. How about "experienced in energy" double agent executives gaining top positions at alternative energy powerhouses that subsequently suffer massive performance failures? It can be no coincidence these GM vehicles use the same amount of fuel as they did 40 years ago. It must be designed that way as part of a strategic business model that takes a lot of effort to make happen. Neither do I expect that a systematic fraud which conveys a competitive advantage in the market place is the fortuitous result of bumbling fools at the printing house. But then I say Lewis Hamilton could not have had - cracked brake pad, loose fuel line, 2 start mode glitches, 2 computer failures; while his team mate had none. The odds of that happening randomly are 0.1%. Call Mulder and Scully.

      Right, because cars of 40 years ago had the same safety and luxury features that they do today (power everything, ABS, airbags, aircon on almost every vehicle, larger brakes, larger wheels/tires, infotainment systems, etc). Not to mention that cars that got the same MPG as, say, a Cruze or Sonic, etc had far less power and were super strippers with nothing in the way of comfort/convinence/safety features. They also drove like horrible little roachmobiles and had ghastly crash protection. If you took someone from 1976 who drove an economy car and put them in a modestly-equipped 2016 Cruze, theyd think you handed them they keys to an exceptional small Cadillac. Hell, the Cruze probably has similar HP as an emissions-strangled '76 V-8 Caddy. So, how many 1976 Chevys got over 40 MPG like the Cruze (some models IIRC), Sonic or Spark? How about mid-30s like a Malibu? And what kind of power did they make compared to 2016s? What 1976 full size truck broke 25 mpg? Take off your tin foil hat and let the chemtrails do their job.

    Is this a violation or error??? The article alludes to error, but I wonder. Was their a shortage of labels? If a shortage existed then it's odd how the EPA stickers displayed better FE. Fine them for being deceitful and so stupid, like VW.

      @JohnTaurus Nice revisionist take on things. Crooks never expect to get caught (assuming the fine is greater than the benefit of the crime), but once outed they appear to do clean up like non crooks do. I'm not saying gm is guilty, just that there needs to be s deep dive to prove that they are not playing again.

Now, Tesla is coming around and biting him on the arse!!In the car business, you need to keep you finger on the pulse. Momentum will only carry you so far. If in doubt, think Lordstown and Fisker. He thinks technology will solve his problems. However, Telsa has moved from premier product to commodity with other manufacturers entering his exclusive domain. Time for Elon to fly back to Tesla HQ and come up with a long term plan. 🚗🚗🚗
  • Irvingklaws Anymore seems I want a color that is not black, white, red, or some shade of silver/gray. Though I coveted them when I was younger, I also seem to have developed an aversion to all-black interiors. I have a deep negative reaction to any vehicle identifying as "triple black". Don't even get me started on black wheels...I'm not the only one. We're looking to replace my wife's silver CX-5 and one of her few non-negotiable prerequisites is that it be "a color" not in the aforementioned list. It's looking like a Cascade Green Forester with a light gray interior is in her future.
