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.

GM Ultium tech can scavenge heat from everywhere, even you

GM likes to give us tidbits about its Ultium platform from time to time, and today it’s telling us about the platformÂ’s ability to capture waste heat from the propulsion system. In addition to capturing from the propulsion system, it can also capture humidity from both inside and outside the vehicle and even from passengersÂ’ body heat. Yes, you, your family and/or your friends are a usable heat source as far as GM EVs are concerned. It then deploys the heat in an advantageous way. If at this point, youÂ’re screaming, "Heat pump!" youÂ’d be right. WeÂ’re talking about an elaborate heat pump system that GM is using for its Ultium-based vehicles. Every Ultium-based GM vehicle gets this system that is covered by 11 patents and four publications. The waste heat it collects is used in a number of ways, but its primary use is to heat the cabin quickly and efficiently. GM claims it can heat the cabin of its Ultium-based vehicles quicker than vehicles with traditional internal combustion engines. Plus, when put to use, GM claims that using the heat pump provides its EVs with up to 10% more range than theyÂ’d have without. Beyond heating the cabin, the heat pump is capable of putting waste heat to use by preheating the battery prior to charging so that you can charge quicker. The system can even cool the propulsion system in preparation for Watts to Freedom (WTF) launch control starts. GM says this was vital in helping the Hummer EV achieve its bonkers 0-60 mph time of about 3 seconds. “Having a ground-up EV architecture gives us the freedom to build in standard features like UltiumÂ’s energy recovery capabilities,” said Doug Parks, GM executive VP of global product development, purchasing and supply chain. “This helps us squeeze more efficiency, performance and overall customer benefit out of our EVs.” GM says itÂ’s been developing heat pump technology since the EV1 and its heat pump. This is the modern evolution of that technology, and GM says itÂ’s going to be implemented in every Ultium-based vehicle as a standard feature.

2022 GMC Sierra Denali Ultimate vs. 2022 Ram 1500 Limited Longhorn vs. Ford F-150 Limited | Luxury truck interior face-off

GMC's new uber-expensive 2022 Sierra Denali Ultimate is the latest luxury truck to nudge toward six-figure territory. With demand for upmarket half-tons surging, GMC's otherwise-solid pickup found itself in desperate need of an interior remodel. For 2022, we're getting just that, and it appears ready to take the fight to the segment's best, including the 2022 Ram 1500 Limited and 2022 Ford F-150 Limited. Here's the new Denali Ultimate interior in all of its full-grain, open-pore glory. 2022 GMC Sierra 1500 Denali Ultimate vs. 2021 GMC Denali  Not only did the material quality and styling both improve greatly, but the new truck also gets a completely different shifter setup (truck buyers don't like column shifters anymore, apparently). It would actually be difficult to overstate the quality of the upgrade here; the photos really speak for themselves. It's also worth noting that in addition to looking significantly more upscale than the model it's succeeding, the new Denali interior also differs a bit more from its Chevy counterpart than its predecessor did. Here's the new Silverado High Country for reference: While some elements do carry over, the entire dash design is different, down to the positioning of the heating and cooling vents. While the main HVAC controls are essentially carried over, note that they're pretty much the only ones. Even the horizontal bar of switches running along the center stack is positioned differently between the two. Yep. This is a pretty big upgrade over the 2021 cabin, and clearly the range-topper in GM's truck hierarchy. But what of the competition? 2022 GMC Sierra 1500 Denali Ultimate vs. 2022 Ram Limited Longhorn Southfork This one's tough. We're going to have to spend time in them back to back, but the Ram Limited, with its various anniversary editions and other special permutations, is certainly the interior to beat. To our eyes, the Sierra's more horizontal layout is a bit more modern and perhaps luxurious-looking than the more upright cabin treatment of the Ram, but it's tough to say for certain from photos. Both the Denali Ultimate and Ram Limited carry their upscale feel into their back benches too, which is something we can't say quite as confidently about our next contestant.  2022 GMC Sierra 1500 Denali Ultimate vs. 2021 Ford F-150 Limited The Ford F-150 Limited holds its own, but it's probably the least photogenic of the models we've looked at here, at least apart from the outgoing Denali.
