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.

Dodge Challenger outsold Mustang, Camaro in third quarter of 2019

The Dodge Challenger is nearly old enough to start driver's ed in some states, and it doesn't have a firm grasp on the increasingly crucial concept of downsizing, yet it beat the odds to become the most popular American two-door model during the third quarter of 2019. Its ballooning sales figures suggest buyers don't always want the latest, most advanced car they can get their hands on. Dodge sold 18,031 examples of the Challenger during the third quarter of 2019, a shocking 21% increase over the same period in 2018. It's a true muscle car, normally sardined in the same can as the Chevrolet Camaro and the Ford Mustang, a pair of smaller, nimbler two-doors that are much closer to the historic definition of a pony car. Semantics aside, the Mustang finished on the second spot of the sales podium with 16,823 sales, a 12.3% drop compared to the third quarter of 2018, and the Camaro took third with 12,275 sales, a 15% dip that alarmingly comes in the wake of two redesigns. More specific sales figures aren't available. We don't know what percentage of the sales mix V8s represent, or whether buyers prefer manual or automatic transmissions. The scoreboard looks different when we examine 2019's year-to-date figures. The Mustang takes first place with 55,365 sales, followed by the Challenger at 46,699, and the Camaro at 36,791. While the Challenger's recent ascent is encouraging, it can't mask the fact that two-door models no longer enjoy a favorable tailwind, and the entire segment — not just the American entries — is declining. The aforementioned year-to-date figures are down by 10.1, 11, and 7.6 percent, respectively. The third-quarter statistics revealed a handful of other surprises unrelated to the world of performance. Dodge notably sold three examples of the Dart, a sedan it hasn't built since 2016. That's a 93% drop compared to the 45 units that found a home during the third quarter of 2018.

How GM engineers are using diaper 'snow' to keep you warm

Testing how snow affects General Motors' vehicles isn't really a problem right now for the company's engineers, but in the dog days of summer the process isn't exactly easy. The only real option is for them to book time at the automaker's climatic wind tunnel. However, a flash of brilliance from an engineer allows snow to be simulated regardless of the temperature outside, and the discovery is all because of his daughter's wet diaper. The realization came to GM Thermal Systems engineer Nicholas Jahn while he was swimming with his daughter and noticed how her diaper ballooned in size in the water. He found out the substance that makes this possible is called sodium polyacrylate. When the material gets wet it grows and forms fluffy flakes that are a close imitation of snow. Best of all, the stuff can be prepared easily any time of the year, and it's reusable. The engineering team uses the material to test the effectiveness of the heating systems of GM's vehicles. They spread the sodium polyacrylate over the inlets at the base of the windshield to obstruct the airflow and then crank the heater. After some time, they can see how much is being sucked into the system and design more efficient systems in the future. See how the process works in the video above and read about the diaper discovery in GM's press release below. Diapers Change Chevy Cruze Winter Warm-up Time GM validation engineer uses diaper material "snow" to reduce frigid drives 2015-01-06 DETROIT – An item commonly found on an infant's changing table is helping General Motors' engineers simulate snow year round, ensuring heating systems in cars like the 2015 Chevrolet Cruze can quickly and efficiently warm its interior. Packed snow can prevent air from entering the inlet panel at the bottom of the windshield, obstructing the flow of air into the heating system and reducing the amount of air it can push out. This can lead to less efficient warming of the car's interior and windshield defrosting. "The last thing anyone wants to do when it's freezing cold out is scrape their windshield," said Nicholas Jahn, GM Vehicle Thermal Systems engineer. "The testing we perform on the Chevrolet Cruze with the diaper material allows us to maximize the car's heating capabilities." Ironically, Jahn stumbled upon his diaper-based testing method in the middle of summer. During a swim with his daughter, he noticed her diaper multiplied in size when it came into contact with water.
