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.

GM applies for LT5, LTX trademarks... are new small block variants coming?

Recently discovered General Motors trademark applications for LT4, LT5, LT88 and LTX have observers wondering what kind of high-performance offerings could be on their way. A new LT4 would mark a return of the engine designation first used on the Corvette Grand Sport, SLP Pontiac Firehawk and SLP Chevrolet Camaro SS from 1996 and 1997. Supposition at Corvette Forum - which provided advance intel on the C7 like these leaked images - believes a new LT4 could go into the high-performance trim of the next-gen, 2015 Camaro that would be more powerful than the 580-horsepower Camaro ZL1.
Seeing an LT5 again would also be déjà vu - in its former life it was a 5.7-liter V8 for the C4 Corvette ZR-1 from 1990-1994 designed by Lotus, producing from 370 hp to 405 hp. A mix of rumor and hope is that the new LT5 will be a supercharged evolution of the 6.2-liter LT1 (pictured) placed in the new C7 Corvette, and that it will go into the C7 version of the ZR1 pumping out something like 700 hp.
The LTX trademark is, as with that last letter, a complete mystery. If the "X" isn't a generic way to denote the whole LT family, it's wondered if it LTX could refer to a crate motor offering like the LSX.

Nissan Leaf sets another monthly sales record, Chevy Volt remains steady

Here we go again. Another month in the books and another month of record sales by the Nissan Leaf in the US. For October, the world's best-selling pure EV sold 2,589 units, which is 29.3 percent more than October 2013. That makes it 20 times in a row that Nissan can say that last month sales were better than the same month a year before. All told, Nissan has sold 24,411 Leafs in the US this year, a new record, reflecting an overall Leaf sales rate that is up 35 percent, year-to-date. Nissan isn't stopping, either. A new TV ad, one that, "encourages consumers to kick gas" by saving money on fuel will start airing today in major markets, according to Toby Perry, director of Nissan's EV marketing. You can watch it below. As for the Chevy Volt, things remained steady last month in the face of a new model that's coming in the second half of 2015. Chevy sold 1,439 Volts last month, which is about the same as September (1,394) but down 28.8 percent from the October 2013 despite GM having its best overall US October sales this year since 2007. So far, 2014 Volt year-to-date sales are down 14.9 percent through the end of October compared to 2013. And that wraps up the flash report on monthly sales for these two long-standing plug-in vehicles in the US market. As always, we'll have our in-depth write-up of US green car sales available soon.
