GM warning 800,000 owners that their cars may need oil changes more frequently than they say

The days of changing your engine oil every 3,000 miles are long gone thanks to most cars having automatic oil monitoring systems, but about 800,000 General Motors vehicles apparently have incorrect monitoring software that is leading to premature engine component wear. According to Autoweek, certain 2010-2012 Buick LaCrosse, Regal, Chevrolet Equinox and GMC Terrain models equipped with 2.4-liter four-cylinder engines could be going too long in between oil changes resulting in a higher-than-normal number of warranty claims for the engine's balance chain. The balance chain links the balance shaft to the crankshaft, and a worn one can produce higher noise levels.
As a fix, GM dealers will be reprogramming the software for the monitors in an effort to reduce the interval between oil changes, which varies based on driving habits and conditions. Through February 2015, the software update will be done at no cost to vehicle owners, but since this is not a recall, after that point, it will be up to the discretion of dealers as to whether or not they will charge for the service. What isn't immediately clear is whether GM plans on giving assistance to out-of-warranty customers who are experiencing engine issues from the worn chain.

2020 Chevy and GMC HD truck spy shots reveal LED lighting

With Chevy and GMC's 1500 series pickups just starting to roll into dealerships, our attention naturally turns to the Heavy Duty 2500 and 3500 series trucks. We've seen these HD trucks testing already, but thes latest spy photos give us our first good glimpse of the two HD trucks' headlights through some translucent camouflage, and their designs appear very interesting and quite different from each other. The 2020 Chevrolet Silverado HD looks to be getting a striking set of LED lights that flank the grille. A previously released teaser image of the truck shows that the front lighting elements are split by a bulky wing that branches out from a big, upright chrome face, and both top and bottom units seem to incorporate LED slashes. If you look closely at the images, you can easily make out the Chevrolet script cut into the grille's top edge. Amidst a bevy of Chevy test trucks was one lone GMC model in a dually configuration, and the Sierra HD also appears to have some LED accent lighting up front. Unlike the boomerang-shaped Chevy LEDs, GMC's version sports a shoulder-like right angle of light bars. Assuming these are production-level lighting units, it seems the Sierra HD will stick pretty close to the face of GMC's latest light-duty pickup truck. We're still waiting for confirmation on what range of powertrains will be available in GM's next-gen HD trucks, but we're sure there will be both gasoline- and diesel-burning engines on the ordering sheet. We expect to hear official details on the trucks sometime soon.

The Hummer EV Edition 1 is sold out and it'll be years before other trims arrive

When the 2022 GMC Hummer EV was revealed, GMC noted that there would be lower trims available. The company has since provided a few more details on those lower trims, which is helpful to know now that the only trim on sale next year, the Edition 1, was sold out in a scant 10 minutes. However, it's going to be a long time before they're all available.  The entry-level GMC Hummer EV is the EV2. This is the model that will start at $79,995, and unlike the Edition 1, it gets just two motors, one for each end of the truck, each with electronically locking differentials. Output is down to 625 horsepower and a torque rating of 7,400 pound-feet. Note that this and all other reported torque numbers are after the torque multiplication by the single-speed transmissions, hence the extremely high numbers. The company hasn't given torque numbers at the motors, which would be more comparable to other electric cars. Range is also reduced to 250 miles, probably due to a smaller battery pack. Fast charging is also restricted to 400-volt charging, so it won't be as fast as the higher trim models. The removable roof panels, retractable rear window, MultiPro tailgate, Super Cruise and 35-inch tires are standard. This model only gets fixed steel suspension and two-wheel steering. The EV2 will be the last of the trim levels to go on sale, with a target of spring 2024. Yes, as in 3.5 years from now.  The next level is the EV2X, which will be available a year earlier in the spring of 2023. It gets the same powertrain as the EV2, but adds 800-volt fast charging and a 300-mile range. It also gets the adaptive air suspension and four-wheel steering, plus the associated party tricks of Crab Mode and Extract Mode. This model costs $89,995. The earliest Hummer EV that isn't an Edition 1 and therefore not yet sold out will be the EV3X, the entry-level three-motor model. It goes on sale in the fall of 2022 at a price of $99,995. It's not quite as potent as the Edition 1, though, with an output of 800 horsepower and 9,500 pound-feet of torque. It also lacks the "Watts to Freedom (WTF)" launch control feature. But it does get torque-vectoring with the dual rear motors, which can also lock their speeds to be equal like with the mechanical locking differential at the front. The EV3X's range is 300 miles like the EV2X.  As for the Edition 1, it started $112,595 before it was sold out. Customers are to expect them in fall 2021.
