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.

GMC shows how the 2022 Hummer could have looked even more futuristic

Excitement filled the room when GMC asked its designers to resurrect the Hummer in April 2019, but a tinge of uneasiness permeated the department after executives locked in an early 2020 unveiling date. Luckily, stylists knew what they wanted early on in the development phase, and preliminary design sketches give us a fascinating look at how they shaped the electric off-roader that ended up making its global debut online in October 2020. Hummer, the brand, unceremoniously shut down in 2010 after General Motors failed to sell it to the Chinese, but its design DNA was so strong that stylists were able to pick up where their predecessors left off. All of the sketches published on Instagram by the official General Motors Design account show a boxy truck with a tall front end, a short windshield, and a generous amount of ground clearance. These styling cues trace their roots to the AM General Humvee that entered production in 1984 and made its combat debut when the United States invaded Panama in 1989. Even the wildest drawings still depict a pickup that's immediately recognizable as a Hummer. Most of the early design sketches wear some variation of the seven-slot grille that characterized Hummer's production models; it's a styling cue that hints at a heritage shared with Jeep under the American Motors Corporation (AMC) umbrella. Oddly, none wear the round headlights seen on the H2, the H3, and the HX concept that nearly became the H4. Was GMC afraid that its Hummer would end up looking too much like a Jeep? And, at least one sketch shows a fold-down windshield, a feature that will not make it to the assembly line. Sketches never reach production without modifications made in the name of packaging and safety concerns, and the Hummer is no exception, but stylists did a good job of reinventing the brand's design language without copying or erasing the past. If the company had stuck around long enough to make a second- and a third-generation H2, odds are it would look a lot like the GMC-branded model that will enter production in a year. GMC remains on track to start 2022 Hummer deliveries in late 2021, though it told Green Car Reports that it still hasn't built a fully functional prototype yet. When it arrives, this outdoorsy pickup will land in a burgeoning segment of the truck market that numerous models (including the Rivian R1T and Ford's electric F-150) will also call home.

2021 GMC Terrain spied on GM's Proving Grounds

As the Chevrolet Equinox changes, so does the GMC Terrain. We saw shots of an updated Equinox not too long ago, and now our spy shooters have caught the GMC version of the crossover testing inside GM's Milford Proving Grounds. Similar to the Equinox, the Terrain is due for a mid-cycle refresh soon. Unfortunately, GM has this compact crossover covered up heavily to make sure we can't tell what's coming yet. The midsection of the vehicle remains the same as before, and we can even see the floating roof design outlined in the back by the camouflage. We imagine the majority of the changes will come up front with a new fascia including a different grille and headlight design. If it adopts the latest from the bigger Acadia, we'll be looking at a much more upright and butch-looking grille. That look descends from the full-size Sierra, though, so we'll see how much truck GMC wants to put in its small crossover. What will be most interesting of all is if GMC sticks to its guns with the wacky push-button shifter on the dash. The weird design has received mixed feedback, and this would be GMC's first big opportunity to respond. However, we expect most interior changes to be kept to a minimum, as this is only a mid-cycle refresh — GM completely redid everything for the full redesign in 2018. Additionally, we'll be interested to hear if the diesel will continue to be available as an option going forward. We'll likely see the refreshed Terrain sometime after the next Equinox is revealed. As it stands, this Terrain is probably a 2021 model year vehicle, and will be revealed at the tail end of this year, or in early 2020.
