GM diesel pickups first to undergo extra EPA, CARB testing

The effects of Volkswagen's long-running diesel emissions evasion are starting to spill over to other automakers, but General Motors is taking things in stride. The 2.8-liter, four-cylinder Duramax in the 2016 Chevrolet Colorado and GMC Canyon is the first engine to get extra scrutiny by the Environmental Protection Agency and the California Air Resources Board, Automotive News reports. Rather than just the usual in-lab test, it's also being checked on the road. However, the extra evaluation shouldn't have any impact on when the trucks with his mill hit dealers later this fall. "We're in our final stages of the EPA certification, and our launch is on track," Chevy spokesperson Otie McKinley tells Autoblog. The four-cylinder diesel in the trucks makes 181 horsepower and 369 pound-feet of torque, and the automaker is touting low NOx production. In the announcement for the Colorado's specs, the company calls it "the cleanest diesel truck engine ever produced by General Motors." The tech includes exhaust gas recirculation to lower combustion temperatures and improve emissions. There's also a urea tank like on the bigger diesels for full-size trucks, and it gets refilled in time with oil changes. An indication on the instrument panel lets drivers know when that's needed, too. Even with the more demanding testing, the company doesn't seem too worried about the four-cylinder passing. "Part of our development process is on-road and off-road [laboratory] testing," Scott Yackley, Chevy Trucks assistant chief engineer, said to Automotive News. In the wake of the VW scandal, the EPA has pledged more rigorous testing. Before, on-road emissions evaluations were largely limited to heavy-duty vehicles, but the agency has decided to apply the checks more often to other models. There's also now greater cooperation with Canadian authorities.

Poor headlights cause 40 cars to miss IIHS Top Safety Pick rating

Over the past few months, we've noticed a number of cars and SUVs that have come incredibly close to earning one of the IIHS's highest accolades, the Top Safety Pick rating. They have great crash test scores and solid automatic emergency braking and forward collision warning systems. What trips them up is headlights. That got us wondering, how many vehicles are there that are coming up short because they don't have headlights that meet the organization's criteria for an "Acceptable" or "Good" rating. This is a revision made after 2017, a year in which headlights weren't factored in for this specific award. This is also why why some vehicles, such as the Ford F-150, might have had the award last year, but have lost it for this year. We reached out to someone at IIHS to find out. He responded with the following car models. Depending on how you count, a whopping 40 models crash well enough to receive the rating, but don't get it because their headlights are either "Poor" or "Marginal." We say depending on how you count because the IIHS actual counts truck body styles differently, and the Infiniti Q70 is a special case. Apparently the version of the Q70 that has good headlights doesn't have adequate forward collision prevention technology. And the one that has good forward collision tech doesn't have good enough headlights. We've provided the entire list of vehicles below in alphabetical order. Interestingly, it seems the Volkswagen Group is having the most difficulty providing good headlights with its otherwise safe cars. It had the most models on the list at 9 split between Audi and Volkswagen. GM is next in line with 7 models. It is worth noting again that though these vehicles have subpar headlights and don't quite earn Top Safety Pick awards, that doesn't mean they're unsafe. They all score well enough in crash testing and forward collision prevention that they would get the coveted award if the lights were better.

GM Canada recalls 159,240 GMC and Chevy trucks for faulty defroster circuit

General Motors is recalling more than 159,000 2014-2019 Chevrolet Silverado and GMC Sierra pickup trucks in Canada due to a potential fire risk. GM says the rear defroster circuit could overheat on trucks optioned with the power-sliding rear window. Thus far, there is no word on the recall's relation to U.S. vehicles. The recall, found by Automotive News, was posted to Transport Canada on June 28, 2019 with manufacturer recall No. N192220470. Included in the 159,240 vehicles are the 2014-2018 Silverado 1500, the 2015-2019 Silverado HD, the 2014-2018 Silverado LD, the 2014-2018 Sierra 1500, the 2015-2019 Sierra HD, and the 2014-2018 Sierra LD. The notice says the rear defroster circuit, specifically on trucks with the power-sliding rear window, could overheat. Because of its placement, this excess heat could cause melting, smoking, or possibly fire, in the worst case scenario. As of now, there is no official word when GM will initiate the recall and there is no official fix detailed just yet. GM suggests that owners, who will be notified by mail if their vehicles are affected, take their trucks to a dealer to remove the rear window defroster fuse as a stop-gap.  Automotive News contacted GM to find out if the problem is also found in trucks sold in the United States, but no definitive statement was made, as the investigation is reportedly ongoing. We will update this space if American vehicles are found to be included in the problem.
