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.

Chevy recalls 73k Cobalts for side airbag non-deployment

Chevrolet is recalling 73,424 examples of the 2010 Cobalt in the US and Canada because the driver's side curtain airbag might not deploy in a crash. These vehicles carry build dates between January 4 and June 23, 2010, and, specifically, 59,474 of them are in the US. "GM is aware of one crash with one injury that may be related to this condition," the company said in a statement. The problem occurs because of improper routing of the side-impact sensor wiring harness in the driver's door, and there can be a short circuit causing the curtain airbag not to deploy. The campaign to fix the issue will begin on August 26. Dealers will inspect the vehicles and will repair the issue on any affected examples.

Dealers will inspect all suspect vehicles and any found with the condition will be repaired free of charge to the customer. GM is aware of one crash with one injury that may be related to this condition. Including vehicles sold in Canada, the total recall population is 73,424. RECALL Subject : Improperly Routed Side Impact Wire Harness Report Receipt Date: AUG 10, 2015 NHTSA Campaign Number: 15V500000 Component(s): AIR BAGS Potential Number of Units Affected: 59,474 All Products Associated with this Recall Vehicle Make Model Model Year(s) CHEVROLET COBALT 2010 Details Manufacturer: General Motors LLC SUMMARY: General Motors LLC (GM) is recalling certain model year 2010 Chevrolet Cobalt vehicles manufactured January 4, 2010, to June 23, 2010. The affected vehicles may be equipped with an improperly routed Side-Impact Sensor (SIS) wiring harness in the driver side front door. The misrouted wiring harness could cause an electrical short that disables the driver side curtain air bag. CONSEQUENCE: A disabled driver side roof-rail air bag will not deploy in the event of a crash necessitating deployment of that air bag, increasing the risk of injury to the driver. REMEDY: GM will notify owners, and dealers will inspect the sensor's wiring in the driver's door and make repairs as necessary, free of charge. The recall is expected to begin August 26, 2015. Owners may contact Chevrolet customer service at 1-800-222-1020. GM's number for this recall is 15075.

Next-gen Chevy Silverado and GMC Sierra may use carbon fiber

It's been generally accepted that the next generation of full-size GM trucks will use some sort of strong, lightweight material for the beds while retaining steel for the cab. While aluminum seems like the most obvious choice, according to Automotive News, the Chevy Silverado and GMC Sierra will incorporate both aluminum and carbon fiber in their beds. The publication cites sources from within GM, though it seems the introduction of this comparatively exotic material mix is still a few years off. While carbon fiber is both stronger and lighter than steel and aluminum, it takes significantly more time and money to produce, essentially relegating the material to small-volume cars. The main benefit for trucks is the resulting reduction in weight to improve fuel economy without sacrificing the tough, rugged capabilities truck buyers expect. The Ford F-150 made the switch to aluminum for the 2015 model year and it's proved highly successful. It seemed like it was only a matter of time before the competition followed suit. Automotive News says that the next-gen trucks will launch with aluminum beds and that it will take a couple of years before we'll see any carbon fiber incorporated into the design. Even then, only look for the composite material on higher-trim models, with a trickle down to lower-spec trucks possible further in the future. In 2011, GM announced it was working with Japan-based Teijin Limited on a carbon fiber reinforced thermoplastic. There's a good chance that material's introduction will be on trucks.
