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.

Detroit 3 to implement delayed unified towing standards for 2015

Car buyers have a responsibility to be well-informed consumers. That's not always a very simple task, but some guidelines are self-evident. If you live in a very snowy climate, you generally know a Ford Mustang or Chevrolet Camaro might not be as viable a vehicle choice as an all-wheel drive Explorer or Traverse, for example. If you want a fuel-efficient car, it's generally a good idea to know the difference between a diesel and a hybrid. But what if it's kind of tough to be an informed consumer? What if the information you need is more difficult to come by, or worse, based on different standards for each vehicle? Well, in that case, you might be a truck shopper. For years, customers of light-duty pickups have had to suffer through different ratings of towing capacities for each brand. For 2015 model year trucks, though, that will no longer be a problem. According to Automotive News, General Motors, Ford and Chrysler Group have announced that starting with next year's models, a common standard will be used to measure towing capacity. The Detroit Three will join Toyota, which adopted the Society of Automotive Engineers' so-called SAE J2807 standards way back in 2011. The standard was originally supposed to be in place for MY2013, but concerns that it would lower the overall stated capacity for trucks led Detroit automakers to pass. Ford originally passed, claiming it'd wait until its new F-150 was launched to adopt the new standards, leading GM and Ram to follow suit. Nissan, meanwhile, has said it will adopt the new standards as its vehicles are updated, meaning the company's next-generation Titan should adhere to the same tow ratings as its competitors. While the adoption of SAE J2807 will be helpful for light-duty customers, those interested in bigger trucks will still be left with differing standards. There is no sign of the new tow standards being adopted for the heavy-duty market.

Mustang retakes monthly pony car sales crown from Camaro

Going back to their origins in the Swinging '60s, the Ford Mustang and Chevrolet Camaro have been fierce rivals for fans' hearts and dollars. Historically, the Ford often led in volume, but Chevy took the muscle car top spot in 2009 upon the Camaro's rebirth. However, with the launch of the latest Blue Oval pony car, the tide is turning back in Ford's favor. November was the first full month of sales for the new 2015 Mustang, and according to TheDetroitBureau.com, the model did spectacularly well. The Blue Oval shifted 8,728 of them, up 62 percent from same month last year, with the automaker proclaiming it the model's best November sales since 2006. Conversely, 4,385 units of the Camaro were delivered, down 13.5 percent year-over-year, meaning its sales were roughly half that of the new-generation Mustang. Ford is understandably happy with the results, and product development director Raj Nair even hinted to TDB that another version of the Mustang might be unveiled at January's North American International Auto Show. Rumor has it that the model will be the even more potent Shelby Mustang GT350R. Despite the Mustang's November success, the Camaro outsells it year to day. So far in 2014, Ford has sold 73,124 Mustangs versus 79,669 examples of the Camaro. With December offering the last chance for an overtake, the Bowtie may yet remain king for this year's sales crown. A new Camaro is peeking over the horizon, as well. It's reportedly moving to the Alpha platform used by the Cadillac ATS, and production could start in late 2015. Prototypes are already testing at the Nurburgring, and camouflaged examples have been spotted weirdly being compared to its '80s forefather.
