GM recalling 1.4 million older vehicles for oil leak fire risk

General Motors is recalling 1,411,332 older vehicles with its 3.8-liter V6 yet again due to a fire risk. Specifically, there are 1,283,340 of them in the US, and the affected models are the: 1997-2004 Pontiac Grand Prix 2000-2004 Chevrolet Impala 1998-1999 Chevrolet Lumina 1998-2004 Chevrolet Monte Carlo 1998-1999 Oldsmobile Intrigue 1997- 2004 Buick Regal The fault with these vehicles is that oil can drip onto the hot exhaust manifold during hard braking, which can potentially cause of fire. In the last six years, there have 19 reported minor injuries from this problem but no crashes or fatalities, according to the company. Spokesperson Alan Adler also told Autoblog: "GM has reports of 1,345 fires in vehicles that were repaired under two previous recalls for this issue." At this time, GM is still developing a remedy for the problem. According to Adler, the company advised owners to park these vehicles outside for the previous recalls. "The cars can be safely driven. In cases where a customer reported an engine fire while driving, smoke was reported, which would be an indication of a malfunction," he said. This is GM's fourth recall for this problem since 2008, according to The Detroit News. At one point it was believed that aging valve cover gaskets allowed the oil to leak out and drip onto the manifold. A campaign in 2009 covered nearly 1.5 million of these models through the 2003 model year for the same issue. At the time, dealers installed new spark plug wire retainers as a fix.

GM is working on a remedy. The company is aware of post-repair fires in some vehicles but no crashes or fatalities. There have been 19 reported minor injuries over the last six years. These vehicles with 3.8-liter V6 3800 engines are affected: 1997-2004 Pontiac Grand Prix, 2000-2004 Chevrolet Impala, 1998-1999 Chevrolet Lumina and 1998-2004 Chevrolet Monte Carlo, 1998-1999 Oldsmobile Intrigue and 1997-2004 Buick Regal. Including Canada, Mexico and exports, the total population is 1,411,332.

Sunday Drive: Tracking Tokyo's top performers

The big news of the week mostly came from Tokyo. All of Japan's biggest automakers made waves at the Motor Show, but the winner of the event has to be Mazda. The big Vision Coupe and little Kai Concept stole the show, won our hearts, and earned a ton of attention for the automaker. We can't wait to see how these two concepts impact the design, engineering, and technology of future production models. Take a look at our mega image gallery post below to see everything in high-resolution glory. Interestingly, the single biggest click-magnet of the 2017 Tokyo Motor Show was the BMW X2. We shouldn't be surprised. Crossovers of all shapes and sizes dominate the American marketplace, and the X2 is clearly the most attractive of BMW's even-numbered, coupe-influenced X models. Plus, it's headed for production, with sales starting in the spring of 2018. Moving past the Tokyo Motor Show, Autoblog readers are apparently very interested in the 2019 Chevy Camaro. Spy shots of just about every iteration of Chevy's muscle car lit up the 'net last week, leaving us very interested in seeing what's hiding behind all that camouflage. As always, tune in to Autoblog next week for a front-row seat to all the happenings worth following in the automotive industry. 2017 Tokyo Motor Show | Mega Gallery Mazda Vision Coupe | Tokyo Motor Show's big, sensuous 4-door Mazda Kai concept hints at a more muscular, refined Mazda3 2018 BMW X2 crossover revealed, adorned in gold and silver 2019 Chevrolet Camaro: 1LT, SS, ZL1 all spied with updated styling

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.
