GM execs fired over fraudulent India emissions testing

General Motors hadn't had a recall in India since 1995. That changed when it was discovered that certain employees were playing tricks with local emissions testing in order to ensure passing grades for engines. More than ten GM Powertrain employees in India and the US have been let go over the ensuing emissions flap, including Sam Winegarden, VP of global engine engineering, a man who has been with the company since 1969, leading development of some marquee powerplants.
According to Automotive News, an internal investigation revealed that employees "violated testing procedures," sometimes swapping specially prepared low-emissions engines during testing regimes for the Chevrolet Tavera SUV equipped with the 2.0-liter and 2.5-liter engines. Employees were also manipulating weights in order to get vehicles placed into different emissions categories. The discovery has led to GM recall the 114,000 Taveras produced over an eight-year period and halting their production and sale.
The Economic Times of India reports that the issue is due to "a faulty component." GM has developed a solution to the issue, and once it is validated in testing and approved by the Indian authorities, the recalled vehicles will be fixed at dealers and production will resume.

GM trucks get hybrid versions, but you'll probably never see one

A few years ago, General Motors sold hybrid versions of its Chevy Silverado and GMC Sierra pickups. They weren't very good, using GM's old two-mode hybrid system that resulted in only negligible fuel economy gains. But GM's trying again, launching eAssist models of the 2016 Silverado and Sierra that are said to offer 2-mpg improvements in city, highway, and combined fuel economy ratings. Problem is, you probably won't be able to get one. Only 700 eAssist trucks will be made for the 2016 model year – 500 Silverados and 200 Sierras. When you consider that GM moved 824,683 examples of its light-duty pickups in 2015, this small run represents 0.08-percent of all Silverado/Sierra production, and GM says it "will monitor the market closely ... and adjust as appropriate moving forward." But that's not the only limitation. The eAssist trucks will only be sold through California dealers. For the Silverado, eAssist can only be optioned on the 1500 Crew Cab 1LT 2WD model, and for the Sierra, the fuel-saving technology is solely available on the 1500 SLT Crew Cab 2WD model with the SLT Premium Plus package. Granted, in terms of the Sierra, that means you get niceties like LED headlights and taillights, Apple CarPlay and Android Auto, Bose premium audio, heated seats and steering wheel, lane keep assist, and more. In the trucks, eAssist combines a small electric motor and 0.45-kWh battery pack with the pickups' 5.3-liter V8. GM estimates total output of 355 horsepower and 383 pound-feet of torque – no more horsepower than the non-eAssist trucks, but three more pound-feet of torque. GM says the eAssist trucks can tow up to 9,400 pounds, and the battery only adds 100 pounds to the trucks' weight. The electric motor provides 13 hp and 44 lb-ft of torque for a boost of acceleration off the line, or during passing. It also allows the engine to run in four-cylinder mode for longer periods of time. eAssist uses regenerative braking to help power onboard electrical systems, and adds start/stop to the powertrain. Finally, the so-equipped trucks have a six-percent improvement in aerodynamics, thanks to a soft tonneau cover and active grille shutters in the front fascia. Great news is, the eAssist option is relatively inexpensive, only costing $500. But good luck getting your hands on one.

GM tells owners not to use SUV wipers due to fire risk

General Motors is recalling 31,685 examples of the 2016 Buick Enclave, Chevrolet Traverse, and GMC Acadia because a short circuit in the windshield wiper motor can potentially lead to a fire. Due to the danger, the company is asking owners not to use the wipers until the problem is fixed, according to The Detroit Free Press citing the Associated Press. A manufacturing defect in the wiper motor cover means that the electrical terminals can come into contact and cause a short. The part could "melt, smoke, or catch fire," according to a statement from GM. The company will get them fixed immediately, and dealers will replace the cover. If there's bad weather at the time the owner specifies to get the recall work completed, the automaker will come pick up the crossovers. Depending on parts availability, the automaker will supply a rental car for customers, as well. The issue was discovered at the factory. According to the company's statement, only 6,405 actually made it to customers, and they were notified immediately by overnight letter. The rest were in dealer stock. The affected crossovers carry build dates between August 18, 2015 and September 24, 2015. Of those, there are 29,295 in the US and 1,073 in Canada. GM Statement: General Motors has told the National Highway Traffic Safety Administration that it will recall approximately 29,295 2016 model year Chevrolet Traverse, Buick Enclave and GMC Acadia SUVs in the U.S. because the front windshield wiper motor may overheat when in use because of a manufacturing defect. In some cases, the front windshield wiper motor cover may melt, smoke or catch fire. The approximately 6,405 customers who have taken delivery of these vehicles were notified by overnight letter and are urged to contact a GM dealer as soon as possible to arrange a service appointment. These customers should not use the front windshield wipers until they have been repaired. If weather conditions prevent driving the vehicle without using the windshield wipers, GM will arrange to pick up the vehicle for servicing. If repair parts are unavailable, GM will provide a rental car at no cost until parts become available. The total population, including Canada, Mexico and exports, is approximately 31,685. About 25,280 of these vehicles are in dealer stock and will not be sold until repairs are made.
