Why didn't GM recall fire-prone Hummers earlier?

As early as 2009, motorists reported fires in the Hummer H3. In a complaint filed that March with the regulatory agency in charge of vehicle safety, one motorist said they leaped into a smoldering vehicle and drove it away from gas pumps moments before it was engulfed in flames. Three months later, another motorist described how a fire spread from behind the glove box and consumed their H3. Dozens of car owners filed similar complaints with the National Highway Traffic Safety Administration in the six years that followed, detailing car fires of varying severity that originated in the HVAC systems of their Hummer H3s. But General Motors didn't issue a recall for any of the affected cars until last week, prompting fresh questions about how the company treats safety concerns in the wake of an ignition-switch flaw that went unaddressed for years and, at latest count, is responsible for killing at least 124 motorists. In recall documents filed with NHTSA last week, GM initially said it knew of three fires associated with the defect. Within hours, the company said it knew of 42 fires associated with the problem and three injuries sustained by vehicle occupants. A company spokesperson attributed the inconsistency to a "misstated" number in the original documents and that the higher number comes from NHTSA complaints, reports to GM and TREAD data. Beyond that discrepancy, the documents show General Motors, which has touted a revitalized attitude toward safety concerns since the ignition-switch recalls, did nothing upon determining there was a problem with the H3s. Prompted by two complaints the company received in September 2014, General Motors says it launched an internal investigation related to melting blowers in the HVAC system on December 8, 2014. In that investigation, the company says it confirmed a problem existed, finding that "mismatched electrical conductivity could result in overheating and melting of the blower motor connector module." But even with that conclusion, the company opted to close its internal investigation on April 29, 2015, without taking any action. It wasn't until NHTSA officials met with GM representatives in a meeting on June 18, 2015, that General Motors was prompted to reconsider.

GMC Hummer EV infotainment built with Unreal Engine used by 'Fortnite' and 'Rocket League'

We're only a couple weeks away from the reveal of the GMC Hummer EV truck and SUV. And we're expecting a lot of boasting about impressive capability and unique features. What we weren't expecting was for its infotainment system to be built on a video game engine. That's the news that has come out of Epic Games, creators of Unreal Engine, the basis of the Hummer's infotainment system. If you've been an avid video gamer anytime in the last 20 years, Unreal Engine should be recognizable. The first version of it powered Epic's "Unreal" and "Unreal Tournament" games, and more recent versions power multiplayer hits such as Epic's "Fortnite" and Psyonix's "Rocket League." The engine has been licensed out to countless other game developers for titles by both indie developers and large game companies. But its use in the GMC Hummer will be the first time it has powered a production car's infotainment system. This content is hosted by a third party.

Presumably it's a version of Unreal Engine 4, since Unreal Engine 5 hasn't been released yet. Also, while Epic released a trailer announcing the partnership and showcasing Unreal's 3D rendering and menu developing tools, it doesn't give us a peak at what the infotainment and instruments of the Hummer will look like. The company does tout fast boot-up times, powerful graphics, and over-the-air updates as useful features included with Unreal. But for a clear look at the final product, we'll have to wait for the October 20 reveal. Related Video:

Super Bowl car commercials: Follow along as we riff on them live

Join Autoblog editors Sunday starting around 6:30 p.m. ET as we react to all of the car commercials during the game. We know Hummer, Porsche, Hyundai and others will have splashy ads, and naturally, there's usually a few surprises. Whether you're a Chiefs or 49ers fan — or don't care about football — the commercials are always a highlight. And for us, the car spots are the most intriguing. Weigh in with your own thoughts in the comments section. Let's kick off.   FIRST QUARTER Editor-in-Chief Greg Migliore liveblogs the first quarter. F9 We'll count this as a car commercial. The latest edition of the Fast & Furious looks like it well, will have cars. We'll punt on further comment. PORSCHE I like it. Creative. Sort of a Night at the Museum feel. The guards stage a theft and then a car chase. The Taycan looked good. Get fired up — the future for Porsche is electric. The spot is meant to illustrate how fun that can be. I don't need any convincing.    SECOND QUARTER Associate Editor Byron Hurd is liveblogging the second quarter.  HYUNDAI Hyundai checked in super early with their Sonata "Smaht Pahk" commercial, which manages to score points for being both cute and clever while also being a fairly good commercial in a vacuum. We saw it last week, so there were no surprises here, but we enjoyed it nonetheless.  Fun note: If you go to the Sonata landing page on Hyundai's web site, you can choose "plain old English" or "the Boston way" for your language; the latter will translate the page. Enjoy.  FORD Hi ho, West Coast Editor James Riswick here. Apparently, the guys in Detroit didn't get the Mustang Mach E ad featuring Idris Elba and a whole boat load of awesome old Mustangs. Pretty sure it's bound to be viewed the exact same way as the car itself: traditionalists will be aghast, while non-car people will be intrigued by a new, all-electric, crossover version of one of the few cars they've heard of.  GENESIS They're coming more rapidly now. Genesis gets some love thanks to Chrissy Teigen and John Legend; this was another known quantity, but Hyundai's luxury brand managed another solid entry here thanks to its choice of stars. Teigen and Legend got the chance to throw back to the latter's "Sexiest Man Alive" honors, which Teigen often teases him for. Another solid all-around spot.  GMC/HUMMER Are there just no surprises left? Don't tell me; I know the answer. LeBron James fronts the revived Hummer, which will be an EV sold as a GMC.
