GM recalling 250,000 SUVs over door electronics

After a door-fire investigation that dates back to February, the National Highway Traffic Safety Administration has officially announced a recall today that affects around 250,000 General Motors SUVs for a faulty driver's door module. The recall applies to the Buick Rainier, Chevrolet Trailblazer, GMC Envoy, Isuzu Ascender and Saab 9-7X from the 2006 and 2007 model years, as well as the 2006 Chevrolet Trailblazer EXT and GMC Envoy XL for vehicles sold and/or registered in the Snow Belt.
Road salt use in these midwestern and northern states can lead to corrosion of the driver's door module on these GMT360 and GMT370 vehicles, which allows water to come in contact with the circuit board. If shorted out, the vehicle's power door locks and power windows will not work, and could possibly lead to overheating and, in some circumstances, a fire. No official word on how many total vehicles caught on fire, but back in June, 28 fires had been reported to the government agency. A fix for the problem is still being worked out, but all affected vehicle owners will be notified by GM.

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.

CA Chevy dealer allegedly adds $50K 'market value adjustment' to 2015 Z06

It seems to happen with every eagerly anticipated new car – dealerships, recognizing that crushing demand far outstrips the initial limited supply of a new model, inflate the price via a so-called "market value adjustment." We've seen it in the past with a number of new models, and now it's happening again with one of the Detroit 3's hottest vehicles. A dealership in Roseville, CA, outside of Sacramento, has allegedly attached a staggering $49,995 market value adjustment to a 2015 Corvette Z06. We say allegedly because, despite the evidence uncovered by BoostAddict, John L. Sullivan Chevy's online inventory listing doesn't display the price premium of the Z06 in question, a (normally) $93,965 model with the top-end 3LZ trim. It's unclear if either of the dealer's other Z06s, both 3LZs, one of which is in transit, will receive similar price adjustments. Now, legally, Sullivan Chevy isn't doing anything wrong here. Dealerships are under no obligation to observe a manufacturer's suggested retail price, a point General Motors' spokesperson Ryndee Carney pointed out to Autoblog via email. "For the Corvette Z06, Chevrolet has established a Manufacturer's Suggested Retail Price we feel is right for the market. Actual transaction prices, however, are the province of the dealer," Carney said, adding that a dealer zone manager will be discussing the price hike with the dealership. While we also reached out to the dealership over both the market value adjustment and the price of the Z06 as it appears on the company's website, we've yet to hear back as of this writing. Should they reply to our inquiries, we'll be sure to update you. Until then, we'd like to hear what you think about this case. Is Sullivan Chevy simply pricing the cars as high as it thinks the market can bear, or is this a cash grab for an hotly anticipated product? Have your say in Comments.
