Mother's Day Suggestion No. 2,506

With Mother's Day coming up, we're always looking for new gift ideas to celebrate the occasion, but hot laps around a track might not be the best suggestion for Darius Khashabi. In a video posted on YouTube, Khashabi straps his mom into the passenger seat of his C6 Corvette Z06 for some laps around Sonoma Raceway (formerly Infineon Raceway) at "60 percent" with comical results.
Now this isn't the first time Mama Khashabi has gotten seat time in her son's car around a track, as his YouTube page shows him pulling a similar stunt - with similar results - around Mazda Raceway Laguna Seca last year. Scroll down for the video, but know that the action really gets going at around the 1:40 mark.

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 Volt replacement battery cost varies wildly, up to $34,000

There's a growing hubbub in the plug-in vehicle community over what looks like some ridiculously cheap replacement batteries for the Chevrolet Volt going up for sale. GM Parts Online, for example, is selling a replacement Volt battery with an MSRP of $2,994.64 but, with an online discount, the price comes down to $2,305.88. For the 16-kWh pack in the 2012 Volt, that comes to a very low $144.11 per kilowatt hour (kWH). But is it a real deal? How can it be, when a Chevy dealer may quote you a price of up to $34,000 to replace the pack? For a 16-kWh Volt pack, $2,305.88 comes to a very low $144.11 per kWh. But is it a real deal? Battery packs in alternative propulsion vehicles are usually priced by the kWh and, historically, they've been thought to be in the range of $500-per-kWh for OEM offerings. Since automakers are understandably secretive about their costs, we still don't know what the real number is today, but we do know it varies by automaker. Tesla, for example, has said it pays less than $200-per-kWH at the cell level but, of course, a constructed pack would be more. Whatever is going on, li-ion battery prices are trending downward. So, $144.11 certainly sounds great, but what's the story here? Kevin Kelly, manager of electrification technology communications for General Motors, reminded AutoblogGreen that GM Parts Online is not the official GM parts website and that, "the costs indicated on the site are not what we would charge our dealers or owners for a replacement battery. There would be no cost to the Volt owner if their battery needs replacement or repair while the battery is under the eight year/100,000 mile limited warranty coverage provided by Chevrolet." A single price tag also can't be accurate for everyone, Kelly said. "If the customer needs to have their battery repaired beyond the warranty, the cost to them would vary depending on what needs to be replaced or repaired (i.e. number of modules, which specific internal components need replacement, etc.)." he said. "So, it's hard for us to tell you exactly what the cost would be to the customer because it varies depending on what might need to be repaired/replaced. As a result, the core charge would vary." But, is the $2,300 price even accurate for anyone? Thanks to a reader comment, we see that this similar item on New GM Parts makes it look like the lithium-ion modules that Kelly mentioned – where a lot of the expensive bits are – are not included.
