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.

NHTSA closes 4-year GM investigation, issues common sense advisory [w/video]

Since January 2011, the National Highway Traffic Safety Administration has been investigating a possible problem with corroding brake lines in General Motors' GMT800-platform models, like the Chevrolet Silverado and Suburban and GMC Sierra, in states with salt on their roads in the winter. However, as opposed to launching a full recall of millions of vehicles, the government is issuing a common-sense safety advisory to all drivers in snowy states to keep their vehicle's undercarriage clean. It even has a video explaining things. "Older-model vehicles, often driven in harsh conditions, are subject to corrosion over long periods of time, and we need owners to be vigilant about ensuring they, their passengers, and others on the roads are safe," said NHTSA Administrator Mark Rosekind in the announcement of the end of the investigation. The agency was clear in its report that "brake line corrosion seen in the GM vehicles was not unique," and the government "has not identified a defect that would initiate a recall order." Instead NHTSA is advising drivers, especially those of vehicles from before 2007, to wash their vehicle's undercarriage in the winter and spring to remove salt or other de-icing chemicals. It also recommends regular checks by a mechanic to make sure everything is in proper order. According to the investigation documents, for just the GMT800 platform models, NHTSA found 3,645 complaints of brake line corrosion, which included allegations of 107 crashes and 40 injuries. The issue was found to be more common in vehicles over 10 years old. GM has released a statement (embedded below) that the company "supports the consumer advisory from NHTSA urging regular maintenance and care of brake lines on older vehicles." NHTSA Closes Investigation into Brake-Line Failures NHTSA 13-15 Thursday, April 9, 2015 Agency issues safety advisory on preventing undercarriage corrosion WASHINGTON – The Department of Transportation's National Highway Traffic Safety Administration (NHTSA) today issued a Safety Advisory and consumer video encouraging owners of model year 2007 and older trucks, SUVs and passenger cars to inspect brake lines and thoroughly wash the underside of their vehicles to remove corrosive salt after the long winter in order to prevent brake-line failures that increase the risk of a crash.

Next-gen Chevy Silverado and GMC Sierra may use carbon fiber

It's been generally accepted that the next generation of full-size GM trucks will use some sort of strong, lightweight material for the beds while retaining steel for the cab. While aluminum seems like the most obvious choice, according to Automotive News, the Chevy Silverado and GMC Sierra will incorporate both aluminum and carbon fiber in their beds. The publication cites sources from within GM, though it seems the introduction of this comparatively exotic material mix is still a few years off. While carbon fiber is both stronger and lighter than steel and aluminum, it takes significantly more time and money to produce, essentially relegating the material to small-volume cars. The main benefit for trucks is the resulting reduction in weight to improve fuel economy without sacrificing the tough, rugged capabilities truck buyers expect. The Ford F-150 made the switch to aluminum for the 2015 model year and it's proved highly successful. It seemed like it was only a matter of time before the competition followed suit. Automotive News says that the next-gen trucks will launch with aluminum beds and that it will take a couple of years before we'll see any carbon fiber incorporated into the design. Even then, only look for the composite material on higher-trim models, with a trickle down to lower-spec trucks possible further in the future. In 2011, GM announced it was working with Japan-based Teijin Limited on a carbon fiber reinforced thermoplastic. There's a good chance that material's introduction will be on trucks.
