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.

Question of the Day: Coolest factory-supercharged car?

Last week, we discussed possible engine-swap recipients for the plentiful-in-every-junkyard Eaton-supercharged GM 3800 V6 engine. The Buicks, Oldsmobiles, and Pontiacs that came with that engine from the factory were reasonably cool, of course, but when you look at all the production cars that have been available with supercharging over the decades you can find some pretty amazing stuff. My personal favorite has to be the Paxton-blown Studebaker Larks of the early 1960s, partly because the Lark was just about the stodgiest-looking, sleepiest little sedan available in America, possibly the most ridiculous recipient of a howling force-fed V8 imaginable, and partly because of the name of the optional supercharged 289-cubic-inch V8 you could get in the Lark: Jet-Thrust! What do you say is the coolest factory-supercharged car of all time? Related Video: Auto News Buick Automotive History Performance Classics supercharger questions

GM seeks to exempt Buick Envision from U.S. auto tariffs

General Motors is seeking an exemption to a 25 percent U.S. tariff on its Chinese-made Buick Envision sport utility, the automaker said on Thursday, in a move to prevent the key model in the brand's U.S. lineup from becoming a victim of the U.S.-China trade war. The midsize SUV, priced starting at about $35,000, has become a target for critics of Chinese-made goods, including leaders of the United Auto Workers union and members in key political swing states such as Michigan and Ohio. The Envision, assembled only in China, last year accounted for about 19 percent of Buick brand sales in the United States. GM said in a statement that it filed the request on July 30 with the U.S. Trade Representative. An official notice was posted on Thursday on the regulations.gov website, which is tracking requests for exclusions from the so-called Section 301 tariff on certain imported goods from China. GM, the largest U.S. automaker, argued in its request that Envision sales in China and the United States would generate funds "to invest in our U.S. manufacturing facilities and to develop the next generation of automotive technology in the United States." GM said the "vast majority" of Envisions, about 200,000 a year, are sold in China. About 41,000 were sold last year in the United States. Because of the lower U.S. sales volume, "assembly in our home market is not an option" for the Envision, which competes with such midsize crossover vehicles as the Jeep Grand Cherokee and the Cadillac XT5. GM has taken other steps to soften the blow of tariffs, which hit just as the automaker had lowered the price of the Envision to make it more competitive. Ahead of the July 6 start for higher import tariffs, GM shipped in a six-month supply of Envisions at the much lower 2.5 percent tariff rate. Envision sales from April through June plunged to just 7,000 vehicles, while inventories climbed to more than 13,000 vehicles at the end of June. At the current sales rate, the Envision supply should be enough to keep many dealers stocked through the end of the year. GM had lowered prices by as much as $2,500 on the 2019 models, which it started shipping in late April. That means Buick's 2,000 U.S. dealers should have lower-priced Envisions to sell well into the fall. "The previous price point was too high" on the 2018 Envision, said Casey Clark, sales manager at Serra Buick GMC Cadillac in Washington, Michigan, in an interview.
