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.

Weekly Recap: BMW rolls out ambitious plug-in hybrid electric plan

"We believe that for the United States, this is going to be very important." – Julian Arguelles Let there be no doubt, BMW is serious about electric vehicles. The German automaker said this week it will make plug-in hybrid versions of all of its core models, an aggressive move that demonstrates its commitment to electric propulsion systems. BMW did not specify which vehicles will get the plug-in systems or provide a timeline for when they will arrive. But the announcement is clearly more than blustering, and the company revealed a 3 Series plug-in prototype this week at an event in France. BMW said the 3 Series uses a version of its 2.0-liter turbocharged four-cylinder engine (240 horsepower, 300 pound feet of torque) with an electric motor sandwiched between the engine and transmission in place of the torque converter. It has an all-electric range of 22 miles. A plug-in X5 with the same powertrain was also displayed alongside the 3 Series, though the X5 has been on the auto-show circuit for more than a year, including a recent stop in Los Angeles. Those two vehicles use "eDrive," and BMW's plans represent the first widespread transfer of its technology from development of the i3 and i8 models to more mainstream products. BMW said it's developing electric powertrains so they can be deployed rapidly across its range, and they are flexible enough to be used with fuel cells in future products. Enticingly, BMW is also working on a "Power eDrive" system, which debuted in a 5 Series GT concept at the event in France. This setup has two electric motors powered by a 20-kilowatt-hour battery pack, and when teamed with a four-cylinder turbo, pump out about 670 hp. Reinforcing BMW's commitment, the company will add more than 200 jobs at its factory in Dingolfing, Germany, to support electric-vehicle development. The moves come as BMW and other automakers diversify their portfolios while fuel economy and emissions regulations are getting tighter around the world. The United States has set a 54.5-mpg CAFE requirement for the 2025 model year. BMW said the electric vehicles were developed with an eye toward the US market, its government policies and its wide-ranging commuting styles. "We believe that for the United States, this is going to be very important," spokesman Julian Arguelles said. Ben Scott, a senior analyst in London with automotive research firm IHS, said BMW's moves are expensive – but necessary – to keep pace with the market.

Suzuki recalls 2 million cars globally

Suzuki is recalling two million vehicles across the globe, including a number of Chevrolet Cruze sedans that it builds for General Motors, because the ignition switches may begin to smoke. None of the Cruzes being recalled were sold in the US, though. This recall is limited to the Japanese, European and Australian markets. In Suzuki's home market, 1,873,000 vehicles are being recalled, including the Cruze and a number kei cars built for Mazda (the Carol and AZ-Wagon), as well as the automaker's own Alto, Wagon R and Swift. Affected vehicles were built between 1998 and 2009. The remaining 133,000 vehicles include Cruzes and other Suzuki products sold in Europe and Australia. There have been no reports of injuries or accidents due to the 67 reported incidents, all of which come from the Japanese market, a Suzuki spokesperson told Automotive News. Related Video:
