NHTSA upgrades probe into 1.7 million GM vehicles over wiper failures

WASHINGTON — The U.S. National Highway Traffic Safety Administration (NHTSA) said Tuesday it is upgrading an investigation into 1.7 million General Motors vehicles for windshield wiper failures. The auto safety agency opened the probe in November 2018 to see if GM needed to expand a 2016 recall of 2013 model year Chevrolet Equinox and GMC Terrain SUVs to cover additional vehicles. The engineering analysis probe covers 2010-2012 and 2014-2016 Equinox and Terrain vehicles. NHTSA could demand a recall after it completes the probe. NHTSA said it has reviewed 1,900 complaints and reports related to the issue in the 1.7 million vehicles. NHTSA said it has seen elevated failure rates in the 1.7 million vehicles, even though GM said the recalled vehicles have "double the warranty rate and five times the complaint rate." GM said it will "fully cooperate to support their investigation. We do not believe these windshield washer systems are defective." The wiper failures that prompted the 2016 recall were attributed to water and debris intrusion into the windshield wiper assembly ball joints, leading to excessive wear and eventual detachment of the ball joint. GM said it was installing an improved windshield wiper motor and transmission assembly and relocating a drain hole at the base of the windshield. Related Video:

Nissan Leaf, Chevy Volt have best sales month of 2015

Things are trending upwards for the two best-selling plug-in vehicles in the US. Both the Chevy Volt and the Nissan Leaf had their best sales month of 2015 in May, with the Volt selling 1,618 units and the Leaf moving 2,104. The upward swings come at an interesting time, with lots of excess first-gen Volts waiting for buyers and some buyers already ordering their second-gen Volts. So far in 2015, the Leaf has outsold the Volt 7,742 to 4,397. While 7,700 Leafs is respectable, it's nowhere near the numbers that Nissan will have to hit to reach the 50,000 annual sales that CEO Carlos Ghosn says is possible in the US. Still, the Leaf had its best sales month since December 2014 (when it sold 3,102 units) in May, but last month was still down 32.5 percent compared to May 2014. Despite the smaller overall number, May represents a big positive for Chevy, which has seen sluggish sales for the Volt for a long while now. The 1,618 Volts sold last month are only 3.9 percent lower than the 1,684 sold in May 2014 and May 2015 was the best month for Volt sales since August 2014. Perhaps salesmen are ready to make deals, what with thousands sitting around on dealer lots right now. The next-gen Volt is due this fall, and the order books (in California, at least) opened up this week. Like every month, our full wrap-up of green car sales in the US is coming soon (the VW e-Golf, for example, hit a best-ever high of 410 sales). Until then, feel free to discuss the Volt and Leaf sales figures in the Comments. Green Chevrolet Nissan Electric Hybrid ev sales hybrid sales

GMC Canyon, Chevy Colorado diesels finally heading to dealers

Customers who have been waiting to receive their diesel-powered Chevrolet Colorados and GMC Canyons should be relived to hear that GM will finally start to ship them out of the Wentzville Assembly Plant. "The highly anticipated 2016 GMC Canyon diesel has begun shipping to dealers," a company spokesperson confirmed to The Detroit News. The trucks originally had a fall launch date, but a final review forced a delay in deliveries. The 2.8-liter four-cylinder diesel in the midsize trucks produces 181 horsepower and 369 pound-feet of torque, and the company touts the engine's low emissions. The Environmental Protection Agency and California Air Resources Board even put the mill through extra scrutiny with a real world test in the wake of VW's diesel scandal, and the Duramax passed with no problems. At that time, a Chevy spokesperson told Autoblog that the models' launch was on track. The Duramax engine adds $3,730 to the price of a comparable V6 model, but they're the most fuel-efficient pickups on the market. The EPA estimates the twins at 31 miles per gallon highway, 22 mpg city, and 25 mpg combined in two-wheel drive form and 29/20/23 with four-wheel drive. Buyers likely can't wait to finally experience these pickups after reading a heap of positive reviews. The Colorado diesel recently earned Motor Trend's Truck of the Year award. We also came away impressed with it during our First Drive and liked the Canyon during our Quick Spin. Related Video:
