NHTSA closes 4-year GM investigation, issues common sense advisory [w/video]

Since January 2011, the National Highway Traffic Safety Administration has been investigating a possible problem with corroding brake lines in General Motors' GMT800-platform models, like the Chevrolet Silverado and Suburban and GMC Sierra, in states with salt on their roads in the winter. However, as opposed to launching a full recall of millions of vehicles, the government is issuing a common-sense safety advisory to all drivers in snowy states to keep their vehicle's undercarriage clean. It even has a video explaining things. "Older-model vehicles, often driven in harsh conditions, are subject to corrosion over long periods of time, and we need owners to be vigilant about ensuring they, their passengers, and others on the roads are safe," said NHTSA Administrator Mark Rosekind in the announcement of the end of the investigation. The agency was clear in its report that "brake line corrosion seen in the GM vehicles was not unique," and the government "has not identified a defect that would initiate a recall order." Instead NHTSA is advising drivers, especially those of vehicles from before 2007, to wash their vehicle's undercarriage in the winter and spring to remove salt or other de-icing chemicals. It also recommends regular checks by a mechanic to make sure everything is in proper order. According to the investigation documents, for just the GMT800 platform models, NHTSA found 3,645 complaints of brake line corrosion, which included allegations of 107 crashes and 40 injuries. The issue was found to be more common in vehicles over 10 years old. GM has released a statement (embedded below) that the company "supports the consumer advisory from NHTSA urging regular maintenance and care of brake lines on older vehicles." NHTSA Closes Investigation into Brake-Line Failures NHTSA 13-15 Thursday, April 9, 2015 Agency issues safety advisory on preventing undercarriage corrosion WASHINGTON – The Department of Transportation's National Highway Traffic Safety Administration (NHTSA) today issued a Safety Advisory and consumer video encouraging owners of model year 2007 and older trucks, SUVs and passenger cars to inspect brake lines and thoroughly wash the underside of their vehicles to remove corrosive salt after the long winter in order to prevent brake-line failures that increase the risk of a crash.

Electric Cadillac Lyriq, Chevy Bolt EUV and more GM electric cars are on the way

GM’s murky and somewhat secretive electric car plan is falling into place, as the company dumped a massive amount of information about whatÂ’s in the pipeline at an event at its Warren, Michigan campus today. New EVs are going to be popping up across the GM brand lineup, with new entries from Chevrolet, Cadillac, GMC and Buick in progress. We also learned some big news about GMÂ’s new Ultium battery tech today, but check out this story for all of those nitty-gritty details. The electric vehicle onslaught will begin with the Cadillac Lyriq, an electric SUV thatÂ’s already been teased out. Naming it the Lyriq is the news today. No explanation for the name was provided, so weÂ’ll have to wait for April to learn more. GM didnÂ’t specifically say if the Lyriq would be launched at the NY Auto Show, but that show (assuming coronavirus doesnÂ’t cancel it) will begin on April 8 this year. Next up in the order of events is the GMC Hummer electric truck that we know will be launching on May 20. This truck will use GMÂ’s modular Ultium battery technology. However, the wait to buy a GMC Hummer will be a long one, as the truck isnÂ’t going to dive into production until fall 2021 at GMÂ’s Detroit-Hamtramck plant. GM revealed that its new modular Ultium batteries can be configured anywhere from a 50 kWh pack to a 200 kWh pack depending on the application. Range is estimated to be about 400 miles on the upper end with the largest battery pack, and GM continues to boast about a 0-60 mph acceleration time of three seconds. Charging estimates for the Ultium battery-equipped Hummer EV were also provided. GM says its truck platform will have 800-volt battery packs and be capable of 350 kW fast-charging. Time estimates werenÂ’t given, but those numbers suggest the truck will be a rapid charger. The Hummer truck on hand, which was the same that previously starred in GMC's Super Bowl spot, showed off removable roof panels that store in the frunk, as well as what appeared to be a version of GMC's Multi-Pro tailgate. It also featured sail panels on the sides, similar to those in front of the bed of the Chevy Avalanche. In addition to the Hummer, expect to see a couple Chevys launching. GM says the refreshed Bolt EV will be launched “in late 2020” with a refreshed interior and what appear to be thicker front seats.

Autoblog Minute: VW finds CO2 'irregularities', Takata dropped by automakers, SEMA recap

Volkswagen's diesel emissions scandal gets a new wrinkle, US regulators hit Takata Corporation with a substantial fine, and we head to Las Vegas for a look at tuner paradise at the 2015 SEMA show. Autoblog senior editor Greg Migliore reports on this edition of Autoblog Minute Weekly Recap. Show full video transcript text [00:00:00] Volkswagen's diesel emissions scandal gets a new wrinkle. US regulators issue a significant fine to Takata Corporation. And we take a peek inside tuner paradise at the 2015 SEMA show. I'm senior editor Greg Migliore and this is your Autoblog Minute Weekly Recap. The VW diesel emissions scandal, first brought to light in September, gets a new wrinkle, as an internal investigation by the German automaker revealed [00:00:30] irregularities in CO2 emissions that could affect approximately 800,000 vehicles. VW estimates the issue could pose a 2-billion euro economic risk. VW claims that most of the vehicles affected have diesel engines, but industry analysts say a 1.4-liter gas engine is also affected. VW says that fuel consumption figures were set too low during the CO2 certification process. During all of this, sales of some diesel-powered Volkswagen, Audi, and Porsche models [00:01:00] have been halted. Takata Corporation is back in the news in connection with its deadly airbag scandal. Federal regulators fined Takata $70 million. If the parts supplier does not comply, the fine could balloon to $200 million. Takata was also dropped this week by its biggest customer, Honda. And now, Toyota and Mazda will be following Honda's lead in dropping Takata. We're also hearing that Mitsubishi and Subaru are considering a switch in air-bag inflator suppliers. SEMA 2015 [00:01:30] came and went. We saw offerings from Mopar, like the AWD Challenger concept. Honda unveiled a Ridgeline that it will race at the Baja 1000, which gives us a hint at what future production model could look like. The celebrity presence was also felt in Vegas as it always is. Kid Rock brought a Duramax Diesel Chevy Silverado, and Acura restored and presented Ludacris with his now famous 1993 Acura Legend. Those are the highlights from the week that was. Be sure to come back on Saturday for my full recap, [00:02:00] where I'll have some added insight into Hyundai's foray into the luxury sector. For Autoblog, I'm Greg Migliore.
