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:

GM will recall 3.5 million pickups and SUVs to fix brake issue

WASHINGTON — General Motors Co is recalling 3.46 million U.S. pickup trucks and SUVs to address a vacuum pump issue that could make braking more difficult and increase the risk of a crash. The recall, which covers 2014-2018 model year vehicles, including some Cadillac Escalade, Chevrolet Silverado, Chevrolet Tahoe, GMC Sierra, Chevrolet Suburban and GMC Yukon vehicles, was triggered because the amount of vacuum created by the vacuum pump may decrease over time, GM told the National Highway Traffic Safety Administration (NHTSA) in documents posted Wednesday. NHTSA opened a preliminary investigation into the issue in November 2018, and said it had reports of 9 crashes and two injuries related to the issue. It provided GM in July with additional field reports that prompted the automaker to open an investigation. The company did not immediately say on Wednesday how many injuries or crashes are linked to the issue but said it could impact braking in "rare circumstances." GM said dealers will reprogram the Electronic Brake Control Module with a new calibration that will improve how the system utilizes the hydraulic brake boost assist function when vacuum assist is depleted. GM said the vacuum assist pump, which is lubricated with engine oil that flows into the pump through a filter screen, can in some cases lose effectiveness over time, as debris such as oil sludge can accumulate on the filter screen. GM told NHTSA that prior model years used a different brake assist system design, and vehicles manufactured after 2018 were not equipped with the affected pump design. Recalls Chevrolet GM GMC

2019 GMC Sierra 1500 spied in base trim level

When the 2019 GMC Sierra 1500 half-ton pickup was revealed, it was shown in the ultra-deluxe Denali trim with its carbon fiber bed and trick tailgate. And thanks to spy shots, we've been able to see the more modest SLE a few months ago. Now we get to see it in the most plain work truck iteration thanks to the above photos. This Sierra doesn't appear to have any trim designation. The SLE we saw had a badge in the lower left of the tailgate, but none appear on this except "Sierra." This fits with the current trim scheme for the Sierra, which calls the basic one simply by its model name. In addition to less badging, this Sierra ditches most of the chrome found on other trim levels. The grille insert is plain black plastic, as are the fender vents, door handles and window trim. There aren't engine badges, either. Currently the only engines announced for the Sierra are the gasoline 5.3-liter and 6.2-liter V8s and the diesel 3.0-liter six-cylinder. We would assume from the basic nature of this truck that it has the 5.3-liter V8. Nothing has been announced about a gasoline V6 for the new generation of Sierra and Silverado pickup trucks, despite a 4.3-liter V6 still being available on the 2018 model. Also, since this is a base Sierra, the bed is all steel and the tailgate is one big panel. Pricing still hasn't been revealed for the Sierra. But this and the other Sierra trims will go on sale in the fall, with pricing likely announced sometime in-between. Related Video: This content is hosted by a third party.
