GMC Terrain headlight recall fix is a sticker

This GMC Terrain recall over a headlight issue has gone from fascinating to absurd. It started when GMC discovered the headlights on the 2010-2017 Terrain were out of compliance with Federal Motor Vehicle Safety Standards (FMVSS). A pinpoint of low-beam light was being reflected off the high-beam reflector. This bounced a tiny sliver of bright light up into the trees and the sky beside the road, not into oncoming traffic. GMC did the right thing, reporting the noncompliance to the National Highway Traffic Safety Administration. Because the sliver of light was coming from the low beams and was four times brighter than the maximum allowable low beam brightness, the NHTSA told GMC to recall 740,581 units of the SUV. GMC asked for an exemption, admitting the bright spot could cause glare while noting the errant beam didn't affect other road users. The automaker hadn't received any complaints, only a comment from one owner saying the lights put a bright spot in the trees on the other side of the road. The NHTSA denied the request. GMC began notifying owners in April that they'd need to come in for a fix once a fix had been developed. That's the fascinating part. The absurd part, which Tire Meets Road uncovered, is that the fix is a "Headlamp Applique Kit." Which is a piece of frosted tape applied to the outside of the headlight that lets low-beam light through and tamps down any potential glare from the caroming beam. Notice that the parallelogram of frosted tape matches the L-shaped frosted area along the inside of the headlight housing. That portion was already a feature of the lamp, as can be seen in our 2016 Terrain Denali Quick Spin. The repair needs a trip to the dealer for a tech to place a positioning template over the headlight and put the applique kit in the proper spot. GM's instruction kit says the whole thing should take 0.2 of an hour, or 12 minutes—about the time it it would take to get checked into and out of the dealership service department. Owners aren't impressed, some calling the fix unnecessary and ridiculous, and the tape should make it clear that GMC feels the same way. Some owners have said they're going to skip the recall. Those drivers will find that just as GMC couldn't escape the legal ramifications, neither can they. Local motor vehicle bureaus keep track of recall compliance.

These are the 'Greenest' and 'Meanest' cars in 2015

As has become tradition, the American Council for an Energy-Efficient Economy (ACEEE) has come up with a ranking of what it refers to as the "greenest" cars of 2015, and, by way of contrast, a list of the so-called "meanest" cars, so those who value eco-friendliness over all else can choose which vehicles they should or should not consider buying. As you may expect, electric cars make up the majority of the greenest cars on the list, but, perhaps surprisingly to many, the Tesla Model S didn't make the cut. It's worth noting, too, that where the electricity an owner uses to charge their electric vehicle has a big impact on its overall environmental impact. "A car that is charged using electricity generated from natural gas or renewables is going to have significantly less impact on the environment than one charged on a coal-heavy grid," says ACEEE lead vehicle analyst Shruti Vaidyanathan. The ACEEE's list for 2015 looks very different than it did in 2014. It's an interesting collection, though – and we're sure this goes without saying, really – we'd recommend doing a bit more research into each vehicle and how it might fit into your daily life before making any purchase decisions.

Supercharged 2015 GMC Yukon Denali sounds evil, runs 0-60 in 4.5 seconds

Speeding along in a sports car is undoubtedly a ton of fun, but some owners need the ability to carry a lot of people and their stuff and don't want to sacrifice the ability to put the power down. The tuners over at Hennessey have that demographic covered with their growling, supercharged power kits for the GMC Yukon Denali. The upgrades come in three forms for the SUV's 6.2-liter V8: HPE550 with 557 horsepower, HPE600 with 605 hp and HPE650 with 665 hp. This video showcases the full-bore version, and this Denali can definitely hustle in a straight line. The power bump comes courtesy of a 2.9-liter supercharger, intercooler and high-flow cylinder heads to add over 200 horsepower compared to stock, and the final result is a bellowing SUV that rears up off he line to throw the driver back into the seat. The sprint to 60 miles per hour lasts just 4.5 seconds. Check out this hasty hauler in action in the video above.
