GM recalls 200k Hummer H3s for fire risk

An issue with fires erupting in some Hummers has prompted General Motors and the National Highway Traffic Safety Administration to issue a recall for nearly 200,000 vehicles around the world. The bulk of them are in the United States. According to the first statement (below) obtained by Autoblog from GM, the issue stems from the HVAC system in Hummer H3 models. The connector module for the blower motor has, in certain cases, overheated, melted the surrounding plastic, and started a fire. 42 such cases have been reported, including three instances of occupants citing minor burns. GM confirms that two of those three cases lead to the vehicle being destroyed in the fire, but states that no crashes or fatalities have resulted. The issue affects 196,379 examples of the 2006-10 H3 wagon and the 2009-10 H3T pickup, with 164,993 estimated to be in the United States. In order to fix the issue, dealers are being instructed to replace the relevant parts of the connector and harness. In a second, unrelated campaign, GM is also calling in 50,731 Chevy Spark and Sonic small cars – 45,785 of them in the US – due to a software glitch. In those affected vehicles fitted with the base radio and OnStar system, the audio system may not be able to switch out of turn-by-turn direction mode, causing the display to go blank and all sound to mute – including key safety warnings. In addition, the system may not switch off, draining the battery. GM states that no crashes, injuries, or fatalities have resulted from this issue, and all that dealers will need to do in this case is reflash the software.

The heat could melt the plastic surrounding the connector module, increasing the risk of a fire. Dealers will replace the affected portion of the connector and harness. GM is aware of three reported minor burns and 42 fires but no crashes or fatalities related to this condition. Including Canada, Mexico and exports, the total recall population is 196,379. ### General Motors is recalling 45,785 2014-2015 model year Chevrolet Sparks, and 2015 model year Chevrolet Sonics in the U.S.

GM may kill 6 car models as it works with UAW to tackle sales slump

The president of the United Auto Workers union said on Thursday the union is talking with General Motors about the potential threat to plants and jobs from slumping U.S. car sales. GM's response will be more trucks and SUVs, and sources say at least six slow-selling car models may be killed off. "We are talking to (GM) right now about the products that they currently have" at underused car plants such as Hamtramck in Michigan and Lordstown in Ohio, and whether they might be replaced with newer, more popular vehicles such as crossovers, Dennis Williams told reporters. "We are tracking it (and) we are addressing it," Williams added. GM has cut shifts at several U.S. plants this year as inventories of unsold cars have ballooned. Industry analysts said more jobs could be at risk as the automaker wrestles with permanently shrinking production of small and midsized sedans. GM is reviewing whether to cancel at least six passenger cars in the U.S. market after 2020, including the Chevrolet Volt hybrid, which could be replaced in 2022 with a new gasoline-electric crossover model, Reuters has learned from people familiar with the plans. Other GM cars at risk include the Buick LaCrosse, Cadillac CT6, Cadillac XTS, Chevrolet Impala and Chevrolet Sonic, sources said. Some analysts have singled out GM's Hamtramck plant in Detroit as one of the most vulnerable because of plummeting car sales. The plant, which opened in 1985, builds four slow-selling models: Buick LaCrosse, Chevrolet Impala, Cadillac CT6 and Chevrolet Volt. In the first half, it built fewer than 35,000 cars, down 32 percent from the same period in 2016, according to suppliers familiar with GM's U.S. production schedule. The typical GM assembly plant builds 200,000-300,000 vehicles a year.COMING ATTRACTIONS: TRUCKS AND SUVS GM must "create some innovative new products" to replace slow-selling sedans "or start closing plants," said Sam Fiorani, vice president of AutoForecast Solutions. The auto maker already has begun to shift future production plans from cars to trucks, according to Morgan Stanley auto analyst John Murphy. He estimates that fewer than 10 percent of the new vehicle models that GM will introduce over the next four years will be passenger cars, with the rest divided among trucks, SUVs and crossovers. GM plans to add production of the new Cadillac XT4 crossover next year to its Malibu sedan plant in Fairfax, Kansas.

Stop-start standard in four-cylinder 2015 Chevrolet Impala

Chevrolet has announced that it will include stop-start technology as standard in the entry level 2015 Impala. The result is a nearly five-percent improvement in city fuel economy, also known as one mile per gallon, up to 25 mpg, combined. The 3.6-liter V-6 Impala will not feature stop-start. The 2015 Impala comes equipped with Chevrolet's 2.5-liter Ecotec four-cylinder engine, which will also offer 22 mpg in the city, and 31 on the highway. The 3.6-liter V-6 Impala will not feature stop-start and the mild-hybrid eAssist model from the 2014 MY, which got 29/25/35 combined/city/highway mpg, has been discontinued. Chevrolet spokesman Chad Lyons told Green Car Reports that not even one percent of the 2014 Impalas purchased were the Eco model. So Chevy is trying something different. With a seamless driving experience in mind, the new Impala's stop-start tech features software that governs under what conditions the feature will activate. The engine won't shut off if the car has not reached a speed of six miles per hour, so the start-stop won't be cycling during traffic jams. It can also fire the starter even if the engine has not come to a full stop, which quickens reaction time, particularly in instances of what Chevrolet calls "change-of-mind events." The stop-start function uses information about cabin temperature and humidity as well as battery charge to help determine whether or not to shut off the engine. The 2015 Impala has been engineered to reduce NVH, which will also help create a smoother stop-start experience for occupants, Chevy says. Motor mounts have been updated, and a burlier starter motor will help restart the engine after a stop. The Impala follows the 2014 Malibu as Chevrolet's second vehicle to feature stop-start tech. The four-cylinder model currently makes up over 30 percent of Impala sales. The 2015 Impala will be available beginning this summer, with a base MSRP of $27,735 (including destination charges). And while one MPG isn't a huge difference, neither is the price increase of just $50 for a bit of eco-minded innovation. Read on for more details in the press release below.
