GM recalls full-size truck, SUVs and vans over faulty shifter mechanism

Twelve different General Motors vehicles from the 2013 model year, up to 54,686 units in total, are being recalled over two potential issues with their steering columns. The models in question, all full-size trucks, SUVs or vans, are the: Cadillac Escalade, Escalade ESV, Escalade EXT, Chevrolet Avalanche, Express, Silverado, Suburban, Tahoe, and GMC Savana, Sierra, Yukon and Yukon XL.
The affected vehicles were built with a fractured parking lock cable or "a malformed steering column lock actuator gear in the lock module assembly." As a consequence, they could shift out of park without the brake pedal being applied or with the key removed or in the off position.
A bulletin from the National Highway Traffic Safety Administration indicates that the recall should begin on January 17. GM will notify owners, at which time they can take their vehicles to their dealers for repair free of charge. Have a look at the bulletin below for more information.

'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).

Autoblog's Editors' Picks: Our complete list of the best new vehicles

It's not easy to earn an “EditorsÂ’ Picks” at Autoblog as part of the rating and review process that every new vehicle goes through. Our editors have been at it a long time, which means weÂ’ve driven and reviewed virtually every new car you can go buy on the dealer lot. There are disagreements, of course, and all vehicles have their strengths and weaknesses, but this list features what we think are the best new vehicles chosen by Autoblog editors. We started this formal review process back in 2018, so there's quite of few of them now. So what does it mean to be an EditorsÂ’ Pick? In short, it means itÂ’s a car that we can highly recommend purchasing. There may be one, multiple, or even zero vehicles in any given segment that we give the green light to. What really matters is that itÂ’s a vehicle that weÂ’d tell a friend or family member to go buy if theyÂ’re considering it, because itÂ’s a very good car. The best way to use this list is is with the navigation links below. Click on a segment, and you'll quickly arrive at the top rated pickup truck or SUV, for example. Use the back button to return to these links and search in another segment, like sedans. If youÂ’ve been keeping up with our monthly series of the latest vehicles to earn EditorsÂ’ Pick status, youÂ’re likely going to be familiar with this list already. If not, welcome to the complete list that weÂ’ll be keeping updated as vehicles enter (and others perhaps exit) the good graces of our editorial team. We rate a new car — giving it a numerical score out of 10 — every time thereÂ’s a significant refresh or if it happens to be an all-new model. Any given vehicle may be impressive on a first drive, but we wait until itÂ’s in the hands of our editors to put it through the same type of testing as every other vehicle that rolls through our test fleet before giving it the EditorsÂ’ Pick badge. This ensures consistency and allows more voices to be heard on each individual model. And just so you donÂ’t think weÂ’ve skipped trims or variants of a model, we hand out the EditorsÂ’ Pick based on the overarching model to keep things consistent. So, when you read that the 3 Series is an EditorsÂ’ Pick, yes, that includes the 330i to the M3 and all the variants in between. If thereÂ’s a particular version of that car we vehemently disagree with, we make sure to call that out.
