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: NEDC's NOx problems, autonomous Chevy Volts

The International Council on Clean Transportation (ICCT) found a significant difference in NOx emissions in Euro 6 diesel cars in NEDC and WLTC testing. While 88 percent of the cars tested met emissions standards for NEDC, NOx emissions averaged five times higher under WLTC, with only 27 percent of vehicles under the limit. WLTC is considered to be a more realistic driving cycle, using hot starts and factoring a higher top speed as well as harder and more frequent accelerations than the NEDC.

Employees will be able to use a carsharing app to reserve a car, which will then drive itself to the set destination. The project will allow GM to collect important data and experience to help the company more quickly develop autonomous driving technology.

The lithium-ion batteries used to power the EV were recycled from other Renault EVs. With the electric Trafic, Carwatt – a company that converts vehicles to use electric power – aims to demonstrate the "circular economy" of batteries, which can provide more value through a longer lifecycle. Read more in the press release below. Carwatt presents a unique automotive application for second-life batteries from electric vehicles. On the sidelines of the COP21 summit, in the Solutions Gallery running from 2 to 9 December 2015 in Le Bourget near Paris, Carwatt and its partners —Renault, Paris City Council, BPI France, the Ales Ecole des Mines Engineering School, and the Bobigny Business Campus — are showing a very special electric Renault Trafic. This prototype vehicle, the only one of kind in the world, is powered by second-life lithium-ion batteries recycled from Renault electric cars. Circular economy at work with electric vehicles When, over time, the batteries of a Renault electric vehicle fall the performance threshold specified for their initial automotive power duty (around 75% of initial capacity), they can still provide valuable service in "second-life" applications before end-of-life disposal at a recycling centre. Experiments are already under way on power storage applications, for example.

How Chevy Silverado, GMC Sierra will take on the Ford F-150 profit machine

FORT WAYNE, Ind. — When General Motors engineers were developing the 2019 Chevrolet Silverado and GMC Sierra pickup trucks, some of them joined public tours of Ford's Dearborn, Mich., factory to watch aluminum-bodied F-Series trucks go down the assembly line. The redesign of the Ford F-Series trucks, launched in 2014, set a new standard for fuel economy and lightweight vehicle construction. But armed with stopwatches and trained eyes, the GM engineers believed they saw problems. "They had a real hard time getting those doors to fit," Tim Herrick, the executive chief engineer for GM truck programs, told Reuters. His team did more intelligence gathering. They bought and tore apart Ford F-Series doors sold as repair parts. Their conclusion: GM could cut weight in its trucks for a lower cost using doors made of a combination of aluminum and high-strength steel that could be thinner than standard steel, shaving off kilograms in the process. These pounds-and-pennies decisions will have major implications in the highest-stakes game going in Detroit: dominance in the world's most profitable vehicle market, the gasoline-fueled large pickup segment. What's more, GM is banking on strong sales of overhauled 2019 Silverados and GMC Sierras to fund its push into automated and electric vehicles — a business many investors see as the auto industry's long-term future. The risks are high given the hits automakers have taken from U.S. President Donald Trump's trade policies. Rising aluminum prices spurred by Trump's tariffs are driving up costs on the Ford's F-Series, while rising steel and aluminum prices likewise drag on GM results. GM also has a significant risk should the United States, Mexico and Canada fail to agree on a new NAFTA trade deal, given GM trucks built at its Silao, Mexico, factory could face a 25 percent tariff if NAFTA collapses. Major profit per truck Interviews with GM executives and a tour at its factory here in northwest Indiana provide a detailed look inside GM's plan for the most important vehicles in its global lineup. These big pickups are everything Tesla's Model 3 or Chevy's Bolt electric car is not. The mostly steel body is bolted to the truck's steel frame, rather than the one-piece body and frame electric vehicles. The majority of trucks will have a V-8 gasoline engine powering the rear wheels — like the classic GM cars of the 1950s. Some Silverados will have new four-cylinder engines, but there is no electric or hybrid offering as of now.
