GM recalling 250,000 SUVs over door electronics

After a door-fire investigation that dates back to February, the National Highway Traffic Safety Administration has officially announced a recall today that affects around 250,000 General Motors SUVs for a faulty driver's door module. The recall applies to the Buick Rainier, Chevrolet Trailblazer, GMC Envoy, Isuzu Ascender and Saab 9-7X from the 2006 and 2007 model years, as well as the 2006 Chevrolet Trailblazer EXT and GMC Envoy XL for vehicles sold and/or registered in the Snow Belt.
Road salt use in these midwestern and northern states can lead to corrosion of the driver's door module on these GMT360 and GMT370 vehicles, which allows water to come in contact with the circuit board. If shorted out, the vehicle's power door locks and power windows will not work, and could possibly lead to overheating and, in some circumstances, a fire. No official word on how many total vehicles caught on fire, but back in June, 28 fires had been reported to the government agency. A fix for the problem is still being worked out, but all affected vehicle owners will be notified by GM.

'Killing a Duramax' Gale Banks YouTube series methodically tunes a diesel to death

Learning or perfecting a skill by watching YouTube videos is known as attending YouTube University. GM Authority picked up on one of the video site's more fascinating courses, hosted by Gale Banks; in a fair world, he should be referred to as Professor Banks when it comes to diesel engines and truck tuning. A few months after GM introduced the updated L5P 6.6-liter Duramax diesel V8 in the 2020 Chevrolet Silverado HD and GMC Sierra HD that ships with 454 horsepower and 910 pound-feet of torque, Banks decided he wanted to methodically tune the engine to death. The purpose of the resulting series, called "Killing a Duramax," is to push more power out of the engine in order to discover which parts break and when — or, as Banks puts it, force-feed the Duramax "until the crank hits the street and the heads hit the hood." With that knowledge, Banks can figure out all the weak points on his way to building what he calls a "Superturbo," that being a supercharged, twin-turbo race engine with more than 1,000 hp. What makes the series fascinating is Banks' knowledge, paired with the company's comprehensive iDash engine monitoring system that keeps tabs on a glut of parameters every step of the way. So for instance, you get Banks explaining the differences between inches of mercury and barometric pressure, how those are different from the water content of the air measured in grains, then showing those readouts on the iDash, then explaining in detail how they affect the air density in the Duramax system. The stock Borg-Warner variable turbo gets a lot of airtime — Banks accuses it of being "out to lunch" because he feels it's the weakest link on the engine. That turns into a turbo teardown and a deep explanation of performance pitfalls, such as when air pressure on the turbine begins to diverge from the boost pressure coming from the compressor. Banks says he can keep close tabs on where power's coming from, because the iDash monitors the horsepower contribution provided by the ambient air, the turbo, and the intercooler separately. The major changes so far are a stouter Precision 7675 turbo and TurboSmart wastegate (episode 5), a twin intake (episode 6), a custom liquid-cooled intercooler from a marine engine, a new GM oil cooler and synthetic oil (episode 10), and new injectors (episode 11).

eBay Find of the Day: 1976 GMC Motorhome is a jolly green giant

If you have a need to relive the 1970s, then here is the vehicle for you. This groovy blast from the past is a 1976 GMC Motorhome currently for auction in Florida on eBay Motors, and it is one green machine - just not in the modern sense.
The seller claims that this beast has had just two owners and has covered a mere 61,308 miles in its decades on the road. It's reportedly never been restored or repainted and comes with all of the necessary books and manuals. A 7.5-liter (455-cubic-inch) Oldsmobile V8 with a three-speed Turbo-Hydramatic automatic transmission powering the front wheels propels this far-out RV, and the double set of rear wheels out back use a self-leveling air suspension to provide a cushy ride.
The purported low miles and good condition really make this GMC a stand out, though. The exterior combination of lime stripes and beige with just a touch of green is like nothing else on the road today. Plus, the polished bumpers and wheels make it all pop. Inside, it's even better with monochromatic green upholstery and shag carpet. It features everything you'd ever need on a long trip, including a bathroom, kitchenette and lots of seating. The only hint of modernization is an HD TV next to the stove, but its size is a perfect fit for the hole there.
