GM recalls trucks and SUVs for brake pedal problem

The Basics: General Motors will recall over 473,000 North American examples of the 2015-2016 Chevrolet Silverado HD, GMC Sierra HD, and police pursuit versions of the Chevy Tahoe. These include 426,573 vehicles in the US and 46,837 in Canada, according to Reuters. The Problem: The brake pivot nut can loosen over time, which can render the pedal inoperative. This would be a danger to drivers trying to stop the vehicles. In some cases, the "Service Engine Soon" light might come on. Injuries/Deaths: None reported. The Fix: Dealers will inspect the pivot bolt, and if necessary they will apply adhesive to it and reinstall the part with increased torque. If You Own One: "We expect to start customer notifications shortly," GM spokesperson Tom Wilkinson told Autoblog.

If the brake pedal becomes loose or inoperative, it could interfere with the accelerator pedal, and/or the driver may be unable to safely stop the vehicle through application of the brake pedal, potentially affecting stopping distances and increasing the risk of a crash causing injury and/or damage to property. Correction: Dealers will inspect the pivot bolt installation to determine whether the vehicle has already received the production remedy. If not, the dealer will add adhesive to the nut, and reinstall the nut at an increased torque.

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.

Brief website update hints 2016 Chevy Volt will get 43 mpg, 106 MPGe

Customers in California can already order the 2016 Chevrolet Volt and be the first to own the new, range-extended EV in August. It appears there's now a possibility that buyers of the updated model might get slightly better economy than Chevy's initial announcement from the 2015 Detroit Auto Show in January, too. According to the eagle-eyed folks at GM-Volt.com, Chevy has been subtly tweaking the spec page for the 2016 Volt. It briefly showed the model getting 43 miles per gallon combined fuel economy and 106 mpge, rather than the originally released figures of 41 mpg and 102 mpge. Shortly afterward, the internal-combustion mileage returned to 41 mpg, but 106 mpge remained. A GM spokesperson told Hybrid Cars the changes happened by mistake. "We have not finalized numbers yet. We expect to announce in July." The economy isn't the only statistic to see an adjustment, though. The total range was reportedly briefly shown as 420 miles, and then returned to a 430-mile rating, according to Hybrid Cars. The Volt's output has also been slightly tweaked from the original figures. It's now displayed as 150 horsepower and 293 pound-feet of torque, versus the preliminary numbers of 149 hp and 294 lb-ft. These tiny changes likely have a negligible impact on real-world driving, but they suggest that Chevy's team is still working to squeeze as much as possible from the latest Volt's powertrain. If the final figures are coming in July, then the engineers still have just a few weeks to improve the ratings even more.
