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:

Weekly Recap: Lincoln Continental serves up the style, Cadillac CT6 delivers the substance in New York

Lincoln and Cadillac grabbed the spotlight this week at the New York Auto Show in a dramatic fashion that evoked the brands' glory days. America's two luxury carmakers went toe-to-toe with their glittering reveals and plans for ambitious expansion. Both were selling their technology, style and the promise of a better future. Cadillac vs. Lincoln. At the Javits Center, 2015 seemed a lot like 1956. Neither company was interested in drawing comparisons with the other, which is fair, and accurate. They're in vastly different places in terms of sales and the pace of their turnarounds, but they hope to reach the same eventual destination at the pinnacle of the luxury-car world. Lincoln used the element of surprise to great effect with the Continental concept. A production version is still at least a year away, and the company was vague on details. Officially, we don't even know if it is front- or rear-wheel drive, though speculation abounds. Who cares? The seats can be adjusted 30 ways! The Continental also showed off a bold chrome grille that will be the new face of Lincoln. The blue bomber also rolled on blinged-out 21-inch polished aluminum wheels, used a 3.0-liter EcoBoost engine and had huge LED head lights with "laser-assisted" high beams. All of this resulted in almost blinding attention. The concept drew rave reviews, stirred controversy with Bentley designers who argued Lincoln ripped them off, and most importantly, pointed a way forward for the newly determined brand that hopes to compete with Mercedes, BMW, Audi, Cadillac and Lexus.

With production starting late this year, Cadillac had more specifics at the ready. Engines? Cadillac has a couple V6s and a turbo four for sure. It's working on a hybrid, and has considered a V-Series variant. It's based on a new rear-wheel-drive, aluminum-intensive chassis called Omega, features an advanced collision-mitigation system with automatic braking and has a cabin that's laden with "leathers, exotic woods and carbon fiber." It will be assembled at GM's Detroit-Hamtramck factory and goes on sale next year. At this point, Cadillac is more than willing to talk about every except for the price. The devil was not in the details for Cadillac, as evidenced by the CT6. But it wasn't for Lincoln either.

Thanks for keeping us on our toes, Detroit Auto Show [w/poll]

Here at Autoblog, we love unexpected debuts at auto shows – and judging by our Detroit Auto Show comments and traffic, you do, too. Surprise reveals have been fewer and farther between in recent years with so many ways for vehicles to be teased or leak out, but this week's show has been a revelation. More to the point, it's been a series of revelations, with automakers from around the globe successfully delivering a brace of concept and production surprises. It's made our jobs a lot more exciting and challenging this week, and even though it's actually more work to react and run-and-gun when the sheet is pulled on a surprise reveal than it is to publish an already-written embargoed story, we've had more fun covering this show for you than any domestic show in memory. We hope you've enjoyed the surprises along with us. To that end, borrowing the words of an unnamed automaker PR flack, we'd like to thank the following automakers for enduring "mountain of antacids" and that "creeping sense of paranoia" necessary to keeping ones' wares totally under wraps until the sheets are pulled off the sheetmetal: Buick Avenir concept Chevrolet Bolt concept Ford GT concept Ford Mustang Shelby GT350R Ford F-150 SVT Raptor Hyundai HCD-15 Santa Cruz concept And while we're at it, we'd like to throw in an shout-out to Detroit's substantially revised and revitalized Cobo Center, and in particular, the redone Michelin media center, which is arguably the single best accommodations for writing show stories that we've encountered on the entire international circuit. Well done, everyone. Thank you, and keep the surprises coming. Auto News Detroit Auto Show Buick Chevrolet Ford Hyundai Volvo 2015 Detroit Auto Show
