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.

Recharge Wrap-up: Detroit Electric teaser video, Nissan Leaf is Good Housekeeping "Tried and Tested"

Detroit Electric has a new teaser video and has updated its brand in preparation of the introduction of the SP:01. The refreshed logo uses a blue and white color palette, and the company has also given its website a new look. The teaser video, which gives a sneak peek at the exterior of the SP:01, shows the car taking form in the midst of an electrical storm. Watch the video or learn more in the press release below. Abengoa is celebrating the grand opening of a commercial scale cellulosic ethanol plant in Hugoton, KS. When running at full scale, the refinery will produce up to 25 million gallons of ethanol a year. The plant will also generate enough electricity to power itself and put some back into the grid. Energy Secretary Ernest Moniz was on hand for the dedication, saying, "Every gallon of cellulosic ethanol produced and used to fuel our vehicles reduces the impact of harmful greenhouse gas emissions by greater than 60 percent as compared to conventional gasoline."

The magazine's research institute evaluated the EV based on track and road driving, ergonomics and convenience features. Good Housekeeping made note of the car's "impressive" range, but according to Nissan's Fred Diaz, "the real beauty of the Nissan Leaf is that it's roomy and, best of all, fun to drive."

It uses things like grains leftover from brewing Budweiser, food waste from a baseball stadium and sewage sludge to produce the gas through anaerobic digestion. The compressed gas can then be used to power cars like Chevrolet's Bi-fuel Impala, which goes on sale later this year. Chevrolet likens the situation to the Delorean time machine in the Back To The Future movie series, which uses garbage to fuel its fusion generator.

Weekly Recap: Racing legend Jim Hall explains Chevy's futuristic Chaparral concept

"I said our cars are built to be winners." – Jim Hall Racing legend Jim Hall never thought he'd be a video game consultant, but when Chevrolet asked for his advice to create a futuristic Chaparral for the Vision Gran Turismo series, he was eager to help. He reviewed early sketches and suggested some changes that made it onto the concept, including the addition of a camera that's mounted onto a mast over the cabin to aid the driver. The Chevy Chaparral 2X Vision Gran Turismo concept was revealed this week at the Los Angeles Auto Show and will be part of a downloadable update for PlayStation 3's Gran Turismo 6 in December. Theoretically, at least, it uses a laser-beam propulsion system and an air-powered generator to produce 900 horsepower in the video game. It's capable of sprinting to 60 miles per hour in 1.5 seconds en route to a top speed of 240 mph. Those gaudy performance specs – even in the virtual world – came at Hall's urging. "I said our cars are built to be winners," Hall told Autoblog on the floor of the Los Angeles show. The 79-year-old drove Lotus racecars in Formula One before launching the successful Chaparral Cars in the 1960s. Like his innovative Can-Am racers, the Vision Gran Turismo project has an eye toward the future. It also introduces the iconic Chaparral name to a new generation of fans, and hopefully, Hall says, gets them excited about engineering and design. "It emulates what we did in the '60s," he said. And what they did back then still resonates. Chaparral Racing and Chevy partnered more than 45 years ago for development work on the composite monocoque chassis, lightweight alloy powertrains, automatic gearboxes and active aerodynamics. "He [Hall] walked right back into this and was able to apply thinkings and learnings," said Clay Dean, General Motors executive director of advanced design. The Chevy Chaparral 2X Vision Gran Turismo concept was created at GM's North Hollywood advanced design studio, and it will be on display at the show through November.
