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 issues four new recalls, 2.4 million cars affected

General Motors has announced another set of recalls, covering some 2.42 million cars in the United States. For those keeping track, The General has now recalled over 15 million cars worldwide this year due to various issues.
Here's the breakdown for this most recent set of recalls:
1,339,355 - Buick Enclave, Chevrolet Traverse, GMC Acadia models from the 2009 to 2014 model years; Saturn Outlook models from the 2009 to 2010 model years

Junkyard Gem: 1962 Buick LeSabre 2-Door Sport Coupe

American car shoppers looking for a full-sized hardtop coupe in 1962 couldn't go wrong with the offerings from The General. Chevrolet would sell you a snazzy new Bel Air sport coupe for just $2,561 (about $23,800 today), but those Joneses next door wouldn't have felt properly shamed if you put a new proletariat-grade Chevy in your driveway. No, to really stand tall during the era of Alfred Sloan's Ladder of Success, you had to go higher up on the GM food chain. For the B-platform full-sized cars of 1962, that meant the Pontiac Catalina/Bonneville beat the Chevy, the Oldsmobile 88 was the next step up the ladder, and at the very top was the Buick: the hot-rod Invicta and its swanky LeSabre sibling. To go beyond that, you had to move up to a C-platform Buick Electra or Cadillac. Today's Junkyard Gem is a once-luxurious '62 LeSabre, now much-faded in a northeastern Colorado boneyard. The reason GM shoppers got so bent out of shape about the "Chevymobile" episodes of the late 1970s, in which some GM cars received engines made by "lesser" GM divisions, was that each division had its own family of V8 engines during the 1950s and 1960s and they weren't supposed to be mingled. The '62 LeSabre got a 401-cubic-inch (6.5-liter) Nailhead engine (so called because the valves were unusually small), rated at 265, 280, or 325 (depending on what kind of compression ratio and carburetion you wanted). That's not crazy horses for a big-displacement, two-ton luxury coupe of its era, but the small valves allowed for combustion chambers optimized for one thing: low-rpm torque. This 401 has the two-barrel carburetor, so it made either 412 or 425 pound-feet of torque. That's just a bit less than the mighty Cadillac's engine that year, and definitely sufficient to get this car moving very quickly. You had to pay a fat premium on the Chevrolet, Pontiac, and Oldsmobile B-bodies to get an automatic transmission (a three-speed column-shift manual was base equipment in those cars), but a Turbine-Drive (formerly known as the Dyna-Flow) automatic was standard issue on the 1962 LeSabre. This was an interesting transmission design that traced its origins back to the 1942 M18 Hellcat Tank Destroyer and used torque-converter multiplication to provide a CVT-like experience with no perceptible shifts (the driver could select a separate low gearset manually, so the shifter looks just like the one on the true two-speed Powerglide transmission).
